Description

[Detailed description of the invention] By introducing superheated steam, fluids such as milk can be heated and/or emulsified at the same time. equipment The invention provides at least one steam ejection nozzle at its free end connected to the steam generation means. A fluid such as milk is produced by introducing superheated steam through a steam pipe that grows the milk. It relates to a device that foams and/or emulsifies at the same time as heating.

This type of equipment is equipped with a steam generation means such as a steam boiler, and extracts superheated steam. Equipment for coffee makers, espresso makers, tea makers, etc., including additional equipment for used for

The use of superheated steam is for drinks such as coffee, tea, milk, cocoa, etc., including soups. and other foods and liquids.Special cooking vessels are suitable for this purpose. Not necessary for the target; materials include tableware such as cups, drinking glasses, and plates. It may also be heated directly within the container.

However, a currently very popular preparation is made from warm milk froth and espresso. It is a mixed drink known as ``Cubcage.'' Addition of milk and steam It gets heated. This is done by frothing the milk, steaming it, and possibly adding air. The purpose is to emulsify. The superheated steam is directed into the still flowing milk, so It is emulsified to a gaseous state. As this is done, the superheated steam superheats the milk. , coagulate the milk and emulsify it as finely as possible (as a result, it is relatively stable and stable). This should combine to form a defined foam.

According to current technology, superheated steam passes through a steam nozzle into a container with cold milk. Attempts have been made to inject In this process, the user must Insert the steam nozzle into the milk and stir it to achieve the right flow and amount. It is necessary to This is to prevent milk from splashing and to prevent hot steam from being released into the surrounding area. It takes a lot of experience to make it look like this.

Devices intended to facilitate this process are known. For example, West German patent no. No. 3538041A1 has a steam release nozzle that creates a vacuum where additional fresh air should be breathed. Discloses a configuration surrounded by a chamber. Furthermore, West German Patent No. 1157750B1 The rotary motion is achieved by passing superheated steam through a spirally extending steam duct. 2 shows a device to be similarly installed downstream of a steam discharge nozzle adapted to be constructed.

A further similar arrangement is known from EP 287906A2.

According to the invention, the one or more steam emitting nozzles are one or more steam emitting nozzles. cooperating with at least one member rotationally driven by superheated steam discharged from the This objective is achieved with a device of the type mentioned above.

The superheated steam discharged from the steam discharge nozzle at relatively high pressure causes the steam discharge nozzle to The cooperating members are rotated at high speed. This quickly emulsifies vapor, air and liquid to be processed as such. The result is a particularly creamy texture with a high air content. Stable milk foam can be easily obtained. Milk froth resembles the consistency of whipped cream achieve the desired concentration. This is the m! of "Cubcage" and similar beverages. ideal for 1 Provide status. In the apparatus of the present invention, the liquid to be treated is mechanically and physically This result is achieved by being simultaneously used thermally. Mechanical for milk - By physical action (i.e. rotational movement), e.g. milk components, especially fats and Proteins are broken down into the smallest particles. Stirring process and subtle introduction of steam and air In combination, the emulsification process proceeds particularly quickly and, with good mixing, produces very stable results. You can get results.

However, it is not only in milk frothing that the arrangement of the present invention yields good results. times The transfer material may contain cocoa, instant coffee, or instant soup, including instant soup. For mixing, blending, emulsifying, foaming, etc. other hot beverages such as instant tea. It is effective.
