Description

[Detailed description of the invention] This invention relates to a miso brewing container.

Miso brewing is made by adding koji and salt to steamed soybeans as raw materials for miso, and storing the mixture in a hot or cold brewing room for a certain period of time to ferment and mature. In connection with
Generally, cylindrical or rectangular cylindrical containers with a height and outer diameter of about 2 meters and an open top are used, and it takes a considerable amount of time for the temperature of the miso ingredients inside to approach room temperature depending on the part, ensuring even fermentation. There is a disadvantage that this is hindered. For this reason, conventional methods have been to embed a bottomed inner container in the miso of the brewing container and allow the inner surface of this inner container to communicate with the outside air to age the miso (Patent No. 29735), or to insert the top end into the brewing tank. A hollow cylinder with only one opening is supported, and only the inside is heated and cooled through heating and cooling pipes installed on the inner surface of this hollow cylinder and on the outer surface of the brewing tank.
No. 10238), but these internal containers and hollow cylinders are both separate from the brewing container, and only heat or cool a portion of the entire raw material.

On the other hand, the miso brewing container of this invention has a cylinder that protrudes inside the cylindrical container, the lower end of which opens on the bottom surface of the bottom plate, so that the outside temperature is transmitted to the center of the miso ingredients through the cylindrical wall surface. As shown in the drawings, the overall structure consists of a cylindrical container 1 made of metal such as stainless steel, with an inner cylinder 4 protruding from the center of the bottom plate 2, which is approximately at the same height as the peripheral wall 3 and whose lower end opens on the bottom surface of the bottom plate 2. It is formed by The closer the size of the inner cylinder 4 is to the diameter of the container, the better the heat conductivity will be, but in consideration of the reduction in the internal volume of the container, good results were obtained by setting the size of the inner cylinder 4 to approximately 1/4 of the diameter of the bottom plate. In the illustrated embodiment, the height of the peripheral wall and the diameter of the bottom plate are each 2 meters, and the diameter of the inner cylinder 4 is 0.5 meters.

This idea has the above-mentioned structure, and originally each brewing container was placed with a pillow material in between in the brewing room, so
Room temperature is transmitted to the miso ingredients inside through the outer surfaces of the peripheral wall 3 and the bottom plate 2 and the inner surface of the inner cylinder 4, and since the peripheral wall 3 and the inner cylinder 4 are concentric cylinders, the temperature distribution over the miso ingredients is even. . That is, when the temperature of the miso raw material is higher than room temperature, the air in the inner cylinder 4 rises due to convection, and when the temperature is lower than room temperature, it falls. In this way, the indoor air is circulated. As a result, when miso ingredients are placed in a brewing container with the above dimensions at 41°C and brewed cold (brewed at room temperature), the time required for the temperature to drop is longer than in a conventional 2m x 2m cylindrical container. It turned out to be less than half.

Furthermore, this invention has many advantages, such as being able to continuously determine the fermentation temperature of the miso raw material by attaching a detection device to the inner surface of the central inner cylinder 4.

[Brief explanation of the drawing]

The drawings show an embodiment of this invention, with FIG. 1 being a plan view and FIG. 2 being a longitudinal sectional view. In the figure, 1 indicates a cylindrical container, 2 indicates a bottom plate, 3 indicates a peripheral wall, and 4 indicates an inner cylinder.

Claims (1)

[Scope of utility model registration request] In the miso brewing container placed on the pillow material, a circular hole with an inner diameter of approximately 1/4 of the bottom plate diameter is opened in the center of the bottom of the metal right cylindrical container 1 with an open top, and the lower edge is connected to this circular hole. This miso brewing container is made up of a right cylindrical inner cylinder 4 that is connected to the mouth rim and opened at the upper and lower ends and whose height is approximately equal to the peripheral wall 3 of the metal right cylindrical container 1.
