Sunflower phospholipid technical scheme
I. Introduction
Sunflower oil, oil mill or sunflower oil leaching plant produced sunflower wool oil, in order to extract sunflower lecithin, increase business efficiency. In sunflower oil refining process, the water absorption of phospholipids, phospholipid will in hydrated form from crude oil separated by phospholipids and boiling water, evaporation dehydration, can get the sunflower lecithin. The use of lecithin, soluble in ethanol, and other properties of phospholipids, insoluble in ethanol, the extraction of lecithin from lecithin; then the oil and fatty acid soluble in acetone, insoluble in acetone and properties of lecithin, the lecithin in oil and fatty acid separation, finally preparing sunflower lecithin, sunflower lecithin is a senior nutrition, its nature is better than that of soybean lecithin.
Lecithin production needs equipment including water pot, centrifuge, scraper film evaporator, extractor, centrifuge, cooler, evaporator, distillation equipment etc..
Zhengzhou Dayang Oil Chemical Equipment Co., Ltd. produces sunflower lecithin equipment, sunflower oil lecithin machine.
