Abstract

In a modern kitchen, the processing of food commonly involves sieving of substances (flour) to the required size. However, manual sieving is the most tedious and time-consuming operation in the processing of food substances. The development of a portable sieving machine would therefore drastically reduce the unpleasant work of the manual sieving largely. The machine has a dimension of 300 mm x 250 mm x 200 mm, which is suitable for domestic use and the predominant components for fabricating the machine were the electric motor, pulleys, shaft, belt, bolts and nuts, bearings and connecting rod. They were selected after appropriate design of the various components. After coupling, a test was carried out to determine the average quantity of the substance to be sieved with respect to the time taken to complete the sieving operation and the efficiency of the machine. Experiments showed that the machine has an efficiency of 88.43% when operated electrically and 27.65% efficiency in manual operation. 1.5 kg and 0.47 kg are the respective quantities of substances sieved in 60 seconds. The sieving machine also guarantees hygiene, which is a very important aspect of human life. Furthermore, it saves time and energy as it allows one to carry out other activities in the kitchen while sieving.
