Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional beer aging process is lengthy, which undercuts the shelf life of beer, increases production costs due to equipment bottlenecks, and poses contamination risks, necessitating a method to accelerate flavor transfer without compromising beer quality.
Innovation Solution
Applying ultrasound to the fermented beer to disrupt added materials, enhancing flavor transfer and reducing aging time from weeks or years to less than several hours, using ultrasonic transducers that generate frequencies between 20 kHz and 80 kHz, while maintaining the integrity of the beer and minimizing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional aging process is used to impart flavor to beer, then flavor transfer is achieved, but aging time is prolonged (weeks to years)
Solution Approach 1:
The patent applies ultrasonic vibration (mechanical vibration) to the beer during aging to accelerate flavor transfer from added materials. The ultrasonic waves create cavitation and micro-streaming effects that enhance mass transfer between the aging materials and beer, achieving traditional aging flavor profiles in significantly reduced time (hours instead of weeks/months).
Solution Approach 2:
The patent changes physical parameters of the aging process by introducing ultrasonic frequency (20-80 kHz) and intensity control. By adjusting ultrasonic parameters along with temperature and material contact conditions, the flavor extraction rate is dramatically increased, resolving the time-quality contradiction in beer aging.
2Manufacturing precision
If prolonged aging is used to enhance flavor, then flavor complexity increases, but equipment occupancy increases causing production bottlenecks
Solution Approach 1:
Ultrasonic vibration accelerates the flavor extraction process, allowing beer to achieve complex flavor profiles in hours rather than extended periods. This dramatically reduces occupancy time of aging equipment (barrels, vats), freeing them for continuous production cycles and eliminating the bottleneck effect on overall brewery productivity.
3Manufacturing precision
If extended aging period is used for flavor development, then flavor transfer is enhanced, but contamination risk increases
Solution Approach 1:
The ultrasonic field creates a controlled environment with intense localized mixing and reduced stasis periods where contaminants could develop. The rapid processing time (hours vs. weeks/months) minimizes the window for contamination events, while the cavitation effect may also have mild sanitizing properties, thereby reducing overall contamination risk while maintaining flavor transfer quality.
4Manufacturing precision
If traditional aging is used to impart flavor, then beer shelf life is maintained, but aging time extends beyond optimal shelf life
Solution Approach 1:
By using ultrasonic vibration to accelerate flavor extraction, the beer achieves its final flavor profile in hours rather than weeks or months. This allows the beer to reach its optimal consumption point much sooner, extending the period during which the beer maintains both its desired flavor characteristics and optimal shelf life, as it doesn't need to sit in storage for extended aging periods.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The ultrasound-based method significantly reduces aging time, ensuring flavor transfer without disrupting yeast cells or increasing contamination risks, resulting in a product comparable to traditionally aged beer in terms of flavor, while minimizing equipment occupancy and shelf life impact.
Implementation Method 1
generating ultrasound that travel into the fermented beer using the one or more ultrasonic transducers
Implementation Method 2
The ultrasound disrupts the materials present in the fermented beer, thereby causing particles from the materials to detach from the materials and mix with the beer

AI summary
A method for accelerating aging of beer in order to enhance one or more flavors that are exhibited by the beer; it includes providing in a recipient beer with one or more materials to impart flavor to the beer during an aging process, the recipient joined to one or more ultrasonic transducers; generating ultrasound that travel into the beer using the one or more ultrasonic transducers in order to disrupt the one or more materials contained in the beer, thereby imbuing the beer with one or more flavors corresponding to the one or more materials; and extracting the flavored beer from the recipient for bottling, whereby the bottled beer is carbonized.
