To succeed in today’s demanding pharmaceutical manufacturing environment, a tablet coating process must be as efficient as possible. This means that each step or aspect of the coating process must be optimized to suit the requirements of the specific product being coated, including how the tablets are fed into and discharged from the coater and how the coater is cleaned between batches or products. Optimizing each of these steps will minimize process time and ensure high-quality coated tablets despite variations in batch size or the depth of the tablet bed in the coating drum.

Tablet Feeding

The tablet feeding process transfers uncoated tablets from a storage container to the tablet coater drum. An optimized feeding process should be quick but gentle enough to prevent damage to the tablets. Pneumatic transfer processes should be avoided because they subject uncoated tablets to excessive mechanical stress and damage, making them a high risk to good manufacturing practice (GMP).

Manufacturers use many types of containers to supply uncoated tablets to coaters. Whichever type of feeding container you use, ensure that the container lifting unit and transition chute are customized to suit the coater’s feed opening. When planning a new coating line, consider the tablets’ angle of flow during feeding and the available height of the installation space. Uncoated tablets with poor flow characteristics may require a flow-aid mechanism to ensure complete tablet discharge from the feeding container. For tablets containing highly potent active ingredients, the coater feeding process is subject to a high risk of contamination. Such applications require containment valves and enclosed lines between the feeding container and coater to contain any dust generated during feeding.

The Coating Process

Once the tablets are loaded into the coating drum, the coating process can begin. Tablet coating consists of three sub-processes, or steps: mixing, spraying, and drying. During film coating, the coater executes each of these steps simultaneously; during sugar coating, there are usually separate cycles for adding the sugar solution, coating and mixing the tablet cores, and drying.

Mixing

Thorough mixing is a basic requirement for tablet coating. To ensure an even surface quality throughout the batch, the coater must expose all the tablets to the spray guns with a similar frequency so that they receive approximately the same amount of coating solution. To achieve this, coater manufacturers incorporate baffles on the inside of the drum that act as mixing elements. When developing a coater, the manufacturer carefully shapes these elements and adapts them to the drum geometry, so they create a gentle mixing action in the tablet bed as the drum rotates.

While older coaters were often equipped with large, sometimes height-adjustable, replaceable mixing elements, the mixing elements on modern coaters are significantly lower and fixed, as shown in Figure 1. These lower mixing elements provide a more uniform tablet-bed surface and prevent a wave-like, tumbling action in the tablet bed. The uniform tablet-bed surface prevents tablets from being sprayed at different distances from the spray nozzles, which can excessively moisten tablets at close distances or cause the spray droplets to dry in the air at greater distances.

Because the mixing elements are continuously covered by the tablet bed, they are not directly exposed to the coating spray. This prevents a partial film coating from sugar-coating processes, the mixing elements must not allow the highly sticky sugar-coated tablets any opportunity to get stuck in low- or no-flow recesses in the drum. Ramp-shaped mixing elements, as shown in Figure 2, are particularly suited to this process because they allow the sugar-coated tablets to glide over them, even if the tablets are very sticky.

Spraying

To apply coating solution or suspension to an entire batch of tablets as quickly as possible, it’s beneficial to maximize the number of spray nozzles and/or the tablet-bed surface area that’s exposed to the spray guns during coating. For this reason, drum coaters with an extended drum, a longer spray arm, and more spray nozzles, as shown in Figure 3, have become increasingly popular for film coating processes in recent years. The extended drum flattens out the tablet bed, exposing a greater percentage of tablets to the spray guns during operation.

Depending on the coating solution and the required droplet size, film coaters use either airless or two-substance spray nozzles. Airless nozzles, as shown in Figure 4, create an exceptionally homogeneous spray pattern at high pressure levels. As discussed earlier, it’s critical to maintain the correct distance between the spray nozzles and the tablet bed to prevent either over-moistening the tablets or the coating droplets drying before reaching the tablet bed. Maintaining the correct angle between the nozzles and the tablet bed surface is also critical. Many modern film coaters use auxiliary motors to precisely regulate the nozzle distance and angle automatically without requiring manual intervention by the operator.

Monitoring the spraying process with two-substance nozzles is usually limited to the spray-air pressure, the pattern-air pressure, and the coating solution spray rate. For particularly valuable or highly potent products, the coater may also monitor the liquid pressure in each coating solution line and trigger an alarm, automatic nozzle cleaning, or shutdown if it detects a malfunction such as clogging. Visual control systems with imaging technologies are not currently available but are being developed.

Drying

A modern coating process, as shown in Figure 5, uses optimized, high-volume spray rates that require suitable volumes of treated drying air. The air-line profiles and inlet openings on these systems are designed to keep the velocity of the drying air entering the coating drum low to minimize turbulence and pressure loss across the drum perforation and exhaust air system. Turbulent airflow in the coating drum causes some of the spray droplets to dry before contacting the tablet bed and be carried away in the exhaust airstream. This wastes coating solution and results in longer process times. It also affects tablet quality and limits the number of batches of the same product you can run without cleaning the coater.

