Description

Technical Field

[0001] The invention belongs to the technical field of grain drying equipment, and in particular relates to a fully enclosed grain drying equipment based on internal circulation. Background Art

[0002] After harvesting grain, farmers usually dry it in the sun or oven to remove the surface moisture so that it can be stored. The processed grain is then stored in granaries, granaries or cellars.

[0003] However, although the surface moisture is effectively removed, the moisture inside the grain is difficult to evaporate quickly. Therefore, during long-term storage, the internal moisture will gradually precipitate, increasing the risk of grain mildew.

[0004] In order to reduce the mildew of grain, farmers will store the grain in a dry and ventilated environment, or turn the grain over and dry it regularly. However, finding or building a dry and ventilated environment will increase the difficulty and cost of storage, and turning the grain over and drying it regularly will increase the workload of farmers, which still has shortcomings. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a fully enclosed grain drying equipment based on internal circulation, so as to solve the technical problem that after the grain is dried, the moisture inside the grain is not easy to evaporate in a short period of time, and after a period of storage, the moisture inside the grain evaporates gradually, causing the grain to become moldy.

[0006] To achieve the aforementioned invention object, the technical solution adopted by the present invention includes: a fully enclosed grain drying device based on internal circulation, comprising a storage member, wherein the storage member has a receiving cavity for receiving grain; The storage component is provided with an air outlet connected to the accommodating cavity, and the storage component is provided with a dewatering component located in the accommodating cavity. The dewatering component includes a liquefaction component and a collecting component. The liquefaction component is at least used to liquefy water vapor in the accommodating cavity, and the collecting component is at least used to collect water liquefied by the liquefaction component.

[0007] In the present invention, the air in the accommodating chamber is extracted through the air outlet, so that a negative pressure environment can be formed in the accommodating chamber to facilitate the analysis of water inside the grain.

[0008] The collecting component includes a water storage bag and a collecting trough connected to the water storage bag, wherein the collecting trough is arranged inside the storage component, the collecting trough is located below the refrigeration fin, and the collecting trough is used to collect condensed water flowing down from the refrigeration fin. In the present invention, the liquefaction component includes a refrigeration plate, the refrigeration plate is fixedly arranged on the storage member, and the refrigeration surface of the refrigeration plate is located in the accommodating cavity, and the heating surface is located outside the storage member; In the present invention, the fully enclosed grain drying equipment based on internal circulation is mainly composed of three core components: a storage component, a liquefaction component and a collection component. It has a streamlined design and a small number of components, thereby achieving simplicity of structure and convenience of installation. In addition, due to the streamlining of components, the production and manufacturing costs are reduced, bringing significant economic benefits. When the grain is stored in a specially designed holding chamber, the liquefaction component and the collection component automatically work in the chamber. This automatic work means that for a considerable period of time, the operator does not need to perform additional operations, which greatly simplifies the operating process and improves work efficiency. At the same time, the automatic working mode of the equipment also makes it suitable for long-term and continuous work tasks, further improving its application value and practicality.

[0009] Preferably, the water storage bag is located outside the storage element.

[0010] In the present invention, by arranging the water storage bag outside the storage component, the water storage bag can be effectively prevented from being squeezed by the grain.

[0011] Furthermore, the water storage bag is made of hard material. Since the storage part will maintain a negative pressure state when storing food, the water storage bag is connected to the storage part, which will cause the internal pressure of the water storage bag to be less than the atmospheric pressure. If the material of the water storage bag is flexible, the air pressure difference will cause the water storage bag to compress and deform, and then the water in the water storage bag will be pressed back into the collection tank, affecting the water collection of the water storage bag.

[0012] In the present invention, the water storage bag is located in the accommodating cavity. By arranging the water storage bag in the accommodating cavity, the water storage bag is not easily affected by atmospheric pressure, and the material of the water storage bag is not restricted, which provides more options in production.

[0013] Preferably, the water removal component further comprises a mounting block, and the mounting block is fixedly mounted on the storage component; the refrigeration plate, the water storage bag and the collecting tank are all fixedly connected to the mounting block.

