Tablet Coating Machine Buying Guide for Importers

Let’s dive right in:

Tablet coating is an important part of general table processing. The process entails the application of a special coating on the surface of the tablet. The coating will remain on the tablet until when the final users will consume the tablet. Therefore, it is not designed to wear off from the tablet.

Tablet coating is done by special equipment that is specifically designed for this job. One such piece of equipment is a tablet coating machine.

Are you planning to buy a tablet-coating machine in China? Then, here is a perfect guide for you. First, we are going to review everything that you should know about tablet coating machines. Then, you will purchase the best machine from a tablet coating machine manufacturer at the end of the guide.

Chapter 1: What is Tablet Coating?

A thin transparent plastic coating, most often a polyimide, is applied over a solid dosage form like a tablet to protect it from spilling or being destroyed in transport. Typically, the thickness of the film is between 20-100 mm.

By utilizing non-destructive analysis methodologies, you can follow the non-custodial handling effects on tablet coating material. The surface tension of the coating will depend on its thickness.

A tablet coating pan is the most convenient and applicable equipment for coating tablets. However, this equipment is somewhat less effective if the coating has not been appropriately cured.

This makes the coating more like plastic tape than a finished film. Therefore, when the coating pan is used to apply the film, it may not provide good adhesion, sufficient drying time, or strength.

The good news is there is an ultimate solution that is used in place of the tablet coating pan. That is a tablet coating machine. The machine has premium features that guarantee the quality coating of the tablets and pills. It also ensures that the quality of the tablets is not affected by the coating.

In addition, a non-custodial handling method like dry mounting, wet mounting, or vacuum infusion is not applicable for what is tablet coating. Dry mounting involves using an aqueous buffer, typically saltwater, between the tablet and the backing sheet. Water adsorb the aqueous solutions causing aqueous solutions to adhere to the backing sheet more tightly.

On the other hand, wet mounting involves applying the coating directly to the aqueous liquid medium and then letting it harden; however, the time required for the drying time is longer.

Chapter 2: Reasons for Tablet Coating

There are numerous reasons for coating tablets. From these reasons, you will be able to appreciate the role that the tablet coating machines play in applying the coatings on the tablets. Some of the top reasons for tablet coating include;

Protect the tablet from stomach acid

The coating on the tablet can protect you from stomach acid by forming a barrier between the tablet and whatever you are eating. The coating keeps the tablet from absorbing things that would otherwise break down the tablet in your stomach.

In addition, some chemicals that are added to the tablet can also form stomach acid in your body, especially if the tablet is coated with some kind of coating.

If you are taking medications that will give you stomach acid, or even if you have a problem with stomach acid, then this coating might be protecting you in more ways than one. First, it will prevent some of the stomach acids from getting into your bloodstream instead, and this can be good because some medications will give you stomach acid if it gets too far.

Of course, the coating on the tablet that protects you from stomach acid is not the only way that it can protect you. There are many other things that the coating added onto the tablet is protecting you from as well, including preventing things like skin oils and lipids from mixing with the tablet.

This can be very important, as lipids are made up of fatty acids and glycerol, which can sometimes mix with tablets and cause a problem with the tablet coating protecting you.

Protects stomach lining from some tablets

If you are taking medication for a stomach ulcer, you can protect your stomach lining by applying a tablet coating to it. A tablet coating is a thin film applied to the inside of an ulcer tablet; this is used in conjunction with a sheet of plastic placed over the tablet and around it.

This protects the inner surface of the tablet from damage from stomach acid. It also protects the stomach lining from harmful chemicals like penicillin and other anti-inflammatory medicines. In addition, such coatings protect the stomach lining from numerous complications that can arise from ingesting tablets.

Tablet coating for delayed release of the medication

Pharmaceutical engineers have been discussing the possibility of using the tablet coating for the delayed release of medication. The coated tablets can maintain their strength and shape for a longer period compared to other tablet forms.

