Application of peristaltic pumps in pharmaceutical coating machines

In a specific equipment according to a specific process, some film-forming materials are coated on the outer surface of the solid dosage of sub-drugs, so that after drying, it becomes a layer or layers of multi-functional protective layers of different thicknesses and different elasticities closely adhered to the surface, which can achieve many purposes such as improving drug stability, covering up drug bad odor, reducing drug irritation, delaying and controlling drug release, preventing drug contraindications, improving beautifying appearance and facilitating consumption, which is one of the important processes of modern pharmaceutical coating!RCqRongbai Pump

The equipment used for coating is called a coating machine, and there are many types, mainly including traditional water chestnut coating pot, high-efficiency film coating machine, fluidized bed type coating cylinder, etc. The working principle of various coating machines is basically the same, which is to spray the coating liquid on the material in the rotating state in an atomized manner, and through the heating system, the coating liquid dries quickly after contacting the surface of the material, and attaches to its surface to form a layer of film coating.RCqRongbai Pump

Peristaltic pumps are ideal for coating liquid transfer pumps on coating machine equipment; The peristaltic pump transports liquid materials by extruding the hose, and the liquid materials are only in contact with the inner wall of the pipeline, which can prevent the pump body from contaminating the liquid materials. There are no dead spots on the pipeline, and cleaning, disinfection and sterilization work is simple.RCqRongbai Pump

By using hoses that meet hygienic requirements, contamination-free transmission of materials can be achieved. By replacing the hose, pollution-free switching between different materials can be realized; The peristaltic pump has good self-sealing performance, and there is no need for valves and seals on the pipeline to avoid dead angles; The low pulsation structure design of the peristaltic pump can realize the stable flow transmission of liquid materials; Wide and continuously adjustable flow range, providing different flow rates as process requirements change; The peristaltic pump has low shear force and can transfer liquid materials and macromolecular materials containing solid particles without changing the state of the material; Peristaltic pumps can drive a wide range of hoses with excellent chemical compatibility and can transfer highly aggressive solvents by selecting hoses of the right material.RCqRongbai Pump
