BGB-C Series High-Efficiency Coating Machine

Samples of Coating Tablets

Applications

Our coating machine is generally used in the production of pharmaceutical and food industry for film and sugar coating of tablet, pill, candy and chocolate. It is a kind of machine with high efficiency, energy-saving, safety and cleaning, it is in conform with GMP standard, also has CE certificate.

Features

1.The control system consist of PLC and touch screen of Siemens, the design is reasonable and programming is flexible, which are adapt to the different needs of pharmaceutical technology,  featuring reliable work, stable performance and is in conform with GMP standard.

2. The spray gun specially designed for the film coating machine with even atomization and large coverage of spray. With the smart universal direction spray head and automatic anti-block design the film coating can proceed continuously and smoothly, thus reduce the coating time and saving coating material.

3. Control and display the negative pressure in the area of coating pan.

4. Control and display supply air speed.

5. Control and display the temperature.

6. Preventing the spray gun from block

7. The memory and the printing function

Working principle:
The tablet cores to be coated make continuous complicated orbital motion within the closed rotating drum under the action of a streamline guide plate. During the motion, coating medium automatically sprays according to the technological process and rational technological parameters, at the same time hot air is supplied under a negative pressure. The hot air penetrates through the tablet core layers and is discharged from the bottom of the layers, so that the coating medium sprayed on the surface of tablet cores will dry rapidly and evenly, thus forming a solid and smooth surface film.

Performance:

1. The control system consists of PLC and HMI. The design is reasonable
And programming is flexible, which are adapt to the different needs of pharmaceutical technology, thus featuring reliable work, stable performance and conforming to the requirement of GMP.

2. Under the action of the agitation of streamline guide plate, the tablet cores are tumbling smoothly and exchanging frequently, thus elimination the phenomenon of tablet cores falling from a high place and the collide, so that solve the problems of broken pieces and chipped edged and also improve the rate of finished products. The narrow surface of the guide plate eliminates the adhesion of coating material on its surface, thus saving the coating material and improving the quality of medicine.

3. The peristaltic pump with constant pressure and variable eliminates the need for a return pipe. The turning radius of the drum varies with the pressure. The slurry output and the quantity of slurry sprayed are balanced from plugging-up, and saving the coating material, moreover the cleaning is simple, without deed corner.

4. The spray gun is specially designed for film coating machine with even atomization and large coverage of spraying. The universal adjustable spray head makes the cleaning mechanism of spray gun unaffected by charge quantity, so that coating can proceed continuously, thus reducing the coating time and saving coating material.

5. Display and control the negative pressure in the coating drum
We have set up a negative pressure detecting point in the upper box of the coating machine and installed a 2300-1kpa pressure differential gauge(made by the USA Dwyer Co) on the operating console, operator can operate the touch screen according to the technological specification (for instance, the negative pressure being 10PA), and control the speed of exhaust fan, so as to control the negative pressure in the drum.

6. Display and control of the speed of heat-supply air
We have set up an air-speed detecting point in the heat-supply air pipe and installed a 2001AV air speed gage(made by the USA Dwyer Co. )on the operating console, the operator can operate the touch screen according to the technologically specified air speed value(8m/s), so as to control the speed of hot air fan and meet the demand for air supply.

7. Display and control of temperature value
Temperature sensors are installed at the air inlet and outlet of the coating machine. After the temperature signal is inputted to the PLC and compared with the set value(90), the heat exchange is automatically controlled, thus achieving the control of coating temperature value.
