The critical moisture content of excrements filtered has been determined to be about 200% (D. B) based on the characteristic curve for drying, obtained by pilot plant tunnel dryer method. Temperature, humidity, flow rate and thickness of the feed material, and direction of air flow had large effect on drying in the constant rate period, but had little effect in the falling rate period. The optimum operation condition for drying with tunnel dryer had been investigated.
