Lanphan Cbd Oil Closed Loop Extraction Machine

A closed loop extractor mainly serves as the cannabis extraction equipment widely used in chemical, metallurgical, food and other industries.  The equipment 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.

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.
