Description

Technical Field

[0001] The utility model relates to the technical field of beer brewing, in particular to a wort oxygenation device for beer brewing. Background Art

[0002] The brewing of beer is inseparable from yeast. In order for the yeast in the pre-fermentation stage of beer to complete its proliferation, it is necessary that the wort contains sufficient oxygen. If the content does not meet the requirement, it will affect the normal reproduction of the yeast. In the beer brewing process, wort oxygenation is an opportunity to provide oxygen to the yeast. The yeast can consume the provided oxygen within a few hours, and there is no oxidative damage to the quality of the wort. Therefore, an oxygenator is often installed on the wort delivery pipeline to pass oxygen into the wort. In the prior art, a venturi tube is usually used to oxygenate the wort. Its structure is to increase the flow rate through a tube diameter contraction section, and air is sucked in through a nozzle. The wort forms a vortex in the tube diameter widening section, so that the wort is fully contacted with dispersed and dense air bubbles and mixed evenly. However, during the mixing process, oxygen will produce bubbles after entering the wort, and some bubbles are easily adsorbed on the inner wall of the pipe, which will affect the mixing of oxygen and wort.
