Hand operated cassava chipping machine 

The low palatability of the cassava based feed  due to the powdery nature of flour gave way for the particle size up gradation by the process of pelleting, granulation or globulation. It also help to make handling easier, reduce the volume to weight ratio and maintain uniformity in size and shape of the final products.  The centrifugal granulator developed for feed preparation based on cassava flour offers better scope for the in situ consumption and farm scale processing of tubers.
The granulator consisted of a cylindrical drum  mounted horizontally on a shaft installed on a  trapezoidal angle  iron frame work The sides of the drum are covered leaving provisions for spraying  water using a knapsack sprayer while the granulator is  in operation. A rectangular slot with a cover is provided at the down slope of the drum for feeding the materials and to take out the granulated feeds.  The machine can be operated by manually and also by an electric motor (¾ hp). Flours of different feed formulations ie., cattle feed and poultry feed were fed to the granulator, started  granulating by rotating the machine, simultaneously spraying  the  water using a knapsack sprayer and the resulting granules were dried. The capacity of the machine worked out to be 20 kg/h
