An automatic tablet coating machine is an essential piece of equipment used in various industries, including pharmaceuticals, ayurvedic products, chocolates, food, and chemicals. This machine is designed to apply a coating layer onto tablets or similar solid dosage forms. The coating process can serve multiple purposes, including improving appearance, masking taste, enhancing stability, and providing controlled release of active ingredients. 

An automatic tablet coating machine is vital for the production of high-quality coated tablets in various industries. By optimizing the coating process, these machines enhance product performance, stability, and consumer appeal, making them indispensable in modern manufacturing settings.

Key Components

Coating Pan:

The main chamber where the tablets are placed for coating.

Made of stainless steel to ensure hygiene and easy cleaning.

Designed to rotate, allowing for even distribution of the coating material.

Spray System:

Equipped with a spray nozzle that atomizes the coating solution (liquid) onto the tablets.

Can include multiple nozzles for efficient and uniform coating.

Heating System:

Provides controlled heating to evaporate solvents and enhance coating adhesion.

Often includes hot air blowers or infrared heaters.

Exhaust System:

Removes excess air and vapors generated during the coating process.

Helps maintain a clean working environment and prevents contamination.

Control Panel:

Features user-friendly controls for adjusting parameters such as temperature, spray rate, and pan speed.

May include digital displays for real-time monitoring of the process.

Discharge System:

Automatically unloads the coated tablets once the process is complete.

Can be equipped with a conveyor belt for easy transfer to subsequent processing stages.

Working Principle: - 

1) Tablet Loading:

Tablets are fed into the rotating coating pan.

2) Coating Application:

The coating solution is atomized and sprayed onto the tablets while they are continuously tumbled in the pan.

The spray system provides a fine mist, ensuring an even coating.

3) Drying Process:

As the coating is applied, the heating system evaporates solvents, allowing the coating to adhere effectively to the tablet surface.

This step is crucial for achieving the desired thickness and consistency of the coating.

4) Cooling:

After coating, tablets may be cooled to stabilize the coating and prevent any melting or distortion.

5) Discharge:

The coated tablets are automatically discharged and can be further processed or packaged.

Applications: - 

1) Pharmaceutical Industry: Coatings can mask unpleasant tastes, improve drug stability, and provide enteric protection for sensitive formulations.

2) Ayurvedic Tablets: Coatings enhance aesthetic appeal and can help with the delivery of herbal compounds in a controlled manner.

3) Chocolate Industry: Coating machines are used for creating chocolate-covered tablets, providing a visually appealing finish and added flavor.

4) Food Industry: Used for applying protective or decorative coatings on food tablets or snacks, improving shelf life and consumer appeal.

5) Chemical Industry: Coating machines can also be utilized for coating tablets containing chemicals, enhancing safety, handling, and stability.

Benefits: - 

1) Uniform Coating: Ensures consistent application of coatings, enhancing product quality.

2) Increased Efficiency: Automates the coating process, reducing labor and time.

3) Improved Product Stability: Protects active ingredients from environmental factors.

4) Customization: Different coating materials can be used to achieve specific properties (e.g., enteric coatings, sugar coatings).

5) Versatility: Adaptable for various applications across multiple industries.

Capacities of the Machine is Available from 24" Dia to 72" Dia.
