Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of cold storage for storage, and specifically, to a cold storage for fruit storage and a storage method. Background Art

[0002] A cold storage is a facility that maintains a certain low-temperature environment inside the warehouse through artificial refrigeration. It is mainly used for storing and preserving agricultural products such as various fruits, and other items that need to be stored at low temperatures. The cold storage of fruits mainly creates suitable external temperature and humidity environmental conditions, so that the fruits can minimize their own energy consumption and maintain normal and healthy life activities, thereby maintaining the fresh quality of the fruits.

[0003] When taking out the fruits stored in the cold storage, generally, the temperature in the cold storage is much lower than the outside temperature. When the fruits are stored in the cold storage, they are in a low-temperature environment, and their metabolic rate slows down. When the fruits are taken out of the cold storage and exposed to room temperature, the sharp change in temperature will cause damage to the internal cell structure of the fruits, thereby accelerating the ripening and rotting of the fruits. And when the fruits are taken out and exposed to the relatively dry air outside, the water evaporation speeds up, resulting in dehydration of the fruits and affecting their texture and taste.

[0004] Therefore, generally, when taking out the fruits stored in the cold storage, the refrigeration is generally stopped 2-3 days in advance, and the cold storage is allowed to naturally warm up to near the outside temperature before leaving the warehouse. However, if this operation is carried out, it can only be all taken out at one time, and the shutdown time needs to be planned in advance, which undoubtedly increases the operation complexity. And the natural warming process will cause uneven temperatures in different areas of the cold storage. Especially in the area near the air outlet, the temperature rises quickly, while the fruits in the corner or stacked densely may still be in a low-temperature state, causing local cold damage or accelerating deterioration, which instead affects the quality of the fruits. And this method is only applicable to one-time out-of-warehouse. If only a part of the fruits in the cold storage need to be taken out, it is difficult to adjust the fruit temperature before leaving the warehouse, resulting in difficulty in batch processing of fruits with different maturities or varieties, and it is difficult to supply high-value fruits according to demand grading. Summary of the Invention

[0005] To overcome the above defects, embodiments of the present disclosure provide a cold storage for fruit storage and a storage method, which solve the technical problems in the related art that when taking out the fruits stored in the cold storage, local cold damage is likely to occur during the warming process, and it is difficult to warm up some fruits in batches according to demand, resulting in difficulty in supplying high-value fruits according to demand grading.

[0006] The technical solution of the present disclosure is as follows: A cold storage for fruit storage, including a cold storage body. Inside the cold storage body, there are several independent cold storage boxes. A refrigeration device is installed inside the cold storage body. The intake end of the refrigeration device is connected to the outside through a pipeline, and the output end of the refrigeration device is connected to a ventilation pipeline. It further includes: A storage rack. Inside each cold storage box, there are several storage racks. Each storage rack is composed of several strip-shaped plates arranged at equal distances, and there is a gap between every two adjacent strip-shaped plates. Several storage racks are stacked vertically; A ventilation box. Inside each storage rack, a ventilation box is fixedly installed. The ventilation box is hollow. Each ventilation box is provided with a ventilation structure for sending cold air into the ventilation box to store and preserve the fruits placed on the storage rack; An air distribution component. An air distribution component is installed on the top of each cold storage box for performing an air supply operation on several ventilation boxes; An air supply temperature control component. The air supply temperature control component is installed on the cold storage body. The air supply temperature control component is respectively connected to several air distribution components for adjusting the storage temperature in one of several cold storage boxes.

[0007] On the basis of the foregoing solution, the ventilation structure includes: Trapezoidal grooves. Several trapezoidal grooves are equally spacedly opened on the upper part of several ventilation boxes. Several strip-shaped plates and several trapezoidal grooves are arranged alternately in the same direction; Through grooves. On the inclined surface of the side of each trapezoidal groove, several through grooves are equally spacedly opened along the direction of the trapezoidal groove; A connecting joint. The input end of each ventilation box is connected to a connecting joint.

