ABSRACT - [ Total Page(s): 1 ]ABSTRACTThe traditional methods of threshing of crops are inefficient, laborious, and time consuming and low out put. The existing fabricated machine was observed during preliminary testing to have low performance. In the light of the above mentioned problems, there is need to modify and testing multi-crop thresher to threshed grain at optimum speed. The threshing machine consist of the following component: Hopper, frame, beater, sieve, pulley, grain outlet and chaff outlet. The factors consider ... Continue reading---

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE INTRODUCTION1.1 Background of the StudyCowpea is a grain legumes appears to have originated from west-African, very widely in Nigeria were there are many wild weedy species in both savanna and forest zone (Steel, 1992).Cowpeas are now widely distributed throughout the tropics and sub-tropics. They are grown in India, south eastern Asia, and Australia the Caribbean, southern united state and throughout the low land tropical Africa. Nigeria alone ... Continue reading---
CHAPTER TWO - [ Total Page(s): 4 ]CHAPTER TWO LITERATURE REVIEW2.1 ThreshingProcessThreshing is defined by Andrew(2005) as the process of loosening the edible part of cereals grain (or other crop) from the scaly, inedible chaff that surround it. It is a step in grain preparation after harvesting and before winnowing, which separate the loosening chaff from grains. Threshing may be done by beating the grain using a flail on a threshing floor. Another traditional method of threshing is to make donkey or oxen walk in circle ... Continue reading---

CHAPTER FOUR - [ Total Page(s): 1 ]CHAPTER FOURRESULT AND DISCUSSION4.1 ResultThe experimental result obtained from the experiment is as shown in table 5.1 and 5.2 the raw data is as shown in appendix.4.2 DiscussionsA multi-crop threshing machine was modified and evaluated for performance. The threshing efficiency, unthreshed efficiency, breakage efficiency and throughput capacity were 90.1%, 9.5%, 20.1%, 143.4kg|hr for feed rate of 2kg and 90.9%, 9.1%, 14.11% and 251kg|hr for feed rate of 3kg respectively at a consta ...

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVECONCLUSION AND RECOMMENDATION5.1 Conclusion The following conclusion was drawn from the performance carried out on the multi-crop thresher.I. The speed of the blower was obtained which reduces the blown out of grains from the outletII. The feed rate of 3kg favors the constant speed of 300rpmIII. The higher the feed rates at the threshing drum the higher the throughput capacity.5.2 RecommendationBased on the result and conclusion, the foll ... Continue reading---
