The working principle is as follows: in the frying process, the first vent hole 73, the second vent hole 71 and the second oil outlet 75 are closed, and the frying oil in the oil storage tank flows into the filtering container through the first oil inlet 72 in the frying process, flows through the filter screen 11 and then flows out from the first oil outlet 74, so that the frying oil is continuously filtered circularly, the whole production process is ensured to be carried out smoothly, and the higher clarity of the frying oil is kept;
in the process of recovering the oil attached to the filtered food scraps, the first oil inlet 72 and the first oil outlet 74 are closed, the first vent 73 is opened, the filtering container is in a negative pressure state under the action of the vacuum pump 8, then the second vent 71 and the second oil outlet 75 are opened, and the frying oil attached to the food scraps instantaneously breaks away from the food scraps and is gathered at the bottom of the filtering container under the action of pressure difference, and flows into the recovering container 9 through the second oil outlet 75 and the recovering pipeline 3. When the food scraps accumulated in the filter screen 11 are to be removed, the locking device 16 is released, the cover 6 on the container body 7 is opened, the filter screen 11 is manually taken out and the food scraps thereon are shaken off, and simultaneously, the first filter screen 12 or the second filter screen can be manually taken out and the food scraps thereon are shaken off.
The present invention has been described above by way of example, but the present invention is not limited to the above-described specific embodiments, and any modification or variation made based on the present invention is within the scope of the present invention as claimed.
