Description

Technical Field

[0001] This utility model relates to the field of cold chain storage and transportation of agricultural products, and in particular to a microenvironment modified atmosphere preservation container for fresh chili peppers. Background Technology

[0002] Fresh chili peppers, as a climacteric fruit and vegetable, retain strong physiological metabolic activity after harvest. If transported long distances at room temperature, they are prone to moisture evaporation, tissue shrinkage, and spoilage, leading to a significant decline in quality and economic value. Therefore, designing specialized microenvironment controlled atmosphere containers for high-respiration-intensity agricultural products like fresh chili peppers is of great significance in fruit and vegetable preservation and transportation technologies.

[0003] Current research on the transportation of fresh chili peppers mainly focuses on low-temperature cold chain and conventional modified atmosphere packaging. For example, patent document CN111907562A discloses a method for preserving and transporting vegetables by filling the container with protective gas to achieve atmosphere regulation. However, its structure is relatively simple and cannot dynamically control the gas concentration during transportation, leading to excessive accumulation of carbon dioxide, which can easily cause browning or dehydration inside the chili peppers.

[0004] It is evident that the existing technology has the following shortcomings: First, temperature and humidity control and gas composition regulation are often separated, lacking an integrated system; second, gas concentration regulation is lagging and cannot adapt to the dynamic changes in breathing intensity during transportation; and third, there are no protective measures against condensation accumulation, which can easily lead to mold and quality decline.

[0005] The technical problem to be solved by this application is to provide a microenvironment modified atmosphere preservation container for fresh peppers that can integrate temperature control, dynamic gas regulation and humidity balance protection throughout the transportation process, thereby effectively delaying the quality deterioration of fresh peppers and reducing losses during long-distance storage and transportation. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a microenvironment modified atmosphere preservation container for fresh chili peppers.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a microenvironment modified atmosphere preservation container for fresh chili peppers, comprising a container body, a preservation refrigeration unit installed at the upper end of the container body, a refrigeration fan installed on the outer wall of the preservation refrigeration unit, a container door installed at the front end of the container body, a connecting pipe installed between the preservation refrigeration unit and the container body, a ventilation window installed on the outer wall of the back of the container body, a protective steel mesh installed inside the container body, a honeycomb silicone pad installed below the protective steel mesh, a hydraulic rod installed between the protective steel mesh and the honeycomb silicone pad, ventilation holes installed inside the honeycomb silicone pad, a protective net frame installed at the upper end of the honeycomb silicone pad, a carbon dioxide removal device installed at the top of the protective steel mesh, a nitrogen filling device installed on one side of the honeycomb silicone pad, a spray nozzle connected to one end of the nitrogen filling device, and a control valve installed on the outer wall of the spray nozzle.

[0008] As a further description of the above technical solution:

[0009] The container door is movably connected to the front end of the container body, and there are two container doors. The refrigeration unit is fixedly installed on the top of the container body, and the refrigeration fan is rotatably connected to the outer wall of the refrigeration unit.

[0010] As a further description of the above technical solution:

[0011] The ventilation window is fixedly connected to the outer wall of the container body, and the refrigeration unit is fixedly connected between the container body and the connecting pipe.

[0012] As a further description of the above technical solution:

[0013] The protective steel mesh is fixedly installed on the top of the hydraulic rod, and the hydraulic rod is fixedly connected between the protective steel mesh and the honeycomb silicone pad. The carbon dioxide removal device is fixedly installed on the top of the protective steel mesh, and there are several hydraulic rods.

[0014] As a further description of the above technical solution:

[0015] The honeycomb silicone pad is placed below the protective steel mesh, and the ventilation holes are opened inside the honeycomb silicone pad. There are several ventilation holes, and the protective mesh frame is fixedly connected to the upper surface of the honeycomb silicone pad.

[0016] As a further description of the above technical solution:

[0017] The nitrogen filling device is fixedly installed inside the container body, the spray nozzle is integrally connected to the outer wall of the nitrogen filling device, the spray nozzle is connected to the nitrogen filling device, and the control valve is rotatably connected to the outer wall of the spray nozzle.