This, in turn, allows for the delayed release of medication that has undergone this type of coating. A tablet coating is used mainly by the pharmaceutical industries to reduce the cost of producing their medication.

When medicine is ready to be released into the market, it is not easy to release it as quickly as possible. Several factors affect the speed of release of the medication.

These factors include the quality of the tablet, the manufacturing process of the tablet, the container in which the medicine is released, and the resistance level of the medication against certain substances.

Tablet coating for delayed release of medication will help improve the quality of the tablet and therefore help improve its overall effectiveness. This type of coating helps improve the strength of the tablet. The resistance level of the medication depends mainly on how well the tablet has been prepared.

Tablet coating to maintain the shape and structure of the tablet

In general, tablet coating is done to give a protective coating on the surface of tablet devices. This is to make the device safe and usable when it is not in use. The main purpose of this coating is to protect the device from bumps, scrapes, or scratches and keep the device dry. If the tablet is not protected properly, then there are chances that it will get damaged and even burst if it gets wet.

There are different types of tablet coating, including friction coating, adhesion coating, and water-based coating. For the most part, friction coating is used to protect the tablet from bumps, scrapes, and scratches.

Adhesion coating is used on the tablet to make it more bendable. Water-based tablet coating is also used to protect the tablet and make it more resistant to wear and tear. In addition, the water-based coating ensures that the device remains dry when it is in use.

Tablet coating ensures the durability of the tablet as well as the safety of the user. If the tablet is not correctly protected, then there is a high chance that it might break into pieces or even burst due to the pressure. The users are at risk of getting hurt or even dying due to such a disastrous situation. So, tablet protection is really important.

Chapter 3: Types of Tablet Coatings

There are different types of tablet coatings in the market. Each coating contains a special type of formulation and is used for purposes. They include;

▣ Sugar coated tablets

▣ Film coated tablet

▣ Gelatin coated tablet

▣ Enteric coated tablet

▣ Compression coating tablet

Let’s look at each type of these coatings and their importance;

1. Sugar-coated tablets

Sugar coated tablet is a tablet preparation containing one or more layers of sugar that have been coated with various substances that promote bonding between the tablet and its backing. Usually, the tablet preparation is done by mixing together various liquors, including spirits, glycerol or propylene glycol, and Xanthan Gum. What’s more, it is also mixed with certain food products like honey, malt sweeteners, maple syrups, rice cereals, corn bran, or tapioca starch.

How is the preparation prepared? Generally, manufacturers buy sugar coating from suppliers in bulk. They then process the powder into various forms depending on the need of the day.

The most popular forms are tablets, chewing gums, chewing pads, and diabetic drinks. This is because sugar coating has a dual function that helps the pharmaceutical industry meet various customer needs by providing a ready-made product at a less high price.

Why is preparation so popular among the pharmaceutical industry? For one, few things can help a company win over competition and grow their business.

And one of them is packaging and delivering their products to the customer with minimum fuss and maximum satisfaction. This is why introducing the ‘sugar coating’ technique to the pharmaceutical industry has helped them achieve this.

2. Film-coated tablet

A film-coated tablet is a thin, polymer-based coating applied to an unformulated solid pharmaceutical dosage form like a tablet. The thickness of such an application is usually no more than 20-mm. By applying non-destructive analysis methods, you can follow the elasticizing physical cure process on film-coated tablet coating.

Film coating ensures that the medicine molecules are deposited uniformly over the whole surface area of the tablet. The surface tension of the film is such that the internal pressure is evenly distributed across the surface area of the tablet. This helps in the proper release of the medicine.

As far as tablet form is concerned, there are two types of films used in the manufacturing of film-coated tablets. These are film-based and non-film-coated tablets. Both these formulations can enhance the quality, safety, and efficacy of the tablets.

The nature of the tablet formulation, type of tablet, use, processing methods, and other parameters must be considered before choosing one over the other.

