Description

[Detailed description of the invention]

[Industrial Application Field J] This invention relates to an air conditioning device for an aeration-type koji-making device, which is used in the brewing and fermentation industries, and is composed of a culture chamber for culturing a koji substrate, the temperature of outside air introduced, and a device for adjusting the temperature. It is something.

[Prior art] In the previous stage of cultivation, the conventional air-conditioning f11 device had low heat generation in the koji substrate and controlled temperature and humidity by circulating conditioned air, but in the latter stage of cultivation, the growth of koji mold caused
The cooling water to control the temperature and moisture content of the 5 items, which generate a lot of heat, exchanges heat with the blown air and performs humidification. For example, in soy sauce making koji, the amount of cooling water used during two heat generation processes was approximately 0.3 nr/h per 120 kg of koji base. When using the ty111I method without wastewater. The cooling refrigerator was used for the koji substrate 120, and 1PS was required. [Alli that invention tries to solve! As mentioned above, the conventional method required a large amount of cooling water, and was extremely uneconomical as the cooling water was discarded after use. Furthermore, even if a refrigerator is used, a large cooling capacity is required, and a rise in equipment costs, running costs, etc. cannot be avoided. [Means for Solving the Problems J] This invention is aimed at reducing the amount of water used during double-koji koji, equipment costs such as refrigerators, and running costs. Bring in outside air,
A heat exchanger for cooling or heating the introduced outside air and an automatic tamper for controlling the set temperature are provided and connected to the air blower at the inlet of the air conditioning device, and the blowing side of this air blower is equipped with a humidifying Vj position. The present invention proposes an air conditioning device for an aeration-type koji making device, which is characterized by being connected to the culture chamber, and which combines the heat exchanger, automatic damper, blower, and humidifying device, Compared to the conventional method, the amount of cooling water consumed can be reduced to 1,150 ml. Furthermore, when cold water cooled by a refrigerator is supplied to the heat exchanger and outside air is introduced, the capacity of the refrigerator is lower than that of the conventional method.
The present invention aims to provide an air conditioning device for an aeration-type koji making apparatus that can reduce the cost by 2. [Effect] Once the koji substrate has been incorporated into the culture bed, there is no extreme heat generation in the first stage! i11 Conditioned air causes circulation. In order to keep the product temperature constant, the feeder provides slight ventilation. In the first stage of 12w1, as the growth of the koji substrate progresses and heat generation becomes vigorous, J! ! Based on the correlation between the temperature sensor and the computer 9 (which includes a general temperature and humidity control device), the number of rotations of the blower is increased by the inverter in an attempt to bring it closer to the set air temperature. Even if the maximum rotation speed is reached, if the temperature of the air blown to the koji substrate does not drop to the set air temperature, the automatic damper for introducing outside air is gradually opened to bring it closer to the set temperature a. The automatic damper opens, and at the same time the fine mist generator operates, heating the air and bringing the air to saturation. When the set air temperature is reached, the automatic damper will stop at that opening position, and the J! As the heat progresses, the opening of the automatic damper advances, and when the temperature of the air blown to the koji substrate does not reach the set air temperature even when the opening reaches 100%, cold water or water is automatically supplied to the heat exchanger and the set temperature is reached. It operates to match the wind temperature. Therefore, the curve of air blowing temperature from the time of adding the koji to the time of releasing the koji is input into the computer, and based on the detection by the air temperature sensor, the heat generation of the 11 substrates (σ) is adjusted according to the progress of the air blower, automatic damper, fine mist generator, and heat exchanger. are operated sequentially so as to match the sending IIL temperature setting curve. In addition, in the later stages of koji making, as the heat generation of the koji substrate gradually decreases, the operations of the heat exchanger, microlln generator, automatic damper, and feeding JIL