Description

Technical Field

[0001] This invention belongs to the field of soy sauce dialysis technology, specifically a soy sauce desalination device and desalination method based on dialysis technology. Background Technology

[0002] Soy sauce, a traditional fermented condiment, typically requires the addition of 16% to 18% high-concentration salt during its production to inhibit microbial growth and ensure product stability. However, modern medical research indicates that long-term consumption of high-salt foods increases health risks such as hypertension, cardiovascular disease, and kidney disease. With increasing consumer health awareness, the market demand for low-salt soy sauce is growing. Therefore, effectively reducing the salt content of soy sauce while preserving its original flavor and nutritional components, and minimizing the loss of flavor substances such as amino acids, has become a critical technical problem that urgently needs to be solved in the soy sauce processing industry.

[0003] Chinese invention patent CN102613673B discloses a device for continuous desalination of soy sauce residue. It includes a shell, a desalting agent inlet, a feed inlet, a waste liquid outlet, and a discharge outlet provided on the shell. Inside the shell, there is also a hopper circulation mechanism. The hopper circulation mechanism mainly consists of a power source, a circulation transmission mechanism, and multiple hoppers. The circulation transmission mechanism is a vertical circulation transmission mechanism consisting of two transmission wheels that serve as the driving wheel and the driven wheel, respectively, and a transmission chain / belt driven by the transmission wheels.

[0004] While existing traditional desalination technologies (such as dilution, electrodialysis, and reverse osmosis) can achieve a certain degree of desalination, they still suffer from problems such as low desalination efficiency, high amino acid loss rate, high energy consumption, or complex equipment.

[0005] When using dialysis bags to dialyze soy sauce, the soy sauce located in the center of the dialysis bag cannot fully contact the deionized water for dialysis. Furthermore, the dialysis bag is easily blocked by substances in the soy sauce, affecting the normal excretion of subsequent ions and further reducing the dialysis effect of the soy sauce.

[0006] Meanwhile, ions from the soy sauce enter the deionized water along the dialysis bag. Under the influence of gravity, the ions fall and settle at the bottom of the deionized water, resulting in different ion concentrations at different depths. This affects the dialysis efficiency of the deionized water for the soy sauce inside the dialysis bags at different heights. Furthermore, when the ion concentration of the soy sauce inside the dialysis bag changes, existing technologies cannot adaptively adjust the dialysis effect, thus affecting the quality of the subsequently recovered soy sauce.

[0007] When the dialysis bag shakes inside the deionized water and collides and mixes with the support rod, the tensile force on both ends of the dialysis bag increases, making it easy for the bag to detach from the hose clamp, thereby reducing the sealing performance of the connector and the dialysis bag assembly.

[0008] However, if a dialysis bag in a certain location is unable to dialyze the soy sauce inside due to its own reasons, the operator needs to stop the machine to replace it, which will affect the normal dialysis work of the other dialysis bags and reduce dialysis efficiency. Summary of the Invention

[0009] To address the above problems, this invention provides a soy sauce desalination device and method based on dialysis technology.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a soy sauce desalting device based on dialysis technology, comprising a housing section, wherein multiple dialysis bags are movably connected inside the housing, and further comprising: The clamping part is movably connected to the inside of the housing part, and the clamping part includes a plug tube and an iron half-ring movably connected to the outer surface of the plug tube; The guide section is evenly distributed inside the box body. The guide section includes a positioning shell and a sliding block that slides inside the positioning shell. When the ion concentration of soy sauce inside the dialysis bag increases, the sliding block causes the dialysis bag to move up and down by an increased amount. The pressing part is fixedly connected inside the box body. The pressing part includes a support rod and movable blocks movably connected to both sides of the support rod. When the vertical movement of the dialysis bag increases, the amount of compression between the bag and the support rod increases. The amount of movement of the movable blocks along both sides of the support rod increases. The ferrous semi-ring drives the dialysis bag to move more on the outer surface of the insertion tube.

[0011] This application enables the dialysis removal of chloride and sodium ions from the inside of soy sauce, ensuring dialysis efficiency, improving dialysis effect, meeting actual processing and production needs, and is simple to operate, safe and stable. At the same time, during the dialysis process, it realizes the mixing and stirring of soy sauce inside the dialysis bag, the flow and mixing of deionized water, and the adaptive adjustment of the clamping position and clamping force at the end of the dialysis bag to ensure the continuous and stable operation of the dialysis bag.

[0012] Preferably, the housing portion further includes: The bottom box has a lid on top, and handles are provided on the outer surfaces of both the bottom box and the lid; The input tubes are evenly distributed above one side of the box cover. The output end of the input tubes is connected to the insertion tube on the side away from the dialysis bag via a connecting hose. Soy sauce flows into the dialysis bag along the input tubes and the connecting hose. The output tubes are evenly distributed on the other side of the box cover. The input end of the output tube is connected to the insertion tube on the side away from the dialysis bag via a connecting hose. The soy sauce inside the dialysis bag enters the output tube along the connecting hose and is discharged. A concentration sensor is installed inside the output tube to detect the concentration of ions in the soy sauce discharged along the output tube.

