1.The influence of the structure and properties of the embryo.
(1) The more complete the destruction of oilseed cells, the better. Good parietal destroys oilseed cells, such as puffed type, which is conducive to the penetration of solvent and the diffusion of oil, and improves the leaching efficiency.gramiyaa wood cold pressed groundnut oil
(2) The material embryo is thin and firm, with small powder and many voids. Small powder, porous and strong extruded material is better than rolling stock.cold press oil extraction
(3) Starch and sugar substances in the embryo are not conducive to leaching, but a certain shell content is conducive to solvent penetration.black seed oil machine
2. The influence of material embryo moisture.
Generally, solvents can only dissolve oil but not water (except alcohols), so if the water is high, the solvent will not easily penetrate into the cell to dissolve the oil. Therefore, proper low moisture is also important. Even when leaching with aqueous polar solvents (such as ethanol, isopropanol, etc.). The adverse effects of moisture must also be considered. The concentration of ethanol leaching oil is 98% to be miscible with oil. And the lower the water content, the more conducive to oil extraction.chekku coconut oil near me
3. The influence of the temperature of the leaching embryo.
The embryo temperature is high, the oil viscosity is low, the fluidity is good, and the leaching efficiency is high. However, it should be noted that the temperature should not exceed the boiling point temperature of the solvent used and preferably close to this boiling point temperature.colavita extra virgin olive oil first cold pressed
When studying the correlation between temperature and moisture, it is found that the influence of moisture is greater. Under the same temperature conditions, such as when the moisture drops from 12% to 8%, the leaching rate can be doubled, while the temperature is 52.5~57.5°C. There is no impact in the range. But the temperature is too low (such as below 40 ° C) will also be greatly affected.fortune cold pressed oil
