MANUFACTURING AND PERFORMANCE EVALUATION OF A COMPATIBLE UNIT TO PRODUCE ANIMAL FEED PELLETS

The main objective of this research was to manufacture and evaluate a compatible unit including mixing and pelleting to produce Rabbit feed pellets formula in one operation. The compatible was evaluated under operating parameters including four different retention time (2, 3.5,4 and 5min) and four L/D ratio (5:1 5.5:1, 6:1and 6.5:1) were investigated under the above mentioned parameters. The optimum results compatible unit were die L/D ratio of 5.5:1, 3.5min of mixing retention time, and rollers teeth width of 10mm. 427.87kg/h production rate 37.96 kW.h/ton energy requirement.88.29% mixing efficiency, 0.671gm /cm3 bulk density, 93.21% durability, 49.01N hardiness, and 566.36 LE/ton using residues formulation including black seed meal.
