Closed Loop Extractor Operation
It’s well-known that closed loop extractors are widely used for the extraction and concentration of substances in chemical, biochemical, industrial fields and other fields. It’s especially suitable for the process of food , perfume and othe beauty products. The reasons can be concluded as follows. Firstly, it is safer because of the closed-loop extraction setup. Secondly, it’s energy-saving due to the materials can be reused. Thirdly, it possesses a higher efficiency and better quality, which can separate various substances very quickly and produce the pure extracted solvents. As a result, how to operate closed loop extractors properly is a key question that we need to know. Then, let’s go through the working operation of closed loop extractors together.
- Firstly, users need to put the sample materials into the closed loop extractor from the 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.
- Secondly, after users put the sample materials into the top, the materials will be washed by special liquid to extract the pointed solvents from the sample materials. The solvent containing the oil will be collected into the collection chamber below the column of material.
- After the solvent containing the oil arrives the collecting tank, the oil will stay in the collecting tank and the washing solvent will be transferred back into main reacting column to be reused, which proves the closed loop extractor is energy-saving.
During the whole working process, the vacuum pump provides a vacuum environment to help the materials react smoothly and efficiently, and the recovery pump provides pressure to accelerate the materials’ reacting speed.
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.
