Description

Technical Field

[0001] This disclosure relates to the field of product preservation technology, and in particular to a preservation system, an ion concentration regulation system, and a cold storage. Background Technology

[0002] Maintaining a suitable water quality environment is crucial for ensuring the survival rate of aquatic products during transportation and storage. Depending on the type of water body, aquatic products can be divided into freshwater products and products requiring preservation. These two types differ significantly in their physiological characteristics and environmental adaptability, leading to different requirements for water quality control during preservation.

[0003] Freshwater aquatic products are primarily adapted to low-salinity environments (typically below 0.5‰), and their osmotic pressure regulation mechanism mainly focuses on preventing salt loss. Therefore, in the process of keeping freshwater aquatic products alive, the key is to maintain water cleanliness, control the concentration of ammonia nitrogen and carbon dioxide in the water, maintain a suitable dissolved oxygen level, and control water temperature. The need for salinity regulation is relatively low, and it mainly focuses on preventing abnormal increases in salinity.

[0004] In contrast, products requiring preservation live in environments with high salinity (typically 10–35‰), and their physiological structures and osmotic pressure regulation mechanisms are adapted to this environment. During transportation and preservation, these products are extremely sensitive to changes in salinity; excessively high or low salinity can cause osmotic imbalance, leading to physiological dysfunction and even death. Different types of products require preservation also exhibit significant differences in their salinity tolerance. Therefore, dynamic regulation and stable control of salinity are crucial factors in the preservation system for these products.

[0005] Currently, salinity control systems for preserving products mostly employ reverse osmosis or freshwater dilution for desalination. However, these methods suffer from high energy consumption, slow response, irreversible desalination processes, and large fluctuations in water quality, which can easily lead to secondary pollution, affect water quality stability, and consequently impact the preservation effect of the products.

This achieves bidirectional and dynamic adjustment of the ion concentration of the salt solution, suitable for various marine aquatic products and new products to be preserved. For example, when the initial salt solution ion concentration is low, the capacitive deionization unit can actively increase the solution concentration to the target range through the ion desorption mechanism, which contrasts sharply with the limitation of traditional reverse osmosis methods, which can only reduce salinity. This reversible adjustment capability allows the system to flexibly respond to situations where the initial salt solution concentration is too high or too low, without the need for additional high-concentration brine or large amounts of fresh water for dilution, thus significantly reducing operational complexity and resource consumption. Furthermore, capacitive deionization technology itself features rapid response, enabling quick adjustments to the ion adsorption or desorption process based on real-time monitoring results. This ensures that the ion concentration of the salt solution within the survival unit remains within the precise range required for the product to be survived, effectively solving the problem of slow response in traditional methods and providing a more stable and suitable survival environment for the product. In short, this disclosure, by introducing a capacitive deionization unit, achieves breakthroughs in energy efficiency, water quality stability, intelligence, and multifunctional adaptability, improving the energy efficiency, intelligence level, and applicability of the survival system, as well as increasing the survival rate and the system's greenness.

[0033] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification.

[0034] To address the problems of high energy consumption, slow response speed, irreversible desalination process, and large water quality fluctuations in the preservation of products in existing technologies, which can easily cause secondary pollution, affect water quality stability, and thus affect the preservation effect of products, this disclosure provides a preservation system, an ion concentration adjustment system, and a cold storage.

[0035] In this disclosure, a capacitive deionization unit is introduced into the preservation system. A salt solution supply unit provides the initial salt solution to the capacitive deionization unit. The capacitive deionization unit adjusts the ion concentration of the initial salt solution to the target ion concentration range required for the product to be preserved, and then provides the salt solution within the target ion concentration range to the preservation unit, thereby achieving a good preservation effect on the product to be preserved (e.g., marine aquatic products). The capacitive deionization unit, based on the principle of electroadsorption, can achieve controllable removal and release of salt under low voltage. For example, the "desalination" and "salting" functions are achieved through electrode reversal of the capacitive deionization unit, enabling precise adjustment under different salinity requirements. This achieves bidirectional and dynamic adjustment of the salt solution ion concentration, suitable for various applications of marine aquatic products and novel products to be preserved. For instance, when the initial salt solution ion concentration is low, the capacitive deionization unit can actively increase the solution concentration to the target range through ion desorption, which contrasts sharply with the limitation of traditional reverse osmosis methods, which can only reduce salinity. This reversible adjustment capability allows the system to flexibly respond to situations where the initial salt solution concentration is too high or too low, without the need for additional high-concentration brine or large amounts of fresh water for dilution, thus significantly reducing operational complexity and resource consumption. Furthermore, capacitive deionization technology itself features rapid response, enabling quick adjustments to the ion adsorption or desorption process based on real-time monitoring results. This ensures that the ion concentration of the salt solution within the survival unit remains within the precise range required for the product to be survived, effectively solving the problem of slow response in traditional methods and providing a more stable and suitable survival environment for the product. In short, this disclosure, by introducing a capacitive deionization unit, achieves breakthroughs in energy efficiency, water quality stability, intelligence, and multifunctional adaptability, improving the energy efficiency, intelligence level, and applicability of the survival system, as well as increasing the survival rate and the system's greenness.

[0036] In one exemplary embodiment, reference Figure 1 or Figure 2As shown, an ion concentration regulation system, a survival system, and a cold storage are provided. The ion concentration regulation system may include a brine solution supply unit 1 and a capacitor deionization unit 2. The survival system may include the aforementioned ion concentration regulation system and a survival unit 4. The survival unit 4 is used to store the product to be survived. That is, the survival unit 4 refers to the area or container in the system directly used to store or contain the product to be survived. This unit is the actual environment in which the product to be survived is located, and its internal environmental parameters (such as salinity, temperature, etc.) directly affect the survival status of the product. The survival unit 4 can be a simple container, such as an open water tank or a closed storage box, with sufficient internal space to contain the product to be survived. For example, for products that require an aquatic environment for survival, the survival unit 4 can be a pool filled with liquid; for products that require a humid environment but are not completely submerged for survival, the survival unit 4 can be a box with humidity control function. This unit ensures that the product to be survived is properly placed in a controlled environment, providing a basis for subsequent brine solution regulation. The products to be preserved may include, for example, marine aquatic products, or other products that require salt solutions of appropriate ion concentrations to be preserved; there are no limitations on this.

[0037] The salt solution providing unit 1 refers to the component in the system responsible for preparing or transporting liquids containing dissolved salts. The function of this unit is to provide the base liquid for subsequent ion concentration adjustment processes, ensuring that the system has the initial medium for adjustment.

