Beer Tapping Device High CO2 Foaming Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tapping devices are unable to pour draught beer with high CO2 content, obtained through refermentation, in a quality manner due to excessive foaming issues, resulting in a difference in taste between refermented bottled and non-refermented draught beer.
Innovation Solution
A tapping device with a tapping line of specific dimensions (1.8-2.4m in length and 2.5-3.5mm internal diameter) and a cooling compartment set to 3-5°C, along with a pressure line for external CO2 regulation, ensures quality pouring of beer with high CO2 content by maintaining equilibrium and preventing excessive foaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If beer is refermented in the barrel to increase CO2 content, then the beer quality and taste are improved, but excessive foaming occurs during pouring
Solution Approach 1:
The beer is cooled to -5°C before pouring to pre-condition the beer and suppress foaming during the pouring process. This preliminary cooling action allows the beer to be poured with high CO2 content without excessive foaming
Solution Approach 2:
The temperature parameter is changed to -5°C, which is below the normal serving temperature. This parameter change suppresses the foaming tendency of high CO2 beer while maintaining the carbonation level, allowing quality draught beer with high CO2 content to be poured
2Stress or pressure
If external CO2 is added to maintain equilibrium pressure, then the beer can be forced out of the barrel, but the natural CO2 balance is disrupted
Solution Approach 1:
The system uses the beer's own CO2 pressure to force the beer out of the barrel, eliminating the need for external CO2 addition. The beer self-regulates its pressure and flow, maintaining natural CO2 balance while achieving proper dispensing
