Beverage preparation machine with grinding device

摘要

#CMT# #/CMT# The machine has a grinding mill i.e. disk grinding mill, provided with a grinding element i.e. cylindrical grinding ring, rotated during grinding process and another grinding element, and an aperture that is provided to a powder shaft (4). Milled powder is transferred from a grinding device (15) to a brewing unit (5). The grinding device comprises a scraping element, which is moved with respect to a rotatable limiting element and includes a plate surface. The plate surface is arranged such that the powder adhered or located at the limiting element is stripped with the scraping element. #CMT#USE : #/CMT# Beverage-making machine i.e. coffee machine. #CMT#ADVANTAGE : #/CMT# The grinding device comprises the scraping element, which is moved relative to the rotatable limiting element and includes the plate surface that is arranged such that the powder adhered or located at the limiting element is stripped with the scraping element, so that the requested drink is exclusively brewed with freshly ground powder while maintaining compactness of the beverage-making machine and without additional cost for the user, thus ensuring better taste of drink, utilizing the beverage-making machine in a flexible manner, and avoiding blockages within the beverage-making machine, and hence prolonging service life of the beverage-making machine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side sectional view of a beverage-making machine with a grinding device and a brewing unit. 4 : Powder shaft 5 : Brewing unit 8 : Grinding mill motor 11 : Pulse generator 14 : Rotational axis 15 : Grinding device #CMT#POLYMERS : #/CMT# The grinding device and/or the powder shaft is made of anti-static materials e.g. polyoxymethylene copolymer or polypropylene.
