| Research Abstract |
This research studies on the drying system using the far-infrared heater and drying of agricultural products. This study is the most interesting research subject in Japan.
This developmental scientific research was accomplished for three years. There were to make the trial manufacture of drying equipment with far-infrared heater and to establish the drying method for rough rices, sweet potatoes, SHIITAKE mushrooms and lavers using the drying equipment with far-infrared heater.
In heating experiment of sweet potatoes, surface and inside temperatures of supplied materials were higher than the air temperatures inside drying room. This fact was considered a special characteristics of far-infrared drying.
Maximum reduse ratio of moisture content per one hour for rough rice drying was 17.7%/h. Sweet potoes were dried the moisture content of 20% for 6-9 hours. SHIITAKE mushrooms drying by far-infrared heater were done a method which imitated the tradisional drying method by heating air, and the period of drying by far-infrared was shorter than the drying by heating air. In SHIITAKE mushroom drying, far-infrared drying was an effective drying method. For laver drying, a method according to use far-infrared heater could be established by this research, and was an effective method.
