Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable transportation, in particular to a fruit and vegetable fresh-keeping device for long-distance transportation. Background Technique

[0002] Fresh fruits and vegetables are essential foods in daily life. At present, there are four main ways of fruit and vegetable transportation in China, such as road transportation, railway transportation, waterway transportation and air transportation. The most practical long-distance transportation is railway transportation, which has the advantages of fast speed, short time, stability and safety.

[0003] At present, the main means of fruit and vegetable transportation are low-temperature transportation, sealed transportation and sunshade transportation. However, due to the poor use effect of the existing fruit and vegetable fresh-keeping devices for long-distance transportation, no matter which transportation means is used, the final result is a high transportation damage rate of fruits and vegetables. Most of the existing devices cannot effectively prevent the evaporation of the moisture of the fruits and vegetables themselves, making the fruits and vegetables easily in a state of losing freshness, and the temperature control effect inside the transportation vehicle is poor, resulting in the easy growth of bacteria on the fruits and vegetables, thus affecting the edibility of the fruits and vegetables.

[0004] For example, a fruit and vegetable fresh-keeping device for long-distance transportation disclosed in the patent with the publication number of CN210695759U has a novel structural design, strong practicability, is convenient for continuously sterilizing and disinfecting fruits and vegetables, is convenient for spraying water to keep the fruits and vegetables moist, effectively improves its fresh-keeping effect, and effectively increases the function of buffer protection, and is suitable for use.

[0005] However, if too much water is sprayed on the fruits and vegetables during the use of this device, the water will accumulate at the bottom inside the placement plate, and the long-term contact between the water and the fruits and vegetables below will cause the fruits and vegetables to rot.

[0006] Therefore, we urgently need to provide a fruit and vegetable fresh-keeping device for long-distance transportation. Content of the Utility Model
