Filtering device and method for vegetable oil production

Abstract

The invention discloses a filtering device and method for vegetable oil production, and particularly relates to the field of vegetable oil filtration, the filtering device comprises a first main body mechanism, a second main body mechanism is arranged at the bottom of the first main body mechanism, and a filtering mechanism is fixedly mounted between the first main body mechanism and the second main body mechanism and comprises a filtering pipe; the outer wall of the filter pipe is in threaded connection with a sealing sleeve, a second filter plate is arranged in an inner cavity of the filter pipe, a plurality of second drainage holes are formed in the second filter plate in a penetrating mode, the second filter plate is arranged in a hollow state, second filter screens are inserted into an inner cavity of the second filter plate, a plurality of filter holes are formed in the second filter screens, and the number of the second filter screens is at least three. After multiple layers of second filter plates and second filter screens are arranged for layer-by-layer filtration, the first cleaning blocks and the second cleaning blocks are attached to the surfaces of the second filter plates to scrape filtered oil residues, so that the oil residues are prevented from blocking filter holes to influence the filtering speed.

Description

technical field [0001] The present invention relates to the technical field of vegetable oil filtration, and more particularly, to a filtration device and method for vegetable oil production. Background technique [0002] Vegetable oil is a compound formed by the reaction of higher fatty acids and glycerol. It is widely distributed in nature and is the oil obtained from plant fruits, seeds and germs, such as peanut oil, soybean oil, linseed oil, castor oil, rapeseed oil, etc. [0003] In order to obtain the oil with better quality and color, it is necessary to filter the vegetable oil. However, the device for filtering the vegetable oil in the prior art is inconvenient to clean the filter screen after filtering the oil residue impurities in time, thereby causing the filter screen plate. Blockage, which affects the filtration speed of vegetable oil and causes low filtration efficiency. SUMMARY OF THE INVENTION [0004] In order to overcome the above-mentioned defects of th...

Problems solved by technology

[0003] In order to obtain oil with better quality and luster, it is necessary to filter vegetable oil. However, the device for filtering vegetable oil in the prior art is not convenient for timely cleaning of the filter screen after filtering oil residue impurities, resulting in filter screen plate Blockage, which affects the filtration speed of vegetable oil and leads to low filtration efficiency