[0014] In the present invention, by using the mounting block as the mounting base for the refrigeration plate, the water storage bag and the collection tank, the above components can be pre-installed on the mounting block, and then the mounting block can be installed on the storage member, without having to install the above components on the storage member in turn, which is more convenient to operate.

[0015] Preferably, a heat dissipation component is installed on the mounting block, the heat dissipation component is located outside the storage component, and the heat dissipation component is at least used to assist the heating surface of the refrigeration fin in dissipating heat.

[0016] In the present invention, by using the heat dissipation component as the heat dissipation structure of the heating surface of the refrigeration plate, it is beneficial to accelerate the heat dissipation of the cooling surface of the refrigeration plate, thereby reducing the temperature difference between the hot end and the cold end, enhancing the refrigeration effect, and when the temperature of the hot end is reduced, the cold end can absorb heat more effectively and release it into the environment, thereby reaching a lower temperature. At the same time, it also helps to reduce the accumulation of heat on the heating surface, so that the refrigeration plate can work continuously and stably.

[0017] Preferably, the storage piece is made of flexible material.

[0018] In the present invention, by limiting the material of the storage piece to be flexible, the gas in the accommodating cavity can be discharged by pressing the storage piece to form a negative pressure environment in the accommodating cavity, which is more convenient to operate.

[0019] Preferably, a storage opening is provided on the storage member.

[0020] In the present invention, the storage opening is used as a storage and access passage for grains, so that operators can take and put grains according to real-time needs.

[0021] Furthermore, a sealing cover is provided on the surface of the storage member, and the sealing cover is used to seal the storage opening at least. The sealing cover is used as a sealing structure of the storage opening to seal and close the storage opening to maintain a negative pressure environment in the accommodating cavity.

[0022] Preferably, the storage element has a bag-like structure.

[0023] In the present invention, the storage piece is provided as a bag-shaped structure, so that the storage piece can be easily stored and organized.

[0024] Preferably, it further comprises a monitoring module and a control module, wherein the monitoring module and the control module are both fixedly arranged on the storage element; The monitoring module is at least used to monitor the water content of the air in the containing chamber and send instructions to the control module; The control module is at least used to control the start and stop of the refrigeration plate.

[0025] In the present invention, by integrating the monitoring module, the control module and the refrigeration plate, the entire system can automatically monitor and adjust the humidity environment inside the storage item, making it more intelligent. The intelligent management method not only improves the storage quality, but also reduces manual intervention and errors caused by manual intervention.

[0026] Furthermore, the monitoring module is at least used to monitor the air pressure difference between the accommodating chamber and the outside of the storage element. By monitoring the air pressure difference, it is easy to understand the pressure conditions inside and outside the accommodating chamber, so as to make adaptive operations to the air pressure changes.

