ii. Digital Weighing Machine
This is a device to measure weight of a material. This is used to measure the mass and weight of groundnut pods before and after threshing. It in the decorticating machine. The make and model of use weighing scale was Elmakarus postal scale (ES-SK02) with sensitivity of ± 2. Plate 3.3 shows the pictorial of the digital weighing scale.
iii. Stop Watch
A digital stop watch having least count of 0.01 second and with maximum capacity of 10h was used for recording the time.

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 t ... Continue reading---

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 pr ... 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 J ... Continue reading---

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%, unthreshe ... Continue reading---
