Description

Technical Field

[0001] This invention relates to the field of egg white processing equipment technology, specifically to an egg white desalting and concentration device. Background Technology

[0002] An egg white desalting and concentration device is a specialized piece of equipment used to process egg whites or other egg products. Its main purpose is to remove salt from egg whites and concentrate their effective components for subsequent processing and utilization.

[0003] In existing desalting and concentration devices, permeation membrane separation is used to desalt egg white. However, a single permeation membrane filtration device has low desalting efficiency for egg white, requiring multiple filtration components. However, multiple filtration components increase costs. In addition, during conventional circulating filtration, the solution mixed with subsequent filters, causing salt to adhere to the egg white even after multiple desalinations, thus reducing desalting efficiency. Therefore, we propose an egg white desalting and concentration device. Summary of the Invention

[0004] To address the shortcomings of existing egg white desalting and concentration devices, this invention provides an egg white desalting and concentration device that includes a third and a fourth reverse osmosis filtration device. During the desalting and filtration process of the egg white, the filtered egg white is returned to the interior of a second solution placement tank. The second solution placement tank separates the filtered egg white to prevent mixing. Thus, the desalting efficiency can be maintained during the continuous desalting process of the filtration components, solving the problems mentioned in the background art.

[0005] This invention provides the following technical solution: an egg white desalting and concentration device, comprising a base plate, a mixing tank installed on one side of the upper part of the base plate, a centrifugal filter installed on one side of the mixing tank via a first conveying pipe, a first solution placement tank installed at the lower end of the centrifugal filter via a second conveying pipe, a first reverse osmosis filter installed at the lower end of the first solution placement tank via a third conveying pipe, a second reverse osmosis filter installed at the lower end of the first reverse osmosis filter via a fourth conveying pipe, a second solution placement tank installed at the lower end of the second reverse osmosis filter via a fifth conveying pipe, a third reverse osmosis filter installed at the lower end of the second solution placement tank via a sixth conveying pipe, a fourth reverse osmosis filter installed at the lower end of the third reverse osmosis filter via a seventh conveying pipe, a T-junction pipe installed at the lower end of the fourth reverse osmosis filter, a concentration device installed on one branch of the T-junction pipe, and drain outlets installed on the exterior of the first, second, third, and fourth reverse osmosis filters.

[0006] Preferably, each of the two branches of the three-way pipe is equipped with a set of valves, and the other branch inside the three-way pipe flows back into the interior of the second solution placement tank.

[0007] Preferably, each of the first, second, third, fifth, and tee pipes is equipped with a set of delivery pumps, and each delivery pump is controlled by an independent drive.

[0008] Preferably, the second solution placement box is installed between the first and second reverse osmosis filtration devices and the third and fourth reverse osmosis filtration devices, and each of the first, second, third, and fourth reverse osmosis filtration devices is equipped with a reverse osmosis desalination membrane.

[0009] Preferably, the mixing tank includes a mixing barrel, the top of which is fitted with a first top cover, the inside of which is fitted with a first inlet and a second inlet, a stirring rod is fitted in the middle of the first top cover, and a placement groove is fixed on the inner side of the first top cover and located at the lower end of the second inlet, and a strainer is movably sleeved at the lower end of the placement groove.

[0010] Preferably, a second gear is fixed to the outside of the stirring rod, a first gear is meshed between the sluice plate and the second gear, and the sluice plate has feed holes at equal intervals inside.

[0011] Preferably, the second solution placement box includes a placement box body, an inner sleeve is movably sleeved inside the placement box body, a second top cover is fitted on the top of the placement box body, a motor is installed on the side of the placement box body and on one side of the inner sleeve, and a gear installed on one end of the output shaft of the motor meshes with the inner sleeve.

[0012] Preferably, a partition is fixed inside the inner sleeve, and the sixth delivery pipe is fixed at an eccentric position at the lower end of the second solution placement box, with the sixth delivery pipe located directly below the three-way pipe.

