Hydrocarbon cannabis extraction is a process that uses a hydrocarbon solvent, such as butane or propane, to extract cannabinoids and terpenes from cannabis plant material. Chillers play a critical role in this process by providing the necessary subzero temperatures, as low as -100F, for efficient extraction.
Why Chillers Are Essential
- Solvent Cooling: Chillers are used to cool the hydrocarbon solvent to a very low temperature before it is introduced to the cannabis material. This cold solvent helps to improve the extraction efficiency and purity of the final product.
- Solvent Recovery: Passive recovery is one of the primary methods used to recover solvent vapors and condense them following the extraction process. It’s a relatively simple process that involves allowing ultra low temperatures provided by a chiller to collect the liquid hydrocarbon solvents using thermodynamics.
- Temperature Control: Chillers help to maintain a consistent temperature throughout the extraction process. This is important for ensuring optimal extraction results and preventing the degradation of cannabinoids and terpenes.
- Product Quality: The use of chillers can contribute to the production of higher-quality cannabis extracts with improved potency and flavor profiles.
