Abstract: The aims of this research were to study the effects of type of impacted material and size of impeller on hulling quality of centrifugsl rice dehusker. Theprinciple of this machine was applying the shear force between rice kernel and impacted cieculae to separate husk from rice kernel. This type of rice dehuskerwasinterested due to a small in size, low energy consumption and ease of use. The study were investigated the quality of 14% (w.b.) rice hulling using different types of impacted material, different size of impeller on hulling performance of Hom Mali Rice. The 3 sizes of impeller diameter (5.5 cm, 8.8 cm. and 11.9 cm. ) and 4 type of impacted material (sandpaper No. 240 and 320, black rubber and hard resin ) were experimented combined with the 4 levels of feed rate and 4 levels of impeller speed (3,226 3,703 4,110 and 4,431 rpm). All experiments were studied with 3 replications. The results revealed that using the medium size of impeller and impacted material of blank rubber provided the best performance under condition of the feed rate of 16 grams per second and impeller speed of 3,326 rpm. The efficiency of quality and quality of hulling were 79.23% and 66.56% respectively.
