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 (CBD) 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.
1. Security
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.
2. Efficient
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 extractor:
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 marijuana’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.
