Description

  The present invention removes or deactivates an undesired component in malt (hereinafter referred to as “malt remanufacturing” in the present specification), and a malt remanufacturing apparatus and method for improving the quality of beer. About. More specifically, the present invention relates to a factor (hereinafter referred to as “PYF factor”) that is considered to be an unfavorable component of malt because it induces an early aggregation and precipitation phenomenon (hereinafter referred to as “PYF”). ), And inactivate lipoxygenase (hereinafter referred to as “LOX”), which is an enzyme that produces an oxidant, and further, malt larvae that are said to contain a lot of LOX. The present invention relates to an apparatus and a method capable of removing malt and reprocessing malt.

  Examples of liquors produced by fermentation using malt as a raw material include yeast, beer, happoshu and whiskey. Lager type beers are brewed in Japan, Germany and other countries around the world. Recently, light type beer production has been increasing mainly in the United States, and in Japan, the production of Happoshu with a low malt blending ratio has increased. Yes. In brewing these beers or happoshu, bottom yeast, in which the yeast settles at the bottom of the fermentation tank after the completion of fermentation, is often used.

  Thus, when producing alcoholic beverages that use malt as a raw material, a phenomenon called “early coagulation sedimentation phenomenon of yeast” (PYF) may be observed during fermentation. This is a phenomenon in which the yeast agglomerates and settles, and as a result, the progress of the fermentation stops, even though the sugar that can be assimilated by the yeast still remains in the wort before the end of the fermentation. When this event occurs, sugar and amino nitrogen remain in the fermented liquid, and further, VDK (vicinal diketone) called so-called young odor and wort odor aldehyde called unsaturated fermentation remain, and beer, sparkling liquor, Alternatively, the quality of whiskey is significantly reduced. In producing high-quality beer and the like, it is desirable to reduce the PYF factor that attracts yeast PYF contained in the malt.

  In addition, when beer is stored for a certain period of time, there is a case where a deteriorated characteristic flavor is felt although there is a difference in level depending on the brand. One of the flavors of degraded beer is cardboard odor, and this degraded flavor is mainly composed of trans-2-nonenal (hereinafter referred to as “T2N”), and this T2N is mainly composed of malt lipid components. It is known to originate. In recent years, the influence of malt quality on beer flavor stability has attracted attention, and a malt nonenal potential (hereinafter referred to as “malt T2N-P”) analysis method has been developed as an index for evaluating this beer flavor stability. It became clear that beer with excellent flavor stability can be produced by using malt having a low analytical value (Patent Document 1). One factor affecting malt T2N-P is LOX, a lipid oxidase in malt, and it has been clarified that malt T2N-P is reduced by reducing this activity (Patent Document 2). This LOX is thought to be particularly localized in malt shoots. Therefore, in order to reduce the cardboard odor, it is desirable to reduce or deactivate the activity of malt T2N-P and / or LOX, or remove the young buds if possible.

  Furthermore, it is ideal that the process of regenerating malt as described above can be performed using existing equipment as much as possible without changing the flow of the conventional manufacturing process of beer and happoshu. Malt is always used after being pulverized by a pulverizer, and passes through the pulverizer during the manufacturing process. For example, it may be possible to remove the above components using an existing pulverizer.

  A wet pulverizer is known as a malt pulverizer. The structure of the wet pulverizer is described in Non-Patent Document 1, for example. As described in Non-Patent Document 1, the wet pulverizing apparatus for malt includes a malt hopper that accommodates dried malt, a condition cylinder that is provided below the malt hopper and that provides moisture to the malt, and a condition cylinder. And a pulverizer continuously provided below. The malt hopper and the condition cylinder, and the condition cylinder and the pulverizer are each partitioned by a gate valve, and these spaces are partitioned watertight while the gate valve is closed. Moreover, the malt hopper is provided with a malt inlet for supplying malt to the top wall. Moreover, the exit to the charging tank of the next process is provided in the grinder.

Therefore, a first object of the present invention is to provide an apparatus and method that can reduce the activity of LOX and T2N, which reduces the concentration of PYF factor in the malt, and causes a decrease in beer flavor stability. There is.
The second object of the present invention is to provide an apparatus and method for removing only malt seedlings while leaving the surface of the malt.
Furthermore, a third object of the present invention is to provide an apparatus that can perform the above object without changing the flow of conventional manufacturing processes such as beer and using existing facilities as much as possible.