[0008] On the basis of the foregoing solution, the air distribution component includes: An air distribution box. An air distribution box is fixedly installed on the top of each cold storage box. Several connecting pipes are connected to the bottom of each air distribution box. Several connecting pipes correspond to several connecting joints one by one; A detachable connection part. A detachable connection part is detachably arranged between several connecting pipes and several connecting joints for synchronously sending air into several ventilation boxes inside one cold storage box.

[0009] On the basis of the foregoing solution, the detachable connection part includes a hose. A hose is detachably connected between several connecting pipes and the corresponding several connecting joints through a union.

[0010] On the basis of the foregoing solution, the air supply temperature control component includes: Temperature detectors, each of which is installed inside the cold storage box body; Air inlet ducts, each of which is fixedly installed on the top of the cold storage box body. Both ends of the air inlet duct are set as input ends, and an air inlet branch is communicated between the side of the air inlet duct and the air distribution box body; Double-sided on-off part, which is installed inside the air inlet duct and used to control the on-off of the air entering both ends of the air inlet duct; Air supply part, which is installed on the air inlet duct and used to convey air.

[0011] On the basis of the foregoing solution, the double-sided on-off part includes: Connecting rods, each of which is coaxially arranged inside the air inlet duct; Conical plugging blocks, two of which are coaxially and fixedly installed at both ends of each connecting rod. The conical plugging blocks are respectively in sealing fit with the input ends at both ends of the air inlet duct; Driving parts, each of which is fixedly installed at one end of the air inlet duct, and the output end of the driving part is fixedly connected to one of the conical plugging blocks.

[0012] On the basis of the foregoing solution, the air supply part includes: Ventilation branches, several ventilation branches are communicated with the side of the ventilation pipeline, and several ventilation branches are respectively communicated with one of the input ends of several air inlet ducts; Air supply pipeline, which is fixedly installed on the top of the cold storage body. A plurality of air supply branches are communicated with the bottom of the air supply pipeline, and several air supply branches are respectively communicated with the other input ends of several air inlet ducts; Blower, which is fixedly installed on the top of the cold storage body, and the output end of the blower is communicated with the air supply pipeline.

[0013] On the basis of the foregoing solution, it further includes a placement box body. The placement box body is fixedly installed on the side of several cold storage box bodies. A sliding rack is slidably installed inside each placement box body, and one end of the sliding rack close to the entrance and exit of the cold storage box body is rotatably installed with a opening and closing door through a hinge support.

[0014] On the basis of the foregoing solution, when the sliding rack moves to the position of the placement box body close to the entrance and exit of the cold storage box body, at this time, the opening and closing door is pushed to rotate around the hinge support, so that the opening and closing door closes at the entrance and exit of the cold storage box body, and the cold storage box body forms a relatively sealed state.

