Further, in the preheating step, the control device 50 performs humidity control so that the humidity in the storage case 12 is 75%, in addition to the temperature control described above. When the control device 50 detects the lower limit setting humidity where the humidity detected by the humidity sensor 19 is lower than 75%, it is controlled to be humidified by the humidifier 40, and when the detection humidity by the humidity sensor 19 detects the upper limit setting humidity higher than 75%. It is controlled to stop the humidification by the humidifier 40. When the inside of the storage case 12 is humidified by the humidifier 40, the storage time of the storage case 12 is controlled so that water is sprayed intermittently by alternately repeating the spraying time and the waiting time from the spray nozzle 41 of the humidifier 40. ing. By intermittently spraying water from the spray nozzle 41, it is possible to vaporize the sprayed water in the standby time and sufficiently spread the inside of the storage case 12.

There is. In addition, although the standby time prescribed | regulated with one part temperature and partial humidity is shown in FIG. 7, and the standby time prescribed | regulated by other temperature and humidity is abbreviate | omitted, the standby time of the temperature and humidity which are not shown is It has a proportional relationship with the standby time for each temperature shown and the standby time for each humidity. P
When performing humidification by the humidifier 40 based on the detected humidity of the humidity sensor 19 while performing the preheating step, the control device 50 sets a standby time defined by the temperature and humidity in the storage 12 described above. The standby time is derived from the detected temperature of the temperature sensor 18 and the detected humidity of the humidity sensor 19. When the control device 50 detects the lower limit setting humidity in which the humidity detected by the humidity sensor 19 is lower than 75%, the water supply valve 42b is opened for 2 seconds which is a spraying time to mist the water for 2 seconds which is a spraying time from the spray nozzle 41. It controls so that spraying and water supply valve 42b are closed by calculated waiting time, and waiting to spray water is repeatedly performed. When water is sprayed in the form of mist from the spray nozzle 41, the air sent from the inside of the storage 12 to the duct passage 16 by the circulation fan 17 is the water sprayed from the spray nozzle 41 in the vertical duct passage 16a. The vaporized and humidified air is sent again to the storage 12 through the vertical duct passage 16a and the horizontal duct passage 16b as shown by the two-dot chain arrow in FIG. 4 and the inside of the storage 12 is It is humidified by humidified air.

  Two hours after the start of the preheating process, the control device 50 executes a fermentation (hollow) process. In the flop (fermentation) process, the control device 50 controls the temperature of the inside of the storage case 12 to 35 ° C. by controlling the operation of the heater 31 based on the temperature detected by the temperature sensor 18, thereby the humidity sensor By controlling the operation of the humidifier 40 based on the detected humidity of 19, the humidity in the storage 12 is controlled to 85%.

  When the temperature detected by the temperature sensor 18 detects a set lower limit temperature lower than 35 ° C., which is the set temperature of the storage 12, the heater 31 is controlled to operate, and the detected temperature of the temperature sensor 18 is the set temperature of the storage 12 When a set upper limit temperature higher than a certain 35 ° C. is detected, control is performed to stop the operation of the heater 31. When the heater 31 is operated, the air sent from the inside of the storage case 12 to the temperature control space 16 c of the duct passage 16 by the circulation fan 17 is heated by the heater 31. As indicated by the two-dot chain arrow in FIG. 4, the heated air is again sent to the storage 12 through the vertical duct passage 16a and the horizontal duct passage 16b, and the inside of the storage 12 is warmed by the heated air. Be

  Further, the control device 50 controls the humidity in the storage 12 so that the humidity in the storage 12 is 85%, not only in the temperature control described above, but also in the polishing (fermentation) process. When the control device 50 detects the lower limit setting humidity where the humidity detected by the humidity sensor 19 is lower than 85%, it is controlled by the humidifier 40 to be humidified, and when the detection humidity by the humidity sensor 19 detects the upper limit setting humidity higher than 85% It is controlled to stop the humidification by the humidifier 40. When the inside of the storage case 12 is humidified by the humidifier 40, the storage time of the storage case 12 is controlled so that water is sprayed intermittently by alternately repeating the spraying time and the waiting time from the spray nozzle 41 of the humidifier 40. ing. By intermittently spraying water from the spray nozzle 41, it is possible to vaporize the sprayed water in the standby time and sufficiently spread the inside of the storage case 12. Further, in this embodiment, the spraying time from the spraying nozzle 41 is set to 2 seconds, and the standby time of the spraying nozzle 41 is defined by the temperature and humidity in the storage 12 as shown in FIG. There is. In addition, although the standby time prescribed | regulated with one part temperature and partial humidity is shown in FIG. 7, and the standby time prescribed | regulated by other temperature and humidity is abbreviate | omitted, the standby time of the temperature and humidity which are not shown is It has a proportional relationship with the standby time for each temperature shown and the standby time for each humidity.

