5 L cbd supercritical co2 oil extraction machine

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, the maximum working pressure of 40 Mpa.
Carrying agent pump: the maximum flow 10L/h, the 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 users 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 a 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 the corresponding preheater with everybody temperature more steps convergence, more compact structure.

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

9.Flowmeter:

Metal tube flow meter with a 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 a 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 the 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 are 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.
