High Productivity Passive 5Lb Closed Loop Extractor

A closed loop extractor primarily consists of three parts: a solvent tank, a material column and a receiving foundation. Some upgraded versions add a dewaxing column as the fourth part, or equip the material column with a dewaxing structure directly. The closed loop hydrocarbon extraction system is used to conduct a plant extraction in a sealed vacuum system. The closed-loop system can be kept during the plant extraction without exposing any solvent to the air. The butane, propane or the combination of them are generally used as the solvent.

A closed loop extractor is the device used to extract solvents from solid substance, especially used for cannabis extraction used in industry. In the whole process, there are several parts serving the extraction of solvents. 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.

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.
