The present invention relates to a preparing device (1) for preparing an aqueous beverage by means of a beverage ingredient. The preparing device (1) comprises: an outflow nozzle (33) for dispensing prepared beverage; a preparation chamber (13, 16, 14) for at least partially preparing the beverage; a supply (12) line ending in the preparation chamber for the supply of water to the preparation chamber; an ingredient-dispensing system (7) for delivering the beverage ingredient to the preparation chamber; and an outflow path (36, 33) which extends from the preparation chamber to the outflow nozzle. The outflow nozzle (33) and/or the preparation chamber (13, 16, 14) and/or the outflow path (33, 36) are entirely or partly made from a polymer mixture which comprises (a) a self-lubricating, hydrophobic polymer or copolymer having a moisture absorption, determined in accordance with ASTM D 570 at a relative humidity of 50% and a temperature of 23° C., of less than 1% and (b) a homopolymer or a copolymer of a fluorinated ethylene. |
