Description

The invention relates to a kettle for brewing beer, comprising a liquid-flowable and maltable container, which is re-removable in the boiler and is provided with a hydraulic pump having a pipe having one end from below into the container and with the other End flows into the boiler, wherein the hydraulic pump pumping the liquid located in the malt tank from the one in the boiler or malt tank emptying end of the pipe to the other end.

Such a boiler is already known, see the DE 101 50 395 ,

A disadvantage of the known construction is the need to make special parts. So a relatively strong bottom plate is required to ensure the seal. The malt tank can not be filled with malt outside during water heating (up to the mashing temperature up to 65 ° C). This exposes the operator to the water of elevated temperature for only a short time with my hands. To work around the problem is mashed at lower temperatures, which is not always desirable and does not correspond to modern brewing protocols. Removal of the malt tank requires disassembly above the heated mash (normally at approx. 78 ° C).

In ascending flow according to the prior art ( DE 101 50 395 ) can not produce a filter bed.

The object of the invention is to avoid the disadvantages and to create a boiler as simple as possible for brewing beer, which is also easy to use.

According to a first alternative, the malting vessel for solving the above problem has an unperforated wall and a non-perforated lid and a perforated bottom, and the malting container has a perforated inlet column in its interior, which is centered in the bottom of the malting container with the tube end of the mouth opening in the malting container the pipeline is releasably connected, such that a liquid circuit can be produced axially from the top of the interior of the malt tank to its perforated bottom. As a result, a filter cake or filter bed of malt grain shells occurring in the mash forms on the bottom. The malt container designed in this way allows this filter bed, which contributes enormously to the clarification of the mash. Professional plants have a lauter tun which has a top-to-bottom flow and contributes significantly to the quality of the mash / beer.

According to another, second alternative, the malting container is provided with a perforated wall, an unperforated lid, and a non - perforated bottom, except for a passage of the tubing, and the malting container has a perforated inlet column in its interior centered in the bottom of the malting container End of the tube in the malt container opening end of the pipe is releasably connected, such that a liquid circuit can be produced radially from the center of the malt tank to its perforated side wall.

Through these measures of boiler construction, the malting container can be made from simple sheets and you do not have to make it from rolled material or use reinforced floor slabs.

The construction can be made with ordinary pots (household goods).

The malt tank can already be filled with malt during water heating up to the mashing temperature (up to 65 ° C). This exposes the operator only for a short time with his hands to the water at elevated temperature. The removal of the malt tank is quick to do and requires no disassembly over the heated mash (usually about 78 ° C). A short turn of up to 60 degrees is enough.

The hydraulic circuit runs from top to bottom and the malt tank is halfway to completely submerged. Thus, oxygen occlusion is avoided.

According to one embodiment of the invention, a coupling, in particular a bayonet coupling is provided as a detachable connection between the inlet column and the associated end of the pipe.

Another alternative is configured such that a sidewall is constructed as a polygon approaching a circular shape.

The boiler is designed so that the malt tank has a protruding into the boiler room handle or handles or lugs.

As mentioned, the coupling is provided with an O-ring seal.

At the bottom of the boiler a heating coil is arranged to heat the mash.

The arrangement has the further advantage that, according to a development of the invention, the coupling can be connected to a flow vortex tube after the mash has cooled, so that the debris accumulates in the middle of the vessel.

The coupling can also serve to connect a pipe leading to a heat exchanger.

The invention will be explained in more detail with reference to exemplary embodiments, which are illustrated in the drawings.

It shows:

2C a similar view as at 1C the second alternative,

3 in an axially sectioned perspective view of the malt container, which is removable by rotation,

1A shows schematically the boiler according to the invention 10 in a first embodiment, the z. B. for brewing beer, comprising a liquid-flowable and fillable with malt and / or hops container 12 in the cauldron 10 is removable and can be used with a hydraulic pump 14 having piping 16 is provided, with its one end 18 from below into the container 12 and with their other end 20 in the cauldron 10 opens, with the hydraulic pump 14 those in the malt tank 12 located liquid 22 one of them in the cauldron 10 or malt container 12 opening end of the pipeline 16 pumping to the other end.

The malt tank 12 has an unperforated wall 24 and a non-perforated lid 26 and a perforated floor 28 on. The malt tank 12 also has in its interior a perforated inlet column 30 on, the middle of the ground 28 of the malt tank 12 with the pipe end 18 the pipeline 20 of the mouth of the muzzle opening of the pipe is releasably connected, such that a liquid circuit axially from the top of the interior of the malt tank 12 to its perforated bottom 28 can be produced, see the arrows 32 , and the level 46 here below the malt tank below the opening 48 at the end of the inlet column 30 lies while he, see reference number 46 in the embodiment of the 2A above the lid 26 of the container 12 lies.

The detachable connection between inlet column 30 and the associated end 18 the pipeline 16 is a coupling, in particular a bayonet coupling 34 intended.

1B shows an embodiment of the boiler 10 in a perspective view of the arrangement, in which it can be seen that the side wall is constructed as a circular shape or as a circular shape approximate 8-sided polygon.

The bending edge 36 belongs to a polygon with 8 corners 36 which represents a good approximation to a circular shape.

The malt container carries a protruding into the boiler room handle or handles or lugs 38 ,

The coupling 34 is provided with an O-ring seal. After cooling the mash in the container 12 the flow vortex tube can be connected via the coupling. Before can be done with a connectable via the clutch heat exchanger, the cooling.

As the flow runs from top to bottom, a filter bed is easier to form, which improves the washing out of the malt and favors the filtering of the mash. The fact that the malt container can be placed under the pressure of the pump from above makes the washing with the filter more efficient.
