Description

Technical Field

[0001] The utility model relates to the field of beer brewing, in particular to a beer dissolved oxygen detection device. Background Art

[0002] During the brewing and storage process of beer, the dissolved oxygen content is an important parameter, which has a great impact on the quality and taste of beer. Dissolved oxygen can cause beer to have undesirable flavors, such as oxidation, rancidity, bitterness, etc. Excessive dissolved oxygen can cause beer to lose flavor stability and become a waste product of germination. The dissolved oxygen in beer will react with the residual enzymes in the malt to produce irreversible oxidation. This may cause the beer to taste lighter, darker, and reduce the taste of the body. By controlling the dissolved oxygen content, the freshness and shelf life of beer can be extended. Yeast needs dissolved oxygen to maintain its health and metabolic activity during the fermentation process. The appropriate dissolved oxygen content is conducive to the reproduction and fermentation efficiency of yeast, as well as the production of good yeast aroma. Dissolved oxygen may cause suspended matter precipitation and amino acid degradation in beer. By controlling the dissolved oxygen content, the clarity of beer can be improved and unnecessary particulate matter can be avoided. Therefore, by detecting and controlling the dissolved oxygen content in beer, the quality and taste of beer can be ensured to be stable, its shelf life can be extended, and the health of yeast can be maintained.

And the flow of beer can be controlled by the solenoid valve 1 on the pipeline between the beer filter and the sake tank, directly preventing the beer with excessive dissolved oxygen from entering the sake tank at the source, reducing the loss of beer brewing. In addition, the design principle of the utility model is reliable, the structure is simple, and it has a very broad application prospect.
