Abstract
Four drying methods using forced-hot air batch type dryer were studied at the Postharvest Research and Training Center, Faculty of Agriculture, Chiang Mai University. The crop dried was Japanese paddy grown in rainy season of 1992.
It was found that drying the paddy continuously with hot air at 40-42 °C with the drying rate of 1.0-1.5% per hour gave better results in term of drying time used. Milling quality was found to be not affected by all the drying methods tested. The head rice yield was in the range of 67-69% while broken percentage of milled rice was 4-7%.
Test result also indicated that percentage of grain cracking found after drying had no correlation with broken percentage of milled rice i.e. high percentage of cracking did not lead to high percentage of broken grain.
