DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the production of special medical formula foods, the concentration device of special protein powder is one of the key equipment. This device is mainly used to increase the concentration of protein solution for subsequent processing and analysis. Membrane separation technology is a special separation technology that can effectively separate protein from solution by selecting membranes with different pore sizes. This technology has the advantages of high efficiency, simple operation, mild conditions, etc., and is widely used in the concentration and purification of biological products.

[0038] Embodiment 1:

[0039] In the process of increasing the concentration of protein solution, it is necessary to remove the water from the protein solution. In the process of separating water, the existing device directly uses the membrane for permeation, but the separation efficiency is low. In order to improve the quality of concentration, combined with Figure 1-Figure 7As shown, a concentrating device for producing special protein powder for special medical food provided by the present invention includes a shell 100 as a carrier of the entire device, a material box 103 for containing protein solution is fixedly installed on the back of the shell 100, and a pump body 104 for conveying protein solution is fixedly installed on the material box 103. A separation mechanism 300 for separating water is provided in the shell 100, and a pressure mechanism 200 for improving the efficiency of water separation is also provided on the shell 100.

[0040] Since the membrane is generally laid flat when filtering water through the membrane, the plane space occupied by the membrane is large, which will cause a certain amount of lateral space waste and make it difficult to continuously transport the protein solution for separation and treatment. In order to reduce the lateral space occupied by the membrane, the guide frames 301 on both sides of the housing 100 are installed obliquely. The guide frames 301 are stepped. The stepped guide frames 301 are helpful to improve production efficiency and can process more solutions in a shorter time. The two guide frames 301 are symmetrically distributed. A groove body 302 is provided in the guide frame 301. A plurality of connecting covers 303 are fixedly connected to the guide frame 301. The bottom wall of the guide frame 301 is provided with a reverse osmosis membrane 310. 01 is provided with a baffle 307 for discharging the solution at the outlet, a motor 308 is fixedly mounted on the housing 100, and the end of the motor 308 is connected to the baffle 307. The protein solution enters the slot 302 of the guide frame 301. The two guide frames 301 are symmetrically distributed in an inclined manner, which can reduce the horizontal floor space and facilitate the discharge of the protein solution after the separation of water, and then continue to transport the unseparated protein solution into the guide frame 301 to achieve continuous concentration of the protein solution. The ladder-shaped structure of the guide frame 301 helps to create more ideal flow conditions. When discharging the protein solution, such as moderate turbulence, this helps to prevent the deposition of solutes on the membrane surface and reduce concentration polarization. Concentration polarization will lead to an increase in the concentration of solutes on the surface of the permeable membrane, thereby reducing the effective osmotic pressure difference and the flux of the membrane.

[0041] When air pressure is applied to the protein solution, as the water content of the protein solution decreases, the air pressure remains at a stable value, which will cause the solution flow rate in the reverse osmosis process to be too slow, the concentration efficiency to be low, and it will take a longer time to complete the concentration process. Therefore, a pressure mechanism 200 is provided to improve the efficiency of osmosis. The pressure mechanism 200 includes a transmission sleeve 201 fixedly connected to the outer shell 100, and a gas tank 206 for storing argon gas is also installed on the outer shell 100. An air pump a205 for conveying argon gas is installed on the outer shell 100. The air pump a205 is connected to the gas tank 206 and the connecting cover 303 through pipelines respectively. The bottom of the transmission sleeve 201 is connected and installed with a guide pipe 204, and the guide pipe 204 is connected to the tank body 302 through a pipeline. A piston a202 is slidably connected in the transmission sleeve 201, and the air pump a205 introduces the argon gas in the gas tank 206 into the transmission sleeve 201. Then the argon gas enters the connecting cover 303 through the guide tube 204, and pressurizes the protein solution in the tank body 302, so that the water in the protein solution passes through the reverse osmosis membrane 310, and the water is separated to achieve the concentration of the protein solution. A pressing component 203 for applying different air pressures is provided on the transmission sleeve 201. As the water content of the protein solution continues to decrease, the air pressure is increased, and the water can be further separated. As the water is separated, the protein concentration in the protein solution will gradually increase. Increasing the air pressure can further promote the separation of water, thereby further increasing the protein concentration.

