Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a koji making device for general enzyme industry and brewing industry.

[0002]

[Prior art]

 Conventionally, the koji-making means of the multi-stage koji making device has been so arranged that the adjusted air is sequentially passed through the koji substrate accumulated on the culture bed of each stage, so that the upstream side where the adjusted air is charged has a temperature. The humidity was low, and the humidity was high on the downstream side, making it impossible to achieve the desired homogeneous koji making.

[0003]

[Problems to be solved by the device]

 In the above-mentioned koji making device, when the ventilation is stopped under the set conditions, the air in the upper chamber of the culture bed is stopped in a saturated state, so that the set koji making environment cannot be cultivated, and the multi-stage control at the time of control Since the conditioned air sequentially passes through the koji substrate to the culture bed that is configured as a unit, the temperature and humidity are low on the upstream side of the charging and high on the downstream side, which is always the purpose with no difference. I couldn't make uniform koji.

[0004]

[Means for Solving the Problems]

 In this invention, an aerable culture bed is vertically configured in multiple stages in a room constituted by a heat insulating wall, and the room air on each culture bed is set by temperature and humidity adjusting means. By adjusting so that the temperature and humidity are kept constant, an optimum indoor environment for koji making is created, and arbitrary koji making is performed under that environment.

In order to carry out control by ventilating the conditioned air in the chamber on each culture bed to the koji substrate deposition layer, the inlet and outlet of the regulated air are provided to each culture chamber on the floor of the culture bed via a blower. And place it under the floor and set a time lag according to the koji manufacturing conditions set for the koji substrate for each culture bed unit by operating the instrument, and let the adjusted air be inhaled and blown to ventilate the koji substrate. Control. Therefore, the conditions of temperature and humidity of the air ventilated in each stage of koji substrate are always the same, and the desired uniform koji making can be performed.

[0006]

[Embodiment of device]

 FIG. 1 is a vertical cross-sectional view of the apparatus. In FIG. 1, 1 is a koji making chamber composed of a heat insulating wall, in which the air permeable culture beds 2, 2 ', 2 "are layered in multiple layers. In addition, the suction ducts 3, 3 ', 3 ", the circulation fan 4, the temperature / humidity adjusting means 5, the heater 6, the suction ducts 7, 7', 7 are used as a supply circuit for adjusting air. Is provided, and suction ports A, B, C and aeration ports a, b, c for ventilating the koji substrate during product temperature control are provided for each culture bed, and the suction ducts 3, 3 ', 3 are provided. "And the suction ducts 7, 7 ', 7" are provided with automatic opening / closing devices provided with the shutters 3A, 3A', 3A "and 7A, 7A ', 7A" to enable the time difference operation.

Reference numeral 8 denotes a blower for ventilating, for example, a blower, which is provided with a temperature / humidity sensor 9 and a product temperature sensor 10 as control means for each stage divided into upper and lower parts of the chamber 1. To be In addition, a baffle floor 11 is provided at the top of the chamber 1.

In the above-mentioned configuration, the pre-treatment-completed and inoculated koji substrate is once deposited on the bake bed 11. After completion of the skeining process in the first half of the koji making, the koji substrate is put into the culture beds 2, 2 ', 2 "provided in layers in multiple stages, and the indoor air is circulated in the circulation ducts 3, 3', 3", blowers. 4, the temperature and humidity adjusting means 5, the heater 6, the suction duct 7, 7 ', 7 "by the operation of the path, the culture chamber 2,2', 2" upper chamber temperature and humidity of each stage Always adjust to the setting conditions to create the optimum environment for koji making. Further, when the temperature of the product becomes higher than the set value due to the progress of the koji mold breeding, the product temperature sensor 10 senses it, the blower 8 is activated, and the cultivation floors 2, 2 ', 2 "are sequentially adjusted with a time difference. The indoor air is ventilated and controlled by the koji substrate.

[0009]

[Effect of device]

 According to this invention, in each culture bed, the air in the room above each culture bed is adjusted to the set constant temperature and humidity, and the optimum indoor environment for koji making is created. In the koji making, the product control is controlled by setting a time lag for each culture bed unit, so the temperature and humidity conditions of the air ventilated in each stage of the koji substrate are the same. It is possible to complete uniform koji making.

Further, the present invention is useful and useful in addition to the fixed culture bed as shown in the above-mentioned embodiment, and can be applied to other moving type culture beds such as a belt type culture bed and a rotary culture bed. .
