It is necessary to establish the rational drying method that takes the moisture contents of a single rice grain into consideration. The changes in the distribution on individual moisture contents of rough rice dried in a circuration type dryer were reported in the previous paper. In the present report, in order to develop the uniform moisture content of individual grains, a drying of rough rice in a circulation type dryer was paused for a time was adopted. And the effects of the pause during drying on the quality of rice, particularly the cracking of rice kernels were investigated. The results showed that the short pause of drying decreased the unevenness of moisture content of individual rough rice kernels and reduced the cracking drying. And the pause of drying elevated the measuring accuracy of moisture during drying and reduced the decrement of moisture contents of brown rices after drying.