A major advantage is that these chemical carriers are flexible. This means that various conforms can be obtained while using this material. In addition, it can exhibit a wide range of biological functions such as adsorption, permeability, and even electronic activities such as electrochemical, acoustic, photochemical, and other chemical reactions. These attributes make the film a much sought-after medical device and drug substance carrier.

3. Gelatin-coated tablets

If you have a product that needs to go through a tough processing step, such as gelatin, you will find that gelatin-coated tablet doing for you is very important. One of the first and most common uses of what is gelatin-coated tablet is for pharmaceutical products.

Gelatin is often used in place of glycerine or propylene glycol in medications because it is less irritating for people to work with. When a gelatin coating is added to medicine, it changes the chemical structure of the medicine.

This makes the medicine more effective at treating certain problems and decreasing the effects of other side effects. It can also help to increase the speed at which medicine can be absorbed into the body.

There are two general types of what is a gelatin-coated tablet. The first type is gelatin that has been chemically coated with a substance such as copper sulfate. This allows the gelatin to resist harmful chemicals that are added to it during the manufacturing process.

However, this type of coating does not add any benefit to the product itself, so it is not something that you want to use if you have an allergy to copper sulfate. In addition, you may end up causing more harm to yourself by exposing yourself to the chemicals used to create this coating.

The second type of what is gelatin-coated tablet is gelatin that has been heat-cured. Heat curing allows gelatin to be heated up to almost 100 degrees Celsius before it is placed into a tablet form.

This allows the gelatin to change its consistency depending on the type of tablet that is being used. By using this type of gelatin coating, you will find that you end up with a thicker, longer-lasting tablet than you would by simply using gelatin that has been cold processed.

There are many different manufacturers of what is gelatin-coated tablets that are available on the market today. You will find that some of the manufacturers you will come across will use all-natural ingredients in their products.

In comparison, others are going to use gelatin that has been gelatinized. It is important to understand what each one is offering you when it comes to what is a gelatin-coated tablet.

4. Enteric coated tablets

Enteric-coated tablets are those that have been coated with a gelatinous material that softens and hardens when it comes in contact with the stomach fluid. The enteric coating makes the pill more permeable, which means that the contents can be absorbed easily by the body.

A non-metallic tablet is a tablet coated on its surface by some other material that gives a non-metallic surface that doesn’t penetrate the body. In addition, the non-metallic tablet is usually coated with an organic coating to make them more resistant to chemicals, fungi, and other substances that could harm the tablet if it were to come into contact with it.

The enteric coating of these tablets is essential because of how drugs enter the stomach and get absorbed into the human body. It is also important because some pharmaceuticals have chemical residues on their surface that could affect the absorption of other drugs into the body.

For example, a drug called Travatan is used to treat stomach ulcers. Travatan is a strong antacid and is used to treat those ulcers that occur in the stomach.

The phthalate coating protects the tablet from being ruined by stomach acid, leading to serious side effects. The most popular and common of the two kinds of enteric-coated tablets are polymeric and phthalate-coated tablets.

5. Compression coating tablets

Compression coating tablets are used in the pharmaceuticals to coat the tablets to improve their properties, improve their release profile, enhance their physical and chemical properties, provide protection, enhance lubrication, etc. Most tablet coating manufacturers usually provide the tools and material required for the application process.

The most commonly used tablet coating is the dry rub or wet rub, dry film coating, oil-based coatings, water-based coatings, etc. Many companies specialize in the manufacture and development of tablet coating products. In general, there are two methods to apply the tablet coating: dry-up or wet-up.

This coating method produces a tough, rigid tablet that can be used for various purposes. Generally, this coating process is used for various tableting applications in healthcare, including medications, gels, ointments, gels, suspension solutions, lubricants, oils, etc.

A tablet coating machine is able to apply these types of coatings to your tablet. Once you have decided on the type of coating that you are using, your next step will be to feed the required ingredients, and the machine will be able to deliver the desired results.

