Description

Technical Field

[0001] This utility model relates to the field of animal fat processing technology, specifically to an animal fat filter residue cleaning mechanism. Background Technology

[0002] When processing animal fats, a leaf filter is used to filter out the residue. The tank of the leaf filter contains several rectangular filter plates arranged in parallel. The surface of the filter plates has several filter holes. Under the action of the oil pump, the animal fat is squeezed into the filter plates through the filter holes, while the residue in the animal fat is blocked and adheres to the surface of the filter plates, thus completing the filtration of the fat.

[0003] Excessive filter residue adhering to the filter surface can prevent animal fats from being forced into the filter through the filter holes, leading to excessive pressure in the tank of the leaf filter and causing the filter to be deformed and damaged. Therefore, it is necessary to clean the filter residue adhering to the surface of the filter regularly. Leaf filter tanks are usually equipped with an openable top cover. Cleaning the filter residue usually involves opening the top cover of the tank, then removing the filter from the tank and scraping it off. This disassembly process is complicated, inefficient, and can easily damage the filter by bumping it. Utility Model Content