[0013] Preferably, the concentration equipment includes a bracket fixed to the upper part of the base plate, an adjusting sleeve is movably sleeved on the outside of the bracket, a drying chamber is movably sleeved on the inner side of the two sets of adjusting sleeves, a drying chamber cover is installed at the top of the drying chamber, an exhaust port is opened inside one side of the drying chamber cover, and a heating component is installed at the lower end of the drying chamber.

[0014] Compared with existing egg white desalting and concentration devices, the present invention has the following advantages:

[0015] 1. This egg white desalting and concentration device feeds egg white and mixed liquid into the mixing tank through the first and second inlets. The stirring rod is activated, and the first and second gears mesh to drive the sieve plate to rotate, ensuring that the mixed liquid is discharged downwards evenly and that the egg white and mixed liquid are fully mixed, thereby improving the subsequent desalting efficiency.

[0016] 2. This egg white desalting and concentration device initially filters the egg white using a first and a second reverse osmosis filtration unit. The initially filtered egg white is then transported to the interior of a second solution placement tank. Simultaneously, a third and a fourth reverse osmosis filtration unit further filters the egg white. A three-way pipe allows the filtered egg white solution to flow back into the second solution placement tank, ensuring that the egg white undergoes multiple purification and filtration processes through the third and fourth reverse osmosis filtration units. This improves the desalting and filtration efficiency of the egg white. After purification, the valve is closed, and the egg white solution is transported through the other side of the three-way pipe to the concentration unit, where the egg white is dried and concentrated. This further enhances the desalting and purification effect of the egg white.

[0017] 3. This egg white desalting and concentration device, when the motor is started, drives the partition to rotate. When the partition rotates to the middle of the sixth conveying pipe, both the initially filtered solution and the solution filtered multiple times can be transferred to the interior of the third reverse osmosis filtration device for further filtration. When multiple desalting is required, the partition is controlled to separate the fifth conveying pipe and the three-way pipe. The three-way pipe carries the egg white that has been purified multiple times to one side, and it undergoes multiple purifications through the sixth conveying pipe. The egg white that has been initially purified by the first and second reverse osmosis filtration devices is then transported to the other side of the partition, avoiding the mixing of the initially purified and multiple purified solutions. Therefore, the purification efficiency of the egg white solution can be improved. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5An egg white desalting and concentration device includes a base plate 1. A mixing tank 2 is installed on one side of the upper part of the base plate 1. A centrifugal filter 4 is installed on one side of the mixing tank 2 via a first conveying pipe 3. A first solution placement tank 6 is installed at the lower end of the centrifugal filter 4 via a second conveying pipe 5. The centrifugal filter 4 centrifuges and filters the egg white solution to remove impurities. The first solution placement tank 6 further centrifuges the initially centrifuged egg white solution. A first reverse osmosis filter 8 is installed at the lower end of the first solution placement tank 6 via a third conveying pipe 7. A second reverse osmosis filter 10 is installed at the lower end of the first reverse osmosis filter 8 via a fourth conveying pipe 9. The first reverse osmosis filter 8 and the second reverse osmosis filter 10 perform preliminary desalting treatment on the egg white solution. A second solution placement tank 12 is installed at the end of the first reverse osmosis filter 8 via the fifth conveying pipe 11. A third reverse osmosis filter 14 is installed at the lower end of the second solution placement tank 12 via the sixth conveying pipe 13. A fourth reverse osmosis filter 16 is installed at the lower end of the third reverse osmosis filter 14 via the seventh conveying pipe 15. The third reverse osmosis filter 14 and the fourth reverse osmosis filter 16 purify the egg white multiple times to improve the desalting accuracy of the egg white. A three-way pipe 17 is installed at the lower end of the fourth reverse osmosis filter 16. A concentration device 18 is installed on one branch of the three-way pipe 17. A drain port 21 is installed on the outside of the first reverse osmosis filter 8, the second reverse osmosis filter 10, the third reverse osmosis filter 14 and the fourth reverse osmosis filter 16. The drain port 21 discharges the impurities generated during filtration.

