From the JP 03232524 A For example, a stir bar is known that vibrates in a liquid.

From the DE 10 432 86 B is already described in the sound field oscillating plate with openings and thin tongues arranged therein. The vibrating plate is used to disperse fibrous materials, in particular filter mass during beer filtration.

Such Method for mashing in associated Mash vessels are Well known in beer production. It is first in a Mash tun the kibbled Darrmalz and brewing water to one Porridge, d. H. mashed to the mash and then the mixture of malt and water heated in a mash pan, being in the mixture enzymes contain the starch of malt into sugar. Both partial processes can also do this be carried out in a single, heatable mash tun.

Around a fast and thorough Mixture of the shot with water as well as the correct and rapid distribution the heat when mash is heated, the mash tun containers usually comprise a stirrer, z. In the form of a propeller containing the charged medium, d. h., The mixture of malt meal and water in the mashing process stirs. To increase production efficiency and manufacturing costs it is desirable to lower the for needed mashing Reduce time required.

From that Based on the object of the present invention, a mash vessel is available which allows a time-saving mashing.

These Task is solved through the mash pot with the Features of claim 1. Preferred embodiments are subject matter the dependent claims.

Thereby, that at least partially inside the mash vessel a Vibrating element for mechanically generating waves in the filled medium, d. h., in the mixture filled in the mash vessel of malting meal and water, due to vibration of the vibrating element has been applied, surprisingly, according to various attempts by the Applicant that the time period for the mashing process considerably (up to 50%) shortened can be.

Because the filled Medium mechanically stimulated to vibrate, propagate Waves in the filled Medium in the form of shock waves from the Vibrating element, d. H. the vibrating stick be generated in the medium. Surprisingly, this leads to results, as they are z. B with also already tried sound z. B with Ultrasound can not be achieved.

Of the jogging rod is shaking inside the mash vessel and movable and is so controllable that it shaking (in the manner of a concrete vibrator) in the filled Medium can be moved, thus by shaking in the in direct contact with the vibrating stick stationary medium to generate waves mechanically.

Further is a known agitator for stir of the filled Medium present, since the achieved by stirring mixing of the filled malt meal known with the water also increase the speed of the mashing process. this leads to for a better contact of the enzymes to the degradable ingredients, like strength, Egg whites etc.

Of the jogging rod can be dimensioned so that due to its expansion in the Vessel a uniform stimulation of the filled Medium achieved due to its vibration in a larger area of the mash pot can be.

For example in this case, the vibrating bar at least partially extend from the bottom of the mash vessel into the interior of the mash vessel and Z. B. by a periodic up and down movement or a lateral Motion vibrate and efficient in a larger area of the mash pot Generate waves.

Furthermore, the vibrating rod may preferably be designed such that it can generate the waves either continuously or intermittently due to its vibration in the medium. Depending on the used geometry of the mash vessel or the type of filled medium to be mashed has been found that either a continuous or intermittent, z. B. pulsed periodically repeating vibration can be particularly advantageous for an acceleration of the saccharification process.

at an advantageous embodiment is the vibrating bar on or at the agitator appropriate. For example, a vibrating bar perpendicular to the Rotary axis of a propeller of the agitator in the mash vessel arranged be and point from the bottom area into the interior of the vessel, or alternatively also on the wing area be attached to the propeller and with this at the mashing process be turned.

To the Mashing with the mash vessel according to the invention in the filled Medium of malt meal and water during the mashing process at least temporarily with the at least partially mounted inside the mash vessel vibrating bar generated mechanical waves due to the vibration of Rüttelstabes by the Shaking rod shaking in the mash vessel back and forth is moved.

advantageous Embodiments of the method according to the invention are that the vibrating element vibrates continuously or intermittently while of the mashing process, and that at least when the vibrating element vibrates, the filled medium continues through a stirrer agitated becomes.

The Invention leads to a shortening the saccharification time during mashing and have the others above in the description of the mash vessel mentioned advantages.

