Detailed introduction
　　1. Summary of vacuum scraper concentrator:
　　Vacuum scraper concentrator is referred to as scraper concentrator, or vacuum scraper concentrator, which is a concentrator with scraper mixing system. The vacuum scraper concentrator is suitable for the concentration of liquid materials such as traditional Chinese medicine, western medicine, glucose, starch, monosodium glutamate, dairy products, oral liquid, chemical industry, food, etc., and for the recovery and reflux concentration of alcohol. It is especially suitable for the low temperature vacuum concentration of heat sensitive materials such as ethanol extract and ethanol precipitate. It has the characteristics of short concentration time and fast speed. It can be used in one machine for many purposes, such as atmospheric pressure, vacuum concentration, paste collection and solution. Agent recovery and other operations can also be used for evaporation and concentration of higher concentration liquid, the concentration ratio is significant, up to 1.4.
　　The vacuum scraper concentrator is composed of the main body of the concentrator, the condenser, the cooler, the gas-liquid separator and the receiving tank. The equipment is made of 304/316L stainless steel, which has good corrosion resistance, beautiful appearance and unique structure. Because vacuum vacuum vacuum concentration is adopted, the concentration time is short, and the effective ingredients of heat sensitive materials will not be destroyed. The contact part between the equipment and the material is made of stainless steel, which has good corrosion resistance and durability, and meets the requirements of GMP for pharmaceutical hygiene. The product design is novel and the structure is unique. The scraper blade cooperates with the cylinder body to ensure that the material does not remain. The combination of jacket heat transfer and stirring evaporation is adopted. With vacuum, the speed of evaporation is fast and the heat is uniform. It is suitable for evaporation and concentration of materials with high viscosity.
　　2. Equipment characteristics of vacuum scraper concentrator:
　　The scraper blade used in the vacuum scraper concentrator can be spherical or conical in conjunction with the tank, and the tank body is heated by the jacket structure. The foam trap can effectively capture the liquid foam, prevent foam overflow, and has the characteristics of easy cleaning. The condenser is tubular, which can effectively condense the liquid into liquid, and has the characteristics of easy cleaning. The cooler is a snake tube type, which is easy to clean and can effectively cool the condensated liquid medicine. The surface treatment of the equipment is smooth, and the tank is polished precisely to avoid material stagnation and easy to clean. The production process conforms to the GMP quality standard of pharmaceutical production. The structural design and manufacture of equipment use, operation and maintenance meet the safety design specifications of related equipment.
