Description

Technical Field

[0001] The utility model belongs to the technical field of vegetable oil filtering equipment, and particularly relates to a residue filtering device for vegetable oil processing. Background Art

[0002] Vegetable oil is made from oil-rich plant kernels, such as peanuts, soybeans, and corn. After pre-processing, such as cleaning, shelling, crushing, softening, flaking, and extrusion, the raw materials are extracted through mechanical pressing or solvent extraction to obtain crude oil, which is then refined. During the production and processing of vegetable oil, most crude oils obtained through pressing contain a large amount of residue, which needs to be filtered out.

[0003] In the prior art, an oil filtering device is generally used to filter crude oil. For example, the invention with patent publication number CN109529436B discloses a vegetable oil oil residue removal device, which includes a filter barrel, an oil residue outlet is provided on the front side of the upper end of the barrel cavity; a lifting rod, a lifting rod is provided on each of the left and right sides of the upper end of the barrel cavity of the filter barrel, and a lifting rod is provided on the rear side of the upper end of the barrel cavity of the filter barrel and is distributed opposite to the oil residue outlet; the straight line where the oil residue outlet and the lifting rod on the rear side are located is perpendicular to the straight line where the lifting rods on the left and right sides are located; and a filter screen, which is movably placed on the upper part of the barrel cavity of the filter barrel; the filter screen is provided with a hinged seat under each lifting rod, and the lower end of each lifting rod is hinged to the hinged seat located below it, so that the filter screen can swing up and down around the lower ends of the left and right lifting rods.
