Receiving Chamber Spiral Flow for Sausage Strand Coating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for producing sausage strands from pasty masses face issues with uniform coating due to pressure fluctuations and varying viscosities of casing materials, leading to defects and potential strand breakage.
Innovation Solution
The receiving chamber is designed to impart a spiral movement to the casing material with both rotational and axial components, ensuring uniform pressure distribution and consistent coating thickness, regardless of the casing material's viscosity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the receiving chamber uses a conventional outlet design, then the device structure is simple, but pressure fluctuations occur causing non-uniform coating thickness
Solution Approach 1:
The receiving chamber is designed with a curved, annular cross-section that guides the casing material in a spiral flow path around the conveying line. This curved geometry naturally distributes pressure uniformly across the outlet circumference, eliminating the need for complex pressure control mechanisms while achieving uniform coating thickness.
Solution Approach 2:
The invention introduces a spiral flow dimension by arranging the inlet and outlet at different angular positions around the conveying line. The casing material flows through the receiving chamber in a helical path, adding a rotational component to the flow that ensures all regions of the outlet receive equal pressure and material distribution.
2Adaptability or versatility
If the receiving chamber processes casing materials with different viscosities, then the device has high adaptability, but pressure fluctuations and coating defects increase
Solution Approach 1:
The receiving chamber geometry is optimized to accommodate a wide range of viscosity parameters. The annular cross-section and spiral flow path create a pressure distribution pattern that remains stable across different material viscosities, allowing the same device to reliably process various casing materials from low to high viscosity without generating defects.
Solution Approach 2:
The receiving chamber is designed as a universal component that can handle different casing materials (collagen, alginate, and other natural or artificial casings) with varying viscosities. The spiral flow design and annular geometry provide consistent performance across material types, making the device adaptable to different production requirements while maintaining coating quality.
3Manufacturing precision
If the outlet is formed along the entire circumference, then the entire strand circumference is covered, but pressure distribution becomes uneven leading to defects
Solution Approach 1:
The annular, curved receiving chamber creates a spiral flow pattern that distributes pressure evenly around the entire outlet circumference. The curved geometry ensures that pressure builds up uniformly as material flows through the chamber, preventing localized high or low pressure zones that would cause coating defects or incomplete coverage.
