Supercritical CO2 extraction machine with three extractors

herb oil extraction machine

The supercritical CO2 extraction machine designed with three extraction kettles has been widely used in industrial production.
The three extraction kettles can work in series and in parallel.
We recommend to perform CO2 extraction in parallel, which has the highest efficiency; because in parallel extraction, there are always two extractors in the CO2 extraction state, and the third extractor is waiting for the next time after unloading biomass.

In this way, 22 extraction batches can be carried out in 24 hours. This is a semi-continuous extraction method, and the CO2 extraction system with three extractors is a very efficient machine.

At the beginning of 2014, we conducted a statistics. There are about 15 sets of supercritical co2 extractors designed with three extractors in China; the minimum volume of a single extractor is 200L and the maximum is 3500L; and these industrial-grade CO2 extraction systems are large Part of the main work is the extraction of vegetable oils.

2100L Supercritical CO2 Extractor

A supercritical CO2 essential oil extraction machine composed of three 700L extractors, used for CO2 extraction of herbal oil, hemp/hemp/hemp oil, and rose essential oil.

The R-700T supercritical CO2 herb extraction machine has three extraction kettles and two separation kettles. The extraction working medium is carbon dioxide. The working medium can be recycled during the working process. It is equipped with a cosolvent system with a flow rate of 100L/h.

The R-700T supercritical CO2 herb oil extraction machine covers an area of ​​about 500 square meters and has a net height of 10 meters. The equipment is fully automatic control equipment. The extraction and separation pressure and temperature are automatically controlled and can be remotely monitored by a computer. Both the series and parallel operations of the valves are manually controlled. During the working process, the maximum working pressure of each extraction kettle is controlled by a four-fold method of pressure detection sensor, safety valve and control signal interlocking, which is safe and reliable.

The R-700T supercritical co2 oil extractor extraction kettle cover adopts a clamp-type hydraulic automatic quick-opening structure. The inner walls, pipes and pipe fittings in contact with the materials are made of stainless steel with acid and alkali resistance and suitable for food hygiene requirements. The equipment in the system to extract the process medium CO2 can be recycled to maximize the use of CO2.

Supercritical CO2 extraction technology is applied to herbal medicine, mainly including extraction and separation, extraction and separation and concentration, removal of organic solvents and removal of impurities.

The supercritical CO2 extraction technology can extract and separate the effective components of traditional Chinese medicine volatile oils, fatty oils, coumarins, terpenes, alkaloids, ketones, esters, etc., which can be basically completed independently, and has unparalleled performance in other technologies. Superiority.

Over the past 30 years, some of the herbal raw materials manufactured by BIT supercritical CO2 extraction device have been tested or produced by BIT:

Ligusticum chuanxiong hort, Angelica, Safflower, Woody, Dalbergia, Cumin, Spice, Peppermint, Houttuynia, Evening Primrose, Nutmeg, Angelica, Turmeric, Magnolia, Alisma, Rhodiola, Artemisia annua, Sand Kernel, Chuanxinlian, Tanshinone, Lycium barbarum seed, Ganoderma lucidum spore powder oil, Propolis, Nicotine, Theophylline, Capsaicin, etc.

CO2 Extraction Machine Buyer’s Guide

As you can imagine, not all supercritical CO2 extractors are made the same.
For more than 30 years, we have customized many CO2 extraction machines (Tabletop CO2 Extractor) for many companies and university laboratories (1 lb CO2 extractor). Because each customer’s CO2 extraction process requirements are different, there are almost no identical machines.

How many liters of CO2 extraction vessels are needed?

The first factor that determines the size of the CO2 extraction vessel is the daily working hours of the plant, which determines the daily extraction batch. The vessel size of the CO2 extractor depends on the biomass to be processed per day.

How many pressure is optimization for your CO2 extraction process requirements?

The choice of CO2 extraction pressure is a changing factor. If the extraction pressure is too high, the useless substances in the plant will be extracted, such as wax and chlorophyll. If the extraction pressure is too low, the extraction time will be increased.

Complete herbal CO2 extraction process steps

  1. Fill Crushed Herbs: Load Extraction Vessel with biomass.
  2. Pressurize with CO2: Bring each vessel to working pressure (supercritical co2 fluid) using CO2 from supply cylinders.
  3. Run in Closed Loop: In Extraction Vessel, compounds are pulled from biomass into solution.
    Solvent (CO2) is boiled out of solution in Separator 1.
    Evaporated CO2 is condensed into liquid and stored in Accumulator.
  4. Periodically Sample Extract: Open separation valve on the separation system to collect extraction samples use the Vessel.
  5. Depressurize: After allotted run time, system is depressurized by releasing CO2 through Separator 2 or Separator 3 (If there is).
  6. Collect Extract: Extract collected from the Vessel.

Because of the stability and flexibility of BIT’s CO2 separation
system, a crude fractionation can be accomplished with the BIT standard herbal essential oil CO2 extraction systems.

BIT CO2 separation systems are capable of modulating the pressure and temperature of CO2. Setting up the desired parameters enables us to manipulate its solvent properties. With the right pressure, temperature, density, and extraction time, we can target the desired compounds we want to extract. This means we can extract the target compounds and separate them into different portions, all in a single extraction cycle!

BIT CO2 extractors are also equipped with several separator (collection) vessels. As the extract laden CO2 exits the extractor vessel it cascades through these separators. The first separator is set at the highest pressure in the series. The 2nd and 3rd separators ramp downwards in pressure. Different molecular weight compounds drop out at different temperatures and pressures, thus allowing for the fractionation to take place in individual separators.

In a standard fractionation scenario, waxes are dropped out in the first separator, heavy oils and resins in the 2nd separator and light oils in the 3rd.
