Closed-Loop Extraction: What is It, Benefits, and Downsides?

The major characteristic of the closed-loop extraction system that closes off the air from the solvent during the extraction process and this is what distinguishes it from the open-loop method. The system is a professional set up made up of several apparatuses such as the solvent holding tank, a recovery tank, a scale, and several pumps. The system involves continuous checking of pressure and operating of valves and also allows reuse of the solvents.
