Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of beer production, and more specifically, to a deoxygenated water efficient carbon dioxide adding system. Background Art
[0002] At present, in the process of producing beer, it is necessary to prepare deoxygenated water, and then mix it with the fermentation liquid in proportion to make the sake required for filling. However, the prepared deoxygenated water contains about 0.30% carbon dioxide, and it is necessary to add carbon dioxide to the prepared deoxygenated water to avoid the low proportion of carbon dioxide in the deoxygenated water. When a large amount of carbon dioxide is added during the dilution of the fermentation liquid, the carbon dioxide cannot be quickly integrated into the proportioning liquid, and a large number of bubbles are generated, which affects the accuracy of the measurement of the dilution ratio of carbon dioxide content. It will cause the following two situations to occur: First, when the carbon dioxide content is insufficient, the foaming of the beer will be reduced, the stimulation of carbon dioxide is too slight, the taste is bland, and the beer will lose its due characteristics; second, when the carbon dioxide content is too high, the killing power is too strong and the unique flavor of the beer, such as fragrance, bitterness, etc., will be diluted, and it will also cause the phenomenon of beer foam and easy explosion of bottles.
[0003] In the traditional method of preparing deoxygenated water, carbon dioxide is added to the outlet pipe before the deoxygenated water enters the tank to increase the carbon dioxide content of the deoxygenated water to 0.45%-0.55%. Since the outlet pipe has no pressure and the bubbles are large, the proportion of carbon dioxide dissolved in the deoxygenated water is low, about 30%, resulting in a large amount of carbon dioxide that cannot be dissolved in the deoxygenated water being discharged after entering the tank, causing production waste.

[0012] Beneficial Effects

[0020] By using the chilled thin plate cooler 4, the carbon dioxide is caused to expand and contract due to the drop in high-temperature deoxygenated water (78°C) to low-temperature deoxygenated water (3°C), and the narrow space inside the chilled thin plate cooler 4 squeezes the carbon dioxide from large bubbles into small bubbles.
