Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable preservation technology, and in particular to a fruit and vegetable preservation system with a mobile storage compartment. Background Technology

[0002] With societal development, the demands for the quality of fruits and vegetables are increasing. However, the external environment in which fruits and vegetables move throughout the entire supply chain—from harvesting, sorting, storage, and transportation to retail—changes such as temperature and humidity, negatively impacting their quality. Research and analysis have revealed that while preservation treatments at the final stage are often effective, effective preservation measures are lacking in stages such as harvesting, sorting, storage, and transportation. Furthermore, existing preservation technologies and tools suffer from various design flaws, such as excessively long and complex processing chains. Therefore, more effective preservation treatments throughout the entire fruit and vegetable supply chain have become a new technological challenge with broad economic prospects and social value.

[0003] Regarding current fruit and vegetable preservation technologies and devices, existing patent solution one (application number: 201820378662.6; subject matter: a fruit and vegetable preservation box for easy transportation) discloses a fruit and vegetable preservation box. While this solution also addresses transportation, it primarily focuses on the placement and portability of fruits and vegetables, and is not suitable for large-scale harvesting and storage of fruits and vegetables. Existing patent solution two (application number: 202020490968.8; subject matter: a small mobile phase change cold storage preservation cold storage) discloses a mobile preservation cold storage. This solution mainly improves the energy configuration, and its application scenario is clearly unsuitable for timely preservation after harvesting, as well as for transfer and storage. Existing patent solution three (application number: 202121716058.8; subject matter: a combined fruit and vegetable preservation cold storage) discloses a combined preservation cold storage. This solution mainly improves the water mist function within the storage, but similarly, it is not clearly suitable for large-scale harvesting, transfer, and storage scenarios.

[0004] In summary, there is currently no existing technology that can be used for preservation and sterilization in the harvesting, storage, and transportation stages of the fruit and vegetable supply chain. Therefore, corresponding technical solutions and products urgently need to be developed and designed. Utility Model Content

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0036] refer to Figure 1-5 As shown, a fruit and vegetable preservation system with a mobile storage compartment includes a preservation compartment 100, a mobile vehicle 200, a preservation system 300, an ozone system 400, a monitoring system 500, and a control module 600. The preservation compartment 100 is a box-type structure used to hold fruits and vegetables requiring preservation, sterilization, and storage, and to perform these processes within it. The mobile vehicle 200 facilitates the movement of the preservation compartment 100. The preservation system 300, located inside and outside the preservation compartment 100, is a device for preserving fruits and vegetables, including necessary functional components and an electronic control module. The ozone system 400, located inside and outside the preservation compartment 100, is a device for ozone sterilization of fruits and vegetables, including necessary functional components and an electronic control module. The monitoring system 500, located inside and outside the preservation compartment 100, provides feedback on the preservation and sterilization effects of the fruits and vegetables, and includes necessary functional components and an electronic control module. The control module 600 is an integrated control assembly used to control the entire processing system, including corresponding electronic modules, electrical circuits and control programs.

[0037] like Figure 1 As shown, the refrigerated compartment 100 is mounted on the mobile vehicle 200 so that the refrigerated compartment 100 can move together with the mobile vehicle 200 when it needs to be moved. The refrigerated compartment 100 is equipped with a door 114.

[0038] In some preferred embodiments, to facilitate the fixed connection and disengagement between the refrigeration compartment 100 and the mobile vehicle 200, the bottom of the refrigeration compartment 100 is connected to the mobile vehicle 200 via a twist-lock mechanism, and structures adapted to accommodate the placement of the twist-lock mechanism are provided on the bottom of the refrigeration compartment 100 and the mobile vehicle 200. The twist-lock mechanism is a fixing tool. The twist-lock mechanism facilitates a secure connection between the refrigeration compartment 100 and the mobile vehicle 200, as well as their disassembly and separation, thereby enabling mutual replacement and transfer of the refrigeration compartment 100.