Chapter 4: Tablet Coating Machine Working Principle

The working principle of a tablet coating machine is based on the chemical properties of the tablet and the film coating. When the film is applied to the tablet, there must be some kind of solvent present to act as an absorber to allow the penetration of the colorants to the tablet.

The solvent also should have certain chemicals that are able to react with the colors to change the compound. This chemical process is the actual way that the chemical reactions take place to form the colorant into the final product.

One way of examining the working principle of a tablet coating machine is to examine how the different grades of the material react to the solvent being applied to it. As the film penetrates the material, a chemical reaction takes place that changes the compound to the color that is desired. In order for the machine to run correctly, it must be properly set up and the proper solvent present in the appropriate container.

When the tablet coating machine works properly, it will be able to do what it is supposed to do and prevent any undesired effects to the coating or the material to be coated. When this is the case, then the machine working principle has been successfully demonstrated.

This is important to note because if the right solvent is not used, the coating process may not be as effective. For example, when the solvent is too weak, the colors will not be as highly colored or vibrant, and when it is too strong, the finished products will show grainy or uneven finishes.

In order for a coating process to be successful, the correct operating temperature is necessary. Some people prefer to work a room temperature, while others like to work in a cold place where the temperature fluctuates.

Another way to examine the working principle of a tablet coating machine is to examine how the material is applied using the rotary or spray guns. The most common application method is the dry spraying system.

Here are the key activities that take place when using a tablet coating machine:

Identification of ingredients

At this point, you already have your tablets in place. What is required is the selection of the right materials and agents that will be used for the tablet coating. The selection must be very strict to ensure that the coating agent will be compatible with the tablets.

As we have seen, there are different types of tablet coating agents, and each one is used for special cases. Consider the purpose of the tablet coating and then choose the right coating agent.

Also, find out the qualities and the ingredients that have been used on the coating agent, then buy from reliable tablet coating material suppliers.

This step is vital as the quality of the tablet coating material will determine the quality of the final tablets.

Spraying of the coating agent

This is done by using the water-based spray gun, which is responsible for applying the thin layers of coating material that are needed. In this method, there is no need for an additional tool such as an inkjet gun or a water-based paint sprayer. Only a spray gun can achieve this goal.

It is also important to examine how the liquid is sprayed onto the coating tablets. If the water-based solution is used, it should come from a tap, and it should be chilled prior to use. The spray gun should only use water or a very low-pressure system. High pressure can cause the material to clog or explode, so it should be avoided.

It is also important to examine how the thin disks of the coating material are being loaded into the drum. They need to be evenly spaced to evenly coat the tablets. One should not load them too close or too far apart. Most tablet coating equipment have tabs on the side that allow the coaters to be loaded properly into the equipment.

Drying of the coated tablets

The drying process can take place in one of two ways: wet or dry spraying. In a wet spraying process, the material being coated is wet while the drum is spinning at high speeds.

This causes the material to drip down into the drum and makes the coating process slower. In the dry spraying process, the drying can be complete in a few minutes because the drum does not move.

Tablet cooling

After the coating process, tablets tend to have a high temperature. This makes it necessary to be cooled to the desired temperature range. An automated cooling system is usually embedded in the tablet coating machine. It lowers the overall temperatures, which will eventually result in cool and refined tablets.

Unloading the tablets

Once everything is done, the tablets are unloaded from the tablet coating machine. In most cases, the unloading process is automated, whereby the tablets are automatically ejected from the system. The automation saves time and also minimizes any loss of the tablets as they are unloaded.

Tablet coating machines work based on different solid dosage forms for different materials. There are various types of coatings, and each type requires different methods of application. Therefore, the mixing and spraying process needs to be carefully planned out so that the coating machines can perform accordingly.

