Soy Lecithin is hydration soybean oil as raw material quenched foot, bleaching, vacuum dehydration phospholipid concentrate production products. The product can be used as food additives or feed additives, but also as a raw material powder phospholipids or other phospholipids intensive products. The process uses multi-effect stainless steel rotary film evaporator, producing continuous, stable, and the resulting product is not oxidized phospholipids, do not break down, light color, good quality. Raw materials for the production of soy lecithin, soy should use good quality; oil pretreatment production should strictly clean up impurity, preferably peeling, puffing or heat treatment (ALCON process); leaching mixed oil production to be used vacuum evaporation and stripping, stripping and evaporation temperature as low as possible, generally no more than 110oC; unglued before leaching of hair oil, should be fine filter, in order to ensure quality indicators phospholipids.
