[0002] Milk polar lipids (emulsifying polar lipids) are a class of lipid molecules with polar and non-polar parts, which are usually found in biological membranes, especially in cell membranes and dairy products. They have good solubility in water and can form emulsions, and are widely used in food, medicine, cosmetics and other fields.

[0003] However, in the production process of milk polar lipids, a shell is needed, and the milk polar lipids themselves have surface active properties, which can reduce the surface tension of the liquid, making it easier to form bubbles, resulting in the generation of foam. The formation of foam during filtration will hinder the flow of the liquid, causing the filtration speed to slow down, thereby affecting the filtration efficiency; secondly, when the milk polar lipids need to be filtered, the milk polar lipids enter the shell and will directly rush to the place where the filter plate is opposite to the pipe port, causing the filtration load to be larger at the place where the filter screen is opposite to the pipe port.

Raw material preparation, selecting fatty acids and glycerol as raw materials; S2, synthesis reaction, combining fatty acids and glycerol to form triglycerides through chemical or enzymatic reactions; S3, emulsification treatment, mixing the synthesized triglyceride with water, and forming a stable emulsion by stirring or high-pressure homogenization. This step requires the use of an emulsifier to improve the stability of the emulsion; S4, separation and purification, removing unreacted raw materials and impurities by filtering, centrifuging or membrane separation to obtain initial milk polar lipids; S5. Quality testing: various physical and chemical properties of the initial milk polar lipids are tested, including emulsification ability, stability and purity, to ensure that they meet the application requirements and obtain milk polar lipids.

[0022] The above scheme is adopted: the motor 6 is turned on so that the synchronous wheel 1 8 and the synchronous wheel 2 9 are meshed through the synchronous belt 10 to drive the output rod 11 to rotate. When the output rod 11 rotates, the toggle block 12 contacts the filter plate 13, so that the filter plate 13 is shaken by the elastic force of the spring 1 4 to prevent the filter plate 13 from being blocked, thereby enhancing the flow of liquid and promoting the contact between particles and the filter screen.

[0024] The above scheme is adopted: the milk polar lipids are dispersed into the shell 1 through the guide holes opened in the diverter barrel 24 and the guide plate 25, and then the dispersed milk polar lipids will be evenly distributed on the filter plate 13, so as to avoid the milk polar lipids directly rushing to the place opposite to the feed pipe 23 and the filter plate 13 when entering the shell 1, so that the filtering load is large and the filtering effect is reduced. When the connecting rod 26 rotates, the scraper rod 27 is driven to rotate to scrape the inner walls of the diverter barrel 24 and the guide plate 25, and then the scraped residues will be discharged through the diverter holes set in the diverter barrel 24 and the guide plate 25, so as to avoid the accumulation of residues in the diverter barrel 24 and the guide plate 25 and avoid the diverter holes of the diverter barrel 24 and the guide plate 25 being blocked due to long-term use.

[0025] like Figures 1 to 8 As shown, a fixing rod 28 is fixedly connected to one side of the lower sleeve 14, and the fixing rod 28 is fixedly connected to the shell body 1 on the side away from the lower circular rod 16. An inclined groove 29 is provided at the inner bottom of the shell body 1, and a discharge pipe 30 is penetrated and provided on the side of the bottom of the shell body 1 away from the support plate 5, and the discharge pipe 30 cooperates with the inclined groove 29. The filter plate 13 is divided into an upper and lower layers, the upper layer is a coarse filter screen mainly used to remove larger particles and impurities, and the lower layer is a fine filter screen responsible for removing smaller particles and fine impurities.

Sealing pads 32 are installed on the tops of the two inspection doors 31, and the inner walls of the diversion barrel 24 and the guide plate 25 are penetrated and provided with evenly distributed diversion holes.

[0026] The above scheme is adopted: the fixed rod 28 is set to support the lower circular rod 16, and the filtered milk polar lipids are discharged to the lower feeding pipe 30 through the setting of the inclined groove 29 to increase fluidity. The filter plate 13 is divided into an upper and lower layer. The upper layer is a coarse filter mesh mainly used to remove large particles and impurities, and the lower layer is a fine filter mesh responsible for removing small particles and fine impurities, making the filtration more refined. By opening the inspection door 31, the use of the filter plate 13 can be seen, and the residue on the filter plate 13 can be opened and cleaned. The sealing gasket 32 ​​can make the inspection door 31 more sealed when closed.

[0027] The working principle and use process of the present invention: When the milk polar lipid needs to be filtered during the production process, the milk polar lipid is firstly passed through the feed pipe 23 and the diverter barrel 24 into the housing 1. When the milk polar lipid enters the diverter barrel 24, it is dispersed into the housing 1 through the diversion holes provided by the diverter barrel 24 and the guide plate 25. Then the dispersed milk polar lipid is evenly distributed on the filter plate 13, so as to avoid the milk polar lipid directly rushing to the feed pipe 23 and the filter plate 13 and the relative places when entering the housing 1, so that the filtering load is large and the filtering effect is reduced; When the milk polar lipid enters the housing 1, the motor 6 is turned on to make the synchronous wheel 1 8 mesh with the synchronous wheel 2 9 through the synchronous belt 10 to drive the output rod 11 to rotate. When the output rod 11 rotates, the toggle block 12 contacts the filter plate 13, so that the filter plate 13 is shaken by the elastic force of the spring 1 4 to prevent the filter plate 13 from being blocked, thereby enhancing the flow of liquid and promoting the contact between particles and the filter screen. When the filter plate 13 shakes up and down, the sleeve 14 is driven to move up and down. When the sleeve 14 moves up and down, it will slide up and down on the outer wall of the circular rod 16, so that the spring 2 19 is compressed, and at the same time, the guide block 17 slides in the arc groove 15 to rotate the sleeve 14. The rotation of the sleeve 14 drives the swing rod 21 to rotate so that the iron cone 22 removes the bubbles formed on the surface of the filter plate 13, thereby avoiding the formation of foam that hinders the flow of liquid, resulting in a slow filtration speed, thereby affecting the filtration efficiency. When the sleeve 14 rotates, the connecting rod 26 fixedly connected to the upper sleeve 14 will be driven to rotate. When the connecting rod 26 rotates, the scraper rod 27 will be driven to rotate, so as to scrape the inner walls of the diverter barrel 24 and the guide plate 25. Then the scraped residue will be discharged through the diverter holes provided in the diverter barrel 24 and the guide plate 25, so as to avoid the accumulation of residue in the diverter barrel 24 and the guide plate 25 and the blockage of the diverter holes of the diverter barrel 24 and the guide plate 25 due to long-term use.