[0013] Preferably, the housing portion further includes: The inlet pipe is connected to the upper side wall of the bottom tank near the outlet pipe, and deionized water enters the bottom tank along the inlet pipe. The recovery tube is connected to the lower side wall of the bottom tank near the input tube. The deionized water inside the bottom tank is discharged along the recovery tube. The flow direction of the deionized water inside the bottom tank is opposite to the flow direction of the soy sauce inside the dialysis bag. The mounting bracket is fixedly connected to the inside of the base box, and multiple through holes are evenly opened inside the mounting bracket. The positioning shell is fixedly connected to the bottom of the through hole, the sliding block is movably connected to the inside of the through hole, and the side walls of the support rod are fixedly connected to the inner wall of the mounting bracket.

[0014] Preferably, the clamping part further includes: A retaining ring is fixedly connected to the outer surface of the insertion tube and engaged with the side wall of the sliding block. The diameter of the retaining ring is larger than the diameter of the insertion tube, and it is used to limit the insertion depth of the insertion tube. The hose clamp is snapped and fixed to the outer surface of the ferrous semi-ring, with the end of the dialysis bag located between the ferrous semi-ring and the hose clamp, to achieve snap-fit ​​fixation of the dialysis bag.

[0015] Preferably, the clamping part further includes: An elastic block is symmetrically fixed to the side wall of the ferrous semi-ring. The elastic block is elastic. Multiple movable blocks located near the sliding block are magnetic. The ferrous semi-ring is ferromagnetic. There is a magnetic attraction between the ferrous semi-ring and the movable blocks. The insertion tube causes the ferrous semi-ring to move downward by a larger amount. The magnetic attraction applied by the movable blocks to the ferrous semi-ring increases, and the ferrous semi-ring moves away from the sliding block end by a larger amount. A tapered sleeve is fitted onto the outer surface of the insertion tube. The diameter of the tapered sleeve gradually increases from one end of the sliding block to the other end, and the inner wall of the ferrous semi-ring is elastically and slidably connected to the outer surface of the tapered sleeve. A limiting guide ring is fixedly connected to the end of the insertion tube away from the sliding block, and is located on the inner wall of the dialysis bag. It guides the flow of soy sauce from inside the dialysis bag into the insertion tube. A buffer portion is provided between the limiting guide ring and the ferrous semi-ring, located on the outer surface of the insertion tube. This buffer portion is elastic. Preferably, the actuating part further includes: The telescopic component is fixedly connected inside the positioning shell, and the top output end of the telescopic component is fixedly connected to the bottom of the sliding block, which is used to drive the sliding block to move up and down along the through hole. The matching hole is located inside the sliding block, and the inner wall of the matching hole is provided with internal threads. The outer surface of the end of the insertion tube is provided with external threads. The side of the insertion tube away from the dialysis bag is threadedly inserted and fixed to the matching hole.

[0016] Preferably, the actuating part further includes: A horizontal plate is fixedly connected between two adjacent sliding blocks. When the sliding blocks move up and down, they cause the horizontal plate to move up and down. The bottom hole is evenly distributed inside the positioning shell, and a one-way liquid inlet valve is installed inside the bottom hole. The deionized water inside the bottom tank enters the positioning shell one-way upward through the one-way liquid inlet valve inside the bottom hole. The top holes are evenly distributed inside the horizontal plate. A one-way discharge valve is installed inside the top holes. The deionized water inside the positioning shell is discharged upwards through the one-way discharge valve inside the top holes.

[0017] Preferably, the pressing part further includes: The receiving hole is located inside the support rod. The bottom of the receiving hole corresponds to the top of the top hole and its diameter is smaller than that of the top hole. It is used for the flow of deionized water. The reset component is symmetrically arranged on both sides of the support rod, and its other end is fixedly connected to the side wall of the moving block. The receiving holes are all connected to the interior of the reset component. The deionized water discharged upward from the top hole enters the interior of the reset component through the receiving hole. The volume of the reset component increases and drives the moving block to move away from the end of the support rod.

[0018] The desalination method of the soy sauce desalination device based on dialysis technology, as described above, includes the following steps: S1. Both ends of the dialysis bag are fitted onto the outer surface of the insertion tube. The flow direction of soy sauce inside the dialysis bag is opposite to the flow direction of deionized water on the outer surface of the dialysis bag. The ions of soy sauce inside the dialysis bag are discharged into the deionized water. S2. When the ion concentration inside the dialysis bag increases, the sliding block causes the dialysis bag to move up and down inside the positioning shell, the pressure between the dialysis bag and the support rod and the moving block increases, the mixing degree of soy sauce inside the dialysis bag increases, the upward flow efficiency of deionized water increases, the amount of movement of the moving block away from the support rod increases, and the lateral pushing force on the soy sauce inside the dialysis bag increases. S3. When the downward movement of the dialysis bag increases, the ferrous semi-ring causes the end of the dialysis bag to move further away from the sliding block along the insertion tube, and the squeezing force exerted by the ferrous semi-ring on the inner wall of the dialysis bag increases. S4. When the ion concentration inside the dialysis bag reaches its maximum value, the sliding block drives the dialysis bag to move downward to the maximum distance. The bottom of the dialysis bag is pressed and blocked by the top of the support rod. Soy sauce no longer flows inside the dialysis bag. The iron semi-ring drives the end of the dialysis bag to move away from the sliding block to the maximum distance and presses it to the limit.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the high chemical tolerance of the RC membrane supports high-temperature dialysis at 40°C to accelerate ion migration, shorten the desalination cycle, and achieve the dual effects of efficient desalination and flavor retention. It is easy to operate and suitable for industrial production, and has greater efficiency and nutrient retention advantages than traditional electrodialysis.