  The object of the present invention is a malt wet pulverization apparatus comprising a malt hopper for accommodating malt, a conditioning room connected to the malt hopper, and a pulverizer connected to the conditioning room. In order to immerse the malt in the malt hopper, water supply means for supplying water at a predetermined temperature into the malt hopper, water temperature adjusting means for maintaining the water temperature in the malt hopper immersed in the malt at a predetermined temperature, It can be achieved by a wet pulverizing apparatus for malt having a malt remanufacturing function, characterized by having a waste water pipe for draining water in the malt hopper.

  In the wet pulverizing apparatus for malt according to the present invention, a predetermined amount of malt is supplied to the malt hopper, water is supplied into the malt hopper by a water supply means, and the malt is immersed in water in the malt hopper. At this time, the water in the malt hopper is maintained by the water temperature adjusting means. After the malt is immersed in water at a predetermined temperature for a predetermined time, the water in the malt hopper is drained through a waste water pipe. Thereby, the PYF factor contained in the malt dissolves in water, and the concentration of the PYF factor contained in the malt can be reduced.

  Further, if the water temperature is set to a relatively high temperature for immersing the malt, LOX and T2N-P can be deactivated or deactivated.

Furthermore, the outer side of the malt is covered with the husk, but the malt larvae have a higher rate of swelling with water than the endosperm portion, and the young buds have a higher rate of swelling than water. Therefore, by immersing the malt in water, the bud part expands larger than the endosperm part in the husk, the bud is easily released out of the husk, and only the bud is removed without removing the husk. Can be easily removed from the malt.
In addition, after the malt is immersed in water in the malt hopper, the water is once drained, and once again filled in the malt hopper with water or hot water (hot water) and immersed again, the PYF factor Removal and LOX and T2N-P deactivation can be performed satisfactorily.

  Moreover, in embodiment of this invention, in order to stir the water and malt in a malt hopper, it has a gas supply means for blowing in gas, such as nitrogen gas and a carbon dioxide gas, in a malt hopper. By blowing gas into the malt hopper by the gas supply means and stirring the water in the malt hopper, more PYF factor is dissolved in water, and a higher washing effect of the malt can be obtained. In addition, the malt immersed in water collides with the inner wall of the malt hopper by stirring, and the malts collide with each other to give a physical impact to the malt. Buds are released out of the husk. As a result, it is possible to eliminate from the malt the buds that are thought to contain a large amount of LOX.

  Furthermore, in the embodiment of the invention, the upper part of the malt hopper is further discharged so that water near the liquid level in the malt hopper is discharged while water is supplied from the water supply pipe into the malt hopper. With an overblow pipe connected to the While supplying water into the malt hopper from the water supply pipe, the water in the malt hopper is discharged through the overblow pipe to enhance the cleaning effect during the immersion of the malt, so that the PYF factor can be removed well. . In addition, the shoots released outside the husk have lower specific gravity than water and float near the surface of the water in the malt hopper, so that they float in the water by draining from the overblow pipe. Young shoots can be eliminated.

  Furthermore, in the embodiment of the present invention, there is further provided a circulation pipe connected to the malt hopper, and a pumping means for passing water and malt in the malt hopper through the circulation pipe and returning them to the malt hopper. While passing water and malt through the circulation pipe, the soaked malt collides with the inner wall of the circulation pipe, and while passing through the narrow passage, the malt collides with each other and the young buds are released out of the husk. It becomes easy to be done.

  Furthermore, in embodiment of this invention, it has a vapor | steam supply means for heating the malt containing water by immersion. In the state where the water in the malt hopper is drained through the waste water pipe, the activity of LOX contained in the malt is further reduced by heating the malt containing water by immersion with the steam released from the supply means. Or can be deactivated better. When the steam supply means is provided in the condition cylinder, the condition cylinder of the malt wet pulverization apparatus is generally narrower than the malt hopper, and the gap between the malt hopper and the pulverizer is sealed by a gate valve. Therefore, the whole malt accommodated by the steam can be heated. Further, by providing the steam supply means in the condition cylinder, it becomes possible to spray the steam within a short time during which the malt passes the condition cylinder.

