SUBCRITICAL EXTRACTION MACHINE
The basic principle of this process is: in normal temperature and under certain pressure(0.3MPa~0.7MPa), countercurrent extraction the solvent oil for embryo, and mixed solvent in oil and meal vacuum vaporization, after vaporization solvent gas again by compressor condensation liquefied compressed after recycling.
A: Leaching of good quality bread meals, water-soluble protein invariance of more than 95%, residual oil less than 1%, Residual solution less than 50ppm.
B: low Solvent loss, solvent consumption less than 7kg/t.
C: Do not need to steam, only 90° c of hot water can. Compared with the 6th solvent, it can save 70% of heat energy.
D: No three wastes pollution, belongs to environmental protection engineering.
E: colour and luster of the extracted grease is shallow, lecithin content is low, Residual solution is less than 1ppm.
F: Room temperature extraction, low-temperature desolventizing, the heat-sensitive substances of the leaching meals and oils does not damage.,
G: Small investment, low production costs, working pressure is less than 0.7 MPa (Relative to the CO2 device).
H: The sub-critical fluid originates broadly and have competitive price. It is widely used in oil fields and refineries.
I: Low working pressure(less than 0.7MPa), big scale( processing materials 5kg~200tons per day).
Thus sub-critical fluid extraction technology, is a high-efficiency, low energy consumption, environmental protection, safety, has broad application prospects of new technologies extraction of effective components in natural products.