[0026] Both branches of the three-way pipe 17 are equipped with a set of valves 19. The other branch inside the three-way pipe 17 flows back to the interior of the second solution placement tank 12. Two branches are installed on the outside of the three-way pipe 17, one of which is connected to the concentration device 18 and the other is connected to the second solution placement tank 12. When it is necessary to desalt the egg white, rotate the valve 19 to close the three-way pipe 17 connected to the concentration device 18. At the same time, the egg white solution flows back to the interior of the second solution placement tank 12 through the other three-way pipe 17 to desalt the egg white solution again. After multiple cycles of desalting, after ensuring the desalination degree, close the valve 19 connected to the second solution placement tank 12. At the same time, the desalted egg white is transported to the interior of the concentration device 18. The concentration device 18 dries the desalted egg white to improve the desalination degree of the egg white.

[0027] Each of the first conveying pipe 3, the second conveying pipe 5, the third conveying pipe 7, the fifth conveying pipe 11, and the three-way pipe 17 is equipped with a set of conveying pumps 20. Each conveying pump 20 is controlled by an independent drive. The conveying pumps 20 provide power for the flow of egg white. The structure of each pump is made of food-grade materials. The conveying pumps 20 are existing technology and mainly drive the transfer of egg white.

[0028] The second solution placement tank 12 is installed between the first reverse osmosis filter 8 and the second reverse osmosis filter 10, and between the third reverse osmosis filter 14 and the fourth reverse osmosis filter 16. Each of the first, second, third, and fourth reverse osmosis filter devices 8, 10, 14, and 16 is equipped with a reverse osmosis desalination membrane. The second solution placement tank 12 sequentially filters the egg white, ensuring efficient desalination and impurity removal. Simultaneously, the second solution placement tank 12 collects the initially filtered egg white, improving the controllability of the egg white desalination filtration process.

[0029] The mixing tank 2 includes a mixing drum 201. A first top cover 202 is fitted onto the top of the mixing drum 201. A first inlet 204 and a second inlet 205 are installed inside the first top cover 202. A stirring rod 203 is fitted onto the middle of the first top cover 202. A placement groove 206 is fixed on the inner side of the first top cover 202, below the second inlet 205. A strainer 207 is movably sleeved onto the lower end of the placement groove 206. The strainer 207 is mounted on the mixing drum 201 via the first top cover 202. At the top, egg whites can be fed into the mixing tank 201 through the first inlet 204, while auxiliary neutralizing materials are fed into the mixing tank 201 through the second inlet 205. The auxiliary neutralizing materials are fed downward through the strainer 207 to ensure that the egg whites and auxiliary neutralizing materials are fully mixed. The stirring rod 203 is activated to improve the fullness of the egg whites mixing and to add liquid to ensure that impurities in the egg whites are separated, which facilitates subsequent desalting and filtration.

[0030] A second gear 209 is fixed to the outside of the stirring rod 203. A first gear 208 is meshed between the sprue plate 207 and the second gear 209. The sprue plate 207 has equally spaced inlet holes. When the stirring rod 203 is started, it stirs the egg white and the neutralizing liquid. At the same time, when the stirring rod 203 rotates, it drives the sprue plate 207 to rotate through the first gear 208 and the second gear 209. The sprue plate 207 drives the auxiliary neutralizing material to be evenly discharged downwards, improving the uniformity and thoroughness of the mixing between the auxiliary neutralizing material and the egg white.

[0031] The second solution placement box 12 includes a placement box body 121, an inner sleeve 122 is movably fitted inside the placement box body 121, a second top cover 123 is fitted on the top of the placement box body 121, a motor 124 is installed on the side of the placement box body 121 and on one side of the inner sleeve 122, a gear installed on one end of the output shaft of the motor 124 meshes with the inner sleeve 122, and is installed inside the placement box body 121 through the inner sleeve 122, wherein the second top cover 123 is installed at the upper end of the placement box body 121, the fifth delivery pipe 11 and the three-way pipe 17 drive the egg white solution to be delivered to the inside of the inner sleeve 122, the motor 124 is started, the motor 124 drives the inner sleeve 122 to rotate, ensuring that the partition 125 remains in a rotating state inside the placement box body 121.

