Automated Microcontroller-based smoothie and shake blender and dispenser

This paper focuses on the study, design, and implementation of an automated microcontroller-based smoothie and shake blender and dispenser that can output predefined or customized blends and drinks ready for consumption. The prototype integrates a single microcontroller that handles the algorithm, operation, and process functions of the system. The program was designed to be memory efficient, employing sections of the code linearly and chronologically. The machine is composed of six food grade cylinders and crisscross blades responsible for the storing and blending of the ingredients. Gate valves, which are driven by relays, are incorporated into each container for dispensing. The amount to be dispensed is controlled by timing obtained by rigorous testing which takes flow rates and consistency into account. Process control is obtained by the implementation of a user interface and strategically positioned sensors. The dispensed output undergoes a final blending before it is made ready for consumption