[0038] The capacitive deionization unit 2 is a device that utilizes electrochemical principles to adsorb or desorb ions from a solution via electrodes. This unit can dynamically increase or decrease the ion concentration of the salt solution as needed, achieving precise control of water salinity. Specifically, the capacitive deionization unit 2 is configured to adjust the ion concentration of the initial salt solution to the target ion concentration range required to maintain the product. Capacitive deionization technology applies a voltage between the electrodes, causing ions in the solution to adsorb onto the electrode surface, thereby reducing the ion concentration of the solution; or, through the reverse operation, desorbing the adsorbed ions, thereby increasing the ion concentration of the solution. For example, when the ion concentration of the initial salt solution is higher than the target range, the capacitive deionization unit 2 can adsorb excess ions, reducing the solution concentration. Conversely, when the ion concentration of the initial salt solution is lower than the target range, the capacitive deionization unit 2 can release pre-adsorbed ions, increasing the solution concentration. This adjustment method is reversible, allowing for flexible adjustment of the ion concentration of the salt solution.

[0039] The salt solution providing unit 1 provides an initial salt solution to the capacitor deionization unit 2. The initial salt solution refers to the salt solution output from the salt solution providing unit 1 before entering the capacitor deionization unit 2 for ion concentration adjustment. Its ion concentration may be higher, lower, or close to the target ion concentration range required by the product to be kept alive. The capacitor deionization unit adjusts the ion concentration of the initial salt solution to the target ion concentration range required by the product to be kept alive, and then provides the salt solution within the target ion concentration range to the keeping unit 4 for use. The target ion concentration range refers to the range of salt solution ion concentrations necessary for the product to maintain its normal physiological activity and survival rate during the keeping process. This range is typically determined based on the type and physiological characteristics of the product to be kept alive.

[0040] One method of supplying the solution is to deliver the conditioned salt solution to the survival unit 4 via a pipeline and pump system, ensuring that the salinity of the environment within the survival unit 4 meets the requirements of the product to be preserved. For example, a simple pipeline can be installed, and a conventional liquid pump can be used to pump the conditioned salt solution from the capacitor deionization unit 2 to the survival unit 4. Alternatively, in some cases, if the capacitor deionization unit 2 is located above the survival unit 4, the conditioned salt solution can be directly introduced into the survival unit 4 by gravity. In this way, the product to be preserved can be continuously kept in a suitable salinity environment, thereby ensuring its survival rate.

[0041] For example, the capacitor deionization unit can be connected to the keep-alive unit 4 via a pipeline (referred to as the fifth pipeline). An ion concentration detection device, referred to as the third ion concentration detection device 30, is installed within the fifth pipeline. The third ion concentration detection device 30 is used to detect the ion concentration of the salt solution transferred from the capacitor deionization unit 2 to the keep-alive unit 4.

[0042] The fifth pipeline can be made of corrosion-resistant materials, such as polyvinyl chloride (PVC), polyethylene (PE), or stainless steel, to ensure the purity and stability of the brine solution during transmission. Furthermore, the fifth pipeline can integrate flow control valves or pumps to precisely control the flow rate and volume of the brine solution, ensuring stable and efficient delivery of the solution from the capacitor deionization unit 2 to the keep-alive unit 4.

[0043] The third ion concentration detection device 30 can be a conductivity sensor that indirectly reflects ion concentration by measuring the conductivity of the solution. It typically consists of one or more pairs of electrodes, and the conductivity between the electrodes changes with the ion concentration as the solution flows through it. Alternatively, the third ion concentration detection device 30 can also be an ion-selective electrode (ISE) sensor, such as an electrode specifically designed to detect specific ions like sodium, chloride, or calcium ions, thereby providing more accurate ion concentration data.

[0044] The core function of the third ion concentration detection device 30 is to measure the ion concentration of the salt solution in real time and accurately as it flows from the capacitive deionization unit 2 to the retention unit 4. This detection device continuously collects ion concentration data and transmits it to a control system. The control system compares the detected values ​​with a preset target ion concentration range; if a deviation is detected, it triggers an alarm or a corresponding adjustment mechanism. Furthermore, this detection device can form a closed-loop control with the control logic of the capacitive deionization unit 2. When the ion concentration deviates from the target range, the control system can instruct the capacitive deionization unit 2 to perform secondary adjustments or adjust its output parameters to ensure that the concentration of the salt solution entering the retention unit 4 always meets the requirements.

[0045] It should be noted that after the capacitive deionization unit 2 adjusts the ion concentration of the initial salt solution to the target ion concentration range required for the product to be kept alive, the salt solution within this target ion concentration range is transferred to the keeping unit 4 via the fifth pipeline. To ensure the accuracy of the ion concentration of the salt solution transferred to the keeping unit 4, this application includes a third ion concentration detection device 30 within the fifth pipeline. This third ion concentration detection device 30 detects the ion concentration of the salt solution in real time as it flows from the capacitive deionization unit 2 to the keeping unit 4. In this way, the concentration of the salt solution output by the capacitive deionization unit 2 can be verified in real time, and any concentration deviations that may occur during transmission can be detected and corrected promptly. This allows the keeping unit 4 to receive a salt solution that accurately matches the target ion concentration range, effectively avoiding the problem of inaccurate solution concentration affecting the keeping effect of the product to be kept alive. Compared to relying solely on the output control of the capacitive deionization unit 2, adding a real-time detection step in the transmission path can more reliably ensure the stability of the kept-alive water quality and improve the accuracy and reliability of the entire keeping system.

[0046] In this embodiment, a capacitive deionization unit 2 is introduced into the preservation system. Based on the principle of electroadsorption, the capacitive deionization unit can achieve controllable removal and release of salt under low voltage. For example, the "desalination" and "salt addition" functions can be achieved by reversing the electrodes of the capacitive deionization unit. It can achieve precise adjustment under different salinity requirements, realizing bidirectional and dynamic adjustment of the salt solution ion concentration, which is suitable for various marine aquatic products and new products to be preserved. Moreover, this reversible adjustment capability allows the system to flexibly cope with situations where the initial salt solution concentration is too high or too low, without the need to introduce high-concentration brine or large amounts of fresh water for dilution, thus significantly reducing operational complexity and resource consumption. In addition, the capacitive deionization technology itself has the characteristic of fast response speed, which can quickly adjust the ion adsorption or desorption process according to real-time monitoring results, ensuring that the salt solution ion concentration in the preservation unit 4 is always maintained within the precise range required by the product to be preserved. This effectively solves the problem of slow response of traditional methods and provides a more stable and suitable preservation environment for the product to be preserved. That is, by introducing a capacitor deionization unit, this embodiment can achieve breakthroughs in energy efficiency, water quality stability, intelligence level and multi-functional adaptability, thereby improving the energy efficiency, intelligence level and applicability of the survival system, and improving the survival rate and greenness of the system.

