Abstract
A process for squeezing the soy dregs to obtain soybean oil includes drying the soy dregs generated by preparing soy sauce from soybean and wheat flour, adding fibrous powder, stirring, puffing, squeezing to obtain soybean oil, cooling and breaking.
Description
The present invention relates to a kind of oil expression method of soy sauce slag.
At present, raw materials such as soy sauce station-service soya bean, flour, salt ferment, and produce soy sauce product and soy sauce slag byproduct.The soy sauce slag is directly used in till the land fertilizer or be used to the feed of breeding fish on a small quantity of peasant basically, but because its salt concentration is about 25～35%, and oil-containing is about 10～20%, can make the soil salinization, make fish death, has a strong impact on water quality again, environmental protection.Simultaneously, little, middle chicken feed request oleaginousness is about 1～2%, and saltwater fish feed request oleaginousness is about 20～30%, and feed of grass carp requires not oil-containing, so the soy sauce slag can not be directly used in feed, can not prepare all feeds on demand.At present, the soy sauce slag is essentially refuse, and existing oil expression method can not be pressed the soya-bean oil in the soy sauce slag again.People thirst for obtaining the soy sauce slag is directly pressed the method for removing soya-bean oil for a long time, make the soy sauce slag can become the feedstuff raw material that adds on demand.
The oil expression method that the purpose of this invention is to provide a kind of soy sauce slag, it can directly press the soy sauce slag and remove soya-bean oil, and utilization of waste material is profitable.
The present invention is achieved by following technical proposals: the oil expression method of soy sauce slag, comprise wet soy sauce slag drying, auxiliary material, stirring, expanded, oil expression, cooling, pulverize, it is characterized in that: adding weight percent at exsiccant soy sauce slag is 10～45% cellulosic powdery auxiliary material, be stirred to uniform mixing then, at about 10～30kg/cm
2Extruding puffing under the pressure extracts oil again, is cooled to envrionment temperature.
The present invention is owing to be used in rationally and simply dry, auxiliary material, stirring, expanded, oil press process, have that technology is simple, oil expression efficient height, cost are low, utilization of waste material, environmental protection, for fodder industry provides new cheap raw material, the advantage of social and economic benefits and good.
Fig. 1 is the oil expression method technological process block-diagram of soy sauce slag of the present invention.
The invention will be further described below in conjunction with embodiment.
As Fig. 1, foreign material in the wet soy sauce slag are removed, dry in about 120～500 ℃ of hot air dryers afterwards, optimum moisture content is 3～8%.Adding weight percent through impurity elimination exsiccant soy sauce slag on proportioning machine is about 30% animal meat bone, fish meal or animal and plant fiber matter powdery auxiliary materials such as cavings, wheat shell, makes soy sauce slag frictional force and nutrition increase such as calcareous; The mixing that stirs on stirrer then is at the about 20kg/cm of pressure
2Extrusion machine in extruding puffing, reach and be heated to about 110 ℃, softening and increase the purpose of frictional force, the green soy bean oil and squeeze out sheet soy sauce slag bran of on screw oil expeller, squeezing out respectively again.Sheet soy sauce slag bran is cooled to envrionment temperature, pulverize into about 20～60 order powdery soy sauce slag bran powder through pulverizer, it contains rich in protein, starch, amino acid, nutrition such as calcareous, can be used for preparing chicken, duck, goose, pig, fish meal, 2000 yuan of Renminbi per ton approximately.The green soy bean oil cooling can be used for feed or technical oils to envrionment temperature, 4000～5000 yuan of Renminbi per ton approximately, and also refining is senior soya-bean oil again.The oil yield that makes green soy bean oil by above-mentioned processing method is about 15～30%.
Claims (4)
1, a kind of oil expression method of soy sauce slag, comprise wet soy sauce slag drying, auxiliary material, stirring, expanded, oil expression, cooling, pulverize, it is characterized in that: adding weight percent at exsiccant soy sauce slag is 10～45% cellulosic powdery auxiliary material, is stirred to uniform mixing then, at about 10～30kg/cm
2Extruding puffing under the pressure extracts oil again, is cooled to envrionment temperature.
2, according to the oil expression method of the described soy sauce slag of claim 1, it is characterized in that: this cellulosic powdery auxiliary material is animal meat bone, fish meal or plant fiber powder, and its weight percent that accounts for gross weight is about 30%.
