The Working Principle And Characteristics Of Oil Extrusion Machine
Time:Fri-12-21 hits:
The oil extruder is mainly used for the pre-treatment of rapeseed, corn germ and other high-oil-bearing materials before the leaching and the treatment before the leaching of various pre-pressed cakes.
Among them, the pretreatment section of the rice bran oil production line especially needs this equipment, which can increase the oil yield, improve the quality of the oil, and reduce the loss of equipment.
The puffing principle of the oil extrusion puffing machine:
Utilizing the effects of unequal-distance spiral extrusion, friction, shearing, etc., the mechanical energy is converted into heat energy, and a certain pressure and temperature are formed in the expansion cavity, so that the material is ejected and expanded through the discharge die.
Features:
1. Puffed rice bran and other low-oil crops can be kept fresh for more than two months, the production capacity of the extractor is increased by 30-45%, the residual oil of the dry meal is less than 1%, and the protein content and color of the bran meal are better than the granulating drying leaching.
Expanded soybeans can deodorize and inactivate urease, the production capacity of the extractor is increased by 45-50%, the residual oil of the dry meal is less than 0.8%, and the protein content and color of the soybean meal are better than the drying leaching.
2. Puffing and pressing of high-oil crops: After adding a squeezing cage, it can be used for squeezing and puffing high-oil crops (more than 30% oil), and then directly sent to the press (high oil content needs to be dried and then sent) .
The extruded material is in the form of paste/sponge, and the output of the press is increased by 0.5-3 times. The quality of the oil is the original color, similar to cold-pressed oil.
