Product Characteristics

• Intelligent Control: PLC intelligent control, color touch screen display, digital proportional control technology, device flow, pressure, temperature, flow and other important parameters can be set, memorized and stored directly on the touch screen, which can achieve remote automatic control. Possible combination of automatic control and manual control greatly improves pressure control precision and makes the extracted components purer.

• Overall Layout: A rational structure and modular design make installation and maintenance very convenient;

• Extractor Quick-opening Structure: Adoption of a clamp quick-opening structure (for extraction equipment above 30L) and a pneumatic or hydraulic kettle cover save refilling time; seal material will not swell, can be reused, which improve the utilization rate of the equipment;

• Dryer and Purifier: Able to complete drying and purification of CO2 gas, automatically activate the scavenger; an entrance for trapping agent is provided, and a few substances not separated can be separated from CO2 by adding of trapping agent;

• CO2 Pump: The packing is with high pressure resistance, good sealing performance and a long service life.

• Adoption of a cooling pump head and a cooling plunger chamber make CO2 fluid transfer safer and more

• reliable without phase change; a simple structure and convenient maintenance render a high cost performance;

• CO2 Oxidation and Recycling Function: Improving the utilization efficiency of CO2 and achieving zero emission;

• Refrigerating System: Separate indoor and outdoor system eliminates noise and heat generated by the compressor. An energy-efficient heat exchanger has been used, which greatly reduces the foot space of the refrigerating system.

• Heating System: Steam and electric heating can be chosen for heating, which have high heating efficiency and long service life;

• Automatic Isobaric Switching Function: Pressure balance is not required for kettle replacement, a kettle shall be replaced once extraction is completed, which not only saves pressure balance time, but also increases production capacity of the equipment;

• Hot flushing function: When kettle pressure is balanced, the temperature of the material basket is very low due to depressurization of CO2, which severely affects gasification of CO2 and thereby prolongs the time for pressure balance (CO2 recovery) and material reclaiming is very difficult due to agglomeration, this function can completely solve such problems.
