Cottonseed oil press
    Cottonseed oil press is a machine for pressing cottonseed oil
    The main part of the cottonseed oil press is the press chamber, which is composed of a press cage and a spiral shaft rotating in the press cage. Its working process is to use the reduction of the spiral lead of the spiral shaft or the gradual increase of the diameter of the root circle.
    After the fried cottonseed material embryo enters the squeezing chamber of the cottonseed oil press, under the rotating action of the screw thread, the space volume of the squeezing chamber is continuously reduced and the squeezing effect is produced; the squeezed oil is squeezed out from the gap of the squeezing cage, and the residue is pressed into crumb like cakes, which are not squeezed from the end of the squeezing shaft Break off. Generally speaking, oil extraction by pressing can be divided into three stages: feeding (pre pressing) stage, main pressing (discharging) stage and cake forming (heavy pressing) stage. Gradually push the feed end towards the cake end. As the bottom diameter of the screw thread changes from small to large, the volume of each section in the press chamber is gradually reduced; and as the screw thread continuously pushes the blank into the press chamber, the product pressure is pushed forward and backward, the blank is compressed, and the oil is squeezed out. At the same time, adjust the cake gap to change the thickness of the cake. The smaller the gap is, the thinner the cake is, and the greater the pressure in the squeezing chamber is. In addition, the material embryo moves in the pressing chamber, causing friction between the material embryo and the strip row, the round row, the material embryo and the screw, the material embryo and the material embryo, and generating a large amount of heat, so that the temperature of the material embryo in the pressing chamber rises, which is favorable for the oil outflow in the material embryo and the oil production rate            
    The cottonseed oil produced by the cottonseed oil press needs to experience. The refined cottonseed oil is generally orange yellow or brown. The fatty acid contains 21.6-24.8% palmitic acid, 1.9-2.4% stearic acid, 0-0.1% arachidic acid, 18.0-30.7% oleic acid and 44.9-55.0% linoleic acid. The refined cottonseed oil can be used for human consumption. There are a lot of essential fatty acids in cottonseed oil, so it is best to mix with animal fat, because the content of linoleic acid in cottonseed oil is particularly high, which can effectively inhibit the rise of cholesterol in blood and maintain human health. The absorption rate of human body to cotton oil is 98%
