Tablet Coating Machine

Sinda is a specialized supplier of tablet coating machines. The tablet coating machines are divided into the BYC Series Simple Type Tablet Coating Machines and the BGB series tablet coating machines. The tablet coating machines make a syrup or film materials such as polyvinyl alcohol onto the surface of tablets to improve the taste, ensure stable quality, and provide moisture protection. Tablet coating machines are mainly used in the pharmaceutical and food industries.

BGB Series Tablet Coating Machine

The BGB series tablet coating machine is an efficient and versatile piece of equipment designed for coating tablets, pills, and candies. It is primarily used in the pharmaceutical and food industries to enhance product appearance, recognition, and functionality. The machine can improve the stability of drugs by providing moisture-proof, light-proof, and controlled release properties through the coating film. Additionally, it can cover up unpleasant odors of the product.

Working Principle of BGB Series Tablet Coating Machine

The product to be coated is placed in a clean rotating drum, where it undergoes complex trajectory movements. During this process, the coating medium is automatically sprayed onto the product according to predefined process parameters. Simultaneously, hot air is supplied under negative pressure to quickly and evenly dry the coating medium, forming a strong and smooth surface film on the product.

Features of BGB Series Tablet Coating Machine

1. Advanced Control System:

Composed of a PLC programming system and touch screen control system.
Designed to adapt to various pharmaceutical processes.
Ensures stable operation and complies with GMP requirements.

2. Efficient Peristaltic Pump:

Uses a constant pressure variable peristaltic pump to eliminate the return pipe.
Improves atomization effect and prevents spray gun clogging.
Simplifies the spray system, saves coating materials, and ensures easy cleaning with no dead corners.

3. Streamlined Guide Plate Agitator:

Prevents the product from falling from a height and collision.
Enhances product yield and quality.

4. Specially Designed Spray Gun:

Ensures uniform atomization for a more attractive coating.
Saves coating materials.

5. Control and Display Features:

Displays and controls negative pressure inside the coating pan.
Displays and controls hot air wind speed.

Installation of BGB Series Tablet Coating Machine

Connecting the electricity. Note: the phase line and null line cannot be connected incorrectly.
Connecting the air source with Φ8PU pipe to the pipe connector under the machine.
Fill the coating liquid into the tube.
Start up the electricity switch and put through the electricity.
Adjusting the revolution speed of main machine according to the speeding adjusting devise.
Turn on the wind inlet adjusting switch, wind inlet fan starts working.
Adjusting temperature controller, make the temperature to the wanted figure. If the actual temperature is lower than the set figure, the heater electricity will be connected and starts heating. If the actual temperature is higher set figure, the heater electricity will be cut off and stops heating.
Turn on the switch of spray gun, the gun starts working, for the using instruction please refers to the manual of spray gun.
After each functions above has been adjusted suitably, the air compressor can be opened and the air pressure is about 4-6 kg/cm3.

Maintenance of BGB Series Tablet Coating Machine

The lubricant oil inside reduce and lubricant cream inside the rolling bearing bore should be changed periodically (normally not over 6 months).
If the coating pan is not used for long time, it should be cleaned and coated with oil.
The spray gun should be cleaned by the water with high pressure so to avoid the blocking up of the hole, if it is block, take off the gun head and clean the remains with fine needs with the reference for the instruction manual.
In order to ensures that the worm wheel inside the reducer is in conform to the lubricant condition of transmission, the temperature raise of the machine box can not be over 50 C at working.
The oil proof seal circle of the worm bearing should be inspected and changed periodically.( not over 6 month.)
The machine must be earthed safely, with resistance value: ≤4Ω
Dot not takes off the electrical appliance without allowance.

BYC Series Simple Type Tablet Coating Machine

BYC series simple type tablet coating machines are used for sugar coating and film coating of tablets. The main components include the sugar coating machine, a temperature-controlled hot air system, an automatic liquid system, air supply spray system, and an exhaust system. The main motor is equipped with frequency conversion speed control.

The BYC series simple type tablet coating machines offer several advantages, including a simple structure and easy operation. They create smooth, bright tablet surfaces with a fine coating. Additionally, BY series sugar coating machines save on accessories and are easy to maintain. BY series are an ideal equipment for experiments.

Working Principle of BYC Series Simple Type Tablet Coating Machine

The coating pan rotates clockwise, and the main motor allows for speed adjustment. The coating process takes place in an enclosed space. The solvent dissolves the auxiliary coating materials, and the liquid is sprayed onto the surface of the tablets through a highly atomized spray gun. Simultaneously, the tablets perform continuous complex rolling movements inside the coating pan, ensuring that the solution evenly coats the tablet cores. The controlled hot air inside the pan dries the tablets, while the exhaust fan removes moisture, allowing the tablet surface to quickly form a firm, fine, complete, and smooth coating.

Driving Principle of BYC Series Simple Type Tablet Coating Machine

The main motor drives the worm gear reducer through a V-belt, causing the coating pan to rotate at a reasonable speed. The pan operates smoothly and has self-locking capabilities. The main motor is installed on an adjustable motor plate in a long groove at the rear of the machine, making adjustments convenient.

Maintenance of BYC Series Simple Type Tablet Coating Machine

The lubricating oil in the gearbox and the grease in the bearing chamber should be replaced regularly (generally no longer than six months).
If the coating pan is not used for an extended period, oil should be applied to its surface.
After each shift, the spray gun should be cleaned with water to avoid clogging. If clogging occurs, refer to the manual for disassembly and use a fine needle to remove any residue.
To ensure that the worm gear and worm in the gearbox meet the transmission lubrication requirements, the temperature rise during operation should not exceed 50°C.
The oil seal on the worm shaft should be regularly checked and replaced (every six months or less).
The machine must be grounded, and the grounding resistance should be ≤4Ω.
Electrical equipment must not be disassembled without authorization.