[0027] Compared with the prior art, the advantages of the present invention include: The fully enclosed grain drying equipment based on internal circulation provided by the present invention has a simple design and a small number of parts, thereby achieving simplicity of structure and convenience of installation, and is also conducive to reducing production costs; The present invention provides a fully enclosed grain drying device based on internal circulation. When the grain is stored in a specially designed containing chamber, the liquefaction component and the collection component automatically work in the chamber. This automatic operation means that the operator does not need to perform additional operations for a considerable period of time, which greatly simplifies the operation process and improves work efficiency. At the same time, the automatic working mode of the device also makes it suitable for long-term and continuous work tasks, further improving its application value and practicality. The present invention provides a fully enclosed grain drying device based on internal circulation, wherein the accommodating cavity provides a safe and enclosed storage space for grains, effectively preventing mold and mice from directly affecting the grains, thereby ensuring the storage quality and safety of the grains; The present invention provides a fully enclosed grain drying device based on internal circulation, wherein the air outlet allows the air in the containing chamber to be discharged to form a negative pressure environment. This negative pressure environment not only helps to reduce the pollution of the outside air to the grain, but also promotes the precipitation of moisture inside the grain, because under the negative pressure environment, the moisture inside the grain is more likely to diffuse outward through the cell membrane or pores; The fully enclosed grain drying equipment based on internal circulation provided by the present invention has a dewatering component which effectively increases the storage time of grains. The water vapor in the accommodating chamber is converted into liquid water by the liquefying component and collected by the collecting component. This process directly reduces the water vapor content in the accommodating chamber, thereby reducing the risk of grain rewetting. At the same time, as the water is continuously removed, the dewatering component can also maintain a negative pressure environment to a certain extent, forming a virtuous cycle and continuously promoting the precipitation of water inside the grains. This mechanism enables the accommodating chamber to maintain a dry and stable environment for a long time, reduces the risk of mildew during the storage process, and allows the grains to be stored for a longer time. The fully enclosed grain drying equipment based on internal circulation provided by the present invention collects the water generated by the liquefaction component, which can effectively prevent the water from returning to the containing chamber again to increase the humidity, further improve the integrity and effectiveness of the water removal process, and effectively avoid the adverse effects of repeated circulation of water on the grain storage environment. At the same time, the collected water can also be processed in a centralized and unified manner, making it more environmentally friendly. The fully enclosed grain drying equipment based on internal circulation provided by the present invention, compared with the existing grain storage method, only needs to store the grain in the storage device, and there is no need to store the grain in a dry and ventilated environment. The storage difficulty is lower, the cost is lower, and there is no need to turn the grain over regularly, which can reduce the workload of workers. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] In view of the deficiencies in the prior art, the inventor of this case has proposed the technical solution of the present invention after long-term research and extensive practice. The following will further explain the technical solution, its implementation process and principle, etc. in conjunction with the drawings in the embodiments of this application and specific implementation cases.

In addition, when positional terms such as both sides, outside, up and down are used, it should be understood that they are only used to facilitate understanding and description, considering that the structure may be facing other positions.

Terms such as "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a conflicting connection, or an integrated connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] See also Figure 1-4 The present invention provides a technical solution: a fully enclosed grain drying device based on internal circulation, comprising a storage component 1, the storage component 1 having a receiving cavity 2 for receiving grain, the receiving cavity 2 provides a safe and enclosed storage space for the grain after sun drying or baking, and effectively prevents the direct influence of the external environment (mainly mold, mice, etc.) on the grain.

[0037] See also Figure 1 and Figure 2The storage part 1 is provided with an air outlet 3 connected to the accommodating chamber 2. The air outlet 3 serves as an outflow channel for gas. The air in the accommodating chamber 2 can be extracted through the air outlet 3, thereby forming a negative pressure environment in the accommodating chamber 2. The negative pressure environment is conducive to the precipitation of free water inside the grain. This is because the negative pressure environment promotes the outward diffusion of air inside the accommodating chamber and accelerates the air flow on the surface of the grain particles, making it easier for free water to be carried out of the grain particles and escape to the outside of the accommodating chamber. (It should be noted that the moisture in the grain mainly exists in two forms: one is free water, which is weakly bound to the grain particles and easily migrates when the external conditions change; the other is bound water, which is tightly bound to the grain particles and is not easy to be removed. Therefore, in the process of grain storage, the removal of free water is mainly done).

[0038] In addition, when the gas outlet 3 extracts the gas in the accommodating chamber 2, the gas outlet 3 can be connected to an external negative pressure device, such as a manual negative pressure pump, and the negative pressure device serves as a power source for gas extraction, which is convenient for extracting the gas in the accommodating chamber 2. It is worth noting that after we extract the gas in the accommodating chamber 2 through the gas outlet 3, we should seal the gas outlet 3 with a sealing plug to maintain the negative pressure state in the accommodating chamber 2. In addition, the setting position of the gas outlet 3 is not restricted, but in order to facilitate the operation of the staff, the gas outlet 3 should be set at a position that is convenient for the operator to operate according to the size of the storage unit 1.

