Forged Closed Loop Extraction Machine

As an essential extraction equipment, closed loop extractors mainly serve as the cannabis extraction equipment widely used in chemical, metallurgical, food and other industries. There are several types of closed loop extractors. According to 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. But all of them have the basically same structure. 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 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 closed loop extraction system is very economic and energy-saving. In the closed loop extraction system, materials can be reused again and again, which means more energy are saved and can avoid wasting. What’s more, the closed loop extraction system is much safer and possesses an extremely high efficiency.
