Description

[Detailed description of the invention] The present invention relates to a clean unit for transportation and a transportation method.

Conventionally, in order to process materials such as raw materials and intermediate processing materials while keeping them isolated from germs and dust, a blower and a sterile or non-electric air filter were installed inside the walls or ceiling of the room to clean them. The process is carried out in a clean room where air is blown and circulated within the room, or as another method, a clean booth is set up inside the room and the processing is carried out within this booth. When transporting the dust-treated material to a predetermined location, a separate transport trolley is required. Furthermore, when the object is placed on a trolley in a sealed state and transported to a predetermined location, there is a risk that germs and dust contained in the outside air may pass through the sealed container and adhere to the object during this transportation. This risk of contamination also exists when, for example, pure cultured bacteria or heat-sterilized processing objects are transported in a sealed container in a room without a lean unit as described above. .

The present invention has been developed in view of the above-mentioned conventional circumstances, and it is possible to process and immerse a destroyed item in a sterile or dust-free state, and to immediately transport it as is to a predetermined location without the need for a separate trolley. The entire clean unit for conveyance is provided with a clean air flow generator consisting of a blower and an air filter for completely purifying the air flow generated by the air blower, and this generation device is used to purify the clean air flow generated by the air blower. It consists of a clean room with a completely rotating bottom wall for circulation, and wheels for movement.

Next, if I explain the operating cost, ′! 2. Operate the blower (8) of the clean air flow generator M (11) to flow clean air into the clean room (5) and maintain the inside of the clean room (5) in a sterile or dust-free state at positive pressure. In this way, the objects to be processed af can be accommodated in the Western-style room (5) and processed in a sterile or dust-free state.Furthermore, when necessary, when transporting the objects to a predetermined location, it is possible to carry them separately on a trolley as in the past. It is convenient because you can immediately transport it as is without having to prepare it and transfer it to this.

In this case, there is a risk that bacteria and dust in the air may adhere to the workpiece a in the clean room (5) during this transportation. In addition, there is a similar risk of contamination when a sterile workpiece that has been heat sterilized or sterilized separately outside is housed and transported.

The present invention uses the above-mentioned clean unit for transport of the present invention to provide a transport method free from the above-mentioned risk of contamination.
The present invention is characterized in that the object to be processed is accommodated in the clean chamber of the clean unit for conveyance, and the object is conveyed under the operation of the clean unit for conveyance.

Next, one embodiment will be explained in detail.

Examples demonstrate the present invention in the cultivation of enoki mushrooms.
