Abstract
The traditional method for drying of marine products is the warm air drying, which needs a long drying time and the quality of product is poor. Then we have developed the microwave irradiation drying under reduced pressure condition as a new drying method replaced by the warm air drying. The drying time was successfully shortened to about 1/20 of the warm air drying and low drying-temperature results in the good quality. The purpose of this study is an enhancement microwave drying by introducing external air. We found that the external air plays a role as carrier gas of water vapor and increase the drying rate.
