Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of production of milk polar lipids, and particularly relates to a production method and device of milk polar lipids. BACKGROUND

[0002] Milk polar lipids (emulsified polar lipids) are a class of lipid molecules with polar and non-polar parts, usually existing 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 and cosmetics.

[0003] However, in the production process of milk polar lipids, a shell is needed, and milk polar lipids themselves have surface activity characteristics, which can reduce the surface tension of the liquid, so that bubbles are more easily formed, resulting in the generation of foam. When filtering, the formation of foam will hinder the flow of liquid, causing the filtering speed to slow down, thereby affecting the filtering efficiency. Secondly, when milk polar lipids need to be filtered, the milk polar lipids entering the shell will directly rush to the place opposite to the filter plate and the pipe opening, so that the filter screen and the pipe opening opposite to each other have a larger filtering load, and most of the milk polar lipids will pass through this place all the time, reducing the filtering effect, but the remaining parts still have good filtering effect.

[0042] By starting the motor 6, the synchronous pulleys 8 and 9 are meshed to drive the output rods 11 to rotate through the synchronous belt 10, and when the output rods 11 rotate, the poking block 12 is in contact with the filter plates 13 to make the filter plates 13 vibrate through the elastic force of the springs 4 to prevent the filter plates 13 from being blocked, enhance the flow of liquid, and promote the contact between particles and filter screens. When the sleeves 14 move up and down, the circular rods 16 slide up and down on the outer walls of the sleeves 14, the springs 19 are compressed, the guide blocks 17 slide in the arc-shaped grooves 15, the sleeves 14 rotate, the rotation of the sleeves 14 drives the swinging rods 21 to rotate, the iron cones 22 remove the bubbles formed on the surfaces of the filter plates 13, avoid the formation of foam to hinder the flow of liquid, and slow down the filtering speed, thereby affecting the filtering efficiency.

[0044] The above scheme is adopted: the milk polar lipids are dispersed into the shell 1 through the guide holes opened by 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, avoiding 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, causing the filtration load to be large and the filtration effect to be 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 residue will be discharged through the diverter holes set in the diverter barrel 24 and the guide plate 25, avoiding the accumulation of residue in the diverter barrel 24 and the guide plate 25 and avoiding the clogging of the diverter holes of the diverter barrel 24 and the guide plate 25 due to long-term use.

[0045] like Figures 1 to 8 As shown, one side of the lower sleeve 14 is fixedly connected to a fixing rod 28, and the side of the fixing rod 28 away from the lower circular rod 16 is fixedly connected to the shell 1, and an inclined groove 29 is provided at the inner bottom of the shell 1.

[0046] Adopt the above scheme: through the setting of fixed rod 28 for supporting the lower circular rod 16, through the setting of inclined groove 29 makes the filtered milk polar lipid flow to the discharge pipe 30 to discharge, increase fluidity, filter plate 13 is divided into two layers, the upper layer is coarse filter screen mainly used for removing large particles and impurities, the lower layer is fine filter screen responsible for removing small particles and fine impurities, make the filtration more fine, through the opening of inspection door 31 can penetrate the use of filter plate 13, at the same time can open the cleaning residue on the filter plate 13, sealing gasket 32 can make the inspection door 31 more sealed when closing.

[0047] The working principle and use process of the application are as follows:

[0048] When the milk polar lipid needs to be filtered in the production process, when the milk polar lipid needs to be filtered in the production process, first, the milk polar lipid is introduced into the shell 1 through the feed pipe 23 and the flow distribution barrel 24, when the milk polar lipid enters the flow distribution barrel 24, it is dispersed into the shell 1 through the flow guide hole of the flow distribution barrel 24 and the flow guide plate 25, and then the dispersed milk polar lipid is uniformly distributed on the filter plate 13, avoiding the milk polar lipid entering the shell 1 directly to the opposite side of the feed pipe 23 and the filter plate 13, so that the filtering load is larger and the filtering effect is reduced.

[0049] When the milk polar lipid enters the shell 1, the motor 6 is started to make the synchronous wheel one 8 and the synchronous wheel two 9 engage through the synchronous belt 10 to drive the output rod 11 to rotate, when the output rod 11 rotates, the toggle block 12 is in contact with the filter plate 13, so that the filter plate 13 is shaken by the elastic force of the spring one 4 to prevent the filter plate 13 from being blocked, enhance the flow of liquid, promote the contact between particles and filter screen, at the same time, the sleeve 14 is driven to move up and down, when the sleeve 14 moves up and down, it slides up and down on the outer wall of the circular rod 16, so that the spring two 19 is compressed, at the same time, the guide block 17 slides in the arc-shaped groove 15, so that the sleeve 14 rotates, 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, avoids the formation of foam to hinder the flow of liquid, causes the filtering speed to slow down, thereby affecting the filtering efficiency;

[0050] At the same time, the sleeve 14 rotates to drive the connecting rod 26 fixedly connected to the upper sleeve 14 to rotate, when the connecting rod 26 rotates, the scraper rod 27 is driven to rotate, and the inner wall of the flow distribution barrel 24 and the flow guide plate 25 is scraped, then the residue scraped will be discharged through the flow distribution hole of the flow distribution barrel 24 and the flow guide plate 25, avoiding the accumulation of residue in the flow distribution barrel 24 and the flow guide plate 25 and avoiding the blockage of the flow distribution hole of the flow distribution barrel 24 and the flow guide plate 25 caused by long-term use.
