Cover Element With Filter For Degassing Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for degassing and gassing containers, particularly unsealed containers filled with products like foodstuffs, face challenges in maintaining process quality due to product loss and contamination from suctioned particles during the degassing and gassing processes.
Innovation Solution
A device and method utilizing a cover element with adjustable openings and a filter element to minimize product loss and contamination, where the cover element is designed to fit sealingly over the container edge or into its interior, with the filter element being cleaned during the gassing process to prevent particle deposition and contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the opening dimension of the cover element is reduced to minimize product loss, then product loss is reduced, but gas exchange efficiency deteriorates
Solution Approach 1:
The cover element is divided into multiple segments or sections with individual openings, allowing the total opening area to be optimized for gas exchange while each individual opening remains small enough to minimize product loss. This segmentation enables simultaneous achievement of both requirements.
Solution Approach 2:
Different regions of the cover element have different opening characteristics - some areas have smaller openings to prevent product loss while other areas have larger openings or different configurations to maintain gas exchange efficiency. The local quality varies across the cover surface to balance both functions.
2Object-affected harmful factors
If the opening dimension of the cover element is reduced to prevent contamination, then contamination is reduced, but gas exchange efficiency deteriorates
Solution Approach 1:
A filter element is introduced as an intermediary component between the container interior and the external environment. This filter allows gas molecules to pass through while blocking larger product particles, thus enabling gas exchange efficiency while preventing contamination of the chamber with suctioned particles.
Solution Approach 2:
The filter element utilizes porous material structure with controlled pore sizes that permit gas flow while retaining larger particles. The porosity is optimized to balance gas exchange requirements with particle filtration, resolving the contradiction between contamination prevention and gas exchange efficiency.
3Object-affected harmful factors
If a filter element is added to capture particles, then contamination is prevented, but device complexity increases
Solution Approach 1:
The filter element is merged with the cover element structure, integrating the filtration function into the existing cover design rather than adding a completely separate component. This integration minimizes the increase in device complexity while achieving contamination prevention.
Solution Approach 2:
The cover element is designed to serve multiple functions simultaneously: sealing the container, enabling gas exchange, and supporting the filter element for particle capture. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity.

Function Achieved in This Case
The solution effectively reduces product loss and contamination by minimizing the opening size for gas exchange and using a filter element to capture and clean particles, ensuring a high degree of process quality during degassing and gassing operations.
Implementation Method 1
a filter element is provided at the at least one opening of the cover element. The filter element is configured for example as a lattice or fabric, in particular as a metal lattice or fabric.
