Before oil extraction, screen is used to remove impurities. Oil extraction methods include hot pressing and cold pressing. 1.Hot Pressing Technological process: soybean-cleaning-fraction(Roughing)-soften-flaking-cooking-pressing Operating instructions:First, with 12 mesh / inch screen screen cleaning, make the impurities content is less than 0.1%, and then put it into the crusher, crushing degree of 2-4 flap, then softening, reduce the water content of soybean at around 15%, the softening time of 40-50 minutes, now flaking. There are two points in the role of the embryo: First, the destruction of cell tissue so that oil flow from the cell easily, Second is the grain of the seed oil rolled into a sheet, the surface area increases, thereby increasing the oil area, and greatly shorten the distance away from the...
