DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for producing low-malt beer produced by using more raw materials (auxiliary raw materials) than malt in alcoholic beverages using malt. The present invention relates to a charging method for avoiding filtration congestion in a process.

[0002]

2. Description of the Related Art Alcohols such as beer and low-malt beer manufactured using starch materials such as malt and rice, corn and starch are first prepared in a charging process by using malt and auxiliary materials such as rice, wheat, and so on.
Corn, starch and other starch raw materials are mixed together and kept at an appropriate temperature in warm water for an appropriate time to make a mash, the mash is saccharified by the action of malt enzymes, and then filtered to remove the filtered wort. It is done by obtaining.

[0003] In the filtration step, a filtration net at the bottom of the filtration tank and a husk layer formed of hulls of malt deposited on the upper surface of the filtration net function as a filter. Juice can be obtained.

[0004]

However, in malting liquor produced using malt as a raw material, malt is used in an amount less than that of an auxiliary material (rice, corn, starch, etc.) because the amount of malt is small. The aforementioned hull layer becomes thinner,
Filtration congestion occurs at an early stage of filtration, resulting in a significant increase in filtration time. In extreme cases, there is a risk that filtration becomes impossible during filtration.

[0005] The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a method for avoiding filtration congestion in the preparation process in the production of happoshu using more auxiliary materials than malt. It is intended for.

[0006]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, in the process of preparing low-malt beer, using a brewing tank and a brewing kettle, the malt is heated in the brewing tub. To form a malt meshy, and in the brewing kettle, mix the auxiliary raw materials with warm water to form an auxiliary raw material mash, precede the filtration of the malt maiche in the brewing tank, and subsequently follow the auxiliary raw material mesh in the brewing kettle. After that, it was found out that the filtration congestion in the filtration tank could be avoided by mixing and boiling the two filtrates, thereby completing the present invention.

According to the present invention, there is provided a step of using malt and an auxiliary material in an amount larger than the malt, boiling the auxiliary material in a charging pot to form an auxiliary raw material mash, and mixing malt and hot water in a charging tank. Decomposing the protein by elapse of a predetermined time at a predetermined temperature to form a malt meshy; and elapse of a predetermined time at a predetermined temperature at the auxiliary material meshe formed by the charging tank and the malt meshy formed by the charging tank. A saccharification step of saccharification, a filtration step of filtering the saccharified mash and obtaining a clear filtered wort, a boiling step of boiling the filtered wort to obtain hot wort, and cooling the hot wort. A fermentation step of refining and fermenting, and a method of producing malting liquor comprising the steps of: saccharifying a malt meshy formed in the mashing tank; It is characterized in that performed separately and filtration process. This separation in the filtration step can be achieved by using a common filtration tank for the malt mesh and the auxiliary raw material mesh at different times, or by installing a dedicated filtration tank for each.

Further, according to the present invention, when a common filtration tank is used, the step of filtering malt meshes formed in the charging tank is performed prior to the step of filtering auxiliary raw material meshes formed in the charging tank. This makes it possible to avoid filtration congestion. In addition, one feature of the present invention is that the saccharification step of the auxiliary raw material meshes formed in the charging tank is performed in the charging tank. In this case, the auxiliary raw material meshes that have undergone the saccharification step are filtered from the charging tank. Transport means for directly transporting to the tank is provided.

In the present invention, the auxiliary raw material meshes in the charging pot are heated and then boiled as usual. Prior to this, an exogenous enzyme (for example, α-amylase, β-amylase, protease, β-glucanase, pullulanase, etc.) is added to the auxiliary raw material mesche in order to deal with starch degradation in the auxiliary raw material. In some cases, a small amount of malt fines can be added in addition to the foreign enzyme.

