Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for storing and cooling agricultural products immediately after harvesting,
Concerning a refrigerated transportable container for agricultural products used for shipping and transporting agricultural products to their destination while maintaining their freshness.

[Conventional technology and its problems]

Trucks, freight cars, etc. for transporting refrigeration and frozen products equipped with refrigeration or cooling machines are generally expensive. In addition, these have the advantage of being able to quickly obtain cold and heat and making it easy to adjust the temperature, but since running costs and maintenance costs are high, when transporting agricultural products, unless it is a product with particularly high added value, The current situation is that it is not profitable.

Furthermore, trucks, freight cars, etc. equipped with this freezing or cooling machine are unsuitable for refrigerated transportation of agricultural products because they use forced convection of cold air using fans, which may remove moisture from the refrigerated items and impair quality. be.

The present invention eliminates such problems and allows vegetables,
The purpose of the present invention is to provide a container suitable for refrigerated transportation of ordinary agricultural products such as fruits and flowers.

[Means for solving problems]

The structure of the container of the present invention that achieves the above object is as follows.

The container body a has a ceiling 1 having a heat insulating structure,
A cold storage room 7 is surrounded by a floor 2 and front, rear, left and right side walls 3 to 6.

The container body a is provided with two types of ice storage chambers for storing ice blocks such as natural ice collected from the sea, lakes, rivers, etc., or artificial ice made by compressing and molding snow. One of the ice storage chambers b is provided below the ceiling 1, and consists of a plurality of ice storage chambers separated by partition plates 17 and communicating with each other through holes 19 in a shallow flat box 16. It is formed by dividing small ice chambers 18, and a plurality of ice inlets 8 of each of the small ice chambers 18 are provided through the ceiling 1, and each is provided with a heat insulating lid 9 which can be opened and closed. The other ice storage chamber c is provided along at least one of the front, rear, left and right side walls 3 to 6, has a deep vertical shape, and has an ice inlet 10 opened at its top surface, which is connected to the ice storage chamber b. The opening is near the bottom. When the volume of the cold storage chamber 7 is sufficiently large, it is desirable to provide the ice storage chamber c on the entire wall surface other than the door.

A floor plate 20 is stretched above the floor 2 to form a flat chamber 11, and a cold water pipe d is inserted into the chamber 11.
This cold water pipe d and the ice storage chambers b and c are connected by water supply pipes 12 and 13 that supply ice melting cold water to each chamber.

[Effect]

Ice blocks are placed in the ice storage chambers b and c, and the produce e in the cold storage chamber 7 can be kept cool at around 0° C. by the cold heat. A cold storage temperature close to 0°C is most ideal, especially for keeping produce fresh.

Agricultural products can be stored in the containers of the present invention and transported by trucks, freight cars, etc. from the place where the agricultural products are harvested to markets, storage warehouses, etc. in the most economical manner.

〔Example〕

The invention will now be described in detail with reference to the illustrated embodiments.

A is a container main body of a required size that can be loaded onto a truck or the like and transported, and a cold storage room 7 is surrounded by a ceiling 1, a floor 2, and front, rear, left, and right side walls 3 to 6. The ceiling 1, the floor 2, and the front, rear, left, and right side walls 3 to 6 all have a heat-insulating structure, which is achieved by using a single or double layer of heat insulating material such as urethane or styrofoam between the exterior iron plate and the interior stainless steel plate. I will intervene.

Although not shown in the drawings, the ceiling 1, the floor 2, and the front, rear, left, and right side walls 3 to 6 are stretched by appropriate means to a structural frame assembled with a steel frame made of H-shaped steel, for example, and constitute the container body a. This is what we are doing. Further, in this embodiment, the front side wall 3 is independently formed as a door, and this is hinged to the front end of the right side wall 6 with a hinge 14, so that the front entrance can be opened and closed.
15 is a closing door locking tool.

b is an ice storage chamber suspended and fixed to the lower side of the ceiling 1;
7 to divide vertically and horizontally into a plurality of small ice chambers 18, and each small ice chamber 18 is separated by a partition plate 17.
They are connected by a hole 19 provided in the.

A plurality of ice inlets 8 are provided through the ceiling 1 at positions facing each of the ice compartments 18, and each is provided with an insulating lid 9 that can be opened and closed.

C is a deep vertical ice storage chamber provided along the inner surface of the rear wall 4, and has an ice inlet 10 opened on the top surface.
is opened to the cold storage chamber 7 near the bottom of the ice storage chamber a.

Reference numeral 11 denotes a flat chamber formed by a floor 2 and a floor plate 20 stretched above the floor 2, and a cold water pipe d is meanderingly connected to the chamber 11. 12 is the ice storage chamber b
13 is a water pipe connecting the bottom of one of the small ice chambers 18 and the inlet 21 of the water pipe d; 13 is a water pipe connecting the bottom of the ice storage chamber c and the inlet 21 of the cold water pipe d; A valve 23 is provided at the outlet 22 of d.

The container of the present invention having the above configuration includes an ice storage chamber b,
Ice cubes are put into the ice storage compartment b, and the produce e in the cold storage room 7 is transported to the destination while being kept cool by the cold heat. , ice cubes are placed in the ice storage chamber c through the ice inlet 10 opened in the cold storage chamber 7, and agricultural products e are taken in and out of the cold storage chamber 7 by opening and closing the front wall 3, which serves as a door. . Further, the ice melting cold water stored in the ice storage chambers b and c stored in the cold water pipe d normally contributes to cooling the empty room 11 of the floor 2, but the valve 23 is opened to drain the water if necessary.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the ceiling, floor, front, rear, left, and right side walls surrounding the cold storage room have a heat insulating structure, and the ice storage room has a shallow flat bottom below the ceiling; The cold energy of the ice cubes stored in the deep vertical ice storage chamber on at least one of the front, rear, left, and right side walls allows the produce in the cold storage chamber to be kept cool at near 0° C., which is the optimum temperature for keeping the produce cool.

In addition, the ice melting water in both ice storage chambers can be guided to cold water pipes connected to the flat empty space formed on the floor to cool the empty space. Even if it were to be placed on hot ground, the bottom part would be double-insulated by an air-conditioned empty room and an insulated floor, causing the temperature of the cold storage room to rise rapidly. There is no such thing.

Moreover, since the container of the present invention uses ice blocks as its cooling heat source, it can perform the above-mentioned cold storage at the lowest cost. It's an economical thing.

Therefore, the container of the present invention is provided in each farmer, and the harvested agricultural products are immediately kept cool to suppress the generation of respiratory heat peculiar to the agricultural products, and the containers are transported by truck, freight car, ship, etc. The agricultural products can be delivered to the market or to a storage warehouse in a fresh state.
