A electronic grinder includes a main body and a grinding and dispensing chamber. The top of the main body open but covered by a cap. The main chamber includes a motor connected to a magnetically attached removable blade and propeller. The blade and propeller extend into the chamber when the grinder is assembled. When the cap is closed, the blade and propeller grinds material placed in the chamber and pull air down toward the blade and propeller. When the cap is opened, the blade and propeller function as a fan to generate airflow toward the top of the chamber to dispense ground material out of the chamber. The grinder can also include a microcontroller, a communications device, an infrared volume sensor, a scale, an audible buzzer, a vibration buzzer, and one or more sanitizing LED lights.