[0042] Furthermore, the bottom wall of the outer shell 100 is provided with a plurality of guide grooves 102 for draining out water and separated protein solution, and a plurality of receiving boxes 101 for collecting water and separated protein solution are placed at the bottom of the outer shell 100, and the separated water and protein solution respectively enter the corresponding receiving boxes 101 through the guide grooves 102.

[0043] According to the embodiment, since argon gas is injected into the connection cover 303, the protein solution located at the lower part of the guide frame 301 will not rise to the top of the connection cover 303. Then, the protein solution can be pressurized by compressed gas to improve the separation effect.

[0044] Embodiment 2:

[0045] As the amount of water in the protein solution decreases, the total amount of the protein solution will also decrease. The protein solution at a high position will flow obliquely downward. There is no protein solution blocking the reverse osmosis membrane 310 above. The reverse osmosis membrane 310 will be directly pressurized by the air pressure, which will increase the damage to the reverse osmosis membrane 310. In order to reduce the damage to the reverse osmosis membrane 310, the reverse osmosis membrane 310 is combined with the reverse osmosis membrane 310 to reduce the damage to the reverse osmosis membrane 310. Figure 4-Figure 8As shown, on the basis of the first embodiment, by providing a protective component 309 for protecting the reverse osmosis membrane 310 on the outer shell 100, the reverse osmosis membrane 310 can be protected, which is beneficial to improving the service life of the reverse osmosis membrane 310, and an air bag 306 for compensating space is provided on the connecting cover 303. The setting of the air bag 306 can reduce the space in the guide frame 301 when the total amount of protein solution is reduced, thereby ensuring the stability of the air pressure and better separating the water in the protein solution.

[0046] The protection component 309 includes a transmission shaft 3091 rotatably mounted on both sides of the housing 100, and a protection sheet 3092 is mounted on the transmission shaft 3091. The ends of the protection sheet 3092 extend to the inside of the guide frame 301 through a slide groove. Two floats 3093 are fixedly connected to the ends of the protection sheet 3092. A handwheel 3094 is fixedly connected to the ends of the transmission shaft 3091. As the protein solution decreases, the float 3093 slides obliquely downward, and the float 3093 pulls the protection sheet 3092 to lay on the reverse osmosis membrane 310, thereby continuously protecting the reverse osmosis membrane 310 without protein solution.

[0047] Since the shell 100 is an open space, the water is continuously separated, resulting in a decrease in the total amount of the solution, and the original space will increase. The gas will be redistributed to other positions to fill the blank area, causing the air pressure to drop, which will reduce the penetration rate of the protein solution. The airbag 306 is fixedly connected to the inner wall of the connecting cover 303, and the connecting cover 303 is fixedly connected with an air pump b304 for inflating the airbag 306. The air pump b304 is fixedly connected with an air outlet pipe 305 connected to the airbag 306, and the other end of the air pump b304 extends to the outside of the shell 100 through a catheter. After the solution is reduced, the air pump b304 starts to inflate the airbag 306 through the air outlet pipe 305, so that the airbag 306 expands to compensate for the space after the solution is reduced, so as to keep the pressure in the system stable and ensure the quality of penetration.

[0048] Since the protein solution is continuously decreasing, in order to fill the space left by the reduction of the solution, a rotary encoder 3095 rotatably connected to the transmission shaft 3091 is fixedly mounted on the housing 100. A single-chip microcomputer is also provided in the housing 100 to control the operation of the air pump b304. When the protective sheet 3092 moves, the transmission shaft 3091 is driven to rotate. The rotary encoder 3095 senses the rotation of the transmission shaft 3091 and can control the air pump b304 through the single-chip microcomputer, so that it can adaptively control the expansion of the airbag 306 as the solution decreases.

