Design and Fabrication of a Flour Mixing Machine

Abstract

A mixing machine was fabricated to eliminate the local process of
mixing flour for both domestic and commercial uses. The uniqueness
of the machine rests on the fact that the mixer basin as well as the
stirrer can be changed at will to suit the nature of materials being
mixed. The machine was developed to enhance the hygienic
processing of flour into dough for bread baking and other related
products of flour for human consumption. The mixer eliminates the
unhygienic and laborious indigenous process of preparing it. The
frame was made of mild steel U and square channel (1270mm x
1000mm) metal sheet welded to cover the whole frame except the
underneath. The U-Channel square base housed the gearbox of 1:40
and the transmission system. The machine was designed to mix 25kg
of flour and ingredients within 25 minutes into dough. The machine
has 87% efficiency. The machine parts consist of 2.5hp electric
motor of 2840rpm, driver pulley, V-belt, gearbox, stainless basin,
stirrer, shaft, etc.
