Separate Gas Ducts for Foam-Resistant Beverage Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for preparing and dispensing carbonated refrigerated beverages often produce excessive foam, which can obstruct valves and lead to system failures and overpressure risks due to inadequate gas feeding and discharge systems.
Innovation Solution
The apparatus features separate feed and discharge ducts for pressurization gas, equipped with independent valve members to control gas flow, preventing foam from interfering with the system and maintaining tank pressure, thus ensuring reliable operation even with foam present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single duct system is used for feeding and discharging pressurization gas, then the device complexity is reduced, but the reliability deteriorates due to foam obstruction risk
Solution Approach 1:
The single duct system is segmented into separate feed and discharge ducts for pressurization gas. Each duct is equipped with its own valve member, allowing independent control. This segmentation prevents foam from obstructing both functions simultaneously and enables reliable operation even when foam is present in the tank.
2Reliability
If separate feed and discharge ducts with independent valve members are used, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The system is divided into separate feed and discharge ducts with independent valve members. This segmentation provides reliable foam management by preventing simultaneous obstruction of both functions, while maintaining a relatively simple overall structure suitable for commercial beverage preparation systems.
3Quantity of substance
If foam is allowed to rise in the tank, then the product volume is maximized, but the harmful factors increase due to valve obstruction and overpressure risk
Solution Approach 1:
By separating the feed and discharge functions into different ducts with independent valve control, the system allows foam to exist in the tank without causing obstruction. The discharge duct can be positioned or controlled to bypass foam layers, enabling maximum product storage while preventing harmful valve obstructions and overpressure conditions.
