Abstract
This report describes drying methods for laver so that it can dry with high quality and efficiency. A far-infrared drying equipment was made with a bar heater. The drying characteristics of laver were tested by this epuipment. The following results were obtained, 1. During laver drying,the wave lengths which are selectively absorbed by the lavers existed in emitted far-infrared rays. 2. The constant drying rate and the falling drying rate periods clearly appeared in the drying characteristics of lavers. The constant drying rate period was an effective period in order to decrease the drying times. 3. The drying of lavers needed an air stream flowing along on the laver surface. The optimum velocity of the air stream was 0.75 m/s, and the drying times were shorter on the laver surface to circulate the air of drying room.
