Abstract

The present invention relates to the preparation process and is especially the preparation process of powdered soybean phosphatide. The preparation process includes the steps of: mixing concentrated soybean phosphatide material with acetone of 2-30 times volume and the first homogeneous extraction to make soybean phosphatide dissolve in the solvent; solid-liquid separation to make liquid phase enter mixed oil tank and solid phase phosphatide second extracted; extraction in the second extractor with acetone; the second separation of mixed liquid after the second extraction in centrifuge; powdering solid soybean phosphatide; vacuum heating to dry soybean phosphatide; and recovering mixed oil in mixed oil tank. The present invention is used in producing high-quality medical soybean phosphatide.

Description

Technical field: [0001] The invention relates to a production process of soybean lecithin, in particular to a preparation method for extracting powdery soybean lecithin with acetone. Background technique: [0002] At present, the soybean lecithin extraction process adopted at home and abroad is generally to add 2 to 3 times the volume of acetone extraction oil to the concentrated soybean lecithin in the extraction mixing tank, and repeat the extraction for 3 to 7 times until the acetone has no soybean oil color and dissolves the neutral oil. The acetone is recovered by decompression freezing, condensation and distillation in the distillation tank, and then reused. The acetone insoluble matter is placed in a vacuum low-temperature oven for drying, dehydration, and solvent removal. The moisture content of the dried soybean lecithin is less than 4, and the powdered soybean lecithin is obtained after crushing. Chinese patent ZL90102531.1 "A process and equipment for extracting ...
