Development of a prototype automatic mortar and pestle / Muhammad Aliff Mohd Zainuddin

This dissertation introduces an innovative automated mortar and pestle prototype designed to overcome challenges in traditional substance grinding. The primary aim was to create an efficient device automating substance crushing while minimizing manual effort. Utilizing stainless steel, aluminium, drills, and hand grinders in fabrication, the prototype incorporated a crank and slider mechanism, silicone spatula, and DC motors configured in a mortar and pestle setup. The methodology involved detailed design processes and calculations, specifically torque and power calculations to determine motor specifications for the crank and slider. The core of the design revolved around implementing a crank and slider mechanism as the primary structural element. Thorough testing with substances like onions and garlic showcased the final prototype's prowess, with its reciprocating pestle and rotating mortar, powered by two DC motors. This demonstrated significant advancements in speed and accuracy over
traditional manual methods. The results hint at potential commercial applications with further enhancements, marking a notable stride in substance processing technology
