Application in pharmaceutical industry: The application of peristaltic pump in pharmaceutical industry is mainly used for drug coating granulation and drug packaging. Spray drying granulator is also called drying granulator and fluidized bed granulator.
It is a machine used to spray special sugar coating on the surface of various granular instant materials and form particles after drying. These granulators themselves are special drying heat sources, which can achieve the purpose of evaporating water.
The relationship between water evaporation and particle formation is dynamic, so the amount of liquid and water to be injected should be very accurate to ensure that the particles have a certain humidity, which is conducive to the perfect formation of particles.
Extended data
Peristaltic pump is used to obtain the required flow, so according to the operation and use of peristaltic pump, it is divided into:
1. Adjustable speed peristaltic pump: It has the basic control functions of peristaltic pump, such as displaying speed, starting and stopping, adjusting direction and speed, filling and emptying, power-off memory, external control input, etc.
2. Flow-type peristaltic pump: In addition to the basic functions, it has added functions such as flow display, flow correction and communication.
3. Distributed peristaltic pump: In addition to the basic control function, it also has the functions of flow display, flow correction, communication, liquid volume distribution, back suction, output control and so on.
4. Customized (OEM) peristaltic pump: With a series of peristaltic pump heads with different flow ranges, customers can design different peristaltic pump driving circuits according to their own equipment requirements.
Advantages of peristaltic pump:
1, pollution-free: the fluid only contacts the pump pipe, not the pump body;
2. High precision: high repeatability and stable precision;
3. Low shear force: it is an ideal tool for conveying shear-sensitive and erosive fluids;
4, good sealing: it has good self-priming ability, can idling, and can prevent backflow;
5. Simple maintenance: no valves and seals are needed;
6, with two-way equal flow capacity; Under the condition of no liquid idling, it will not damage any parts of the pump; Can produce 98% vacuum degree; Without valves, mechanical seals and packing sealing devices, there will be no factors such as leakage and maintenance;
It can conveniently transport solid, liquid or gas-liquid mixed-phase fluid, allowing the diameter of the solid contained in the fluid to reach 40% of the inner diameter of the tubular element; It can transport all kinds of abrasive, corrosive and oxygen-sensitive materials and foods. Only the hose is a component that needs to be replaced, and the replacement operation is extremely simple; The conveyed product does not touch any parts except the hose.
