(1), the peanut is a kind of high oil content crop, its internal grease to globular or granular exists in cells surrounded by a closed layer of film, in the process of is being squeezed from the outside world, the membrane and cell wall is broken, and peanut oil issue from the crack.In extrusion process, part of peanut oil, peanut become brittle and hard, lost the original elasticity;And peanut red fiber is more, after the pressure, and peanut surface separation, thus make the peanut red easy to fall off;I palm oil refinery plantﾧn the extrusion process, the peanut is under pressure rather than the shear stress, so no nibs phenomenon, it is easy to recover;
(2), penguin press according to the requirement of the fat content in use process, different pressure respectively.Different skim peanut effect can be obtained.
Technical requirements: peanut degreasing rate more than 50%;Full no pieces in peanuts, peanut, no adhesion phenomenon between peanut red fall off easily.Important factors affect the degreasing effect is water, secondary factor is time, to reach the best degreasing effect conditions is 4.52% - 7.26%, (water paint affect yield efficiency, moisture dry easily cause Watson breakage rate is too high.
Peanut oil draught fanﾧ
Peanut kernel temperature control pressure drying raw material package
4, the conclusion
In peanut oil mill has a certain pressure, a certain amount of moisture, temperature and time of the effective conditions, using the hydraulic oil press squeeze peanut kernel, oil mill boiled oil can get apricot yellow color, flavor, fragrance, taste pure peanut oil and degreasing effect different peanuts;