A advantageous embodiment The present invention will be described below with reference to the attached FIG explained The figure is a schematic view of a mash vessel according to the invention.

The figure shows in a schematic and basic way a cross section through a mash vessel according to the invention 1 dar. The mash vessel 1 is for example a combined mash tun.

Internally 2 of the mash pot 1 is at the bottom of a known per se agitator 3 arranged, the two radially opposite propeller blades 4 comprising, about a vertical axis A by a drive system 5 can be driven in rotation. Although the bottom surface of the mash pot 1 cupped, the soil could alternatively be cone (blunt) shaped.

In the illustrated embodiment, the vessel contains a vibrating bar inside 7 as a vibrating element. This vibrating element is on the axis of the agitator 4 attached and extends along the vertical axis A of the bottom portion of the mash pot 1 out into the interior of the vessel.

The arrangement of the vibrating element is not limited to the illustrated preferred attachment, but it may also be mounted or attached in a different position and orientation, as long as at least a part of the element in the interior of the mash vessel 1 located.

The vibrating element is connected to the drive system 5 connected, that the vibrating element controls so that it z. B. is moved by an unillustrated electromechanical device and thereby the directly in contact with him filled medium 6 is mechanically stimulated to vibrate, ie waves in the medium 6 be generated. Under the filled medium is the einzumaischende mixture of malt and water meant for mashing in the interior 2 of the mash pot 1 is filled.

The vibrating stick 7 and the drive system are exemplarily designed so that the vibrating rod 7 as indicated by the double arrow V, is reciprocated for shaking up and down, although the vibration is not limited to this possibility, but any other direction of vibration, for. B. from right to left and vice versa is also possible.

Furthermore, the jolting movement can be generated not only by a dimensionally stable object such as the illustrated stable Rüttelstab 7 in the medium 6 Alternatively, it would also be conceivable that the shape of a shape-changing object is changed as a vibrating element so that the vibrating change in shape of the element leads to the mechanical generation of waves in the medium. This embodiment does not correspond to the present invention.

The inventive method to mash malt and water in a mash pot will now with the help of the attached Figure to be explained.

The usual procedure according to a einzumaischende mixture of malt and water in the interior 2 the mash tuna pan 1 let this filled medium then by rotation of the propeller blades 4 of the stirring work 3 stirred and mixed around the axis A by driving the control and heated during or after mixing by a heater, not shown.

at a temperature of mostly more than 70 ° C develop in the filled mixture contained enzymes have a special effectiveness and lead to a starch degradation and thus saccharification of the malt.

The inventive method is characterized in that at least temporarily during the mashing process, ie in particular also during the phase of saccharification, the vibrating element, ie the vibrating bar 7 by the control to a vibrating vibration movement inside the mash vessel 1 is stimulated by z. As the vibrating bar, as indicated by the double arrow V, within the medium 6 is moved up and down quickly. In this case, vibration frequencies of about 12,000 vibrations per minute have proven to be particularly advantageous.

Due to the fact that the vibrating element, ie the vibrating rod z. B. periodically inside the medium 6 Shaking and shaking is caused by the direct contact of the medium 6 with this element in a direct way, a mechanical wave excitation in the medium 6 executed.

advantageously, Depending on the specific design of the vessel and the input mixture, the vibrating element, d. H. the vibrating bar either continuously or intermittently, d. H. z. B. pulse, while the saccharification period (s) vibrates.

After this the saccharification process accelerated due to the use of the vibrating bar ends is, the mash, as usual, in a lauter tun, not shown pumped.

It has, as mentioned above, proven that in particular the direct mechanical stimulation of the filled medium 6 by shaking the vibrating stick 7 can lead to an acceleration of the saccharification process, so that this process claimed up to 50% less time relative to the stop time than is the case with conventional mash vessels without vibrating element.

Consequently allows the mash vessel according to the invention, the mashing process to accelerate and thereby the brewing time and the associated costs to diminish.
