Development of semi-automatic besan sieving machine

Abstract

A machine is developed to solve the purpose of sieving without much involvement of labours in the work and to replace slow manual process of sieving. In this particular machinery, the machine is operated by a motor which is not directly connected to any shaft. The vibration is created in the machine by placing an eccentric load in the motor shaft & vibration produced in the body of motor is transferred to the sieving box, which is connected by the springs to the main frame of the machine. This machine is fitted with sieve of size 500 micron. This sieving machine can be used for sifting Bengal gram flour to get clean product of desired quality after removing other larger particles present in it. The capacity of this machine was found to be 44 kg/hr when run on full capacity of 5kg sieving material (besan).
