2. Description of the Related Art The value of agricultural products is lost if the time it takes to reach a place where they are consumed after they are harvested is lost. Since the high economic growth period, large production areas have been created in remote areas by policy guidance, and long-distance, mass transportation has been performed. Originally, in order to transport agricultural products that were originally unsuitable for long-distance transport over long distances, appropriate transport conditions had to be established, but conditions for agricultural transport had to be postponed.

[0003] Thereafter, due to changes in economic conditions and road maintenance, transportation conditions for agricultural products, mainly trucks, have been improved, and demand for fresh agricultural products in urban areas has increased. It has begun to be reviewed. However, since the demand for the quality of agricultural products has become more sophisticated, transportation while maintaining freshness is necessary. Also, due to the increase in the weight of remote production areas, transportation costs related to dedicated refrigerated vehicles, The distribution cost of a refrigerated warehouse in a distribution center has been significantly increased.

By the way, the low-temperature cooling during the transportation process is very effective in maintaining the freshness of fresh agricultural products if it can be completely carried out from the beginning to the end.
However, the conventional technology has a problem in continuity of temperature control, and there is a problem that the effect is reduced because the terminal is exposed to a normal temperature in a terminal or a market.
Also, multi-temperature zone (or different temperature zone) transportation, which is employed in some home delivery services, is not realistic because equipment costs are high. Therefore, in terms of total, it cannot be said that transporting agricultural products to remote places has not solved the problems in terms of both freshness maintenance technology and transportation costs.

The hard case 1 is provided with a door 2 on the front surface and has a liquefied gas inlet 3 for cooling such as liquefied nitrogen or liquefied carbon dioxide on the back surface. The liquefied gas inlet 3 does not need to be circular, and may be slit-shaped or the like. The liquefied gas inlet 3 is opened inward by pushing, and closed by a spring pressure or the like by removing the pushing force. Reference numeral 4 denotes a gas discharge port provided with a check valve. Further, on the back side of the hard case 1, a horizontally long evaporator entrance 5 into which an evaporator 12 for cooling the case described later enters, or a cold air supply pipe into which a cool air supply pipe enters. There is an entrance. The evaporator inlet 5 or the cool air supply pipe inlet is also similar to the liquefied gas inlet 3.
It is designed to open inward when pressed. In addition,
If necessary, the liquefied gas supply port 3 may be omitted, for example, by flattening the liquefied gas supply port, so that the liquefied gas supply port 3 can also be used as the evaporator inlet 5 or the cold air supply pipe inlet.

In a production center factory, predetermined pre-cooled fruits and vegetables are put in a hard case 1 or a foam case, and then the hard case 1 or the foam case is supplied to the liquefied gas supply device 7. Docking, that is, the gas supply port of the liquefied gas supply device 7 is forcibly made to enter the liquefied gas injection port 3. Then, the liquefied gas is blown out from the gas supply port to cool the inside of the case.
When this method is used, the inside of the case is reduced by one at a stretch.
It can be lowered to near 00 ° C. The cooling time varies depending on the transport distance, the transport time, the season, the designated temperature and the like, but usually, cooling for 2 to 6 minutes is sufficient. In a normal cooling state, the cooling state can be maintained for about one day, which is extremely economical. FIG. 3 is a graph showing the lapse of time and the temperature change in the case.
It can be seen that the temperature of each of the freezing zones is sufficiently controlled even after 24 hours.

As described above, by rapidly cooling the gas at the beginning of shipping, it is possible to keep the inside of the case cool for about one day without troublesome replacement of the cold storage material. Therefore, it is not necessary to use an insulated truck for transportation from the production center factory to the distribution center or the like, and the ordinary truck 8 suffices. That is, the hard case 1 may be simply placed on the carrier of the truck 8, which is simple and extremely economical. Of course, general luggage can be mixed.

At a delivery center to which the truck 8 travels, a room temperature warehouse 10 equipped with a cooling device 11 is prepared. The cooling device 11 incorporates a cooling mechanism including a compressor, a condenser, a heat exchanger, and the like. For example, a plurality of evaporators 12 are continuously and horizontally projected from a side surface thereof. Track 8
The hard case 1 which has been taken down and brought into the normal temperature warehouse 10 is opened, goods are taken out, picking,
That is, desired products are selected for each store.

In this picking operation, a belt conveyor or the like is used, but since the hard case 1 is easy to move, the cases can be brought close to each other. The operation of transferring the product to another hard case 1 can be performed within a short time. That is, since the time during which the commodity is taken out of the hard case 1 in the room temperature warehouse 10 is short, there is no problem even if the picking operation is performed at room temperature. For this reason, the conventional refrigerated warehouse is no longer necessary, and the huge costs for its installation,
Since no running cost is required, the economic effect of the present invention is immense. Moreover, since picking work can be performed at room temperature, workers do not need to wear winter clothing,
Work efficiency can be improved without harming health due to cold.

The hard case 1 in which the products are refilled by picking is docked in the cooling device 11. That is,
The back side is approached toward the evaporator 12 or one of the cold air supply pipes, and the evaporator 12 (the cold air supply pipe) is led into the evaporator inlet 5 (the cold air supply pipe inlet). By operating the cooling device 11 in this manner, the inside of the hard case 1 is cooled again, maintained at a predetermined temperature zone, and the temperature is controlled until it is shipped.

The cooling device 11 can have a function of automatically setting the inside of the hard case 1 to a predetermined temperature zone. That is, three temperature zone setting switches corresponding to three temperature zones, for example, cool, chill, freeze, etc., are installed on the hard case contact surface of the cooling device 11, while the hard case is arranged. A select switch 6 for selectively pressing the above-mentioned temperature zone setting switch is installed on the back or side surface of 1 (see Japanese Patent Publication No. 5-32669). The select switch 6 is a push type, a slide type, or the like, and is set to a predetermined temperature zone at the beginning of shipment. In the case of a foam case, since it is not usually used repeatedly, it can be a simple removal type select switch.

As described above, the present invention has many effects as described below, and is very useful as it can contribute to promoting the distribution of low-temperature preservation products. (1) The temperature in the case can be controlled regardless of the transportation distance, time, and the number of transshipments from the production center to the terminal store, etc., and freshness of fruits and vegetables can be maintained. (2) Since no refrigerated trucks or refrigerated warehouses are required for transportation and delivery, and a large investment for them is not required, transportation and delivery costs can be significantly reduced. (3) In the case of the conventional cold storage car and refrigerated warehouse, the cooling device must be operated regardless of the number of products, which is wasteful and uneconomical. There is no waste, reasonable, economical and efficient transportation. (4) Since the work in the warehouse or the factory can be performed at room temperature, the installation cost and the running cost of the refrigerated warehouse can be raised, so that not only an immeasurable economic effect is obtained but also the work efficiency is improved. It is also good for the health of the workers, since it is not necessary to wear harsh work in winter clothes.
