Design and construction of a pedal powered soap mixer for rural dwellers.

Abstract

A bicycle pedal-powered soap mixer is to be designed and developed. The machine is to consist of a chain drive and gear amplification mechanisms that turn impeller blades in a large stainless steel container. where soap ingredients are stirred and blended. The machine is expected to be economically viable, can be used by unskilled workers, save time otherwise spent in traditional mixing and can be adopted for human-powered process units which could have intermittent operation without affecting the end-product. Soap production can be enhanced by making use of this pedal-powered soap mixer, which with little human effort makes the soap to properly mix and trace within few minutes. The study further goes through the design and selection of the different components of the prototype and assembling of the prototype. After construction, it was tested and preliminary testing results are also included in the booklet. The overall project evaluation and the weaknesses of the design are also included in here and the possible solutions in form of recommendations for future designers.
