JPS5820157Y2 - Cutting blade structure for maintenance of rotary automatic koji making equipment - Google Patents

Description

[Detailed explanation of the invention] This invention incorporates the rotation of the culture bed of the aerated rotary automatic koji making device, and the rotation of the koji extraction work section and the maintenance work section. The present invention proposes a device that remotely improves the quality of koji by allowing the maintenance work to be performed completely and rationally.

Next, an embodiment of the device of this invention shown in the drawings will be described.

FIG. 1 is a diagram showing a rotary automatic koji making device that adopts the cleaning cutting blade structure of this invention, in which 1 is a rotary disk that can be ventilated, and 2 is a rotary disk provided on the outer periphery of the rotary disk 1. The guide plate 3 is a koji substrate deposited on the rotary disk 1 within the space defined by the guide plate 2 and the rotary disk 1.

drive of the care machine 5, 6 driven by the drive shaft 4';
is a lifting device for the care machine 5, and 7 is a bevel gear mechanism that transmits the rotation of the drive shaft 4' to the care machine main body shaft 8, which is bolted to a support plate 8' attached to the care machine main body shaft 8. A large number of cutting blades 10 are attached to each other through arms 9 that are connected with each other in different phases.

These cutting blades 10 can be inclined with respect to the rotating direction of the shaft 80 so that they can cut into the koji substrate 3, respectively. That's what I do.

In this invention, a spatula-shaped cutting edge 11 made of rubber or other elastic material is attached to the tip of the cutting body 10 with a fastener such as a bolt or screw, and is attached to the rotating disk 1 during cleaning. This allows the tips of the cutting blades to make complete contact and rotate.

When the above configuration is clicked, the care machine main shaft 8 is raised and lowered by the lifting device 6, and the koji substrate 30 is taken care of by the care machine 5.

More specifically, rotation is applied to the cutting blade 10 of the care machine 5 from the drive device 4 via the transmission systems 4' and 7, and the care machine 5 is lowered into the koji substrate 3 by operating the lifting device 6. let

This care machine 5 is lowered at 1 into contact with the rotary disk 1 while cutting the koji substrate 3 by the action of the cutting blade 100 and taking care of the crumbling.

In this case, the rotary disk 1 continues to rotate, and if both the cutting blade 10 of the care machine 5, which is also rotating, and the rotary disk 1 are made of a rigid body, the rigid body Vibrations caused by frictional contact between the blades may cause damage to the cutting blade 10 and the like.

In the past, in order to avoid this risk of damage, it was necessary to set the cleaning device with the lowering limit at a position where the cleaning cutting blade did not come into contact with the rotating disk. An unformed L-koji substrate layer remains, which may result in poor heat removal in the koji produced after the maintenance work, resulting in a significant drop in the quality of the product.

In contrast, in this invention, since the cutting edge 11 of the care machine 5 is made of an elastic material, there is no need to avoid frictional contact of the cutting edge 11 with the rotating disk 1. The koji substrate 3 deposited on the koji substrate 3 can be completely cleaned by lowering the treating machine 5, and by eliminating any residue that has been left untreated, it is possible to improve quality through complete cleaning.
