Description

The present invention relates to a container for transporting fresh food such as food and plants by forming an electrostatic field atmosphere in a cold storage container equipped with a cooler.

For example, as disclosed in Patent Document 1, an electrostatic field is formed in a refrigerator, and a method for refrigerated storage of fresh food products or the like in this atmosphere for a long period is widely known. As the electrostatic field forming means, a high-voltage electrostatic transformer is used, one pole on the secondary high-voltage side is insulated, and the other pole is connected to a shelf or case of a conductive metal material. Thereby, negative electrons due to electrostatic induction are applied, and the fresh food placed on the shelf can be refrigerated and stored in an electrostatic field atmosphere. In this case, the negative-electron generation condition is that the current value on the primary side of the high-voltage electrostatic transformer 100V is 0.02 A to 5.0 A per 1 m ^{2 of the} electrode, and the secondary side voltage satisfying the primary side current value is 500 V to 20000V.

In the electrostatic field atmosphere formed in the refrigerator, it is usually stored in a temperature range of 5 ° to -1 °, but it does not freeze even at a low temperature of about -3 ° C. For this reason, it can be stored in a fresh state for a long period of time without causing cell destruction during freezing, and is a very suitable storage method for storing fresh food products.

  Even if it becomes possible to preserve fresh products such as seafood, meat, vegetables, fruits, and flower buds for a long period of time by electrostatic field treatment, this form greatly collapses at the stage of distribution, resulting in a problem that the freshness is significantly reduced. Currently, a cold container equipped with a refrigerator is generally widely used and maintains a certain level of freshness in the transportation of fresh food, but is significantly different from storage in an electrostatic field atmosphere.

In this regard, there may be a case where an electrostatic field atmosphere is formed in the cold container, but a structurally difficult problem arises. In other words, in order to form an electrostatic field space, it is necessary to install a control box equipped with an electrostatic field generating power source, etc., but installing it outside the cold storage container or in an electrostatic field atmosphere is a safety problem. The installation location will be significantly restricted.

  In view of the above situation, the inventor finally completed the present invention as a result of earnest research. The feature of the present inventor is that the peripheral surface and the bottom surface are electrically conductive inside the cold storage container mounted on the truck. A storage part that is formed of a panel and is connected to an electrostatic field generating power source to form an electrostatic field space is installed on the wall surface and floor surface of the cold container through an insulator, and the electrostatic field generating power source is This is to install a control box that is housed, and is provided with a partition panel that constitutes one wall surface of the cold storage container and divides the inside into two.

  Here, the “conductive panel” referred to in the present specification is a member that forms a space for storing fresh food inside a cold container, and is a member that forms an electrostatic field atmosphere inside. This conductive panel is attached to the wall surface and floor surface of the cold storage container via an insulator such as an insulator and surrounds the peripheral surface and the bottom surface to form a storage portion constituting an electrostatic field space. In order to make it easy to store fresh food in the storage unit, a shelf may be provided in the storage unit or a separate storage tool may be installed.

  The “partition panel” is a member that partitions the inside of the cold insulation container into two and constitutes the wall surface of the cold insulation container. By providing a storage portion on one side of the space partitioned by the partition panel, the space is configured as an electrostatic field space. And the control box which accommodated the electrostatic field generation power supply is installed in the state isolated from the electrostatic field atmosphere on the other side of the partition panel.

  Since the cold storage container is basically provided with an open / close door such as a double door on the rear side, usually a storage part is formed in the space on the front side (truck cabin side) of the partition panel, and the space on the rear side Is used as a conventional cold storage space. In this case, it is necessary to provide an opening / closing door for the accommodating portion on the side surface of the cold container.

The operation switch of the electrostatic field generation power supply and the lamp that displays the operation status, etc. are provided in the control box, especially in the dash panel of the truck cabin, so that the driver can operate it during transportation and transmit information It becomes effective in being able to do it.

In the present invention, by providing the control box containing the electrostatic field generating power supply in the partition panel that partitions the inside of the cold storage container, the electrostatic field generating power generating high voltage can be safely provided in the cold storage container, It is possible to ensure the electrostatic field treatment in the transport stage. As a result, fresh products preserved by electrostatic field treatment can be transported under almost the same conditions, and a decrease in freshness in the market can be reduced.

This invention solved the said subject by providing the control box which accommodated the electrostatic field generation power supply in the partition panel which partitions off the inside of a cold storage container.

The control box 8 is provided. Thereby, the electrostatic field generating power source can be installed inside the container and isolated from the electrostatic field space. In this example, an insulating resin sheet 9 such as an ABS resin is attached to the wall surface and the floor surface as shown in FIG. 3 in order to ensure insulation against the high potential of the electrostatic field generating power source. The insulator 5 is attached via a stainless steel plate 10.
