Retort Basket Latch and Roller Support for Reciprocation Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In retort sterilization processes, the reciprocating movement of product baskets creates gaps and vibrations due to momentum, making it difficult to maintain secure support and prevent lateral shifting, especially when multiple baskets are loaded end-to-end.
Innovation Solution
A retort system with a basket supporting assembly that includes a latch mechanism with an actuator, such as a bladder system, to maintain engagement with the baskets and reduce spacing between them, and a roller support system with transfer and support rollers to stabilize the baskets during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple product baskets are loaded end-to-end in the retort, then the productivity is improved by maximizing space utilization, but gaps and vibrations occur during reciprocation due to momentum causing baskets to compact against each other
Solution Approach 1:
The latch mechanism is activated before reciprocation begins to pre-compact the baskets and eliminate gaps. The actuator moves the latching part to engage with the baskets and progressively reduce spacing between them, so that when reciprocation starts, the baskets are already in a stable, gap-free arrangement that prevents vibration and impact during movement
2Reliability
If the basket support assembly is moved back and forth during sterilization, then the sterilization effectiveness is improved through enhanced heat distribution, but the momentum of the baskets creates impact forces and vibrations that can damage the system
Solution Approach 1:
The latch mechanism applies a pre-compacting force in the opposite direction of the reciprocating motion before movement begins. This preliminary anti-action counteracts the momentum that will occur during reciprocation, preventing the baskets from slamming against stops and reducing vibrations throughout the sterilization process
3Ease of operation
If roller supports are used to move the baskets during reciprocation, then the ease of operation is improved by facilitating smooth movement, but lateral shifting of the baskets becomes difficult to prevent
Solution Approach 1:
The roller support system is combined with lateral constraint features such as side rails or flanged rollers that prevent sideways movement. This merging allows the rollers to facilitate smooth forward and backward motion while simultaneously constraining lateral shifting, achieving both ease of operation and positional stability
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
The system effectively reduces gaps and vibrations by maintaining a compact arrangement of baskets during reciprocation, improving loading, unloading, and processing efficiency while preventing lateral shifting.
Implementation Method 1
an actuator that is operable to (i) move the latching part from the non-latching orientation to the latching orientation and (ii) maintain a bias of the latching part toward the latching orientation
Implementation Method 2
Supporting the baskets on roller supports during such movement

AI summary
A retort system for heating product to a specified temperature for sterilization is provided. The system includes a vessel having an associated heating system. A frame within the vessel for securing the baskets during reciprocation of the baskets may include a progressive latch mechanism. A roller arrangement for supporting baskets within the vessel may include both a plurality of transfer rollers and a plurality of support rollers.