The mixing and spraying procedures must be performed carefully, and all the necessary controls should be thoroughly implemented. It should be done in a controlled environment to avoid any accidents and to prevent any health hazards.

Of course, the different components of the tablet coating machine are involved in the whole working principle and mechanism of the machine. So, when buying, verify if it has all the required components that will determine its functionality and efficiency.

Chapter 5: Types of Tablet Coating Machines

There are different types of tablet coating machines in the market. While all of them are used for coating tablets, they come in different designs, features, and functionalities. Such attributes can make specific tablet coating machines more convenient for use than others.

The three main types of tablet coating machines include;

▣ Standard coating pan

▣ Perforated coating pan

▣ Fluidized bed coater

Let’s have a brief look at each of these tablet coating machines, and at the end of the day, you will know which one will be suitable for your application area.

1. Standard coating pan

This is one of the most popular types of the tablet coating machine. It has been used for years and easy to use. For instance, this tablet coating machine allows for the easy removal of dried oils, waxes, and other substances left behind after a tablet is made.

A typical standard coating pan is designed to the mounted on an angular stand. It also has a motor that ensures that it rotates at its mounting angle. The continuous rotation of the container forces the tablets to tumble. Meanwhile, there is a spray that is strategically positioned.

A coating solution is applied on the rotating tablet bed. The rotation ensures that the coating solutions spread evenly through the tablets. On the other hand, a heat stream is supplied to the tablet bed to affect the drying of the tablet coating.

Various modifications can be done on the standard tablet coating pans. This can be achieved by adding different accessories such as an immersion sword system and an immersion tube system.

When it comes to what is a standard coating pan for tablet coating, make sure to consider all of your options before deciding.

While there are some brands that are better than others, there are some that are much better than others. The most important factor that will ultimately determine what you purchase is what you want to do with your tablet coating.

1. Perforated coating pan

A perforated coating pan refers to a tubular steel or aluminum tray that contains paper-like particles that are placed over some type of heat source that causes the particles to adhere together, forming a protective layer.

These types of tablet coating machines are typically made from galvanized steel that is coated with an epoxy resin that can withstand any type of chemical agent.

This makes this equipment ideal for use in a wide range of applications, including cosmetic and food applications. Many different brands and types of tablet coating pans exist today, so it is important to know what is available before you begin searching.

An example of a perforated coating pan is the active pharmaceutical tray. Active pharmaceutical ingredients are generally delivered through spray systems in order to avoid contaminations and release the medicine in its pure and original form.

Some companies use hot compressed air to propel the tablets into the pan; however, others prefer dry powder delivery systems. Either way, most active pharmaceuticals are usually released into the system within an aerosol can.

Also, perforated tablet coaters come in different designs and modifications to suit their various areas of applications. The most common designs include;

Hi-coater systems

In these tablet perforators, a stream of dry air is directed into the coating drum. The air passes through a tablet bed, and it gets out through the perforations.

Driacoater

Here, a stream of dry air is introduced into the system through the perforated ribs that are positioned at the periphery of the drum. The coating pan that contains the tablets will rotate to allow the tablets to be exposed to the dry air.

Glatt coater

This perforated tablet coater design features a fully perforated drum. This design helps to guarantee a maximum spraying process. The design also speeds up the process of coating and drying the tablets.

1. Fluidized bed coater

These are the most advanced forms of tablet coating machines for industrial applications. They are mainly used by companies that manufacture large volumes of tablets. They are also called suspension systems since the coating material is applied on the tablets that are freely suspended in the columnar chambers.

The airflow into the columnar chamber is controlled by the system’s control panel. Usually, the tablets will move upward and the airflow downwards. As the air collides with the tablet, the coating material will eventually dry up.

On the other hand, the coating solutions are applied by the rapid spray nozzles, which are positioned at the bottom of the drying chamber. The design of the fluidized coaters provides the optimum conditions for the coating and drying process.

