This project makes use of Condensed Soybean Phospholipids(CSP)to produce highly pure powdered soybean lecithin.In the production technology,the first step is to de-oil by continuously delivered material,high effective mixing CSP with acetone and circular extraction.The second step is to centrifugally separate the lecithin miscellaneous liquid into miscellaneous oil and solid-state lecithin with acetone.Then the mixing oil can be separated into crude oil and acetone by vaporization and condensation.If the acetone contains too much water,it shoud be rectified for use circularly.Solid state lecithin with acetone can be made into highly pure powdered soybean lecithin (acetone insoluble matter >95%)under the following conditions:vacuum 750mmHg,temperature 60℃,time 20 minutes.The production not only reaches the domestic and oversea quality index,but also has favorable hydrophilic property,which makes it become natural food additive and sanitarian nurture.