[0015] A fruit storage method, which uses the above-mentioned cold storage for fruit storage, includes the following steps: Step 1: Placement. Open one of the cold storage boxes, and then place a storage rack at the bottom of the cold storage box. Step 2: Connection. Select a hose of appropriate length and connect the connecting pipe to the ventilation box in the corresponding storage rack. One end of the hose is connected to the connecting joint, and the other end is connected to the connecting pipe. Step 3: Stacking fruits. Pack the fruits well, then place the fruit boxes on the storage rack, and then place the next storage rack on this storage rack, ensuring that the storage racks are stacked stably. Then use another hose to connect the ventilation box in the corresponding storage rack to the corresponding connecting pipe, and then stack the fruit boxes on this storage rack again. Repeat the above steps until the cold storage box is full. Step 4: Closing. Pull the opening and closing door panel, and at the same time, the sliding rack moves in the placement box. When the sliding rack moves to the end of the placement box, the hinge support is just outside the placement box at this time. Then, with the hinge support as the center, rotate the opening and closing door panel to the cold storage box and fix the position of the opening and closing door panel to close the entrance and exit of the cold storage box. Step 5: Refrigeration. Start the refrigeration equipment. The cold air enters the air inlet cylinder through the settings of the ventilation pipeline and the ventilation branch. The conical plug block that controls the on-off between the air inlet cylinder and the ventilation branch is in the normally open state. When the low-temperature air enters the air inlet cylinder, it enters the air distribution box through the air inlet branch. At this time, the cold air passes through the connecting pipe and the hose in sequence until it enters the ventilation box through the connecting joint. The cold air entering the ventilation box is discharged into the cold storage box through multiple through slots on the trapezoidal groove. Step 6: Outbound. When fruits need to be taken out or some fruits need to be taken out, start the blower. The blower conveys air to the air supply pipeline, and through the settings of the air supply branch, the normal-temperature air is sent into the air inlet cylinder. When controlling the air flow rate entering the air inlet cylinder, the driving part drives the connecting rod to move, so that the conical plug block moves in the air inlet cylinder, thereby adjusting the size of the air inlet and controlling the inflow of low-temperature air and normal-temperature air. Through the real-time monitoring of the temperature detector, when the temperature in the cold storage box is the same as that outside, it can be taken out of the warehouse.

[0016] The beneficial effects of the embodiments of the present disclosure are as follows: 1. In the present disclosure, the cold air entering the ventilation box is discharged into the cold storage box through multiple through slots on the trapezoidal groove, evenly covering each fruit box. At the same time, it also avoids stacking multiple fruit boxes together, resulting in the cold air being unable to penetrate the middle layer, affecting the preservation effect, ensuring the same temperature, eliminating stacking dead corners, and improving the preservation consistency.

[0017] 2. In the present disclosure, the driving member drives the connecting rod to move, causing the conical plug block to move within the air inlet cylinder, thereby adjusting the size of the air inlet, controlling the inflow of low-temperature air and normal-temperature air, ensuring that the temperature inside the cold storage is controllable. It can not only accurately adjust the temperature of a single cold storage box, but also synchronously adjust the temperatures of multiple cold storage boxes, realizing batch-by-batch outbound, and avoiding the problem of local cold damage caused by a one-time overall shutdown and temperature rise.

[0018] 3. In the present disclosure, through the setting of the ventilation structure, since the storage racks can be customized according to needs and are stacked vertically, when storing fruits, there is a certain gap between each layer of fruit boxes. The ventilation structure cooperates with the air distribution component to uniformly cool down and warm up several stored fruit boxes. Through the setting of the air supply temperature control component, the storage environment is further controlled, thereby reducing the occurrence of local cold damage. The design of multiple cold storage boxes enables batch-by-batch outbound, allowing high-value fruits to be supplied according to demand grading. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be construed as indicating or implying relative importance.

[0028] Embodiment 1, as Figures 1 to 8 shown, which shows a cold storage for fruit storage in an embodiment of the present disclosure. A cold storage for fruit storage includes a cold storage body 1. Inside the cold storage body 1, there are several independent cold storage boxes 2. A refrigeration device 3 is installed inside the cold storage body 1. The intake end of the refrigeration device 3 is connected to the outside through a pipeline, and the output end of the refrigeration device 3 is connected to a ventilation pipeline 4. It also includes a storage rack 5, a ventilation box 6, an air distribution component, and an air supply temperature control component. Inside each cold storage box 2, there are several storage racks 5. The storage rack 5 is composed of several strip-shaped plates arranged at equal distances, and there is a gap between every two adjacent strip-shaped plates. Several storage racks 5 are stacked vertically. Inside each storage rack 5, a ventilation box 6 is fixedly installed. The ventilation box 6 is hollow. Each ventilation box 6 is provided with a ventilation structure for sending cold air into the ventilation box 6 to store and preserve the fruits placed on the storage rack 5. The ventilation structure includes a trapezoidal groove 7, a through groove 8, and a connecting joint 9. Several trapezoidal grooves 7 are equally spaced and opened at the upper part of several ventilation boxes 6. Several strip-shaped plates and several trapezoidal grooves 7 are arranged alternately in the same direction. On the inclined surface of the side of each trapezoidal groove 7, several through grooves 8 are equally spaced along the direction of the trapezoidal groove 7. The input end of each ventilation box 6 is connected to a connecting joint 9.

