Abstract

A cassava pulp sifter for grated and dewatered cassava was developed and evaluated. The machine was evaluated at three operating speeds of 260rpm, 350rpm and 530rpm and masses of 1kg, 2kg and 3kg. It was observed that increase in the speed of operation increased both sieving capacity and sieving efficiency of the machine. Increase in mass, increased sieving capacity and decreased sieving efficiency. The average maximum sifting efficiency and capacity were 95.32% and 613.16kg/hr respectively. All the materials used for the fabrication were obtained locally and the machine has low labour requirements which can be adopted in gari processing industries.

Summary

Introduction

Farmers in Africa have long recognized the values of cassava as an insurance crop against famine and food shortages. Cassava is generally thought of as a poor man’s food. Commercial demand for it is often dropped when cheap imports of wheat, rice and maize have been made available. Cassava is an excellence source of carbohydrate, it has negligible protein content and most of its vitamins and minerals are either washed or cooked away during processing. There are over 1,000 local cassava verities especially in West Africa, better and sweet variation been the major types. Cassava is an important source of energy to man and animals. Cassava can be processed into varieties of food for man among which are gari, Fufu/akpu, starch, abacha, tapioca, kpokcogari and Lafun (cassava flower) among the rural dwellers (IITA,2005)
