Description:
HOME BEER BREWING DEVICE

The object of the invention is a home brewing device provided with a closed container with malt raw material in it, which fits into the mashing and heating vessel, and is connected to an inlet tube of heating and sparging water. Furthermore, the closed container is provided with an aperture draining away sparging water from it after brewing.

Home brewing is increasingly spreading due to the demand for higher quality beer compared to industrial beers, the lower cost and also because of the adventure of making home-made beer.

There are three types of home-brewing: brewing from beer concentrate, from malt extract, and the all-grain process. The all-grain process is used at the professional breweries as well. The three main steps of the all-grain method are: mashing, sparging and heating, after which the wort is heated and cooled, and finally fermented. The all-grain method is highly flexible and allows for brewing many types of beers.

Our invention intends to develop a brewing device for the all-grain type home-brewing, specifically for the mashing and sparging phases of the method.

There are various devices for brewing beer at home, in which the processes of mashing and sparging are carried out in the same container. Such a device is presented in the US4754698 patent, for example. In the case of such solutions the mashing and sparging (i.e. rinsing the sugar left in the hulls) take place in the same container. The disadvantage of this procedure is that the containers need to be cleaned during the processes. Another drawback is the use of an extra stirring paddle which requires special attention when cleaning up and also at ensuring the necessary hygiene before the brewing.

There are other ways of mashing and sparging in which the malt is bought in pre-packaged containers made of a flexible material, for example in the case of the EP 0071365 European patent. In this brewing procedure, which uses malt extract, the substance to be fermented is sold in pre-packaged containers with the mixture of the right ingredients.

An obvious disadvantage of this in the all-grain method is that the container cannot be used during the whole procedure of brewing necessary for the mashing. Apart from this, stirring is also more difficult due to the flexible walls of the container. In this method exposing the raw material is done at room temperature for a longer period of time, which is also a drawback.

A similar method using flexible malt containers is widely known in the so called "brew in a bag" procedure.

The advantage of this is the easy handling after exposing the hulls: you simply take out the malt net from the brewing container after the mashing and sparging.

However, when using this method, you have to pay special attention to hygiene and the right amount of the ingredients, not to mention the possible clotting of the measured ingredients, and you have to pay attention to adequate stirring as well.

By developing the home-brewing device under the sample number U1400158, our aim was to create a mobile malt container and brewer for mashing and sparging which, compared to the methods described above, easily solves the problem of ensuring the adequate hygiene of the environment and proportioning the ingredients with the help of a sealed, firm-walled container already containing the different ingredients for brewing beer, ready to be distributed. Other advantages are that it can easily be attached to the existing brewing containers, and it uses a water spout system for stirring. After the mashing and sparging, the wort can be easily drained from the hulls through a layer of malt that works as a filter and through an aperture at the bottom of the malt container into the liquid collecting container.

Based on our experience gained during the technical development process we have improved the device further, and we discarded or transformed the faulty parts.

The technical solution proved to be disadvantageous since creating and fixing the inner separating lamina which controls the liquid flow was difficult. Besides, separating the brewing water from the sparging water with the help of an inner perforated lamina in the container for introducing liquid and the closed space containing the malt was not efficient enough from the point of view of stirring.

The invention, therefore, is a malt brewing and mashing device for home use, which comes with a capsule containing the malt for brewing beer, as well as a container for collecting the liquid below the sealed capsule and a pipe to ensure liquid flow between the two. The container which collects the liquid has an aperture for draining the malt wort after brewing. The capsule which contains the adequate quality and amount of malt necessary for brewing beer can be safely sealed to resist the stress it might be exposed to during trading processes. It comes with a removable filtering lid with an aperture on top which allows the flow of the brewing water or the sparging water. The closed space containing the malt within the sealed capsule is formed in a way that allows the liquid to flow back and forth between the container of the malt and the liquid-collecting container under the sealed capsule through a perforated filtering head formed at the top end of the feeding tube and through the filtering layer at the bottom of the malt container between the heating and stirring periods of the heating and sparging phases. There is a fixed support unit for the sealed capsule on the inner cover surface of the malt container/brewer device; and there is an outlet aperture for draining the malt wort on the outside of the bottom of the lower collecting container for easy draining.

Another strength of the design is that it is formed in such a way that on the inner surface of the malt container/brewer the parts of the support unit are situated opposing each other, thus, inserting, securing, and removing the sealed capsule can be carried out by turning the support unit by 90 degrees on the vertical axis.

Other advantages of the design are the following:

• The perforated filter head is made of aluminum foil, a material different from that of the malt container, and it is accepted in the food industry.

• The portable malt container/brewer device has an external casing common in kitchen appliances, and it has a removable lid and the panel of an automatic system controlling the brewing procedures.

• The perforated filter head with an aperture has an open design similar to sieves.

• The inlet tube is rolled up on the outer casing of the malt container/brewer device, which makes it possible to cool the wort in a cheap and efficient way before the fermentation phase. s follows, the invention is presented with the help of illustrations.
