Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a method for incorporating a koji substrate into a rotary disk type koji making device.

[Prior art]

The conventional method for loading the koji substrate into the circular culture bed of the rotary disk type koji making device is to move the loading apparatus in inverse proportion to the peripheral velocity of the circular culture bed (Act No. Sho 53-42640). ,
It is possible to exemplify a method (Act No. 57-18960) of sequentially moving the filling device from the inner circumference to the outer circumference or the opposite direction in accordance with a signal from the detection unit of the height of koji substrate filling while rotating the circular culture bed. .

[Problems to be Solved by the Invention]

In the above-mentioned method, it was difficult to control that the starting point and the end point had no burrs and that the peripheral velocity of the circular culture bed was inversely proportional. Also, as shown in Fig. 3, even though the structure of is moved sequentially, the loading device that has moved in one direction on the circular culture bed stops moving until it finishes the loading that should move in the same direction next time. Since it is piled up on the same circumference there, the unevenness of the veins on the piled surface is remarkable, and the surface must be smoothed, so a separate leveling plate is required, and it is troublesome to level it. There was a difficulty.

[Means for solving problems]

Therefore, in the present invention, a rotating circular culture bed (1)
Is virtually divided into a plurality of raised areas having substantially equal floor areas by concentric circles, and the koji substrate supply amount per unit time of the koji substrate is constant while the circular culture bed (1) makes one rotation. The koji substrate supply port (4) of the mashing device is reciprocated a plurality of times between the two poles in the radial direction of one mashing region, and the koji substrate supply port (4) is rotated every one rotation of the circular culture bed (1). ) From which the area to be loaded with the koji substrate is transferred from one of the loading areas to the other, and the koji substrate is loaded into each of the loading areas in substantially equal volumes. The koji substrate was incorporated into the rotating disk type koji making device. Here, it is usually 1 to 4 to include the koji substrate.
Since it takes time, the variation in the supply amount of the koji substrate per unit time has only to be constant to the extent that there is substantially no difference. For example, the unit time is about 1 to 10 minutes. Also,
The volume substantially equal to each other in each of the filling regions means that when the same filling height is formed on the circular culture bed (1), the total circulated filling volumes are equal, and therefore, are inside. The crossing distance from the end to the end in the radial direction for the divided embedding area,
That is, the moving distance of the koji substrate supply port (4) is long. The multiple reciprocating movements from end to end in the radial direction determine the moving speed and the reciprocating distance depending on the rotation speed of the circular culture bed and the supply amount of the koji substrate, but in short, zigzag stripes are formed on the upper surface of the incorporated koji. Set the condition that there is little groove or swelling on the groove or the boundary of each divided embedding area.

[Action]

According to such a method, the koji substrate supply port (4) reciprocates in each divided swelling region to perform swelling a plurality of times, so that the surface does not form a pulse and is a flat surface. There is. Therefore, there is no need to provide a separate leveling plate,
You can save the trouble of breaking in.

【Example】

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a plan view of a rotary disk type koji making apparatus embodying the present invention, and FIG. 2 is an enlarged vertical cross-sectional view showing a divided state of a raised floor. FIG. 3 is a partial vertical cross-sectional view showing a built-up state in the conventional method. In the rotary disk type koji making device shown here, the koji substrate (3) is loaded into the circular culture bed (1) by the conveyor of the loading device (2). The filling can be performed from the center of the circular culture bed (1) toward the outer periphery, and vice versa. This embedding has conventionally been performed by retreating or advancing the koji substrate supply port (4) on the rotating circular culture bed (1) in one direction by the above method or. Unlike the conventional method as described above, the filling method of the present invention moves the koji substrate supply port (4) back and forth a plurality of times between both ends in the radial direction of one of the filling regions to form the circular culture bed (1). The region to be charged with the koji substrate from the koji substrate supply port (4) every one rotation is transferred from one of the kneading regions to the other, and the koji substrate is placed in each of the kneading regions. It was designed so that the volumes would be approximately equal to each other. An example thereof will be described with reference to FIG. 16 in this example
A circular culture bed (1) of m is divided into 3 concentric circles. The diameter of the inner cylinder rotatably supporting the circular culture bed (1) is 2.8 m. The koji substrate (3) is supplied to each of the divided embedding regions in upper and lower two stages. Actually, the dividing line (5) does not exist on the circular culture bed (1), but it is shown for explanatory purposes. The koji substrate supply port (4) first supplies the koji substrate (3) to the divided embedding region (Ia) of the circular culture bed (1). In this feeding method, the koji substrate feed port (4) reciprocates a plurality of times (16 times in one rotation of the circular culture bed in this example) within the divided embedding area up to a moving distance of 3.4 m from the inner cylinder side. By doing. At this time, the koji substrate is fed from the koji substrate supply port (4) at substantially the same volume of the koji substrate per unit time, and the circular culture bed (1) is rotated at a constant speed so as to rotate once in 20 minutes as in the conventional method. It is rotating at. The circular culture bed (1) is rotated almost once when the height of the piled up becomes constant by the sensor detection, or when the predetermined rotation time of the circular culture bed has passed, and one divided piled area is divided. When the filling amount to fill the unit volume is reached, the koji substrate supply port (4) is moved to the divided filling region (IIa). In this example, the divided embedding area (IIa) is the koji substrate supply port (4).
The moving distance of the koji substrate is set to 1.8 m, and the koji substrate supply port (4) reciprocates a plurality of times (31 times while the circular culture bed makes one rotation in this example) during that time, and the koji substrate is supplied in the same manner as described above. To supply. Repeating this operation, when the supply is completed up to the divided build-up area (IIIa) (movement distance of the koji substrate supply port (4) is 1.4 m, the number of reciprocating movements during one rotation of the circular culture bed is 40), Further, the koji substrate (3) is supplied onto the formed embossing surface. For that purpose, the koji substrate supply port (4) is moved to the divided embedding region (Ia) to move from the divided embedding region (Ib) to the divided embedding region (III).
The koji substrate was similarly supplied until b). There were 6 areas for divided filling, and the round culture bed was rotated once in 20 minutes, so that the feeding time was about 2 hours. Since the surface of the koji substrate thus supplied does not have remarkable unevenness or a portion where there is no build-up at the start point and the end point of build-up as in the conventional case, it is not necessary to make it flat with a screw or the like. When the supply of the raw material for feeding is interrupted for some reason, it is convenient to detect it by a sensor and stop the rotation of the circular culture bed.

【The invention's effect】

According to the method of the present invention as described in detail above, the koji substrate can be uniformly added, so that a uniform and good quality product can be obtained. The veins on the surface of the koji substrate have disappeared, and the work required for the leveling work has been saved, and it is no longer necessary to provide a separate leveling plate.