[0039] See also Figure 3 and 4 The storage part 1 is provided with a dewatering component located in the accommodating chamber 2. The dewatering component includes a liquefaction component and a collection component. The liquefaction component is at least used to liquefy the water vapor in the accommodating chamber 2, and the collection component is at least used to collect the water liquefied by the liquefaction component. The liquefaction component converts the water vapor in the accommodating chamber 2 into liquid water, which is collected by the collection component. This process directly reduces the water vapor content in the air, thereby reducing the risk of grain rehumidification. At the same time, as the water is continuously removed, the dewatering component can also maintain a negative pressure environment to a certain extent, forming a virtuous cycle, and continuously promoting the precipitation of water inside the grain, which enables the fully enclosed grain drying equipment based on the internal circulation to continue to dry the grain for a long time. Subsequently, through the continuous operation of the dewatering component, not only the excess water in the accommodating chamber 2 can be removed, but also the negative pressure environment can be maintained to a certain extent. This mechanism enables the grain to be stored in a drier and more stable environment, reduces the risk of mildew during the storage process, and preserves it for a longer time.

[0040] In this embodiment, the liquefaction component includes a cooling fin 4 , which is fixedly disposed on the storage component 1 , and a cooling surface of the cooling fin 4 is located inside the accommodating cavity 2 , and a heating surface is located outside the storage component 1 .

[0041] When the refrigeration plate 4 is working, when the air with high humidity in the accommodating cavity 2 flows through the refrigeration surface, since the temperature of the refrigeration surface is lower than the dew point temperature of the air, the water vapor in the air will condense into water droplets on the refrigeration surface to form condensed water.

[0042] The collecting component includes a water storage bag 5 and a collecting groove 6 connected to the water storage bag 5, wherein the collecting groove 6 is arranged inside the storage component 1, and the collecting groove 6 is located below the refrigeration plate 4. The condensed water on the refrigeration surface of the refrigeration plate 4 can fall into the collecting groove 6 under the action of gravity and be collected by the collecting groove 6. It should be noted that in order to better collect the condensed water, the direction of the notch of the collecting groove 6 should be upward, and upward means that it can be tilted upward or vertically upward. The water storage bag 5 is arranged below the collecting groove 6, and the water in the collecting groove 6 can enter the water storage bag 5 and be stored under the action of gravity. By further storing the condensed water in the water storage bag 5, the possibility of the condensed water volatilizing again can be effectively reduced, thereby effectively preventing it from returning to the accommodating chamber 2 to increase the humidity again, and the water collected in the water storage bag 5 can also be uniformly treated, such as reuse or safe discharge, to make it more environmentally friendly.

[0043] Specifically, the water storage bag 5 and the collecting tank 6 are connected through the guide tube 7, one end of the guide tube 7 is connected to the water storage bag 5, and the other end is connected to the collecting tank 6. Furthermore, in order to be able to more thoroughly discharge the condensed water in the collecting tank 6 into the water storage bag 5, the collecting tank 6 is designed to be a cone shape with a larger upper part and a smaller lower part, and the connecting position between the guide tube 7 and the collecting tank 6 is at the bottom of the collecting tank 6.

[0044] In this embodiment, in order to effectively avoid the squeezing of the water storage bag 5 by the grain, the water storage bag 5 is arranged outside the storage part 1. By arranging the water storage bag 5 outside the storage part 1, the contact between the grain and the water storage bag 5 can be avoided, thereby effectively avoiding the squeezing of the grain by the water storage bag 5. Furthermore, in order to reduce the adverse effect of atmospheric pressure on the condensed water collection process in the water storage bag 5, the material of the water storage bag 5 is set to be hard. Considering that the storage part 1 will maintain a negative pressure state when storing grain, if the water storage bag 5 is connected to the inside of the storage part 1, its internal pressure will be lower than the external atmospheric pressure. The selection of hard materials significantly reduces the external squeezing effect of atmospheric pressure on the water storage bag 5, making it difficult for the condensed water in the water storage bag 5 to shrink back into the collection tank 6 due to the pressure difference, thereby effectively reducing the negative effect of atmospheric pressure on the collection of condensed water.

