Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary type koji making device, and its object is to provide a very labor-saving koji making device.

'Conventionally, a rotary table is installed in a cylindrical koji-making chamber, and koji-making raw materials are supplied onto this table, and while the table rotates, it is made into koji and taken out. Various types of rotary koji-making equipment have been reported. There is.

This rotary koji making equipment is easy to manage and has long been attracting attention because of its ability to make koji continuously, but when it comes to actually designing the equipment, it is necessary to evenly distribute the raw materials inside the rotating sealed chamber. There are problems with the equipment for putting in the koji and the equipment for taking it out after making the koji, and no satisfactory equipment has yet been developed.

□ Conventionally, when loading raw materials into this type of equipment, the raw materials were loaded in a mountain shape on a table and leveled with a ■-shaped leveling plate (Utility Model Publication No. 35-3291), or a conveyor belt was placed on a rotary table. (Japanese Patent Publication No. 47-43077), but the former method is not expected to have a sufficient leveling effect. However, the latter has the disadvantage that the apparatus is too complicated, and if the koji making chamber is circular, it is difficult to install the conveyor indoors.

Also, methods are known in which the koji after koji production is carried out with a screw or discharged by suction (Japanese Patent Application Laid-open No. 118899/1989), but in either case, the device is provided separately from the raw material supply device.

Providing such a large number of devices within the device not only complicates the device, but also makes sterilization and management of the device difficult, which is not desirable.

The present invention was made to solve these drawbacks.
A rotating koji-making box is placed inside a circular sealed koji-making chamber, and a hollow tube that penetrates the wall of the koji-making chamber and reciprocates in a direction perpendicular to the direction of rotation is installed.The air flowing through this hollow tube is used to produce raw materials. The raw material is fed into a koji box, and with the rotation of the stirring device, the surface of the raw material is leveled.
In the case of rice, it is steamed, and after completion of the steaming, it is crushed, seed koji is inoculated, and koji is made.After the koji is made, the koji is sucked and discharged while the hollow tube is moved back and forth.

The reciprocating movement of the hollow tube is performed by rotating a cam screw installed outside the koji making chamber, and the reciprocating speed is increased near the center of the koji making box and slowed down in the farthest areas. A fixed tube is inscribed inside the hollow tube that supplies and reciprocates.
This problem was solved by connecting an air supply fan to one end of this fixed tube, providing a seed koji supply port, a koji raw material input port, and an intake pipe for management, and allowing air to be supplied or taken in.

Furthermore, at least the upper part of the koji making chamber is made of two layers, and the inside of the layer is heated to prevent water droplets from forming on the ceiling and to prevent quality deterioration due to water wetting.

To explain the present invention in detail with reference to the drawings, reference numeral 1 denotes the inner wall of the koji chamber, which has a circular cross section and is enclosed on all four sides to form a closed koji chamber.

2 is the outer wall, and at least the ceiling has a double structure.

A cavity is formed between the outer walls 1 and 2, and warm air is blown into the cavity as necessary to heat it and prevent condensation from forming on the interior walls and ceiling.

An exhaust pipe 3 is provided at the center of the inner wall 1, and a gear 4 is fixed below the exhaust pipe 3 and rotated by a motor 5.

Note that 3' is an exhaust pipe that is connected to the exhaust pipe 3 and whose side extends outside the inner wall 1.

Reference numeral 6 denotes a frame, with the exhaust pipe 3 as its axis, and a number of rods fixed radially thereto.

A koji making box 7 whose bottom part is made of wire mesh 8 is placed on top of the pedestal 6.

Therefore, the koji making box 7 is configured in a circular shape between the exhaust pipe 3 and the inner wall 1 and rotates together with the exhaust pipe 3.

Further, a steam pipe 9 and an air pipe 10 are opened below the inner wall 1, and an inclined partition plate 11 is fixed, and a drain pipe 12 is provided at the inclined end.

Further, a stirrer 13 is provided horizontally above the koji making box 7,
A large number of stirring rods 14 are installed on the circumference thereof.

This stirrer 13 is supported at both ends by support rods 15 that penetrate through the inner and outer walls 1 and 2, and is movable up and down by a bundle 16 fixed to the outside of the inner and outer walls 1 and 2.

Although the stirrer 13 is not shown, it is rotated by power.

In the figure, one is shown, but two or more may be provided.

Next, a hollow tube 17 is inserted through the inner and outer walls 1 and 2 toward the center of the circle, and is slidably supported by a bearing 18 on the inner and outer walls 1 and 2.

Further, the end A of the hollow tube 17 is curved, and the length of the curved part A is such that it can approach the surface of the wire mesh 8.

In the figure, the end A is raised horizontally to show a state where it is not in use.

Further, a fixed tube 19 is slidably inscribed in the hollow tube 17, and this fixed tube 19 is fixed by a support rod 20,
A guide rod 21 of the hollow tube 17 is fixed above the support rod 20 between it and the outer wall 2.

Further, a connecting ring 2 is connected to the end of the hollow tube 17 and is slidable.
2, the fixed tube 19 is inscribed inside the connecting ring 22, the floating plate 23 is fixed on the upper outside, and the hollow tube position support rod 24 is freely movably attached.

A hole 25 is provided in the plate 23 and the guide rod 21 is fitted therein.

A driving protrusion 26 is fixed below the connecting ring 22.

A cam screw 27 is provided below and parallel to the fixed tube 19, and is rotatably supported by the outer wall 2 on one side and the support rod 20 on the other side.
Let them loosely fit.

28 is a reduction gear fixed to the cam screw 27 and driven by a continuously variable transmission 29, which is driven by a motor 30.

The continuously variable transmission 29 has a rope 31 tied to the connecting ring 22.
When the connecting ring 22 moves to the right and the hollow tube 17 retreats, the rotation of the cam screw 27 is slowed down, and when it moves forward, it speeds up.

This is because the koji making raw material passes through the hollow tube 17 and is evenly dispersed in the koji making box 7, as will be described later.
The ratio of the inner circumference to the outer circumference of the cam screw is made proportional to the rotational speed of the cam screw.

Since the cam screw is essentially used for the above purpose, the purpose can be achieved even if the rotational speed is fixed and the pitch of the cam screw is changed by the above means.

The end of the fixed tube 19 is connected to a fan 32 to allow air from an air filter 33 to flow therethrough, and a seed supply device 34 and a raw material supply port 35 are opened in the middle.

A partition plate 36 is preferably provided below the raw material supply port 35,
The air from the fan 32 is compressed downward to convert the pressure energy into velocity energy to facilitate the suction of the raw material falling from the quantitative feeder 37 located above.

At this time, it is preferable to provide a branch pipe to the fixed pipe 19 so that a part of the air flows into the raw material supply port 35.

Reference numeral 41 denotes a rotating rod fixed to the outside of the hollow tube 17, which engages with the hollow tube position support rod 24 to rotationally support the hollow tube 17.

Further, an intake pipe 38 is branched from the middle of the fixed pipe 19 and connected to a cyclone 39, so that suction can be performed by a fan 40.
