Description

Process for making brewed coffee Description: Subject The invention is a process for the production of brewed coffee, in which without a sieve and with the help of centrifugal force the separation of the non-releasable kaff @@ components from the coffee drink.

In the known method, the coffee is filtered through filtering separated from the non-detachable kaff @@ components. After filtering are located the non-detachable coff @@ components are on the filter that contains coff @@ drink in the respective collecting vessel. The filter must be cleaned before a new air pressure is applied will. In the case of disposable filters (mostly paper filters), these must be replaced.

The disadvantages of this method are known; In the case of filter sieves, the seal setting the filter openings with coffee wax and the finest coffee particles, and subsequently either cleaning processes with more or less aggressive cleaning agents or the acceptance of longer lead times, which would make the automatic brewing process hinder.

With paper filters, the relatively high operating costs.

The invention described below enables the separation of the non-releasable Kaff @@ components of Kaff @@ beverage without filter, and thus switches the aforementioned Disadvantages.

The attached drawings illustrate how the new procedure.

Kaff @@ flour and brewing water (Fig. 1/1) are poured into the brewing vessel (Fig. 1/2) and remain in it as a kaff @@ flour-brewing water mixture (Fig. 1/1) for the duration of the desired brewing time.

With the bottom valve closed (Fig. 1/3) and after the brewing time has elapsed the brewing vessel (Fig. 1/2) is set in a rotating motion. With increasing Speed, the level of the kaff @@ flour - brewing water mixture is shifted by the Centrifugal force from the horizontal to the vertical position. The easily detachable kaff @@ components are pressed against the wall of the brewing vessel by centrifugal force (Fig. 2/4). Likewise in a vertical position above it is the coffee @@ drink (Fig.

2/3).

The ribs (Fig. 1,2,3 / 10) in the brewing vessel (Fig. 1,2,3 / 2) cause a necessarily the same outlet speed of the brewing vessel (Fig. 1, 2, 3/2) and the Coffee beverage (Fig. 2.3 / 5).

If you now reduce the speed of the brewing vessel (Fig. 1, 2, 3/2) and at the same time opens the bottom valve (Fig. 2/3), then the coffee-based beverage flows out (Fig. 2,3/5) according to the laws of gravity over the funnel (Fig. 2/6) in the Collecting vessel (Fig. 1, 2/7). The non-detachable coffee components (Fig. 2, 3/4) remain due to lack of liquid and the brewing vessel during the discharge (Fig. 1,2,3 / 2) centrifugal force still breathing on the vertical inner wall of the brewing vessel (Fig.

2,3 / 2) stick.

After the discharge funnel (Fig. 1, 2/8) is placed under the bottom valve (Fig. 2/3) of the brewing vessel (Fig. 2/2).

A rotating spray water nozzle (Fig. 1, 2/9) is inserted into the from above The brewing vessel (Fig. 2/2) is retracted. The winding process releases the on the vertical brewing vessel wall adhering non-detachable coffee components (Fig. 2, 3/4) and washes them through the bottom valve (Fig. 2/3) into the discharge funnel (Fig. 2/8).

Claims (5)

Claims 1. A method for the production of brewed coffee, characterized in that that without a filter and with the aid of centrifugal force the separation of the non-detachable Coffee components of coffee beverage are made. 2. A method for the production of brewed coffee according to claim 1. characterized characterized in that 6 ribs (Fig.1,2,3 / 10) are arranged vertically in the brewing vessel (Fig.1,2 / 2) are. These ribs (Fig. 1,2,3 / 10) have the task at the beginning of the brewing vessel rotations Generate turbulence in the coffee flour-brewing water mixture (Fig. 1/1) in order to carry out the extraction to reduce the time and to ensure that when the brewing vessel revolutions run out, that the coffee beverage (Fig. 2,3/5) and the brewing vessel (Fig. 1,2,3 / 2) rotate at the same speed leak. 3. A method for producing brewed coffee according to claims 1. and 2. characterized in that the brewing vessel (Fig.1,2,3 / 2) in rotating motion is added and the non-soluble coffee components (Fig..2,3 / 4) with increasing Rotational speed caused by the centrifugal force on the vertical wall of the brewing vessel are pressed (Fig.2,3 / 4). 4. Process for the production of brewed coffee according to claims 1 to 3. characterized in that when reducing the speed of the brewing vessel (Fig. 2, 3/2) and with simultaneous opening of the bottom valve (Fig. 2/3) the set-free Coffee drink (Fig. 2,3/5) according to the laws of gravity via the funnel (Fig. 2/6) flows into the collecting vessel (Fig. 2/7). 5. A process for the production of brewed coffee according to claims 1. to 4. characterized in that for cleaning the brewing vessel (Fig.1,2,3 / 2) the Funnel (Fig.1,2 / 6) is replaced by the discharge funnel (Fig.1,2 / 8) and one Retaining spray water nozzle (Fig. 1, 2/9) inserted into the brewing vessel (Fig. 1, 2/2) from above will.
