Definitions
- the invention relates to a method for producing beer according to the preamble of claim 1.
- the present invention has the object to provide a method for beer production, which allows a simple way to process optimization.
- the liquid may be a liquid which is used to produce the intermediate product or else, e.g. a mixture of which the intermediate is formed.
- chemical, physical and enzymatic processes are significantly influenced by setting a specific pH range and mineralization of the process media.
- metabolic processes of microorganisms e.g. can also be manipulated by voltage and current flow. Ionization is easy and inexpensive to implement. Also, unwanted anions or cations can be removed by targeted ionization.
- the production of the wort begins in the brewing process, the wort produced is then fermented into beer.
- Diaphragm electrolysis leads to an ion shift and local accumulation of differently charged particles. Part of the liquid on one side of the membrane assumes an acidic character, whereas the other part becomes basic.
- the accumulation of certain charged particles in a region of the device as well as the change in pH can be used selectively to optimize processes for the production of intermediates in beer production, without having to add foreign substances.
- the electrolysis can be selectively influenced and thus, for example specifically the pH value can be adjusted.
- a corresponding apparatus for diaphragm electrolysis can be provided inexpensively and simply and retrofitted into existing systems.
- an acidic and a basic fraction are produced, whereby one of the fractions can be used to produce the intermediate product.
- the basic fraction is used for this intermediate process.
- the other fraction is then discarded either and / or for another, i.
- the acid fraction can then be added again, which on the one hand leads to a pH balance and on the other hand ensures that ions that have permeated into the acidic region through the membrane, be returned to the subsequent product and not lost.
- Excess acidic / alkaline fractions may e.g. used for cleaning purposes.
- the device for electrolysis in particular diaphragm electrolysis thus has two areas separated by a membrane, wherein the basic fraction is produced in the first region and the acidic fraction in the second region.
- a liquid to be ionized can therefore be conducted into the first and in the second region and ionized and discharged again from the respective areas.
- the ionization can be carried out in batch mode or continuously.
- a liquid of a first process may be passed through one of the two regions and liquid or water of another process may be passed through the other region of the device, whereby the liquid of another process may be, for example, liquid of an earlier or later production phase.
- cocurrent or countercurrent water may be passed through the second region to produce acidic water and hoped wort may be passed through the first region to produce basic, hopped wort.
- the first and / or second area is influenced by targeted fumigation.
- a gas for example air or ozone
- the liquid is gassed before ionization.
- the liquid or the liquids can circulate through the first and / or second region in each case.
- the liquid can be stored in a container (eg also reaction / process container) or buffer and circulate batchwise or continuously through the respective region of the device for diaphragm electrolysis and the container, so that an effective mineral shift or pH value shift is possible.
- liquid to be ionized is passed through one of the two areas, then a certain reaction path (for example, piping system) passes through and is then supplied to the other area of the same or another device.
- a certain reaction path for example, piping system
- a predetermined pH and / or redox potential is set by the ionization.
- the pH value can be adjusted by selective adjustment of the ionization parameters, such as, for example, potential difference between the electrodes or current intensity, residence time of the liquid in the device, size of the contact surface of the electrodes, temperature of the liquid, etc., preferably by continuous pH Value measurement and / or by measuring the redox potential can be controlled.
- Adjustment of the pH (or the redox potential) by ionization is here understood to mean at least partial alteration or adjustment by ionization, that is to say that the pH may additionally be stabilized by other measures, e.g. Addition of certain pH-changing substances, can be influenced.
- a process for producing an intermediate product may, for example, be a process from the following group: hop isomerization, hop aroma leaching, production of a kieselguhr solution for precoat filtration, production of mash, lautering, tipping, Production of the wort, in particular wort acidification and wort boiling, acidification production, bacteriocidal production (eg nisin), acidification of microorganisms, in particular yeast.
- the invention can be used very particularly advantageously as a process for hop isomerization.
- the intermediate is then the isomerized hop / liquid mixture added to the wort.
