| Summary: | The FYP project is about the design and analysis of sago drying machine. The increasing demand of sago flour in various uses mainly in food industry indicates the need
to enhance the productivity of sago. The project is to design a machine to make the workers easier in drying process and enhance the efficiency of drying at the same time. The main problem focused in this project is the design and mechanical analysis for the dryer. The mechanical analysis is focused on the tray, support and mixer. Simulation and mathematical model is done to analyse the safety of the product for operation. The mixer is driven by a bevel gear with gear ratio of 3. The rotary motion is transmitted along 15 mm shaft. The motor used is 100 W gear motor and the speed is 200 rpm. The output speed is 70 rpm. One batch of sago flour is 20 kg with expected drying time of 2.7 hours. The simulation shows that the design will not fail as the stress acting on it is within limit of ultimate tensile stress. Small deflection requires no more support at bottom of the tray
and tray support. The parts will not fail or break. The simulation results is validated with calculation results showing the simulation can be used to analyse the safety of design structure. The pinion bevel gear have 15 teeth and driven bevel gear have 45 teeth. Gear ratio is 3 and module is 2.5. Input shaft is made up of steel AISI 1050CD with 15 mm diameter whereas output shaft is made up of AISI 1006HR with 18 mm diameter. Static and dynamic analysis shown the design is within the fatigue factor of safety limit of 1.5. The static and dynamic analysis prove that the machine parts operates in a desired safety
factor, indicating that the machine will be safe to operate without failure. |
