Description

TECHNICAL FIELD

[0001] The utility model belongs to oil filtering technical field, concretely relates to a kind of oil filtering device for frying multi-flavor peanut. BACKGROUND

[0002] The basic principle of oil filtering for frying multi-flavor peanut is to remove the impurities, residues and moisture in the oil by physical methods, so as to keep the oil clean and high quality. During the filtering process, filter screens or filtering media (such as stainless steel membranes) are usually used to block the passage of impurities and residues, while allowing the oil to flow freely. Under the action of gravity or pressure, the impurities and moisture in the oil are separated out, thereby achieving the purification of the oil. However, the coating of multi-flavor peanuts is composed of powder, which results in a high content of powder in the oil. This leads to the easy clogging of the aluminum membrane during filtering, which needs to be cleaned regularly. In particular, some filtering machines rely on a single filter cartridge, and if the filter cartridge is not replaced in time, the phenomenon of filter cartridge explosion may occur. SUMMARY

[0003] The utility model solves the technical problem of providing an oil filtering device for frying multi-flavor peanuts, which is simple in structure, convenient and practical. The coarse filtering is performed by the stainless steel filter screen cover, so that the larger impurities are filtered out in advance, and the coarse filtering residue is prevented from adhering to the filter, thereby affecting the filtering efficiency.

A plurality of oil outlet joints are connected to the side wall of the filter tank and connected to the corresponding filtering devices through the connecting hose. One end of the reflux pipe is connected to the oil inlet joint. A reflux pump is connected to the reflux pipe.

[0005] Preferably, the filtering device includes a disc-type filter shell, bolts, fine filter cartridges, a lead-out joint and a connecting pipe.
