Air-conditioning temperature-reducing and light-tight preservation box for delivering or storing vegetables in short term

Abstract

The invention discloses an air-conditioning temperature-reducing and light-tight preservation box for delivering or storing vegetables in short term. The air-conditioning temperature-reducing and light-tight preservation box comprises a box body and a box cover airtightly covering on an upper opening of the box body; an insulating layer is coated on an inner side wall of the box body; an isolating bracket is arranged at the bottom of the inner side of the box body; a through hole is formed on the isolating bracket; a fluid refrigerant bag is arranged at the bottom inside the box body on the lower part of the isolating bracket; a plurality of air holes are formed on two symmetrical side surfaces of the box body; a selective ventilated membrane coats on the plurality of air holes on the inner side of the box body; and a reflecting coating is arranged on the outer surface of the box body. The air-conditioning temperature-reducing and light-tight preservation box has the advantages that: the preservation box has good function of protecting the vegetables, and is repeatedly used, extrusion resistant, and convenient to load and unload; the tightness of the box body and the selective ventilated membrane which is adhered to the holes on the two side surfaces have good air-conditioning function; by adjusting the number of the holes, the ventilating area of the selective ventilated membrane is adjusted, so that the aim of changing the gas components in the preservation box is fulfilled; the vegetable ageing is prevented; and the repeatedly used ice bag can realize the function of reducing the temperature.

Description

technical field [0001] The invention relates to a special fresh-keeping equipment for vegetable circulation and fresh-keeping, in particular to a controlled-atmosphere cooling and light-proof fresh-keeping box for distribution or short-term storage of vegetables. Background technique [0002] Picked vegetables are living organisms. With a series of mature and aging changes centered on respiratory metabolism, the quality of vegetables declines and eventually deteriorates. At present, the common methods of vegetable storage and preservation mainly include: (1) storage in simple storage places. Its characteristic is to make the best use of natural cold sources and other favorable natural geographical conditions, such as storage in cave dwellings and caves; (2) storage in cold storage. Its characteristic is that according to the type and variety characteristics of vegetables, mechanical refrigeration is used to provide suitable temperature and adjust humidity conditions for sto...
