Description

[Detailed description of the invention]

[0001]

INVENTION The present invention relates, in fermentation industry and enzyme industries, supplying pressurized steam boiled raw material in solid cultivation device,
The present invention relates to a solid culture raw material processing apparatus for producing koji free of various bacterial contamination.

[0002]

Conventionally, the raw material which has been sterilized by pressurized steam boiled device is directly cooled, subjected species in the natural environment is supplied to the cooling device, it has been sent to the solid-body culture apparatus. In the soy sauce production method, a short-term and continuous method by aseptic operation can be found in Japanese Patent Publication No. 57-39625. In this method, the whole process is aseptically treated, and aseptically heat-treated, cooled, mixed, inoculated with aseptic seed koji, and forcedly ventilated with sterile humidified air to produce koji with almost no germs. There is to create. However, this method has a problem that it is difficult to treat the residue of the raw material in the apparatus and it is not possible to completely clean the material, and it is practically impossible to treat all the steps aseptically. Further, processing under completely aseptic conditions involves storing all the devices in a sterile room, which is substantially unnecessary and wasteful.

[0003]

It was boiled pressurized steam 11. devised problem you try solving Solid cultivation device raw material when performing aseptically culturing, before being supplied to the solid culture device cooling, especially bacteria contamination at the stage of with seeds Various studies have shown that the risk is high and that this point should be resolved.

[0004]

Means for Solving the Problems The present invention has been made based on the above findings, cereals such as solid culture material of pressurized steam boiled apparatus, cooling apparatus, apparatus with seed inoculation with seed,及Beauty solid body the main device of the culture device arranged in this order, these major apparatus
A solid culture material processing apparatus characterized by maintaining sterility by installing only in a clean room portion of the Chi cooling device and with the seed unit.

[0005]

[Effect] Regardless of whether the raw material is aseptically processed or the conventional method, various bacteria are killed by heat during the processing in the pressure steaming apparatus. Therefore, if sufficient care is taken in the next cooling and seeding steps, the subsequent solid culture, for example, the koji making step,
It is sufficient to carry out in the presence of conventional sterile conditioned air.

In the present invention, only the cooling device and the seeding device are installed in a clean room so that these devices are not touched by various bacteria, so that efficient sterile culture can be performed even if the sterile room is small.

[0007]

FIG. 1 is a schematic explanatory view of the present apparatus. From the upper left to the lower right of the figure, a pressurizing and steaming apparatus 1, a cooling apparatus 2, a seeding apparatus 3 for inoculating a seed fungus, and a rotary solid culture apparatus 4 for a solid culture material such as cereals are arranged in this order. The seeding device 3 is installed inside the clean room 5.

In such an apparatus, the raw material sterilized and steamed by the continuous pressure steaming apparatus 1 is cooled by a cooling apparatus 2 installed in a clean room, and is then subjected to a seeding treatment to keep a state free from contamination by various bacteria. As it is, it is incorporated into an automatic koji making apparatus, which is a rotary solid culture apparatus 4, via a transport device. As the cooling device, a net-type or steel-belt-type continuous cooling device having a structure in which air is passed through a raw material layer by a fan is used. In the automatic koji making apparatus, sterilizing treatment is performed by steam or the like before filling, and after the filling, sterile humidified air that has passed through a filter can be passed through to produce good-quality koji free from contamination by various bacteria. The cleanliness of the clean room is less than 10,000 class.

[0009]

[Effect of the Invention] In the present invention, only a cooling device and a seeding device effective for aseptic cultivation are installed in a clean room so that each device does not come in contact with various germs. Made it possible. This has made it possible to provide high quality products at low cost.
