Multifunctional heat reflux extraction and concentration unit can be used in medicine and health, pigments, food and beverage, animals and plants, chemical industry pressure, decoction, immersion, hot reflux, forced circulation penetration, aromatic oil extraction and many other organic solvent recovery kind of process operation. Comply with the GMP standards, mainly used in universities, research institutes and enterprises, research laboratories and small pilot production line. A good solution to the previous laboratory-scale experiments to do extraction and concentration area, long time, ingredients and more problems.

    The herbs into the extraction tank, plus herbs 5 to 10 times a solvent such as purified water, ethanol, etc. according to the requirements of the extraction process in the liquid, the first steam valve open from cans, cooking for about 1 hour, open the vacuum extraction tank liquid pumped into the evaporator heater, open the valve of the first secondary steam heaters, heating evaporation, buffer storage tank valve open and condensate return pumps heat the secondary vapor condensed into the liquid through the preheater extraction tank top spray sprinkler pipe to the tank, continuous cycle 3-4 hours, and finally close the steam valve with the first extraction tank heater secondary steam valve, open the second heater steam valve closed cream.
