Electrical actuation of the grinder of an automated coffee

Abstract

The paper refers to espresso coffee machines high quality and some possibilities to increase the level of automation and productivity, while the designed PV system ensures the independence to the machine from the grid power. Existing machines require manual adjustment of coffee grinder depending on the quality of coffee beans. To eliminate this flaw an adjustable electromechanical system with DC servomotor and numerical control of coffee grinder has been developed and implemented. Computer simulation results demonstrate the functionality of the proposed electromechanical drive system of the coffee grinder.
