step three: in the squeezing process, the air pressure inside the squeezing cavity (207) is adjusted through an air pressure valve (210), high-pressure air is injected through a vacuum pump (201) and a compressor (202), and the inside of the squeezing cavity (207) is pressurized simultaneously through the cooperation of the high-pressure air and a plurality of air guide pipes (211), so that the squeezing efficiency is improved;

step four: after being pressed, crude oil is guided to the upper part of the oil guide plate (208) through the oil guide port (209) and flows to the inside of the oil feeding groove (302) through the oil guide plate (208) to carry out refining work;

step five: the crude oil flows into the high-density filter screen (303) after passing through the inside of the oil feeding groove (302), and is filtered by the high-density filter screen (303), so that the crude oil is filtered and enters the lower part of the inside of the refining box (3);

step six: refined sesame oil is led into an essential oil storage box (4) through an oil pump to be stored, a sealing valve is opened, waste materials in a squeezing cavity (207) are led into a waste material groove (304), the waste materials are filtered through a coarse material filter screen (305), and the waste materials are treated in a centralized mode.
