Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stirring section structure of a hopper for a koji making device.

[0002]

[Prior art]

 JP-A-5-103655 discloses an apparatus and method for obtaining high-quality koji, which is referred to as “breakthrough spirit”, for koji for brewing sake, miso, soy sauce, etc., including sake. In order to make the koji-making environment uniform, a large number of containers containing steamed rice (culture medium) are housed in an environment chamber that controls temperature, humidity, etc. In addition to a circulating device for circulating the liquid up and down, a hopper for mounting is provided for loading the culture medium in a predetermined shape in a predetermined shape in the container and sequentially feeding the culture medium into the circulating device.

The hopper has a funnel-shaped opening into which steamed rice or the like is introduced, and a lower converging portion is used as an outlet, and a stirring shaft for smoothly discharging the culture medium downward while stirring the culture medium is rotationally driven at the outlet. A large number of pin-shaped claws are provided around the agitation shaft so as to radially extend at predetermined pitches.

[0004]

[Problems to be solved by the device]

 However, since the above conventional stirring shaft structure is soft and contains water, when the amount of water in the culture medium is large, only a cavity is formed according to the rotation trajectory of the stirring claw for each pitch, and the culture medium is formed. However, there was a drawback in that it was not discharged.

On the other hand, when the pitch of the nails on the axis line is shortened to project a large number of nails or to project long blade-shaped nails, there are disadvantages such as damage to the culture medium.

[0006]

[Means for Solving the Problems]

 The stirring part of the present invention for solving the above problems includes a funnel-shaped part 7 having an inclined wall (8) which converges downward, and a discharge port 1 formed at the lower end of the funnel-shaped part 7. 1 and a large number of stirring claws 16 projecting on the outer periphery, and a stirring shaft 12 that is inserted into the discharge path of the discharge port 11 and is rotatably supported. In addition, the stirring claws 16 are projected to one side of the peripheral surface of the stirring shaft 12, and the phases of the projecting positions of the adjacent stirring claws 16 with respect to the axis of the stirring shaft are sequentially shifted.

[0007]

[Action]

 The culture medium 5 charged and stored in the funnel-shaped portion 7 of the hopper is rotated by the stirring shaft 12 with the discharge port 11 at the lower end of the hopper 6 being opened, so that the stirring claw 16 on the outer circumference of the shaft causes one side of the shaft. From the one side to the other side, the mixture is continuously agitated toward the discharge port 11 and discharged smoothly and quantitatively.

[0008]

【Example】

 The embodiment shown in the drawings will be described in detail below. The culture substrate depositing device 1 is attached via a hopper frame 4 which is connected to a frame 3 on the side of the circulation device 2 and is provided side by side. The hopper frame 4 is composed of a rectangular parallelepiped frame, and the funnel-shaped portion 7 of the hopper 6 for feeding the culture medium 5 which is rectangular in plan view is inserted from the upper portion of the hopper frame 4 and is supported via the weight sensor 10.

The funnel-shaped portion 7 is provided with an inclined wall 8 which converges downward, is divided into upper and lower parts, and is detachably connected and joined by a clip 9. A plurality of tubular discharge ports 11 each having a rectangular cross section are provided in series. A stirring shaft 12 is inserted in the center of the lower end of the funnel-shaped portion 7 in the front-rear direction, and is rotatably supported by bearings 13 and 14. Around the stirring shaft 12, there is an axial gap. The rod-shaped stirring claws 16 are projected on one side one by one through a fixed pitch (for example, 40 mm), and the adjacent stirring claws 16 are arranged at intervals of, for example, 90 ° around the axis every pitch. It is shifted and projected. Therefore, when the stirring shaft 12 is driven to rotate, the culture medium 5 is dropped and discharged in the converging portion of the funnel-shaped portion 7 from either the front side or the rear side depending on the rotation direction so that the culture medium 5 is successively dug. It Reference numeral 17 denotes a high torque small motor for rotating the stirring shaft, which is attached to the back side of the hopper 6 via a bracket 18 and is connected to the stirring shaft 12 via a coupling 19.

A shutter 21 that opens and closes the opening end and discharges the culture medium 5 in a fixed amount is rotatably supported at the lower opening end of each outlet 11, and the shutter 21 is provided with an arm 22. Is connected to an opening / closing drive device 23 composed of a motor or a relenoid, and the drive device 23 is attached to the lower end of the hopper 6 via a bracket 24. The shutter 21 is opened and closed in cooperation with the stirring shaft 12 and a spiral 26 described below.

Further, one spiral 26 for feeding the culture medium downward is inserted vertically from above at approximately the center position of the discharge port 11 in the front and rear of the hopper 6, and the culture substrate 5 put in the hopper 6 is inserted. Is reliably sent to the discharge port 11 side at the bottom of the hopper. The helix 26 is attached to a beam 27 installed in the upper opening of the hopper 6, and a motor 28 for rotating the helix 26 is attached to the beam 27.

A right end of a conveyor 29 leading to a lower part of the circulation device 2 is inserted into a lower part of the hopper frame 3, and a koji lid 31 which is a container made of a rectangular wooden box is placed on the conveyor 29. Then, the mechanism is carried in so as to be positioned below the hopper discharge port 11, and after the culture substrate 5 is loaded, it is conveyed to the circulation device 2 side.

The container 31 has a rectangular shape in the front-rear direction, and is divided into front and rear parts by a partition plate 32 at the center thereof, and the culture medium 5 is dropped and discharged from the two discharge ports 11 and 11 in the front and rear partition parts. , Each is arranged in a mountain shape with an initial shape. This mountain-shaped arrangement is realized by discharging the culture medium 5 and gradually moving the container 31 slowly by the operation of the conveyor 29.

[Effect of device]

 According to the stirring section structure of the present invention configured as described above, regardless of the amount of water in the culture medium stored in the hopper, even if the stirring shaft is rotated, the rotation locus in the culture medium around the stirring shaft is rotated. The culture medium is smoothly discharged from the discharge port without forming a hollow (bridge phenomenon), and the occurrence of clogging and uneven discharge of the culture medium does not occur.