[0020] 2. In this invention, the dialysis bag moves up and down inside the deionized water and is squeezed and collided with the support rod and the moving block, thereby mixing and stirring the soy sauce inside the dialysis bag and improving the dialysis effect of the soy sauce and deionized water.

[0021] 3. In this invention, deionized water continuously flows upward and mixes, avoiding the precipitation of ions inside the deionized water and affecting the uniformity of dialysis of soy sauce inside the dialysis bag. In addition, the moving block moves back and forth along both sides of the support rod to improve the lateral pushing and mixing effect on the dialysis bag.

[0022] 4. In this invention, the ferrous semi-ring drives the end of the dialysis bag to move laterally on the outer surface of the conical sleeve, which not only ensures distance compensation when the dialysis bag is squeezed and collided with the support rod, but also adjusts the squeezing force of the ferrous semi-ring and the hose clamp on the dialysis bag to ensure the stability of the insertion of the dialysis bag and the insertion tube.

[0023] 5. In this invention, when a dialysis bag loses its dialysis function, the sliding block moves both sides of the dialysis bag downwards to the maximum distance, so that the dialysis bag and the support rod are squeezed and sealed. The ferrous semi-ring exerts the maximum squeezing force on the end of the dialysis bag and prevents it from detaching, thereby avoiding multiple shutdowns and reducing dialysis efficiency.

[0026] 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.

[0027] First Embodiment like Figures 1 to 3 As shown, the soy sauce desalination device based on dialysis technology includes a housing 1, which is internally connected to multiple dialysis bags 111. Soy sauce flows slowly inside the dialysis bags 111. The dialysis bags 111 use regenerated cellulose (RC) membranes with a molecular weight cutoff of 100 Daltons (Da), and are resistant to pH values ​​of 2-12 and operating temperatures of 4-60℃. Their symmetrical pore distribution can accurately retain amino acids (average molecular weight 75-200 Da) and macromolecular flavor substances in the soy sauce, while allowing salt ions such as Na⁺ (23 Da) and Cl⁻ (35.5 Da) to diffuse freely into deionized water. The desalination rate can reach more than 70%. In addition, the high chemical tolerance of the regenerated cellulose (RC) membrane supports high-temperature dialysis at 40℃ to accelerate ion migration and shorten the desalination cycle. It has advantages in efficiency and nutrient retention compared to traditional electrodialysis methods.

[0028] The box body 1 also includes: a bottom box 101, with a box cover 102 on its top, the box cover 102 sealingly covering the bottom box 101, and handles 103 on the outer surfaces of both the bottom box 101 and the box cover 102, which facilitates opening the box cover 102; an input pipe 104, which is evenly arranged above one side of the box cover 102, and the output end of the input pipe 104 is connected to the insertion pipe 201 on the side away from the dialysis bag 111 through a connecting hose 106, which facilitates the flow of soy sauce inside the bag, and the soy sauce flows into the dialysis bag 111 along the input pipe 104 and the connecting hose 106, and the flow speed of the soy sauce is relatively slow, which facilitates the thorough and effective dialysis treatment of the soy sauce inside the dialysis bag 111.

[0029] The output pipes 105 are evenly arranged on the other side of the box cover 102. The input end of the output pipe 105 is connected to the insertion pipe 201 on the side away from the dialysis bag 111 through the connecting hose 106. There are generally six input pipes 104 and six output pipes 105, and two rows are arranged vertically side by side inside the mounting frame 109. Therefore, three sets are arranged in the height direction to realize the simultaneous dialysis process of soy sauce inside multiple dialysis bags 111. The soy sauce inside the dialysis bag 111 enters the output pipe 105 along the connecting hose 106 and is discharged. Therefore, the soy sauce moves slowly and continuously along the input pipe 104, dialysis bag 111 and output pipe 105 and is dialyzed. A concentration sensor is installed inside the output pipe 105. The concentration sensor is used to detect the ion concentration value in the soy sauce after dialysis.

[0030] The inlet pipe 107 is connected to the upper side wall of the bottom tank 101 near the outlet pipe 105. Deionized water enters the bottom tank 101 along the inlet pipe 107. Since the deionized water contains no ions, the concentration of deionized water inside the bottom tank 101 is lower than the concentration of soy sauce inside the dialysis bag 111. Sodium and chloride ions inside the dialysis bag 111 will pass through the dialysis bag 111 into the deionized water inside the bottom tank 101 to complete the dialysis process. The recovery pipe 108 is connected to the lower side wall of the bottom tank 101 near the inlet pipe 104. The deionized water inside the bottom tank 101 enters the bottom tank 101 along the recovery pipe 107. 8. The flow direction of deionized water inside the bottom box 101 is opposite to the flow direction of soy sauce inside the dialysis bag 111. The flow rate of deionized water along the inlet pipe 107, bottom box 101 and recovery pipe 108 matches the flow rate of soy sauce inside the dialysis bag 111, further achieving the required dialysis efficiency. The mounting frame 109 is fixedly connected inside the bottom box 101. Deionized water can flow along the mounting frame 109. The mounting frame 109 has multiple through holes 110 evenly opened inside. The sliding block 303 is movably connected inside the through holes 110, thereby realizing the required assembly process.

