The Lyophilization Equipment originated from the vacuum freeze-drying technology in the 1920s. After decades of ups and downs, it has made great progress in the last 20 years. In the 21st century, vacuum freeze-drying technology is increasingly favored by people because of its unparalleled advantages. In addition to being widely used in the fields of medicine, biological products, food, blood products, and active substances, its application scale and field It is still expanding. For this reason, vacuum freeze-drying will become an important application technology in the 21st century.
Freeze-drying equipment is composed of refrigeration system, vacuum system, heating system, electrical instrument control system. The main components are drying oven, condenser, freezing unit, vacuum pump, heating and cooling device, etc. Freeze-drying, or freeze-drying for short, is a method of first freezing water-containing substances into a solid state, and then sublimating the moisture from the solid state into a gaseous state to remove the moisture and preserve the substances.
Several energy-saving advantages of Freeze Dried Fruit Machine:
1. The triple heat exchange plate is used as the internal cooler of the condenser. At the end of the pre-freezing, the condenser has been sufficiently cooled. After the pre-freezing is completed, the vacuum can be started without switching the refrigeration, which can save the time of vacuum.
2. When two compressors are configured, even if one compressor does not work, the condensation surface area of ​​the condenser will not decrease. Because each triple heat exchange plate is provided with four sets of coils, every two coils correspond to a compressor. If one compressor fails or does not work, there is no change in the frost trapping area. Generally, at the end of primary drying and secondary drying, when the load is relatively small, the program will automatically shut down a compressor, so as to achieve energy saving.
3. Cooling water high-efficiency energy-saving device is to use the preheating of compressor cooling water and silicone oil for heat exchange, which can replace the function of electric heating. Not only that, it can also achieve rapid cooling of silicone oil, and at the same time, it can also circulate and heat the thermal oil to defrost.
