In the pharmaceutical industry, moisture and oxidation are the two main factors leading to the degradation of drugs, and as one of the important and cutting-edge processes of modern pharmaceuticals - coating process, that is, in a specific device according to a specific process will be able to form a film of certain materials coated with sub-drugs on the external surface of the solid preparations, so that after drying to become closely adhered to the surface of a layer or layers of different thicknesses, different elasticity of multi-functional protective layer, can be used to improve drug stability, masking the bad odor of drugs to reduce irritation, delay and control the release of drugs to prevent the release of drug compounding and improve the appearance and convenience of taking. Achieve the purpose of improving the stability of the drug, masking the bad odor of the drug, reducing the irritation of the drug, delaying and controlling the release of the drug, preventing contraindications of the drug, improving the appearance of the beautification as well as the convenience of taking and many other purposes.
This equipment for coating to become coating machine, is the coating liquid to atomized spray to the material in the rotating state, and through the heating system so that the coating liquid in contact with the surface of the material after rapid drying, and attached to the surface of the formation of a layer of film coat.

Peristaltic pump in the application of pharmaceutical coating

In order to make the surface of the coated drug is detailed and smooth, uniform color, particle size, coating process often need to use the pump to transfer the coating liquid to the atomizer for atomization, and then a certain size of droplets evenly sprayed on the surface of the core. In order to achieve a good coating effect, the coating liquid peristaltic pump used for coating machine has more stringent requirements.
In order to ensure the quality of drugs, the pharmaceutical industry, the entire production process requires accurate fluid transfer and pollution-free production environment. Peristaltic pumps for transferring coating solution should be easy to clean, disinfect and sterilize, in order to meet the requirements of the pharmaceutical industry on the hygiene level of the coating process.
Pumps conveying coating fluid should avoid dead ends, to prevent the accumulation of mixed coating fluid or clogging; peristaltic pumps with stable operating performance, stable flow rate to ensure that the droplet size after atomization is uniform; peristaltic pumps can not destroy the composition, state and integrity of the coating fluid; it should be able to continuously adjust the flow of coating fluid, to be able to adjust the size of the droplets after atomization according to the process requirements, with the drying temperature, the amount of hot air with a view to achieving dynamic equilibrium, to Realize the effect of coating; good corrosion resistance, can be used to transmit corrosive coating liquid.
