The Predication of Relationship Between Harvesting Moisture Content and the Most Convenient Rice Moisture After Drying to Obtained the Highest Head Rice Yield When Rice is Dried in Drying Machine

Abstract

Rice is dried after harvesting and milled before consumption. But cracklings occur on rice while rice is being dried with hot weather. Depending on cracking amount milling rice yield will be high or low. In order to minimize breakage during the drying process, the relationship between harvesting grain moisture content and storage moisture content was examined. Thus the highest head rice yield could be obtained. For that object, rice samples that were harvested in different harvested moisture content, were dried with hot weather in prototype dryer which was designed for this object. Rice samples were dried to different moisture and head rice yield was predicated after drying process, thus the moisture of dried rice which was obtained maximum head rice yield was found. According to the data, relationship between harvesting moisture content and the moisture of dried rice on prototypes drying machine is significant as statistical. A regression equation was obtained with data from drying process. With this equation, the most convenient moisture to obtained highest head rice yield after drying can be predicted. The most convenient rice moisture after drying =( 4.66 + 0.59 x Harvesting moisture content)+/- 0.54.