[0031] The clamping part 2 is movably connected to the housing part 1. The clamping part 2 includes an insertion tube 201 and an iron semi-ring 208 movably connected to the outer surface of the insertion tube 201. The insertion tube 201 is used to insert and fix the end of the dialysis bag 111. The retaining ring 202 is fixedly connected to the outer surface of the insertion tube 201 and is engaged with the side wall of the sliding block 303. The diameter of the retaining ring 202 is larger than the diameter of the insertion tube 201, which is used to limit the insertion depth of the insertion tube 201. The retaining ring 202 facilitates the insertion of the insertion tube 201. The appropriate depth value of the matching hole 304 is used to facilitate the subsequent installation and fixation of the dialysis bag 111; the hose clamp 204 is snapped and fixed to the outer surface of the ferrous semi-ring 208. The hose clamp 204 is mostly adjustable with torsion spring, and the end of the dialysis bag 111 is located between the ferrous semi-ring 208 and the hose clamp 204 to achieve snap-fit ​​fixation of the dialysis bag 111, that is, the end of the dialysis bag 111 is installed between the ferrous semi-ring 208 and the hose clamp 204, and the hose clamp 204 is tightened to make the hose clamp 204 snap-fit ​​and fix the end of the dialysis bag 111.

[0032] The guide section 3 is evenly distributed inside the housing section 1. The guide section 3 includes a positioning shell 301 and a sliding block 303 that slides inside the positioning shell 301. The matching hole 304 is opened inside the sliding block 303, and the inner wall of the matching hole 304 is provided with an internal thread. The outer surface of the end of the insertion tube 201 is provided with an external thread. The side of the insertion tube 201 away from the dialysis bag 111 is threadedly inserted and fixed to the matching hole 304. That is, before the dialysis bag 111 and the insertion tube 201 are clamped and fixed, the insertion tube 201 is first threadedly fixed to the matching hole 304, which further improves the installation convenience and efficiency of the desalination device.

[0033] In use, first, thread the multiple insertion tubes 201 into the corresponding matching holes 304. At the same time, insert the dialysis bags 111 into the outer surfaces of the insertion tubes 201 on opposite sides. Use the hose clamps 204 to snap and fix the ends of the dialysis bags 111 and the ferrous semi-rings 208. Meanwhile, the outer surfaces of the insertion tubes 201 on opposite sides are also snapped and fixed with the connecting hoses 106. Finally, combine the box cover 102 with the sealing cover of the bottom box 101 to complete the assembly process.

[0034] Soy sauce is then slowly introduced through the inlet pipe 104. The soy sauce then slowly enters the dialysis bag 111 through the connecting hose 106. At the same time, deionized water is continuously introduced into the bottom tank 101 through the water inlet pipe 107. The deionized water passes through the mounting bracket 109 and then dialyzes with the soy sauce inside the dialysis bag 111. The flow direction of the soy sauce inside the dialysis bag 111 is opposite to the flow direction of the deionized water inside the bottom tank 101, thereby effectively increasing the contact area and contact time between the deionized water and the soy sauce, thus ensuring the dialysis effect.

[0035] During dialysis, the 100 Dalton (Da) regenerated cellulose (RC) membrane in dialysis bag 111, with its symmetrical pore distribution, can selectively retain amino acids and macromolecular flavor substances in soy sauce, while allowing salts (Na⁺, Cl⁻, etc.) to diffuse freely into deionized water. By regularly replacing the dialysis solution, the salt content in soy sauce can be effectively reduced.

[0036] At the end of the desalination process, deionized water is replaced with an amino acid solution to replenish flavor substances that may be lost during dialysis, thus achieving the dual effect of efficient desalination and flavor preservation. The operation is simple and suitable for industrial production.

[0037] The deionized water inside the bottom tank 101 flows continuously and is eventually discharged along the recovery pipe 108. The deionized water circulates inside the bottom tank 101, thereby improving the dialysis effect on the soy sauce inside the dialysis bag 111. The soy sauce inside the dialysis bag 111 flows slowly and is continuously discharged along the output pipe 105. The concentration sensor inside the output pipe 105 detects the concentration value of ions inside the discharged soy sauce, further achieving the desired flow dialysis effect.

[0038] Second Embodiment like Figures 4 to 9 As shown, when dialyzing the soy sauce inside the dialysis bag 111 according to the above embodiment, the soy sauce flows slowly inside the dialysis bag 111, and the dialysis bag 111 is mostly cylindrical. Therefore, the soy sauce on the periphery of the dialysis bag 111 has a large contact area with deionized water and the dialysis effect is good. However, the soy sauce located in the center of the dialysis bag 111 cannot fully contact the deionized water inside the bottom chamber 101 for dialysis, and the dialysis bag 111 is easily blocked by substances in the soy sauce, affecting the normal discharge of subsequent ions and further reducing the dialysis effect of the subsequent soy sauce. At the same time, ions in the soy sauce enter the bottom chamber along the dialysis bag 111. Inside the deionized water tank 101, the ions continuously fall and settle at the bottom of the tank 101 due to gravity. This results in different ion concentrations at different depths within the deionized water tank 101, affecting the dialysis efficiency of the deionized water on the soy sauce inside the dialysis bags 111 at different heights. Furthermore, when the ion concentration of the soy sauce entering the dialysis bag 111 through the input pipe 104 or exiting the soy sauce through the output pipe 105 changes, existing technologies cannot adaptively adjust the dialysis effect on the soy sauce inside the dialysis bag 111, thus affecting the quality of the subsequently recovered soy sauce.

[0039] To address the aforementioned issues, the soy sauce desalination device based on dialysis technology further includes: a positioning shell 301 fixedly connected to the bottom of the through hole 110, so the position of the positioning shell 301 will not change; and when the ion concentration of the soy sauce inside the dialysis bag 111 increases, the sliding block 303 drives the dialysis bag 111 to move up and down by an increased amount, further achieving adaptive adjustment of the dialysis effect based on the ion concentration inside the soy sauce.

