Helical Flow Deflector for Foam-Free Carbonated Product Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow deflectors for filling carbonated products interfere with the vortex flow of the filling fluid, leading to foam formation and are often complex in design, requiring variable positioning and additional ducts for gas evacuation.
Innovation Solution
A compact flow deflector with a swirl body featuring a helical passage for the filling fluid and a coaxial, helically extending passage for gas evacuation, which are complementarily shaped to minimize interference and avoid additional ducts, using materials like stainless steel or titanium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a helical deflector with a transverse duct section is used for gas evacuation, then gas can be evacuated from the receptacle, but the transverse duct section disturbs the vortex motion of the filling fluid and increases foam formation
Solution Approach 1:
The duct is divided into two functional sections: a first section that extends centrally at the inlet for gas evacuation, and a second section that runs parallel to the valve body away from the inlet. This segmentation allows the duct to perform gas evacuation while minimizing interference with the vortex flow of the filling fluid.
Solution Approach 2:
The duct configuration transitions from a transverse section (perpendicular to the valve body) to a parallel section (aligned with the valve body axis). This dimensional change allows the duct to exit the receptacle in a direction that does not disturb the vortex motion, resolving the contradiction between gas evacuation and vortex flow preservation.
2Object-generated harmful factors
If deflectors are positioned at the connection area between the body and neck to achieve good deflection, then foam formation is reduced, but the deflector design becomes variable and complex to adapt to different receptacle shapes
Solution Approach 1:
The flow deflector is designed with a standardized configuration that can be used across different receptacle formats. The deflector includes a body portion and a neck portion with specific geometric relationships that provide universal applicability while maintaining effective deflection performance for various receptacle shapes.
Solution Approach 2:
The deflector design incorporates variable parameters such as the angle of the deflection surface and the dimensions of the body and neck portions. These parameters can be adjusted to optimize performance for different receptacle shapes and sizes, providing adaptability without requiring fundamentally different designs.
3Object-generated harmful factors
If a compact flow deflector with coaxial helical passages is used, then gas evacuation is achieved without disturbing vortex flow, but the structural simplicity must be maintained
Solution Approach 1:
The gas evacuation passage and the filling fluid passage are merged into a single coaxial helical structure. The deflector creates a unified flow path where both gases and filling fluid follow helical trajectories, eliminating the need for separate complex duct systems and reducing overall device complexity.
Solution Approach 2:
The deflector incorporates helical and curved surfaces that guide both the filling fluid and gas in smooth vortex motions. The curved geometry of the deflection surfaces and the helical passage configuration minimize turbulence and foam formation while maintaining a compact, simple structure.
