[0020] Please see Figures 1 to 5 An edible oil pressing and refining device, wherein the oil outlet groove 2 of the screw press 1 is inclined downward toward the side where the oil collection tank 8 is located, so that the pressed oil will flow obliquely downward toward the oil collection tank 8 along the oil outlet groove 2, and the oil collection tank 8 is located below the end of the oil outlet groove 2.

[0021] Please see Figure 1 , Figure 5 A filter cylinder 7 is provided at one end of the oil outlet groove 2 near the oil collection tank 8. The filter cylinder 7 is a hollow cylinder, with one end connected to the oil outlet groove 2 and the other end closed. The filter cylinder 7 is covered with filter holes. The number, distribution, and size of the filter holes can refer to existing technology, as long as they can effectively filter out impurities from the grease. The grease flows into the filter cylinder 7 along the oil outlet groove 2, and after being filtered by the filter cylinder 7, it falls into the oil collection tank 8.

[0022] Please see Figure 5The central axis of the filter cylinder 7 is parallel to the direction of the oil outlet groove 2. A first hydraulic cylinder 9 is installed at the oil outlet groove 2.

A baffle 11 is provided at the upper end of the cylinder body of the first hydraulic cylinder 9. The baffle 11 is also inclined downward towards the side where the oil collection tank 8 is located to prevent a large amount of grease from flowing onto the first hydraulic cylinder 9. The grease squeezed out by the screw press 1 will first flow onto the baffle 11, then flow along the baffle 11 to the oil outlet groove 2, then flow into the filter cylinder 7, and finally fall into the oil collection tank 8 after being filtered out. In one embodiment, the baffle 11 is arranged in a direction parallel to the oil outlet groove 2, which makes the structure more reasonable.

[0023] Please see Figure 1 , Figure 5 In one embodiment, the filter cylinder 7 is detachably connected to the oil outlet groove 2 via a threaded connection. This configuration allows the filter cylinder 7 to be removed for cleaning after a period of use, thus maintaining its filtration effect.

The threaded groove 6 is provided with an internal thread that matches the external thread. The filter cylinder 7 can be screwed into or out of the threaded groove 6 through the external thread. With this configuration, the filter cylinder 7 can be removed or installed by screwing, which is more convenient.

[0025] Please see Figure 2 , Figure 5 In one embodiment, the oil outlet groove 2 mainly consists of a groove body 3 and a mounting plate 4. The mounting plate 4 is detachably connected to the groove body 3. The cylinder body of the first hydraulic cylinder 9 is mounted on the mounting plate 4 and can be removed along with the mounting plate 4. This arrangement facilitates the maintenance and cleaning of the first hydraulic cylinder 9. Furthermore, the groove body 3 is provided with multiple threaded holes, and the mounting plate 4 is correspondingly provided with multiple through holes. Each through hole corresponds to one threaded hole, and a bolt 5 is provided that can pass through the through hole and be screwed into or out of the threaded hole, thereby realizing the detachability of the mounting plate 4.
