Low-temperature vacuum evaporation concentrator

The utility model provides a low-temperature vacuum evaporation concentrator. The low-temperature vacuum evaporation concentrator comprises an evaporation tank, a heater, a condenser, a heat pump system, a vacuum device, a temperature pressure detecting device and a controller, wherein the evaporator is a vessel which is made of a food-grade stainless steel material for evaporating a liquid material; the heat pump system is used for respectively providing hot water and condensate water to the heater and the condenser. The low-temperature vacuum evaporation concentrator is simple in structure and practical in function; the vacuum device is used for vacuumizing the evaporation tank, so that the evaporation environment of the liquid material is close to a vacuum environment; the evaporation temperature is controlled to be 25-30 DEG C, the phenomenon that the liquid material is in chemical reaction due to evaporation and concentration is avoided; the internal temperature pressure detecting device and a single chip microcomputer are utilized for automatically controlling the whole evaporation concentration process in a feedback mode, so that the labor intensity is lowered and the product quality is improved.
