PURPOSE:To carry out gentle and proper temperature control of a laver drying machine by case-by-case control for shutter ventilation and fan ventilation based on the values detected by a humidity sensor in said drying machine. CONSTITUTION:Ventilating fans 2, 3 equipped with a fan-driving motor and shutter-driving motor respectively are automatically controlled based on the values detected by a humidity sensor 20 in a laver drying machine 15. Natural ventilation is mode by opening a shutter alone, while forced ventilation is made by opening the shutter with operation of the fans, thus enabling an optimum humidity environment to be secured according to the conditions of raw laver in the drying machine. |
