[0002] In the kitchens of homes, restaurants, and canteens, washing vegetables, scrubbing pots, frying food, and leaving leftovers will generate a large amount of waste oil. When this waste oil is discharged directly into the sewer, it will cause serious pollution. Now that the waste oil generated in the kitchen can be used as a raw material for the production of biodiesel, the recycling of kitchen waste oil will also have great prospects. If the kitchen waste oil cannot be effectively recycled, it will cause a great waste of resources and environmental pollution.

[0003] Those skilled in the art have conducted research and improvements on this, such as a waste oil recycling residue filtering and processing device with application number CN202222502436.3.
