Description

Technical Field

[0001] The utility model relates to the technical field of oil processing, in particular to an extractor circulation spraying device with an online cleaning function. Background Art

[0002] Soy protein concentrate is made from soybean meal. After screening, extraction, desolventizing, drying and other processing techniques, the alcohol-soluble sugars and other non-protein components in the soybeans (mainly soluble sugars, ash, alcohol-soluble proteins and various odor substances, etc.) are removed. The resulting soy protein product contains more than 65% (dry basis) protein (N×6.25) and can be used to prepare food additives and nutritional supplements.

[0003] The extraction process uses the principle of extraction, selects an alcohol solution that can dissolve the alcohol-soluble substances in soybean meal, and makes the alcohol solution contact with soybean meal by soaking or spraying, so as to remove the alcohol-soluble substances in soybean meal and increase the protein content of soybean meal. At present, the soybean protein processing industry generally uses extractors to extract soybean meal. During the multi-stage extraction of soybean meal, when the flow rate of the mixed liquid slows down, the sugars and other substances in the mixed liquid will be deposited on the wall of the spray pipeline, resulting in a reduction in the diameter of the spray pipeline. In severe cases, it will cause the spray pipeline to be blocked, which is not conducive to the stable and continuous production of soybean concentrated protein.

[0004] The patent with application number 202120150086.1 discloses an extractor spray pipe, which is provided with a first pipe section, a second pipe section and a third pipe section which are connected end to end and have decreasing diameters successively, and the oil inlet end of the first pipe section is connected to a circulating oil pump through a pipeline. At the same time, multiple spray holes are evenly opened on the three pipe walls. The blockage of the spray pipeline is alleviated by increasing the flow velocity and pressure of the tail section and increasing the flow rate of the mixed liquid. Although this method can reduce the formation of sediment in the spray pipeline to a certain extent, it is not conducive to regulating the flow velocity of the mixed liquid in the spray pipeline, and it is impossible to remove the sediment in the spray pipeline from the root.
