Developing and Maximizing the Performance of Local Threshing Machine for Small Holding to Suit Chopping and Shredding Crops Residues

Abstract

It was tested in Rice Mechanization Center for threshing and winnowing of rice crop. It was used to chop and shred rice straw crop to maximize the performance of this machine and increasing yearly working hours, Results of the original machine showed that, it can not cut rice straw into small pieces without accumulation problems occurred in the threshing chamber especially with feeding of complete stalks sample at high moisture content. This problem causes wasting time, less productivity, and increase cost. Consequently, it is necessary to develop this machine for the young farmer to cut some crop residues as rice straw, corn stalks and cotton stalks. The machine after modification was operated at four

Design, Fabrication and Performance Evaluation of Wheat Crop Thresher for Small-Scale Farmers

“…Generally, the results indicated that total grain damage increased with increasing the cylinder speed, fan speed, concave -drum clearance at rasp-bar type cylinder. Similar results were achieved by Kolganov (1956), Vas and Harison (1969), Singh and Kumar (1976), Kumar and Goss (1979), Joshi and Singh (1980), Sharma and Devnani (1980), Singh et al (1981), Anwar and Gopta (1990), Alonge and Adegbulugbe (2000), Sudajan et al, (2002), Khazaei et al, (2002), Johnson (2003), Khazaei et al, (2003), El-Haddad (2004, Vejasit and Salokhe (2004), El-Haddad et al, (2006), Askari Asli-Ardeh et al, (2008, Chimchana et al, (2008) and Ponican et al, (2009).…”

“…Generally, the results indicated that threshed grains increased with increasing the cylinder speed, fan speed, concave -drum clearance at rasp-bar type cylinder. Similar results were achieved by Singh and Kumar (1976), Ige (1978), Sharma and Devnani (1980), Desta and Mishra (1990), Hadad (2000), Simonyan and Oni (2001), El-Haddad (2004), Vejasit and Salokhe (2004), Adewumi et al, (2007) and Radwan et al, (2009). Arnold (1964) reported that increasing concave length increased concave separation.…”

“…Results indicated that the drum speed had the highest effects on the intensity of damage. El-Haddad (2004) designed and manufactured chopping, threshing and winnowing machine suitable for the requirements of some crops residues recirculation. The experimental results showed that the visible grain damage increased as the cylinder speed increased.…”

“…Simonyan and Oni (2001) reported that the threshing effectiveness was also found to be affected by the cylinder speed. El-Haddad (2004) designed and manufactured chopping, threshing and winnowing machine suitable for the requirements of some crops residues recirculation. The experimental results showed that the threshing efficiency increased as the cylinder speed increased.…”

Maximize the Utilization of some Residuals Food Manufacture

“…World orange production is estimated at 60 million tons per annual, while the annual production of orange peel waste is 32 million tons (Igolima et al, 2023). El-Haddad (2010) developed the local threshing machine for small holding to suit chopping and shredding crops residues. He found that the percentage of small cutting lengths were increased by increasing cylinder speed and feed rates and decreased by increasing the moisture contents.…”
