After the citrus is lifted to the leveling device by the elevator, it falls evenly into the oil grinding area. The stainless steel acupuncture nets in the oil grinding area rotate relatively in groups. The oil cells of the citrus are punctured under the action of acupuncture, and the citrus oil flows out. The upper part of the roller is equipped with a stainless steel scraper to push the citrus to the discharge port evenly and at low speed. The whole machine is equipped with high-pressure water jets to quickly separate the oil from the surface of the fruit. The separated oil and water flow into the lower juice hopper and enter the next process for processing. This equipment is also suitable for extracting oil from navel oranges, lemons, grapefruits and other fruits.
