Grinders at Alps Coffee

At Alps Coffee, disc and roller grinders are used for grinding, depending on the type of preparation. While disc grinders are used for espresso grinders and fully automatic machines, roller grinders are the premium class for filter coffee.

The grinding discs of the disc grinders are toothed and lie flat on top of each other. The degree of grinding can be adjusted by regulating the distance between the two discs. Flat grinding discs are primarily used for grinding espresso. The size and material of the grinding discs – from steel to carbide and ceramics – have an influence on the grind obtained and the service life of the grinders.

Roller grinders have a complex roller mechanism. Two grooved rollers rotate slowly and crush the coffee instead of grinding it. This process is particularly gentle and fairly quiet. The rollers usually have different geometries in terms of the size and arrangement of the grooves.
