A test unit of a microwave dryer was constructed and tested for cooking and
drying foods with high humidity. The rest identified the moisture evaporat
ion curve and the drying curve. Based on these curves, a four-stage drying
process was introduced. A local taro, Binlang-Yu, was put through the unit,
and the measurements show the feasibility of microwave drying of foods wit
h high humidity. Significant efficiency improvements with microwave drying
were obtained. (C) 1999 John Wiley & Sons, Inc.