- the isomerization of the hop is preferably carried out in a basic medium, in particular in a pH range of 8 to 14, preferably 9 to 14 wherein the pH adjustment is carried out by ionization of a fluid involved.
- the pH of the wort is normally in the range of 5 and can therefore be effectively increased by ionization to pH> 5. It may be advantageous if unwanted substances, for example iron ions or manganese ions, are removed prior to ionization.
- Hop isomerization can either be carried out by ionizing a liquid, in particular wort or water, and adding hops to the basic fraction of the ionized liquid. But it is also possible that hops of a liquid, in particular wort or water is added and the mixture is then ionized continuously or batchwise, such that a basic pH is generated. Then it is advantageous to first pass the mixture through a filter, also by e.g. Blocking of the membranes to avoid.
- the hop isomerization then takes place in a separate isomerization vessel, wherein the isomerization is preferably carried out in a temperature range of 20 to 100 ° C, in particular 60 to 100 ° C and the mixture is preferably homogenized, for example by stirring, by the use of dispersing, circulating or ultrasonic or mechanical vibrating units.
- a controllable heating device can be provided.
- at least parts of the hop-liquid mixture (or one of the zu ionizing liquid) are heated in front of the isomerization vessel.
- the mixture may be added to the wort kettle for cooking the wort and / or after cooking. (Cooking can also be understood to mean keeping hot just below the boiling point).
- An acidic fluid fraction produced during the ionization can be metered into the basic liquid-hop mixture after the isomerization, in order to lower the pH again, so that aroma leaching can be promoted.
- the hops can first be treated in the basic liquid fraction, so that an isomerization can be promoted and at the same time a reduction of nitrates takes place, before subsequently an acidic treatment for leaching of the flavor can be carried out. This is a very advantageous process.
- the hops and / or part of the hops are treated in an acidic environment to promote flavor leaching, the respective environments being generated by the ionization of at least a portion of the mixture as previously described.
- desired aroma complex can be solved.
- These intermediates are preferably added at the end of wort boiling, i. e.g. in the whirlpool (so-called “late hopping”), used during the transfer and / or in the cold process area (so-called “dry hopping”), so that the volatile substances do not evaporate, metabolise and / or get lost due to buildup.
- the ionization technology can also be used purposefully to achieve e.g. specifically to remove substances contained in hops such as nitrates, pesticides and / or microbes or to reduce their contents.
- a withdrawal of such substances by means of ionization technology can be carried out in advance, before then the process of isomerization and / or flavor leaching, for example at a higher or lower temperature is made.
- the fluid by then transferring the undesired matter may optionally be discarded or otherwise utilized (e.g., for purification).
- the process for producing an intermediate sample In particular, diatomaceous earth is introduced into liquid and then ionized, the pH being adjusted within a range of 2 to 7.
- the intermediate is the kieselguhr dissolved in liquid.
- This method has the advantage that it can be prevented that unwanted substances such as iron, and / or arsenic are introduced into the product by the kieselgureintrag.
- the electrodialysis process achieves ion shifts such that unwanted ions, for example the aforementioned ions, can be effectively removed from the diatomaceous earth solution. This also allows the use of previously classified as "inferior" Guren.

- the intermediate here is the isomerized hop / liquid mixture.
- the hops were added directly to the wort kettle such that in the boiling wort, a rearrangement takes place in the structure, in particular the alpha, beta and other hop acids, which is referred to as isomerization.
- the resulting iso-compounds are much more soluble than e.g. the alpha acids from which they originated.
- the isomerization of the alpha acids during the cooking is by no means complete.
- the pH should preferably be adjusted within a range of preferably from 8.0 to 14. If the isomerization is carried out at this pH, the yield of the hop can be increased by up to 20%, which leads to substantial savings in the beer production.

- the hop / liquid mixture can also be added to any other process point in beer processing and / or the acid fraction A can also be used for other processes, for example also for cleaning purposes.
- Such a process also has the advantage that the content of certain substances can be adjusted.
- pesticide, iron and / or nitrate contents can be actively and selectively reduced according to the invention.
- FIGS. 6a and 6b are also suitable for allowing (hop) flavor leaching.