[0029] Specifically, when storing fruits, first pack the fruits well and place them in a turnover box or other boxes, hereinafter all referred to as fruit boxes. Then open one of the cold storage box bodies 2, and then place a storage rack 5 at the bottom of the cold storage box body 2. Connect the air distribution component to the ventilation box body 6 in this storage rack 5, and then the fruit boxes can be placed on the storage rack 5. Multiple fruit boxes can be neatly placed on the storage rack 5. After placing one layer of fruit boxes, if the height of the fruit boxes is relatively low, two layers can be placed. However, after stacking is completed, it is necessary to ensure that the upper fruit boxes do not contact the bottom of the upper storage rack 5 to ensure smooth circulation of cold air. After neatly placing the fruit boxes on this storage rack 5, place the next storage rack 5 on this storage rack 5. The dead corners at the top of the storage rack 5 are all provided with protrusions for positioning. These protrusions are adapted to the bottom of the storage rack 5 to play a role in positioning and fixing, ensuring the stable stacking of the storage racks 5. Then connect the air distribution component to the ventilation box body 6 in this storage rack 5, and then the fruit boxes can be stacked again on another storage rack 5. Repeat the above steps until the cold storage box body 2 is full. Finally, close the cold storage box body 2. At this time, start the refrigeration equipment 3. The cold air enters each ventilation box body 6 under the action of the air distribution component and the air supply temperature control component through the ventilation pipeline 4. The cold air entering the ventilation box body 6 is discharged into the cold storage box body 2 through multiple through slots 8 on the trapezoidal groove 7, evenly covering each fruit box. At the same time, it also avoids stacking multiple fruit boxes together, resulting in the cold air being unable to penetrate the middle layer, affecting the preservation effect, ensuring consistent temperature, and extending the preservation period. When it is necessary to take out fruits, especially when taking out some fruits, in order to avoid a large temperature difference between the inside of the cold storage box body 2 and the outside, resulting in frosting or moisture on the surface of the fruits, affecting the quality of the fruits. At this time, through the setting of the air supply temperature control component, the temperature in one or more cold storage box bodies 2 is adjusted to slowly rise to the outdoor temperature, thereby reducing the impact of the temperature difference on the fruits, improving the quality of the fruits, and also ensuring that the fruits will not be damaged due to excessive temperature difference during long-distance transportation, ensuring that the fruits maintain the best state during transportation, extending the time for maintaining the fresh taste, and at the same time not affecting the storage of other fruits.

[0030] As Figures 3 to 5 shown, an air distribution component is installed on the top of each cold storage box body 2 for performing an air supply operation on a plurality of ventilation box bodies 6. The air distribution component includes an air distribution box body 10 and a detachable connection part. An air distribution box body 10 is fixedly installed on the top of each cold storage box body 2. A plurality of connecting pipes 11 are communicated with the bottom of each air distribution box body 10. The plurality of connecting pipes 11 correspond to a plurality of communication joints 9 one by one. A detachable connection part is detachably arranged between the plurality of connecting pipes 11 and the plurality of communication joints 9 for synchronously sending air into the plurality of ventilation box bodies 6 inside one cold storage box body 2.

[0031] Specifically, after placing the fruit boxes containing fruits on the storage rack 5 on the first ventilation box body 6 and stacking the second storage rack 5 until the cold storage box body 2 is full, after placing the storage rack 5, it is necessary to set up a detachable connection part to dock the connecting pipes 11 of the air distribution component with the communicating joints 9 of the ventilation box body 6 one by one. When reducing the temperature inside the cold storage box body 2, low-temperature air is conveyed inside the air distribution box body 10 and is conveyed to the corresponding ventilation box body 6 through the connecting pipes 11 and the detachable communicating part to ensure that the cold air is evenly distributed to each fruit box and avoid local temperature differences.

