The present invention provides a new and useful simple koji making device that is equipped with one or more rotationally driven rotating culture beds and that saves labor and improves the quality of koji making work.

Next, an example of installing a rotating culture bed in which the apparatus of the present invention is divided into a first-stage koji-making stage and a second-stage koji-making stage will be described.

In this apparatus, an insulated koji chamber, etc. is equipped with an automatic temperature and humidity adjustment device, and the operation of this automatic temperature and humidity adjustment device ensures that the room is always maintained at the temperature and humidity required for koji production. In addition, by introducing outside air, low enthalpy air can be used effectively. A rotary culture bed that is rotationally driven is provided in such a room, and a screw as a conveying means and a care device as a means for caring for the koji substrate are installed on this rotary culture bed, extending from the center to the outer periphery. Deploy. When the koji making conditions differ between the rotary culture beds in such an arrangement, a partition can be provided between the first stage koji making and the second stage koji making, so that the koji making can be carried out under the respective required conditions. The temperature of the product is controlled by a temperature measurement sensor inserted into the koji substrate, and the temperature is always maintained at the set temperature through ventilation.

As mentioned above, this invention utilizes an insulated koji chamber as it is, and provides a rotating culture bed in a room where the temperature and humidity are maintained at the set conditions by an automatic temperature and humidity adjustment device. Therefore, it has the advantage of significantly reducing installation costs, saving labor in koji making work, and improving quality.

Further, N-9 is a partition (portion shown by imaginary lines) that separates the first-stage koji-making device and the second-stage koji-making device as necessary.

Next, the effects of this invention will be described.

The temperature and humidity of the air in the koji room etc. 1 is measured by a sensor 15'.
The automatic temperature and humidity adjustment device 15 is activated to maintain the set temperature and humidity at all times. The koji substrate that has been pretreated is placed in a rotating culture bed N-1 (in case ventilation is required, the lower part of the rotating culture bed is partitioned and ventilated) as the first stage of koji making. In the filling operation, the conveying screw N-5 is set in advance at the height at which the koji substrate will be deposited, and the driving device is used so that the conveying action of the screw acts in the direction of the center at that position. Rotate. Next, when the rotary culture bed N-1 is rotated and the koji substrate is introduced, the koji substrate reaches the transportation screw N-5 due to the rotation of the rotary culture bed. The koji substrate exceeding the height set by the screw is gradually conveyed to the center cylinder N-4 side by the action of the scraper and the conveying screw N-5,
Rotation of rotating culture bed N-1 and transportation screw N
-5, the koji substrate to be introduced is continuously leveled to the set height, automatically completes the filling, and is constantly adjusted to the set conditions by the room air temperature and humidity adjustment device. The growth of koji mold is promoted under the optimal indoor environment for koji production, and after a predetermined period of time, it is transferred to a culture bed 2 for later stage koji production.

At the time of transfer, the conveying screw 4 is set in advance at a position at a height where the koji substrate is deposited, and at that position, it is rotated by the drive device 7 so that the screw conveying action acts in the direction of the center. Next, the rotating culture bed 2 is rotated, and then the rotating disk bed N-1 of the former koji making bed is driven by the drive device N-6, and the conveying screw N-5 is lowered by the lifting device, and then outside. When the koji substrate is rotated so that conveyance is effected in one direction, the koji substrate is conveyed to the rotating culture bed 2 by the chute N-8. When the koji substrate conveyed to the rotating culture bed 2 reaches the conveyance screw 4, the koji substrate exceeding the height set by the screw is
Due to the action of the scraper 5 and the conveying screw 4, the koji substrate is gradually conveyed to the center cylinder 3 side, and the koji substrate to be introduced is continuously set by the rotation of the rotating culture bed 2 and the rotation of the conveying screw 4. It is leveled to the same height and automatically completes the work of adding the koji substrate. When the filling operation is completed, the conveying screw 4 is retracted above the koji substrate by the lifting device.

The koji production temperature is determined by the product temperature sensor 18 inserted into the koji substrate.
The air blower 16 is activated and regulated according to instructions from the temperature controller 19, and the temperature is always maintained at the set temperature by ventilation of indoor air.

The care work is carried out after a predetermined period of time has elapsed after the koji has been added.The care is performed by rotating the rotary culture bed 2 by the drive device 8 and by rotating the care machine 11 by the rotary drive device 13, while moving the lifting device 12 into the koji substrate. The koji substrate is lowered to a position close to the two sides of the rotating culture bed, and at that position, the koji substrate is sequentially cleaned by the interrelated action of the rotation of the care machine and the rotating culture bed. .

When these care operations are completed, the care machine is retracted above the koji substrate using the lifting device. After the cultivation is completed, when making koji, the rotating culture bed 2 is rotated by the drive device 8, the transport screw 4 is rotated by the drive device 7 so that it is transported outward of the rotary culture bed 2, and the elevating device 17, the koji substrate is lowered to a position close to the floor surface of the rotary culture 2, and by the rotation of the transport screw and the rotary culture bed at that position, the koji substrate is transferred by the rotation of the rotary culture bed 2 and the rotation of the transport screw 4. , and is automatically carried out of the rotating culture bed and transported to the target position by arbitrary wheel transport means.

In such work, if the koji making conditions for the first-stage koji and the second-stage koji are different, a partition N-9 (shown with imaginary lines) is installed between the two rotating culture beds, and the koji is made under the required conditions. can be done. Further, depending on the purpose of koji making, a single rotating culture bed may be arranged so that the first stage koji making and the second stage koji making operations can be completed on the same rotating culture bed.

As mentioned above, this invention is used in the brewing industry or the enzyme industry to constantly adjust the temperature and humidity of the air inside an insulated koji room to set conditions using an automatic temperature and humidity adjustment device, A simple automatic koji making equipment that uses a koji chamber, etc., which is equipped with a rotating culture bed equipped with a screw for transportation and a care device, and is aimed at saving labor, improving quality, and reducing equipment costs for making koji. It is.