[0047] Furthermore, when this embodiment is equipped with a third ion concentration detection device 30, the concentration change of the salt solution during transmission can be monitored in real time. This effectively solves the problem that the concentration change or deviation of the salt solution during transmission may lead to inaccurate solution concentration received by the survival unit 4, affecting the survival effect. This solution ensures that the salt solution entering the survival unit 4 is always within the target ion concentration range required by the product to be survived, significantly improving the stability and accuracy of the survival water quality, thereby guaranteeing the survival rate and health status of the product to be survived.

[0048] In one exemplary embodiment, reference Figure 1 or Figure 2 As shown, an ion concentration regulation system, a preservation system, and a cold storage are provided. In this embodiment, the salt solution providing unit 1 includes a first storage tank 11, a second storage tank 12, and a solution mixing device 13. The first storage tank 11 is used to store a first liquid, and the second storage tank 12 is used to store a second liquid. The ion concentration of the first liquid is greater than the target ion concentration range, that is, the ion concentration of the first liquid is higher than the maximum value in the target ion concentration range, and can be denoted as a high ion concentration liquid or a high salinity liquid, with an ion concentration of 1%-2%. The ion concentration of the second liquid is less than the target ion concentration range, that is, the ion concentration of the second liquid is lower than the minimum value in the target ion concentration range, and can be denoted as a low ion concentration liquid or a low salinity liquid. For example, fresh water can be used as a low salinity liquid, with an ion concentration of less than 0.05%.

[0049] The first liquid storage tank is connected to the solution mixing device 13 via a first pipeline, the second liquid storage tank is connected to the solution mixing device 13 via a second pipeline, and the solution mixing device 13 is connected to the capacitor deionization unit 2 via a third pipeline.

[0050] The solution mixing device 13 is used to mix the first liquid transported by the first pipeline and the second liquid transported by the second pipeline to form a preliminary mixture, which is then transported to the capacitive deionization unit 2 through the third pipeline. It should be noted that the first pipeline can be made of corrosion-resistant plastic or stainless steel and can be equipped with a flow meter and control valves to precisely control the delivery rate of the first liquid. The second pipeline can have the same or similar structure as the first pipeline, and there is no limitation thereto.

[0051] The structures of the first storage tank 11 and the second storage tank 12 can be the same or different, and there is no limitation on this. The above-mentioned storage tanks can be implemented in various forms. For example, it can be a sealed tank with a liquid level sensor and a liquid outlet valve to ensure liquid quality and precise control of liquid output; or it can be an open liquid storage pool, from which the liquid is extracted by a pumping system.

[0052] The solution mixing device 13 is a key component for achieving proportional mixing of two liquids. It can be a static mixer that uses internal guide vanes to ensure thorough mixing of the two liquids during flow; or it can be a dynamic mixer, such as a mixing tank with a stirring paddle, which achieves rapid and uniform mixing through mechanical stirring.

[0053] In some embodiments, the solution mixing device 13 can be a smart mixing valve. The user can manually set or automatically detect the product to be kept alive and determine its required target ion concentration range. Based on the required target ion concentration range, the first liquid in the first storage tank 11 and the second liquid in the second storage tank 12 are automatically retrieved and mixed to obtain a mixed liquid, which is a pre-mixed liquid. The ion concentration of this liquid is between that of the first and second liquids, and by adjusting the mixing ratio of the two liquids, its ion concentration can be initially approached to the target ion concentration range required for the product to be kept alive.

[0054] In this embodiment, by setting up two types of reserve liquids with high and low concentrations and pre-mixing them using the solution mixing device 13, a pre-mixed liquid with an ion concentration initially close to the target range can be quickly generated. This significantly reduces the workload and time required by the capacitive deionization unit 2 to adjust the ion concentration of the initial salt solution, thereby reducing system energy consumption and improving overall response speed. Furthermore, this combination of dual reserve tanks and the mixing device allows the system to flexibly adjust the concentration of the initial salt solution according to actual needs, avoiding the problem of excessive concentration deviation that may occur with traditional single initial salt solutions, thus improving water quality stability and providing a more suitable environment for the preservation of products.

[0055] In addition, in this embodiment, a first ion concentration detection device 10 is provided in the first pipeline, which is used to detect the ion concentration of the first liquid. A second ion concentration detection device 20 may be provided in the second pipeline, which is used to detect the ion concentration of the second liquid.

[0056] It should be noted that both the first ion concentration detection device 10 and the second ion concentration detection device 20 are sensors or devices used for real-time measurement of ion concentration in fluids, and their function is to provide real-time ion concentration data for the corresponding liquid. The specific types of the first ion concentration detection device 10 and the second ion concentration detection device 20 can be referenced to the third ion concentration detection device 30, and are not limited thereto.

[0057] In this embodiment, by installing a first ion concentration detection device 10 and a second ion concentration detection device 20 in the first and second pipelines of the salt solution supply unit 1, respectively, the problem of lacking real-time monitoring of liquid ion concentration during the mixing of the first and second liquids to form the initial mixed liquid is solved. Specifically, when the first liquid in the first storage tank 11 is transported through the first pipeline, the first ion concentration detection device 10 can detect its ion concentration in real time and feed this data back to the solution mixing device 13. At the same time, when the second liquid in the second storage tank 12 is transported through the second pipeline, the second ion concentration detection device 20 can also detect its ion concentration in real time and feed the data back to the solution mixing device 13. Based on these real-time ion concentration data, the solution mixing device 13 can accurately adjust the mixing ratio of the first and second liquids, which ensures that the ion concentration of the initial mixed liquid is more stable and accurate, significantly improving the accuracy and efficiency of the subsequent capacitor deionization unit 2 in adjusting the ion concentration, and effectively avoiding adjustment errors caused by initial concentration fluctuations. This precise premixing process significantly reduces the burden on the subsequent capacitive deionization unit 2 when adjusting the ion concentration, enabling it to more efficiently and accurately adjust the ion concentration of the salt solution to the target ion concentration range required for the product to be kept alive.

