This extraction method takes place entirely within a closed container, so the hydrocarbon solvent used to extract the cannabinoids never comes into contact with the outside atmosphere - hence the name "closed-loop extractor".Closed-loop extraction is not new or unique to the cannabis industry. Industry also uses this extraction method to extract essential oils, such as food additives and perfumes. However, in recent years, it has become a popular method of extracting cannabis. Closed-loop extraction is efficient, produces a clean product and is considered by industry professionals to be safer than open-loop or 'open-blast' extraction. Solvents for closed-loop extractorsClosed-loop extractors use hydrocarbons such as butane as a solvent to extract cannabinoids. Butane is the most popular solvent in the cannabis industry - it is a non-polar hydrocarbon with a low boiling point (31.1°F) that allows any residual solvent in the concentrate to boil cold and retains the temperature-sensitive terpenes. Propane can also be used in the extractor. Propane has a low boiling point, is easy to remove and the extraction method is slightly different to that of butane. However, as propane is much more expensive than butane, closed-loop equipment using a mixture of butane and propane is usually found. Mixing butane with propane produces a gaseous mixture which removes additional terpenes and is more effective than using butane alone.The initial process is the same in both open and closed-loop extraction. A pressurised solvent (usually butane) is washed over the cannabis plant matter to extract the desired cannabinoids from the biomass material. In closed-loop extraction, all solvent is then removed from the concentrate in a separate vacuum oven, followed by heating. In open-loop extraction, there is no purging and some butane residue remains in the concentrate. After washing, the oil concentrate can be collected and further refined in a closed-loop extraction, purge/heat. History of closed-loopCannabis extraction is a relatively simple process that people have been using for centuries. Historical documents describe people consuming cannabis-extracted products such as tea, hashish or tinctures. https://anotepad.com/notes/ka483b7d The first recorded mention of hashish is in Egypt in the 12th century. People traditionally ingested hash until the 16th century, when smoking became popular. Hashish arrived in Europe in the 18th century.The science behind cannabis extraction has changed dramatically, but the reasons why people extract cannabis remain the same. Cannabis extracts provide a more potent product and contain more of the desired compounds. Cannabis concentrates are becoming hugely popular, including oils. Cannabis oil is a favourite among cannabis users because it is convenient, consistent and more concentrated. As demand for cannabis products increases, extraction technology continues to advance and the legalisation of cannabis has spurred research and innovation. Essential oil industry discovers closed-loop extractorsClosed-loop hydrocarbon extraction has been used by professionals in the essential oil industry since the 1970s. The US Food and Drug Administration (FDA) considers butane and propane to be food safe ingredients within certain limits. Hydrocarbon extraction is a popular choice for professionals in the cannabis industry as it produces a finished product containing approximately 90-99% cannabinoids. Hydrocarbon extraction can also produce many high quality concentrate products from a single extraction without any further refinement. https://pastelink.net/taw0wuqw For this reason, hydrocarbons are the most commonly used extraction solvent.Many people initially used open-loop extraction methods for cannabis extraction. It is only recently that professionals in the cannabis industry have adopted closed-loop methods to create cannabis concentrates. The development of closed-loop technology represents a paradigm shift in the way producers and consumers approach concentration. Benefits of closed-loop extractorsThe closed-loop method uses an extraction vessel that is completely closed to the outside atmosphere, so the hydrocarbon solvent used in the extraction is never in contact with air. The solvent is circulated through the system and the cannabis plant material is washed repeatedly. This repeated washing extracts as many cannabinoids as possible. Cannabis industry professionals choose closed-loop extraction systems over open-loop extraction systems because they are safer, more efficient, more cost effective and more capable of producing a higher quality product. SaferCannabis? industry professionals consider closed-loop extractors to be one of the most dangerous methods of extracting cannabinoids. Hydrocarbon solvents are flammable pressurised gases. In a closed-loop system, if the equipment is maintained and operated to the proper standards, no leaks will occur. Closed systems can operate safely and comply with OSHA standards.More efficientThe fully closed solvent in a closed-loop extraction plant provides a higher pressure capacity than an open-loop extraction plant. The higher the pressure, the longer the interface time between the hydrocarbon solvent and the cannabis plant material. The high pressure allows for maximum extraction of the cannabinoids. Closed-loop systems are better able to regulate temperature. Being able to control the temperature is vital as it directly controls the solubility of the cannabinoids. The closed-loop extractor also prevents evaporation of the solvent into the atmosphere and allows the solvent to be used multiple times without re-charging.Cost-effectivenessAs the name implies, the closed-loop extraction system is closed. Ideally, no hydrocarbon solvent leaks into the atmosphere. The plant operator can continuously reuse the solvent for extraction afterwards. The closed-loop extractor can save companies significant solvent purchase costs.Higher quality productsThe closed-loop system provides unparalleled control of the pressure and temperature in the system, enabling the production of the strongest and purest cannabis concentrates. Vacuum purging and heating removes most or all of the solvent residue, so many consumers also view the by-products as the safest to consume.
