Multi-Effect Evaporation (abbreviation: MEE evaporator) system refers to multiple single-effect evaporators connected together to realize the reuse of waste heat according to the principle of different boiling points of water under different pressures. The types are: multi-effect reduction Membrane evaporator, multi-effect forced circulation evaporator, multi-effect rising film evaporator, multi-effect external circulation evaporator, multi-effect central circulation evaporator, multi-effect combined evaporator, etc. That is, parallel flow), counter-current flow, mixed flow (ie cross-flow), advection flow, and choose different technological processes according to the characteristics of different materials.

Compared with the traditional multi-effect evaporation system, the mechanical vapor recompression (MVR evaporator) evaporation system is a more efficient, energy-saving and environmentally friendly evaporation technology. Its working principle is that after the secondary steam generated by the MVR evaporator is compressed by a mechanical thermal energy compressor (similar to a blower), the pressure is increased by a certain pressure, and the temperature of the steam is also increased (the most stable compression temperature of the compressor at present) To 8 ～ 20 ℃), the compressed steam is returned to the MVR evaporator to continue to be used as a heating source, and it is continuously repeated to keep the evaporation process continuous. The distilled water and concentrated liquid discharged from the system transfer their energy to the incoming liquid through the heat exchanger , The energy is fully recovered. Therefore, the consumption of external fresh steam by the evaporator is greatly reduced, and the fresh steam is only used to supplement the heat loss and the enthalpy of the incoming and outgoing materials.

The continuous crystallizer can realize the continuous feeding and continuous discharging of industrial crystallization production. The discharged crystals are uniform and uniform, the product quality is high, the operation is simple, the energy consumption is reduced, and the cutting area is small.         The crystallizer is a form of heating or cooling of the material liquid, which is the formation of supersaturation. Crystallization is the process of generating a new phase in a supersaturated solution. It involves solid-liquid phase equilibrium, controlling residence time and flow field to precipitate high-quality crystal products A kind of crystallization equipment. Therefore, the crystallizer can be divided into evaporative crystallizer or cooling crystallizer.

Fermentation equipment is one of the most important equipment in microbial engineering. An excellent culture device should be designed with a strict structure, good liquid mixing performance, high mass and heat transfer rates, and reliable detection and control instruments. Get maximum production efficiency. The fermentation equipment is divided into aerobic fermentation tank and anaerobic fermentation tank according to whether the fermentation needs oxygen. However, the actual application in production is mainly aerobic microbial fermentation, so aerobic fermentation tanks have the most types and the most thorough research.

The function of the freeze dryer is to freeze a substance containing a large amount of water in advance to a solid, and then directly sublimate the water vapor under vacuum, and the substance itself remains in the ice shelf when it is frozen, so it is loose and porous The volume is unchanged. It causes the temperature of the product itself to decrease and slow down the sublimation speed. In order to increase the sublimation speed and shorten the drying time, the product must be properly heated. The entire drying is carried out at a lower temperature.
