Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for carbonating beverages are inefficient, leading to significant waste of carbon dioxide gas, increased operational costs, and potential health hazards due to undissolved CO2 venting into the atmosphere, while also allowing oxygen into the carbonation tank, which can negatively impact beer quality and shelf life.
Innovation Solution
A system that automatically controls the carbonation process by supersaturating beer with CO2 in a separate tank and then injecting it into the carbonation tank, eliminating the need for a gas headspace and reducing operator input, which allows for consistent and faster carbonation with reduced CO2 usage and minimized oxygen introduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If CO2 gas is bubbled through the beer using diffusers, then the beer becomes carbonated, but a large amount of CO2 gas is wasted and vented into the atmosphere
Solution Approach 1:
The system pre-carbonates the beer in a carbonation tank before transferring to storage or dispensing vessels, ensuring CO2 is dissolved in advance rather than continuously bubbling during storage. This preliminary carbonation action eliminates ongoing CO2 waste while maintaining carbonation levels.
Solution Approach 2:
The invention introduces a CO2-saturated water solution as an intermediary medium. Instead of directly bubbling CO2 gas into the beer, the system uses CO2-saturated water to transfer CO2 to the beer, significantly improving dissolution efficiency and reducing gas waste.
2Reliability
If a gas headspace is maintained in the carbonation tank, then undissolved CO2 can be collected and vented, but oxygen from air can enter the tank and degrade beer quality
Solution Approach 1:
The system maintains an inert CO2 atmosphere in the carbonation tank by filling it with CO2 gas and maintaining positive pressure. This inert environment prevents oxygen from air from entering the tank and contaminating the beer, while still allowing undissolved CO2 to be collected and vented through the headspace.
Solution Approach 2:
The beer is pre-carbonated in the sealed carbonation tank before being transferred to storage or dispensing vessels. This preliminary carbonation action occurs in a controlled inert atmosphere, ensuring carbonation is achieved before any potential oxygen exposure during transfer.
3Quantity of substance
If CO2 is continuously added to maintain carbonation levels, then the beer remains carbonated, but operational costs increase and CO2 emissions increase
Solution Approach 1:
The system uses a pressure-regulated valve that automatically maintains the desired CO2 pressure in the carbonation tank without continuous operator intervention. Once the tank is pressurized to the set point, the system self-regulates to maintain carbonation levels, eliminating the need for continuous CO2 addition and reducing both costs and emissions.
Solution Approach 2:
The beer is pre-carbonated to the desired level before transfer, and the carbonation tank is sealed and pressure-regulated to maintain those levels. This preliminary carbonation and sealing action eliminates the need for continuous CO2 addition during storage and dispensing.
4Adaptability or versatility
If manual monitoring and adjustment of carbonation is performed, then the process can be flexible, but operator input increases and consistency decreases
Solution Approach 1:
The system incorporates pressure sensors and automated control valves that continuously monitor CO2 pressure in the carbonation tank and automatically adjust to maintain the desired set point. This feedback control mechanism provides consistent, repeatable carbonation levels without requiring manual monitoring or adjustment, while still allowing operators to change parameters for different beer styles.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly reduces CO2 waste and emissions, lowers operational costs, and ensures consistent beer quality by maintaining the desired CO2 concentration without increasing tank pressure, thus improving the carbonation process efficiency and reducing the carbon footprint.
Implementation Method 1
A system that automatically controls the carbonation process by supersaturating beer with CO2 in a separate tank and then injecting it into the carbonation tank
Implementation Method 2
The gas dissolves into the beer as the bubbles rise through the beer
Implementation Method 3
As the pressure of the gas and beer is increased, the beer can hold more dissolved CO2

AI summary
A system and method for carbonating a beverage is shown. The system includes a saturation tank having a gas head space of CO2, a carbonation tank, and a beverage supply system to pass the beverage between the saturation tank and the carbonation tank. A beverage supersaturated with CO2 from the head space is formed in the saturation tank. The supersaturated beverage is passed from the saturation tank to the carbonation tank. Once the amount of CO2 added to the beverage exceeds saturation, some of the CO2 escapes from solution from the beverage and the pressure in the carbonation tank increases. Once the pressure within the carbonation tank reaches a pre-defined pressure for the desired volume CO2/volume beverage, a pump supplying the beverage to the saturation tank is shut-off and the inlet and outlet valves of the carbonation tank are closed.