[0058] In one exemplary embodiment, reference Figure 1 As shown, an ion concentration regulation system, a preservation system, and a cold storage are provided. In this embodiment, the preservation system includes a waste liquid storage unit 4, which is connected to a capacitor deionization unit via a fourth pipeline. A one-way valve or an electric valve can be integrated into the fourth pipeline to control the flow direction of the waste liquid, prevent backflow, and allow for automatic or manual discharge control when needed.

[0059] When it is necessary to remove ions adsorbed by the capacitor deionization unit, the second storage chamber 12 transmits the second liquid to the capacitor deionization unit 2 through the second pipeline. After the ions desorbed by the capacitor deionization unit dissolve in the second liquid, they are discharged to the waste liquid storage unit 4 through the fourth pipeline.

[0060] Waste liquid storage unit 4 is a container used to collect and temporarily store waste liquids or solutions containing high concentrations of ions generated during system operation. Its main function is to isolate hazardous substances, preventing them from re-entering or contaminating the main circulation system, and to facilitate subsequent waste liquid treatment. This unit can be a stand-alone tank, such as a sealed container made of corrosion-resistant materials (e.g., polyethylene, polypropylene, or stainless steel) to ensure that waste liquid does not leak or evaporate. Alternatively, waste liquid storage unit 4 can be a modular design integrated with the system, such as a removable collection tank at the bottom of the system for easy periodic emptying and maintenance.

[0061] After adjusting the initial salt solution ion concentration to meet the requirements of the product to be kept alive, the capacitive deionization unit 2 adsorbs a large number of ions. To maintain the continuous and efficient operation of the capacitive deionization unit 2, periodic ion desorption and regeneration are necessary. In traditional methods, if the high-concentration ions desorbed are not properly handled, they can easily cause system pollution or water quality fluctuations. This application cleverly solves this problem by introducing a waste liquid storage unit 4 and a dedicated waste liquid discharge mechanism. Specifically, when the capacitive deionization unit 2 needs to perform ion desorption, the system uses a salt solution to provide the second storage chamber 12 in unit 1. The second storage chamber 12 stores a second liquid with an ion concentration lower than the target ion concentration range; this low-ion-concentration liquid is ideal as a rinsing medium during the desorption process. The second storage chamber 12 precisely transmits this second liquid to the capacitive deionization unit 2 through a second pipeline. Inside the capacitive deionization unit 2, through specific operations (such as reverse charging of the electrodes), the ions previously adsorbed on the electrodes are effectively desorbed and rapidly dissolved into the flowing second liquid, forming a high-ion-concentration waste liquid. To prevent these high-concentration waste liquids from re-entering the retention system or causing environmental pollution, this application includes a waste liquid storage unit 4. This waste liquid storage unit 4 is directly connected to the capacitor deionization unit 2 via a fourth pipeline. Once the capacitor deionization unit 2 completes ion desorption and dissolves the ions in the second liquid, the resulting waste liquid is guided through the fourth pipeline and discharged to the waste liquid storage unit 4 for centralized collection and management. This design ensures that the waste liquid generated during the desorption process can be promptly and effectively isolated from the main circulation system, thereby avoiding secondary pollution of the retention system's water quality and ensuring the stability and cleanliness of the entire retention process. In this way, the capacitor deionization unit 2 can be efficiently regenerated, while the water quality environment of the entire retention system is continuously optimized and maintained. Furthermore, this embodiment utilizes the second liquid in the second storage tank 12 as the desorption medium, and in conjunction with the fourth pipeline to discharge the waste liquid, forms a closed-loop and efficient waste liquid treatment process. This ensures the regeneration efficiency of the capacitor deionization unit 2 and maintains the overall water quality stability and cleanliness of the retention system, providing a healthier and more stable living environment for the products to be retained.

[0062] In one exemplary embodiment, reference Figure 1 As shown, an ion concentration regulation system, a preservation system, and a cold storage are provided. In this embodiment, the preservation unit 4 may include an aqueous preservation unit. An aqueous preservation unit refers to a device that preserves the product by immersing it in a liquid medium. This type of unit is typically suitable for products requiring an aquatic environment, such as various aquatic products. It can be implemented as a large aquaculture pond, a water tank with a water circulation and filtration system, or a temporary holding tank with water exchange capabilities.

[0063] In this embodiment, the water protection unit may include a circulating water tank 411, a product storage pool 412, and a circulation control component 413 connected in sequence. The product storage pool 412 contains a salt solution to keep the product to be kept alive. The circulation control component 413 is configured to control the circulation of the salt solution between the circulating water tank 411 and the product storage pool 412. The capacitor deionization unit is connected to the circulating water tank 411 and is used to provide the circulating water tank 411 with a salt solution within the target ion concentration range.

[0064] The circulating water tank 411 is a container used to store and regulate the brine solution, and its main function is to act as a buffer and processing node in the brine solution circulation path. It receives the brine solution from the product storage pool 412 and is connected to the capacitor deionization unit for ion concentration regulation. The circulating water tank 411 can be made of corrosion-resistant materials (such as food-grade plastic, stainless steel, or fiberglass), and its volume can be designed according to the scale and processing capacity of the survival system.

[0065] The product storage pool 412 is a container directly used to store products to be kept alive. It contains a salt solution to provide a direct environment for keeping the products alive. The design of this storage pool should take into account the type and quantity of the products to be kept alive, as well as their space requirements. The product storage pool 412 can be made of transparent material for observation, or of material with good thermal insulation properties. Its implementation can be, but is not limited to: using an open or semi-closed structure to facilitate product loading and unloading; or using a design with dividing grids to distinguish different batches or types of products.

[0066] The circulation control component 413 controls the circulation of the brine solution between the circulating water tank 411 and the product storage tank 412, ensuring the uniformity of the brine solution and the stability of the water quality. For example, the circulation control component 413 includes a temperature and oxygen control device, which enables liquid circulation between the circulating water tank 411 and the product storage tank 412. The temperature and oxygen control device controls the temperature and oxygen concentration of the brine solution in the water-holding unit to maintain them within target ranges. The temperature and oxygen control device is a device that integrates temperature and oxygen concentration regulation functions. It may include a temperature sensor, a heating / cooling device, a dissolved oxygen sensor, and an aeration / deoxygenation device. The temperature sensor monitors the temperature of the brine solution in real time, and the heating / cooling device heats or cools the brine solution according to the monitoring results to maintain it within a preset target temperature range. The dissolved oxygen sensor monitors the oxygen concentration in the brine solution in real time, and the aeration / deoxygenation device injects oxygen into the brine solution or removes excess oxygen according to the monitoring results to maintain it within a preset target oxygen concentration range. The temperature and oxygen control device integrates a water pump to drive the liquid flow.

