This article is only an overview of production processes, detailed information, please enter the double spike machinery official website: www.ssyzjx.com leaching equipment, oil extraction equipment, solvent extraction projects, "the 4th solvent extraction project" is a new oil extraction technology , not only for our plant protein factory of high quality raw materials, but also for valuable shelf oil extraction provides a new way. Specifically for the extraction of valuable functional oils, such as walnut extract, grape seed, corn germ, microbes, pigments and other lipid products. Has been widely used in oil, chemical, pharmaceutical, food and other industries. The fourth main component of the solvent is liquefied butane and propane. The boiling point of the solvent component is mostly below 0 ℃, wherein propane boiling point -42.07 ℃, butane boiling point of -0.5 ℃, is a gas at normal temperature and pressure, as pressurized liquid. The basic principle of this process is: at room temperature and a certain pressure (0.3MPa ~ 0.8MPa), with a fourth countercurrent solvent extraction of oil feed embryos (eg walnuts, evening primrose seeds, etc.), then mix in the oil and meal The solvent vaporized under reduced pressure, the solvent gas gasified and then through the compressor compression cycle using condensed and liquefied.
