img width="370" src="">Cannabis concentrates are a must for brands looking to reach the growing cannabis consumer base. Concentrated cannabis compounds can be used to create a variety of medical and recreational products such as topical ointments, foods, capsules, transdermal patches, suppositories and small batch extracts. While THC concentrate products currently dominate the adult-use market, cannabis-derived CBD concentrates are entering the trending and lucrative health and wellness sector. Manufacturers seeking scalable cannabis extraction solutions must consider their input materials, estimated throughput, equipment capacity, state regulations and product type in order to compete in the highly competitive 'green rush'. Solvent-based extraction is the most viable and efficient method for commercial use.The two most popular solvents are light hydrocarbons (butane and propane) and carbon dioxide (CO2). Let's see how they compare in terms of cannabis extraction for CBD.CO2 cannabis extractionCO2 extraction, also known as supercritical CO2 extraction, is an increasingly popular method for extracting cannabis compounds from raw or trimmed cannabis. https://writeablog.net/conedebt76/what-is-cbd-extract The extraction process is also used in pharmacology, cosmetology and other related industries. The closed-loop CO2 equipment uses a naturally occurring, odourless and colourless CO2 compound that is capable of dissolving cannabis resin from the plant. Using a critical temperature and pressure, the CO2 compound is converted to a supercritical state and adopts properties similar to those of gases and liquids.This supercritical CO2 solvent acts as a gas by filling every nook and cranny of the extraction tube. CO2 also maintains a liquid-like density, which is sufficient to flush out the cannabinoids and terpene compounds. The supercritical CO2 fluid can be passed through the raw material to remove valuable resin trichomes. The compound is "tunable" so that waxes and lipids do not separate from the cannabis oil. Unfortunately, the high temperatures and pressures used in this method can degrade many terpenes and thus significantly alter the unique chemical characteristics of the cultivar.This type of extraction method is often favoured by some for its general affordability, non-toxicity and environmental friendliness. Despite these selling points, CO2 extraction requires time-intensive post-treatment such as antifreezing and fractionation to create a pure product compared to butane hash oil (BHO) equipment, which completely eliminates the risk of residual solvents in the finished product in a much shorter period of time than CO2 extraction. For many manufacturers, the high cost of starting up CO2 extraction equipment can be a deal breaker. In fact, hydrocarbon or BHO cannabis extraction is losing some of its long-standing stigma and rapidly consolidating its position as a superior and more versatile extraction method than CO2 cannabis extraction.BHO cannabis extractionHydrocarbon extraction uses hydrocarbons such as butane or propane to dissolve the trichomes of cannabis. This method is one of the most common and effective extraction methods and is not only applicable to cannabis or hemp.BHO extraction uses engineering peer-reviewed equipment in a Class 1 Zone 1 environment that meets the most stringent standards of the American Society of Mechanical Engineers and the American Petroleum Institute.The hydrocarbon extraction process involves placing the cannabis material into a pressure vessel. Butane or propane is introduced into the vessel to quickly and efficiently extract cannabis oil. The cannabinoid-rich solution is then transferred to another vessel where the butane and propane are separated from the oil. After the butane has been recycled back into the supply tank, a final purification leaves a pure and potent product. The unique refining technology can produce a variety of textures such as e-cigarette oil, active resin and shatter.Shandong Rona Scientific Instrument Co., Ltd. was established in Shandong, China.
