Cold drink preparation machine, method for preparing beverages therewith and method for cleaning same

Abstract

The invention provides a beverage preparation machine (10) configured for preparing cold beverages from soluble beverage ingredients and water, said machine comprising: - a low temperature generating unit (1) for supplying a cooling fluid, and - at least one beverage preparation unit (2) comprising: a beverage mixing chamber (21) configured for mixing soluble beverage ingredients and hot water to produce a hot beverage, said chamber comprising a mixing impeller, and 20. A heat exchanger unit (22) configured for exchanging heat between the beverage produced by the beverage mixing chamber and the cooling fluid provided by the low temperature generation unit, and a beverage circuit comprising A heat exchanger unit (22) and a beverage mixing chamber (21), said circuit being designed to enable the beverage to circulate in a closed loop between the beverage mixing chamber and the heat exchanger unit, and said circuit comprising A pump (23) for circulating the drink, and a circulation device (31,4) adapted to circulate the drink in a closed loop between the drink mixing chamber and the heat exchanger unit, and a dispensing device (32,4 ), the dispensing device is adapted to be able to dispense beverage from the beverage circuit through the beverage dispensing outlet.

Description

technical field [0001] The present invention relates to beverage preparation machines for preparing cold beverages from soluble beverage powders. Background technique [0002] Many beverages, such as espresso and other coffee beverages, milk beverages, chocolate beverages, are usually prepared by mixing a soluble beverage powder or beverage concentrate with a diluent, usually water. Mixing devices are known for mixing beverage components with diluents for more rapid preparation of such beverages. These devices generally include a mixing chamber into which the beverage components and diluent are fed. A diluent is typically introduced into the upper dissolution chamber so that a vortex of the diluent is created to initiate dissolution of the beverage components. The mixture is then frothed by a whipper, usually in a bottom whipping chamber, to fully reconstitute the beverage and ultimately create foam. The beverage is then discharged from the whipping chamber and dispensed ...

AI Technical Summary

Problems solved by technology

However, dissolving soluble powders with cold diluents in the whipping chamber can be difficult, especially for powders containing powdered sugar and / or fat components

In fact, in the final cold drink the sugar is only partially dissolved, there are lumps of powder, the taste is not optimal due to inefficient reconstitution of the drink or too long whipping to obtain the correct reconstitution
