Abstract

L'objet de la présente invention est de fournir un dispositif de fourniture de boissons à encombrement réduit qui est susceptible de fournir une pluralité de types de café. Dans ce dispositif de fourniture de boissons (100), une unité de commande (50) réalise de façon séquentielle : une opération d'introduction de grains de café consistant à introduire du café moulu qui a été broyé jusqu'à obtenir une taille de particules correspondant au type de café sélectionné par une manipulation de sélection sur un panneau tactile (3) dans un cylindre (311) ; une opération de compression consistant à ajuster un capuchon (37) sur le cylindre (311) et à comprimer le café moulu selon différentes pressions en fonction du type de café sélectionné par la manipulation de sélection ; et une opération d'extraction de café liquide consistant à fournir de l'eau chaude dans le cylindre au moyen d'une pompe à eau chaude à différentes vitesses de fourniture en fonction du type de café sélectionné par la manipulation de sélection et à extraire le café liquide.