[0067] The circulation control component 413 is connected to the capacitor deionization unit 2 via a sixth pipeline. A control valve is installed on the sixth pipeline to control its opening or closing. When the ion concentration of the salt solution in the aqueous retention unit deviates from the target ion concentration range, the circulation control component 413 controls the transfer of the salt solution from the aqueous retention unit to the capacitor deionization unit. The capacitor deionization unit adjusts the salt solution back to the target ion concentration range and then returns it to the aqueous retention unit.

[0068] The circulating water tank 411 is connected to the product storage pool 412 via a seventh pipe, the product storage pool 412 is connected to the circulation control component 413 via an eighth pipe, and the circulation control component 413 is connected to the circulating water tank 411 via a ninth pipe. An ion concentration detection device, designated as the fourth ion concentration detection device 40, is installed on the eighth pipe. This device is used to detect the ion concentration of the salt solution discharged from the product storage pool 412. This ion concentration can be used as the ion concentration of the salt solution in the water-based preservation unit.

[0069] In the aqueous preservation unit, the brine solution continuously circulates between the circulating water tank 411 and the product storage pool 412, providing a stable environment for the product to be preserved. To ensure this stability, a fourth ion concentration detection device 40 continuously monitors the ion concentration of the brine solution within the aqueous preservation unit. Once the ion concentration of the brine solution deviates from the preset target ion concentration range, the preservation system controls the control valve on the sixth pipeline to open, and the circulation control component 413 transfers the brine solution from the product storage pool 412 to the capacitor deionization unit through the sixth pipeline. The control valve on the sixth pipeline ensures that the sixth pipeline is open when transfer is needed and closed when transfer is not needed, thereby achieving on-demand and efficient delivery of the brine solution and avoiding unnecessary energy consumption and water quality fluctuations. After receiving the brine solution that deviates from the target range, the capacitor deionization unit can perform ion adsorption or desorption operations according to the actual situation to precisely adjust the ion concentration of the brine solution to the target ion concentration range required for the product to be preserved. After adjustment, the capacitor deionization unit returns the treated salt solution to the circulating water tank 411 of the water-containing preservation unit via a corresponding return pipeline (e.g., the fifth pipeline), reintegrating it into the circulation system of the water-containing preservation unit. This series of operations forms an automated closed-loop adjustment mechanism. Through direct communication and precise control between the circulation control component 413 and the capacitor deionization unit, the system can detect, respond quickly, and efficiently handle deviations in the salt solution ion concentration in real time. This mechanism avoids problems such as response lag, low treatment efficiency, or secondary water pollution that may exist in traditional methods, ensuring that the salt solution ion concentration in the water-containing preservation unit is always maintained within the optimal range required for the product to be preserved. Therefore, this solution significantly improves the water quality stability, reliability, and automation level of the preservation system, providing a more suitable living environment for the product to be preserved.

[0070] In this embodiment, a control valve can also be installed on the ninth pipeline to control the opening or closing of the ninth pipeline, thereby controlling the connection between the circulation control component 413 and the circulating water tank 411. When the capacitor deionization unit 2 needs to adjust the ion concentration of the salt solution in the water-containing retention unit, the control valve of the aforementioned ninth pipeline can be closed to prevent the salt solution discharged from the product storage tank 412 from entering the circulating water tank 411 and affecting the adjustment efficiency of the ion concentration of the salt solution.

[0071] One-way valves can also be installed on the seventh and eighth pipelines to ensure that the circulation direction of the salt solution in the water-based maintenance unit is: circulating water tank 411 - product storage pool 412 - circulation control component 413. Furthermore, combined with the control valve on the sixth pipeline, the ion concentration of the salt solution in the product storage pool 412 can be directly adjusted using the capacitor deionization unit 2, and then the salt solution meeting the target ion concentration range can be transferred to the circulating water tank 411 for subsequent circulation in the water-based maintenance system.

[0072] In some implementations... refer to Figure 1 As shown, this life-preservation system can be applied to cold storage facilities with water content. The system includes a first storage chamber 11, a second storage chamber 12, a first ion concentration detection device 10, a second ion concentration detection device 20, a solution mixing device 13, a capacitive deionization unit 2, a third ion concentration detection device 30, a wastewater storage unit 3, a circulating water tank 411, a product storage pool 412, and a circulation control component 413. The wastewater storage unit 3 can be, for example, a wastewater pool. The circulation control component 413 can be, for example, a temperature and oxygen control device with a water pump. All the aforementioned ion concentration detection devices can be ion concentration sensors.

[0073] In this embodiment, the first storage tank 11 is a storage tank for high-salinity liquid, and the salt concentration (i.e., ion concentration) of the first liquid stored therein can be in the range of 1%-2%. The second storage tank 12 is a storage tank for freshwater liquid, and the salt concentration of the second liquid stored therein is less than 0.05%. The first ion concentration detection device 10 can detect the ion concentration of the liquid extracted from the first storage tank 11. The second ion concentration detection device 20 can detect the ion concentration of the liquid extracted from the second storage tank 12. The solution mixing device 13 can be an intelligent mixing valve, which allows the user to set or automatically detect the target aquatic product and determine the target salt concentration range required by the aquatic product. Then, according to the required target salt concentration range, it automatically retrieves the liquid from the first storage tank 11 and the second storage tank 12 and mixes them to obtain a mixed liquid, which is the initial mixed liquid. The aforementioned initial mixed liquid is then deionized or has ions added by the capacitive deionization unit 2, so that the salt concentration of the liquid remains stable at the optimal salt concentration for the aquatic product, avoiding stress to the aquatic product. That is, the capacitive deionization unit 2 is used to adjust the ion concentration of the initial mixed liquid to the target ion concentration range. The third ion concentration detection device 30 can detect the ion concentration of the liquid after adjustment by the capacitor deionization unit 2.

[0074] In this embodiment, the salt solution with the desired target ion concentration range obtained above is input into the circulating water tank 411. The circulating water tank 411 is connected to the product storage tank 412 for aquatic products, and circulation is achieved through a temperature and oxygen control device. The temperature and oxygen control device can control the oxygen and temperature in the liquid within a suitable range for the aquatic products.

