Problems solved by technology

The existing fresh-keeping technologies often affect the quality of fruits and vegetables to varying degrees during the fresh-keeping process, or the cost of fresh-keeping is too high to be widely promoted. The existing methods of fruit and vegetable transportation include: refrigerated transportation, preservative soaking Transportation, fresh-keeping bag sealed transportation and fresh-keeping coated transportation, these methods all have many shortcomings: refrigerated transportation often causes browning inside the fruit, wet cracking, softening of the skin, uneven ripening, poor appearance after ripening, and some fruits are damaged. After refrigerating, it cannot even be post-ripened, and the taste will change greatly. Refrigeration will also cause some thermophilic bacteria, molds and yeasts to grow, destroying the stored fruits and vegetables; the disadvantage of transportation after soaking in preservatives is the problem of drug residues. The preservatives used include Tekodol, Prochloraz, Imazalil, Prodigyne, Etoconazole, Carbendazim, Benite, etc., as well as calcium salts and 1-MCP that regulate postharvest physiological activities. It will have an adverse effect on human health; due to the use of PVC plastic sealed bags for fresh-keeping bags, its non-degradability and air-tightness will bring a lot of white pollution and dehydration and rot of a large number of fruits and vegetables during the transportation of fruits and vegetables; after fresh-keeping coating The main components of the coating film during transportation are compounded by paraffin wax, palm wax and microcrystalline wax. In addition, there are shellac, food-grade synthetic resin, etc. This kind of plastic wrap can prevent fruit dehydration, but the process is cumbersome and expensive.
[0004] The patent document with the publication number CN 2380459Y discloses a fruit and vegetable fresh-keeping transport vehicle, which adopts ozone for sterilization and disinfection on the basis of refrigeration and fresh-keeping. Although the fresh-keeping effect is improved, the structure of the whole fresh-keeping vehicle is complex, high power consumption, and this document does not disclose the specific concentration of ozone used; the patent document with publication number CN 1579175A discloses a fruit and vegetable fresh-keeping storehouse. Although ozone is also used for sterilization and disinfection, it is more suitable for fixed warehouses, not suitable for moving transport carriages

Embodiment 1

[0044] Embodiment one: see figure 1 , image 3 , Figure 5, Figure 7, Figure 8, Figure 10~ Figure 12 , in the figure, the fresh-keeping compartment for fruits and vegetables includes a compartment 1, the inner surface of the compartment 1 is provided with an insulating layer 2, the inner surface of the insulating layer 2 is provided with an inner compartment 13, and the outer wall of the compartment 1 is equipped with a fresh-keeping machine 3 for fruits and vegetables. The air outlet pipe of the machine 3 communicates with the interior of the fruit and vegetable fresh-keeping compartment, and the inner surface 25 of the top plate of the compartment is fixed with an ozone delivery pipeline network 5, and an air outlet 6 is opened on the ozone delivery pipeline network 5, and the air outlet pipe of the fruit and vegetable fresh-keeping machine 3 is connected to the The air inlet 7 of the ozone delivery pipeline network 5 is connected, and three fine atomization nozzles 11 and ...

Embodiment 2

[0054] Embodiment two: see figure 1 , image 3 , Figure 6, Figure 7, Figure 8, Figure 10~ Figure 12 , the fruit and vegetable fresh-keeping vehicle is a semi-trailer truck, the number in the figure is the same as that of Embodiment 1, and the representative meaning is the same, and its working process is also basically the same, and the similarities will not be repeated. The difference is: the ozone delivery pipe The structural shape of the road network 5 is different from that of the first embodiment; the numbers of the fine atomizing nozzles 11 and the electric fans 8 are four respectively.

Embodiment 3

[0055] Embodiment three: see figure 1 , Figure 4 , Figure 5, Figure 7, Figure 8, Figure 10, Figure 13 ~ Figure 14 , the fruit and vegetable fresh-keeping vehicle is a semi-trailer truck, the number in the figure is the same as that of Embodiment 1, and the representative meaning is the same, and its working process is also basically the same, and the similarities will not be repeated. The difference is: ozone detector and the number of humidity detectors is respectively three, respectively fixed with ozone detector 4-2, 4-1 and 4. Humidity detectors 12-2, 12-1 and 12 are respectively fixed on the inner surface 22 of the left plate of the car body, the inner surface 23 of the right plate of the car body and the inner surface 21 of the rear plate of the car body; The power supply terminals of ozone detector 4-2, 4-1 and 4 are connected, and the output terminals of ozone detector 4-2, 4-1 and 4 are connected with the signal input end of AC contactor through electromagnetic re...

Abstract

The invention relates to a fruit and vegetable transporting and preserving method by using ozone as well as a fruit and vegetable preserving carriage and a fruit and vegetable preserving vehicle. The fruit and vegetable transporting and preserving method is that the ozone is injected into a thermal-insulating fruit and vegetable storage space with a certain shape and volume and not sealed completely; proper ozone density and proper humidity are remained in the space which is not sealed completely, the humidity is maintained at 50-95 percent and the ozone density is maintained at 3ppm-25ppm. The fruit and vegetable preserving carriage comprises a carriage body; a thermal-insulating layer is arranged on the internal surface of the carriage body; the escape pipe of a preserving machine installed on the external wall of the carriage body is communicated with the intake pipe of an ozone delivery pipe network fixed on the inner surface of the roof plate of the carriage; an electric fan and a fine atomizing spray head are also fixed on the inner surface of the roof plate of the carriage; at least one ventilation silicon window communicated with the carriage body is arranged on the flank of the carriage body. The fruit and vegetable preserving vehicle comprises a fruit and vegetable preserving carriage. The invention provides a fruit and vegetable preserving carriage and a fruit and vegetable preserving vehicle with sound preserving effect and low power consumption.
