| Abstract | ||||
| The aim of this study was to develop and testing of granular-processing machine for poultry fodder. The tested parameters were: (1) die speeds of 160, 180, 200, 220, 240 and 260 rpm, the die speeds were 80, 90, 100, 110, 120 and 130 rpm (2) hole diameters of 3, 4 and 5 mm (3) Die thickness of 8, 12, 15, 20 and 25 mm. and (4) Moisture content of fodder mixture 5 %, 10% and 15%. The optimum conditions of developed machine were: (1) Die-hole diameter of 3, 4 and 5 mm, (2) Die thickness of 8 mm, (3) Die speed of 220 rpm, (4) Fodder moisture-content of 10 % and (4) Granular dry-duration of 69 h. The obtained results in optimum conditions can be summarized as follows: Granular productivity ranged between 185 – 276 kg/h, Granular losses ranged between 3.03 – 3.78 %, real density ranged between 1.1469 – 1.1491 g / cm3, Granular durability ranged between 88.9 – 90.7 and Machine power ranged between 8.89 – 10.05 kW. The variables affecting the granular productivity, total losses, density were combined into dimensionless groups. The general equations were formulated inside the paper. The production costs at optimum conditions were 12 to 11.71 64.84, 54.17 and 43.84 L.E./ton for die-hole diameters 3 and 4 and 5 mm respectively. | ||||
