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:
The present invention relates to a kind of production technique of soybean phospholipid, particularly a kind of preparation method with the acetone extraction powdered soy bean phosphatide.
Background technology:
The domestic and international at present soybean phospholipid extraction process that adopts, generally be the acetone extract oil that concentrating soya lecithin is added 2～3 times of volumes in the extraction mixing tank, re-extract 3～7 times does not have the soya-bean oil look to acetone, and the acetone of dissolving neutral oil reclaims the back repeated use through the distillation of retort decompression refrigerated condensation.Acetone insoluble matter then places vacuum and low temperature baking oven inner drying dehydration precipitation, and dried soybean phospholipid moisture content is powdered soy bean phosphatide less than 4 after the pulverizing.Chinese patent ZL90102531.1 " a kind of Processes and apparatus that extracts soybean phospholipid ", this patent is to add the petroleum ether and stirring dissolving with hydrated oil foot, extraction after filtration,, distillation, condensation, obtain mixing soya beans phosphatide after vacuumizing, all there is the discontinuity of production process in above production technique, material can not separate continuously, solvent loss is big, the steam consumption, the defective that water consumes, power consumption is big.
Summary of the invention:
The technical issues that need to address of the present invention are: the discontinuity of producing in the former technological process, situation such as material can not separate continuously, and solvent loss is big, and the product production that the steam consumption, water consumption, power consumption cause greatly is low, and the product yield is low.Technical scheme of the present invention is: the preparation method of powdered soy bean phosphatide, adopt acetone solvent through refining extracting and separating, the raw phospholipid of solid phase is further refining, pulverizing, behind low-temperature vacuum drying, make, it is characterized in that: the preparation method may further comprise the steps, and a. is added to the concentrating soya lecithin raw material in the single extraction stirred pot, and the acetone that adds 2～30 times of volumes is in jar, mix extraction 20～90 minutes under the normal temperature and pressure conditions, make concentrating soya lecithin fully be dissolved in the solvent; B. carry out solid-liquid separation through whizzer, liquid phase enters the mixing oil storage tank, and solid phase phosphatide carries out reextraction; C. reextraction adopted acetone extract 20～90 minutes; D. the mixed solution after reextraction finishes carries out secondary separation with whizzer; E. after separation finishes solid phase phosphatide is pulverized, liquid phase enters the mixing oil storage tank; F. dry 2～6 hours of the soybean phospholipid after will pulverizing (0.09～0.10mPa, 40～80 ℃) under vacuum heating conditions; G. the mixing oil in the mixing oil storage tank by solvent pump pump into that vaporizer carries out once, secondary, three evaporations, condensation, acetone solvent rectifying (60-120 ℃) is reclaimed.The preparation process of powdered soy bean phosphatide is carried out under the pipeline air-tight state, discharging continuously.This preparation method who provides now is airtight owing to entire operation process pipeline, discharging continuously, so output height, and the also more former technology of security is strong, and the purity and the quality of product are enhanced.Method with the refining soybean phospholipid of traditional domestic and international widely used production is compared, and the present invention has the following advantages:
(1). concentrating soya lecithin needs to extract repeatedly 3～7 times with acetone in the traditional processing technology, and the present invention only needs two
Inferior getting final product.
(2). it is bigger than traditional technology that the present invention adds quantity of solvent, but solvent loss is little.
(3). traditional processing technology is opened type, discontinuity production, and the present invention realizes the continuous closure of pipeline,
Discharging continuously.
(4). traditional processing technology is an opened type, and acetone belongs to combustible and explosive articles, and is dangerous big, to human body
Hazardness also big, acetone is in closed conduit after the existing process modification, safety coefficient improves.
(5). traditional processing technology labour intensity is big, therefore yields poorly, and labour intensity of the present invention is little, and output is carried
High.
(6). traditional processing technology is that deoiling, dewatering carries out simultaneously, utilizes CaCL
2Absorb moisture, therefore reclaim
CaCL is arranged in the oil
2Composition, this oil can not remake other purposes, and being first de-oiling, the present invention dewaters again,
Oil can be used as waste oil and handles.
(7). acetone reclaims by retort distillation condensation in the traditional processing technology, and the acetone moisture after the recovery is still
Height, between 0.3%～0.5%, and the present invention has rectifying to reclaim acetone, the acetone moisture after the recovery
Between 0.09%～0.2%, be enhanced.
(8). acetone insoluble matter is the precipitation that dewaters in the vacuum and low temperature baking oven in the traditional processing technology, to the matter of product
Amount and yield are influential, and the present invention then is cryodrying under vacuum condition, to the quality of product with
The yield influence is less, so the quality of product is greatly improved.
(9). owing to extract with circulation is efficient in closed conduit, material separates continuously, makes in the whole technological process
Molten consumption, the steam consumption, water consumption, power consumption all reduce many than traditional method.
(10). owing to be successional, can under 100,000 grades of purifications, make quality product reach pharmaceutical grade, domestic
Can production my one family of company only at present of enterprise of the refining soybean phospholipid of pharmaceutical grade.
