Low temperature centrifugal alcohol extraction production line

Because the cost of supercritical extraction is very high, in order to meet the different needs of the market, low-temperature alcohol extraction is more and more popular. The finishing process is similar to supercritical extraction, but the front-end extraction is different. Low temperature alcohol extraction first reduces the temperature of the extracted alcohol to minus 40-60 degrees. According to the customer's own process requirements, it is extracted by centrifugation according to a certain ratio of 1:3-5 times. Each batch takes about 20-30 minutes. The extracted solution contains a certain amount of impurities, Filter through two filters, usually 5um and 0.3um, then evaporate most of the alcohol in the solvent through the falling film evaporator, recycle and reuse the alcohol, decarboxylate after falling film evaporation, further decompose the CBD complex into CBD and remove all the residual alcohol, finally enter molecular distillation, further purify CBD, and finally crystallize

It is widely used in the extraction of all organic solvent products, such as herbal extraction, rose essential oil and so on
