The Design of a Pedal Driven Pulverizing and Sieving Machine for Dewatered Grated Cassava

Abstract

The post-harvest operation of cassava is still being done manually and therefore labour intensive. The need to mechanize this process makes it necessary to have a machine that will perform some of these processes. This paper presents the design of a pedal driven pulverizing and sieving machine for dewatered grated cassava. The components design includes the sieve bed mechanism, screening material, chain, shaft and pulverizing cylinder. This involves the mechanization of pulverizing and sieving of dewatered grated cassava. The Machine is designed to be driven like a bicycle, which sends rotary motion to the system for the desire work
