Development of an Improved Garri Sifting Machine (original) (raw)

Cassava is a multipurpose crop for man and livestock. Cassava starch is an ingredient in the manufacture of dyes, drugs, chemicals, carpets and in the coagulation of rubber latex. The way forward is the design of appropriate mechanical device and system for sieving dried cassava flakes (Garri). This project seeks to design and fabricate an improved garri sifting machine. There is need for the development of commercial scale garri sifting machine where the roasted garri can be properly monitored. Some design considerations used in this project include efficiency, portability, and safety of operations. Adequate care of chemicals present in cassava juice was considered in selecting materials for fabrication of the machine. The machine was damped to reduce noise pollution during its operation. The machine runs on a single phase 1 HP. electric motor at a speed of 1400 RPM. The result obtained from performance evaluation test showed a sieving efficiency of 92.5% as compared with machine e...
