Supercritical CO2 Extractor Unit


● Supercritical CO2 extraction technology is the latest subject in modern chemical separation and it is an advanced separation technology rising in the world. The so-called supercritical fluid is the thermodynamic state liquid which is above the critical point and the critical point is the point at which the gas-liquid interface just disappears. The supercritical fluid has a very unique physical and chemical properties, its density close to the liquid, viscosity close to the gas.The big diffusion coefficient, low viscosity, big dielectric constant and other characteristics make its separation effect better, so it is a good solvent. Supercritical extraction, namely, under high pressure and appropriate temperature, solvent contact with the material in the extraction vessel, the solute diffuses into the solvent, and then in the separator change the operating conditions to separate out the dissolved substance in order to achieve separation purposes.


● 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.
