How does a Closed Loop Extractor Work?

A closed loop extractor is a device used to extract solvents from solid substance. It’s a loop system. It is widely used for cannabis concentration in industry. In the whole process, there are several parts serving the extraction of solvents. Solvents can be used and recycled in the closed loop extractor, which is very economic for users and very environmentally friendly for people.

What are Parts of a Closed Loop Extractor?

A closed-loop extractor mainly 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.

How does a Closed Loop Extractor Work?

The entire working process of a closed loop extractor can be simply concluded 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 extracted substances 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.

During the entire operation of a closed loop extractor, all the parts of the equipment are coordinated for solvent extraction. Furthermore, the vacuum pump provides a vacuum environment to help materials react smoothly and efficiently, and the recovery pump provides pressure to accelerate the materials’ reacting speed. And solvents can be used and recycled in a closed loop extraction, which is very economical for users and very environmentally friendly for people. The most commonly used solvents are hydrocarbons, such as butane and propane.

What are Applications of a Closed Loop Extractor?

A closed loop extractor is widely used for the extraction and concentration of substances in chemical, biochemical, industrial fields and other fields. In the whole closed loop extraction equipment, people usually use ethanol as the washing solvent to extract substances from the sample materials. And a closed loop extractor is mainly used for cannabinoid extraction. In the process, cannabis leaves will be put into solvent and fully washed by ethanol. During the washing process, the cannabinoid that is soluble will be removed out and then collected in the receiving tank. The extracted cannabinoid can be used as not only medicine, but also entertainment supplies.
