A method for refining sesame oil according to claim 4, characterized in that: The steps include: Step 1: Put the sesame oil raw material to be processed into the hopper (101), and adjust the material distribution valve plate (102) according to the workload to allow the sesame oil raw material to be introduced into the feed channel (104); Step 2: Turn on the motor (205), the motor (205) drives the connecting shaft (213) and the pressing screw (212) to rotate, and one end of the pressing screw (212) rolls up the sesame oil raw material and continuously squeezes and presses it; Step 3: During the squeezing process, the air pressure inside the squeezing chamber (207) is adjusted through the air pressure valve (210), and high-pressure air is injected through the vacuum pump (201) and the compressor (202). The high-pressure air is used in conjunction with a plurality of air guide pipes (211) to simultaneously pressurize the inside of the squeezing chamber (207), thereby improving squeezing efficiency; Step 4: After pressing, the crude oil is introduced to the top of the oil guide plate (208) through the oil guide port (209), and flows through the oil guide plate (208) to the inside of the oil feed tank (302) for refining; Step 5: The crude oil flows into the high-density filter (303) after passing through the oil feed tank (302), and is filtered by the high-density filter (303), so that the crude oil is filtered and enters the lower part of the refining box (3); Step 6: The refined sesame oil is introduced into the essential oil storage box (4) for storage through an oil pump, the sealing valve is opened, and the waste material inside the pressing cavity (207) is introduced into the waste material tank (304), and the waste material is filtered out through the coarse material filter (305) for centralized treatment.
