Problems solved by technology

[0002] At present, belt conveyors are generally used for the transportation of soybean embryo flakes in my country. The belt conveyor consumes oil extraction time in the process of transporting soybean embryo flakes. The main methods for extracting oil from soybeans are pressing method, leaching method and water enzyme method, pressing method The oil extraction time of the leaching method and the leaching method are longer, and protein denaturation is caused in the process of oil extraction, which reduces the efficiency of the cake after oil extraction; while the amount of enzyme used in the water enzymatic method is relatively large, and cannot be reused. In order to overcome this shortcoming, the present invention The composite enzyme film is made into a film roller and fixed on a belt conveyor to perform solvent extraction and oil extraction on the pretreated soybean embryo flakes, which shortens the solvent extraction time and increases the number of cycles of immobilized enzymes

Abstract

The invention relates to a method and equipment for extracting soybean oil under the help of a composite enzyme membrane. When a belt conveyor is working, a belt is rotated under the driving of an electric roller, directions can be changed through a reversing roller, soybean embryo flakes are discharged through a guide chute, transported under the driving of the belt, and are subjected to crossed continuous rolling by an immobilized cellulase roll and an immobilized alkaline protease roll during transportation, the moisture humidity can be regulated under the environment of a vacuum container so as to achieve the optimum humidity in enzymolysis, the primarily processed soybean embryo flakes are overturned under the driving of the reversing roller and enter the next layer of belt conveyor, and are rolled through repeating the processes, and two layers are arranged. The preprocessed soybean embryo flakes are subjected to solvent leaching for extracting oil, so that the solvent leaching time can be shortened, and the circulation usage times of immobilized enzyme can be increased; the industrial production cost for extracting soybean oil can be lowered.
