Compact Tablet Sugar Coating Machine

What Is a Sugar Coating Machine?

A sugar coating machine is pharmaceutical equipment used to apply sugar or film coatings to tablets, pills, or pellets. The BY-300/400 series is an upgraded version of conventional coating machines, designed for easy operation, smooth and glossy surfaces, uniform coating, fine layer formation, and material efficiency. It is ideal for laboratory research, pilot-scale production, and small batch pharmaceutical coating.

This machine integrates a rotating stainless steel coating pan, variable frequency speed control, and a controlled hot air system to optimize coating quality. The main motor's variable frequency control allows flexible adjustment according to tablet size, batch load, and coating type, ensuring that tablets or pellets receive consistent coating thickness and glossy finish.

Coated tablets or pellets from the BY-300 have:
• Strong coating adhesion
• Dense, smooth, and uniform sugar or film layers
• Excellent storage stability
• No additional polishing equipment required

The BY-300/400 is designed for efficient, reliable, and reproducible coating, making it suitable for laboratory use, pilot-scale trials, and small-scale pharmaceutical production, as well as food and confectionery applications like chocolate coating.

How to Use the BY-300 Sugar Coating Machine

1. Load tablets or pellets into the coating pan. Suitable for tablets, pills, or granules.
2. Preheat and remove surface moisture: Activate the heating and hot air system to gently dry the tablet cores before applying any coating.
3. Manual spray coating: Spray sugar syrup or film coating solution in batches while the drum rotates clockwise, ensuring even coverage.
4. Simultaneous drying: After each spray, use hot air to dry the coating layer, preventing sticking, spotting, or uneven coating.
5. Repeat spraying and drying cycles: Continue until the desired coating thickness, color, and gloss are achieved.
6. Unload finished coated tablets or pellets: Stop the machine and collect the coated products.

Note: This unit is equipped with a hot air system; users must provide an air source.

Summary of Coating Sequence:
Preheat & remove water → Spray coating material → Dry with hot air → Repeat until uniform, glossy sugar or film coating is achieved.

Working Principle (Detailed)

The BY-300 works through the coordinated operation of a rotating coating pan and controlled hot air system:

• Tablets or pellets tumble, slide, and polish continuously inside the stainless steel coating drum.
• The heating and heating system gently dries each coating layer without damaging the tablet core.
• Repeated cycles of manual spray coating and hot air drying build a dense, uniform, glossy coating.
• Variable frequency control adjusts drum speed to optimize tablet movement and coating uniformity.
• Tablets achieve even sugar or film coating, high gloss, and excellent adhesion.

Key Process Insight:
To achieve rapid and uniform coating crystallization and polishing, the BY-300 relies on manual batch spraying of sugar syrup or coating solution while the drum rotates clockwise. Tablets tumble, slide, and polish, while hot air removes surface moisture, ensuring every tablet receives consistent coating thickness and bright, defect-free surfaces. The drum is designed to maintain a stable linear speed for optimal material flow, meeting the highest standards for pharmaceutical sugar coating quality.
