COMBINED APPARATUS FOR PURIFYING VEGETABLE OILS Russian patent published in 2023 - IPC C11B3/02 C11B3/10 

FIELD: oil and fat industry.

SUBSTANCE: combined apparatus for purifying vegetable oils, characterized in that it includes two identically designed absorbers with a double-body housing, consisting of an upper adsorption chamber with a vertical shaft (6) or (31) and a lower filtration chamber located underneath it with a vertical shaft (7) or (32), which are installed coaxially, and on the shaft (6) or (31) in the upper adsorption chamber there is a combined frame-propeller mixer, and on the shaft (7) or (32) in the lower filtration chamber there is a combined frame-spiral mixer; on the top cover of the adsorption chamber there is a loading hopper with a dispenser-feeder for supplying the initial suspension into it, the lower bottom of the adsorption chamber is made conical, in the centre of it there is a conical solenoid valve installed with the ability to move in a vertical plane; in the lower part of the filtration chamber there is a combined filter partition, in the centre of which there is a cone solenoid valve installed with the ability to move in a vertical plane; in the side wall of the filtration chamber located above the filter baffle there is a pipe for supplying compressed carbon dioxide and a pipe for its removal; in the side wall of the filtration chamber located under the filter baffle there is a pipe for evacuation and a pipe for equalizing pressure; an intermediate storage tank and ribbon mixer are installed between the absorbers.

EFFECT: invention makes it possible to intensify the process of removing impurities from vegetable oils, as well as to obtain a finished product with high organoleptic and physicochemical properties and improved quality characteristics of the oil.
