[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention mainly relates to an automatic koji making device used for solid culture in the enzyme industry and the brewing industry.

[0002]

[Prior art]

 As the koji making process progresses, the koji deposition layer shrinks and cracks occur in the koji deposition layer, and there is a gap between the jacket plate and the koji deposition layer provided on the outer periphery of the rotary disc that is the cultivation bed. May occur. In this state, the conditioning air ventilated in the koji deposition layer short-passes through cracks and gaps, making it impossible to control the temperature of the koji deposition layer. Therefore, by lowering the care device to the middle position of the koji deposition layer and caring for the upper part of the koji deposition layer, cracks and gaps were eliminated and uniform ventilation was maintained.

[0003]

[Problems to be solved by the device]

 Since a phenomenon in which a gap is created between the jacket plate and the koji piled layer is high in frequency, only the method of maintaining the upper part of the koji piled layer with a maintenance device causes excessive agitation of the koji piled layer, resulting in deterioration of the koji quality. Invite. An object of this invention is to provide a koji outer peripheral disintegrating device of a disk-type automatic koji making device, which prevents only the occurrence of a gap between a high-frequency jacket plate and a koji deposition layer and does not deteriorate the koji quality. Is.

[0004]

[Means for Solving the Problems]

 According to claim 1 of the present invention, a jacket plate is provided on the outer peripheral portion of the rotary disc that is a culture bed, and the rotary disc rotates while sliding on the jacket plate. The koji substrate is placed in a cylindrical space formed by the jacket plate and the rotating disk. Protrusions for koji collapse are provided on the jacket plate. The protrusion may be directly fixed to the jacket plate or may be removable. As the koji deposition layer rotates with the disk, the protrusions on the jacket plate collapse only the outer periphery of the koji deposition layer, filling the gap between the jacket plate and the koji deposition layer, and adjusting air short path. Prevent.

According to a second aspect of the present invention, a single or a plurality of protrusions for koji collapse are provided in the vertical direction of the jacket plate. When the koji deposition layer has a constant height, it is effective to provide a single projection at a predetermined height. When the height of the koji deposition layer fluctuates, a plurality of protrusions are provided so as to cope with the variation of the height of the deposition layer and exert an effect. It is not necessary to provide the protrusions in a straight line in the vertical direction of the jacket plate, but adjust the position according to the application. The number of protrusions may be adjusted depending on the type of koji substrate.

According to a third aspect of the present invention, one or more protrusions for collapsing koji are provided in the horizontal direction of the jacket plate. When the gap between the jacket plate and the koji deposition layer does not occur frequently, it is effective to provide a single protrusion at a predetermined position. When the gap between the jacket plate and the koji pile layer is frequently generated, it is effective to provide multiple protrusions. That is, when the protrusions are provided at positions where the jacket plate is divided into four equal parts, the entire outer peripheral portion of the koji deposition layer can be collapsed only by rotating the koji deposition layer by 90 °. The number of protrusions may be adjusted depending on the type of koji substrate.

In carrying out the apparatus according to any one of claims 1 to 3, by controlling the rotation start timing, time interval, rotation speed, and rotation angle of the rotary disk, various koji substrates having different koji making conditions can be used. You can respond. That is, the rotation of the disk is controlled by the drive device of the rotary disk, and the outer periphery of the koji deposition layer is collapsed. Since the time from the start of the koji making process until the gap between the jacket plate and the koji deposition layer varies depending on the type of koji substrate, the disc can be rotated from any time. Since the frequency of the gap between the jacket plate and the koji deposition layer varies depending on the type of koji substrate, the disk can be rotated at any time interval. Since the degree of collapse of the koji deposition layer varies depending on the type of koji substrate, the disk can be rotated at any rotation speed. Furthermore, since the number of protrusions in the horizontal direction and the degree of collapse of the koji deposition layer are different, the disc can be rotated at any rotation angle.

[Embodiment of device]

 Embodiments of the present invention will be described below according to the embodiments shown in the drawings. FIG. 1 is a vertical cross-sectional view of an embodiment of an automatic koji making device adopting a device for collapsing the koji outer periphery of a disk type automatic koji making device according to the present invention. FIG. 2 is a cross-sectional view of the koji outer peripheral part disintegrating device of the disk type automatic koji making device, and FIG. 3 is an enlarged vertical cross-sectional view of the koji outer peripheral part disintegrating device. The disc 1, which is a culture bed, is rotated by a drive device 3 about a rotation shaft 2. The disc 1 slides and rotates with respect to the jacket plate 5 fixed to the koji-making inner wall 4, and prevents the koji substrate from dropping below the disc.

1 to 3, the jacket plate 5 is provided with four protrusions 6 at the four horizontal positions, that is, two protrusions at the top and bottom. In such a state where the protrusions 6 are installed, the outer peripheral portion of the koji deposition layer 7 can be completely collapsed by rotating the disc 1 90 °.

The shape of the protrusion 6 may be a round bar shape, a plate shape, or the like capable of collapsing the koji deposition layer, but a round bar shape or the like having no corners is preferable from the viewpoint of sanitary properties. The protrusion 6 may be fixed to the jacket plate 5 directly by welding, but as shown in FIG. 3, a fixing metal member 8 may be provided on the back surface of the jacket plate 5 so that the protrusion 6 can be moved and removed. Further, the structure of the fixing member 8 can be moved in the vertical direction so that the height of the protrusion 6 can be adjusted, and as a means for vertically moving the fixing member 8, a driving device such as an air cylinder may be provided for control.

The rotation of the disc 1 is controlled according to the type and the amount of the koji substrate used. Control items such as the rotation start timing, time interval, rotation speed, and rotation angle of the rotating disk are set in a control device (not shown), and the outer peripheral portion of the koji deposition layer is efficiently collapsed.

[0012]

[Effects of the Invention] The apparatus for collapsing the outer peripheral portion of the koji deposition layer of the disk-type automatic koji making device of the present invention has the above-described mechanism, so that the gap in the outer periphery of the koji deposition layer can be collapsed by a simple mechanism. Can be buried. Since the koji is also partially collapsed, it is possible to prevent the deterioration of quality. Even if the usage amount of the koji substrate changes, it can be dealt with by providing a plurality of protrusions in the vertical direction or by making it movable up and down. In addition, since the shape of the protrusion is small, it does not resist the rotation of the disk, so it can be used with normal driving power, and it can be easily installed on the existing disk-type automatic koji making device. In particular, this invention is further significant in that various disk rotation conditions can be set in accordance with different raw material koji substrates.