[0075] In addition, this embodiment also includes a fourth ion concentration detection device 40, which can be an ion concentration sensor. After a period of storage, the salt concentration inside the circulating liquid changes due to the metabolic behavior of aquatic products, which may affect the survival of the aquatic products. The fourth ion concentration detection device 40 is used to detect the ion concentration of the liquid discharged from the product storage tank 412. When the ion concentration deviates from the range required by the aquatic products, the protection system can control the connection between the temperature and oxygen control device and the capacitor deionization unit 2. The liquid will return to the capacitor deionization unit 2 through the passage between the temperature and oxygen control device and the capacitor deionization unit 2. The capacitor deionization unit 2 adjusts the salt concentration of the liquid, and then the third ion concentration detection device 30 detects whether the ion concentration of the liquid meets the requirements. If it meets the requirements (i.e., the ion concentration is within the target ion concentration range), it is introduced into the circulating water tank 411 to continue participating in the circulation within the circulating water tank 411-product storage tank 412-temperature and oxygen control device. The capacitor deionization unit 2 and the third ion concentration detection device 30 can be shut down to reduce energy consumption.

[0076] During the above process, the capacitive deionization unit 2 may adsorb ions that affect the pH of the liquid, such as ammonium ions. These ions cannot be released into the liquid in which aquatic products survive, so they need to be eluted. At this time, liquid can be discharged from the second storage tank 12 into the capacitive deionization unit 2, where the ions adsorbed in the capacitive deionization unit 2 are desorbed, and the resulting waste liquid is discharged into the waste liquid storage unit 4.

[0077] This implementation achieves breakthroughs in energy efficiency, water quality stability, intelligence, and multifunctional adaptability through the synergistic effect of a capacitive deionization module and a closed-loop control system. Capacitive deionization technology, based on the principle of electroadsorption, enables controllable removal and release of salt under low voltage. Combined with real-time salinity feedback to dynamically adjust operating parameters, it effectively reduces energy consumption. The ion concentration detection device detects the ion concentration of liquid at various locations, enabling rapid response and precise adjustment of salinity, avoiding stress on aquatic products caused by sudden salinity changes. Furthermore, the survival system can be equipped with the ability to automatically identify aquatic product types, set target ion concentration ranges, and adjust operating modes. It can also be equipped with remote monitoring and cloud management to achieve intelligent operation and maintenance across the entire chain. The capacitive deionization unit achieves "desalination" and "salting" functions through electrode reversal. Combined with an adjustable solution mixing device 13, it can achieve precise adjustment under different salinity requirements, making it suitable for various marine aquatic products and novel survival application scenarios.

[0078] In this embodiment, the survival system enables dynamic, precise, and automated regulation of the ion concentration of the brine solution in the aquatic survival unit. When the ion concentration of the brine solution deviates from the target range due to evaporation, product metabolism, or other factors, the system can promptly detect and activate the regulation mechanism, transferring the brine solution to the capacitor deionization unit for efficient processing and quickly returning it to the aquatic survival unit. This closed-loop automatic regulation effectively solves the problems of large water quality fluctuations, frequent manual intervention, and low regulation efficiency in traditional survival systems. Specifically, the direct connection between the circulation controller and the capacitor deionization unit, along with the precise management of the control valve, ensures that the brine solution can be transferred quickly and accurately between the two, avoiding delays and resource waste caused by path redundancy or improper control. The efficient ion regulation capability of the capacitor deionization unit, combined with the intelligent judgment and control of the circulation controller, allows the water quality in the aquatic survival unit to be maintained within the optimal ion concentration range required for the product to be survived for an extended period, significantly reducing the physiological stress and mortality risk of aquatic products caused by osmotic pressure imbalance. Therefore, this solution significantly improves the operational stability, reliability, and intelligence of the preservation system, providing a solid technical guarantee for the long-term preservation of various aquatic products, thereby increasing the survival rate and reducing operating costs. Furthermore, the introduction of temperature and oxygen control devices allows the temperature and oxygen concentration of the brine solution to be precisely maintained within the target range required for the products to be preserved, significantly reducing the physiological stress response caused by unstable environmental parameters. This not only helps maintain the health of aquatic products and reduce disease incidence but also greatly improves their survival rate and quality during preservation, providing a more stable and efficient guarantee for the transportation and temporary holding of aquatic products.

[0079] In one exemplary embodiment, reference Figure 2 As shown, an ion concentration regulation system, a product preservation system, and a cold storage are provided. In this embodiment, the product preservation unit 4 may include an anhydrous product preservation unit. An anhydrous product preservation unit refers to a device that does not completely immerse the product to be preserved in a liquid medium, but provides a preservation environment through other means. Such a unit is generally suitable for products that are sensitive to water immersion or require a specific humidity environment. It can be implemented as a sealed box that provides a humid environment through spraying or atomization, or as a dry or semi-dry storage space that maintains product activity through gas exchange and humidity control.

[0080] The anhydrous preservation unit includes a spray assembly 421 and a product storage chamber 422. The product storage chamber 422 is used to store the product to be preserved. The capacitor deionization unit is connected to the spray assembly 421 and is used to provide the spray assembly 421 with a salt solution of the target ion concentration range. The spray assembly 421 is used to spray the salt solution of the target ion concentration range into the product storage chamber 422.

[0081] It should be noted that the spray assembly 421 is a device used to atomize and uniformly spray the salt solution onto the surface of the product to be kept alive. Its function is to convert the liquid salt solution into fine droplets to achieve precise and uniform coverage of the product surface salinity. This assembly can consist of one or more nozzles, which can be pressure nozzles, ultrasonic atomizers, or pneumatic atomizers, with the spray flow rate, range, and frequency controlled mechanically or electronically. The product storage compartment 422 is the space or container in the anhydrous preservation unit used to actually store the product to be kept alive. It is designed to safely and stably contain the product and ensure it has sufficient contact with the salt solution sprayed by the spray assembly 421. The product storage compartment 422 can be a box with a tray or partitions, or a structure with a specific shape to accommodate different products; its material is typically chosen for its good corrosion resistance to salt solutions.

