| Field experiment were carried during 2007 at the Sakha Aquaculture Research Station, Kafr El-Sheikh, Governorate, to evaluate the feasibility of using a small expression machine for oil extraction to suit production of fish feed pellets. The effect of some parameters such as, screw speeds (1.50, 1.90, and 2.25 m/s), moisture content of ration (12.8, 16.5, and 22.0 % ), screw pitch (50.0 and 80.0 mm) and two different die shape (Perforated Cylinder - Internal Cone) on energy requirements, machine productivity, pellets bulk density, pellets durability, floating time and pelleting efficiency. The obtained results showed that increasing screw speed from (1.50, 1.90,and 2.25 m/s) tends to increase machine productivity from ( 0.31, 0.37, and 0.47 ton/h), pellets durability from (92.5, 93.4, and 95.66 %), floating time from (270, 295, and 330 min.) and pelleting efficiency from (96.4, 97.2, and 98.4 %), respectively. And decreasing energy requirements from ( 9.27, 8.59 and 7.45 kW.h/ton), and pelleting bulk density from (0.96, 0.81 and 0.74 gm/cm3), respectively. Increasing ration moisture content from ( 12.8, 16.5, and 22.0 %) led to increase energy requirements from ( 7.31, 7.95 and 9.27 kW.h/tom), floating time from (240, 250, and 270 min.) and pelleting durability from (92.50, 93.40, and 95.66 %), respectively. And decreasing machine productivity from (0.31, 0.26, and 0.23 ton/h), pellets bulk density from ( 0.96, 0.90, and 0.86 gm/cm3 ) and pellets efficiency from (98.4, 97.9, and 97.2 %), respectively. | ||
