The Principle Of The Oil Press

(1), Peanuts are a crop with high oil content, its internal oil is in the form of spherical or granular in the cell surrounded by a closed film, in the process of being squeezed by the outside world, this layer of film and cell wall together rupture, peanut oil will flow out of the crack; During the extrusion process, the grease part of the peanut is extruded, and the peanut becomes brittle and hard, losing its original elasticity; The peanut red coat contains more fibers, and after applying pressure, it is separated from the surface of the peanut, so that the peanut red coat is easy to fall off; In the extrusion process, the peanuts are subjected to pressure rather than shear force, so there is no broken kernel phenomenon, and it is easy to return to its original state;

(2) According to the requirements of fat content, different pressures are applied. You can get degreasing peanut rice with different effects.
