Corn Oil Press

The size of the screw press and the oil discharge line of the corn oil press has been optimized, and the oil yield is high, the oil output is large, the slag leakage is small, and the extrusion is clean. After the crude oil is filtered by centrifuge, the oil is golden and bright, fragrant, green and pure natural, which is the ideal product for the upgrading of new oil mill.

In the corn oil press, the oil extraction process can be divided into three stages, namely, the feed (pre-pressing) section, the main press section (oil extraction section), and the cake section (heavy oil leaching section). 1) Feed section: the press begins to be squeezed tight in the feed section, discharge air and a small amount of water, plastic deformation occurs to form a "muffin", and begin to produce oil. The high oil content starts to produce oil at the feed compression stage. It should be noted that back pressure is easy to occur in the feed section, and measures of forced feeding and pre-pressing should be taken to overcome "back feed".

Main press section: This stage is the stage of high pressure mass oil discharge. At this time, due to the rapid and regular reduction of the space volume of the press chamber, the press material is strongly squeezed, the material begins to combine, the press material becomes a continuous porous material in the press chamber and is no longer loose, and a large amount of grease is discharged. At the same time, the press material will also cause the material layer velocity difference displacement, fracture, mixing and other phenomena due to the screw break, the squeezing force of the press chamber and the shear action of the press cage Angle, so that the oil circuit continues to open. It helps to drain oil quickly.

Corn oil press features: large capacity, high pressure, more oil, short pressing time, simple operation. Small footprint, low power consumption, small wear, solid frame structure, long service life; The oil extracted from the press has strong fragrance, good taste, clean and clear impurities, and full nutritional composition.