[0018] This utility model has the following beneficial effects:

[0019] In this invention, by installing a refrigeration unit and a cooling fan on the top of the container body and connecting them with pipes to deliver cold air, a low-temperature environment can be maintained throughout the transportation process, effectively reducing the respiration rate of fresh chili peppers and slowing down the consumption of nutrients and moisture.

[0020] A carbon dioxide removal device is installed to promptly remove excess carbon dioxide produced by the respiration of fresh chili peppers, preventing physiological damage caused by gas accumulation. Simultaneously, a nitrogen filling device and spray nozzles dynamically regulate the oxygen concentration inside the chamber, maintaining a low-oxygen environment for the chili peppers and significantly inhibiting their aging and spoilage. The honeycomb-shaped silicone pad has internal ventilation holes that evenly distribute gas and have a certain degree of moisture absorption, effectively preventing excessive condensation buildup inside the chamber. The protective steel mesh and frame work together to ensure the stability of the chili pepper stack while preventing condensation contact, reducing the risk of mold growth due to moisture.

[0021] The hydraulic rod supports the protective steel mesh and silicone pad structure, which can adjust the height and airflow path according to the stacking state, making the gas distribution more uniform; the ventilation window allows for limited air exchange, keeping the inside of the box in a micro-circulation, further enhancing environmental stability.

[0022] This invention organically combines a refrigeration system, a gas regulation system, and a protective humidity control structure to form an integrated microenvironment controlled atmosphere container. This not only extends the shelf life of fresh chili peppers and reduces the loss rate during long-distance transportation, but also effectively improves the product's commercial value and market circulation quality.

[0030] Reference Figure 1-3 One embodiment provided by this utility model:

[0031] Example 1:

[0032] A microenvironment modified atmosphere preservation container for fresh chili peppers includes a container body 1, a preservation refrigeration unit 3 installed at the top of the container body 1, a refrigeration fan 4 installed on the outer wall of the preservation refrigeration unit 3, a container door 2 installed at the front of the container body 1, a connecting pipe 5 installed between the preservation refrigeration unit 3 and the container body 1, a ventilation window 6 installed on the outer wall of the back of the container body 1, a protective steel mesh 7 installed inside the container body 1, a honeycomb silicone pad 8 installed below the protective steel mesh 7, a hydraulic rod 11 installed between the protective steel mesh 7 and the honeycomb silicone pad 8, ventilation holes 9 installed inside the honeycomb silicone pad 8, a protective net frame 10 installed at the top of the honeycomb silicone pad 8, a carbon dioxide removal device 12 installed on the top of the protective steel mesh 7, a nitrogen filling device 13 installed on one side of the honeycomb silicone pad 8, a spray nozzle 14 connected to one end of the nitrogen filling device 13, and a control valve 15 installed on the outer wall of the spray nozzle 14.

[0033] Working principle and usage process: During use, the refrigeration unit 3 delivers cold air to the interior of the container body 1 through the refrigeration fan 4 and connecting pipe 5, so that the temperature inside the container is maintained in the appropriate low temperature range for fresh peppers, thereby reducing the respiration rate of peppers; the carbon dioxide removal device 12 can adsorb and remove the carbon dioxide produced by the respiration of fresh peppers in a timely manner, preventing the physiological damage to peppers caused by excessive carbon dioxide concentration; the nitrogen filling device 13 releases nitrogen into the container through the spray nozzle 14, reducing the oxygen concentration and inhibiting the intensity of aerobic respiration of peppers.

[0034] The honeycomb silicone pad 8 has ventilation holes 9 inside, which can absorb and control moisture while maintaining air circulation, preventing condensation buildup and mold growth. The protective steel mesh 7 and the protective mesh frame 10 form upper and lower protective layers, ensuring the stability of the chili peppers during stacking and preventing direct contact with condensation or refrigeration components. The ventilation window 6 ensures a small amount of gas exchange between the inside and outside of the box, thus maintaining a stable gas environment. The hydraulic rod 11 is located between the protective steel mesh 7 and the honeycomb silicone pad 8, which can adjust the position of the steel mesh under different stacking conditions to ensure uniform airflow circulation.

[0035] Through the synergistic effect of the above-mentioned multiple processes, a microenvironment of "low temperature, low oxygen, and suitable humidity" is formed inside the container, which significantly delays the aging and spoilage of fresh chili peppers.

