| Abstract | ||||
| An innovated machine was manufactured for extracting pomegranate seeds distinguished of high productivity, simple design and low seed damage. The extracting machine was depending on an innovative system to extract the seeds from the peels and flesh by vibration. Experiments were carried out to study some different operating parameters which were six different exciter frequencies S1, S2, S3, S4, S5, and S6 corresponding to 0.0, 28.1, 52.0, 75.9, 101.2 and 121.4 Hz respectively, five different sieve amplitudes of 10, 20, 30 40 and 50 mm and four different separator shaft speeds of 100, 200, 300 and 400 rpm, affecting the performance of the manufactured machine. The machine performance was evaluated in terms of machine productivity, total seed losses, extracting efficiency, specific energy and criterion cost. The experimental results revealed that machine productivity (0.25 Mg/hr.), total seed losses (6.01%), extracting efficiency (70.19%), specific energy (8.8 kW.hr./Mg) and criterion cost (400 LE/Mg) were in the optimum region under the following conditions of 101.2 Hz exciter frequency, 40 mm sieve amplitude and 200 rpm separator speed. | ||||