[0045] In other embodiments, in order to allow the water storage bag 5 to have more selectivity during production, the water storage bag 5 can also be arranged in the accommodating chamber 2. Since the water storage bag 5 is located in the accommodating chamber 2 and is not easily affected by the atmospheric pressure, the material of the water storage bag 5 will not be restricted and can be hard or soft, thereby having more selectivity during production.

[0046] In the present embodiment, in order to simplify the installation of various components and make it more convenient to install, the water removal component also includes a mounting block 8, and the mounting block 8 is fixedly mounted on the storage component 1; the refrigeration plate 4, the water storage bag 5, and the collecting tank 6 are all fixedly connected to the mounting block 8. By using the mounting block 8 as the installation basis for the refrigeration plate 4, the water storage bag 5 and the collecting tank 6, the above-mentioned components can be pre-installed on the mounting block 8, and then the mounting block 8 can be installed on the storage component 1. There is no need to install the above-mentioned components on the storage component 1 in sequence, and the operation is more convenient.

[0047] Specifically, the mounting block 8 is composed of a first plate, a second plate and a third plate. The second plate is located between the first plate and the third plate. The second plate is connected and fixed to the first plate by welding. The second plate is connected and fixed to the third plate by bolts. The cross-sections of the first plate, the second plate and the third plate form an H shape. The refrigeration fin 4 is arranged through the first plate and the second plate, and is connected and fixed to the first plate and the second plate by bonding. The third plate is provided with a first through hole for the heating surface of the refrigeration fin 4 to pass through. The collecting tank 6 is integrally arranged on the first plate. The water storage bag 5 is fixedly connected to the mounting block 8 by a fixing rope 9. The storage part 1 is provided with a second through hole for the second plate to pass through, and the outer edge of the second plate abuts against the inner wall of the second through hole.

[0048] During installation, first weld and fix the first plate and the second plate, then penetrate the refrigeration fin 4 on the first plate and the second plate, and glue and fix them, then pass the second plate through the second through hole from the inside of the storage unit 1 to the outside, and cover the third plate on the second plate. At this time, the heating surface of the refrigeration fin 4 should pass through the third plate and be located on the outside of the third plate, and then connect and fix the third plate to the second plate with bolts.

[0049] More specifically, according to the different materials of the water storage bag 5, the installation position of the water storage bag 5 is selected accordingly. When the water storage bag 5 is located on the outside of the storage component 1, the water storage bag 5 is fixed to the third plate body by a fixing rope 9. It should be noted that the guide tube 7 should also be made of a hard material in this case; when the water storage bag 5 is located on the inside of the storage component 1, the water storage bag 5 is fixed to the first plate body by a fixing rope 9.

[0050] Furthermore, when the water storage bag 5 is located outside the storage component 1, in order to facilitate the extraction of condensed water in the water storage bag 5, a water outlet pipe 10 is connected to the bottom of the condensed water, and a water outlet one-way valve 11 is arranged on the water outlet pipe 10. The water outlet one-way valve 11 only allows the condensed water in the water storage bag 5 to be discharged from the inside of the water storage bag 5 to the outside.

[0051] Furthermore, in order to increase the sealing performance between the second plate body and the storage member 1, a first sealing ring is embedded in the first plate body, and the first sealing ring surrounds the outer side of the second plate body. After the installation block 8 is installed, the first sealing ring abuts against the inner wall of the storage member 1. By providing the first sealing ring, the possibility of gas exchange between the storage member 1 and the outside through the gap between the second plate body and the second through hole can be effectively reduced, thereby increasing the sealing performance between the second plate body and the storage member 1.