[0040] The telescopic component 302 is fixedly connected inside the positioning shell 301, and the top output end of the telescopic component 302 is fixedly connected to the bottom of the sliding block 303. It is used to drive the sliding block 303 to move up and down along the through hole 110. The telescopic component 302 can use a multi-stage pneumatic push rod. The output end of the telescopic component 302 can drive the sliding block 303 to move up and down inside the positioning shell 301, thereby adjusting the moving height of the sliding block 303 inside the positioning shell 301.

[0041] The horizontal plate 305 is fixedly connected between two adjacent sliding blocks 303. When the sliding blocks 303 move up and down, they drive the horizontal plate 305 to move up and down. The horizontal plate 305 is used to connect two sliding blocks 303 on the same side. Both the horizontal plate 305 and the sliding blocks 303 are provided with sealing rings on their outer surfaces. The sealing rings elastically seal and slide against the inner wall of the positioning shell 301, ensuring that the deionized water inside the positioning shell 301 can only be continuously discharged along the top hole 308. That is, when the telescopic member 302 drives the sliding block 303 to move up and down, the sliding block 303 synchronously drives the horizontal plate 305 between the two to move up and down.

[0042] Bottom holes 306 are evenly distributed inside the positioning shell 301, and a one-way inlet valve 307 is installed inside the bottom hole 306. Deionized water inside the bottom tank 101 enters the positioning shell 301 one-way upwards along the one-way inlet valve 307 inside the bottom hole 306. This arrangement further achieves the upward flow effect of deionized water inside the bottom tank 101, preventing ions inside the deionized water from continuously settling downwards under their own weight. Top holes 308 are evenly distributed inside the horizontal plate 305, and the top of the top hole 308 is connected to the support rod 4. The bottom is matched, and a one-way liquid outlet valve 309 is set inside the top hole 308. The deionized water inside the positioning shell 301 is discharged upward in one direction along the one-way liquid outlet valve 309 inside the top hole 308. The deionized water discharged along the top hole 308 continuously impacts the bottom of the dialysis bag 111, further improving the flow and dialysis effect of the deionized water and the soy sauce inside the dialysis bag 111. This avoids the problem of slow flow of soy sauce inside the dialysis bag 111 for a long time and uneven internal dialysis, which would affect the dialysis effect.

[0043] The pressing part 4 is fixedly connected inside the housing part 1. The pressing part 4 includes a support rod 401 and a moving block 404 movably connected to both sides of the support rod 401. The side walls of the support rod 401 are fixedly connected to the inner wall of the mounting frame 109, so the position of the support rod 401 remains fixed. When the sliding block 303 drives the dialysis bag 111 to move up and down, the bottom of the dialysis bag 111 continuously presses against the top of the support rod 401, thereby squeezing and flowing the soy sauce inside the dialysis bag 111, avoiding the soy sauce from flowing slowly for a long time and affecting its dialysis effect with deionized water. When the up and down movement of the dialysis bag 111 increases, the amount of squeezing between it and the support rod 401 increases. The moving block 404 moves along both sides of the support rod 401 and pushes and stirs the soy sauce inside the dialysis bag 111, improving the fluidity and mixing effect of the soy sauce inside the dialysis bag 111.

[0044] The receiving hole 402 is located inside the support rod 401. The bottom of the receiving hole 402 corresponds to the top of the top hole 308, and its diameter is smaller than that of the top hole 308. It is used for the upward flow of deionized water. Therefore, when the deionized water inside the top hole 308 is discharged upward, some of the deionized water enters the receiving hole 402 and flows. The resetting member 403 is symmetrically arranged on both sides of the support rod 401, and its other end is fixedly connected to the side wall of the moving block 404. The resetting member 403 can be a corrugated pipe structure. The top two sides of the receiving hole 402 are connected to the interior of the resetting member 403. Part of the deionized water discharged upward from the top hole 308 enters the interior of the resetting member 403 along the receiving hole 402. The amount of deionized water inside the resetting member 403 increases, which drives the moving block 404 to move away from the support rod 401. At the same time, the bottom of the dialysis bag 111 and the top of the moving block 404 press against each other, thereby realizing the pushing and mixing effect of the moving block 404 on the soy sauce inside the dialysis bag 111.

[0045] Therefore, in actual use, soy sauce flows inside the dialysis bag 111, while deionized water flows inside the bottom box 101. The soy sauce continuously flows with the deionized water along the dialysis bag 111, thereby continuously reducing the ion concentration of the soy sauce. At the same time, the telescopic component 302 drives the sliding block 303 to move up and down repeatedly inside the positioning shell 301. The sliding block 303 drives the dialysis bag 111 to move up and down through the insertion pipe 201. The dialysis bag 111 causes the soy sauce inside to shake up and down, improving the uniformity of contact between the soy sauce and the deionized water. The bottom of the dialysis bag 111 continuously presses against the top of the support rod 401. Under this pressure, the dialysis bag 111 undergoes elastic deformation and applies pressure to the soy sauce inside. The soy sauce inside the dialysis bag 111 continuously flows and mixes, further improving the fluidity and mixing of the soy sauce, avoiding problems such as slow flow over a long period of time and uneven dialysis.