- process step "dry hopping” instead of "wort kettle”.
- Fig. 7 shows a further embodiment of the process according to the invention for hop isomerization, in which case e.g. first the liquid, e.g. Wort or water, is ionised by dissolving the liquid e.g. both areas of a device for diaphragm electrolysis 9 is supplied, whereby a basic and acidic fraction is generated. As in the previous embodiments, a certain desired setpoint pH of the basic fraction B is set.

- the ratio of hop to liquid fraction is preferably 1:10 to 1: 100.
- the isomerization vessel 7 is optionally heatable and has, for example, a volume of 1000 liters, preferably in a temperature range of 20 to 100 ° C, more preferably 60 ° to 100 ° C.
- the container has, for example, a stirring device 8.
- the hop / liquid mixture is pumped through the first area 1 of the diaphragm electrolysis device 9 with the aid of a pump 10 Pumped through or sucked through.
- the optimum values for the current intensity or potential difference for a specific device 9 were determined empirically beforehand. The ionization takes place until a pH in an area for isomerization of ideally 8 to 14 and for flavor leaching of less than 5, preferably 2 to 4 sets.
- the isomerization / flavor leaching process can be optimized.
- the hop / liquid mixture will continue to be retained in the container 7 until the desired reactions have occurred. This can be detected, for example, by measuring the degree of isomerization.
- the process duration may be determined empirically in a calibration process.
- a pump for example, the pump 10 is adjustable, for example, frequency controlled.
- a controllable pump allows the volumetric flow to be freely selected, so that the speed of the ionization can be influenced / controlled.
- this can also be accomplished by means of a control valve and / or a throttle or the like.

- an acidic / basic fraction A / B is generated, whereby this liquid also circulates through the second region.
- This acidic / basic fraction can, for example, be stored in a buffer memory after completion of the ionization and either, as described in connection with FIG. 6b, fed to another process or the wort.
- Fig. 4 has been described in connection with an external device for diaphragm electrolysis 9. However, it may just as well be a corresponding device for membrane diaphragm electrolysis integrated in the isomerization vessel 7, such that the container in which the intermediate product (hop / liquid mixture) is treated, is directly connected to the membrane 5 and / or the container through a membrane is subdivided into separate regions or reaction spaces 1, 2.
- the hop isomerization is carried out by circulation through a chamber 1, but it is also a hop isomerization by circulation through both chambers or areas possible.
- the intermediate is an isomerized hop / liquid mixture.
- the hop / liquid mixture can also be guided over the membrane or the diaphragm in such a way that it is offset in time from the positively and negatively charged electrodes 6a, b is passed, as shown in particular in FIG. 5.
- liquid eg hot wort or hot water
- the hop / liquid mixture is first mixed with hops and passed past the negatively charged electrode 6a through the first region 1, so that the mixture temporarily assumes a basic character, which favors the desired isomerization reaction.
- the transfer into a reaction section 3, for example a correspondingly long line or else a vessel, allows the time-dependent course of the isomerization and improves the mixing before a neutralization takes place in the second area 2 of the device for diaphragm electrolysis.
- the reaction section 3 can likewise be heated, so that a temperature of 20 to 100 ° C. of the mixture can be maintained.
- the ionization takes place in such a way that adjusts the aforementioned pH range.
- the mixture leaving zone 2 it is also possible for the mixture leaving zone 2 to be returned to zone 1 to achieve complete isomerization.
- the mixture can be passed through the 1st and 2nd area of a device or else through the 1st and 2nd area of 2 different devices, for example, if several devices are arranged in parallel or behind one another.
- the polarity of the electrodes can be reversed in this case too, so that first an acidic reaction and basic neutralization takes place.
- the basic environment is ideal for optimizing the isomerization, that is to say favoring the bitter substance transformation.
- an acidic environment is more suitable for dissolving aromatic components out of vegetable materials.
