Subcritical extraction technology of date seeds oil
Under certain pressure, the material is countercurrent extraction with liquefied sub-critical solvent, and the solvent in the extraction liquid goes through the evaporation process, so that the solvent vaporizes and the extracted target component is separated to obtain the product; The extracted material evaporates out of the adsorbed solvent, and another product is obtained. The vaporized solvent is liquefied after compression heat transfer and recycled.
Extraction process
1,Pre-process
Date seeds →Crusher Extraction
2,Extraction
3,Refine
Crude oil → Deacidification → Dehydration+decolorization+ deodorization+dewaxing →Finished oil product
Extraction solvent:Butane
Eatraction time: 6h/batch
Features
- Normal temperature extraction, low temperature dissolving, does not destroy the heat sensitive substances in the material, especially suitable for the extraction and processing of heat sensitive materials, the oil obtained is of good quality and high nutrient content; The active substances in the meal remain intact, and the downstream products can be further developed.
- The technology is mature and the demonstration production line built has been in production for 30 years.
- The equipment is a general processing platform, which can extract fat-soluble components in many kinds of materials, such as functional oils, Chinese medicinal materials, spices, fat-soluble pigments and so on.
