The authors investigated the drying characteristics of KANPYO using a pilot scale drying equipment which was designed and made acoording to the data derived from the laboratory experiments. The results were as follows;
1. It was recognized that the laboratory data in drying KANPYO, the values of the film coefficient of heat transfer (hc), first critical moisture content (Mf1) and the drying constant (K1) agreed with the results of this pilot scale drying experiments.
2. The following condition was assumed; the heat efficiency of indirect heated dryer in the constant rate drying period will increase not more then 30% of the direct heated dryer even if the the KANPYO was increased up to 5-6 times more than the actual load in this experiment.
3. In order to design the full scale drying equipment of KANPYO, the followings must be considered;
1) The method of putting KANPYO into the drying chamber.
2) The handling of KANPYO before and after drying.
3) The uniform velocity distribution of the drying air and uniform temperature distribution in the drying chamber.
4) The uniform location of moisture content in the dried materials.
5) Improvement in the heat efficiency of the drying equipment.