[0036] Example 2:

[0037] The container door 2 is movably connected to the front end of the container body 1. There are two container doors 2. The refrigeration unit 3 is fixedly installed on the top of the container body 1. The refrigeration fan 4 is rotatably connected to the outer wall of the refrigeration unit 3.

[0038] Ventilation window 6 is fixedly connected to the outer wall of container body 1, and refrigeration unit 3 is fixedly connected between container body 1 and connecting pipe 5.

[0039] The improvement of the implementation scheme of this embodiment compared with the prior art is that by setting two movable container doors 2 at the front end of the container body 1, the loading and unloading efficiency and flexibility are improved. Compared with the single-door container in the prior art, the operation time can be significantly shortened and the cargo damage rate can be reduced during the loading and sorting of large quantities of chili peppers.

[0040] The refrigeration unit 3 is fixedly installed on the top of the container body 1, and the refrigeration fan 4 is rotatably connected to the outer wall of the refrigeration unit 3 to form a vertical airflow circulation path, which makes the cold air more evenly distributed inside the container and effectively avoids the problems of insufficient local cooling or excessive temperature difference that are common in the prior art.

[0041] The ventilation window 6 is fixed to the outer wall of the container body 1. Combined with the fixed connection structure of the refrigeration unit 3 and the connecting pipe 5, the container has a stable airflow channel, which not only improves the uniformity of gas exchange, but also maintains good airtightness when there is vibration during transportation and changes in ambient temperature. This overcomes the defect of uneven gas exchange in the existing technology that leads to a decline in the quality of fresh peppers.

[0042] Example 3:

[0043] The protective steel mesh 7 is fixedly installed on the top of the hydraulic rod 11. The hydraulic rod 11 is fixedly connected between the protective steel mesh 7 and the honeycomb silicone pad 8. The carbon dioxide removal device 12 is fixedly installed on the top of the protective steel mesh 7. There are several hydraulic rods 11.

[0044] A honeycomb silicone pad 8 is placed below the protective steel mesh 7, and ventilation holes 9 are opened inside the honeycomb silicone pad 8. There are several ventilation holes 9, and the protective mesh frame 10 is fixedly connected to the upper surface of the honeycomb silicone pad 8.

[0045] The improvement of the implementation scheme of this embodiment compared with the prior art is that: by setting a number of hydraulic rods 11 between the protective steel mesh 7 and the honeycomb silicone pad 8, and fixing the protective steel mesh 7 on the top of the hydraulic rods 11, the support height and buffer force can be automatically adjusted according to the stacking weight and vibration during transportation. Compared with the single fixed support structure in the prior art, the compressive strength and stability of the internal structure are significantly improved, and mechanical damage to fresh peppers caused by stacking or vibration is avoided.

[0046] The honeycomb silicone pad 8 has several ventilation holes 9 inside, which not only improves the diffusion path of gas inside the container, but also has good moisture absorption properties, effectively alleviating the problem of condensation accumulation during transportation. A protective mesh frame 10 is fixedly installed on the upper surface of the honeycomb silicone pad 8, forming a double-layer protection system. This system provides physical isolation while regulating gas and controlling humidity, preventing fresh chili peppers from directly contacting the lower components and reducing the risk of quality degradation caused by condensation or uneven loading.

[0047] Example 4:

[0048] The nitrogen filling device 13 is fixedly installed inside the container body 1. The spray nozzle 14 is integrally connected to the outer wall of the nitrogen filling device 13. The spray nozzle 14 is connected to the nitrogen filling device 13. The control valve 15 is rotatably connected to the outer wall of the spray nozzle 14.

[0049] The improvement of the implementation scheme of this embodiment compared with the prior art is that by fixing the nitrogen filling device 13 inside the container body 1 and connecting the spray port 14 to it in an integrated manner, the connectivity and stability of nitrogen during the release process are guaranteed, avoiding the gas leakage problem caused by excessively long external pipes or loose interfaces in the prior art, making the nitrogen injection process more efficient and precise.

[0050] The spray nozzle 14 is located on the outer wall of the nitrogen filling device 13 and works in conjunction with the control valve 15 on the outer wall to adjust the amount of nitrogen released in real time according to the respiration intensity of the peppers in the box and changes in the environment.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
