Grape Seed Oil Extraction Machine

Low Temperature Subcritical Extraction Since the active substances of high added value in natural products are all heat sensitive. When extracting by traditional solvent extraction process, these active substance will be easily destroyed. Supercritical CO2 extraction can get better result, but it must be processed in ultra-high pressure condition which is required to be more than 25 MPa. This high requirements on pressure result in difficulties for realizing industrialized production. Moreover, high cost of equipment and processing making this extraction process hard to be accepted by most businessmen or investors.
