Abstract

The effect of flowrate. height. moisture contents and thickness on the airflow resistance of cassava chips was determined Airflow resistance was measured at air velocities (fully to 1/4 opening of blower) ranging hone 19 m/s to 1.3 m/s, height from 0 5334 m to 0 1524 tn. thickness from 5 mm to 15 mm and moisture content from 5% to 05% wet basis It was found that for velocity range of 1.3 m/s to 19 m/s, thickness significantly effects pressure drop at 5% level of significance. In addition. bulk density was found to be significantly affected by moisture content, thickness and height at 5% level of significance A linear model for hulk density as function of moisture content and slice thickness was developed Relationship of static pressure drop versus airflow rate using moisture content levels, height and thickness as factors were fitted to three models (Shedd-type equation, Hukill & Ives equation, and Ergun-type equation) From the Sloan Square Error (MSE) and visual inspection of the experimental and predicted curve. the Shedd-type equation is the best model that could represent the static pressure drop versus airflow rate for rootcrops such as cassava chips
