Description

Technical Field

[0001] This utility model relates to the field of phospholipid production technology, specifically to a stirring device for the production of modified phospholipids. Background Technology

[0002] Modified soybean lecithin is a chemically modified soybean lecithin product. Its preparation process usually involves hydroxylating natural soybean lecithin with chemicals such as hydrogen peroxide, benzoyl peroxide, lactic acid and sodium hydroxide, or hydrogen peroxide, acetic acid and sodium hydroxide, followed by physicochemical treatment, acetone defatting and other steps, finally obtaining granular, oil-free and carrier-free modified soybean lecithin.

[0003] During the production process, raw materials such as soybean lecithin, lactic acid, and hydrogen peroxide are added to a mixing tank in a certain proportion and mixed. Under stirring conditions, hydrogen peroxide reacts with the double bonds in the lecithin molecules under the catalysis of lactic acid to generate hydroxylated lecithin. After the reaction is completed, the reaction solution is neutralized with alkali and the pH value is adjusted to neutral or slightly alkaline. The hydroxylated soybean lecithin product is discharged from the mixing tank through the outlet and then processed further.

[0004] In the process of using the above-mentioned mixing equipment for phospholipid production, raw materials such as soybean phospholipids, lactic acid, and hydrogen peroxide are usually first mixed inside the mixing tank, and then stirred. This modification method requires a long stirring time in actual operation, thus reducing the efficiency of phospholipid modification. Utility Model Content

A conical plate 12 is provided on the outer side of the rotating rod 4, and the conical plate 12 is located below the strip-shaped channels 11.

The liquid flow control structure is movably fitted between the feeding hopper 13 and the flow channel 5. A cover plate 19 is provided on the top of the feeding hopper 13.