[0046] Simultaneously, when the sliding block 303 moves downward, it synchronously drives the horizontal plate 305 to move downward along the positioning shell 301. The deionized water inside the positioning shell 301 is squeezed and discharged upward in one direction along the one-way discharge valve 309 inside the top hole 308. The deionized water continuously flows upward and impacts the bottom of the dialysis bag 111, causing the deionized water to mix and impact the soy sauce inside the dialysis bag 111, further improving the mixing and dialysis effect of the soy sauce and deionized water inside the dialysis bag 111. Furthermore, by using the impact of the deionized water on the outer surface of the dialysis bag 111 and the up-and-down vibration of the dialysis bag 111 itself, the substances blocking the inside of the dialysis bag 111 are effectively cleared by vibration and impact, preventing the dialysis bag 111 from becoming blocked and affecting the normal dialysis discharge of ions in the subsequent deionized water.

[0047] Simultaneously, the upward-flowing deionized water enters the reset member 403 through the receiving hole 402, causing the volume of the reset member 403 to increase and drive the moving blocks 404 on both sides to move away from the support rod 401. The moving blocks 404 continuously apply a lateral pushing force to the bottom of the dialysis bag 111, and together with the sliding block 303, drive the vertical compression of the dialysis bag 111 with the support rod 401 and the moving block 404, as well as the upward flow impact of the deionized water, effectively improving the flow and mixing effect of the soy sauce inside the dialysis bag 111, avoiding its slow flow for a long time and affecting its uniform dialysis effect with the deionized water.

[0048] Subsequently, when the telescopic component 302 drives the sliding block 303 to move upward, the sliding block 303 simultaneously drives the horizontal plate 305 to move upward along the positioning shell 301. As a result, the internal volume of the positioning shell 301 increases and the pressure decreases. Under the negative pressure inside the positioning shell 301, the deionized water inside the bottom box 101 is drawn in through the one-way inlet valve 307 inside the bottom hole 306 and stored inside the positioning shell 301. This facilitates the subsequent downward movement of the sliding block 303 and the horizontal plate 305, allowing the deionized water inside the positioning shell 301 to be discharged upward through the one-way outlet valve 309 inside the top hole 308. At the same time, the deionized water inside the bottom box 101 moves upward repeatedly under the suction force inside the positioning shell 301, thereby achieving upward mixing and flow of the deionized water inside the bottom box 101. This effectively prevents ions from precipitating inside the deionized water due to their own weight and affecting the dialysis effect of dialysis bags 111 of different heights, ensuring the uniformity and efficiency of dialysis.

[0049] When the concentration sensor inside the output pipe 105 detects that the ion concentration inside the soy sauce is greater than the preset concentration value, the output end of the telescopic component 302 drives the sliding block 303 to move up and down accordingly. Then, the sliding block 303 drives the dialysis bag 111 to move up and down more through the insertion pipe 201. The pressure between the bottom of the dialysis bag 111 and the bottom of the support rod 401 and the moving block 404 increases. Under the action of this pressure, the flow distance of the soy sauce inside the dialysis bag 111 increases, further improving the flow and mixing effect of the soy sauce inside the dialysis bag 111, and correspondingly increasing the dialysis mixing effect of the soy sauce and the deionized water inside the bottom box 101.

[0050] Simultaneously, the sliding block 303 causes the horizontal plate 305 to move up and down along the positioning shell 301, increasing the amount of deionized water discharged upwards through the one-way outlet valve 309 inside the top hole 308. This increases the flow impact force exerted by the deionized water on the bottom of the dialysis bag 111, further improving the dialysis effect of mixing deionized water and soy sauce. Furthermore, the amount of deionized water entering the reset member 403 through the receiving hole 402 increases, causing the reset member 403 to move the moving block 404 further away from the support rod 401. This increases the lateral thrust exerted by the moving block 404 on the bottom of the dialysis bag 111. This further improves the mixing effect of the soy sauce inside the dialysis bag 111. When the sliding block 303 drives the horizontal plate 305 to move upward along the positioning shell 301, the change in volume inside the positioning shell 301 increases, and the amount of deionized water inside the bottom box 101 entering the positioning shell 301 through the one-way inlet valve 307 inside the bottom hole 306 increases. Under the action of this suction force, the fluidity of the deionized water inside the bottom box 101 increases, further improving the upward flow and mixing effect of the deionized water, and avoiding an increase in the amount of ion precipitation in the deionized water and affecting the uniform dialysis effect of the soy sauce inside the dialysis bag 111.

[0051] Third Embodiment When dialysis of the soy sauce inside the dialysis bag 111 is performed according to the above embodiment, the sliding block 303 continuously drives the dialysis bag 111 to move up and down and presses against the support rod 401 and the moving block 404. As a result, the tensile force on both ends of the dialysis bag 111 increases and it is easy to detach from the hose clamp 204 and the ferrous semi-ring 208, thereby reducing the assembly sealing of the insertion pipe 201 and the dialysis bag 111. At the same time, if the dialysis bag 111 at a certain position cannot perform dialysis of the soy sauce inside due to its own reasons, the operator needs to stop the machine to replace it, which will affect the normal dialysis work of the other dialysis bags 111 and reduce the dialysis efficiency.

