[0002] Safflower rapeseed oil is known to have a high content of linoleic acid among vegetable oils. Linoleic acid is the most important unsaturated fatty acid in the human body. It has the effect of preventing cardiovascular and cerebrovascular diseases, fatty liver and other metabolic diseases. In terms of meeting the dietary goals recommended by many health associations, the fatty acid composition of rapeseed oil is consistent with its use as a substitute for SFA: the average diet contains about 30% of calories as fat, composed of less than 10% SFAs, 8-10% PUFAs, and the ratio of linoleic acid to linolenic acid is 4:1 to 10:1, and the rest is monounsaturated fatty acids. In the manufacturing process of rapeseed oil, it needs to be pressed and filtered.

[0043] Specifically, the top of the pressing box body 1 is connected to a rotating toothed disc 2 and a main gear 201 through a bearing, and the rotating toothed disc 2 and the main gear 201 are meshingly connected. A motor 202 is fixedly installed on the top of the pressing box body 1, and the output end of the motor 202 is fixedly connected to the shaft of the main gear 201. A lifting screw 3 is threadedly connected to the middle part of the rotating toothed disc 2, and the bottom of the lifting screw 3 is fixedly connected to the pressing plate 301.

[0044] By adopting the above scheme, the starting motor 202 can drive the rotating toothed disc 2 to rotate through the main gear 201, and then drive the lifting screw 3 and the pressing plate 301 to move up and down, thereby facilitating the full pressing of the rapeseed raw material located on the supporting filter plate 6.

The scraping plate 703 scrapes the lower surface of the supporting filter plate 6 to prevent rapeseed oil from remaining, so that the rapeseed oil can flow into the oil collection bin 102 more smoothly. When the scraping rod 7 rotates, the rolling rod 8 is driven to rotate through the driven wheel 804, and the rolling roller 802 is driven to rotate to roll the residue on the arc filter plate 9. The rapeseed oil remaining in the residue is rolled out and discharged into the bottom of the slag discharge bin 103.
