1、 Equipment Overview:

Single effect external circulation evaporator (single effect concentrator) is an effective form of natural circulation evaporation and concentration equipment. The equipment is widely used in many fields, such as biopharmaceuticals, health food, condiments, dairy drinks, daily chemicals, essence and spices, and environmental protection engineering. It can quickly evaporate and concentrate various materials such as traditional Chinese medicine extract, fermentation broth, enzymatic hydrolysate, protein beverage, chemical solution, etc. under vacuum, effectively increasing the concentration of the materials, or used for the recovery of organic solvents such as alcohol.

2、 Equipment structure composition:

Single effect external circulation evaporator(Single effect concentrator)It mainly consists of a heater, separator, condenser, condensate tank, condensate pump, vacuum pump, material pump, electronic control system, and pipeline system. The main components are all made of304The316L、2205Made of high-quality stainless steel materials.

3、 Equipment working principle:

Single effect external circulation evaporator(Single effect concentrator)During operation, dilute liquid with lower concentration enters the tube side of the heater through the feed pump or vacuum self-priming method. High temperature steam from the boiler enters the shell side of the heater, and the steam indirectly heats the liquid in the tube side. After heating, the liquid boils and rises, and is sprayed into the separator through the spray pipe for flash evaporation. In the separator, the liquid with heavier specific gravity drops to the bottom and returns to the heater through the circulation pipe for further heating. After heating, it boils again and is sprayed into the separator, forming a cycle. The secondary steam with lighter specific gravity rises to the top and enters the shell side of the tubular condenser through the secondary steam pipeline. It is condensed into a liquid phase by the cooling water in the condenser tube side and enters the condensate collection tank. Finally, it is pumped back to the heater. Discharging for recycling or further processing, with a portion of non condensable gas being pumped out by a vacuum pump, When the liquid is concentrated to a certain degree and confirmed to be qualified through sampling, the material can be discharged, completing the process of evaporation and concentration.
