ABSRACT - [ Total Page(s): 1 ]ABSTRACTShelling of groundnut pods (Arachis hypegea) by hand is tedious, laborious and unhygienic with low efficiencies. As a result farmer get low income due to amount of broken kernels and a lot of time is lost in the tedious shelling operation. To overcome this problem, pertinent parameters that influence shelling efficiency of pedal operated groundnut decorticator were identified. Pedal operated decorticator were designed and fabricated with chain and sprocket of bicycle and aluminum spike tooth is used and evaluation was done in the department of Agricultural and Bio-Environmental Enginee

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONEINTRODUCTION1.1 Background to the StudyGroundnut (Arachis hypogaea) is a species in the legume or beans family (Ashish and Handa, 2014; Atiku et al., 2014). It was first cultivated in Peru. Its seed contain about 63% carbohydrate, 19% protein and 6.5% oil. Groundnuts are grown in tropical and subtropical climate regions and warmer parts of temperature regions and it is low growing annual plant and has a variety of uses. Prior to its usage however groundnut need to undergo preprocessing which include drying and shelling. Removing of kernels from the pod is generally refer ... Continue Reading
CHAPTER TWO - [ Total Page(s): 10 ]Gardi (Gsrdi (2008) developed rotary type groundnut decorticator-cum-cleaner. The average decorticating capacity, average decorticating efficiency, average cleaning efficiency, percent broken kernels, cost of operation were estimated. The results showed that the values were 120.72 kg/h, 84.69%, 87.76%, 5.7% and Rs 23.28/100kg kernels, respectively. Haque et al., (2009) reported that crushing strength of rubber seeds were found to be 121.1kg/cm2 followed by Jatropha seed (38.1kg/cm2), Castor see (26.5 kg/cm2) and Karanj seed (24kg/cm2) respectively. ...

CHAPTER FIVE - [ Total Page(s): 1 ]CHAPTER FIVE CONCLUSIONS AND RECOMMENDATIONS5.1 Conclusions The following conclusion can be drawn from the performance carried out on groundnut decorticator. 1. The lower the knuckle length of the operator the higher the threshing efficiency of the operator. 2. The lower the weight of the operator the higher the throughput capacity of the machine.3. The average performance of the thresher at average operating speed of 245.4pm are threshing efficiency 56%, unthreshed efficiency 4.7%, breakage 11% and throughput capacity 14.8kg/hr 5.2 Recommendations A ...