The high drying capacity of modern coating systems makes it possible to coat even highly hygroscopic products, such as phytopharmaceuticals or plant extracts, with aqueous solutions. These systems can generate a lot of waste heat, however, so double-walled, insulated coaters that feature air-handling units equipped with heat recovery systems are in high demand. Such systems are not only more energy efficient, they are also safer because they maintain a temperature of less than 60°C on all metal surfaces. Moreover, because the systems mix cold and hot air in the air-supply system, they permit quick and precise temperature control.

Some products may require more complex machine lines with added components, such as a molecular sieve for air drying; a humidifying system or supply-air humidity control; or, for organic solvents, even a closed drying system that circulates inert nitrogen gas. Explosion-protected machine lines such as these can be very complex, particularly if multiple control circuits overlap and safety-related factors, such as a product with a very low minimum ignition energy, significantly affect the procedure.

Tablet Discharge

After coating, tablet discharge should be as quick as possible but gentle enough to prevent damage to the coated tablets. In recent years, helix-shaped welded discharge elements have replaced the special discharge inserts (called “scoops”) that were previously temporarily installed in the coater opening for the discharge process. These modified permanent elements serve as mixing elements when the drum rotates forward during coating but help to remove all tablets from the coating drum without any residue when the drum rotates backward.

For large production coaters, as shown in Figure 6, the number of discharge elements and their volume are selected so that a production batch of several hundred kilograms of tablets can be discharged completely in approximately 10 minutes without operator interference and while remaining gentle to the product.

For containment applications, the contamination risk decreases over the course of the coating process. A risk analysis should determine whether tablet discharge through containment flaps is required or whether no special discharge measures are necessary. In any case, process designers must take suitable measures to ensure that no product dust can emerge from the coater prior to, during, or after the entire coating and cleaning process.

The calculation for the Capacity tablet coating machine:

The capacity of a tablet coating machine in the pharmaceutical industry can be calculated using the following formula:

Capacity = (Tablet weight x Batch size x Coating time) / Coating efficiency

Here are the steps to calculate the capacity:

1. Determine the weight of each tablet. This can be obtained by weighing a sample of tablets and dividing the total weight by the number of tablets.
2. Determine the batch size, which is the total number of tablets to be coated in a single batch.
3. Determine the coating time, which is the total time required for coating a batch of tablets. This includes the time for loading and unloading the tablets, as well as the actual coating time.
4. Determine the coating efficiency, which is the percentage of coating material that actually adheres to the tablets. This can be determined through trial runs and adjusting the machine settings accordingly.
5. Plug in the values into the formula:
   1. Capacity = (Tablet weight x Batch size x Coating time) / Coating efficiency

By following these steps and using the formula, you can calculate the capacity of a tablet coating machine in the pharmaceutical industry.

Critical Parameters of a tablet coating machine

The critical parameters of a tablet coating machine in the pharmaceutical industry are:

1. Inlet Air Temperature: The inlet air temperature is a critical parameter as it affects the drying time and the quality of the coating. The temperature needs to be controlled to ensure the tablets are not overheated, which can cause degradation or melting of the coating.
2. Spray Rate: The spray rate is the amount of coating solution that is sprayed onto the tablets per unit of time. It is critical to ensure that the spray rate is consistent throughout the coating process to achieve a uniform coating thickness.
3. Atomization Pressure: The atomization pressure is the pressure at which the coating solution is sprayed onto the tablets. It is essential to maintain the correct atomization pressure to ensure proper droplet size and distribution, which affects the quality and uniformity of the coating.
4. Pan Speed: The pan speed is the speed at which the tablet bed rotates in the coating pan. The pan speed needs to be carefully controlled to ensure that the tablets are evenly coated and that there is no over-coating or under-coating.
5. Coating Solution Viscosity: The coating solution viscosity is a critical parameter as it affects the spray rate, atomization, and drying time. A high viscosity can result in uneven coating, while a low viscosity can cause the coating to be too thin and easily damaged.
6. Exhaust Rate: The exhaust rate is the rate at which the air is removed from the coating chamber. It is critical to maintain the correct exhaust rate to ensure that the tablets are properly dried and to prevent the buildup of solvents or coating material in the coating chamber.
7. Coating Solution pH: The pH of the coating solution is important as it affects the stability and solubility of the coating material. A pH outside the recommended range can result in a poor-quality coating or even damage to the tablets.

By closely monitoring and controlling these critical parameters, a pharmaceutical manufacturer can ensure that their tablet coating machine is producing tablets with a high-quality, uniform coating that meets the required specifications.
