How to extract oil from groundnut?

Working principle of groundnut oil extraction machine: After the groundnut oil press decelerates, it will be transmitted to the main shaft. The pressing screw installed on the main shaft will rotate continuously to continuously push forward the oil between the threads. As the space between the squeezed tube and the pressed screw gradually increases Narrow, increasing the density of oil, so the pressure gradually increased. In the process of pressing, due to the automatic heat of the machine, by the automatic temperature control device, increase the temperature of the host body, thereby reducing labor intensity, abrasion of the peanut oil press body, labor, energy saving, time-saving, oil particles Between the friction between the fuel and the parts, resulting in heat. This constitutes the pressure of the oil extraction process, the two major elements of heat, destruction of oil tissue cells, oil spills from the oil line, the cake is from the cake head and the cake was launched between the mouth. When the overflow of oil through the oil pan into the oil filter above, the vacuum pump out of the barrel of air. The formation of negative pressure within the barrel, the oil through the filter cloth, was pumped into the barrel, and the residue was isolated in the filter cloth above, then get a pure oil.