The video below gives a perfect illustration of the different tablet coating machines:

Chapter 6: Parts and Components of Tablet Coating Machine

From the working principle of a tablet coating machine, you can tell that various components are used in affecting the operation of the systems. The key parts of the tablet coater include;

Spray system

In tablet film coating, a spray system is a device that sprays the tablet cores with evenly distributed thin films of water-soluble solution. The tablet core, which has been dried and formed by tablet press (tablet machine), is coated on its surface by spraying the films of active ingredients solution.

The spray system consists mainly of three systems, including the tablet supply part of the tableting machine, the main spraying part, and the coating boom of the tablet film coater.

The tablet core after drying process in tablet press

The spray system consists mainly of three systems, including the tablet supply part of the tableting machine, the main spraying part, and the coating boom of the tablet film coater.

Peristaltic pump

A peristaltic pump is a form of rotating pump found for pumping liquids and gaseous substances, such as air or water. The liquid is usually contained within a small flexible tube-shaped inside an inner cylinder.

The inner cylinder is usually constructed with the help of a mandrel. Peristalsis, which translates to “swinging,” is a natural movement of a fluid through a liquid medium. This kind of pump works through the simple act of pushing a piston from side to side.

The function of this pump in a tablet coating machine is to facilitate the flow of air and even coating material into the coating chamber.

These pumps improve efficiency by reducing viscous losses, which are typically enormous in some industries. The main advantage of peristalsis-pump designs is that they can be easily adapted for many different applications other than in tablet coating machines.

Electric motor

A tablet coating machine has an electrical motor on different components. The motor determines the activities of these different components.

An electric motor is a device that transforms electrical energy directly into mechanical energy. Most electric motors work via the simple operation of a magnetized wire winding around the motor.

The constant attraction-repulsion relationship between the magnetism of the permanent magnet and the electric current induced in a winding produces torque on the shaft of the electric motor.

The torque that the electric motor develops depends on its composition (its design), its size, and the amount of energy that it is trying to convert.

Some of the tablet coating machine parts that have control pumps include;

▣ Peristalsis pump

▣ Coating drum

▣ Air exhaustion unit

▣ Hot air equipment

Guide plate system

The main function of the guide plate is to facilitate a smooth tumbling of the tablets during the tablet coating process. It is a type of magnetic shielding, which is used to cover the inner surface of the tablet to ensure that heat and moisture do not enter the tablet. In a way, it helps the tablet to be protected from disintegration due to heat and also from the effects of moisture.

This type of protective cover is often called a “protector” since it prevents the adhesion of the coating material, a feature that may end up causing tablet disintegration.

Control unit

This component provides a user interface for the interaction between the tablet coating machine and the operator. It allows you to regulate and dictate the operational parameters of the tablet coating machine. It makes it easy to use the tablet coating machine thanks to its touchscreen touchpad.

The control panel has a precise loop control that allows you to select different profiles for the operation of a coating machine. It also features an interactive display unit from which you will get all the visuals of the operation.

The control unit even allows you to record the performance parameters of the tablet coating machine.

Some of the things that a typical control panel does include.

Chapter 7: Common Defects during Tablet Coating and Solutions

A tablet coating process is not always smooth as expected. There are some instances when you may record defects in the operations. Let’s look at some of the problems that you are likely to encounter during the tablet coating process.

▣ Cracking of the tablet coating:The tablet coating process is too aggressive. When the powder falls on a wet surface, you will get some scratches and inconsistencies in the appearance. In this situation, it’s best to either reduce pressure or stop any further flow of material from your hopper into the coating area until everything settles down.

▣ Holes and pores on the tablet coating:There are bubbles that can cause the generation of air in the tablet. Bubbles in the tablet may be caused by ill-fitting equipment or that there was too much powder flow to the coating area.

