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 is Closed Loop Extraction?
The closed loop extraction can be regarded as a extraction technology that is totally closed to the outside atmosphere. As a result, the solvent used in extraction can’t be exposed to the air, and it can be recycled by a vacuum pump and then come back into the solvent tank for reuse.
How does a Closed Loop Extractor Work?
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.
Are Closed Loop Extractors Safe?
It is well recognized that closed loop extractors is one of the safest equipment to extract cannabinoids. No leak will occur as long as the equipment is maintained and operated properly. But it should be noticed that any mechanical equipment have some safety requirements for use. For a closed loop extractor, you’d better operate it outdoors, which is the safest and most economical environment. It should be guaranteed that the environment temperature isn’t too high and there is no fire or any exposition around.
How much Butane is in a Closed Loop?
The amount of the substance of the product is twice that of the substance of the reactant. The main feature of the closed-loop extraction system is the separation of air and solvent during the extraction process, which is the difference between it and the open-loop method. The system is a professional setup consisting of several devices, such as solvent storage tanks, recovery tanks, scales and several pumps. The system includes continuous checking of pressure and valve operation, and also allows for reuse of solvents.
What are Examples of Closed Loop Systems?
There are temperature control systems (house thermostat) and cruise control systems (in vehicles). Closed-loop control has feedback asynchrony. Through the feedback system, the accuracy of the system is improved and the response time is shortened. It is suitable for the system with high response time and stability requirements.
