Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a miso manufacturing method and a manufacturing device, in particular, automatically performing a koji making process using a rotary tank,
The present invention relates to a miso production method and production device that can produce homogeneous miso.

In the conventional miso production method, the growth state of Aspergillus oryzae during the koji making process is determined based on the subjective opinion of an expert based on visual observation and measured values of temperature changes by an expert. In addition, in conventional methods, as manufacturing equipment becomes larger, the temperature of the contents of the manufacturing tank tends to vary locally and become uneven, so the temperature at multiple locations within the tank is measured and the temperature is adjusted accordingly. The state of koji production was subjectively judged by an expert based on the average value of , but it was difficult to know these temperatures accurately and quickly. In particular, since there are individual differences in determining the growth status of Aspergillus oryzae by observation, there are disadvantages in that the quality of the finished koji becomes uneven and the yield expressed in terms of product weight decreases. Furthermore, in the conventional method, the raw materials before koji making and the finished koji after making koji were taken out from the tank and their weights were measured. This method requires a long time for measurement, and it is impossible to measure weight changes during the koji making process, so it is not possible to automatically produce high quality and homogeneous miso.

SUMMARY OF THE INVENTION An object of the present invention is to provide a miso production method and production apparatus that can eliminate the above-mentioned drawbacks and automatically produce high-quality and homogeneous miso.

The miso manufacturing method of the present invention includes a measuring step of measuring the weight of a rotary tank for making koji for miso, supplying miso manufacturing raw materials such as koji raw materials, water, and additive components into the rotary tank, and A miso material supply step in which the supply of the miso manufacturing raw material is stopped when the weight of the tank reaches a predetermined value, and the air in the rotary tank is adjusted in response to changes in the weight of the rotary tank; It consists of an automatic koji making process that rotates a tank. In this way, since the koji making process is performed in response to changes in the weight of the tank, the present invention can automatically produce high quality and homogeneous miso. In the miso material supply step, steam is supplied into the rotary tank. Air conditioning also controls the temperature and humidity inside the rotary tank.

Furthermore, the miso manufacturing apparatus of the present invention is used directly to carry out the above-mentioned miso manufacturing method, and is placed under a pedestal that supports a rotary tank for making miso koji, and is arranged under a pedestal that supports a rotary tank for making miso malt, so as to prevent changes in the weight of the rotary tank.

It consists of an air conditioner that is driven by control output and adjusts the temperature and humidity inside the rotary tank. Furthermore, this device has a temperature sensor that detects the temperature inside the rotary tank as an electrical signal.The electrical signal of this temperature sensor is input to the microcomputer, and the output of this microcomputer controls the motor and air conditioner. Driven.

During the koji process for making miso, carbohydrates are decomposed as metabolic energy by the growth of koji mold, carbon dioxide gas and water are released, and water evaporates due to heat generation, so the weight of the content decreases. Miso is manufactured by understanding this as an accurate physical quantity. In addition, the miso production method of the present invention completely eliminates the subjective comprehensive judgment based on observation of the state of koji mold and temperature measurement in the conventional method, and detects changes in the weight and temperature of the contents in the rotary tank as accurate physical quantities. This includes an automatic koji production process in which the state of growth of koji mold is constantly monitored, and temperature control and koji stirring can be carried out at accurate times and for the appropriate amount of time according to a predetermined program.

In the above configuration, to explain the miso manufacturing method of the present invention, first, the control valve 12 and the air intake valve 14 connected to the air conditioner 6 are closed, and the moisture content is 13%.
1000 kg of raw wheat is supplied to a rotary tank 10 by a screw conveyor 1. After that, water supply valve 2
is opened to supply water into the tank 10, and the motor 3 is activated to rotate the tank 10 and start washing grain. After about 5 minutes, the water supply valve 2 is closed, and after 10 minutes, the rotation of the rotary tank 10 is stopped and at the same time, the drain valve 4 is opened to drain the water in the tank 10. Furthermore, after 5 minutes, the drain valve 4 is closed, and the above operations from opening the water supply valve 2 to closing the drain valve 4 are repeated one more time to complete the grain washing process.
