Heating: Ø 40 mm, steel, conical Number of control levels: Scale of trace elements for 30 macrocomandos + nine indicators Flow rate: Homogeneity between 3.5 and 5.5 g/sHopper: 300-400 g of Maltese coffee grounds: 160 g Weight: 3.2 kgDimensions: 13/40/24 (cm)The manufacturer points out that the Sette grinders are used to grind 1 kg of coffee per day, including up to 100 g of grind after espresso. In addition, 150 g of coffee is ground at a time. The interval between grinding cycles must be at least one minute. With 40 mm steel bulbs, 3.5 to 5.5 g of coffee can be transported per second, depending on the particle thickness. The manufacturer Etzinger calculates their optimum use over several years. Cleaning is very simple, so the bulb can be easily removed and refitted.
