50Lx6 Supercritical CO2 Herb Extraction Equipment


● The Super Critical CO2 Herbal Extraction Machine is used for the extraction of material (solid or liquid)under high pressure and suitable temperature extraction.Changing conditions in the separation kettle, the dissolved substances will resolve in order to achieve the purpose of separation.Supercritical CO2 extraction equipment includes several parts: extraction kettle, separation kettle,mixer, CO2 high-pressure pump, co-solvent, refrigeration system, heat exchange system, CO2 storage tank, CO2 level gauge,purification system, flow meter, temperature control system, safety protection system etc.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: 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 In recent years, supercritical extraction technology has got rapid development home and abroad, has realized the industrialized production in hops, spices, herbs, oils, petrochemicals, food health, and other areas.

Preparation Before Switch-Ont

● Check power supply, electric wire to ensure intact. The power supply should be 3phase, 460V/60Hz.

● Check refrigerator, ensure enough water in the water tank.

● CO2 cylinder pressure not less than 5Mpa (Generally during 5-6Mpa). And CO2 cylinders should be full.

● Check all pipeline joints and other joints.

● 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.

● 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%.

● 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.