On the other hand, the above-mentioned foreign enzyme can be added to malt mash. The present invention also provides a charging tank for forming malt meshes, a charging pot for forming auxiliary material meshes, and a filtration tank for filtering meshes.
Boiler for boiling the saccharified liquid, and a fermenter for fermenting the saccharified liquid, malt including the malt and an apparatus for producing low-malt beer using auxiliary materials in a larger amount than the malt,
It is characterized by comprising a conveying means for directly conveying the auxiliary raw material meshes from the charging tank to the filtration tank, and / or a malt meshy exclusive filtration tank and an auxiliary raw material meshy exclusive filtration tank.

The provision of these devices makes it possible to avoid or eliminate congestion in filtration in the production of low-malt beer that uses more auxiliary materials than malt. In the present invention, the malt meshy in the charging tank is subjected to a saccharification step after a protein rest period as usual. Conventionally, this saccharification step has been performed after being mixed with the auxiliary raw material meshes in the boiler after boiling, but in the present invention for avoiding filtration congestion, mixing with the auxiliary raw material meshes in the saccharification step is not performed. . After the malt mash is saccharified, it is transferred from the charging tank to the filtration tank, and the filtration step is started.

Examples of the auxiliary raw materials in the present invention include sugar substances such as rice, barley, wheat, corn, starch, kuryang, potatoes, various starches, liquid sugar, and sugar. The amount of the auxiliary material used is more than half of the total amount of the material except water. After the boiling treatment, the auxiliary raw material mash is added without being mixed with the malt mash from the preparation tank, the temperature is adjusted to a temperature suitable for saccharification, and the mash is transferred to the saccharification process. At this time, it is preferable to add an exogenous enzyme such as β-amylase to the auxiliary raw material meshet. This saccharification step can be performed in either the charging pot or the charging tank. When saccharification is performed in the charging tank, the auxiliary raw material mash is not directly transferred to the filtration tank by the transfer means of the present invention without passing through the charging tank after the saccharification is completed. When saccharification is performed in the charging tank, the auxiliary raw material meshes are transferred to the charging tank when the malt meshes in the charging tank are conveyed to the filtration tank and the charging tank is empty or there is a small amount of residual meshies. Will be After completion of the saccharification step, the auxiliary raw material mash is also subjected to the filtration step.

[0013] In the present invention, when a common filtration tank is used for the malt mesh and the auxiliary material mesh, the filtration of the malt mesh is performed prior to the filtration of the auxiliary material mesh. As an actual procedure, first, the malt mash that has passed through the saccharification step is transported to a filtration tank, and the filtration step is started. At this time, the malt meshes are not mixed with the auxiliary material meshes containing the fine residue, so that the filtration step can proceed smoothly as compared with the case where the malt meshes are mixed. Before or immediately after the filtration step of the malt meshes is completed, the auxiliary material meshes are conveyed to the filtration tank and filtration of the auxiliary material meshes is started. Regardless of the amount of auxiliary raw material meshes, the filtration time is reduced by up to about one third compared with the conventional case. In the present invention, it is preferable to perform time adjustment of all steps prior to the filtration step in consideration of the time difference between the filtration of the malt mesh and the filtration of the auxiliary material mesh.

In the present invention, as shown in FIG. 1, the auxiliary raw material meshes are transferred from the charging tank (2) to the filtration tank (2) by a conveying means provided between the charging tank (2) and the filtration tank (3). 3) provided directly. Further, as shown in FIG. 2, a filtration tank (4) dedicated to malt mash and a filtration tank (5) dedicated to auxiliary raw material mash may be provided to perform the filtration step separately.

Next, the filtered wort from both the malt mash and the auxiliary mash obtained through the filtration step according to the present invention is mixed, and after adding hops and the like, it is boiled in a boiling pot (6). An example of a process of performing the filtration process of the malt mesh and the auxiliary material mesh at a time interval,
FIG. 3 shows changes in the charging pot meshes and the charging tank meshes over time as compared with the conventional example.

