I'm curious about how commercial, fully auto espresso machines do the job? For one example, Melitta's C35 machine that's used by McD's comes to mind, but I know there are several others in use. Do these machines go through the usual grind, dose, tamp and extract via some type of group only with each of these steps executed automatically? If so, how do these machines handle the pucks after extraction? Or do they produce an extraction from a different set of steps?
