Abstract:
1. A method for the preparation of a beverage by mixing water and at least one powdered soluble product to form a mixture in a mixing chamber having a rotor located inside the mixing chamber or externally to the mixing chamber and dispensing the mixture to a final container, characterized by comprising the following steps: preparing and dispensing to said final container a first portion of beverage by first mixing water or other liquid with a first powdered soluble product, substantially preventing incorporation of air into the water or other liquid by carrying out the first mixing throughout the preparing in an absence of mechanical stirring or with the rotor rotating at a low rotor speed of less than 500 rpm so as to form a first layer of beverage that has an absence of incorporated air; preparing and dispensing a second portion of beverage by second mixing water or other liquid with a second soluble powdered product, incorporating air into the water or other liquid by carrying out the second mixing in a presence of mechanical stirring so as to form a second layer of beverage with a density lower than a density of the first layer due to a presence of the air incorporated into the second layer of the beverage and to an absence of incorporated air in the first layer; dispensing further portions of beverage to the final container, wherein the presence of the mechanical stirring is carried out at a high rotor speed that produces a quantity of froth or emulsion, the low rotor speed improving dissolving without creating the quantity of the froth produced when the rotor is rotated at the high rotor speed.
