What is a Closed Loop Extractor?
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. It is an equipment of 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. It has gained popularity in a great number of fields, because it has high efficiency to providing the pure extracted solvents. It is widely used in industrial cannabinoid extraction. 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.
Classifications 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.
Applications of a Closed Loop Extractor
A closed loop extractor is mainly used to extract the solvent from the solid matter. It is widely used and mainly used in industry, such as extracting cannabis, and extracting cannabinoids from cannabis leaves by ethanol.
With the rapid development of industry, the extraction of ethanol-washed cannabis has become increasingly popular around the world.
Besides, a closed loop extractor is widely used in the production of perfume, make up, all kinds of food, medicine and other products.
How does a Closed Loop Extractor Work?
Closed loop extractors’ working procedures are as follows:
- The closed loop extractor works from its top. The user places the hemp in the top fill inlet, then the solvent washes the hemp in the column of material and then collects the oil as it passes through the material.
- The solvent containing the oil will be collected into the collection chamber under the column of material.
- The solvent will evaporate and recycle in the collection chamber and the oil will remain in the collection chamber.
Throughout the process, the vacuum pump provides a vacuum environment and the recovery pump provides pressure.
Advantages of a Closed Loop Extractor
- High production.
- More than 99% of the solvent can be recovered.
- Independent port for vacuum, injection and recovery.
- Remove the pollution in the solvent and oil.
- No gas exposed to air.
- Environmental protection.
- Modular design for easy upgrade.
What is the Closed Loop Extraction System?
Known as an essential extraction method, the closed loop extraction sysytem is used to extract cannabis concentrates. As its name suggests, there is no solvent being exposed to the open air in the closed loop extarction system.
In recent years, the closed loop extraction system has been more and more popular in the chemical, biochemical, industrial, pharmaceutical and other fields, and it’s especially applicable for the process of food, perfume and other beauty products. And nowadays, the use of closed loop extraction system is well-received in the concentration of Cannabis.
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.