[0039] In practice, both the main body of the mobile vehicle 200 and the main structure of the refrigerated compartment 100 are made of metal.

[0040] In practical implementation, to adapt to the existing logistics and transportation system, the external dimensions of the refrigerated container 100 can be designed with reference to the size of a shipping container. Using a 20-inch standard container as a reference, the length would be approximately 6m, the width approximately 2.4m, and the height approximately 2.6m, resulting in a volume of approximately 23-28m. 3 The volume. Similarly, in practical implementation, it can also be constructed with reference to 40-inch standard containers, etc.

[0041] The preservation system 300 refers to the entire device that uses existing thermal energy technology to cool the air and then deliver it to the area around the fruits and vegetables to achieve cooling and preservation. It includes an evaporator 310 for directly generating cooling. The ozone system 400 refers to the entire device that uses existing technology to generate ozone, including an ozone supplier 410 for directly generating ozone. In specific implementations, the evaporator 310 and the ozone supplier 410 can be located inside or outside the preservation chamber 100. In specific implementations, after the evaporator 310 and the ozone supplier 410 generate low-temperature air and ozone respectively, they are delivered to the preservation chamber 100 through the piping system 700 and diffused around the fruits and vegetables, thereby achieving preservation and ozone sterilization. The piping system 700 refers to the entire pipeline used to guide and deliver low-temperature air and ozone, not a specific single pipe. In specific implementations, the connection method, valve settings, and arrangement of the piping system 700 are determined according to the actual environment.

[0042] The monitoring system 500 includes a temperature sensor 510 for monitoring the temperature inside the preservation compartment 100 and the temperature of fruits and vegetables, an ozone sensor 520 for monitoring the ozone concentration inside the preservation compartment 100, and a communication module and a data processing module attached to the sensor.

[0043] In some preferred embodiments, such as Figure 2 As shown, the refrigerated compartment 100 includes an upper shell plate 101, which refers to the outer shell plate located on the upper part of the refrigerated compartment 100. A top plate 102 is provided inside the refrigerated compartment 100, located below the upper shell plate 101. Figure 3As shown, the top plate 102 divides the space vertically into an accessory space 103 and a cargo space 104. In a specific implementation, the piping system 700 is located within the accessory space 103. Simultaneously, multiple top openings 105 are provided on the top plate 102 to allow the outlet end of the piping system 700 to connect to the cargo space 104 via the top openings 105. By separating the accessory space 103 and the cargo space 104 using the top plate 102, interference between the space used for housing the piping system 700 and the space used for storing fruits and vegetables is avoided.

[0044] In some preferred embodiments, such as Figure 4 As shown, the top panel 102 is divided into multiple top units, and each top unit is provided with a top opening 105. The piping system 700 is equipped with an independently controlled first valve to control the opening or closing of the piping system 700 within each top unit. The refrigerated compartment 100 includes a left side shell panel 106, a right side shell panel 107, and a lower shell panel 108. The left side shell panel 106 is provided with multiple roller shutter devices 109 for dividing the compartment space 104. Each roller shutter device 109 is positioned between two adjacent top units of the top panel 102, and the right side shell panel 107 is provided with a buckle corresponding to the roller shutter device 109 for securing it. Dividing the top panel 105 into multiple top units allows for the formation of independent spaces when used in conjunction with the roller shutter devices 109. Correspondingly, the piping system 700 is equipped with a first valve 701 and is independently controlled to control the operation or deactivation of the piping system 700 corresponding to each top unit. In practical use, if it is necessary to separately preserve and sterilize each area within the preservation compartment 100 and the area corresponding to the top unit, the curtain of the roller shutter device 109 is pulled out and fastened to the buckle to form an independent space, which has the beneficial effects of improving preservation and sterilization efficiency and reducing energy consumption.