[0052] Furthermore, in order to reduce the impact of the food inside the storage component 1 on the cooling surface of the refrigeration plate 4 and the collecting groove 6, an isolation cover 12 is fixedly arranged on the first plate body, and the isolation cover 12 is provided with a plurality of third through holes penetrating the isolation cover 12 along the thickness direction of the isolation cover 12. The collecting groove 6 and the cooling surface of the refrigeration plate 4 are both located inside the isolation cover 12. By using the isolation cover 12 as a protective structure for the cooling surface of the refrigeration plate 4 and the collecting groove 6, the food in the storage component 1 is not easy to contact the cooling surface of the refrigeration plate 4, so that the cooling surface of the refrigeration plate 4 is not easily worn by the food inside the storage component 1. At the same time, it is not easy for the food in the storage component 1 to fall into the collecting groove 6, thereby reducing the possibility of the food in the storage component 1 blocking the connecting channel between the collecting groove 6 and the water storage bag 5.

[0053] See also Figure 1 and 4 In this embodiment, in order to accelerate the heat dissipation of the heating surface of the refrigerating plate 4 located outside the storage unit 1, thereby enhancing the refrigeration effect and enabling the refrigerating plate 4 to work continuously and stably, a heat dissipation component 13 is installed on the mounting block 8. The heat dissipation component 13 is located outside the storage unit 1, and the heat dissipation component 13 is at least used to assist the heat dissipation of the heating surface of the refrigerating plate 4. By using the heat dissipation component 13 as the heat dissipation structure of the heating surface of the refrigerating plate 4, it is helpful to accelerate the heat dissipation of the refrigerating surface of the refrigerating plate 4, thereby reducing the temperature difference between the hot end and the cold end, enhancing the refrigeration effect, and when the temperature of the hot end is reduced, the cold end can absorb heat more effectively and release it to the environment, thereby reaching a lower temperature. At the same time, it also helps to reduce the accumulation of heat on the heating surface, so that the refrigerating plate 4 can work continuously and stably.

[0054] In this embodiment, in order to facilitate the discharge of air in the accommodating chamber 2, the storage component 1 is made of a flexible material. By limiting the material of the storage component 1 to be flexible, the gas in the accommodating chamber 2 can be discharged by pressing the storage component 1, which is more convenient to operate.

[0055] See also Figure 2 In this embodiment, in order to facilitate the taking and placing of grain, a storage opening 14 is provided on the storage member 1. By using the storage opening 14 as a storage and access channel for grain, grain can enter and exit the storage member 1 through the storage opening 14, thereby making it more convenient for operators to take and place grain.

[0056] Furthermore, in order to seal the storage port 14 so as to better maintain the negative pressure state in the storage component 1, a sealing cover 15 is provided on the surface of the storage component 1. The sealing cover 15 is at least used to seal the storage port 14. By using the sealing cover 15 as a sealing and closing structure of the storage port 14, the possibility of gas exchange between the accommodating chamber 2 and the outside through the storage port 14 is reduced, thereby forming a better negative pressure environment in the accommodating chamber 2.

[0057] Furthermore, the sealing cover 15 can be connected to the storage port 14 by means of threaded connection, snap connection, clamp connection or flange connection. The specific connection method is not limited. In the present embodiment, the inner wall of the sealing cover 15 is provided with an internal thread, and the outer wall of the storage port 14 is provided with an external thread. The sealing cover 15 and the storage port 14 are fixedly connected by a thread. The outer wall of the storage port 14 and the outer wall of the sealing cover 15 are respectively fixedly sleeved with a first ring body and a second ring body. The first ring body and the second ring body overlap in the vertical direction. A second sealing ring is embedded in the first ring body on one side relative to the second ring body. When the sealing cover 15 is closed on the storage port 14, the upper side of the second sealing ring is against the second ring body. By providing the second sealing ring, the possibility of gas exchange between the storage component 1 and the outside through the gap between the sealing cover 15 and the storage port 14 can be effectively reduced, thereby increasing the sealing between the sealing cover 15 and the storage port 14.

[0058] In this embodiment, in order to facilitate the storage and organization of the storage item 1, the storage item 1 is set to a bag-like structure. The storage item 1 with a bag-like structure can be better stacked, and when the storage item 1 is made of flexible material, the storage item 1 can also be folded, thereby saving space when storing the storage item 1.

