When corn is used as raw material to produce corn mash, corn starch or cornstarch sugar, approximately 8% to 12% of corn germ can be recovered, and can be used to obtain corn germ oil. Corn germ oil can not only be refined into nutritious edible oils and fats such as salad oil, cooking oil and margarine, but also can be used in pigments, paints and soap making industries. The deoiled cake contains nutrients rich in protein and can be used as a nutritional supplement for a variety of foods. Preparation of oil from corn germ must be cleaned, dried, softened, embossed, steamed and fried, oiled, and refined. ? 1. The corn germ recovered from corn mash was cleaned up and mixed with more corn flour and dander, which needed to be cleaned with a double shaker. Mesh screen mesh, the first layer to remove large impurities, with a 1? 5 mesh sieve; second layer of corn powder, crushed leeches and dander, with 4 mesh sieve. If there are still more embryos in the sieve, you can use a 5 or 7 mesh sieve to reduce the loss of corn germ. The corn germ recovered from corn starch is mixed with impurities such as dander and radicle sheath, and it needs to be rinsed several times in clean water with a shallow dish or a gutter. Plants equipped with cyclone separators can use the centrifugal effect of swirling to separate germs. ? 2. After the dried and recovered corn germs are cleaned, they contain high moisture, and the enzyme activity is strong and easily contaminated by microorganisms, which easily leads to deterioration and rancidity of the oil. In order to maintain the freshness of corn germ during storage and transportation, the cleaned corn embryos must be dried or dried to a moisture content of 10% or less. ? Third, softening and softening commonly used hot air dryer or hot steam drum dryer, so that when the heat treatment of corn germ, the moisture content dropped to 10% or less, and make the material embryo plasticity changes. Embryos should not be eagerly subjected to high temperature treatment when they are softened to prevent premature protein denaturation, so that the embryos lose their elasticity and affect embryo rolling, steaming, and oil extraction. ? Fourth, after the embryos of embryos that have been embroiled are softened, they are rolled into 0.3-0.4 mm slices with a roller mill, and the cell structure is destroyed. This facilitates steaming and pressing of the embryos. ? 5. The steamed and fried embryos are steamed into the steaming and frying apparatus for 40-50 minutes until the embryo temperature reaches 115-120°C, the moisture content is 2%-4%, and the embryo color is gradually changed to brown-red, and the aroma can be smelled (but It can be squeezed when it does not appear to burn. ? Six, press oil production more use spiral oil press, the model can be determined by the scale of production, the scale of the larger production plant, can choose to use the joint type 200 spiral oil press equipment. The machine is equipped with steaming and frying, continuous operation, and easy operation. The embryo is steamed and fried and the oil is squeezed out in one set of equipment. After steaming and frying, the material embryo can be directly pressed into the press to press oil. When pressing, the room temperature needs to be maintained at 30 4040° C., and the initial feeding is small. After the normal operation of the pressing machine, the material is uniformly fed, oiled and caked out. The normally operating press has an oil pressure of 8 revolutions per minute. The embryos were pressed for 2.5 minutes in the pressing process, and the thickness of the cake was 5-6 mm. The oil extraction rate of corn germ extracted during the production of corn mash was 22% to 26%, and the oil extraction rate of corn germ extracted during the preparation of starch was 25% to 28%, and the residual oil ratio in the pancake was 5%. ~6%. The prepared corn germ oil, commonly referred to as “hair oil†without refining, contains 0.3% of water and volatile matter, 0.2% of impurities, 6% of precipitates, yellowish color, and normal odor. "Hair oil" needs to be treated with hydration, alkali refining and deodorization to obtain high quality corn oil.