[0052] To address the aforementioned issues, the soy sauce desalination device based on dialysis technology further includes: an elastic block 203, symmetrically fixedly connected to the sidewall of the ferrous semi-ring 208, with the ferrous semi-ring 208 located on the upper and lower sides. The elastic block 203 is elastic, positioned on the front and rear sides with its two ends fixedly connected to the facing end faces of the two ferrous semi-rings 208 respectively. When the ferrous ring plate 208 moves on the outer surface of the conical sleeve 206, it simultaneously stretches the elastic block 203, causing elastic deformation, thereby increasing the squeezing force of the ferrous semi-ring 208 on the inner wall of the end of the dialysis bag 111. The outer surface of the sleeve 206 moves laterally, and the multiple moving blocks 404 located near the sliding block 303 are magnetic, and the ferromagnetic half ring 208 is ferromagnetic. There is a magnetic attraction between the ferromagnetic half ring 208 and the moving blocks 404. When the insertion tube 201 drives the ferromagnetic half ring 208 to move downward by an increased amount, the magnetic attraction applied by the moving blocks 404 to the ferromagnetic half ring 208 increases, and the amount of movement of the ferromagnetic half ring 208 away from the sliding block 303 increases. Thus, the lateral movement of the ferromagnetic half ring 208 on the outer surface of the insertion tube 201 is achieved by the magnetic attraction applied by the moving blocks 404 at both ends.

[0053] A conical sleeve 206 is fitted onto the outer surface of the insertion tube 201. The diameter of the conical sleeve 206 gradually increases from one end of the sliding block 303 to the other end. The inner wall of the ferrous ring plate 208 is elastically slidably connected to the outer surface of the conical sleeve 206. When the ferrous semi-ring 208 drives the elastic block 203 to move away from the sliding block 303, the squeezing force between the ferrous ring plate 208 and the conical sleeve 206 increases, and the elastic squeezing force applied to the dialysis bag 111 by the ferrous semi-ring 208 increases, further improving the clamping effect of the ferrous semi-ring 208 and the hose clamp 204 on the dialysis bag 111.

[0054] The limiting guide ring 207 is fixedly connected to the end of the insertion tube 201 away from the sliding block 303. It is used to guide the soy sauce inside the dialysis bag 111 into the insertion tube 201. After the soy sauce inside the dialysis bag 111 reaches the position of the limiting guide ring 207, it enters the insertion tube 201 under its guidance. A buffer part 205 is provided between the limiting guide ring 207 and the ferrous ring plate 208 and on the outer surface of the insertion tube 201. The buffer part 205 is elastic. The buffer part 205 can be a spring structure and is located on the outer surface of the conical sleeve 206. The elastic buffering effect of the buffer part 205 realizes the elastic reset effect of the ferrous semi-ring 208.

[0055] During the above-described usage, when the output end of the telescopic component 302 drives the sliding block 303 to move downward along the positioning shell 301, the sliding block 303 simultaneously drives the internal insertion tube 201 and dialysis bag 111 to move downward. At this time, the bottom of the dialysis bag 111 is pressed against the support rod 401 and the moving block 404, and the insertion tube 201 drives the ferrous semi-ring 208 on the outer surface to move downward. The height difference between the ferrous semi-ring 208 and the moving block 404 continuously decreases, and when the sliding block 303 moves downward, it drives the horizontal plate 305 to move downward along the positioning shell 301. 1. The interior moves downward, and the deionized water inside the positioning shell 301 is discharged upward through the one-way outlet valve 309 inside the top hole 308. The deionized water part enters the reset member 403 through the receiving hole 402 and drives the moving block 404 to move away from the support rod 401. The lateral distance between the moving block 404 at both ends and the ferrous half ring 208 decreases. Therefore, the magnetic attraction force applied by the moving block 404 at both ends to the ferrous ring plate 208 under its own magnetic action increases, and the ferrous half ring 208 moves away from the sliding block 303 at the same time.

[0056] During the movement of the ferrous ring plate 208, the hose clamp 204 synchronously drives the end of the dialysis bag 111 to move away from the sliding block 303. Therefore, the two sides of the dialysis bag 111 move towards the center of each other, thus effectively preventing the end of the dialysis bag 111 from separating from the hose clamp 204 when it is squeezed and contacted with the support rod 401 and the moving block 404, which would affect the normal flow of soy sauce inside. Furthermore, when the end of the dialysis bag 111 moves laterally on the outer surface of the insertion tube 201, the squeezing contact position between its inner wall and the limiting guide ring 207 is adjusted accordingly. This achieves compensation for the flow position of soy sauce when the dialysis bag 111 is squeezed and deformed by the support rod 401 and the moving block 404, preventing damage to the structure of the soy sauce inside the dialysis bag 111 after being squeezed. It also has a scraping and cleaning effect on the soy sauce that is blocked at the contact position between the limiting guide ring 207 and the dialysis bag 111, improving the internal fluidity and smoothness of the soy sauce.

[0057] Simultaneously, as the iron semi-ring 208 and the hose clamp 204 move the end of the dialysis bag 111 away from the sliding block 303, the diameter of the conical sleeve 206 gradually increases from the end of the sliding block 303 to the other end. The iron semi-ring 208 simultaneously squeezes the conical sleeve 206 to move away from the sliding block 303. As a result, the iron semi-rings 208 on both sides continuously stretch the elastic block 203 and move it away from the insertion pipe 201. Since the hose clamp 204 is engaged with the outer surface of the dialysis bag 111 and its diameter remains unchanged, the iron semi-ring 208 applies increased squeezing force to the inner diameter of the end of the dialysis bag 111. This further ensures the pressing effect of the end of the dialysis bag 111 with the iron semi-ring 208 and the hose clamp 204 when it moves downward and deforms due to mutual squeezing and contact with the support rod 401 and the moving block 404. This prevents the dialysis bag 111 from detaching and affecting the normal flow of the soy sauce inside.

