Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a novel structure aimed at complete sealing in a rotating disk type koji making device.

<Conventional technology> A care machine or a loading/unloading machine in a rotating disk type koji making device
In order to make it possible to raise and lower the work equipment, which is the discharge screw conveyor, in a sealed state,
An elongated hole with a stroke length that allows the shaft of the care machine and loading/discharging screw conveyor to move was provided in the airtight wall plate provided on the outer periphery of the rotating disk floor, and the elongated hole was covered with a shielding plate that moved along with the shaft. .

<Problems to be solved by the invention> With such a structure, complete sealing was difficult and the sealing was inevitably insufficient.
Therefore, there were cases in which high-quality koji products could not be obtained due to the contamination of outside air.

<Means for Solving the Problems> In order to solve the above problems, the present invention has the following structure. That is,
The elevating device 5 of the care machine 3 as a working machine installed on the rotary disc floor 2 in the koji making room 1 is isolated from the outside air with a sealing structure similar to the outer wall 6 of the koji making room 1, and the side wall of the disc floor 2 is closed. The space between the sealed installation part 7 and the koji making chamber 1 is covered with a shielding plate that moves together with the shaft through the shaft through hole of the side wall 4 of the disc floor. The lifting screw 8 protruding from the outer wall 6 of the sealed installation part 7 is connected to the lifting motor 9 outside
It was connected to

<Function> With such a structure, the lifting device 5, which was conventionally located outside the wall, can be sealed with a wall surface similar to the outside wall 6 of the koji making chamber of the device outside the side wall 4 of the rotary disk bed 2. It is possible to eliminate incomplete sealing,
Since it prevents the introduction of outside air and is isolated from the koji making room 1, it has the effect of preventing the elevating device from being contaminated by koji.

<Examples> Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a sectional view of a main part of the rotary disk type koji making apparatus of the present invention, and FIG. 2 is a side view of the lifting device.

The rotary disk type koji making apparatus is provided with a care machine 3 or a loading/discharging screw conveyor as a working device on a rotating disk bed 2 in a koji making chamber 1. Circulating air whose humidity and temperature have been appropriately controlled is supplied to the koji making room 1 and passes through the koji layer through ventilation holes provided in the disk bed 2. The temperature and humidity of this circulating air is important for making koji and is precisely controlled. Therefore, mixing of outside air must be avoided.

In the present invention, as shown in the figure, the lifting device 5 is installed in a sealed installation part 7 integrally with the koji making chamber 1 and covered with an outer wall 6 in a sealed state. This situation can be clearly seen in Figure 1. That is, between the sealed installation part 7 and the koji making room 1, the shaft through hole in the side wall 4 of the disk bed is covered with a shielding plate that moves with the shaft, which is a conventional simple sealing structure to prevent the koji from getting wet from the side wall. There is. Here, a bellows 11 that reaches the top of the side wall 4 of the disc floor 2 is provided as a shielding plate, but this only prevents the koji on the disc floor from scattering over the side wall 4 and into the lifting device 5, making it completely airtight. There is no need for this. In order to make the koji making chamber 1 completely sealed from the outside air, the present invention has the following features:
A sealed installation part 7 of the lifting device 5 is provided in a protruding manner with a sealing structure similar to the outer wall 6 of the koji making chamber 1. This sealed installation part 7 is provided with a lifting screw 8 in the vertical direction, the upper end of which is connected to a lifting gear box 10 connected to a lifting motor 9. The lifting screw 8 is screwed into a female threaded portion 22 provided on the lifting mounting base 21 that is integrated with the rotating gear box of the care machine 3, and depending on the direction of rotation of the lifting screw 8, the care machine 3 ( or loading/discharging screw conveyor) moves up and down. By installing the elevating device 5 in the koji making chamber 1 in this way, the difficult disk floor 2
There is no longer a need for a sealed structure.

As shown in FIG. 2, the rotational power of the care machine 3 and the like is transmitted from a care machine rotation motor 23 via a bevel gear to a care machine transmission shaft 24 with a key groove inside the lower lifting mounting base 21. It is transmitted to the shaft of the care machine 3 through the gearbox located in the . These lifting devices 5
In the example shown, the sealed installation part 7 is the lower mounting base 2.
Although only one part is provided, the entire part including the upper motor part may be built-in in some cases.

<Effects of the invention> By adopting the structure described in detail above, the invention eliminates the contamination of outside air, thereby preventing the invasion of various bacteria, and improving the quality of koji products. It was. Furthermore, there is no need for a complicated sealing structure at the edge of the rotating disc floor, making it possible to simplify the apparatus.
