Abstract
The warmed-air drying process of laver was observed experimentally and transient behaviors of moisture content, temperature and survival ratio were examined. The process consists of two characteristic periods, i.e. a constant rate period and a falling rate period. At a critical moisture content being a changing point from the constant rate period to the falling rate period, the temperature of laver cellular starts increasing rapidly. The experimental observation indicates that the temperature rise is a dominant factor to determine the survival ratio. Based on the results a best method for drying is presented.
