Abstract

The aim of the invention is to provide a brew pot which facilitates production of a single-vessel brewing machine with two outer filter elements and an outer heating unit. To this end, a bottomless middle part (1) is linked with two hollow lids (2, 3) via gaskets and bent-lever ring closures (5). Since there are no filter elements located on the bottom that stop the supply of heat, the brew pot can be heated from outside via the hollow lids (2, 3). At the end of a partial brewing process a filter disk is inserted into the tension spring (6) in the upper hollow lid and is pushed down to the lower hollow lid and into the tension springs (6) together with the material to be filtered. By turning the brew pot upside down the filled hollow lid is brought to the top.
Once it has been removed and cleaned, it can be reapplied together with the stirring apparatus and measuring devices to start the second partial brewing process. Due to its design and its simple operability the brew pot is particularly useful for home hobby brewers since on the basis of said pot an inexpensive machine can be put on the market.

Description

r 9 t Brew Pot At the moment, very complex t>eer brewing apparatus are offered to the lay public. In the publications DE 44 40 600 Cl, DE 195 24 783 C1, DE 195 03 244 A1 and DE 197 03 076 Cl are described sink>,le vessel apparatus which already substantially simplify the self-brewing.
Because of interior filter units lying on the bottom, all these apparatus are heated directly in the container.
The task forming the basis o:E the Patent Application is to develop a brewing container which, for good servicing, possesses two outside-lying filter units and is heatable from the outside and is usable as single-container brewing apparatus.
This task is solved in that a bottomless middle part (10) is connected with two hollow lids (13a; 13b) by bent-lever ring closures (14). One hollow lid (13a) is provided in the course of the process for the reception of the wort filter material, the other (13b) for the reception of the mash filter material. Because of the differing amounts, the hollow lids also have different Heights. Since the brewing container, after insertion of a filter disc between the tension springs (17) of the upper hollow lid and after ending of the filter procedure (lowering of the filter disc to between the tension springs (17) of the lower hollow lid), must be turned, on the hollow lids (13a., 13b) and on the double shell (11) are applied hand ,grips (19) for a manual and two pivots (12) for a mechanical turning (in the case of larger volumes). After turning of the container through 180°, the hollow lids (13a, 13b) containing the filtered material can be removed from the bottomless middle part (10) after rernoval of the bent-lever ring closure (14).
After emptying of the mash filter material, cleaning and renewed placing of the stirrer and of the measurement sensor on the hollow lid (13b), the second partial brewing process, the wort brewing, can be carried out. At the end of the process, the second ffiltration is carried out with the hollow lid (13a).
Alternatively to or assisting the double shell, the hollow lids (13a, 13b) with the intermediate bottoms (26, 27), the pipes (30), the sealing sleeves (28) and the intermediate sealing ring can be used as cooling unit.
Im the second embodiment, the hollow lids (13d, 13e) are fixed process-dependently successively only on the~'rniddle part (10). The reception for stirrer, filter axis and measurement sensor are fixed on the flat lid (13c) which upwardly closes off the: middle part (10).
In the hollow lids (13d, 13e) are present, at the position of the tension springs (17), beads (25) in the sheet metal body in which, after pressing down (per spindle or lifting cylinder), the f.-'ilter discs are f ixe d .

Figure l shows the brew pot consisting of the bottomless middle part (10) and the two hollow lids (13a, 13b). The intersecting points are provided with sealings (18) and are held together with bent-lever ring closures (14). The bottomless rniddle part (10) has a double shell (11) for cooling on which are attached two pivots (12) and four hand grips (19) for rotatability. The hollow lids (13a, 13b) also have hand grips (19). Furtherrnore, they have a stirrer and filter receiver (15) with fastenings (20) and a measurement sensor receiver (16) with fastening (21).
The tension springs (17) have the task of taking up a filter disc before beginning of the filter procedure in the upper and after the filter procedure-in the lower hollow lid. The stirrer is fixed in the stirrer bracket receiver (31).
Like Figure 1, Figure 2 shows the bottomless middle part (10) with the hollow lid (13d) for the reception of mash filter material. In this embodiment, the receivers for the stirrer (31), filter axis (15) and measurernent sensor (16) are no longer built into the hollow lids (13d, 13e) but rather only in the flat lid (13c).
Instead of the tension springs (17), in the hollow lids (13d, 13e) are provided beads (25) for the securing of the pressed-down filter disc.
Like Figure 1, Figure 3 shows the three main elements, bottomless middle part (10) and the two hollow lids (13a, 13b). The function of t:he double shell (11) from Figure 1 is here undertaken by the hollow lids (13a, 13b), together with the intermediate bottoms (26, 27).
On the pipe intermediate bott:orn (26) are securely applied pipes (30). These pipes are pushed into the sealing sleeves (28) on the sleeve intermediate bottom (26). The sealing rings (29) seal off against the middle part (10). From the water inlet (22), the water flows through the hollow body (13b) and the pipes (30) into the hollow body (13a) and again emerges from the water outlet (23).
For the putting in of the intermediate bottoms, the container must be turned twice., After removal of the upper hollow lid, the pipe intermediate bottom (26) with the pipes (30) is inserted below and braced with the hollow lid on the bottomless middle part (10). The brew pot is then turned. Thereafter, the upper hollow lid is removed and the sleeve in ermediatc~ bottom (27) pushed over the pipes (30). Finally, the upper hollow lid, sleeve intermediate bottom and middle part are braced.
Figure 4 shows the course of brewing. More than 2 hollow lids can also be used. In this case, the hollow lids have different individual parts and constructional groups corresponding to predetermined process sections.
Like Figure 4, Figure 5 shows the course of brewing. There are here used the hollow lids (13d, 13e) b and the flat lid (13c) described in Figure 2. The flat lid (13c) carries all receiver parts for stirrer, filter axis and vneasurement sensor (31, 15, 16). The hollow lids (13d, 13e) are no longer provided with receiver parts, only a bead (25) is incorporated for the securing of the pressed-down filter disc. The hollow lids (13d, 13e) are here only used as bottoms of the middle part (10). The flat lid (13c) is always applied above on the middle part (10). As shown, for the hollow lid removal from outside in each process step, the container is turned through 180°.
