Description

The The invention relates to a small brewing plant with a pan for mash heating and seasoning, a lauter tun and a heater for the pan, taking the pan over the lauter tun in a housing is arranged and a water inlet and a Würzeablauf has and at the bottom of the pan a closable opening to the lauter tun arranged and a method for heating and / or cooking mash and / or seasoning in a small brewing plant.

The Production of the wort from water, malt and hops is the most laborious step in the course of beer production. After heating the mash in the brewing pan at defined temperatures and below Compliance with certain holding times sugar, dextrins, minerals and proteins released from the malt These substances are then separated from the non-soluble ones Ingredients such as husks and seedlings separately. This process runs in Lautertun whose bottom has a sieve-like perforation and thereby the so-called Marc retains. Subsequently, will the seasoning thus obtained mixed with hops and for Cooked a certain amount of time. The variation of temperature and / or Time programs of said operations provides the basis for the production of different beers.

There in recent years a trend towards the independent production of beer became noticeable for the Beer making, however, certain devices available and technical Prerequisites must be met have to, are already devices and methods for brewing beer with Help from Kleinbrauanlagen become known.

From the DE 295 07 934 U1 For example, there is known an apparatus for producing beer which has an electric cooking plate as a heat source. On the stove plate is a pot, which serves for mash heating and wort boiling. The disadvantage here is that the control of the heating power of a conventional cooking plate is relatively sluggish, making accurate temperature control during mash heating difficult. In addition, heating by means of a hotplate is associated with non-negligible radiation losses.

Also known is a method for heating mash and / or wort with the aid of microwaves from the DE 197 46 437 B4 , Here, the brewing vessel is assigned to an external microwave source, which is either flanged to the brewing vessel or connected via a microwave conductor with this. The disadvantage here is the additional space outside the plant, which is why this arrangement does not seem appropriate for use in a small brewing plant. Another embodiment of the device according to DE 197 46 437 B4 provides the arrangement of the microwave source within the brewing vessel, wherein the inner wall of the brewing vessel acts as a resonator for the microwave radiation. However, in this case the microwaves must be prevented by a grid-like shield from leaving the brewing vessel through existing filling or emptying openings. In addition, the space required within the brewing vessel and the additional cleaning effort after the brewing process has a disadvantageous effect in this embodiment.

The Hopfung the wort after the refining process can be done advantageously by means of a Hopfengebers, what facilitates the exact dosage of the hop.

Advantageous It is when the hop donor a turntable with several filling chambers is, wherein the turntable in its initial position, the pan after Outside covering. This will cause the escape of water vapor and light volatile Connections during the heating / boiling of mash or wort in the environment of the plant avoided. The hop generator is advantageously provided with a motor driven and indicates a control signal in a filling chamber available amount of hops is free. Through the different filling chambers is it possible to prepare several hops. The wort production is through this Hop donors further simplified and can be fast and even for the layman easy to carry out take place, because the exact time of the hop giving by the recipe is specified and can be performed automatically.

advantageously, the water inlet has a controllable valve, whereby the filling of the pan can be easily controlled at the beginning of the brewing process. After this Passing a predetermined amount of water or to a corresponding control signal the valve is automatically closed again.

Furthermore It is advantageous if the pan is a temperature sensor for the measurement the water mash or seasoning temperature is assigned to control the correct temperature control of the mash or wort and, if desired, on time to intervene in the course of the brewing process.

For the measurement the level the pan is assigned to this advantageously a level sensor, the level at any time of water, mash or seasoning in the pan can detect.

Especially It is advantageous if the level sensor via a Blowing device for Air and a pressure measuring device for measuring the occurring Back pressure, depending on level the pan is.

advantageously, is the seasoning process spaced from the bottom of the pan so that during the Cooling the seasoning to the bottom sinking heavier constituents of the wort such as hop grains and protein-tannin compounds when draining the wort remain in the pan.

It also brings There are advantages to it, if at the opening to the lauter tun towards a disc valve is arranged, via which the emptying of the pan in the lauter tun can be regulated. The disc valve is low maintenance and prevents Clogging when draining the mash.

is under the opening to the lauter tun arranged a baffle plate, so is advantageously the formation a Filterberg at the bottom of the lauter tun when draining avoided the mash from the pan. This favors the formation of a homogeneous and loose filter cake at the bottom of the lauter tun and thus a improved filtering of the mash.

moreover it is advantageous if the lauter tun between the bottom of the lauter tun and the pan is associated with a pump, with the help of the wort after the refining process back can be pumped into the pan.

The Pump should be advantageously equipped with an idle protection be to avoid drafting.

Of Furthermore, it is advantageous if the lauter tun can be removed from the housing is to clean the same and the inside of the case too facilitate. Furthermore this facilitates the disposal of remaining after the refining process Spent grain.

It is also advantageous to equip the system with a screen, in particular for displaying physical parameters such as temperature, time and / or level of the pan, which are detected via the respective sensors or to display the progress of the current brewing process. This simplifies monitoring of the brewing process by the plant operator. But the screen is also helpful for programming the brewing system.

