Abstract

The results showed that the knife sharpening angle and blade speed significantly affected the waxy maize shredder capacity, shredder loss and shredder efficiency (P < 0.05). The 30° knife sharpening angle and 1100 rpm blade speed resulted to high shred capacity, efficiency and low shred loss, hence these were selected as the optimal factors for developing the shredder. The size of the stalks was 2.57±1.25 cm, which is suitable size for animal feed. The engineering economic cost analysis showed that the average working cost was 0.35 baht/kg, the break-even point was 190 hours/year, and when considering the 600 hours/year of work, the payback period was 1.4 years.
