CONSTITUTION:This beer brewing apparatus is composed of a heat-insulation vessel 1 closable with a lid 7 and furnished with a heating and cooling means 2 having an automatic temperature controlling device, a discharging cock 4 and a degassing cock 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beer brewing device suitable for small-scale brewing such as brewing at home.

[0002]

2. Description of the Related Art In order to brew a small amount of beer at home or the like, first, a commercially available malt extract is dissolved in water and placed in a suitable container and boiled. Next, water is added to this to increase the amount, and the mixture is transferred to a brewing container, the liquid temperature is maintained at an appropriate fermentation temperature, yeast for beer brewing is added, and primary fermentation is performed for about 1 week. After the primary fermentation, bottling is carried out, and the liquid temperature is kept at the optimum temperature for fermentation to about 1-2.
Aged for a month. Then, after the aging, it is cooled in a refrigerator or the like.

[0003]

However, in the conventional brewing of beer described above, in the step of bottling after the primary fermentation, various bacteria in the air are mixed by opening and closing the lid, etc., especially in the summer. ~ 26 ° C fermentation,
Since it could not be maintained at the aging temperature, the aging was not successful and the brewing of beer sometimes failed.

Therefore, the present invention, in the conventional brewing of beer described above, prevents miscellaneous bacteria in the air from being mixed, and can maintain the fermentation and aging temperature at about 18 to 26 ° C. It was made for the purpose of providing a beer brewer that eliminates the mistakes made in.

[0005]

Therefore, in the beer brewer of the present invention, the heat insulating container 1 can be sealed with the lid 7, and the heating and cooling means 2 with the automatic temperature control device 8 and the pouring plug 4, And a gas vent 6 are provided.

In the beer brewer of the present invention, the heating / cooling means 2 is a thermoelectric power generation / thermoelectric cooling device using a thermoelectric element, or the pouring plug 4 is provided with a filter 3 attached thereto. preferable.

[0007]

Since the beer brewing machine of the present invention is provided with the above means, it is possible to enter the aging step in the primary fermentation environment without opening and closing the lid or transferring the lid during the brewing step. The various bacteria do not mix.

Further, in the beer brewer of the present invention, the temperature is controlled by the automatic temperature control device 8 to a fermentation and aging temperature of about 18 to 26 ° C.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a beer brewing machine of the present invention will be described in detail below with reference to the drawings shown as embodiments.

As shown in FIG. 1, the beer brewing machine of the present invention is provided with a heating / cooling means 2 equipped with an automatic temperature control device (not shown) at the bottom of the heat insulating container 1, and the heat insulating container 1 side. The part is equipped with a pouring plug 4 with a filter 3 and a thermometer 5. Then, the heat insulating container 1 is sealed with a lid 7 having a gas vent 6.

The beer brewer of the present invention, as shown in FIG. 2, is provided with a heating / cooling means 2 provided with an automatic temperature control device 8 inside a lid 7 for sealing the heat insulating container 1. It is assumed that the side wall of the heat insulating container 1 is provided with a pouring plug 4. In the heat insulating container 1, a substantially U-shaped heat transfer rod 9 made of an aluminum rod or the like is hung from the heating / cooling means 2, and a thermometer 5 is hung from the automatic temperature control device 8. There is. Although not shown, a gas vent 6 is provided at an appropriate position on the heat insulating container 1 or the lid 7.

The heat insulating container 1 has a heat insulating material 12 such as styrofoam or glass wool inserted between an inner cylinder 10 and an outer cylinder 11. The capacity shown in this embodiment is about 10 liters.

As the heating / cooling means 2, a resistance heating device, an induction heating device, a compression cooling device or an absorption cooling device may be used, but a thermoelectric generator using a thermoelectric element and a thermoelectric cooling device are used. This is preferable for downsizing the beer brewing machine.

For example, the heating / cooling means 2 shown in FIG.
Is a Peltier element used as a thermoelectric element,
A direct current is caused to flow through two types of semiconductors (not shown) interposed between the metal plate electrodes a and b to cause heat absorption or heat generation at each junction.
A radiating fin 13 is connected to the metal plate electrode a, a heat transfer rod 9 is connected to the metal plate electrode b, and a paper or wood chip is placed between the metal plate electrodes a and b. Are connected by a honeycomb structure 14 made of a material having a low thermal conductivity such as. Further, a fan 15 attached to the upper portion of the lid 7 is arranged above the heat radiation fin 13.

The heating / cooling means 2 is about 18 to
The fermentation and aging temperature of about 26 ° C can be heated and cooled, and the brewed beer can be cooled to about 0 to 5 ° C.

In the lid 7 shown in FIG. 1, the heat insulating container 1 can be sealed by using a clamp 16 and can be provided with a peep window (not shown) if necessary.

Brewing beer using the beer brewing apparatus of the present invention having the above-described structure is performed as follows.

First, a commercially available malt extract is dissolved in 2 liters of water, placed in an appropriate container and boiled. To this, add 8 liters of water to make the total volume 10 liters.
Put in.

Next, the liquid temperature is set to 1 by the heating / cooling means 2.
Fermentation at about 8 to 26 ° C, heating or cooling to a aging temperature, adding yeast for beer brewing, sealing the heat insulating container 1 with a lid 7, and controlling the liquid temperature under the temperature control by an automatic temperature controller 8, Primary fermentation is carried out for about 1 week while maintaining the aging temperature. The state of fermentation can be directly confirmed by eye through the viewing window of the lid 7. Further, carbon dioxide gas generated during the fermentation process is appropriately released by the gas vent 6 of the lid 7.

After the primary fermentation, the liquid temperature is further aged for about 1 to 2 months while the liquid temperature is maintained at the fermentation and aging temperature under the temperature control by the automatic temperature control device 8.

After the aging, the brewed beer is cooled to about 0 to 5 ° C by the heating and cooling means 2 and stored.
