PURPOSE:To eliminate excessive drying and to obtain high quality dried laver without requiring humidifying because raw material laver can be dried while maintaining temperature of drying under the sun, by setting a drying method and a drying condition by a specific procedure. CONSTITUTION:First in drying raw material laver by introducing laver drainboards into a drying chamber, plural drying methods are preset. Then, temperature and humidity of the open air are detected from a temperature sensor and a humidity sensor and evaporation rate is calculated from these values. A drying time of the raw material laver is obtained from the evaporation rate and water content of the raw material laver. Successively, one drying method is selected from the above-mentioned plural drying methods and transporting speed of the laver drainboards is determined by the drying time. |
