Hand operated cassava chipping machine 

Rapid spoilage of cassava tuber poses  immense difficulty in its marketing and utilization. To avoid heavy post-harvest losses, the roots are customarily processed into sundried chips. Cassava chips are used for preparation of flour which is consumed in the same manner as rice flour.  It also forms a major component in many animal feeds.  In industry it serves as a raw material for manufacturing starch, dextrin, glucose and ethyl alcohol. Machine chipping is highly economical where labour charges are higher or when family labour cannot be employed. Other advantages of this machine are moderate initial cost, accommodating all sizes of tubers, easy to operate requiring no special skill, production of uniform chips and adjustable chip thickness.
The pedal operated chipping machine is a modified version of the hand operated  prototype with additional provision of a pivoted pedal for transmitting the power to the cutting disc through suitable belt and pulley drive mechanism. A trimming knife is also provided on the frame to remove the woody neck portion of the tubers before feeding into the compartments. Four castor wheels are fixed to the legs of the machine to make it portable. Two persons are required for the most efficient operation of the machine, one to trim and feed the tubers and another to rock the pedal. Height of the operator's seat can be adjusted according to the convenience of the operator. The capacity of the machine  increases from 83 to 768 kg/h for increase in chip thickness from 0.9 up to 6.9 mm.
