Fruit and vegetable fresh-keeping box and fresh-keeping method

Abstract

The invention relates to a fruit and vegetable fresh-keeping box which is a cylindrical box with a circular opening on a top surface and a heat-insulating cover covering on the opening, wherein the heat-insulating cover and the box are made of heat-insulating plates; iron sheets are arranged on the interior and exterior and foam heat-insulating layers are arranged in the middle; air holes are formed in the middle parts of the heat-insulating cover and the bottom of the box; a water outlet is arranged at the bottom of the box; a funnel-shaped pored net is arranged at the bottom of the box; a conical double-layer grid is arranged in the middle of the box; the size of the opening on the conical double-layer grid is equal to the size of the heat-insulating cover; ice cubes are arranged in the middle of the conical double-layer grid. The invention also relates to a process applying the fruit and vegetable fresh-keeping box to the fresh-keeping of fruit and vegetables. The fruit and vegetable fresh-keeping box has the advantages that (1) the fruit and vegetable fresh-keeping box can be used for insulating and ventilating and can preferably keep the quality characteristics of fresh agricultural products; (2) the low-temperature storage of the fruit and vegetables can be kept, the low-temperature fresh-keeping of the fruit and vegetables can be kept, and meanwhile, the harm to the quality of the fruit and vegetables caused by the gathering of condensation water formed by the water vapor released under the effect of the respiration of the fruit and vegetables is prevented; (3) the fruit and vegetable fresh-keeping box can be reused and belongs to an environment-friendly product.

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 bo...

AI Technical Summary

Problems solved by technology

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
