Abstract:

This study on the design and construction of a modified cassava milling machine was done, owing to the inability of existing mills to meet the demand of cassava flour in bakery industries. Rational design by drawing and calculations and fabrication in the Centre for Industrial Studies (CIS) FUTO were used to bring this mill to reality. The modified cassava milling machine has a milling efficiency of 82.3%, it is dust free and self-cleaning and due to proper air circulation does not destroy the cassava flour produced by overheating. The cassava flour produced was found to have a fineness modulus (fm) of 0.31, Uniformity index (U) of 0: 1: 9 (coarse: medium: fine) and effective size (D10) of 0.075 mm which is better than that produced by an existing mill (hammer mill) of fineness modulus (fm) 2.32, uniformity index (U) of 4:1:5 and effective size (D10) of 0.085 mm.
