Box type three-bin design fresh-keeping device and method for fresh vegetables

Abstract

The invention relates to the technical field of agricultural product processing and storage, and discloses a box type three-bin design fresh-keeping device for fresh vegetables and fruits. The fresh-keeping device comprises an upper box and a lower box, wherein the upper box is a cover, and the lower box is a bin; the lower box is provided with a temperature control bin, a humidity maintaining binand a fresh vegetable and fruit storage bin; the bottom of the lower box is provided with a freezing bin for storing water or a freezing medium; the top of the lower box is provided with a storage bin; and the inner bottom wall of the storage bin is provided with strip-shaped convex strips. Fresh vegetables and fruits are placed on the top of the strip-shaped convex strips, on the one hand, direct contact with low temperature at the bottom is avoided to prevent frostbite, and on the other hand, a breathing space can be reserved to prevent mildewing; the humidity maintaining bin is arranged onthe right side of the storage bin, the bottom and four walls of the humidity maintaining bin are filled with super absorbent sponges, and sponges at the portion, connected with the storage bin, of apartition plate are designed to be in zig-zag shapes or wave shapes so as to form concave-convex sealing with the gear sponges at the corresponding part of the upper box; the zig-zag shaped sponges can be used for storing vegetables with the stems by placing the stems into the grooves; and the water absorption sponges provide water for roots and the stems of the vegetables on the one hand, and emit the water to the storage bin to keep proper humidity on the other hand, so that the vegetables are kept fresh.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing and storage, in particular to a box-type three-zone design fresh-keeping device and method for fresh vegetables. Background technique [0002] The fresh-keeping and processing of agricultural products is the continuation of agricultural production and the "secondary industry economy" in the process of agricultural reproduction. Developed countries all place post-production storage and processing in an important position for increasing the efficiency of agricultural tertiary production, except for the high added value brought by fresh-keeping and processing. , just reducing the loss in storage and transportation links can bring benefits of nearly 100 billion yuan to the society. In recent years, with the development of "Internet + agricultural products", e-commerce sales of agricultural products have been very active, but short-distance fresh-keeping transportation of fresh ...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a box-type three-zone design fresh-keeping device and method for fresh vegetables, which has the advantages of low cost, simple design and long fresh-keeping time, and solves the problem of high cost of cold chain logistics, and The existing problem of wrapping plastic wrap or putting ice cubes in foam plastic boxes only reduces the transpiration and respiration of vegetables, but cannot keep them fresh for a long period of time. The device and method of the present invention can manufacture devices of different sizes corresponding to different sizes of fruits and vegetables, and can be extended and applied to all vegetables and fruits. Preservation and transportation of fresh fruits and vegetables
