It also includes a conical filter plate 10. The upper and lower ends of the isolation shell 7 are provided with conical filter plates 10 for filtering oil residues. The filter apertures of the two conical filter plates 10 are different. The filter aperture of the upper conical filter plate 10 is larger than the filter aperture of the lower conical filter plate 10, so that the crushed animal fat blocks pass through the upper conical filter plate 10 into the isolation shell 7. It also includes a ball valve 21. The ball valve 21 is rotatably arranged on the discharge pipe 6. The angle of rotating the ball valve 21 can control the oil output size of the discharge pipe 6.

[0026] When it is necessary to refine the animal fat, the crushed animal fat blocks are injected into the upper shell 4 through the feed pipe 5, and the conical filter plate 10 filters the impurities carried in the crushed animal fat blocks, so that the impurities remain on the conical filter plate 10, thereby preventing the impurities from entering the isolation shell 7 and affecting the refining, thereby reducing the quality of the animal fat. The crushed animal fat blocks flow into the isolation shell 7. When the isolation shell 7 is filled with an appropriate amount of crushed animal fat blocks, the heater 9 is turned on, and the heating temperature and time of the heating tube 8 are adjusted according to the refining requirements. The heating tube 8 generates heat to refine the animal oil preliminarily boiled inside the isolation shell 7. After the crushed animal fat blocks are boiled for the set time, the ball valve 21 is turned to open the discharge pipe 6, and the refining passes through the lower conical filter plate 10, and then a secondary filtration is performed, so that the oil residue produced during the refining is filtered out, and the refined animal fat is discharged through the discharge pipe 6.

[0027] Example 2: Based on Example 1, please refer to Figure 1 and Figure 3, also includes a fixing frame 11, a driving motor 12, a stirring rod 14 and a bearing 13.

At the same time, the rotation of the stirring rod 14 can also separate the free fatty acids in the oil from the oil. It also includes a scraper 22. The scraper 22 is connected to the upper and lower ends of the stirring rod 14. The scraper 22 contacts the conical filter plate 10, and then the solidified grease on the conical filter plate 10 is scraped off.

[0028] When refining the crushed animal fat block, the drive motor 12 is turned on, and the output shaft of the drive motor 12 rotates to drive the bearing 13 to rotate, so that the bearing 13 drives the stirring rod 14 to rotate, and then the oil inside the isolation shell 7 is stirred, so that the oil is heated evenly.
