Principle:

The coating liquid (such as polymer solution) is atomized by the spray system, and dried with hot air to form a thin film on the surface of the rolling material.

Process:

Preheating: The material (such as tablets) is preheated to a suitable temperature in the drum.

Spraying: The coating liquid is evenly sprayed on the surface of the material.

Drying: Hot air quickly solidifies the coating to avoid adhesion.

Cooling: The finished product is discharged after cooling.

Application

Pharmaceutical preparations

Protection and stabilization: Isolate light, moisture or oxygen to extend the shelf life of drugs (such as vitamin tablets to prevent oxidation).
Mask odor: Hide bitter or irritating odors (such as children's antipyretics).
Controlled release: Targeted release through enteric coating or sustained release layer (such as aspirin enteric-coated tablets).
Appearance optimization: Color or polish tablets to improve recognition (such as colored sugar-coated tablets).

Food industry

Flavor enhancement: Add chocolate and spice coatings to candies and nuts (such as chocolate beans).
Shelf protection: Moisture-proof and anti-sticky, extend the crispness of snacks (such as puffed foods).

Softgel Encapsulation Machine

Soft capsule equipment is a special equipment for producing soft capsules, which is widely used in pharmaceutical, health care, food and cosmetic industries. Soft capsules are shells made of gelatin or other polymer materials, filled with liquid, semi-solid or suspended matter.