[0032] As described above, such as Figure 4 、 Figure 5 shown, the detachable communicating part includes a hose 12. A hose 12 is detachably connected between each of the several connecting pipes 11 and the corresponding several communicating joints 9 through a union 13.

[0033] Specifically, the material of the hose 12 should be selected as a low-temperature resistant and anti-aging material. Both ends of the hose 12 are provided with unions 13. The union 13 is divided into a fixed end and a movable locking end. The former is directly installed on the connecting pipe 11 and the communicating joint 9, and the latter is installed at both ends of the hose 12. The fastening and disassembly are realized through the threaded engagement between the movable locking end and the fixed end.

[0034] It should be added that the movable locking end generally consists of two parts. One part is a connecting piece, which is directly connected to the hose 12, and the other part is a locking cap. The locking cap is rotationally matched with the connecting piece. The locking cap is fastened to the fixed end of the union 13 by rotation to ensure the firm connection of the hose 12, and it is not necessary to twist the hose 12. Moreover, the layout inside the warehouse can be flexibly adjusted to meet the storage requirements of different specifications of fruit boxes.

[0035] As Figures 6 to 8 shown, the air supply and temperature control component is installed on the cold storage body 1. The air supply and temperature control component is respectively communicated with several air distribution components for adjusting the storage temperature inside a certain cold storage box body 2 among several. The air supply and temperature control component includes a temperature detector 27, an air inlet cylinder 14, a bilateral on-off part, and an air supply part. The temperature detector 27 is installed inside each cold storage box body 2, and an air inlet cylinder 14 is fixedly installed on the top of each cold storage box body 2. Both ends of the air inlet cylinder 14 are set as input ends. An air inlet branch 15 is communicated between the side part of the air inlet cylinder 14 and the ventilation box body 6. The bilateral on-off part is installed inside the air inlet cylinder 14 for controlling the on-off of the air entering both ends of the air inlet cylinder 14. The air supply part is installed on the air inlet cylinder 14 for conveying air.

[0036] Specifically, when storing fruits in the cold storage box body 2 and it is necessary to lower the temperature, the temperature detector 27 is turned on for real-time monitoring at this time, and the air intake volume is adjusted through the double-sided on-off part. The air supply part is used to perform an air supply operation towards the air inlet cylinder 14. The air inlet cylinder 14 evenly sends low-temperature air into the air distribution box body 10 through the air inlet branch 15, ensuring that the low-temperature air sent to each ventilation box body 6 is uniform and stable, avoiding damage to the fruit quality caused by temperature differences. When it is necessary to take out the fruits stored in one or more cold storage box bodies 2, the double-sided on-off part at the top of the corresponding cold storage box body 2 can be adjusted separately to introduce external air, and preliminary mixing is carried out at the air inlet cylinder 14, and then it is sent into the air distribution box body 10 and finally enters the inside of the cold storage box body 2 through the ventilation box body 6. Through the real-time monitoring of the temperature detector 27, the temperature increase each time does not exceed 4°C of the temperature during fruit storage, generally set to 2-3°C. After the temperature is increased, this temperature will be maintained for a period of time to ensure that the fruits gradually adapt to the external environment, reduce the occurrence of frostbite or spoilage of the fruits caused by sudden temperature changes, and at the same time maintain an appropriate humidity to prevent water loss, and at the same time will not affect the storage state of the fruits in other cold storage box bodies 2.

