Description

Technical Field

[0001] The utility model relates to the technical field of fruit and vegetable fresh-keeping devices, and specifically to a logistics fresh-keeping device for vegetables and fruits. Background Art

[0002] Fruits and vegetables are one of the essential foods in people's daily diet, and kiwi, blueberry, prune and other fruits and vegetables can provide a variety of vitamins, minerals and other nutrients necessary for the human body.

[0003] However, fruits and vegetables such as kiwi, blueberry and prune are still living organisms after being harvested, and they will undergo complex life activities such as dormancy, water evaporation and respiration. These activities are closely related to the preservation of fruits, affecting and restricting the storage life of fruits. Among them, the external factors that affect the metabolic activities and storage effects of fruits are mainly temperature, gas composition and humidity.

[0004] In the prior art, the utility model with the authorization announcement number CN212686411U is named as a logistics preservation device for vegetables and fruits. The device proposed in the patent document adopts a small water pump, a sponge, a guide plate, and a small fan. When the small water pump is started, the ethylene action inhibitor solution is sucked out from the liquid storage tank through the water suction pipe and discharged to the sponge through the water delivery pipe. The sponge absorbs the ethylene action inhibitor. At this time, the fan is started to deliver the flowing air to the guide plate. The guide plates are arranged side by side for wind guidance, so that the wind blows directly on the sponge to accelerate the volatilization of the ethylene action inhibitor, thereby inhibiting the ripening effect of ethylene on vegetables and fruits, slowing down the ripening speed of vegetables and fruits, and thus playing a role in preservation. The power consumption of this device is small. After the transportation is completed in time, the device can also be placed in the warehouse to delay the ripening and decay time of vegetables and fruits.

[0005] However, the device proposed in the patent document can easily inhibit the ripening of fruits and vegetables, but it only inhibits the growth of fruits and vegetables. The temperature in the closed space can also affect the fruits and vegetables, aggravating the ripening effect of ethylene on fruits and vegetables, thereby poorly preserving the fruits and vegetables.
