Abstract:
A sieve was a device that used a woven screen, such as a mesh or net, to separate desired elements from undesired material or to characterise the particle size distribution of a sample. the main problems of the sieve was it required a lot of human energy and requires a long time to sieve the flour. The sieve could not sieve in a large amount due to their size and capacity and made the user felt tired quickly made it a massive chore to did. Methodology was the rules or procedures used to implement the project in detail. Dinamo grater was our project concept which was this project used rotation from electric power to made this machine moved automatic. The weight of flour that could been sifted by the machine in the one time was 5 kg , require 30 minutes to complete one cycle of sieving and estimated 20 kg for this machine weight. Project planning and phases were made and being implemented during the project production in ordered to ensured the process went smoothly. It also helped to as a reference to ensured that we achieve the objective on time. For recommendation , our project would sifted 10 kg flour in one time , had a 10 kg weight and could sifted 5 - 20 minutes for completed one cycle of sieving.