[0037] As described above, Figure 6 As shown in the figure, the double-sided on-off part includes a connecting rod 16, a conical plug 17 and a driving member 18. A connecting rod 16 is coaxially arranged inside each air inlet cylinder 14. Two conical plugs 17 are coaxially and fixedly installed at both ends of each connecting rod 16. The conical plugs 17 are hermetically matched with the input ends at both ends of the air inlet cylinder 14 respectively. A driving member 18 is fixedly installed at one end of each air inlet cylinder 14. The output end of the driving member 18 is fixedly connected to one of the conical plugs 17. The driving member 18 can be in the form of an electric cylinder or the like.

[0038] Specifically, when controlling the air flow rate entering the air inlet cylinder 14, the driving member 18 drives the connecting rod 16 to move, so that the conical plug 17 moves in the air inlet cylinder 14, thereby adjusting the size of the air inlet, and thus controlling the inflow rate of the low-temperature air, ensuring that the temperature in the cold storage is controllable, thereby maintaining the best storage environment for the fruits. It can not only accurately adjust the temperature of a single cold storage box body 2, but also synchronously adjust the temperatures of multiple cold storage box bodies 2 to achieve overall temperature control.

[0039] As described above, Figure 1 、 Figure 2As shown in the figure, the air supply section includes a ventilation branch 19, an air supply pipeline 20, and a blower 22. A plurality of ventilation branches 19 are connected to the side of the ventilation pipeline 4. Each of the plurality of ventilation branches 19 is connected to one of the input ends of a plurality of air inlet cylinders 14. The air supply pipeline 20 is fixedly installed on the top of the cold storage body 1. A plurality of air supply branches 21 are connected to the bottom of the air supply pipeline 20. Each of the plurality of air supply branches 21 is connected to the other input end of a plurality of air inlet cylinders 14. The blower 22 is fixedly installed on the top of the cold storage body 1, and the output end of the blower 22 is connected to the air supply pipeline 20.

[0040] Specifically, when transporting low-temperature air, the refrigeration device 3 transports the low-temperature air to the ventilation branch 19 through the ventilation pipeline 4 and enters the air inlet cylinder 14. When it is necessary to adjust the temperature of the corresponding cold storage box 2, the driving member 18 is started, and the conical plug 17 is driven to move along with the connecting rod 16 to adjust the size of the air inlet. At the same time, the blower 22 is started, and the blower 22 transports air to the air supply pipeline 20. The air temperature is the same as the outside temperature. Through the arrangement of the air supply branches 21, the normal-temperature air is sent into the air inlet cylinder 14.

[0041] As described above, such as Figure 7 、 Figure 8 shown in the figure, it further includes a placement box body 23. The placement box body 23 is fixedly installed on the side of each of the plurality of cold storage box bodies 2. A sliding frame 24 is slidably installed inside each placement box body 23. One end of the sliding frame 24 close to the entrance and exit of the cold storage box body 2 is rotatably installed with an opening and closing door panel 26 through a hinge support 25. When the sliding frame 24 moves to the position of the placement box body 23 close to the entrance and exit of the cold storage box body 2, at this time, the opening and closing door panel 26 is pushed to rotate around the hinge support 25, so that the opening and closing door panel 26 closes the entrance and exit of the cold storage box body 2, making the cold storage box body 2 in a relatively sealed state.

[0042] Specifically, when it is necessary to close one or more of the cold storage box bodies 2, only the corresponding sliding frame 24 and the opening and closing door panel 26 need to be operated to achieve independent closing. At this time, the opening and closing door panel 26 is pulled, and at the same time, the sliding frame 24 moves in the placement box body 23 along with it. When the sliding frame 24 moves to the end of the placement box body 23, the hinge support 25 is just outside the placement box body 23 at this time. Then, with the hinge support 25 as the center, the opening and closing door panel 26 is rotated to the cold storage box body 2 and the position of the opening and closing door panel 26 is fixed, so as to close the entrance and exit of the cold storage box body 2 without affecting the use of other cold storage box bodies 2, ensuring that the storage states of the fruits in each box do not interfere with each other.

