Abstract

PURPOSE:In production of refined SAKE using ground rice obtained by grinding polished rice as a raw material, to produce high-quality refined SAKE, by grinding the polished rice in an oxidation preventing atmosphere in which a carbonic acid gas, etc., is sealed. CONSTITUTION:In production of refined SAKE using ground rice obtained by grinding polished rice as a raw material, the polished rice is ground in an oxidation preventing atmosphere in which a carbonic acid gas or another inert gas is sealed. Consequently, the grinding process can be carried out without bringing the polished rice into contact with atmosphere, so that oxidation during the grinding process can be completely prevented. Since the raw material of the high-quality ground rice can be successively treated in the following processes, high-quality SAKE can be manufactured.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing sake using pulverized rice, in which sake is produced using pulverized rice obtained by pulverizing white rice as a raw material.

Recently, a method for producing sake using pulverized rice as a raw material has been developed in order to improve raw material utilization, but pulverized rice that has been pulverized into fine particles has a significantly increased surface area, making it highly susceptible to oxidation. Especially during the grinding process, the contact time with the atmosphere is long, so the oxidation of the ground rice used as a raw material progresses, which has a negative impact on the production of high-quality sake.

In view of these drawbacks, the present invention provides a method for producing sake using pulverized rice obtained by pulverizing white rice as a raw material, in which the pulverization of white rice is carried out in an oxidation-preventing atmosphere filled with carbon dioxide gas or its underground active gas. An embodiment of the present invention will be described below with reference to the drawings. 1 is an automated sake production line. A packet conveyor 3 is disposed at the starting point to continuously transport the highly refined white rice raw material 2 upward, and the packet conveyor 3
A white rice hopper 5 capable of accommodating one day's worth of processing is continuously placed in the dropping chute 4 of the white rice hopper 5, and one end of a white rice screw feeder 6 is placed at the lower outlet of the white rice hopper 5, and one end of the transfer P is placed at a lower position. A pulverizer 7 such as a roll crusher for pulverizing the polished rice raw material 2 is arranged at the lower outlet of the pulverizer 7, and one end of a screw feeder 8 for taking out the pulverized rice for forcibly transporting the pulverized rice in the horizontal direction is installed at the lower outlet of the pulverizer 7! ! At the same time, a screw conveyor 9 for transferring the crushed rice upward is continuously arranged at the transfer end, and a vibrating sieve 11 and a crushed rice dumper 12 are placed below the dropping chute 10 connected to the upper transfer end. They are installed consecutively.

The vibrating sieve 11 has two sieves 13.13a arranged in series, and particles with a particle diameter of approximately 1.5 m/s or more are sieved at the upper @ 13 and are then re-injected into the crusher 7 by the return vibrator 14. On the other hand, the crushed rice that has passed through the upper sieve 13 is passed through the lower sieve 13a, with fine grain rice having an average grain size of approximately 0.6 m/w to 1.5 m/w on the sieve and average grain size approximately 0.6 o+ under the sieve. The sieve is made to pass through the sieve to rice flour with a particle size of less than /m.

The transportation path for the crushed rice from the crusher 7 to the crushed rice dumper 12 is sealed to be isolated from the atmosphere, and the transportation path is filled with carbon dioxide or other inert gas to create an oxidation-preventing atmosphere. The milled rice raw material 2 is pulverized and sieved in the atmosphere.

Also, below the crushed rice dumper 12 is an automatic crushed rice dispensing valve 1.
5, a fully automatic pressure feeding tank 16 is arranged, and a compressed air supply pipe 17 is connected to the fully automatic pressure feeding tank 16, and one end of a pressure feeding vibrator 19 is connected to the outlet at the bottom via an automatic crushed rice discharging valve 18. is connected, and the pulverized rice flour is liquefied by the air pressure of the compressed air supply pipe 17. ! 2
0. Sake mother! ! ! 21 and the fine grain rice to the fine grain rice processing device 22 for koji making in the koji making process, the pulverized rice is forced to be fed in a short time using compressed air. For this reason, the oxidation of the ground rice during such a transfer process is negligible.

In the figure, 23 is a koji making device, and 24.24a is a fermentation tank.

Next, to explain the raw material processing process, the highly refined white rice raw material 2 is continuously transferred upward by the packet conveyor 3, is thrown into the white rice hopper 5 from the drop chute 4, and is kept in the white rice hollover 5 for one day. The used amount is stored and sequentially fed from the lower part by a white rice screw feeder 6 and transferred to a crusher 7.

In the pulverizer 7, the polished rice raw material 2 is finely pulverized as it passes between rolls in an oxidation-preventing atmosphere filled with carbon dioxide gas, etc., and the processed pulverized rice is sequentially pulverized laterally by a screw feeder 8 for taking out the pulverized rice. Along with being transferred,
At the end of the transfer, the particles are transferred upward by the screw conveyor 9 and thrown into the vibrating sieve 11 through the falling shoe 10, where they are first passed through the upper sieve 13 to remove particles with a diameter of about 1.5 mats.
The insufficiently crushed rice is sieved and re-injected into the crusher 7 through the return vibrator 14, and the crushed rice that has passed through the force cylinder 13 is further passed through the lower sieve 13a with an average grain size of approximately 0.6~ It is sieved into fine grain rice of 1.5 m/s and rice flour with an average grain size under the sieve of about 0.6 m+/m or less.

The process of sieving crushed rice into fine grain rice on the sieve and rice flour on the bottom of the sieve is as follows:
Rice flour, which has a large surface area, is suitable for increasing the efficiency of liquefaction or sake mash production.On the other hand, compared to rice flour, coarse-grained, fine-grained rice has a large porosity, so it has good steam permeability and is a raw material for making koji. This is because it passes through.

Then, the sieved rice flour passes through the automatic crushed rice discharging valve 15 and reaches the fully automatic pressure feeding tank 16 below, where it passes through the pressure feeding vibrator 19 by air pressure from the compressed air supply pipe 17 and is sequentially forced to the subsequent process. It is.

In short, the present invention is a method for producing sake using pulverized rice obtained by pulverizing white rice as a raw material, in which the pulverization of white rice is carried out in an oxidation-preventing atmosphere filled with carbon dioxide gas or other inert gas. Since the pulverization process can be carried out without contacting the atmosphere, oxidation of the pulverized rice during the processing stage can be completely prevented, and the pulverized rice can then be processed as a raw material in subsequent processes.
Its practical effects, such as the ability to produce high-quality sake, are tremendous.