[0059] In this embodiment, a monitoring module and a control module are also included, and both the monitoring module and the control module are fixedly arranged on the storage unit 1. The monitoring module is mainly responsible for real-time monitoring of the water content of the air in the accommodating chamber 2, which is usually achieved through a humidity sensor, which can sense and quantify the water vapor content in the air, thereby obtaining an accurate reading of the relative humidity. When the water content of the air is detected to be beyond a preset range, the monitoring module will send a corresponding instruction to the control module.

[0060] The monitoring module is at least used to monitor the water content of the air in the accommodating chamber 2 and send instructions to the control module. The control module controls the start and stop of the refrigeration plate 4 and other possible auxiliary equipment according to these instructions. The control module will decide whether to start or stop the refrigeration plate 4 according to the monitored humidity data and the preset humidity range. For example, if the humidity is too high and the temperature needs to be lowered to increase the condensation of water vapor, the control module will start the refrigeration plate 4; on the contrary, if the humidity is already very low, the control module will turn off the refrigeration plate 4 (mainly to save energy).

[0061] By integrating the monitoring module, the control module and the refrigeration plate 4, the entire system can automatically monitor and adjust the humidity environment inside the storage unit 1, making it more intelligent. The intelligent management method not only improves the storage quality, but also reduces manual intervention and errors caused by manual intervention.

[0062] In this embodiment, the monitoring module is at least used to monitor the air pressure difference between the accommodating chamber 2 and the outside of the storage unit 1, and send instructions to the control module. The monitoring module monitors the air pressure difference between the accommodating chamber 2 and the outside of the storage unit 1 in real time through an air pressure sensor. The air pressure sensor can sense and quantify the air pressure difference between the two areas, and provide accurate air pressure data for the control module. When it is detected that the air pressure difference exceeds the preset range, the monitoring module will send corresponding instructions to the control module. These instructions include adjusting the operating status of the refrigeration plate 4 or other adjustment measures. By monitoring the air pressure difference, it is easy to understand the pressure conditions inside and outside the accommodating chamber 2, so as to make adaptive operations to the air pressure changes, so that a better air pressure state can be maintained in the storage unit 1.

[0063] The main implementation steps of the present invention are as follows: Step 1: Complete the installation of each component; Step 2: Open the sealing cover 15, put the grain into the accommodating chamber 2 through the storage opening 14, and cover the sealing cover 15 (the sealing cover 15 can be opened later to take out the grain according to actual needs, and step 3 should be repeated after taking out the grain); Step 3: connect the air outlet 3 to a negative pressure device, and start the negative pressure device to extract the air in the accommodating chamber 2; Step 4: Use a sealing plug to block the air outlet 3 to maintain the negative pressure state in the accommodating chamber 2; Step 5: The dewatering component automatically works, and the water vapor in the air condenses into water droplets on the refrigeration surface to form condensed water. The condensed water can fall into the collecting tank 6 under the action of gravity and be collected by the collecting tank 6. The water in the collecting tank 6 is further stored in the water storage bag 5 under the action of gravity. Through the continuous operation of the dewatering component, not only the excess water in the accommodating chamber 2 can be removed, but also the negative pressure environment can be maintained to a certain extent. This mechanism enables the food to be stored in a drier and more stable environment, reduces the risk of mildew during the storage process, and the storage time is longer. Step 6: When the monitoring module detects that the moisture content of the air exceeds the preset range, the control module will decide whether to start or shut down the refrigeration sheet 4 according to the monitored humidity data and the preset humidity range. When the humidity is too high and the temperature needs to be lowered to increase the condensation of water vapor, the control module will start the refrigeration sheet 4; on the contrary, when the humidity is very low, the control module will shut down the refrigeration sheet 4; Step seven: When a large amount of condensed water is collected in the water storage bag 5, the condensed water in the water storage bag 5 is extracted through the water outlet pipe 10 (when the water storage bag 5 is located inside the storage component 1, the water storage bag 5 needs to be replaced by opening the sealing cover 15, and step three should be repeated after replacing the water storage bag 5).