Hereinafter, the present invention will be specifically described with reference to examples. However, they illustrate the invention and do not limit it in any way.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Example 1 (1) Preparation of sample The amount of malt used was 24% of the total raw materials (excluding water), and the other raw materials were auxiliary raw materials (rice, wheat, corn, starch, etc.). ) Was used. (2) Production process First, malt mashes after saccharification are filtered in a charging tank. Here, in the wort filtration, as in the case of beer, the first wort filtration is performed for both the malt mesh and the auxiliary raw material mesh, and then the second wort filtration is performed in which hot water is added to the residue to extract and filter the wort extract in the residue. Next, the auxiliary raw material mash that has been saccharified in the brewing pot,
Filtration is performed using the filtration tank previously used for filtering malt maiche. In this case, as shown in the processing procedure of FIG. 3, the auxiliary raw material meshes in the charging kettle are transferred to the filtration tank during the filtration of the malt meshes, and the filtration is continued. It is convenient to transfer the auxiliary raw material mesh to the filtration tank after the wheat tank is formed in the filtration tank by the filtration of the malt mesh. Of course, the filtration of the auxiliary raw material meshes may be continued after the filtration of the malt meshes is completed, but the former is more effective in view of shortening the working time. In addition, in the preparation step for obtaining wort in order to decompose starch as an auxiliary material, a foreign enzyme (α-
Amylase, β-amylase, protease, β-glucanase, pullulanase, etc.). Regarding the addition time of this enzyme, in the preparation step, an enzyme that is adapted to each of the liquefaction of the auxiliary raw material meshet and the saccharification step of the auxiliary raw material meshet is required.
Amylase) is charged at the same time as the addition of the auxiliary raw material to the charging tank or until the temperature reaches the optimum temperature of the enzyme to be used in the step of forming a mash. In addition, it is preferable to add the enzymes necessary for saccharification at the start of the saccharification step (β-amylase, which is a saccharification enzyme, is weak at high temperatures (about 70 ° C.) and immediately deactivated. Since the temperature is raised to about 100 ° C. in the raw material meshy forming step, it is not possible to put in the step before the saccharification step). The obtained filtered wort as an auxiliary material is mixed with the filtered wort of the aforementioned malt mash and transferred to the boiling step.

As a control, a conventional example was manufactured through the steps shown in the schematic steps of FIG. That is, malt is put into a charging pot and a charging tank at a ratio of 1: 2, respectively, to form malt + auxiliary material mash and malt mash, and then malt + auxiliary material mash in the charging pot is charged in the charging tank. The mash was mixed with malt mash (in the brewing tank) and filtered through a saccharification step. (3) Results The filtration times according to the present invention and the conventional example are shown in FIG. Separate the mash and mashing tank separately
Moreover, even if the filtration is performed continuously in one filtration tank, the filtration time according to the present invention is reduced by 50 to 60%. The other steps in the charging process are the same as the conventional example, and the operation time is almost the same. Therefore, the shortening of the required time of the filtering process directly leads to the shortening of the entire charging process (from malt mesh filter to auxiliary material mesh filter). Although some time is required at the time of switching, it is about +10 minutes even when the filtration is performed after the malt meshe filtration is completed and then the auxiliary raw material meshes are all transferred to the filtration tank.) Even in comparison with the required time of the charging step including the filtration step, in the case of the present invention, the auxiliary raw material meshes are transferred to the charging tank to perform saccharification, and a series of operation times to obtain a saccharified solution is substantially equal to the filtration time of malt meshes. Therefore, the shortening of the filtration time substantially reduces the total time of the entire process.

In the case of performing filtration in a dedicated filtration tank, the filtration can be completed in the filtration time of the auxiliary raw material meshes, and can be further reduced (100 to 120 minutes, compared with the conventional example). 1/2 to 1/3).

[0020]

As described above, according to the method for producing a low-malt beer according to the present invention, it is possible to produce a low-malt beer without causing filtration congestion in a filtration step. Also,
The time required for the manufacturing process can also be reduced.
