Classifications of Closed Loop Extractors:

There are several types of closed loop extractors. In terms of ways of solvent injection, closed loop extractors can be classified into the top filled closed loop extractors and the bi-directional closed loop extractors. In terms of ways of solvent movement, closed loop extractors can be classified into the passive closed loop extractors and the active closed loop extractors.

Working Process of Closed Loop Extractors:

The working process of a closed loop extractor can be described as follows. The materials are put into the material column to get soaked by ethanol or other solvents. In this process, substances get extracted. Then the mixture will be transferred into next column and get separated. The solvents will be transferred into next column and the extract will be saved in the bottom container for users to get. In a closed loop extractor, the solvents can be recycled and used for several times, which is very economical for users and very environmentally friendly for people.

The accessories of closed loop extractors:
01. High pressure food grade hoses: the tube used to transfer liquid phase butane
02. Solvent tank: the container used to contain solvents
03. Product tubes: the tube used to transfer production
04. Collection chamber: the container used to collect oil
05. Recovery pump:used to provide pressure to recover the solvents
06. Material column: the reactor that cannabis gets extracted
