Design and Development of a Hand Operated Grinding Machine

Abstract

Grinding food items is a very important part of food processing. This
paper is focused on the design and fabrication of a manually operated
domestic foodstuff grinding machine whose cost is affordable to the
common man while ensuring durability, maintainability and reliability.
The conventional prime mover is replaced with a hand operated geared
assembly which will reduce the total cost of the assembly while
maintaining the grinding quality and capacity of the machine. The results
showed an average mass of residue from the constructed machine after
drying to be 63g and with a finness of less than 500µm particle size, the
overall percentage of the constructed machine was 75percent.
