Dual Casing Brake Filling Device for Air Bubble Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for filling pasty substances into casings, such as sausage casings, often result in air bubbles forming due to the difficulty in removing air effectively, leading to inefficient filling and potential contamination or leakage.
Innovation Solution
A device with a dual casing brake system, where the second casing brake is arranged to work in conjunction with the first, allowing for air to be sucked out via a vacuum tube, eliminating the need for a caliber ring and simplifying the handling process, ensuring the casing is sealed and air-free.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a vacuum tube with a caliber ring is used to remove air under the casing, then air removal effectiveness is improved, but handling complexity and time consumption increase significantly
Solution Approach 1:
The device separates the vacuum generation function (vacuum tube) from the casing sealing function (casing brake), allowing the casing brake to be pushed over the filling tube independently while the vacuum tube remains stationary. This segmentation eliminates the need to repeatedly assemble and disassemble caliber rings, significantly reducing handling complexity while maintaining effective air removal capability.
Solution Approach 2:
The patent introduces a stationary vacuum tube as an intermediary component that works in conjunction with the movable casing brake. The vacuum tube provides the vacuum function while the casing brake provides the sealing function, allowing these two functions to be performed simultaneously without interfering with each other's operation and simplifying the overall handling process.
2Object-affected harmful factors
If tipped casings with small holes are used to allow air escape, then air removal is improved, but sterility is compromised and mass leakage occurs
Solution Approach 1:
The device applies vacuum pressure in advance during the filling process to actively remove air from under the casing before the filling is complete. This preliminary air removal action eliminates the need for post-filling air escape mechanisms like tipped casings, thereby maintaining sterility and preventing mass leakage while still achieving effective air removal.
3Reliability
If manual pulling of the casing over the caliber ring is performed, then sealing is achieved, but the casing is damaged and handling time increases
Solution Approach 1:
The patent replaces the manual mechanical action of pulling the casing over the caliber ring with an automated system where the casing brake is pushed over the filling tube while vacuum is applied. This substitution eliminates the need for manual handling, protects the casing from damage, and significantly increases filling speed and productivity.
Applied Scientific Principles
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 solution effectively prevents air bubbles from forming under the casing, ensuring a complete and sterile filling process with reduced handling complexity and protection of the sausage casing.
Implementation Method 1
If the vacuum is now applied to the vacuum tube, the air under the casing between the caliber ring and the casing brake can be sucked out
Implementation Method 2
the air under the casing between the caliber ring and the casing brake can be sucked out

AI summary
The device has a filling pipe (1) through which a pasty mass (10) is pushed in a wrapping (8b). A skin brake (7) is provided, which is arranged in an output direction (A) of another skin brake (6), where the wrapping presses toward the filling pipe. A system is provided for suction of air under the wrapping between the two skin brakes. An independent claim is included for a method for filling pasty mass into a wrapping.
