Take the basic process of squeezing oil. In the screw press oil press factory in Henan, press to take the oil process can be divided into three stages, namely the feed (pre-press) segment, the main press section (the oil section), into the cake segment (weight and drain section ). Feed section: virgin material in the feed section began squeezed tight, exhaust air and a small amount of water, plastic deformation to form a "muffin", and start the oil. High oil and fuel in the compression phase begins feed oil. Note that easy to produce a back pressure in the feed zone, should take measures to force feeding and pre-press molding of Henan press, to overcome the "back feed." Main press section: This stage is the formation of a large number of high-pressure oil discharge stage. Since then pressing bore space quickly on a regular basis to reduce the volume, pressing strongly squeezed Henan press material prices began to combine between the pellets, pressed virgin material in the bore of a continuous porous material rather loose, a large oil discharge at the same time, pressing the material but also because of the spiral interrupted, pressing bore scraping force, pressing cage angular shearing caused by the material layer speed difference displacement, fracture, mixing phenomenon, so the oil continues to open, conducive to the rapid drain grease . Into the cake segment: virgin material in the segment has been formed into a cake-watt massive cake, was almost the whole propulsion, and thus have a greater resistance to compression press Henan brand, this time the tile is no longer pie compressibility large, but still maintain a high pressure in order to drain the oil without being sucked back. Finally discharged from the shoe press cake, the phenomenon will increase in size due to the elastic expansion effect appears. Working process of the power screw press, in a nutshell, is due role in promoting the rotating screw shaft in extra virgin bore, so pressing material continuously move forward, and because shortening and root screw shaft pressing screw pitch circle diameter increases, and decreases pressing bore diameter, so pressing bore ever-shrinking space and to produce virgin material crushing effect. Virgin material is compressed, the oil squeezed out from the cracks in the squeeze cage, while virgin material was pressed into a cake is discharged from the end of extra virgin bore.