[0032] A partition 125 is fixed inside the inner sleeve 122. The sixth delivery pipe 13 is fixed at an eccentric position at the lower end of the second solution placement tank 12. The sixth delivery pipe 13 is located directly below the three-way pipe 17. When the partition 125 is moved to the middle of the placement tank body 121, the partition 125 is horizontally installed in the middle of the sixth delivery pipe 13. When the fifth delivery pipe 11 and the three-way pipe 17 transport the solution into the second solution placement tank 12, the solution can be transferred to the interior of the sixth delivery pipe 13 through both sides of the partition 125, and can then be transferred to the third reverse osmosis filtration device 14 and the fourth reverse osmosis filtration device 15 through the sixth delivery pipe 13. The internal filter of tube 6 is used for filtration. When the egg white that has been purified multiple times is purified again, the control partition 125 is moved to one side of the fifth delivery tube 11 to ensure that the partition 125 separates the fifth delivery tube 11 and the three-way tube 17. The three-way tube 17 drives the egg white that has been purified multiple times to be transported to the side biased towards the sixth delivery tube 13. At the same time, the fifth delivery tube 11 drives the egg white that has been initially filtered to the other side of the partition 125. That is, the sixth delivery tube 13 can filter the egg white that has been purified multiple times, and increase the concentration of the egg white purification. It also avoids the mixing of the initially filtered egg white with the egg white that has been filtered multiple times, thus avoiding the mixing of egg white and affecting the concentration of the egg white purification.

[0033] The concentration device 18 includes a support 181 fixed on the upper part of the base plate 1. An adjusting sleeve 182 is movably sleeved on the outside of the support 181. A drying chamber 183 is movably sleeved on the inner side of the two sets of adjusting sleeves 182. A drying chamber cover 184 is installed on the top of the drying chamber 183. An exhaust port is opened inside one side of the drying chamber cover 184. A heating component is installed at the lower end of the drying chamber 183. After the desalted and filtered egg white is transported into the concentration device 18 through the three-way pipe 17, the heating component installed inside the drying chamber 183 is activated to dry the egg white. This ensures that the egg white is heated and concentrated into egg white powder. After that, the position of the adjusting sleeve 182 inside the support 181 is controlled, and the drying chamber 183 is rotated to discharge the concentrated egg white powder.

[0034] Working Principle: During operation, the mixing tank 2, centrifugal filter 4, first solution placement tank 6, first reverse osmosis filter 8, second reverse osmosis filter 10, second solution placement tank 12, third reverse osmosis filter 14, fourth reverse osmosis filter 16, and concentration device 18 are sequentially installed on the upper part of the base plate 1, connected by pipes. Simultaneously, egg white, food-grade gelatin, and liquid are transported to the mixing tank 2. The stirring rod 203 is activated to mix the egg white, and the mixed solution is transported to the centrifugal filter 4 via the first conveying pipe 3. The centrifugal filter 4 uses centrifugation to filter impurities and gelatin containing 80% salt. The filtered egg white is then transported to the first solution placement tank 6, and then via the third conveying pipe 7 to the first reverse osmosis filter 8 and the second reverse osmosis filter 10. Inside, the first reverse osmosis filtration unit 8 and the second reverse osmosis filtration unit 10 use filter membranes to desalinate the egg white again. The initially desalted egg white is transported to the interior of the second solution placement tank 12. The third reverse osmosis filtration unit 14 and the fourth reverse osmosis filtration unit 16 filter the egg white multiple times and close a set of valves 19. The egg white is then carried back to the interior of the second solution placement tank 12 via a three-way pipe 17. That is, the egg white can be continuously filtered multiple times. The filtered solution accumulates inside the second solution placement tank 12. A rotating partition 125 separates the initially filtered egg white solution from the multiple filtered egg white, thereby improving the desalination efficiency of the egg white. After desalination, the solution is transported to the interior of the concentration unit 18 via the three-way pipe 17. The concentration unit 18 dries the egg white to ensure that the egg white is converted into egg white powder, thereby achieving the concentration efficiency of the egg white.
