PURPOSE: To control the humidification amount of a solid culture device in high accuracy by measuring the dry-bulb temperature and the wet-bulb temperature of an air flow to be sent to a solid culture device on the upstream side of a humidifying device, calculating the measured data, an air quantity and the amount of humidifying water and supplying a necessary amount of water. CONSTITUTION: In an air flow sent to a main body 5 of a solid culture device, a signal from a temperature sensor 9 set in a blowing duct 8 is inputted to a blast temperature regulator 3, and an adsorption damper 10, a middle damper 11, an exhaust damper 12 and a cold water pump 13 are controlled to regulate air sent to the main body 5 of a solid culture device. A dry-bulb temperature and a wet-bulb temperature are measured respectively by a dry-bulb temperature sensor 1 and a wet-bulb temperature sensor 2 set on the upstream side of a humidifying device comprising a humidifying nozzle 6 laid in an air harmonizing device 7. The amount of humidifying water so as to attain a fixed temperature is computed by a calculator 16 from the measured data, an air quantity measured by a wind velocity sensor 4 and humidifying efficiency of the humidifying device. A necessary amount of water is supplied from the humidifying nozzle 6 by using a pump 17 and a control panel 18 to the solid culture device to control the humidification amount of the solid culture device. |
