Cracking of dika nut has presented serious challenges to local processors considering the arduous task it constitutes during processing. A motorized machine that is capable of multiple cracking of dika nuts was designed, fabricated and tested. The major components of the machine include a sliding hammer, a gear unit, a chain conveyor and cracking trays. The experimental machine was evaluated on the basis of cracking efficiency and throughput considering three types of pre-treated nuts (sun-dried, oven-dried and roasted) and two nut sizes (small and big). The cracking efficiency and throughput were: 65% and 8.84kg/h, 63% and 7.75kg/h, 45% and 5.67 kg/h for roasted, oven-dried and sun-dried small nuts; while the corresponding values for big nuts were: 72%... |

The machine of pipes installation of subsurface drip irrigation systems was tested and studied at the Abu-Ghalib farms production (private farm), El-Giza Governorate, Egypt, in growing summer season 2017. The goal of this research was to study the technical and economical evaluation of the installation subsurface pipes for drip irrigation system by Manual method (M) as control, Semi-Mechanical method (SM), and Quad-Raw Machine method (QRM) using different lateral spacing. The QRM method of installation is powered by tractor, the SM method consists of three steps: firstly, the drill plow is drilled under the soil using the tractor, then the pipes are extended in the holes by the labors, and the M method of installation is by labors only for all steps for... |
