Closed Loop Extractors perform extraction of THC or CBD within the extractor. Hydrocarbon solvents are used to strip cannabis or hemp biomass in a sealed system. Also known as a Hydrocarbon Extractor the Closed Loop Extractor is capable of extracting and refining (color remediation and winterization) extracted oils. THC or CBD crude extract is then separated from the solvent within the system, this step of the process is referred to as recovery and utilizes thermal differences and/or mechanical pressure provided from a refrigerant pump to recover the solvent. The Crude oil is then further refined to remove residual solvent and alter end product consistency/ composition.
