20L supercritical co2 fluid extraction machine

The supercritical fluid technology is a new-type separation technology in modern chemical separaton. The supercritical extraction takes CO2 as the solvent, as CO2 fluid under supercritical state has larger density and dielectric constant, larger dissolvability against substances, which can change abruptly when temperature and temperature change therefore it has not only the selection if dissolvability against some substances, the separation of the solvent with the extracted substances is also easily. The supercritical CO2 extraction is specially suitable for extraction of fat-soluble and heat-sensitive substances with high boiling point.
Take CO2 as the solvent to make extraction and purification upon a lot of products such as biological products, foodstuff and medicines.


The supercritical units select the CO2 medium as the supercritical extraction agent, which makes it have the following characteristics:

1. Low critical temperature suitable for extraction and purification of heat-sensitive compound.
2. Being capable to provide inert environment to avoid oxidation of products and affection of effective content of extracts.
3. Fast extraction speed (generally 1-2 hours per run), no toxicity, non-flammable, safe application and no pollution upon environment.
4. No residue of solvent, no nitrate and ions of heavy mental.


Characteristic
  • Wide operating range, easy to adjust
  • Good selectivity, and through controlling the pressure and temperature, targeted extraction of the required ingredients
  • Low operation temperature, the extraction is carried out at a temperature close to room temperature, which is particularly suitable for heat-sensitive components. The extraction process eliminates the possibility of oxidative and photoresponsive reactions, and the extract retains the natural flavor.
  • Only one step from extraction to separation, the CO2 after extraction will not remain in the extracts
  • CO2 is non-toxic, tasteless, non-flammable and easy to get and reused
  • Fast extraction speed

Application


Feature

1.Easy to operate and adjust;
2.Well selectivity. Can extract out requested component according to control pressure and temperature.
3.Low operating temperature. Operation often happen under room temperature, which is much better for Heat-sensitive Materials. Because during extraction process, it has avoid “when oxygen oxygenation” and “when light reaction”, product can keep its natural tastes.
4.Finish within one step, CO2 won’t be left on the products.

5.CO2 is one kind gas of non-poisonous, tasteless, inflammable, cheap and can be cycle use.
6.Quick extraction speed.


CO2 EXTRACTION--HOW TO EXTRACT OIL FROM PLANTS USING CO2 EXTRACTION?

20L supercritical oil co2 extraction machine in herbal extraction
Using high pressure, CO2 is pumped into the first vessel (extraction vessel) containing the plant material. This process converts the CO2 into a liquid, which then passes through the plant material, extracting the oil content. The liquid (CO2 + plant extract) is then pumped into a second vessel (separator vessel) during which the CO2 is converted back into a gas where it separates from the oil. The denser, heavier oil falls to the bottom of the separator vessel into a collection cup. The CO2 continues the loop, circulating around the system, running through the plant material multiple times before the extraction is complete. The CO2 is then redirected back into the gas storage cylinder. Approximately 90% of the CO2 is recycled.

1.The air source part

CO2 gas cylinders (provided by customer), the cylinder pressure generally remain at more than 5 mpa, CO2 purity of 99.99% or higher

2.Cooling part

Refrigeration parts by enclosed refrigeration compressor, storage tank, cold box, temperature controller with spiral coil and tube valve parts, imported compressor.

Cold box is equipped with refrigeration temperature automatic control system and can be arbitrarily set refrigeration required temperature, cold box into the tank, insulation, CO2 coil and stainless steel decorative layer.

Storage tank: 10L/ 16 mpa for liquid CO2 storage.

3.Power supply part

CO2 high-pressure plunger pump:one set

power 2.2 kw, maximum flow is 50L/h, maximum working pressure of 40 mpa.

Carrying agent pump: the maximum flow 10L/h, maximum working pressure of 40 mpa.

4.Purifying filtration system

16 mpa design pressure, volume 1L, the quantity is 1 only, built-in silica gel or other used to filter material, have the effect of filtering, can be put into use in parallel.

5.The extraction kettle

Volume is 5L, the highest working pressure of 40 mpa, maximum operating temperature 80 ℃, two extraction kettle can be used in parallel, with solid material inside the basket (1 in 1 case), material basket of split up and down, convenient discharging, used for extraction of solid material; The heating jacket and insulation kettle body, and is equipped with stainless steel decorative layer. Extraction kettle seal with special structure and special sealing material, structure for sealing, the higher the pressure, the better the self-styled, and fast to open, use for a long time do not need to replace the sealing ring.

6.Separate kettle

Two sets of separate kettle to 2 liters, the highest working pressure are 20 mpa, entrance to be close to the bottom, intubation set heating jacket and insulation kettle in vitro, maximum separation temperature up to 80 ℃.

7.Preheater: the highest working pressure of 40 mpa, the maximum operating temperature 80 ℃, preheater under constant temperature water bath, the water tank with insulation layer, and is equipped with stainless steel decorative layer. Preheater with constant temperature water bath as a whole, reduce the water hot water transmission, and make corresponding preheater with every body temperature more step convergence, more compact structure.

8. Thermodynamic cycle using corrosion and heat-resistant pipeline pump, number 3 only.

9.Flowmeter: metal tube flow meter with secondary instrument, it can display instantaneous flow, and cumulative flow can be shown, it is mainly used for measuring CO2 flow volume.

10.Heating control system

The system is to use temperature controller to set the required temperature, the heat resistance temperature measurement, the feedback signal to the temperature controller, in order to achieve the purpose of temperature control. The extraction kettle, the separator adopts the temperature control of temperature controller.

11.All with vibration-proof pressure gauge pressure gauges.

12. Safety protection device

The device is equipped with electrode point pressure gauge, over-voltage protection, when the pressure rose to the point of electrode pressure gauge set, the control system will automatically cut off the pump power supply, pump stop working, and make the pressure does not exceed the set pressure. In addition, the extraction kettle, separate kettle are equipped with safety valve, when pressure exceeds the pressure of the relief valve set, relief valve on the overflow, the pressure drop and the implementation of pressure protection.

13. Manual and automatic extraction part pressure feedback control:

The distinctive features of the device is in extraction parts both manual voltage regulator, and automatic pressure control section, the manual and automatic dissolve into an organic whole, make the pressure greatly improve the accuracy of setting control, control accuracy can reach 0.5%, the purity of the extracted components is higher.

Preparation before Switch-on

1) Check power supply, electric wire to ensure intact. The power supply should be 3phase, 460V/60Hz.
2) Check refrigerator, ensure enough water in the water tank.
3) CO2 cylinder pressure not less than 5Mpa (Generally during 5-6Mpa). And CO2 cylinders should be full.
4) Check all pipeline joints and other joints.
5) Water tanks (for the heating jacket) should be fulfilled by water free of chloride/ Cl-. And tanks cannot be too full. The water level should be around 2cm distance to the cover of tanks.
6) The material kettle cannot be fulfilled too full. Raw material should be smashed into powder during 20-60mesh. If its size is less than 20mesh, it should be prilled no less than 20mesh. Also, its water content should be less than 10%.
7) Input material kettle into extraction kettle; input material kettle O-ring; input ventilation ring; install plunger; fasten clamps.
8) If co-solvent is used, add it through the co-solvent tank. Use the co-solvent pump.
