The Melitta bar-cube touch is a fully automatic coffee machine for professionals in the catering industry. It features a graphical user interface operated via a touchscreen. The interface is highly customisable and can be changed to fit the mood of the café where it is used. This easy-to-operate coffee machine is divided into two operating modes: a public one, for quick and easy selection of coffee specialties, and a sub-level for caterers and personnel, for individual recipe selection, maintenance and statistical evaluation. Thanks to well-structured navigation, users do not get lost, despite the machine’s functional density. All relevant states, parameters and operating steps are displayed on the 8.4-inch touchscreen display.
