Development of an Improved Domestic Grinding Machine

Abstract

The major thrust of this paper is the development of an improved domestic grinding machine operated and mostlyused in kitchen for the grinding of vegetables, spices and grains of any form. The challenges facing the separation ofgrinded ferrous metallic particles from the products grinded have been solved through the introduction of magneticsubstance at the exit compartment called extractor. The testing of the machine was extensively carried out on dried(cayenne) pepper with 97% efficiency of the operation. The construction of the work is simple and it employs themaximum utilization of locally sourced materials, which are readily available hence, a reduction in its total cost.
