I think it is there to distinguish it from an espresso machine.

in the quote "Bohnen-Kaffeemaschine" is contrasted with "Portionen Maschinen" (the spelling is wrong). It seems therefore that the former is an authomatic coffee machine with integrated mill rather than a mere "Bohnenkaffee" machine.

another possibility: automatic coffee machine

this might be an option, if you want to make it really obvious. but since you say it is used at a trade fair, I think the 'automatic' or the 'integrated' might be better

Here in Europe, most coffee machine types are this kind, and we usually call them "automatic" machines, having the integrated grinder to be able to use the whole beans

A coffeemaker is a kitchen appliance used to brew coffee without having to boil water in a separate container. While there are many different types of coffeemaker using a number of different brewing principles, in the most common devices, coffee grounds are placed in a paper or metal filter inside a funnel, which is set over a glass or ceramic coffee pot. Cold water is poured into a separate chamber, which is then heated up to the boiling point, and directed into the funnel. This is also called automatic drip-brew;
A drip coffee maker can also be referred to as a dripolator. It works by admitting water from a reservoir into a tube in the base of the coffeemaker, where a heating element partially boils the water. Steam bubbles force the remaining liquid through a riser tube, over a spreader plate, and onto the coffee grounds. The coffee passes through a filter and drips down into the carafe. A one-way valve in the tubing prevents water from backflowing into the reservoir.[1];
A number of different machines used to automate these methods were around until the mid-20th century. In 1972, the first automatic drip-brew coffeemaker for home use, Mr. Coffee, was introduced (Bunn had come out with an automatic drip-brew machine for commercial use in 1963). It combined aspects of both the drip-brew process and the percolating process with the added feature of heating up the water using an electric element in a separate chamber. Since that time, the number, style, and size of these appliances have increased dramatically;

Could this be a possibility here?

Bean to cup coffee machines are sometimes referred to as automatic coffee makers. These machines use whole fresh coffee beans rather than ground coffee.