  Furthermore, the above object of the present invention is a malt wet pulverization apparatus comprising a malt hopper for containing malt, a conditioning room connected to the malt hopper, and a pulverizer connected to the conditioning room. And it can also be achieved by a wet pulverizing apparatus for malt having a malt remanufacturing function, characterized in that the condition cylinder is provided with steam supply means for heating the malt. By treating malt at a high temperature in a condition cylinder, the activity of LOX contained in the malt can be lowered or deactivated, and the generation of T2N-P (T2N potential) can be suppressed. it can.

ADVANTAGE OF THE INVENTION According to this invention, the apparatus and method which can reduce the density | concentration of PYF factor in malt, and can reduce the activity of LOX and the density | concentration of T2N-P (T2N potential) which cause the fall of beer flavor stability. Can be provided.

Furthermore, according to the present invention, it is possible to provide an apparatus that can be performed using existing equipment as much as possible without changing the flow of conventional manufacturing processes such as beer.

The best mode for carrying out the present invention will be described below with reference to the drawings.
FIG. 1 shows the structure of a wet pulverization apparatus for malt provided with a malt remanufacturing function according to an embodiment of the present invention.

  As shown in FIG. 1, the malt wet pulverization apparatus 2 includes a malt hopper 4 that accommodates dried malt, a condition cylinder 6 that is provided below the malt hopper and that provides moisture to the malt, and further includes a condition cylinder 6. And a pulverizer 8 continuously provided below. The malt hopper 4 and the condition cylinder 6 and the condition cylinder 6 and the pulverizer 8 are respectively partitioned by a first gate valve 10 and a second gate valve 12 serving as a pulverizer supply sheet. . While these gate valves 10 and 12 are closed, these spaces are partitioned in a watertight manner.

  The malt hopper 4 has an upper surface part 14 of the malt hopper main body at the upper part, a malt inlet 16 for supplying malt to the lid part 14 is provided, and a malt supply pipe is provided between the malt supply device (not shown). 18 are connected. The crusher 8 is provided with an outlet 58 to a charging tank (not shown) for the next process. In addition, the condition cylinder 6 is provided with a water supply facility 20 for giving moisture to the malt before pulverizing the malt. Furthermore, a mill 22 for pulverizing the malt is provided in the pulverizer 8. The crusher 8 is connected to the charging tank of the next process by a pipe 24, and a first pump 26 is provided at the entrance of the pipe 24 on the side of the crusher 8 to pump malt to the charging tank. ing.

  The wet pulverizing apparatus 2 for malt according to the present embodiment immerses the malt in the malt hopper 4, so that the water supply means 28 for supplying water at a predetermined temperature into the malt hopper 4 and the malt hopper in which the malt is immersed It has a water temperature adjusting means 30 for maintaining the water temperature inside at a predetermined temperature, and a waste water pipe 32 connected to the bottom of the malt hopper 4 for draining the water in the malt hopper 4. The water supply means 28 includes a water supply pipe 34 connected to the malt hopper 4 and a boiler (not shown), and a valve 36 for adjusting a water supply amount provided in the water supply pipe 34. Water or hot water is supplied into the malt hopper through the water supply pipe 34. The temperature adjusting means 30 is provided with a thermometer (not shown) in the malt hopper. When the water temperature falls below a predetermined temperature, the valve 36 is opened and heated, and the malt is stirred by steam. The temperature of the water supplied into the malt hopper is adjusted to a predetermined temperature by adjusting the amount of water and hot water mixed by the valve 36. Further, the steam pipe 54 is partially branched, and the branched steam supply pipe 30 is connected to the malt hopper 4 so as to supply steam to the malt hopper 4. When the temperature in the malt hopper 4 is lowered, steam is supplied through the steam supply pipe 30 to raise the temperature to a predetermined temperature, and the malt is stirred by the steam.