- the hops or a part of the hop / liquid mixture can be treated in an acidic environment. This reduces the isomerization rate and thus the bitterness, but promotes flavor leaching. Accordingly, products treated in this way are suitable for flavoring, for example the wort to be cooked and / or for the so-called cold range of the brewery. In this case, a cold process management may be advantageous (so-called dry-hopping / hop-hopping).
- flavor leaching may also be used, for example, at colder temperatures at e.g. -3 to +20 ° C, wherein one of the intermediates may optionally be water and / or beer.
- the hop / liquid mixture can be treated first after ionization in a basic medium, as explained in connection with the previous embodiments, and then treated by ionization or addition of acidic medium in an acidic medium before it is fed to the wort kettle, for example , but it is also possible to treat the hop / liquid mixture only in an acidic environment and then in basic or treated in an acidic medium mixture of the wort, or a downstream intermediate product such as beer is added.
- An advantageous embodiment according to the present invention is also a process for producing diatomaceous earth solution for precoat filtration.
- the intermediate is here for precoat filtration in liquid dissolved diatomaceous earth.
- Diatomaceous earth is usually supplied in powder form and contacted with liquid in solution tanks to allow for solution and subsequent soak in the precoat filters for beer filtration.
- ionization takes place during the treatment of the kieselguhr solution.
- diatomaceous earth powder is introduced into liquid and then ionized with a diaphragm electrolysis apparatus until a predetermined pH in the range of 2 to 4 on the diatomaceous earth side is established.
- the diaphragm electrolysis device 9 can be integrated, for example, in the dissolving / mixing vessel, such that the first and second regions described above and the electrodes are in the mixing vessel, or else the mixture can be conducted from the vessel into a separate device 9 for diaphragm electrolysis.
- the diatomaceous earth-water mixture may first be passed through an area (either the 1st or 2nd area) of the diaphragm electrolysis apparatus and subsequently through the other area (the 2nd or 1st area ) of a second device 9, wherein, for example in the other area of a device another liquid, such as another process liquid or water, is performed. This ensures that both unwanted cations and anions can be removed.
- Fluid ionizing for mashing When mashing, first the crushed (crushed) grain (eg malt) is mixed with water (brewing water). Because certain enzymatic degradation processes are sought, and different enzymes have different temperature and pH value-dependentmannsoptima ma, there is a gradual increase in temperature of the mixture.
- crushed grain eg malt
- water brewing water
- brewing water can be treated by electrodialysis primarily so that its character is initially more basic, i. is in the range of preferably 8 to 12, whereby the enzymes could work better.
- the acid brewing water fraction can then be used for exact pH adjustment, or alternatively for other processes.
- water for infusion In order to adequately leach the grains, that is to say to wash the sugar out of the husks, during the refining step, water for infusion is added. This water usually has brewing water quality. Often the tempering water is tempered, that is hot, with modern methods for energy reasons also provide for the use of cold water.
- a setting of the swan-water pH to eg 2 to 4 and / or 9 to 14 leads to a better spent grain leaching and thus brewhouse yield.
- the contact risk of degradation of the spent grains can be reduced by a corresponding degree of acidity (eg when using acid catching waters).
- electrostatic interactions determine settling behavior, filter bed formation and separation behavior during filtration.
- partial charging of the liquid can be used to target particles and optimize the process, e.g. the pH of the swelling water is adjusted to preferably 2 to 4 and / or 9 to 14 by ionization.
- lactic acid may be added to adjust the pH of the wort.
- this process step takes place at the end of the cooking process.
- Intra-process lactic acid production is relatively expensive and requires special, costly reactors and plant components.
- a dosage of technical acid does not comply with purity requirements and can lead to a reduction in quality and logistical problems.
- the acidic fraction of previously ionized liquids can be used to achieve a desired acidity. This includes the possibility of removing a portion of the wort after refining, separating it by electrodialysis into an acidic and basic fraction and deliberately recombining the fractions.
- the basic fraction can be used for mashing and / or hop leaching
- the acidic wort fraction can be used for example in wort acidification (for example at the end of the cooking).
- the pH of the acidic fraction is e.g. in a range of preferably 2 to 4.
