Description

[Detailed explanation of the invention] This invention was developed until the second cleaning period in the koji making process.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to embodiment drawings, regarding a koji making apparatus that can supply saturated atomized air to a koji making chamber and produce homogeneous koji.

In the figure, reference numeral 1 is the koji making room, into which air from the outside air intake 2 is fed through an introduction duct 7, an air supply duct 8, a blower 3, and a humidifying chamber 4. Part of the air is released into the atmosphere from the exhaust duct 5, and the other part passes through the return duct 6 and joins with the outside air.
After passing through the blower 3 and the humidifying chamber 4, it is sent to the koji making chamber 1 again.

In the humidifying chamber 4, two-fluid nozzles 9a and 9b that eject water together with air are sequentially arranged in the air flow direction. Compressed air is supplied from the branch water supply pipes 11a and llb of the water supply pipe 11, and compressed air from the compressor 12 is sent from the branch air supply pipes 13a and 13b of the air supply pipe 13, so that each nozzle spouts water together with air. .

Further, in the humidifying chamber 4, a mesh damper 31 in the form of a net is provided so as to be openable and closable following the two-fluid nozzle, and an eliminator 16 is also provided on the downstream side of the mesh damper 31.

There are various opening/closing mechanisms for the mesh damper 31, and any mechanism may be adopted. For example, as shown in FIG. 2, individual mesh dampers 31a, 31b, and
...Each rotating shaft 32 at 32 at 31n
b...32n bell crank shaft portions 33a, 33
b...33n are engaged with the holes 35at35b...35n drilled in one sliding plate 34, and the sliding plate 34 allows, for example, the rotational movement of the swing motor M to move in a straight line. In some cases, the reciprocating movement is performed by a reciprocating mechanism 36, 37 that converts it into motion, in other cases, it is performed by a gear mechanism, etc., and the operation of the sliding plate is not by a motor but by manual operation. I love you too.

In addition, an electric valve 2 is installed in the air supply pipe 13 to each nozzle 9a, 9b.
This electric valve 21 is actuated by the output of a humidity regulator 24 into which a signal from a humidity detection sensor 23 installed in a duct 22 between the humidification chamber 4 and the koji making room is input. The amount of compressed air supplied to each nozzle is controlled so that the air to the koji room has a predetermined humidity.
The branch air supply pipes 13a, 13b are provided with manual valves 14a, 14b which allow manual stepwise control during seasons such as winter when the required amount of humidification is small.

Furthermore, the outside air introduction duct 7 is provided with a steam heater 25 for use when drying the koji making room after washing (the steam coil is denoted by 25a), and the air supply duct 8 is equipped with: A heater 26 is provided in the koji making room to heat the air until the koji produces fermentation heat during drying and in the winter.
The steam supply line 27 is equipped with an electric valve 28 that is operated by the output of a temperature regulator 30 to which a signal from a temperature detection sensor 29 provided in the steam supply line 27 is input, and when the temperature regulator 30 is set to a predetermined temperature, The amount of steam supplied to the steam coil 26a is controlled so that the air leaving the humidification chamber has a set temperature.

In addition, in the illustration, 15a and 15b are 14a.

a water supply control valve to the nozzle header that opens and closes together with 14b;
18A1 to 18D indicate air passage opening/closing dampers.

By the way, in the koji making process, it is desirable that supersaturated atomized humidified air is sent to the koji making room until the second step, and saturated humidified air may be supplied after the second step.

In this device, the air guided to the humidifying chamber 4 is passed through a two-fluid nozzle 9.
The sprayed water from a and 9b is used to humidify the air and supply it to the next koji making room.In the process of supplying supersaturated mist humidified air to the koji making room up to the second cleaning, the net-like mesh damper 31 is used as shown in the figure. Leave it open.

Supply of atomized air may not be necessary after the second treatment of koji making, and saturated air may be sufficient.

At this time, the mesh damper 31 is closed, but in the present invention, the mesh damper 31 can be opened and closed freely, so the mesh damper 31 can be closed manually or by driving the motor M of the above-described embodiment. .

In this way, the air humidified by the two-fluid nozzle passes through the next mesh damper 31.
At this time, the supersaturated moisture in the humidified air is absorbed by the mesh damper 3.
1 and gradually become larger droplets, and finally are entrained by air to the next eliminator 16.

The entrained water droplets are growing, have considerable weight, and have a large inertial force, so they are removed by the eliminator without passing through, and the supersaturated water is transferred to the koji making room. It is possible to supply saturated air from which air is removed.

As described above, according to the present invention, atomized supersaturated air can be supplied to the koji making room by the spray water from the nozzle and the eliminator until the second cleaning step in the koji making process, so that all parts and layers of the mash are covered. This allows humidified air to be evenly supplied, thereby preventing temperature differences between the upper and lower layers of the mash, and allowing homogeneous koji production.

In addition, when cooling after the second treatment requires saturated air,
It is only necessary to close the mesh damper 31, and there is no need to remove the mesh damper, making switching easy.
