Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for transporting fresh foods while maintaining their freshness.

Traditionally, when transporting foods such as vegetables from production areas to consumption areas, they are loaded into van bodies equipped with cooling and heating equipment.

The vehicle was transported while keeping the inside of the van body at a low and constant temperature.

However, as shown in Figure 1, the cooling device circulates the air inside the 5VC pan body 12 to cool the air.

During air cooling, moisture in the air condenses and is removed, so the cold air inside the van body 2 dries. As a result, the moisture in the fresh food is dissipated into the cold air, reducing the freshness of the fresh food.

The present application was invented in order to solve the above-mentioned problems.

In other words, the present invention is characterized in that a bun body having a heat-retaining structure for transporting foods, etc. is provided with a cooling device for keeping the inside of the bun body at a desired temperature, and a humidifying device for keeping the humidity inside the bun body at a desired temperature. The gist is how to transport fresh foods.

According to the present application, since a humidifying device for humidifying the inside of the bun body is disposed in the bun body, the cold air inside the bun body is prevented from absorbing moisture in the fresh food, and the freshness of the fresh food can be maintained. There is.

A first embodiment of the present invention will be described below with reference to the accompanying drawings. Note that parts that are the same as those in the conventional example are designated by the same reference numerals.

In FIG. 2, 2 is a van body mounted on an l-rack 1, and 3 is mounted on the front end of the van body 2.

A cooling device 4 cools the inside of the bun body 2, and a cargo space 4 is used to load fresh vegetables assembled into a house shape inside the bun body 2 with a pipe 4'. The luggage compartment 4 is made to have an appropriate distance from the inner wall of the van body 2, and the luggage compartment 4 is covered with a vinyl material 5 to be isolated from the cold air circulating inside the van body 2.

Also, if the shielding material is a material with good thermal conductivity such as glass.

Any material may be used.

Reference numeral 6 denotes a known humidifier disposed at the front end inside the van body 2. The humidifier 6 operates continuously or automatically using a known timer or the like. .

Although not shown, an operating switch may be provided in the driver's seat to operate the humidifier 6, and the driver may operate the humidifier 6 at his/her discretion.

7 is a conduit that guides the gas atomized by the humidifier B into the luggage compartment 4, and is connected to the pipe 4' forming the luggage compartment 4, and the gas is atomized from the nozzle 4'' provided in the pipe 4'. The gas is blown out to maintain the humidity in the luggage compartment 4.

In this example, when the temperature inside the bun body 2 was set to 0 to 5°C and the humidity to 85 to 95°C, the freshness of the vegetables could be effectively maintained.

According to this embodiment, the cold air inside the van body 2 and the vinyl material 5
Since the inside of the luggage compartment 4 covered with the interior of the luggage compartment 4 is isolated from the interior of the luggage compartment 4, the interior of the luggage compartment 4 is cooled by the cold air inside the van body 2 cooled by the cooling device 3 via the vinyl material 5.

In addition, since sufficient humidity can be maintained by the humidifier B, a decrease in humidity due to operation of the cooling/heating device 6 can be prevented.

Therefore, water dissipation from fresh foods is prevented and the freshness of fresh vegetables can be ensured.

Next, a second embodiment will be explained with reference to FIG. Figure 3 shows a system that atomizes water by using compressed air owned by large trucks, etc., instead of the well-known humidifier B shown in Figure 2.
This is to maintain the humidity inside.

8 is a water tank disposed inside the van body, 9 is a pump that pumps the water in the water tank through a pipe 11 to a nozzle 10 for atomization, and 12 is a pipe i4, 15 for transporting compressed air from the air tank 13. The solenoid valve 16 that supplies the power to the nozzle 10 through the solenoid valve 16 is a manual switch installed in the driver's seat for simultaneously operating the pump 9 and the solenoid valve 12 using a power source 17.

In operation, when the driver operates the switch 16, the pump 9 and the solenoid valve 12 are activated simultaneously, and water in the water tank 8 and air in the air tank 13 are force-fed to the nozzle 10 and atomized.

According to this embodiment, since the device for ejecting vibrations has a simple structure, it has the effect of being cheaper than using an existing humidifier.

The third embodiment will be explained with reference to FIG. 2 is a van body equipped with a cooling device 3 at its front end; 18 is a water tank with a built-in water pump disposed at the front end inside the pan body 2;
Reference numeral 19 is a running water pipe that is installed in the ceiling corner of the van body 2 and allows the water pumped from the water tank 18 by the water pump to flow through the spout 20 along the inner wall of the van body. It is a groove for receiving.

4. The water pump is driven by the operation of a manual or timer switch installed on the driver's seat (not shown).

The water in the water tank is fed under pressure to the water pipe 19.

According to this implementation, as shown in FIG.
In addition, the structure of the humidifier is simple and inexpensive.

Examples 1 and 2 will be explained along FIG. 5 as a fourth embodiment.
2 is a van body equipped with a cooling device 6 at the front end and partitioned in the middle by a heat insulating material, with a front chamber 23 as a freezing chamber and a rear chamber 24 as a structure in which fresh food according to the present invention is placed;
The new vehicle is designed to maintain the freshness of perishable foods while transporting frozen foods in the same way as before.

In addition, as a method for maintaining the freshness of fresh foods, the above-mentioned Examples 1, 2, and 5 shall be used as appropriate, taking into consideration the purpose of use, cost, etc.
