Description

TECHNICAL FIELD

[0001] The application relates to the technical field of lard production, in particular to a lard residue liquid impurity filtering device. BACKGROUND

[0002] Lard, also known as pork oil or pork fat, is one of edible oils extracted from pork. The initial state is a slightly yellow translucent liquid edible oil, which is white or light yellow solid at room temperature. Lard residue is the solid hard block left after the extraction of lard from the fat tissue in pork by melting and refining. A filtering device is needed to filter the lard residue during lard production.

[0003] Patent No. CN221014953U discloses a lard residue liquid impurity filtering device. The lard residue liquid impurity filtering device filters the impurities in the lard residue liquid more carefully through a degreasing cotton layer, avoiding the situation that the holes are blocked by impurities and the small impurities pass through the holes when a filtering plate with smaller holes is used. However, the device does not have related equipment to keep the internal temperature of the filtering device constant, which will cause the oil liquid remaining in the degreasing cotton layer attached to the inside of the filtering device to solidify at room temperature, blocking the filtration of the oil liquid, reducing the usable times of the degreasing cotton layer, and needing to replace it frequently, shortening the service life of the filtering device, increasing the lard filtering cost, and causing waste of lard.
