Problems solved by technology

At present, the fresh-keeping box made of simple foamed plastic is generally used in the transportation process, which is composed of a box body and a box cover. Fruits and vegetables are put into the box body, the box cover is covered, and the joint part of the box body and the box cover is sealed with transparent tape. Just seal it; some will add ice cubes to keep fresh, but the ice cubes are easy to melt and difficult to replace. The melted water soaks the product, causing microbial infection; some even directly transport it with a large truck without any fresh-keeping measures measure
Although refrigerated trucks have existed for a long time, they are rarely used in the circulation of fresh fruits and vegetables due to reasons such as high cost and unstable refrigeration effect.
As a result, the loss in the circulation of fresh fruits and vegetables is serious, the quality deteriorates drastically, and the loss rate exceeds 50%, or even higher, which brings huge losses to producers and consumers, and also hinders the circulation of fresh fruits and vegetables.

Embodiment 1

[0025] Put 20% ethanol solution (the rest is sea water) in the cold storage at -20°C for 12 hours, inject it into the aluminum box 2, tighten the bolt 3, insert it into the interlayered foam fresh-keeping box (40cm*35cm*35cm), up and down and Put a plate on each of the 4 sides, a total of 6 sides, the size of the plate is 25cm*25cm*25cm; after insertion, cover it tightly with a foam cover, and seal it with tape after fixing.

[0026] The freshly picked raspberries of 2.5kg are put into the fresh-keeping box, fasten the box cover 4, and seal. The whole process was carried out in a refrigerator at 2-4°C. The control is to place an ice pack of equal weight on the bottom of the fresh box.

[0027] The above treatments (three replicates for each treatment) were placed in a constant temperature incubator and kept at 25°C. Use a temperature probe to measure the internal temperature of the fresh-keeping box every 6 hours, observe the change of temperature, and finally measure for 36...

Embodiment 2

[0031] Put 35% ethanol solution (the rest is seawater) in the cold storage at -20°C for 12 hours, pour it into an aluminum box, tighten the bolts, and insert it into a foam preservation box (40cm*35cm*35cm) with interlayers. Put a flat plate on each of the 6 sides, the size of the flat plate is 25cm*25cm*25cm, cover it tightly with a foam cover after insertion, and seal it with tape after fixing.

[0032] Put 2.5kg of freshly picked raspberries into a fresh-keeping box, fasten the box cover, and seal it. The whole process was carried out in a refrigerator at 2-4°C. The control is to place an ice pack of equal weight on the bottom of the fresh box.

[0033] The above treatments (three replicates for each treatment) were placed in a constant temperature incubator and kept at 25°C. Use a temperature probe to measure the internal temperature of the fresh-keeping box every 6 hours, observe the change of temperature, and finally measure for 36 hours. Open the box and calculate th...

Embodiment 3

[0036] Put 20% ethanol solution (the rest is seawater) in the cold storage at -20°C for 12 hours, pour it into an aluminum box, tighten the bolts, and insert it into a foam preservation box (40cm*35cm*35cm) with interlayers. Put a flat plate on each of the 6 sides, the size of the flat plate is 25cm*25cm*25cm, cover it tightly with a foam cover after insertion, and seal it with tape after fixing.

[0037] Put 2.0kg of freshly picked leeks into a fresh-keeping box, fasten the lid, and seal it. The whole process was carried out in a refrigerator at 2-4°C. The control is to place an ice pack of equal weight on the bottom of the fresh box.

[0038] The above treatments (three replicates for each treatment) were placed in a constant temperature incubator and kept at 25°C. Use a temperature probe to measure the internal temperature of the fresh-keeping box every 6 hours, observe the change of temperature, and finally measure for 36 hours. Open the box and calculate the rotting ra...

Abstract

The invention relates to a fresh-keeping box, in particular to a fruit and vegetable fresh-keeping box. The fruit and vegetable fresh-keeping box comprises a box body and is characterized in that the six side faces of the box body are all of hollow structures, and aluminum boxes are arranged in the hollow structures and contain seawater and absolute ethyl alcohol. The fruit and vegetable fresh-keeping box is simple in structure and convenient to use, an ethyl alcohol and seawater compound is adopted as a refrigerant, cold accumulation capacity is high, the effect of cooling fresh fruits and vegetables is good, and low temperature can be kept for a long time, which is suitable for dynamically keeping the fruits and vegetables fresh.

Description

(1) Technical field [0001] The invention relates to a fresh-keeping box, in particular to a fresh-keeping box for fruits and vegetables. (2) Background technology [0002] my country is a big producer of fruits and vegetables. For a long time, due to the backward promotion of fresh-keeping technology, a lot of losses have been caused, and the general loss rate is as high as about 25%. Under the current situation, consumers order long-distance fresh fruits and vegetables through the Internet, that is, online shopping has become fashionable. During the process of fruit and vegetable production units transporting fresh fruits and vegetables from the base to consumers, fresh fruits and vegetables generally experience long-distance transportation and severe vibration, as well as temperature rise in the packaging environment due to breathing accumulation. The basic means of fresh-keeping of fruits and vegetables is still based on low temperature, supplemented by certain physical ...