  The wet pulverizing apparatus 2 for malt has a gas supply means 38 for blowing gas into the malt hopper in order to stir the water and malt in the malt hopper. The gas supply means 38 has a plurality of nozzles 40 directed into the malt hopper, and a gas pipe 42 connected to the nozzles 40 extends to a gas source (not shown). The nozzles 40 are arranged on the mutually opposing side walls of the malt hopper 4. Further, the nozzles 40 are arranged apart from each other in the height direction in the lower half in the height direction of the malt hopper 4.

  Further, the wet pulverizing apparatus 2 for malt has an overblow pipe 44 connected to the upper part of the side wall of the malt hopper 4. The overblow pipe 44 is for draining water in the vicinity of the liquid level in the malt hopper when water is continuously supplied to the malt hopper 4 by the water supply means during the immersion of the malt.

  Furthermore, the wet pulverizing apparatus 2 for malt has a water circulation means 46. The water circulation means 46 has a circulation pipe 48 whose both ends are connected to the malt hopper 4, and a second pump 50 as a pressure feeding means for circulating the water and malt in the malt hopper through the circulation pipe 48. . More specifically, the circulation pipe 48 has one end connected to the upper part of the malt hopper 4 and the other end connected to the lower part thereof. The second pump 50 is connected to the lower connection part of the circulation pipe 48. It is provided in the vicinity, and water and malt in the malt hopper can be circulated from the bottom to the top through the circulation pipe 48.

  On the other hand, the condition cylinder 6 is provided with steam supply means 52 for heating the malt containing water by immersion. The supply means has a steam pipe 54 having one end connected to a boiler (not shown) and the other end extending to the condition cylinder 6, and a steam jet 56 opening into the condition cylinder 6.

The malt wet pulverization apparatus 2 according to the present embodiment operates as follows.
1. Water immersion First, the first gate valve 10 between the condition cylinder 6 is closed. A predetermined amount of malt is supplied from the malt inlet 16 into the malt hopper through the malt supply pipe 18 of the malt supply device.
When a predetermined amount of malt is supplied to the malt hopper 4, the water supply valve 36 of the water supply means is opened, and water adjusted to a predetermined temperature by mixing hot water and water is supplied into the malt hopper. In this specification, “water” includes “warm water”. Water is supplied to the extent that the malt in the malt hopper is immersed. The water in the malt hopper is maintained at a predetermined temperature (a range of 0 to 100 degrees Celsius) by the water temperature adjusting means 30 during a predetermined immersion time (for example, 2 hours to 12 hours). By immersing the malt in water at a predetermined temperature for a predetermined time, the PYF factor contained in the malt is dissolved in water. Thereby, the content of the PYF factor contained in the malt can be reduced.

  In addition, if the temperature of water is set to a temperature that can reduce or deactivate LOX activity (relatively high temperature, for example, 60 to 90 degrees Celsius), malt contains T2N and LOX. Even if it is, they are deactivated by soaking, so that it is difficult to adversely affect the quality of beer and the like.

  Furthermore, the rate of swelling of the buds in the malt husks is higher than that of the endosperm, and the rate of sprouting is higher than that of the husks. It is easy to come off, and only young shoots go out of the husk. As a result, it is possible to extract only the young shoots from the malt without removing the husk. It is conceivable to remove the husk to remove the internal shoots, but the husk is necessary for wort filtration in Reuters in a later manufacturing process, so it is separated from the husk at this stage. It is not desirable to do so. According to the above method, it is possible to remove only the young shoots from the malt while leaving the husk intact.

  When the malt is immersed in water for a predetermined time, the water is drained through the waste water pipe 32. As a result, the water containing the PYF factor and detached buds is drained. Specifically, the water distribution pipe 32 is provided with a mesh 60 that is finer than the malt and larger than the young shoots, and can discharge only water and young shoots.

2. Water Stirring In the water immersion of 1 above, while the malt is immersed in water in the malt hopper, if necessary, gas is ejected from the nozzle 40 into the water by the gas supply means 38, so that the water in the malt hopper And the malt may be stirred. The gas is jetted from the nozzle 40 toward the center of the inner space of the malt hopper 4 from the mutually opposite side wall portions of the malt hopper 4 and flows in the water upward from below. Thereby, water and malt are uniformly stirred. As a result, more PYF factor contained in the malt is dissolved in water, and more malt shoots are released outside the skin.

