A fully automatic adjustable fresh-keeping device for fruit and vegetable transportation

Abstract

The invention provides a full-automatic adjustable fresh-keeping device for fruit and vegetable transportation. The full-automatic adjustable fresh-keeping device for fruit and vegetable transportation comprises an outer box, an outer box door hinged to the outer box, an inner cover body arranged in the outer box, an inner box door hinged to the inner cover body, a storage rack arranged in the inner cover body, a driving device and a water tank. The storage rack comprises a support and a plurality of annular storage plates. The support is connected with the bottom of the outer box, and the annular storage plates are all mounted on the support. Air vent holes are distributed in the side wall of the inner cover body. The driving device is connected with the inner cover body and used for driving the inner cover body to rotate. A conduit is arranged inside the inner side wall of the inner cover body and communicated with the water tank. A plurality of mist nozzles for spraying water to the annular storage plates are arranged on the side wall of the inner cover body, and inlets of the mist nozzles are all communicated with the conduit. An air guide pipe is arranged inside the inner wall of the outer box, and a plurality of first air nozzles are arranged on the inner wall of the outer box. An air outlet pipe is arranged on the side, away from the air guide pipe, of the inner wall of the outer box. The full-automatic adjustable fresh-keeping device for fruit and vegetable transportation has good heat preservation and humidity preservation effects and can carry out exchange of air inside and outside the box.

Description

technical field [0001] The invention relates to the technical field of cargo transportation equipment, in particular to a fully automatic adjustable fresh-keeping device for fruit and vegetable transportation. Background technique [0002] At present, the fresh-keeping boxes used for keeping vegetables and fruits mainly include plastic fresh-keeping boxes and foam boxes. Plastic fresh-keeping boxes include fully-sealed incubators and ordinary plastic transfer boxes; foam boxes include fully-sealed and breathable types. Fully-sealed plastic storage boxes cannot exchange gas inside and outside the storage box, which is not conducive to the preservation of fresh agricultural products; ordinary plastic transfer boxes are not conducive to heat preservation and moisture retention in the box, and are also not conducive to the preservation of fresh agricultural products. The fully-closed foam box is the same as the plastic fresh-keeping box of the fully-closed box, which is not con...

AI Technical Summary

Problems solved by technology

Fully-sealed plastic storage boxes cannot exchange gas inside and outside the storage box, which is not conducive to the preservation of fresh agricultural products; ordinary plastic transfer boxes are not conducive to heat preservation and moisture retention in the box, and are also not conducive to the preservation of fresh agricultural products

The fully-closed foam box is the same as the fully-closed plastic fresh-keeping box, which is not conducive to the gas exchange inside and outside the box. But the insulation effect is not good, and it is also a one-time use product
