Cartridge receptacle, cartridge system, beverage preparation machine, and method for producing beverage

Abstract

The invention relates to a cartridge system (1) for producing a beverage in a beverage preparation machine, comprising a cartridge (2) that has a reservoir (6) filled with a beverage substance (7), and a cartridge receptacle (10) that can be reversibly connected to the cartridge, the cartridge receptacle (10) comprising a mixing chamber (8) and a cartridge discharge device (34) which causes at least partial transfer of the beverage substance (7) from the reservoir (6) into the mixing chamber (8), the cartridge receptacle (10) comprising a fluid supply (12) which opens into the mixing chamber (8). The invention also relates to the cartridge receptacle (10) of the cartridge system (1), the beverage preparation machine, and the corresponding method for producing a beverage (70).

Description

Background technique [0001] The starting point of the present invention is a cartridge system which can be used in a beverage preparation machine for producing beverages, especially cold drinks, which system has: a cartridge (Kartusche), which has a reservoir filled with beverage substances; a ground-connected cartridge receptacle into which the cartridge can be reversibly inserted; and a cartridge unloading device enabling at least partial transfer of the beverage substance from the reservoir into the mixing chamber. [0002] Such systems are known in principle from the prior art and are used for producing beverages from pre-portioned cartridges. Making a drink with such a system is very convenient for the user, since he only has to insert the cartridge and press the start button. The beverage preparation machine then coordinates its production process fully automatically, ie in particular mixes the beverage substance in a predetermined quantity into the liquid (in particula...

AI Technical Summary

Problems solved by technology

[0005] It has been shown that when water is introduced directly into the receptacle of the filling beverage substance, reverse contamination of the supply cannot be completely prevented, because the receptacle is usually completely filled with the beverage substance and thus occurs in the receptacle when water is introduced. significant pressure rise

This pressure rise in the reservoir and flushing of the reservoir all cause, during and / or later in the beverage making process, very small droplets, particles and / or suspensions of the beverage substance to reach the fluid supply and There it leads to continuous contamination of the beverage preparation machine
