The characteristics and working principle of the coating machine

April 14, 2021

The high-efficiency coating machine is a kind of high-efficiency, energy-saving, safe and clean mechatronics equipment, which can be applied to the pharmaceutical, chemical, food and other industries for tablets, pills, candy, and coating machines. According to the material of the pot, it can be divided into two types: stainless steel and copper. According to the heat exchange efficiency, it can be divided into perforated coater and non-perforated coater.

feature:

1. The control system composed of PLC and HMI has reasonable design, flexible programming, can adapt to various pharmaceutical process requirements, reliable work, stable performance, and meets GMP requirements.

2. Under the action of the streamlined baffle agitator, the flat sheet can be rotated smoothly and frequently replaced, thereby eliminating the phenomenon of flat sheet falling from a height and collision, eliminating debris and knock edges, Increased production. The surface of the deflector is very narrow, which avoids the adhesion of the dressing on the surface, saves the dressing, and improves the quality of the medicine.

3. Constant pressure variable peristaltic pump, canceling the oil return pipe. The gyration radius of the drum changes at any time with pressure changes, and the output slurry and spray volume are automatically balanced, thereby stabilizing the atomization effect, simplifying the spray system, preventing the spray gun from clogging, saving dressings, and easy to clean, without dead ends.

4. The spray gun specially designed and manufactured for coating has uniform atomization and large spray surface. The universal adjustable nozzle is not affected by the filling volume; the spray gun blocks the cleaning mechanism, which can make the coating continuous, shorten the coating time and save the coating dressing.

The coating machine is mainly used for the sugar coating production of tablets and tablets in the pharmaceutical industry. It can also be used for rolling, mixing and polishing of spherical or granular materials in food, light industry and chemical industry. For example: chocolate polishing, peanuts, sugar, seasonings, making glutinous rice balls, pearl powder balls, rolling desiccants, production of chemical fillers, aluminum hydroxide balls, alumina balls, ceramic ball molecular sieves, catalysts. The machine is suitable for outpatient clinics, university laboratories, research institutes, pharmacies and other chemical industries.

working principle

Rotate the pan clockwise to make the sugar-coated tablets tumble, slide, and grind in the pan, and pour the sugar-coated powder into the pan by hand, so that the sugar-coated powder is evenly distributed on all the plain tablets. The included electric blower, the air outlet pipe extends into the ball It can be used for heating, and at the same time, the blower blows hot air to the inner layer of the pan to remove the water on the surface of the tablet, thereby obtaining a stiff sugar coating instead.