machine are closed or reduced in the order of the above 6. When it is incorporated at a low temperature and self-heating is slow, hot water can be supplied to the heat exchanger to warm the introduced outside air and raise the temperature of the blast, thereby raising the temperature of the koji substrate. v4J Next, embodiments of the present invention will be described with reference to the accompanying drawings. The culture chamber 1 is constructed with a heat insulator, and the koji substrate is deposited on the tg culture bed 2, and is divided into an upper chamber 4 and a lower chamber 5. Since the koji substrate does not generate extreme heat in the previous stage, the blower 12 blows the duct 6.11. Louver 14° Humidification chamber 13
, Elminator 15. A gentle breeze is aerated through the duct 16° to the koji substrate 2 through the lower chamber 5, which is sucked from the upper chamber 4 and follows the @ ring path. As the koji grows over time and begins to generate heat, the air temperature is detected by the air temperature sensor 17 and the rotation speed is increased by the air blower 12 or inverter control according to instructions from the computer, following the above-mentioned wi ring path. Even when the rotational speed reaches the maximum, and when the air temperature does not drop below a set value, an automatic tamper 7 for introducing outside air gradually opens to introduce outside air from an outside air intake port 9. Furthermore, when the automatic damper 7 receives an indication that the automatic damper 7 is open, when outside air is introduced, the humidity of the outside air is low. Start heating. The introduced air is passed through a louver 14, humidified by a fine mist generator, and then replenished with the humidity necessary for culture. Excess water droplets are removed by an eluminator 15 and supplied to the culture chamber 1 via a duct 16. By the above operation, the amount of outside air introduced during one operation,
If the set air temperature discharged to the outside from the duct 8 is the same as the air temperature detected by the air temperature sensor 17, the automatic damper 7
The opening will stop at that position. As the heat generation of the koji substrate becomes more intense and the air temperature rises, the outside air introduction automatic damper 7 opens further and the opening degree increases to 100.
%, if the blowing temperature still does not drop below the set air temperature, the cooled water is cooled by the refrigerator 18 to the heat exchanger lO, and the cold water stored in the tank 20 is transferred to the pump 21. Water is supplied by the operation of the electromagnetic material 22, and the introduced outside air is cooled to a set wind temperature. Automatic damper 7, duct 11. Send @ machine 12. Louver 14.
Fine mist generating nozzle 31. Elmy, - evening 15, duct 1
6 and then aerate the koji substrate in the lower chamber 5. The air that has exchanged heat with the koji substrate is transferred to a duct 6, an automatic damper 7,
7. The koji substrate is discharged to the outside through duct 8. In addition, in the later stages of koji making, the koji substrate gradually decreases by one layer due to heat generation. Each of the above devices sequentially stops the water supply to the heat exchanger IO, closes the own V3 damper 7, and WaMA fog generation nostle 31. Pump 28, solenoid valve 2
By stopping at 9.30, humidification is stopped and the rotational speed of the blower 12 is gradually reduced. The koji substrate is loaded at a low temperature (b). When self-heating is slow, it is detected by the product temperature sensor 33, and hot water heated in the water tank 25 is transferred to the heat exchanger (a) by the pump 24. Hot water is supplied by the operation of electromagnetic ti23,
The temperature of the koji substrate 2 can also be raised by adjusting the temperature of the outside air introduced. When the koji production is completed and the culture chamber is washed, steam is supplied to the drying device 32 in order to quickly dry the culture chamber. Hot air is supplied to the culture room by operating a blower. It also has drying equipment. [Effects of the Invention] As mentioned above, this invention does not directly remove heat from the return air from the koji substrate using water or a refrigerator as a means of cooling the heat generated by the koji substrate, as in the conventional method. Introduced outside air with low enthalpy is transferred to the koji matrix using water or a refrigerator using a heat exchanger.
Since the temperature is automatically adjusted and air is blown at the appropriate temperature, it is possible to obtain koji with high potency, and it is a useful and useful device that can significantly reduce the amount of water used during koji making and the refrigeration function.
