ABSTRACT

The main aim of this project is to design modification and fabrication of a groundnut roasting and decorticating (peeling) machine for better efficiency. This paper will also describe the design of various parts of the machine. This involves processes like the design, modeling and analysis ofsome parameters etc. The performance ofthe machine will be evaluated in terms of capacity, the rate offeed and efficiency. This work entails the design modification groundnut roasting and decorticating (peeling) machine. The decorticating machine which will be powered electrically by 1 Hp, a blower, 1500rpm electric motor and also comprises ofthe roasting chamber, sieving, peeling unit etc and is opened directly to the decorticating unit. The peeled groundnut seeds and the chaffs fall directly into the cleaning unit where an installed fan blow away the chaff and the seeds are collected directly through an opening below the decorticating unit. The machine will be made from locally sourced materials and it can be used in both urban and rural areas. This work will be focused on the design and development of an integrated groundnut roasting and decorticating (peeling) machine which will electrically be powered by a Ihp motor. The machine will have the capacity of roasting and decorticating of groundnut with a separating efficiencies of 91.67% respectively. The machine will be fabricated from locally sourced materials, which will make it cheap and easily affordable and also easy and cheaper to maintain. It will also be of light weight and comprises of the hopper, roasting chamber, separation chamber, peeling chamber, the blower unit etc. The machine will be tested for performance and efficiency after the fabrication is completed.