[0082] The connection between the capacitor deionization unit and the spray assembly 421 ensures that the salt solution with the target ion concentration range, precisely adjusted by the capacitor deionization unit, can be directly and effectively delivered to the spray assembly 421. The connection can be via flexible or rigid pipes and may include fluid control components such as pumps and valves to ensure stable salt solution delivery and flow control. The function of providing the spray assembly 421 with the salt solution of the target ion concentration range means that after adjusting the ion concentration of the initial salt solution, the capacitor deionization unit delivers the salt solution with the target ion concentration range required by the product to be kept alive to the spray assembly 421. This delivery can be continuous fluid delivery or intermittent supply on demand, achieved through a fluid pump or pressure system, ensuring that the spray assembly 421 always receives a salt solution with a precise concentration. The function of the spray assembly 421 in spraying the salt solution of the target ion concentration range into the product storage chamber 422 means that after receiving the salt solution from the capacitor deionization unit, the spray assembly 421 sprays it in an atomized form onto the product to be kept alive within the product storage chamber 422. The spraying method can be controlled by time, triggered by sensors, or dynamically adjusted according to product needs to ensure that the product surface obtains a suitable salinity environment and avoid over-spraying or under-spraying.

[0083] This embodiment effectively solves the technical problems of lacking a precise salt solution spraying mechanism, unstable salinity control, and difficulty in dynamically adapting to individual needs during anhydrous preservation. Specifically, the capacitive deionization unit can provide a salt solution with precisely controllable ion concentration, ensuring the quality of the salt solution from the source. The spray assembly 421 sprays this precise salt solution evenly in atomized form onto the surface of the product to be preserved in the product storage chamber 422, avoiding the lag in overall water salinity adjustment in traditional immersion preservation, and achieving rapid and precise replenishment of salinity on the product surface. This anhydrous spraying method not only significantly reduces water consumption and the burden of waste liquid treatment, but also avoids cross-contamination and water quality deterioration problems that may be caused by prolonged immersion of products in water. More importantly, this solution can achieve highly customized preservation management by adjusting the concentration, frequency, and duration of the sprayed salt solution according to the physiological characteristics and individual salinity requirements of different products to be preserved, thereby effectively preventing physiological stress and damage caused by osmotic pressure imbalance, and significantly improving the survival rate and quality of the products to be preserved.

[0084] In this embodiment, the spray assembly 421 may be disposed on the top of the product storage compartment 422. The spray assembly 421 includes multiple spray nozzles for spraying salt solution onto different areas of the product storage compartment 422, and the multiple spray nozzles are configured to allow individual operation.

[0085] It should be noted that the spray assembly 421 is located on top of the product storage compartment 422 to ensure that the salt solution can evenly cover the products to be preserved within the product storage compartment 422 from top to bottom. As one implementation, the spray assembly 421 can be fixedly installed inside the top cover of the product storage compartment 422 and connected to an external salt solution supply via piping. Alternatively, the spray assembly 421 can be integrated into a movable top cover of the product storage compartment 422 for easy maintenance and cleaning. The spray assembly 421 includes multiple spray nozzles designed to increase the coverage and flexibility of the spraying, enabling simultaneous or zoned spraying of different locations within the product storage compartment 422. For example, the spray nozzles can be fan-shaped nozzles, with the angle and number of nozzles adjusted to cover different areas; or, the spray nozzles can be atomizing nozzles to produce a fine mist of salt solution to improve coverage uniformity. These spray nozzles are used to spray salt solution onto different areas of the product storage compartment 422. This function aims to achieve precise spraying, avoid wasting sprayed areas, and ensure that areas requiring spraying are adequately covered. This can be achieved by using preset spray patterns to divide different spray areas according to the layout of the product storage compartment 422; or by combining sensors or visual recognition technology to dynamically identify product locations and perform targeted area spraying. Furthermore, multiple spray nozzles are configured to operate independently, meaning that each nozzle or group of nozzles can be independently opened, closed, or have its spray intensity adjusted, thus achieving precise area control. For example, each nozzle can be connected to an independent solenoid valve for independent control by a controller; or the nozzles can be grouped for control, with each group controlled by an independent valve or pump.

[0086] This embodiment solves the problem of uneven spraying by optimizing the specific configuration of the spray assembly 421, ensuring that the salt solution accurately covers different areas of the storage compartment. The spray assembly 421 is positioned at the top of the product storage compartment 422, allowing the salt solution to be sprayed evenly from top to bottom, covering the entire storage space and avoiding dead zones. The spray assembly 421 includes multiple spray nozzles, allowing simultaneous spraying of multiple areas, improving coverage efficiency and targeting. It is used to spray salt solution onto different areas of the product storage compartment 422, directly addressing regional differences and reducing resource waste. Furthermore, the multiple spray nozzles are configured to operate independently, providing independent control capabilities. Combined with the product position identified by the vision recognition device 423, it enables flexible adjustment of the spraying area, improving the accuracy of the preservation process. In the anhydrous preservation unit, the capacitive deionization unit 2 provides the spray assembly 421 with a salt solution adjusted to the target ion concentration range, and the spray assembly 421 then sprays the salt solution onto the product storage compartment 422. By mounting the spray assembly 421 on top of the product storage compartment 422 and configuring multiple independently operable spray nozzles, the preservation system can precisely control the spray range and intensity of the brine solution based on the distribution of products to be preserved within the product storage compartment 422. For example, when only a portion of the product storage compartment 422 contains products to be preserved, the system can activate only the spray nozzles in the corresponding areas, avoiding unnecessary spraying of empty areas, thereby saving brine solution and reducing energy consumption. When the product storage compartment 422 contains different types of products or products with different preservation requirements, the system can provide customized brine solution spraying through independently controlled spray nozzles according to the specific needs of products in each area, ensuring that each product receives a suitable preservation environment. This refined spray control mechanism enables the preservation system to perform preservation treatment on products more efficiently and accurately, significantly improving preservation effectiveness and resource utilization.

[0087] Additionally, a visual recognition device 423 may be provided within the product storage compartment 422 of this embodiment to identify the storage locations of different products to be kept alive within the product storage compartment 422. The capacitor deionization unit adjusts the ion concentration range of the salt solution transmitted to the spray assembly 421 based on the category of the product to be kept alive identified by the visual recognition device 423; the spray assembly 421 adjusts the spray nozzle for spraying the salt solution based on the storage location of the product to be kept alive identified by the visual recognition device 423.

[0088] The visual recognition device 423 is a device capable of acquiring image or video information and detecting, recognizing, and locating target objects through image processing and pattern recognition technologies. As one possible implementation, the visual recognition device 423 can be equipped with an intelligent camera containing an image sensor (e.g., a CCD or CMOS camera) and an image processing module, using a preset algorithm to identify features such as the shape, color, and texture of the product to be preserved. Alternatively, the visual recognition device 423 can integrate a deep learning model, using a trained neural network model to classify product images and detect targets, thereby identifying the product's category and precise location. The visual recognition device 423 provides crucial input information for subsequent adjustments to the salt solution concentration and selection of the spray nozzle, forming the foundation for precise preservation.

