Automatic device for heating and frothing a liquid, in particular milk

Abstract

An automatic device for heating and frothing a liquid, in particular milk, comprises a container (1) for the liquid, inside which a first tube (6) for introducing pressurised steam into the liquid is removably mounted. The first tube (6) has an inlet in correspondence of the bottom of the container (1), for receiving steam from a duct located within a support base (3) of the container (1), and is secured, for at least part of its length, to a second tube (7) for introducing air into the liquid.

Description

technical field [0001] The invention relates to an automatic device for heating and frothing liquids, especially milk. [0002] Preferably, the present invention is applied in a steam pressurized coffee machine for use in bars for producing frothed hot milk for use in the preparation of cappuccino, the following description will be directed to such a preferred application to describe. Background technique [0003] It is known that in order to produce milk froth from a coffee maker, the operator uses a container into which he pours a certain amount of milk; he then introduces steam into the milk through a nozzle while stirring the container so that the A certain vortex is created in the milk and introduces into it the ambient air which is necessary for frothing. [0004] The amount and character of the foam produced depends on the shape of the stirred milk and the introduced steam, and therefore on the sensitivity and skill of each operator. Thus, the characteristics of th...

Problems solved by technology

Such a solution requires, for correct operation, a chamber for mixing the air and vapor before it is introduced into the liquid, which makes the structure even more complex

Furthermore, it still fails to address the hygienic aspects
