ABSRACT - [ Total Page(s): 1 ]ABSTRACTA motorized rice de-stoning machine was designed, fabricated and evaluated for performance. The traditional method of rice de-stoning machine characterized with a lot of deficiency in terms local rice containing smaller stones during de-stoning operation. A lot of energy is expended in solving the problem of operation. The rice de-stoning consists of the following part: Hopper, Vibrating Sieve, Machine Frame, Pulley, Eccentric Shaft, and Blower. The factors investigated were feed rate (500g/min) and variety off rice (Bokola, Kodoqiche, AlhajiA’aba). The result of the evaluation

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1. INTRODUCTION1.1 Background of the studyRice (Oryza sativa) is a cereal belonging to the Gramineae, a large monocotyledonous family of some 600 genera and around 10,000 species (Wibberley, 1989). It is valued as the most important staple food for over half of the world population (International Year of Rice, 2004) and ranks third after wheat and maize in production on world basis. More than half of the world’s population depends on rice as the major source of calor ... Continue Reading

CHAPTER THREE - [ Total Page(s): 9 ]Where, D = maximum diameter of rice grain size (2.3mm); and Câ‚’ = coefficient of opening (3.5). Therefore, d = 1.9mm. Motor power, = 0.37KW Motor speed, = 1400rpm The velocity of the motor, ... Continue Reading
CHAPTER FOUR - [ Total Page(s): 2 ]CHAPTER FOURRESULTS AND DISCUSSION4.1 Results The results of the experimental raw data of physical properties of the three varieties of the rice selected (Bokola, Kodoqiche, AlhajiA’aba (Orizaglaberrima) where presented in appendix A. The raw data obtained from the rice de-stoner is as shown in appendix B. The average values of physical propertiesobtained from the three varieties is as presented in table 4.1. ... Continue Reading
CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVECONCLUSION AND RECOMMENDATION5.1 ConclusionThe development and performance evaluation of a rice destining machine was successfully carried out with this work with average impurity level attained as 7.8, average rice separation efficiency as 81.0%, average stone efficiency as 77.3% and the average tray loss as 14.8%. The machine was tested and found partially capable of de-stoning rice due to losses during the testing.5.2 RecommendationsThe rice de-stoning machine designed, fabricated and evaluated still need some improvement. The following were hereby suggested for furt ... Continue Reading
