Detail instruction of liquid Supercritical CO2 Extraction Device

This device mainly consists of extraction kettle, separation kettle, fine distillation column, CO2 high pressure pump, entrainer pump, refrigeration system, heat exchange system, purifying system, pressure stabilizing system of extraction kettle, CO2 tank, flow meter, temperature and pressure control( protection) system etc.

I. Detail instractuon of the main parts:

1. Exraction kettle: 0.5L, 1L, 2L, 5L/50Mpa, 10L, 24L/40Mpa, 50-200L/32Mpa, dual purpose for solid and liquid, quipped with the water jacket for circulated heating with adjustable temperature.

2. Separation kettle: 0.3-10L/30Mpa, 50-100L/16-22Mpa, equipped with the water jacket for circulated heating with adjustable temperature.

3. Fine distillation column: According to the technological requirement, 4-section, 6-section or 8-section temperature control are available and relative stuffing can be selected and loaded by customer to technological requirement.

4: High pressure pump: 20L/40Mpa.h double-plunger, 50L/50Mpa.h double-plunger frequency-modulation. 400L/40Mpa.h three-plunger frequency-modulating, the pump head with cooling system.

5. Cooling system: equipped with semi-sealed or full-sealed compressor meet technological requirement.

6. Heat exchange and temperature control system: the heat exchange and temperature control system are equipped for extraction kettle, separation kettle and fine distillation column respectively to control the remperature of water circulation at -85 degree and the temperature of oil circulation at -150 degree. The digital display double-screen is used to control the remperature of water bath and to measure the temperature of CO2 fluid with the accuracy of temperature control at ±1℃.

7: Others: Voltage supply, three phase four wire power with 380V/50HZ and CO2 with foodstuff grade≥99.5% are prepared by customer self.
