Modification Of A Double Crossed Beater Hammer Milling Machine For Bambara Nut Processing:- Uzuegbu Kingsley K

ABSTRACT

This study is all about the modification and development of a double cross beater hammer milling machine for bambara flour processing which will reduce drudgery, enhance milling efficiency, save time and energy. This machine comprises of the hopper, milling chamber, double cross beater of which the machine is designed to operate using a 15hp electric motor. The performance evaluation ofthe developed double cross beater hammer milling machine shows that the machine can grind 10kg of bambara nut in 76 seconds unlike the existing single cross beater hammer milling machine which takes 140 seconds. This shows that the time taken to grind bambara nut in the developed double cross beater hammer milling machine is lesser. We therefore encourage the use of a double cross beater hammer milling machine in bambara flour processing because of its numerous industrial benefits which include high productivity and flexibility of grinding a large variety ofBambara nut. The cost ofdeveloping this double cross beater hammer milling machine is four hundred and twenty thousand naira only (420,000).
