Soybean oil crops are low, usually soybean oil content in the 11-20% range, the soybean oil press process is as follows:
1, Pressing: Soy - Cheongju Miscellaneous - Broken - Softening - flaking
Instructions: Soybean with size 12 mesh / inch mesh screening to the complex, so that the impurity content of less than 0.1%, then into the crushing, crushing degree of valve 2-4, and then softened to a moisture content in soybeans about 15%, the softening time 40-50 minutes, then flaking, flaking use two points: First, destroy tissue easily flow out of the oil from the cells, and second granular oilseeds rolled into thin sheets, surface area increases, increasing the area of oil, grease and greatly shorten the distance to leave blanks; steamed into the wok steamed fried, steamed soybeans Scoop moisture in the 1.5-2.8% range, the temperature to 100 That can begin to enter a press pressed to 110 degrees. Cake thickness control in about l-1.5 mm.
2, Cold-pressed: cold-pressed soybean whole seeds can be pressed, so that when the whole seed according to strict control of water, generally 8~10% of control, and note that according to the heating, the temperature rose to about 80 degrees before making news station.
Soybean moisture levels of the cold pressing method of manual inspection: incisors can bite cut bite molars flat shape and surface cracks, a slight noise is appropriate; if the flat shape, no cracks too wet, if a huge voice broke bite, it's too dry, you need to press the right amount of moisture before adjustment.
