The characteristics and working principle of Chengdong Pharmaceutical High-efficiency non-porous coating machine

(I) BGW high-efficiency non-porous coating machine performance characteristics The main drum adopts a mesh-free structure and is completely sealed. The baffle is arranged inside to make the core turn over smoothly, avoiding the debris and the edge; the tube wall and the baffle are mirror polished, which improves the yield. Relatively porous, it has a wider range of applications; it saves energy and accessories; it is easier to clean.

The wind is filtered by the first, middle and high grades to achieve a clean effect of 100,000 grades; the air exhaust is equipped with a bag dust removal device, the dust removal effect is 99%, and the vibration reduction design, the noise is less than 75 decibels, and meets the environmental protection requirements.

Design a special air source exchange system, which can be exchanged between hot and cold according to the process requirements. That is, the fan-shaped air blade can be used for the air inlet or the air outlet. The air hole diameter can be varied from 0.6 to 3.00mm according to customer requirements. Coating.

The explosion-proof lamp of the sight hole is arranged in the drum to make the material in the work clear and visible, and it is convenient to flexibly grasp the process change.

The constant piezoelectric peristaltic pump eliminates the return pipe, automatically balances the output slurry and the spray amount, stabilizes the atomization effect, saves the auxiliary materials, and is simple to clean, has no dead angle, and avoids cross-contamination.

Designed and manufactured for the coating machine, the imported spray gun is easy to operate and easy to control. It requires flexible control of the process requirements. The gun head must have 0.29---0.39Mpa to shoot, the flow, angle and fan surface are adjustable, and the auxiliary material is atomized. The internal and external density of the section is consistent, the particle size is uniform, the atomization is uniform; the spray surface is large; no dripping, no gun blocking, and auxiliary materials are saved. Thanks to feedback from users at home and abroad, it has been well received.

PLC automatically controls the process parameters such as negative pressure, wind flow, temperature, etc., and can arrange multiple sets of process flow in a certain order, and automatically work and store according to the setting, avoiding the error of manual operation.

The air outlet is provided with an anti-backflow device, and the air outlet is closed before the shutdown to prevent the exhaust gas from flowing back in the air exhaust cabinet.

(II) Working principle of BGW high-efficiency non-porous coating machine The core of the film is in the clean and closed rotating drum of the coating machine, and the complex trajectory movement is continuously performed, the turnover is smooth, the exchange is frequent, and the coating medium stirred by the constant temperature mixing tank passes through The function of the peristaltic pump is squirting from the inlet spray gun to the core of the core. At the same time, the hot air filtered by 100,000 grades is introduced by the airway distributor at the center of the drum. Under the action of exhaust and negative pressure, the core is passed through the fan-shaped wind. The paddle is pumped away from the airway distributor damper and discharged after dust removal, so that the coating medium is quickly dried on the surface of the core to form a solid, dense and smooth surface film, and the whole process is completed under PLC control.

(3) BGW high-efficiency non-porous coating machine is suitable for the coating of sugar-coated, organic film, water-soluble film and the like in Chinese, Western medicine, pills, pellets, pellets, water pills, dropping pills, pellets, etc. in the fields of pharmacy, food, biology, etc. Controlled-release coating; it is an electromechanical integration equipment that is beautiful, efficient, energy-saving, safe, clean and easy to clean; all process parameters such as negative pressure and temperature during operation and process are programmable (PLC human-machine interface) Automatic control, easy operation, advanced and reasonable technology. The main engine and cleaning system and the hot air cabinet, the exhaust cabinet and the constant temperature mixing barrel are all made of imported high-quality stainless steel, which meets the requirements of “GMP”.

(4) Auxiliary equipment is equipped with constant temperature mixing barrel electric heating constant heating, at the set temperature, the medium is evenly stirred, built-in filtration, automatic alarm system for water shortage.

Equipped with automatic feeding and discharging device, the feeding, coating and discharging do not need to touch the human hand, and the hygiene requirements are guaranteed to a large extent.

According to customer requirements:

Storage and printing devices: Automatically retain and record the process parameters and processes of each batch, avoiding mistakes and making the difference between batches zero (under the same process parameters and processes).

In-place cleaning: There is a high-pressure spray gun in the coating pot, which can be rotated, and a cleaning nozzle is arranged at the air outlet and the hot air outlet, which is more convenient and easy to clean.

Color touch screen: beautiful and generous.

Automatic powder leakage device: The talcum powder in the process of coating sugar coating can be automatically leaked through this device, avoiding human contact, more suitable for process requirements, and more in line with "GMP".