[0045] In some preferred embodiments, the curtain of the roller blind device 109 includes tin foil for heat insulation. Tin foil has good heat insulation properties, reflecting the heat generated in the high-temperature area back and blocking heat convection. Furthermore, since it does not directly contact the fruits and vegetables, it utilizes its low thermal conductivity to provide insulation. In specific implementations, the curtain can be formed into a layered structure using various materials, with the remaining materials being cotton cloth and foam materials.

[0046] In some preferred embodiments, reference Figure 2-3As shown, the bottom of the compartment space 104 is provided with a bottom plate 110, and a bottom interlayer space 111 is formed between the bottom plate 110 and the lower shell plate 108. The upper surface of the bottom plate 110 is divided into multiple bottom units, and the positions of the bottom units correspond one-to-one with the top units. It also includes a storage frame 800 for holding fruits and vegetables. Each bottom unit is provided with a frame groove 112 for embedding the storage frame 800. The frame groove 112 is annular, and a negative pressure vent 113 is provided inside the annular shape. A negative pressure device 900 is provided in the bottom interlayer space 111 to generate negative pressure, which acts on the compartment space 104 through the negative pressure vent 113. The storage frame 800 is a tool for holding fruits and vegetables, and the size and shape of the fruit and vegetable frame 800 are adapted to the design of the compartment space 104 and the frame groove 112. In practical use, the lower edge of the fruit and vegetable crate 800 fits into the frame groove 112 to ensure stable placement. Multiple fruit and vegetable crates 800 can be stacked. A single fruit and vegetable crate 800 is the smallest unit for loading fruits and vegetables. In practical use, the negative pressure device 900 is activated, generating negative pressure airflow, causing the air in the compartment space 104 to flow out through the negative pressure air hole 113. Simultaneously, in conjunction with the top opening 105 located in the top unit, and the low-temperature preservation airflow and ozone flowing in from the top opening 105, the low-temperature preservation air and ozone can be rapidly and evenly flow through the space formed by the top unit, bottom unit, and roller shutter device 109, thereby improving the efficiency of the low-temperature preservation air and sterilizing ozone effect, and ensuring the balance of the low-temperature air and ozone atmosphere.

[0047] In some preferred embodiments, reference Figure 3 As shown, the negative pressure device 900 includes a negative pressure fan 901 and other auxiliary devices for supporting the operation of the negative pressure fan 901. In some specific embodiments, the negative pressure fan 901 is directly disposed in the bottom interlayer space 111; in other specific embodiments, the negative pressure fan 901 is disposed outside the preservation compartment 100, and provides negative pressure to the compartment space 104 through a negative pressure air pipe 902 connected to the negative pressure fan 901, which is connected to a negative pressure air hole 113, and the negative pressure air pipe 902 extends to the bottom interlayer space 111.

[0048] In some preferred embodiments, reference Figure 5As shown, the temperature sensor 510 includes one or both of the following: a temperature sensing tag and a short-wave infrared camera. In specific implementations, the temperature sensing tag can be directly attached to the surface of fruits and vegetables to improve the accuracy of temperature acquisition; the short-wave infrared camera senses the temperature of fruits and vegetables through infrared sensing. After acquiring the temperature data of fruits and vegetables, the temperature sensor 510 transmits the data to the technical backend. The algorithm program on the computing backend can calculate the temperature at the center of the fruits and vegetables, further improving the standards for fruit and vegetable temperature monitoring and preservation. The computing backend can be any computer capable of providing the corresponding computing power, and is configured according to requirements in specific implementations.

[0049] In some preferred embodiments, the evaporator 310 and the ozone supplier 410 are located outside the food storage compartment 100 and fixed to the food storage compartment 100 or the mobile vehicle 200. This preferred embodiment can save space inside the food storage compartment 100.

[0050] In some preferred embodiments, the control circuits of the preservation system 300 and the ozone system 400 are electrically connected to the control module 600 so that the preservation system 300 and the ozone system 400 can be coordinated and intelligently controlled by the control module 600.

[0051] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
