  Now that cannabis is transitioning into the legal market in more states, there has been increased interest in perfecting the cannabis extraction process. One step that ’ s key to the quality of the product is the refinement process.   Cannabis is a complex plant comprising over 550 chemical compounds, all having different extracting and drying requirements to preserve their unique characteristics and therapeutic effects. These chemicals are known as cannabinoids, with cannabidiol (CBD) and THC (delta-9-tetrahydrocannabinol) being the most popular.   While most extractive methods are effective, it ’ s important to further refine the raw cannabis extract to develop finished products, including topicals, edibles, vape oils, etc. Here ’ s what you need to know about cannabis extraction refinement to produce high-quality products for your clients.   What Exactly Is Cannabis Extraction Refinement? To extract cannabis, a solvent-based (chemical) extraction process is used...

Closed-loop extraction is not new or unique to the cannabis industry. For many years people have used closed-loop systems to extract essential oils for things like food additives and perfumes. Recently, however, it has become a widely popular cannabis extraction method. Cannabis industry professionals use closed-loop extraction to extract cannabinoids (THC, CBD) and terpenes from cannabis plant material into an isolated concentrate.   Closed-loop extraction is a form of hydrocarbon extraction. However, unlike other variations of hydrocarbon extraction, closed-loop extraction occurs entirely within a closed system, which keeps the solvent from making any contact with the outside atmosphere. Closed-loop systems offers benefits that other extraction methods are unable to provide, such as safety and efficiency. What is Closed-Loop Extraction? Closed-loop extraction uses solvents to extract cannabinoids. In the closed-loop system, solvent moves from a containment tank into an area where...
