Sausage Throttling Axis Alignment to Prevent Casing Rupture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sausage manufacturing devices often experience hose rupture due to excessive stress during the throttling process, leading to production cessation, lengthy cleaning, and significant production losses, especially when using natural casings which are more fragile than artificial ones.
Innovation Solution
A sausage manufacturing device with a throttling system that constrains the hose around an axis parallel to the storage axis, reducing the risk of rupture by applying constriction closer to the storage axis, eliminating the need for an ejector for sausage evacuation, and simplifying the device's design and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a moving part is used to drive the casing in the throttling system, then the crimping operation can be performed, but significant stresses are exerted on the casing which can lead to rupture
Solution Approach 1:
Instead of moving the throttling arms toward a fixed cradle, the invention inverts the motion by making the cradle movable and the throttling arms fixed. This reversal changes the stress distribution from compressive forces on the casing to a more gentle guiding action, eliminating rupture while maintaining crimping capability
Solution Approach 2:
The movable cradle acts as an intermediary element that receives the casing and guides it through the fixed throttling arms. This mediator absorbs the mechanical interaction, allowing the casing to be positioned and crimped without direct stress from the throttling mechanism
2Ease of operation
If an ejector is added to lift sausages to discharge means, then sausage evacuation is enabled, but the device complexity increases and additional cleaning requirements arise
Solution Approach 1:
The invention removes the ejector mechanism entirely from the system. By repositioning the discharge means to receive sausages directly at the lower level where they exit the throttling system, the complex lifting and evacuation mechanism is extracted, simplifying the device while maintaining full functionality
Solution Approach 2:
The discharge means are positioned at the same level as the sausage exit from the throttling system, creating an equipotential arrangement where sausages can be discharged without requiring additional lifting or mechanical assistance

AI summary
The invention relates to a device (1) for making sausages, comprising a sausage casing (B) containing a food product (P) and sealed at the two ends thereof. Said device (1) comprises a means (2) for storing a sausage casing (B) while waiting for it to be filled with the food product (P), said storage means (2) extending along an axis (X), as well as a means (3) for conveying the food product (P) with a view to filling the sausage casing (B) with said food product (P), and at least one system (6) for constricting a portion of the sausage casing (B) filled with food product (P). Said device (1) is characterised in that the at least one constriction system (6) is configured to constrict the sausage casing (B) about an axis (X') which is at least parallel to the axis (X) along which the means (2) for storing the sausage casing (B) extends, and also passes through the end space (21).
