After paddy and wheat maize is the third most important crop in India. Maize is known as king of fodder and queen of cereals due to its great importance in human and animal diet. The traditional shelling of maize is by using hands by rubbing the maize cobs, or after complete drying rubbing the maize cobs open each other or on any hard frictional surface. These methods are tedious and time consuming also involves drudgery like muscular pain. Here the study was undertaken for the small and marginal farmers to survey the different shelling methods used by them for maize. In this project we have solved the problem by providing low cost and hand operated maize sheller having good efficiency as well as cost economy for small and marginal farmers. Here the small scale maize sheller consist of a rubber tire mounted on a frame and a shaft attached to it below which a concave is provided, feeding of sundried maize with moisture content 10-20 per cent is done at the clearance between the tire and the concave so that rubbing action occurs between the tire and the concave and shelling of maize will be there. The clearance between concave and tire is adjustable so any size of maize can be shelled. Here the shelling productivity of hand operated maize sheller was found to be higher as compared to manual shelling and shelling efficiency decreased with increasing the moisture content and increased by increasing rotational speed.
