Three important steps to oil press extraction equipment?

Oil press extraction equipment

Press equipment oil press process can be divided into three stages, namely the feed (pre-press) segment, the main press (oil) segment, into the cake (weight and drain) segment:
(1) Feed section in oil press extraction
Virgin material in the feed section to move forward at the same time, began to be a tight squeeze effect, so that the exhaust air and a small amount of water to form a "muffin", and then plastic deformation, began out of oil.

(2) The main press section in oil press extraction
This is a lot of high-pressure oil discharge phase. Since then pressing the space quickly bore regularly reduced so virgin material particles begin to coalesce, virgin material in the virgin bore a continuous porous material is no longer loose. Virgin material particles in the compressed oil at the same time, also because of the spiral interrupted, pressing bore resistance, squeeze cage shearing edges, causing the material layer speed difference displaced fracture, mixing and other phenomena, so that the oil continue to be open, there is conducive to the rapid drain grease.

(3) Into the cake segment in oil press extraction
In the segment to the cake, pressing the material to form a press cake has become a complete plastic body, then pressing the material almost integrally move forward, resulting in greater resistance to compression, then the higher pressure in favor of pressing resid feed further leaching.