[0043] It should be added that not only can a single fruit be stored, but also different fruits can be stored. By independently adjusting the temperature of each cold storage box body 2, the storage requirements of different fruits can be met. However, it should be noted that only one kind of fruit can be stored in a single cold storage box body 2 to avoid the cross-influence of the smells and microorganisms between different fruits.

[0044] The working principle or usage process of this application is as follows: When storing fruits, first pack the fruits well, then open one of the cold storage box bodies 2, then place a storage rack 5 at the bottom of the cold storage box body 2, then select a hose 12 of appropriate length, and connect the connecting pipe 11 to the ventilation box body 6 in the corresponding storage rack 5. One end of the hose 12 is connected to the connecting joint 9, and the other end is connected to the connecting pipe 11. After connection, the fruit boxes can be placed on the storage rack 5. Multiple fruit boxes can be neatly placed on the storage rack 5. After placing one layer of fruit boxes, if the height of the fruit boxes is relatively low, two layers can be placed, but after stacking is completed, it is necessary to ensure that the upper fruit boxes do not contact the bottom of the upper storage rack 5 to ensure smooth circulation of cold air. After neatly placing the fruit boxes on this storage rack 5, place the next storage rack 5 on this storage rack 5 and ensure that the storage racks 5 are stably stacked. Then repeat the above steps, and use another hose 12 to connect the ventilation box body 6 in the corresponding storage rack 5 to the corresponding connecting pipe 11. Then stack the fruit boxes on this storage rack 5 again, and repeat the above steps until the cold storage box body 2 is full.

[0045] When refrigerating, it is necessary to first close the entrance and exit of the cold storage box body 2. At this time, pull the opening and closing door panel 26, and at the same time, the sliding rack 24 moves in the placement box body 23. When the sliding rack 24 moves to the end of the placement box body 23, the hinge support 25 is just outside the placement box body 23. Then, with the hinge support 25 as the center, rotate the opening and closing door panel 26 to the cold storage box body 2 and fix the position of the opening and closing door panel 26, so as to close the entrance and exit of the cold storage box body 2 without affecting the use of other cold storage box bodies 2, ensuring that the storage states of the fruits in each box are not interfered with each other. Start the temperature detector 27 to monitor in real time. At this time, start the refrigeration equipment 3. The cold air enters the air inlet cylinder 14 through the setting of the ventilation pipeline 4 and the ventilation branch 19. The conical blocking block 17 that controls the on-off between the air inlet cylinder 14 and the ventilation branch 19 is in the normally open state. When the low-temperature air enters the air inlet cylinder 14, it enters the air distribution box body 10 through the air inlet branch 15. At this time, the cold air passes through the connecting pipe 11 and the hose 12 in sequence until it enters the inside of the ventilation box body 6 through the connecting joint 9. The cold air entering the ventilation box body 6 is discharged into the cold storage box body 2 through the multiple through slots 8 on the trapezoidal groove 7, evenly covering each fruit box, and at the same time avoiding stacking multiple fruit boxes together, resulting in the cold air being unable to penetrate the middle layer and affecting the preservation effect.

[0046] When it is necessary to take out fruits, especially when taking out part of the fruits, in order to avoid a large temperature difference between the inside of the cold storage box body 2 and the outside world, which may cause frosting or moisture absorption on the surface of the fruits and affect the quality of the fruits, the blower 22 is started at this time. The blower 22 conveys air towards the air supply pipeline 20, and the air temperature is the same as the outside temperature. Through the setting of the air supply branch 21, the normal temperature air is sent into the air inlet cylinder 14. When controlling the air flow rate entering the air inlet cylinder 14, the driving member 18 drives the connecting rod 16 to move, so that the conical blocking block 17 moves in the air inlet cylinder 14, thereby adjusting the size of the air inlet and controlling the inflow of low-temperature air and normal temperature air, ensuring that the temperature in the cold storage is controllable. Through the real-time monitoring of the temperature detector 27, the temperature increase each time does not exceed 4°C of the temperature during fruit storage, generally set to 2-3°C. After the temperature rises, this temperature will be maintained for a period of time to ensure that the fruits gradually adapt to the external environment, reduce the phenomenon of frostbite or spoilage of the fruits caused by sudden temperature changes, prevent water loss, and at the same time do not affect the storage state of the fruits in other cold storage box bodies 2, extend the time for maintaining the fresh taste, and at the same time do not affect the storage of other fruits.

