A closed-loop extractor kit 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.
Classifications of the Closed Loop Extractor Kit
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.
Advantages of the Closed Loop Extractor Kit
1. High production.
2. More than 99% of the solvent can be recovered.
3. Independent port for vacuum, injection and recovery.
4. Remove the pollution in the solvent and oil.
5. No gas exposed to air.
6. Environmental protection.
7. Modular design for easy upgrade.
What is a Closed Loop Extractor?
The closed loop extraction is known as a well received cannabis extraction method, occurring entirely in a closed vessel. The closed loop extractor is a common equipment for transferring a solute substance from one solvent to another by utilizing the difference in solubility or partition coefficient of the substance in two mutually incompatible (or slightly soluble) solvents. It is widely used in chemical, metallurgical, food and other industries, commonly used in petroleum refining industry. During the entire operation of the closed loop extractor, all the parts of the plant are coordinated for solvent extraction. Solvents can be used and recycled in closed loop extractors, which is very economical for the user and very environmentally friendly for people.
How do you Use a Closed Loop System?
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 closed loop extractor, the solvents can be recycled and used for several times.