- ionizing the wort to a pH of preferably 2 to 4 and / or 9 to 14 before or during the cooking desired processes can be achieved more rapidly and / or at lower temperatures.
- the resulting vapor condensate can be qualitatively upgraded by ionization because, for example, undesirable species such as aroma-active substances can be destroyed, unwanted anions can be removed by passing the condensed vapor vapor through the first region, and cations can be removed by passing the condensate through the second region.
- the lactic acid can also be produced in-house in so-called acidification plants with the help of lactobacilli.
- the lactate, which arises during this process, is considered as a value-giving component, which is awarded a health-promoting effect.
- a constant pH in the lactic acid plant can be maintained in a range of pH preferably 2 to 6, thus making lactate formation more effective and reducing product inhibition.
- a subdivision of the vessels through membranes can be carried out and / or the ionization process can take place independently outside the containers.
- membranes which specifically permit or prevent a permeability of the organisms.
- bactericides such as nisin can also be produced in the brewery by microorganisms.
- the process technology is very similar to that in the production of lactic acid
- this ideological may be neutralized to a certain degree to prevent or delay product inhibition.
- the method of electrodialysis can be used to adjust the pH as needed to preferably 4 to 8.
- a better drug separation can be achieved by the technology.
- an implementation can take place directly in the seed growth reactors and / or separately from them.
- the condiments are produced by means of so-called high-gravity processes.
- the adjustment of the desired product composition is then carried out e.g. by dilutions with brewing water.
- the product is influenced to different degrees.
- mineralization is also given a special role because certain substances can lead to undesired reactions. For example, too high calcium content in the so-called Verschneidmedium lead to a later precipitation of calcium oxalates, which favor, for example, unwanted gushing. It is also important to exclude the entry of larger amounts of iron, since iron reduces especially the taste stability.
- the composition of the minerals and the pH values in the fractions are influenced by the ionization, a targeted blending medium treatment can be used for quality optimization.
- the medium should ideally be treated by electrodialysis prior to addition and brought to a pH preferably from 4 to 6.
- the fermentation organisms in beer production: the yeast significantly influence the characteristics of the products. Obtaining a physiologically vital, contamination-free culture is therefore indispensable. To ensure this, the populations are partially targeted, for example, treated with acid.
- a classical, adequate acidification of the microorganisms is relatively complex and partly declaratory.
- certain substances, such as hops resins are not sufficiently removed from the membrane surfaces, which, for example, reduces the reusability, or the effectiveness of the cells.
- ionized medium preferably with a pH of 2 to 4
- the fermentation and potential contaminating organisms can be specifically treated and their vitality / viability can be influenced.
- the product may also change in an undesirable manner (eg increase in color, Maillard products).
- the required system technology is relatively expensive and also means a high energy input.
- the debris can be treated and e.g. Nachisomermaschine and / or recovery of minerals are made.
- this process can be carried out in the container 7.
- This technology can be used to realize further raw material savings.
- the fluid used for the ionization, or at least a part thereof can be pretreated by means of material dispensing and / or substance removal.
- the undesired substances for example iron ions
- the undesired substances should be removed before the ionization.
- the electrodes 6a, 6b should ideally consist of, or at least be coated with, a metal which is as inert and therefore noble as possible (for example platinum, platinum-coated titanium), so as to dissolve out and undesirably enrich substances such as iron to avoid.
- a metal which is as inert and therefore noble as possible for example platinum, platinum-coated titanium
- the electrodes it is possible for the electrodes to consist wholly or partly of the metal or of an alloy of the metals which are desired in the process (for example magnesium).
- Such “sacrificial electrodes” may optionally be used exclusively, or in addition to the other electrodes.
- Positive for the hop isomerization for example, calcium, magnesium, titanium, nitrogen, ammonium and fluorine; negative iron and manganese.
- the process can be influenced by targeted fumigation of the liquids.
- aeration or introduction of ozone causes mineral complexes to precipitate and optionally be withdrawn from the process.
- the fumigation the homogeneity and thus the mass transfer efficiency can be increased.
- it can be used to control oxidation processes.
