Design and fabrication of a modified fish feed pelletizing machine

Fish feed pelletizing machine was designed and fabricated with the aim to improve on existing local pelletizers; encourage technology fish farmers who may be faced no power supply. It mainly consists of hopper, chamber, frame, bolts nuts, screw conveyor, cutting mechanism, die plate transmission unit dual operation mode. Performance evaluations improved as well were carried out results showed that both machines able produce pellets 8 mm average diameter 10 length. The overall mean values pelleting capacity, specific energy consumption efficiency 1.20 kg/min, 0.010 kWh/kg 97.09%; 0.89 0.014 75%, respectively. These imply could a ton feeds for 14-hour daily consume approximately kWh compared would 14 kWh. capacity is quite better than machine. obtained impressive only about 2.91% mix might lost 25% by Therefore, recommended use small-scale mill pelletizers have comparable higher losses couple lower efficiency.
