Multifunctional fresh-keeping device for vegetable transportation

Abstract

The invention provides a multifunctional fresh-keeping device for vegetable transportation. The multifunctional fresh-keeping device for vegetable transportation comprises a box, a driving device, a plurality of racks used for storing vegetables, a control device and a gas concentration detection device. Ice water is placed in a water chamber. An air inlet pipe is arranged at the bottom of the water chamber. A first air nozzle is arranged at the end, located in the water chamber, of the air inlet pipe, and a first flow valve is arranged in the first air nozzle. An air guide pipe is arranged in a fresh-keeping chamber, and an inlet of the air guide pipe is communicated with the water chamber. A plurality of second air nozzles are distributed on the air guide pipe, and second flow valves are arranged in the second air nozzles. The driving device is used for driving the air guide pipe to rotate. An air outlet pipe is arranged at the top end of the fresh-keeping chamber, a third air nozzle is arranged at the end, away from the box, of the air outlet pipe, and a third flow valve is arranged in the third air nozzle. The racks are detachably mounted on the inner wall of the fresh-keeping chamber. The control device is connected with the first flow valve, the second flow valves, the third flow valve, the driving device and the gas concentration detection device. The multifunctional fresh-keeping device for 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 vegetable transportation equipment, in particular to a multifunctional fresh-keeping device for 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 conducive to the gas...

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
