Open all the manholes of the extraction tank, remove the inner parts of the tank, and remove the dirt on the inner wall. Another important point is to cut off the power supply associated with the tank. When entering the stainless steel tank, the low voltage explosion proof lamp with voltage not exceeding 12V or 24V shall be used. The stainless steel storage tank shall also be supervised by special personnel.

The general material enters by the spray drying equipment and material heat exchange device in sterilization machine and by preheating, after high temperature high pressure barrel full of material is heated rapidly to, before and after the sterilization temperature and then keep about 3 seconds, and the microbial enzymes were killed quickly. After the material is out of the high temperature barrel, it is cooled by heat exchange with the cold material, and the general temperature is lower than 65 degrees. If the next process needs to increase the temperature, it can be achieved by regulating the angle stop valve or cycle way, and conversely, the cooling water will be used to reduce the discharge temperature.

The crystallization tank mainly including concentrated tank, condenser, vapor-liquid separator, cooler, the five barrels of liquid components, the concentrator is jacket structure, the condenser is tubular and the cooler is coil type structure. The equipment is suitable for the concentration of liquid in pharmaceutical, food, chemical and other industries, and can be used for recovery of alcohol and simple reflux extraction. The contact parts of equipment and materials are made of stainless steel and have good corrosion resistance, and meet the requirements of GMP standard.
