oil press

The main component of crude oil is a mixture of glycerin three fatty acid esters (commonly knows as neutral oil).In addition to neutral oil, crude oil also contains non glyceride substances, and can divided into mechanical impurities, fat soluble impurities and water soluble impurities. Refine crude oil can remove harmful impurities for edible, storage and industrial production. Such as protein, phospholipids, gossypol, mucus, moisture should remove, and beneficial impurities such as tocopherol will hold. Oil refining process: degumming---de-acid---decolor—deodorization—finished oil The main component of crude oil is a mixture of glycerin three fatty acid esters (commonly knows as neutral oil).In addition…

Oil extraction method is using solvent to dissolve the grease, through the wet permeability, molecular diffusion and convective diffusion, to extract oil in the seeds. Oil extraction method is using solvent to dissolve the grease, through the wet permeability, molecular diffusion and convective diffusion, to extract oil in the seeds. Take soya for example: cleaning→ crumble→ soften(steam conditioning)→ flaking→ extrusion→ solvent extraction→ evaporation→ steam stripping→ soya crude oil Ⅰ. Cleaning Raw material will mixed with some impurities in harvest, transport and storage. So after it goes into workshop should cleaning once time. Cleaning method as follows: 1. Screen: use sieve…