Especially advantageous is the assignment of a control system to the order To allow control preferably of the complete brewing process, starting with the entry of the brewing water, the heating of the water over the various heating and rest periods of the mash, the refining process, the pumping of the wort back in the pan, the addition of hops and wort boiling.

the Screen is advantageously associated with a touch panel over which can be changed by the controller controllable sizes.

at a method according to the invention for Heat and / or cooking mash and / or seasoning in a small brewing plant The functions are water supply, heating, hop addition, emptying the pan and / or pumping the wort into the pan after the Läutervorgang programmatically or manually controlled, the progress of the individual process steps and the actual and desired states of the controlled variables temperature, time and level the pan can be displayed on a screen. The operation is thereby also for It is very easy for the layman. He can either largely automatic the system with a given Run program, intervene in finished programs and this change according to need and taste or create new recipes according to your own ideas. The individual program steps are displayed on the screen and are within the permitted range Value ranges changeable.

Advantageous is also the possibility, Create and save new program sequences with the help of the touch panel to be able to.

Further Advantages of the invention are in the following embodiments described. It shows:

1 a sectional view of the small brewing plant and

2 a top view of a hop donor.

1 shows a pan 1 for heating and / or cooking mash and / or cooking wort and an underlying lauter tun 2 , At the beginning of the brewing process, brewing water flows through a water inlet 3 and regulated by a controllable valve 4 in the pan 1 through to a level sensor 5 detected level of the pan 1 is reached. The level sensor 5 consists in this embodiment of an air injection device and an associated pressure measuring device which detects the required air pressure when injected into the water. Since this is dependent on the water level, it can after appropriate calibration of the level of the pan 1 be determined.

Subsequently, the water is passed through a controllable radiant heater 6 to a certain temperature, by means of a temperature sensor 7 is detected, heated. To ensure a uniform heating of the mash and seasoning, are under the bottom of the pan 1 at least one, preferably five radiant heaters 6 appropriate. These consist of heating conductors, which are heated by electrical resistance heating and conditionally given by their construction, the heat radiation directed upwards. A coating 8th the bottom of the pan 1 prevents reflection of the heat radiation and thereby improves the efficiency of the radiant heater 6 , In addition, the coating ensures 8th an improved heat transfer between the bottom of the pan 1 and the medium to be heated, whereby a rapid heating and accurate temperature control of mash and wort can be done, since changes in the heating power of the radiant heater 6 be quickly passed to the medium to be heated. Towards the lauter tun 2 are the radiant heaters 6 preferably through an intermediate floor 9 separated, losses of heat radiation in the direction of Läuterbottichs 2 to minimize.

After adding the malt through a closable opening 10 in the top of the pan 1 is the mash in compliance with certain time and temperature programs and using a stirrer 11 heated, with resulting vapors over one at the top of the pan 1 arranged deduction 12 subtracted from.

Then the mash is opened by opening a disc valve 13 at the bottom of the pan 1 in an insert 14 the lauter tun 2 emptied (so-called main casting), with a homogeneous distribution of the mash on the bottom of the insert 14 through one in the opening between pan 1 and lauter tun 2 built-in baffle plate 15 is reached. Through the baffle plate 15 a cone-shaped mash of mash is avoided, as the mash on the baffle plate 15 impinges and rebounds annular. The mash is thus not unnecessarily compressed and the spent grains are thus easier to separate from the liquid wort.

After closing the disc valve 13 the pan is refilled with a defined amount of water, heated to a certain temperature and then also in the insert 14 the lauter tun 2 emptied.

The wort from the main and Nachguss, located in the lauter tun 2 collects, then by a pump 16 over the wort intake 17 back to the pan 1 pumped and brought to a boil. After adding a defined amount of hops over a hop donor 18 the wort is cooked until the end of the brewing process.

After cooling the wort, this is a Würzeablauf 19 drained into a separate container, not shown. By the spacing of the Würzeablaufs 19 from the bottom of the pan 1 a separation of the wort is ensured by existing heavier components such as hop or protein tannin compounds, which are during the cooling of the wort at the bottom of the pan 1 drop.

All temperature and timing controls are preferably via the controller 20 controlled and are via a touch panel 21 independently influenceable. The basis of the control is the comparison of actual and desired states of all detected variables such as temperature, time or level of the pan 1 , Based on these variables, the individual functions are water supply, heating, adding hops, emptying the pan 1 and / or pumping the wort into the pan 1 controlled after the refining according to the specifications of predetermined programs, so that the user does not have to intervene in the brewing process and a nearly automatic wort production is possible. In addition, however, is also a manual control of the individual process steps on the touch panel 21 as well as the addition or independent change of individual program steps possible. Thus, the layman can create their own programs according to different beer recipes and their own ideas after a brief briefing, which can be stored for recall.

According to 2 consists of the hop donor 18 preferably from a rotatably mounted disc 22 , on top of which cylindrical filling chambers 23 are arranged, which are open at the top and bottom. The disc 22 again points below the filling chambers 23 Openings from the diameter of the filling chambers 23 on. The disc 22 located on another, not shown disc of the same diameter, which is mounted on top of the Kleinbrauanlage and an opening 24 with the diameter of the filling chambers 23 having. The upper disc 22 is driven by a motor, not shown, or can be manually or via a signal from the controller 20 or a switch. By turning the disc 22 becomes the first of the filling chambers 23 with the opening 24 the lower disc aligned, causing the hops in the pan 1 arrives. By the arrangement of several filling chambers 23 Several time-shifted hops are possible during the cooking process of the wort and by the controller 20 programmable in advance.
