The Role Of Tablet Coating Machines In The Pharmaceutical Industry

Tablet Coater :

Tablet coating is the process where coating material is applied to the surface of the tablet to achieve the desired properties of dosage form over the uncoated variety.

The coating is one of the important techniques in manufacturing dosage forms, improving the stability, shelf life, and release pattern. Coating dosage forms help in improving patient compliance. Nowadays, advanced techniques are preferred over the conventional types, because of effective coating, taking less time, and also improving the stability of the product.

Types Of Tablet Coating -

• Film coating.

• Sugar coating

• Press coating.

• Enteric coating.

• Specialized coatings.

Advantages -

• Improving product stability.

• It can maintain the shape of the tablet.

• Improving taste and color of the drug.

• To protect against the gastric environment.

• Reduces friction and increases packaging rate.

• The product has a smooth finish from the coating, making it simple to swallow.

• By providing protection from humidity, heat, and temperature, it maintains the physical or chemical integrity of the medicine.

Disadvantages -

• A trained person is needed to handle the coating process because it is more complex than other processes.

• The main drawback of tablet coating is that the coating process is tedious and time-consuming, which makes it expensive.

R & D Coater :

The R&D Coater has the exterior appearance of an elegant fabricated box with the coating pan supported in a tangential position of 35° to 90°. The entire drive mechanism is concealed within the box leaving only the hub, supporting the coating pan, projected outwards to enable vertical rotary momentum.

Working Principle Of R&D Coater -

Under the influence of a baffle streamline, the tablet that needs to be coated creates a constant complex orbital motion of the closed rotating Drum. While the coating medium is in motion, it automatically sprays by technological procedures and logical technological parameters, and hot, filtered air is provided at the same time under negative pressure.

For the coating medium sprayed on the surface of the tablet cores to dry quickly and evenly, generating a firm and smooth surface film on the tablet, the hot air must pass through the tablet's core layers and be discharged from the bottom of the layers.

Coating Tablet Machine :

A Tablet Coating Machine is equipment that coats the external surface of a tablet using a thin film of coating material.

LDB Coating Machine is widely used for film and sugar coating of tablets in the pharmaceutical and foodstuffs industries.

Tablet coating is the process where coating material is applied to the surface of the tablet to achieve the desired properties of dosage form over the uncoated variety.

The surface coating process is used to produce films, papers, etc. The coating machine is utilized for this procedure. This device is used to apply a layer of glue, paint, or ink to a rolled substrate with specified functionality before cutting or rolling it once it has dried.

Essential Components of a Tablet Coating Machine

Tablet coating machines consist of essential components designed to last and deliver high-quality performance. Coating equipment requires the following machine parts to operate successfully :

1] Automated Control System

2] Electric Motors

3] Touch Screen Operation Panel

4] Peristaltic Pump

5] Spraying System

How to Maintain Your Tablet Coating Machine?

• To keep your tablet coating machine in quality condition, it’s essential to perform the following routine equipment maintenance.

• Every six months, at the very least, the rolling bearings and reducer case should be lubricated.

• Observe the container's temperature.

• Clean the coating pot regularly.

Specification Of Tablet Coating Machine -

• The tablet coating machine parameter complies with the Goods Manufacturing Practices (GMP) standard

• The Pharmaceutical tablet coating machine is built by a type of material that is resistant to corrosion, ensuring continuous tablet coating machine operations and reduction of wear out costs

• The tablet coating machine construction is compact, allowing it to occupy a small space.
