Closed-loop extractors can save companies a lot of solvent procurement costs. The equipment operator can continuously reuse the solvent for extraction after extraction. Ideally, no hydrocarbon solvents leak into the atmosphere.
The closed loop extraction system is closed. The closed-loop extractor also prevents the solvent from evaporating into the atmosphere and allows the solvent to be used multiple times without recharging. Being able to control the temperature is crucial, because temperature directly controls the solubility of cannabinoids. The closed loop system can better regulate the temperature. High pressure allows maximum extraction of cannabinoids. The greater the pressure, the longer the interface time between the hydrocarbon solvent and the cannabis plant material. The fully enclosed solvent in the closed loop extraction equipment has a higher pressure capacity. The closed system can operate safely and comply with OSHA standards. But in a closed loop system, if the equipment is maintained and operated in accordance with appropriate standards, there will be no leakage. SecurityĪlthough experts in the cannabis industry consider closed-loop extractors to be one of the most dangerous methods of extracting cannabinoids, because hydrocarbon solvents are flammable pressurized gases. The cannabis industry chooses closed-loop extraction systems because they are safer, more efficient, more cost-effective, and produce higher quality products. This repeated washing extracts as much cannabinoids as possible. The solvent circulates through the system to repeatedly wash the hemp plant material. The closed-loop extraction uses an extraction vessel that is completely closed to the outside atmosphere, so the hydrocarbon solvent used in the extraction will never come into contact with the air. The closed-loop extraction method has high efficiency, clean products, and safer. In recent years, the closed-loop extraction method has become a very popular cannabis extraction method.
The industry also uses this extraction method to extract essential oils for food additives and perfumes.
Compared with other separation methods, the closed-loop extractor has many advantages: non-toxic, harmless, environmentally friendly, non-polluting, non-thermal processing, retaining the active ingredients of the extract without damage or oxidation, large capacity, energy saving, low operating cost, easy to process the product is separated.Ĭlosed loop extraction is not only used in the cannabis extraction industry. The closed loop extractor is the most advanced and safest system that can be used to make all types of cannabis concentrates, including crushed, crumbs, live resins and isolates. The closed-loop extractor is a machine that can extract cannabinoids such as tetrahydrocannabinol (THC), cannabidiol (CBD) and terpenes from cannabis plant materials, so it is also called BHO extractor, subcritical extractor. Our easy-to-use fractional extraction method allows our systems to maintain a cold separator during all stages of the extraction. This preserves volatile oils and terpenes, while producing a very light-colored oil, regardless of the extraction system parameters.The closed-loop extractor uses subcritical fluid as the extractant. Unlike competitive systems that utilize complex multi-vessel fractional separation methods, our systems can perform fractional extractions through both subcritical and supercritical extraction modes. This allows for selective extraction of the lighter molecules in the subcritical mode, and the heavier fractions in supercritical mode.Ĭompetitive systems that employ complex fractional separation require high heat to be applied to the separator vessels in order to get fractions at multiple pressures causing loss of terpenes and thermal degradation.

Yes! Apeks Supercritical systems use a simple separation technique called fractional extraction that takes full advantage of the varying solvency power of CO 2 at different pressures and temperatures.
