Description

The invention relates to an arrangement to warm up of flowable media, especially sauces, beverages or similar

Such media in general heated by means of an electric, gas or microwave oven. at Using a microwave oven gives rise to the problem that the medium is not during the heating stirred at the same time can be. The simultaneity of heat input and stirring is indispensable when preparing the media mentioned above.

Warming up with a conventional gas or electric cookers with the help of a saucepan, that the heat input does not occur evenly in the medium, but the areas near the edge are warmed more.

Some dishes, such as B. hollandaise sauce, must be very gently and evenly heated are going to succeed. If a certain one occurs during the heating process Temperature value is exceeded, can lead to unwanted decomposition processes in the medium make further processing and, if necessary, tasting impossible.

In the known method of heating by means of a pot must therefore during the supply of heat the medium is constantly kept in motion by the bottom of the pot, local overheating near the ground to prevent. In addition, the intensity of the heat supply must be selected so that the temperature of the contact surface does not exceed the critical value.

The heat is therefore supplied a low temperature level. When using the conventional So method must be over a longer one Period under constant stir the heat be introduced to gently heat a sensitive medium to enable. This requires a high degree of skill and attention from the actor and time expenditure.

State of the art

It is commonly known as flowable food or other media to heat by steam injection. With this form of heat input water vapor is directly introduced into the medium, which condenses in it. While The process of condensation becomes the energy contained in the steam released to the surrounding medium, and the medium heats up. This process is used to prepare milk foam for cafes, etc. sufficient known.

For the preparation of media, which is a complicated preparation method require, e.g. B. sauces, it is particularly advantageous to introduce the vaporous heat by means of a stirring device to homogenize. This can be done by moving the steam injector the user are enforced. It’s easier and more effective to use a combined steam injector and stirrer, where the steam is mixed with the medium by, for example, a mixing wheel is mixed. This gives the steam its condensation energy evenly, and the medium is heated quickly and gently.

In PCT application WO 90/10411 described such a device. The steam is supplied here by a hand blender-like device, in the lower part in the immediate vicinity of the steam outlet points a turbine wheel is attached. This turbine wheel is designed in this way and positioned that it is driven by the escaping steam.

The steam drive of the mixing wheel proves to be this construction is disadvantageous because of the rotation of the mixing wheel in viscous or inhomogeneous media can not be ensured, and it to Blocking of the mixing wheel can come. To work around this problem would it be possible a machine to design that both heat and by steam injection can homogenize mechanically.

A large number of devices are known and widespread, which mix, homogenize and are very compact and ergonomically designed. The most common type of such devices are the hand blenders, which are all constructed in the same way. In 1 such a device is shown schematically. The hand blender 10 consists of an upper handle 12 , a lower mixing section 14 and the cylindrical middle part 16 , In the upper part 12 is the electric drive motor, the electrics, the switch 18 and the power cord 20 with the power plug 22 appropriate. The lower part 14 consists of a bell-like mixing hood 24 under which the mixing wheel 26 is rotatably located on an axis. The middle part 16 includes the connecting shaft, which is the rotation from the electric motor to the mixing wheel 26 transfers.

These devices are very common and the need for new acquisitions is therefore largely covered. A Redesign of an integrated hand blender variant that also heat by steam injection can, would hence bad conditions for find the market entry.
