BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fumigation warehouse for treating fumigants such as fruits and vegetables with fumigant gas, and more particularly to enabling fumigation treatment in the warehouse while the fumigants are contained in a container. It is about the fumigation warehouse.

[0002]

2. Description of the Related Art Food products such as fruits and vegetables imported in large quantities are
Based on the imported phytosanitary regulations aimed at exterminating pests, fumigation of a certain standard is obligatory.

When such fruits and vegetables have been imported by shipping or the like, conventionally, the fruits and vegetables packed in a container that are unloaded from a boat are carried by a trailer to a fumigation warehouse built near the port, and then stored in the container. Vegetables and fruits are taken out from the container and loaded into the fumigation warehouse. Then, in the fumigation warehouse, a constant fumigation process is performed.

That is, the conventional fumigation warehouse needs to be operated under strict regulation, and therefore the warehouse itself has a function and a structure as a fumigation apparatus so that the fumigant gas can be controlled.

However, in the usual warehouse fumigation, since it is necessary to load and unload fumigants such as fruits and vegetables from the container, the merit of container leasing is impaired, but the pain of the fruits and vegetables becomes severe. have.

In order to solve these drawbacks, a plurality of containers are carried into a fusible warehouse capable of being sealed while the fruits and vegetables are stored in the containers, and fumigant gas is fed into each container to temporarily fumigate. The method of processing is adopted.

That is, fumigant gas is sent from the outside of the warehouse to the inside of the warehouse via a pipe or a hose, and a plurality of gas stirring fans are attached to the inside of the warehouse so that the fumigant gas has a constant concentration in the warehouse. There is known a fumigation warehouse for container packing having a structure in which a gas supply pipe is provided inside the container in order to make the fumigant gas inside the container uniform and a blower fan for feeding the fumigant gas into the gas supply pipe is provided.

[0008]

However, in the fumigation warehouse for container packing as described above, since the gas supply pipes are provided inside the respective containers, the structure becomes complicated and the cost is high. In addition, there is a problem that it may cause a failure.

The present invention has been made in view of the above-mentioned problems, and even in a fumigation warehouse capable of fumigating a container, it is inexpensive because of a simple structure.
Moreover, the purpose is to provide a fumigation warehouse with few failures.