[0047] Embodiment 2: Based on a cold storage for fruit storage, this embodiment 2 also proposes a fruit storage method, including the following steps: The first step is placement. Open one of the cold storage box bodies 2, and then place a storage rack 5 at the bottom of the cold storage box body 2. The second step is connection. Select a hose 12 with an appropriate length and connect the connecting pipe 11 to the ventilation box body 6 in the corresponding storage rack 5. One end of the hose 12 is connected to the connection joint 9, and the other end is connected to the connecting pipe 11. The third step is stacking fruits. Pack the fruits well, then place the fruit boxes on the storage rack 5, then place the next storage rack 5 on this storage rack 5, and ensure that the storage racks 5 are stacked stably. Then use another hose 12 to connect the ventilation box body 6 in the corresponding storage rack 5 to the corresponding connecting pipe 11, and then stack the fruit boxes on this storage rack 5 again. Repeat the above steps until the cold storage box body 2 is full. The fourth step is closing. Pull the opening and closing door panel 26, and at the same time the sliding rack 24 moves in the placement box body 23. When the sliding rack 24 moves to the end of the placement box body 23, the hinge support 25 is just outside the placement box body 23 at this time. Then, with the hinge support 25 as the center, rotate the opening and closing door panel 26 to the cold storage box body 2 and fix the position of the opening and closing door panel 26, thereby closing the entrance and exit of the cold storage box body 2. Step 5: Refrigeration. Start the refrigeration device 3. Cold air enters the air inlet cylinder 14 through the ventilation pipeline 4 and the ventilation branch 19. The conical blocking block 17 that controls the on / off between the air inlet cylinder 14 and the ventilation branch 19 is in the normally open state. When the low-temperature air enters the air inlet cylinder 14, it enters the air distribution box 10 through the air inlet branch 15. At this time, the cold air sequentially passes through the connecting pipe 11 and the flexible pipe 12 until it enters the inside of the ventilation box 6 through the connecting joint 9. The cold air entering the ventilation box 6 is discharged into the cold storage box 2 through multiple through-holes 8 on the trapezoidal groove 7. Step 6: Outbound. When it is necessary to take out fruits or take out some fruits, in order to avoid a large temperature difference between the inside of the cold storage box 2 and the outside, which may cause frosting or moisture absorption on the surface of the fruits and affect the quality of the fruits. At this time, start the blower 22. The blower 22 conveys air to the air supply pipeline 20. The air temperature is the same as the outside temperature. Through the setting of the air supply branch 21, the normal-temperature air is sent into the air inlet cylinder 14. When controlling the air flow rate entering the air inlet cylinder 14, the driving member 18 drives the connecting rod 16 to move, so that the conical blocking block 17 moves in the air inlet cylinder 14, thereby adjusting the size of the air inlet and controlling the inflow of low-temperature air and normal-temperature air, ensuring that the temperature in the cold storage is controllable. Through the real-time monitoring of the temperature detector 27, the temperature increase each time does not exceed 4°C of the temperature during fruit storage, generally set to 2 - 3°C. After the temperature rises, this temperature will be maintained for a period of time to ensure that the fruits gradually adapt to the external environment, reduce the phenomenon of fruit frostbite or spoilage caused by sudden temperature changes, prevent water loss, and at the same time will not affect the storage state of fruits in other cold storage boxes 2, extend the time to maintain the fresh taste, and at the same time does not affect the storage of other fruits. When the temperature inside the cold storage box 2 is the same as the outside, it can be taken out of the warehouse.