3. Further, in the water immersion of 1 above, while the malt is immersed in water in the malt hopper, while the malt is immersed, water is continuously supplied to the malt hopper 4 by the water supply means 28, You may drain the water containing a PYF factor and a young bud from the overblow piping 44. FIG. Thereby, the concentration of the PYF factor dissolved in the water in the malt hopper 4 can always be kept low, and a higher washing effect of the malt can be obtained. Thereby, many PYF factors can be removed from the malt. In addition, since the specific gravity of the young bud is low, it tends to float on water when released from the husk. Therefore, young sprouts are easily discharged from the overblow pipe 44 near the liquid surface floating in the water.

4). Further, in the water immersion of 1 above, while the malt is immersed in water in the malt hopper, the second pump 50 is operated to circulate the water and malt in the malt hopper in the circulation pipe 48. You may let them. In the circulation, water and malt in the malt hopper are circulated from bottom to top through the circulation pipe 48. As a result, when the malt collides with the inner wall of the circulation pipe 48 and passes through the narrow pipe, the malts collide with each other, and the young buds swollen with water are easily released out of the husk.

5). Steam heating When the above-mentioned 1 immersion step is completed (optionally any of steps 2 to 4 above may be added), water is drained through a waste water pipe. Subsequently, the first gate valve 10 between the malt hopper 4 and the condition cylinder 6 is opened, and the malt is put into the condition cylinder 6. The second gate valve 12 between the condition cylinder 6 and the pulverizer 8 is closed. Since the second gate valve 12 between the condition cylinder 6 and the pulverizer 8 can be heated when the malt passes, it may be either closed or open.

  The first gate valve 10 is closed, the steam supply means 52 fills the condition cylinder 6 with steam, and the malt containing water by immersion is heated at a temperature higher than the immersion temperature in water (hot water) in the malt hopper. To do. Thereby, the activity of LOX can be further lowered or inactivated, and the production of T2N-P can be suppressed. This step can also be carried out in addition to the above step 1 and, if necessary, in addition to the above steps 2 to 4.

  Moreover, without performing any of the said processes 1-4, it is heated by the above after the process of moistening malt as usual before crushing malt with the condition cylinder 6, or it is heated simultaneously with moistening the malt with steam. It may be. As a result, T2N-P and LOX contained in the malt can be lowered and T2N-P can be suppressed. In this case, even if the malt contains young shoots, high-quality beer and the like can be produced by lowering LOX, which is said to be contained in large amounts in the young shoots.

  The present invention is not limited to the above embodiments, and various modifications are possible within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.

  For example, in the above embodiment, various means for performing the steps 1 to 5 are provided in the malt wet pulverizer 2, but it is not necessary to include all of these means, and the malt wet pulverizer. It goes without saying that these means may be provided in 2 as required.

  Further, in the above embodiment, the various means are provided in the malt wet pulverizing apparatus 2 to perform the malt remanufacturing process. However, a dedicated machine having a malt remanufacturing function separate from the malt pulverizing apparatus. It is good.

A water supply means 28 for supplying the water, a water temperature adjusting means 30 for maintaining the water temperature in the tank in which the malt is immersed at a predetermined temperature, and a waste water pipe 32 for draining the water in the tank are provided. Moreover, as shown in FIG. 2, you may provide the same means so that this apparatus may have the function of said 2-5.

  Furthermore, in the said embodiment, although the steam supply means 52 was provided in the condition cylinder 6, you may provide the steam supply means 52 in the malt hopper 4. FIG. By providing the malt hopper 4 with a steam supply means, the malt hopper 4 can be used for maintaining the temperature.

Furthermore, in the said apparatus, since the nozzle 40 of the gas piping 42 is provided in the side wall part which the malt hopper 40 opposes, and the lower part, the malt and water can be stirred favorably, It may be arranged at a position.
In the above apparatus, the upper end of the circulation pipe 48 is connected to the upper part of the malt hopper 4 and the lower end is connected to the lower part thereof, which is preferable in that the malt that has settled in the malt hopper 4 can be mixed up and down.