[0058] Subsequently, when the telescopic component 302 drives the sliding block 303 to move upward along the positioning shell 301, the sliding block 303 simultaneously drives the insertion pipe 201 to move upward. The height between the ferrous semi-ring 208 and the moving block 404 decreases. At the same time, the deionized water inside the positioning shell 301 cannot be discharged through the one-way outlet valve 309 inside the top hole 308. Under the elastic force of the reset component 403, the moving block 404 moves towards the end closer to the support rod 401 to the initial position. The lateral distance between the moving blocks 404 at both ends and the ferrous semi-ring 208 increases. Therefore... As the distance between the ferrous semi-ring 208 and the moving block 404 increases and the magnetism decreases, the ferrous semi-ring 208 moves in the opposite direction to return to its original position under the elastic force of the buffer part 205. The ferrous semi-ring 208 moves the end of the dialysis bag 111 towards the sliding block 303 to the initial distance through the hose clamp 204. The insertion tube 201 still stretches and tightens the dialysis bag 111. At the same time, the squeezing force between the ferrous semi-ring 208 and the conical sleeve 206 decreases and returns to the initial value. The squeezing force of the ferrous semi-ring 208 and the hose clamp 204 on the end of the dialysis bag 111 returns to the initial value.

[0059] When the concentration value detected by the concentration sensor inside the output tube 105 is greater than the set maximum concentration value, it indicates that the dialysis bag 111 at that location has lost its dialysis function due to its own reasons. If all of them are stopped and replaced at this time, the overall dialysis efficiency will be reduced. Therefore, the telescopic component 302 is activated and the output end is shortened to the maximum distance. The output end of the telescopic component 302 drives the sliding block 303 to move downward along the positioning shell 301 to the maximum distance. The sliding block 303 simultaneously drives the insertion tube 201 and the dialysis bag 111 to move downward to the maximum distance. At this time, the pressure contact between the bottom of the dialysis bag 111 and the support rod 401 reaches the maximum value, thereby causing the dialysis bag 111 to contact each other and seal and close. Soy sauce no longer flows inside the dialysis bag 111, thus allowing other dialysis bags 111 to continue to work normally and ensure dialysis efficiency.

[0060] Simultaneously, after the sliding block 303 moves downward to its maximum distance and stops moving, the sliding block 303 synchronously drives the horizontal plate 305 to move downward along the positioning shell 301 to its maximum distance and stops moving. The deionized water inside the positioning shell 301 no longer discharges through the one-way outlet valve 309 inside the top hole 308. The moving block 404 is in its initial position, but the insertion pipe 201 drives the ferrous semi-ring 208 to move downward to its maximum distance and is laterally aligned with the moving block 404. Therefore, the magnetic attraction force applied by the moving blocks 404 at both ends to the ferrous semi-ring 208 causes the ferrous semi-ring 208 to... When ring 208 moves to the maximum distance away from sliding block 303, the ferrous semi-ring 208 stretches elastic block 203 and presses against tapered sleeve 206. Then, the clamping force applied to the end of dialysis bag 111 by hose clamp 204 reaches its maximum value, further ensuring the clamping effect of both ends of dialysis bag 111 when support rod 401 squeezes and blocks dialysis bag 111. This avoids excessive tension on both sides of dialysis bag 111 and prevents it from separating from ferrous semi-ring 208 and hose clamp 204, affecting the internal sealing of soy sauce.

[0061] After all the dialysis bags 111 have completed dialysis of the soy sauce, open the lid 102 and replace the dialysis bags 111. Repeat the above process to dialyze the soy sauce in the future.

[0062] Example 4 The desalination method of the soy sauce desalination device based on dialysis technology as described in the above embodiments includes the following steps: S1. Both ends of the dialysis bag 111 are sleeved on the outer surface of the insertion tube 201. The flow direction of the soy sauce inside the dialysis bag 111 is opposite to the flow direction of the deionized water on the outer surface of the dialysis bag 111. The ion dialysis of the soy sauce inside the dialysis bag 111 is discharged into the deionized water.

[0063] S2. When the ion concentration inside the dialysis bag 111 increases, the sliding block 303 causes the dialysis bag 111 to move up and down inside the positioning shell 301, increasing the squeezing pressure between the dialysis bag 111, the support rod 401, and the moving block 404. This increases the mixing and stirring degree of the soy sauce inside the dialysis bag 111, increases the upward flow efficiency of deionized water, and increases the movement of the moving block 404 away from the support rod 401, thus increasing the lateral thrust on the soy sauce inside the dialysis bag 111.

[0064] S3. When the downward movement of the dialysis bag 111 increases, the iron semi-ring 208 causes the end of the dialysis bag 111 to move further away from the sliding block 303 along the insertion tube 201, and the squeezing force exerted by the iron semi-ring 208 on the inner wall of the dialysis bag 111 increases.

[0065] S4. When the ion concentration inside the dialysis bag 111 reaches its maximum value, the sliding block 303 drives the dialysis bag 111 to move downward to the maximum distance. The bottom of the dialysis bag 111 is pressed and blocked by the top of the support rod 401. Soy sauce no longer flows inside the dialysis bag 111. The iron semi-ring 208 drives the end of the dialysis bag 111 to move away from the sliding block 303 to the maximum distance and presses it to the limit.
