For making food products like laddu (Indian sweet), rice balls input material is to be pushed ahead as well as pressed to solidify and take a specific form or shape. For extrusion of food products in food industries a simple design of feed screw and barrels is used and is a traditional way for extruding food for further processes. The feed screw can contribute for optimum efficiency rate with proper output of extrusion. The proposed design of auger type feed screw pushes the material ahead like a screw conveyor and also applies proper pressure. The proposed design can be used for increasing the overall efficiency of a food product company by increasing the rate of production as the auger type feed screw is designed to accommodate and process larger volume as compared to the traditionally designed feed screw. The casing designed thus helps the auger type feed screw in gaining optimal output. The paper also proposes the calculations and parameters of the auger type feed screw adhering to the torque and power requirements. .