[0049] According to the embodiment, the expansion of the automatic regulating airbag 306 can be precisely controlled according to the reduction of the solution amount, which can avoid damage to the airbag 306 due to over-inflation and extend the service life of the device.

[0050] Embodiment three:

[0051] Combination Figure 4 , Fig. 9 and Fig.10 As shown, on the basis of the first embodiment, the pressing assembly 203 includes a connecting rod 2031 fixedly connected to the piston a202, a bracket 2033 is fixedly connected to the top of the connecting rod 2031, a spring b2032 is fixedly connected between the transmission sleeve 201 and the bracket 2033, a motor 2034 is fixedly mounted on the housing 100, a transmission disc 2035 is fixedly connected to the output end of the motor 2034, a plurality of transmission blocks 2036 for pressing the piston a202 are fixedly connected to the outer wall of the transmission disc 2035, and the motor 2034 starts the driving The transmission disk 2035 rotates, and the transmission disk 2035 drives multiple transmission blocks 2036 to rotate. When the transmission block 2036 contacts the bracket 2033 and pushes it down, the piston a202 descends with the bracket 2033 to pressurize the gas. Then the transmission block 2036 separates from the bracket 2033, and the spring b2032 pushes the bracket 2033 to reset. Through the above steps, the gas can be continuously pressurized and reduced, the formed concentration gradient can be destroyed, the polarization phenomenon can be reduced, and the separation efficiency of the membrane can be improved.

[0052] During the solution concentration process, as the water content in the solution decreases, the concentration of the solution will increase and the solute concentration gradient will become larger. In order to maintain the normal operation of the membrane separation system, a greater pressure is required to promote the permeation process of water through the membrane. Increasing the pressure can compensate for the decrease in permeation rate caused by the reduction in water content, thereby ensuring the separation effect and operating efficiency. The lengths of the multiple transmission blocks 2036 are different, and the lengths of the multiple transmission blocks 2036 increase sequentially. As the water content of the protein solution decreases, each time the pressure applied becomes larger and larger, excess water is separated.

[0053] According to the embodiment, the change in pressure can promote the solvent to pass through the membrane pores of the reverse osmosis membrane 310 more effectively, thereby improving the water permeability of the reverse osmosis membrane 310. This effect is more obvious when treating a solution containing macromolecular solutes.

[0054] Embodiment 4:

[0055] When the water and protein solution are continuously separated, gas loss will occur and the gas pressure will decrease. The decrease in gas pressure may reduce the driving force in the membrane separation process, thereby reducing the separation efficiency. In order to maintain the permeation effect, combined with Figure 1-Figure 10As shown, on the basis of the first embodiment, a connecting sleeve 207 connected thereto is fixedly connected to the transmission sleeve 201, a piston b208 is slidably connected inside the connecting sleeve 207, a spring a209 is fixedly connected between the piston b208 and the inner wall of the connecting sleeve 207, a transmission rod 210 slidably connected to the connecting sleeve 207 is fixedly connected to the piston b208, the transmission rod 210 is located in the middle of the spring a209, but the spring a209 does not contact the transmission rod 210, a touch button 212 is installed on the connecting sleeve 207, a connector 211 corresponding to the touch button 212 is fixedly connected to the end of the transmission rod 210, and the touch button 212 is connected to the air Pump a205 is electrically connected and is used to compensate for argon. With the continuous change of pressure increase and pressure reduction, part of the argon will be discharged along with the discharge of water. The reduction of argon causes spring a209 to push piston b208 to move inward. Piston b208 drives connector 211 to move through transmission rod 210. Then connector 211 contacts touch button 212, and air pump a205 is started to continue to inject argon into transmission sleeve 201 and supplement nitrogen to ensure the continuity and stability of pressure. This not only helps to maintain the stability of the membrane separation process, but also effectively protects the structure of protein and improves the separation and purification effect.
