Lab Supercritical Co2 Extraction Machine

Lab Supercritical Co2 Extraction Machine

• Gases in fluid condition (above the critical pressure and the critical temperature) dissolve larger quantities of substances than the partial pressure of the substance in the solvent normally permits
• CO₂ is an APOLAR solvent, which results in a high solubility for non polar and low polar substances up to a molecular weight of 250g/molSolubility decreases with increasing polarity
• Highly polar substances are insolubleThe raw material is exposed to the fluid and soluble substances are transferred into it
• Separation is achieved by change of parameters (pressure and temperature) or adsorption into, for instance, active coal

General information
1.1 This system is multi-function SCFE equipment, the working mode is intermittent or continuous way to extract solvent from solid or liquid material, the additive can be add to the supercritical fluid;
1.2 The system has one extractor and two separators
1.3 The max working pressure of solid extractor is 500bar, the highest working temperature is 80ºC;
1.4 The design of pressure vessels according the related national standard and rule demand and with over pressure protection system which means enough safety valves;
1.5 The whole equipment beauty, safety and easy operation, pressure temperature flow number can be showed from pressure meter and digital instrument. The material of pipe parts, valves, pipe lines, are all SS304.

supercritical co2 extraction Advantage

• CO₂ is inexpensive, not combustible, not explosive, germicidal, free of bacteria, selective and mobile
• Heat sensitive materials are gently treated
• Products and residues are solvent-free
• Fragrances and aromas remain unchanged
• An excellent flavour profile can be achieved for oils
• Pure extracts are produced with few process steps
• The solvating power can be changed (conditions, or the use of modifiers)
• Selective extraction and fractionated separation is possible
• CO₂ is recycled within the plant, is physiologically harmless and does not cause environmental problems like some conventional solvents