[0089] The capacitive deionization unit adjusts the ion concentration range of the saline solution transmitted to the spray assembly 421 based on the category of the product to be kept alive identified by the visual recognition device 423. Its function is to ensure that different categories of products to be kept alive (e.g., freshwater and marine products, or marine products with different salinity requirements) receive a saline solution concentration that matches their physiological needs. As one possible implementation, the capacitive deionization unit of this keeping-alive system can be internally or externally connected to a controller. This controller receives the product category information output by the visual recognition device 423, queries the target ion concentration range required for that product category according to a preset database or rule table, and then instructs the capacitive deionization unit to perform the corresponding ion concentration adjustment operation. Alternatively, the capacitive deionization unit can communicate with a central control system. The central control system dynamically calculates or selects a suitable ion concentration setpoint based on the product category provided by the visual recognition device 423 and sends it to the capacitive deionization unit, causing it to output a saline solution of the corresponding concentration.

[0090] The spray assembly 421, based on the storage location of the product to be kept alive identified by the vision recognition device 423, adjusts the spray nozzles for spraying salt solution. Its function is to achieve localized or directional spraying of the product to be kept alive at specific locations within the product storage compartment 422, avoiding repeated spraying of products that do not need spraying or have already been treated, thus improving efficiency and saving resources. As one possible implementation, the spray assembly 421 may include multiple independent spray nozzles, each controlled by an independent solenoid valve or micro-pump. When the vision recognition device 423 identifies a product to be kept alive in a certain area, the controller activates the corresponding spray nozzle based on the location information. Alternatively, the spray assembly 421 may employ a movable spray arm or an array of nozzles, driven by a stepper motor or servo motor to move the spray mechanism above the target location, or selectively activate specific nozzles in the array to achieve precise area spraying.

[0091] In some implementations... refer to Figure 2 As shown, the preservation system is applied in cold storage for waterless spray preservation of aquatic products. By combining capacitive deionization (CDI) technology with the spray system, it achieves precise control of the salt concentration of the spray droplets to maintain the physiological activity of aquatic products in a low-temperature, low-humidity environment. The preservation system may include a first storage chamber 11, a second storage chamber 12, a first ion concentration detection device 10, a second ion concentration detection device 20, a solution mixing device 13 (e.g., a smart mixing valve), a capacitive deionization unit 2, a third ion concentration detection device 30, a spray assembly 421, and a product storage chamber 422. The product storage chamber 422 can be a preservation warehouse, which may be equipped with shelves for storing products to be preserved. A visual recognition device 423 may also be installed in the preservation warehouse to identify the storage location of different products to be preserved within the product storage chamber 422. In this embodiment, each ion concentration detection device can be an ion concentration sensor.

[0092] In this embodiment, an ion concentration regulation system (i.e., a system consisting of a first storage tank 11, a second storage tank 12, a first ion concentration detection device 10, a second ion concentration detection device 20, a solution mixing device 13 (e.g., an intelligent mixing valve), a capacitor deionization unit 2, and a third ion concentration detection device 30) is added to the front end (i.e., upstream side) of the spray assembly 421 for online desalination or salting of the spray water. The salinity (ion concentration) required for the spray droplets is set according to the type of product to be kept alive and is preset in the control system. The third ion concentration detection device 30 can detect the salinity of the spray water in real time and feed the data back to the intelligent control terminal of the control system. The intelligent control terminal adjusts the voltage polarity and current intensity of the capacitor deionization unit 2 according to the feedback data to dynamically control the ion concentration of the spray droplets. The spray assembly 421 is located at the top of the keeping tank, which may store more than one type of aquatic product. Different aquatic products require different salt concentrations. The spray assembly 421 has multiple spray nozzles, each of which can operate independently. The spray assembly 421 can be configured to provide spray liquid with different salt concentrations (i.e., ion concentrations) according to different aquatic products on the shelf below. Additionally, in this embodiment, the visual recognition device 423 can identify the location of different aquatic products, feeding back location information and the required target concentration information to the intelligent control terminal. The terminal adjusts the voltage polarity and current intensity of the capacitor deionization unit based on the received information, dynamically controlling the salt concentration of the spray droplets. Simultaneously, it selects an appropriate spray nozzle position so that the aquatic products receive liquid within the correct salt concentration range (i.e., the target ion concentration range). The spray assembly 421 evenly sprays the adjusted salinity droplets onto the surface of the aquatic products, creating a humid microenvironment, preventing dehydration and salinity imbalance, and thus maintaining the survival of the products to be kept alive.

[0093] It should be noted that, Figure 2The liveness-preservation system shown in this embodiment does not include a wastewater storage unit. However, in other embodiments, the liveness-preservation system applied to waterless liveness-preservation scenarios may also include a wastewater storage unit, and there is no limitation on this.

[0094] This embodiment achieves intelligent identification of product storage location and category by setting a visual recognition device 423 within the product storage compartment 422, thereby dynamically adjusting the salt solution concentration and spraying position. Specifically, the visual recognition device 423 continuously monitors the product storage compartment 422, identifying the category and storage location of each product to be preserved. This identification information is transmitted to the control system. Based on the identified product category, the control system instructs the capacitor deionization unit to adjust the ion concentration range of its output salt solution to match the specific physiological needs of that product category. Simultaneously, based on the identified product storage location, the control system instructs the spray assembly 421 to adjust its spray nozzle, enabling it to accurately spray the salt solution onto the product to be preserved at the target location. This collaborative working method allows the entire preservation system to be customized according to the individual needs of different products, greatly improving the accuracy and efficiency of preservation. For example, when the spray assembly 421 of the anhydrous preservation unit has multiple spray nozzles that can operate independently, the precise location information provided by the visual recognition device 423 allows the spray assembly 421 to activate only the nozzles that need spraying, thereby achieving localized precise spraying and avoiding waste on areas that do not require treatment. In addition, the capacitive deionization unit can dynamically adjust the salt solution concentration according to the identified product category, enabling the entire survival system to not only provide the initial salt solution and adjust its ion concentration, but also to achieve on-demand customized supply of salt solution, thereby meeting the personalized salinity requirements of different types of aquatic products.
