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 Welcome to contact me Part List of Super Critical CO2 Extraction Machine The 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, CO1 tank, flow meter, temperature and pressure control (protection) sy.