▣ Hairline cracksare one of the most common defects on tablet coatings. This is often due to overworking of wet material; it can also happen when a batch contains uneven amounts of flaky particles

▣ Chipping of the coatingmay cause the tablet to break during manufacturing. This is often caused by too little dry material in the wet mix or lack of humidity

▣ The coating may peel offfrom one side while it goes through a drying process. It’s usually due to insufficient mixing and can also be a result of improper handling or storage conditions

▣ Oxidationcauses the tablet coating to become brittle and turn brown. This usually happens when there’s too much moisture around the tableting machine during production

▣ The Blooming of the tablet coatingoccurs when the water reacts with some chemicals in the coating. The end result is a dull tablet. It can also be caused by prolonged storage or extremes temperatures. The original color of the tablet coating will no longer be noticeable.

▣ Blistering of the tablet coating surfaceis a major, costly problem. It can occur due to insufficient mixing. The defect reduces the elasticity of the tablet coating material. You can solve the problem by using mild solutions on your tablets. Also, avoid storing the tablets under high-temperature conditions.

▣ Cratering of the tablet coatingsurface is another problem that occurs when the tablet coating material consists of too much water. This defect reduces the strength and elasticity of a tablet coating, ultimately leading to cracking or breaking tablets in manufacturing.

▣ Dullness on the surfacemay occur if there’s insufficient mixing of powder with other ingredients like sugar or starch. It can also happen due to the long storage of the tablet coating material consists of a combination of powder and liquid. You need to keep the tablets moist or wet by mixing in water, sugar, starch, or artificial sweeteners like sorbitol or mannitol. Keeping your ingredients well mixed will also help avoid any problems with dullness on the surface caused by the uneven distribution of the coating.

▣ Color variation of the tablet coatingcan also happen due to the lack of a uniform distribution of ingredients on the surface. A good way to avoid color variation is by using an even, circular motion in your mixing bowl or container.

▣ Poor surface quality Dull, rough or patchy tablet surfacescan be caused by problems with ingredients and mixing. To avoid this problem, always mix thoroughly to ensure all the powder is wet enough before adding any more sugar or any other core ingredient that is used for the tablet coating.

▣ Infilling of the tablet coating:This defect has a very rough surface and is usually caused by too much liquid going into the tablet press.

▣ Tablet coatings that are not uniform in size. This can be due to an uneven distribution of ingredients during mixing or just problems with how the coating material was applied.

▣ Blushing of the tablet coatingis characterized by the appearance of a whitish color on one side of the tablet.

▣ Tablet coating material is not uniformlyapplied over the entire surface. This defect can be caused by either too much liquid going into a tablet press or because when applying the coating material to one area, and it gets onto another piece instead.

▣ The pitting of the tablet coatingis characterized by small, uniform indentations on one side of the tablet. The indentions may be too small that you may not even see them.

▣ Droplets or blisters in the coatingmaterial: This defect can be caused by too much liquid going into a tablet press and getting onto areas that should not have it.

▣ Misalignment of tablet coating:If there are large discrepancies between how big some tablets’ surfaces are, there is a risk of misalignment occurring.

▣ Rough edges at corners: If tablets are pressed with an uneven force, they may come out of their molding process with rough edges at the corners.

The more liquid that is put into a tablet press and onto a tablet surface before it has set up completely, the greater risk there will be.

There are many other ways of helping to prevent problems with tablet coating, and these typically involve the addition of processing aids. Drying agents like magnesium oxide are often added at a ratio of about 0.03% by weight or volume, depending on benchtop tests that have been performed for your particular batch.

Keep in mind that tablet coating defects are often not noticeable on tablets until they reach consumers. This will have a damaging effect on your brand name.

Tablet coating defects are costly to manage and should be addressed as early. This includes contacting a tablet coating machine manufacturer for help or replacing machinery that’s affecting production line efficiency.

Also, buying from reliable tablet coating materials and suppliers will save you from encountering such defects.

Apart from implementing the above solutions, there is one extra step that you may consider taking. That is buying the best tablet coating machines in China. Some of these machines are designed and optimized to minimize common defects in the coating process.

