System, cartridge, beverage preparation unit and method for producing beverage

Abstract

Disclosed is a system for producing a beverage, in particular a cold beverage, comprising a cartridge that has a reservoir filled with a beverage substance, a beverage preparation unit with a cartridge receptacle into which the cartridge can be reversibly inserted, and a cartridge discharge device which causes at least partial transfer of the beverage substance from the reservoir into a mixing chamber; furthermore, the beverage preparation unit comprises a fluid supply which opens into the mixing chamber, or the system includes a movable plunger which is placed inside the reservoir and can betransferred from a starting position into a final position by means of the cartridge discharge device.

Description

Background technique [0001] The starting point of the present invention is a system for producing beverages, especially cold beverages, which has: a box (Kartusche), which has a reservoir filled with beverage substance; and a beverage preparation unit with a box receptacle, which can be reversibly insertable into the cartridge receptacle; and cartridge unloading means effecting 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 unit then coordinates its production process fully automatically, ie in particular mixes the beverage substance in a predetermined quantity into the liquid (in particular cold and carbonated water) and directs it into t...

AI Technical Summary

Problems solved by technology

It has been shown that when water is introduced directly into a reservoir filled with beverage substance, reverse contamination of the supply cannot be completely prevented, since the reservoir is usually completely filled with beverage substance and thus occurs in the reservoir when water is introduced. increased pressure

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 causing constant pollution there
