[0002] The billet rolling mill is mainly composed of two or more rollers (high nickel-chromium-molybdenum alloy) rotating in opposite directions. When the oil material (soybean, peanut, cottonseed, etc.) passes through the middle of the two rollers, the billet is formed by the instantaneous extrusion force, and the crude oil is initially rolled out, and then the finished edible oil is formed through refining and leaching. It is a typical extrusion equipment, and the quality of the equipment directly affects the oil yield of the oil.

[0003] The embryo rolling mill is a key equipment in oil and fat processing.