Chapter 8: Where to Buy Tablet Coating Machine

Where you buy a tablet coating machine will always matter. It is obvious that you would always want to buy from the best manufacturers and suppliers. In this chapter, we are going to give you tips on where to buy the best tablet coating machine manufacturers, suppliers, and dealers of the

This is because they will give you the best machine which will always have the right features and functionalities. When it comes to tablet coating machines, there are some points that you should consider;

Source of your tablet coating machine. Check from where the tablet coating machine is coming from. That way, you can determine whether it is a good manufacturer or not.

Be keen because there are many manufacturers and suppliers out there who do not have the best intentions for your business or organization.

Hence, if you want to get the best tablet coating machine, then do some research about that company or manufacturer from where you want to buy that tablet coating machine.

Why is tablet coating done?

Tablet coating is done to improve tablet appearance, tablet stability, and tablet palatability. Tablet coating provides protection from moisture, light, and oxygen, which tablet ingredients may react in a negative way.

Tablet coatings also make tablets more pleasurable to eat by masking unpleasant tastes, textures, or colors. However, the main reason why tablet coatings are used is to get tablet ingredients to adhere better with certain tablet coatings, tablet binders, or tablet fillers.

The tablet binding agent will help the pores of the tablet binders and filler to bond together due to its sticky/tacky nature. This increases tablet hardness which then improves tablet manufacturing efficiency (fewer breakages).

How do you evaluate the performance of the tablet coating machine?

There are various ways of evaluating the performance of a tablet coating machine

Tablet coating machine manufacturers recommend tablet coatings to be used within a specified tablet coating range. The tablet coating concentration of the tablet coating material should also be kept between these ranges for best performance.

Another way of evaluating the performance of a tablet coating machine is tablet tablet-coating effect determination. This is done by tablet coating material and then assessing certain tablet characteristics to determine whether it covered the tablet satisfactorily or not.

What is important in successfully using a tablet coating machine?

The density of the coating layer on the tablet depends upon various tablet tablet-coating conditions. The tablet tablet-coating machine speed and tablet-coating pressure are the two most important factors that affect the thickness of the tablet coating layer on the tablet.

Other factors such as tablet coatings, tablet size, etc., have less influence compared to these two parameters.

How do tablet tablet-coating machine tablet coating speed and tablet tablet-coating pressure affect tablet coatings?

The rate of tablet coating depends on the tablet tablet-coating speed. The tablet coating is uniform if the tablet tablet-coating is at a constant speed or when it has an even increase or decrease from one point to another in tablet tablet-coating.

For example, tablet coating gets thicker when the tablet tablet-coating speed is low and thin when it has an increased tablet tablet-coating rate.

If the tablet compound coatings are very thin (thinner than 0.1mm), they cannot completely cover some of the large particles in tablets, and coating is not even. This makes the tablets with large particles appear uneven, and also some are crusty and thickening.

How to clean the tablet coating machine?

The general principle of the tablet coating machine’s cleaning is to wipe away and clean completely. Therefore, the first step is to remove all dust inside the machine:

Step 3: tablet tablets into the tablet coating machine tablet hopper;

Step 4: tablet coating process start (the cake is rotated / tablet water flow);

Step 5: tablet coating process end, take out the coated tablet mold cavity;

Step 6: The antiscale tablet device in the tablet discharge chute for cleaning [note: this step is usually not publicized by tablet manufacturers, but tablet factory workers know it well];

Step 7: after rotation of the cake into a drying oven to dry and harden, after cooling, the coated tablets are ready for packaging and sale

So for tablet coating machine, from one aspect, it looks like a very simple process (for example, the cake was coated with water at high speed), but in fact, there are many working parts and complex processes, need to interact and coordinate well. Usually, only with a good tablet coating machine operator, tablet manufacturers can realize a qualified tablet product.
