Description

Fruit and vegetable fresh-keeping carton

Technical Field

The utility model relates to a fruit vegetables fresh-keeping technical field, in particular to fruit vegetables carton that keeps fresh.

Background

In the present life, fruits and vegetables are indispensable food in life, as is well known, the nutritional value of fresh fruits and vegetables is high, but the storage and transportation are difficult, especially under the condition that a plurality of fruits are stored and transported together in the transportation process, a great amount of ethylene is often released by some mature fruits, and the ethylene can accelerate the maturation and the decay of the fruits, so that the statistics on how to reduce the concentration of the ethylene in the storage environment and slow down the maturation and the decay of the fruits are the problems which are urgently needed to be solved at present are carried out, and the research on the preservation technology has important significance on reducing the loss of fruits and vegetables caused by the decay. In particular to the links of storage, transportation, sale and the like after picking fruits and vegetables. In the aspect of fruit and vegetable preservation in the prior art, common technologies comprise modified atmosphere packaging, low-temperature refrigeration and the like, a large amount of equipment is needed, the cost is high, and the preservation effect is poor. In recent years, a coating preservation technology is used, namely an edible film with a preservation effect is coated on the surface of fruits and vegetables, but the coating preservation technology also has a plurality of problems, such as the coating thickness is not easy to control; too long drying time is easy to breed microorganisms; packaging containers and the like are still needed after coating.

Chinese patent with publication number CN207046089U discloses a fruit transport case, the power distribution box comprises a box body, box internal rotation is connected with medicine storage box, be equipped with the cartridge bag that is used for detaching the ethylene gas in the medicine storage box, set up the air vent in order to realize absorbing the ethylene gas on the medicine storage box, this kind of fruit transport case can absorb the interior ethylene of box, but not set up the structure of absorption oxygen in the box, so the fruit vegetables can carry out a large amount of respiration, still can accelerate rotting speed after the fruit vegetables carry out respiration, consequently this kind of fresh-keeping case can't keep the interior low concentration of oxygen of box in the in-service use process, can't carry out fresh-keeping effect to fruit vegetables better through slowing down fruit vegetables respiration.