  The control device 50 also prescribes the temperature and humidity in the storage 12 described above when humidifying with the humidifier 40 based on the detected humidity of the humidity sensor 19 when performing the Flo (fermentation) process. The standby time is derived from the detected temperature of the temperature sensor 18 and the detected humidity of the humidity sensor 19 using the determined standby time. When the control device 50 detects the lower limit setting humidity in which the humidity detected by the humidity sensor 19 is lower than 85%, the water supply valve 42b is opened for 2 seconds which is the spraying time, and water for 2 seconds which is the spraying time is misted from the spray nozzle 41. It controls so that spraying and water supply valve 42b are closed by calculated waiting time, and waiting to spray water is repeatedly performed. When water is sprayed in the form of mist from the spray nozzle 41, the air sent from the inside of the storage 12 to the duct passage 16 by the circulation fan 17 is the water sprayed from the spray nozzle 41 in the vertical duct passage 16a. The vaporized and humidified air is sent again to the storage 12 through the vertical duct passage 16a and the horizontal duct passage 16b as shown by the two-dot chain arrow in FIG. 4 and the inside of the storage 12 is It is humidified by humidified air. One hour after the start of the Holo (fermentation) process, the controller 50 ends the fermentation program.

  In the temperature-and-humidity control storage (humidity control storage) 10 configured as described above, the control device 50 sprays from the spray nozzle 41 when humidifying with the humidifier 40 when performing the preheating step and the proofing (fermentation) step. The storage 12 was humidity controlled so that water was intermittently sprayed by alternately repeating time and standby time. Since the misty water sprayed in the spraying time is vaporized in the waiting time and distributed in the storage 12, the misty water is sprayed again in the spraying time, so unnecessary water is sprayed. It is possible to prevent the humidity in the storage 12 from hunting largely, and it becomes easy to adjust the inside of the storage 12 to the set humidity.

  In the temperature and humidity adjustment storage (humidity adjustment storage) 10, the control device 50 uses the standby time defined based on both the temperature detected by the temperature sensor 18 and the detection humidity of the humidity sensor 19 to use water from the spray nozzle 41. The humidity of the storage 12 is controlled so as to spray the Specifically, the standby time of the spray nozzle 41 is defined by the temperature and humidity in the storage 12 as shown in FIG. 7, and the standby time defined by the temperature and humidity in the storage 12 is used. The standby time is derived from the detected temperature of the temperature sensor 18 and the detected humidity of the humidity sensor 19. As can be understood from FIG. 7, the lower the temperature, the less the vaporization of water, so the standby time is extended, and the lower the humidity is, the larger the change in humidity due to one spraying is, so the standby time is extended. When this is done, the water in the form of mist is vaporized in the appropriate waiting time and spread in the storage 12, and then the water in the form of mist is sprayed again in the spray time. Therefore, unnecessary water can be prevented from being sprayed, and the humidity in the storage 12 becomes large and it becomes difficult to hunting, and it becomes easy to adjust the inside of the storage 12 to the set humidity. In this embodiment, the control device 50 stores the water from the spray nozzle 41 by using the standby time defined based on both the temperature detected by the temperature sensor 18 and the humidity detected by the humidity sensor 19. Although the humidity control of the storage 12 is performed, the present invention is not limited to this, and the control device 50 determines the spray time defined based on both the detected temperature of the temperature sensor 18 and the detected humidity of the humidity sensor 19. The storage container 12 may be controlled in humidity by spraying water from the spray nozzle 41 using the standby time. In this case, as the temperature is lower, the water is less likely to be vaporized, so the injection time is shortened, and as the humidity is lower, the change in humidity due to one spraying is larger, so the spraying time is shortened.

  In this embodiment, the control device 50 sprays water from the spray nozzle 41 using the spraying time and the waiting time defined based on both the detected temperature of the temperature sensor 18 and the detected humidity of the humidity sensor 19. Although the humidity control of the storage 12 is performed in this manner, the present invention is not limited to this, and the control device 50 controls at least one of the spraying time and the standby time based on the temperature detected by the temperature sensor 18 Alternatively, control may be made to change the waiting time). In this case, as the temperature detected by the temperature sensor 18 is lower, the water is less likely to evaporate, so the spray time is shortened and the standby time is lengthened. Similarly, the control device 50 may control to change at least one of the spraying time and the waiting time (the spraying time and / or the waiting time) based on the detected humidity of the humidity sensor 19. In this case, as the humidity detected by the humidity sensor 19 is lower, the change in humidity due to one spraying is larger, so the spraying time is shortened and the standby time is lengthened.
