One, clean up The raw rapeseed is sieved with a vibrating screen to remove large and small impurities. The impurity content in the material should not exceed 0.5%, and it is necessary to strictly prevent the iron impurities in the material from entering the oil press. Two, broken skin Use a small roller mill for rolling to break the rapeseeds. It is required that the skin will not fall off or be crushed, and it will be "smiling", and the peeling rate should not be less than 85%; the powder degree should not exceed 5%, the feeding should be uniform during the operation, the flow rate should be appropriate, and the distance between the rollers should be adjusted properly . Three, add water Put the rapeseed material into the pan, add some hot water while stirring, and add the water to the 13%-15% of the water content in the material. Four, stir-fry The equipment in the oil press plant mostly uses a flat-bottomed pan (you can also use a cylindrical seed frying pan, which has good effect). The final temperature of the frying material is 120℃-132℃. The clinker will not leak oil, elastic, and loose when you let it go. , The maturity is even and not sandwiched. The residual moisture of the clinker after frying is about 2%. At the same time, ensure that the temperature of the material entering the oil press is 120℃-125℃. Five, squeeze After the press chamber is preheated normally, the clinker can be put into formally, and the cake thickness can be adjusted to 1.25-2.5 mm. Whether the squeezing effect is good or bad, it can be randomly determined whether the stir-frying is qualified. Therefore, the pressing operation must be observed, inspected, and adjusted frequently. In order to maximize the oil yield of the press, the pressed cake should be adjusted to be thinner, but it is required that no green smoke or burnt is emitted from the cake, and the residual oil of the dry cake is controlled between 5% and 6%. Six, crude oil treatment The squeezed crude oil enters the oil pool and is first precipitated to remove solid impurities. If further impurity removal is required, a filter is required to obtain clean oil. Disclaimer: Some articles on this website are transferred from the Internet.
