| Abstract |
The main goals of the present investigations were to study the effect of using steam-lock on the efficiency of extruder pelleting machine to produce the floating fish feed mill pellets. The performance of the machine as a function of change in type of screw pitch [(5 single screw), (4 single screw + 1 twin screw), and (3 single screw + 2 twin screw)], numbers of steam-lock (3 unit, 2 unit and 1 unit), clearance between the steam-lock and the internal screw case (1.5, 2.0, 2.5 and 3mm), and the width of flat sector in the steam-lock (0.48, 0.98, 1.11 and 1.48 cm) were studied in terms of production rate, pelleting efficiency, pellets bulk density , floating time and energy requirements using an experimental ration of fish feed mill.
The optimum results were recorded with (392.96 kg/h production rate), (93.74% pelleting efficiency), (0.6842 g/cm3 bulk density), (447 min. floating time), and (143.73 kW h/ ton energy requirements) using the optimum operation condition of the machine such as; ( type of screw of 4 single screw + 1 unit twin screw), (number of steam-lock of 3 units), (clearance between steam-lock and internal case of 1.5 mm), and (width of flat sector in steam-lock of 0.048 cm).
