Carbonated Beverage Bottling Without Pressurizing or Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for preparing carbonated beverages often result in temperature and saturated vapor pressure changes, leading to bubble overflow and carbon dioxide evaporation when introducing carbon dioxide into beverages, necessitating temperature reduction or high pressure, which limits container size and efficiency.
Innovation Solution
A method involving placing a beverage composition at 10-30°C in a container and introducing solid or liquid carbon dioxide at −78.5 to −5°C, followed by immediate sealing to maintain minimal temperature and vapor pressure changes, allowing high carbon dioxide content without bubble overflow or evaporation, and enabling containers to be filled to the lid without excessive pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If carbon dioxide is introduced into beverage at normal temperature, then carbon dioxide dissolves in beverage, but temperature and saturated vapor pressure change causing bubble overflow and carbon dioxide evaporation
Solution Approach 1:
The beverage is pre-cooled to a specific temperature range (0°C to 10°C) before introducing carbon dioxide. This preliminary temperature adjustment ensures that when CO2 is introduced, the beverage maintains stable temperature and vapor pressure, preventing bubble overflow and CO2 evaporation while maximizing dissolution efficiency.
2Quantity of substance
If temperature is lowered to keep carbon dioxide dissolved, then carbon dioxide remains in beverage, but container size is limited and efficiency decreases
Solution Approach 1:
The invention optimizes the beverage temperature to a specific range (0°C to 10°C) rather than using extremely low temperatures. This parameter optimization maintains sufficient carbon dioxide dissolution while avoiding the need for oversized containers and maintaining production efficiency. The precise temperature control achieves the balance between dissolution capacity and practical container dimensions.

AI summary
Disclosed is a method for bottling a carbonated beverage in a container without causing overflow of the carbonated beverage or evaporation of carbon dioxide, the method including: placing a beverage composition without carbon dioxide in the container; introducing solid or liquid carbon dioxide to the beverage composition in the container to delay a change of vapor pressure in the container; and sealing the container before the introduced solid or liquid carbon dioxide is dissolved in the beverage composition, wherein a part of the introduced solid or liquid carbon dioxide in the sealed container becomes gas and the rest of the introduced solid or liquid carbon dioxide is dissolved in the beverage composition by pressure of the gas from the part of the introduced solid or liquid carbon dioxide without providing additional beverage composition, carbon dioxide and pressure in the container after sealing the container.
