What is a closed loop extractor?
The closed-loop extractor uses subcritical fluid as the extractant. The closed-loop extractor is a machine that can extract cannabinoids such as tetrahydrocannabinol (THC), cannabidiol (*****) and terpenes from cannabis plant materials, so it is also called BHO extractor, subcritical extractor.
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. 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.
Closed loop extraction is not only used in the cannabis extraction industry. The industry also uses this extraction method to extract essential oils for food additives and perfumes. In recent years, the closed-loop extraction method has become a very popular cannabis extraction method. The closed-loop extraction method has high efficiency, clean products, and safer.
Advantages of closed loop extractor
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 solvent circulates through the system to repeatedly wash the hemp plant material. This repeated washing extracts as much cannabinoids as possible.
The cannabis industry chooses closed-loop extraction systems because they are safer, more efficient, more cost-effective, and produce higher quality products.
Although 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. But in a closed loop system, if the equipment is maintained and operated in accordance with appropriate standards, there will be no leakage. The closed system can operate safely and comply with OSHA standards.
The fully enclosed solvent in the closed loop extraction equipment has a higher pressure capacity. The greater the pressure, the longer the interface time between the hydrocarbon solvent and the cannabis plant material. High pressure allows maximum extraction of cannabinoids. The closed loop system can better regulate the temperature. Being able to control the temperature is crucial, because temperature directly controls the solubility of cannabinoids. The closed-loop extractor also prevents the solvent from evaporating into the atmosphere and allows the solvent to be used multiple times without recharging.
3. Cost saving
The closed loop extraction system is closed. Ideally, no hydrocarbon solvents leak into the atmosphere. The equipment operator can continuously reuse the solvent for extraction after extraction. Closed-loop extractors can save companies a lot of solvent procurement costs.
4. Higher product quality
The closed loop extractor provides precise control of the pressure and temperature in the system to produce the strongest and purest cannabis concentrate. Vacuum purging and heating can remove most or all of the solvent residues, so many consumers also regard by-products as the safest way to eat.
Working principle of closed loop extractor
The closed loop in closed loop extraction refers to a system in which the entire process is completed in a closed container. The solvent used for extraction never comes into contact with the outside atmosphere. In a closed, oxygen-free, low-pressure pressure vessel, based on the principle of similar intermiscibility of organic substances, the extraction material and the extractant are molecularly diffused during the soaking process to achieve The fat-soluble components in the solid material are transferred to the liquid extractant, and then the extractant is separated from the target product through the process of vacuum evaporation, and finally a new type of extraction and separation technology for the target product is obtained. Therefore, the hydrocarbon solvent used to extract cannabinoids will never come into contact with the outside atmosphere.
The main steps of the closed loop extraction system:
1. Solvent All closed-loop extractions start with the solvent used by the operator to extract the oil. It can be butane or propane; most companies agree that food grade ethanol is the safest extraction option. The solvent is cooled in a large tank and then sent through a closed pipe into the compartment where the plant material is stored.
2. Centrifuge This compartment is called a centrifuge, sometimes called a substance column. When the solvent enters the centrifuge, it helps to dissolve the plant matter, thereby extracting oil from it. Some centrifuges also spin to help maximize ethanol recovery.
3. Collection and filtration Solvents and oils must be pumped into a separate container, again using fully insulated pipes, which leaves cannabis crude oil that can be used separately for topical purposes. However, for those who want to make tinctures that can be taken orally, they need to be pumped directly into the filtration system to filter out the third-rate plant substances such as chlorophyll.
Solvents for closed loop extractors
BHO — A Guide to Butane Hash Oil Extraction.
Why Is BHO Different From Other Concentrates?
Butane hash oil (BHO) extraction and resulting products offer certain advantages over traditional whole-flower buds or other extraction methods. Compared to solventless concentrates like kief or rosin, BHO concentrates come in a wider range of consistencies, higher potencies, and can contain a fuller chemical representation of the strain’s original profile. BHO extraction equipment can delicately strip *****’s intoxicating compounds from the plant without damaging the buds’ volatile terpenes. BHO concentrates like live resin or terp sauce are able to retain a higher-than-normal terpene count giving it a richer and fuller flavor compared to concentrates without those aromatic terpenes.
What Is Butane?
Butane is a light hydrocarbon belonging to the same molecular family consisting of ethane, propane, and methane. Butane is produced from crude oils derived from decaying organic matter buried deep underground. Fractional distillation purifies the crude oil and compresses the butane into an odorless and flammable liquid. Professional extraction companies use instrument-grade butane for its purity and low boiling point allowing a more complete cannabis extraction compared to other solvents such as carbon dioxide or ethanol.
