Abstract:

The operating speed of rotary maize sheller was optimised for its operation at higher operating speeds in pedalling mode, by conducting a simulation study for three sizes of maize cobs at seven operating speeds. The shelling capacity and shelling efficiency of maize sheller for all categories of maize cobs increased curvilinearly with increase in operating speed up to about 70 rpm. The shelling capacity at a particular operating speed decreased with increase in the maximum diameter of cobs. Operating torque of rotary maize sheller for a given size of maize cobs decreased with increase in opera

Abstract:

At present, ginkgo nut shellers have many problems, such as low shelling rate and high damage rate. To address these problems, a multifunctional ginkgo nut sheller was designed. The equipment had functions for shell breaking, shelling, and separation of shell from the kernel. The influencing factors of the shelling process were analyzed. A three-factor two-level response surface test was conducted, and mathematical models for the response surface were established. The influence of each factor on the operation quality was analyzed, and a combination of parameters was optimized. The experimental

A response surface methodology (RSM) has been utilized for investigating the effects of the speed of shelling, melon seed moisture content and the number of beaters of a developed mechanized centrifugal melon shelling and cleaning machine. The machine shells the melon and then cleans the shelled seed from the shells and other impurities. The experiment was based on a central composite rotatable design (CCRD). The results of the experiments revealed that the highest shelling efficiency of 88.5% was obtained from a combination of a speed of 2300 rpm, moisture content of 15% (w.b) and 20 beaters,

Abstract:

Maize shelling is an important post-harvest operation to separate the grains from its cob. Traditional methods involve rubbing maize cobs against each other, rubbing on stones, or hand method. These methods are labour-intensive, time-consuming, and drudgery-prone. Migration from rural population to cities for better livelihoods has creates labour shortage in rural areas during the peak period of maize shelling. A study was undertaken to design, develop, and evaluate the performance of an electric motor powered maize sheller. It consisted of a frame, feeding chute, cylinder, outer cover, rotor

Abstract:

Abstract In response to peanut industry requests to improve the farmers stock grading system, an automated grading system was developed that reduced the variability in measuring most grade factors up to 50%. The automated system reduced sampling error by grading a larger sample while maintaining approximately the same sample processing speed. The system reduced inspector error by simplifying the grading process and eliminating opportunities for mistakes to occur. The system reduced equipment error by replacing outdated equipment with more efficient and effective equipment. Implementing the sys

Abstract:

The strategy of Ethiopian mechanization is to minimize postharvest loss. The methods of crop production were traditional. It involves high drudgery, low quality and quantity, time-consuming, and inefficient operation. To minimize loss, the sheller, thresher, and storage developed. But the performance was not clearly determined for researchers and manufacturers for selection and multiplication. The target of this research was the evaluation of Melkassa maize Sheller. It was conducted at three levels of feed rate: 7500, 6500, and 500 kg/hr., and speed: 700, 650, and 600 rpm. The moisture is 14 p

Abstract:

Rail dark spot defect, also termed as squat failure or shelling, is a rolling contact fatigue failure which occurs frequently on the high speed traffic railway rails. The main goal of this study is to develop a computational model for simulation of the squat phenomena on rails in rail-wheel contact. The proposed computational model consists of two parts: (i) Contact Fatigue Crack Initiation (CFCI) and (ii) Contact Fatigue Crack Propagation (CFCP). The results of proposed unified model enable a computational prediction of a probable number of loading cycles that a wheel-rail system can sustain

To study the effect of operational factors on combine performance, a maize combine with snap roll header was tested at feed rates levels of 69.94 Mg h-1, 85.48 Mg h-1, 124.33 Mg h-1 and moisture content levels of 24.45%, 26.03%, 28.90% respectively. Pre harvest losses increased from 1 to 4% as the maize crop were sun dried from a grain moisture level of 28.90% to 24.45% because the ear shank became weak with decrease in moisture content. The shelling efficiency varied from 96.81% to 98.13%, cleaning efficiency varied from 95.20% to 95.80%, minimum grain damage obtained was 2.1% and minimum tot

Rail dark spot defect, also termed squat failure or shelling, which is a kind of rolling contact fatigue failure and occurs frequently on running surfaces of railway rails carrying high speed traffic, is one of the most dangerous rail failures. The dark spot crack is characterized by a principal crack propagating in the direction of traffic and a second crack growing in the direction opposite to traffic. By using a newly developed two-disk machine, the authors have succeeded in reproducing very similar dark spot cracks to those which appear in actual rails. It is found that the dark spot defec
