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.

本研究以远红外线加热器为干燥系统，对农产品进行干燥。这项研究是日本最有趣的研究课题，这项开发性科学研究历时三年完成。进行了远红外加热干燥设备的试制，并建立了利用远红外加热干燥设备对稻谷、甘薯、香菇和紫菜进行干燥的方法，在甘薯的加热实验中，进料表面和内部温度均高于干燥室内空气温度。稻谷干燥的最大小时水分利用率为17.7%/h。甜土豆在20%的含水量下干燥6-9小时。采用远红外线加热器对香菇进行干燥，模拟了传统的热风干燥方法，远红外线加热器的干燥时间比热风干燥时间短。在香菇干燥中，远红外干燥是一种有效的干燥方法。通过本研究，可以建立一种针对紫菜干燥的远红外加热方法，是一种有效的方法。
