This machine is mainly composed of five parts: the electric control part, the heating and pressing part, the adjusting part, the transmission part and the vacuum filter oil.
The power bolt after reducing is transmitted to the spindle speed. The screw press is mounted to the spindle with rotation. The oil in the threads will continue to move forward, because the space between the press bore and screw gradually reduced, the oil density increase, thus the pressure increases gradually, in the process of squeezing, oil particle, the friction between the oil and the parts, the heat generated, so as to form oil extracting pressure, temperature of two elements, destroy the oil organization cell structure, the oil overflows from the oil line, the cake will be launched from the cake mouth, when the spilled oil flows through the oil filter on the oil cylinder,   the vacuum pump extracts the air inside the barrel and the negative pressure formed in the barrel, the oil is drawn through the filter cloth and pumped outside the barrel, and the oil sludge will be quarantined on the cloth, then obtain the pure oil.
