| Abstract | This research aimed to design and develop a small shredder machine for shredding vegetables waste and fruit peels. The procedures were studying basic physical properties of materials, designing, constructing and testing the performance of the shredder machine.The shredder machine weighed 45 kg. It consisted of a steel structure, a feeding hopper,cutting blade set (23 curved blades 160 mm long, 2.0 mm thick), fly wheel, powertransmission sets, material rails and 1/3 hp electric motor. Seven types of plants includinglemongrass stub, lemongrass leaf, pandan leaf, Thai morning glory, Beijing grass, passionfruit peel and pomelo peel were tested at cutting blade speeds of 500, 600, 700, 800 and900 rpm. The test results showed that the machine can cut materials at all speeds tested.The amounts of cutting were directly correlated with the cutting speeds. At the cutting speedof 700800 rpm the machine could cut 71148 kg/hr of tested materials using electricalpower of 0.00090.0033 kWh/kg. At these speeds the cutting machines worked smoothlywithout vibration, so the cutting speed 700 rpm was selected for operating the machine.The machine could cut 6 types of test plants except pomelo peel. The average cuttingcapacity was 112.3 kg/h with average electrical power consumption of 0.0013 kWh/kg.Economic analysis revealed that the machine cost was 23,000 baht and it was furtherfound that the cost per cutting unit (baht/kg) at small cutting amount was high but wouldbecome lower when the amount of cutting increased. For example, when the cutting amountincreased to 60,000100,000 kg/year (150.5212.0 days), the cutting costs were between0.730.75 baht/kg. |
