Coconut automatic machine grinder / Nadiatul Aiman Abd. Hamid and Azizul Hakim Samsudin

Coconut is one of the main ingredients in the food industry, especially coconut milk and grated coconut. The existing coconut grater require a lot of energy to handle, too large for small scale used and the safety is highly questionable. To overcome the problem, a machine was design to grated coconut automatically and increase its safety. Morphological approach was used to determine the proper design for the coconut automatic machine grinder. Meanwhile, torque theory was used to determine the optimal sizing of the motor that able to rotate the grater and able to withstand load during grating process. SOLIDWORK was used to perform the stress and deformation analysis towards the frame of the product. The results of the calculation were able to determine the optimal size of motor that able to rotate the grater and able to withstand load during grating process. Furthermore, the output of the analysis using SOLIDWORK also shows positive results where no failure indicator appears in the stress and deformation analysis. To conclude, this coconut automatic machine grinder was successfully designed, fabricated. and works perfectly. This product has been tested and it able to grate a coconut for small scale with the increase of safety index
