Polymeric Adsorbent for CIP Media Aromatic Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current CIP media systems fail to effectively remove non-polar aromatic substances like aldehydes, ketones, esters, phenols, anisoles, and heteroaromatics, leading to off-flavors in products and a shortened service life of CIP media, making it difficult to fill products with different taste intensities on the same bottling plant.
Innovation Solution
The use of crosslinked polyethylene as an adsorbing polymeric material for direct contact with CIP media to adsorb and reduce aromatic substances, ensuring they do not impair the taste of filled products, with the adsorbent material being used in amounts ranging from 2g/L to 200g/L.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If CIP media are reused multiple times, then cost efficiency improves, but aromatic substances accumulate and cause off-flavors in products
Solution Approach 1:
The patent extracts and removes aromatic substances from the CIP media through filtration and adsorption processes. The returning CIP media are treated to separate and eliminate the harmful aromatic compounds that cause off-flavors, allowing the media to be reused without contaminating subsequent products.
Solution Approach 2:
The patent introduces an intermediary treatment system between the CIP media circulation and the product filling process. This intermediary system includes filtration units and adsorption materials that mediate the interaction by capturing aromatic substances before they can contaminate products, enabling extended media reuse.
2Adaptability or versatility
If different taste intensity products are filled on the same bottling plant, then production versatility improves, but cross-contamination of flavors occurs
Solution Approach 1:
The patent removes aromatic substances from CIP media through filtration and adsorption, preventing these extracted contaminants from transferring between different product batches. This extraction process enables the system to handle diverse products with different taste intensities without cross-contamination.
Solution Approach 2:
The patent discards the harmful aromatic substances from the CIP media through adsorption onto polymeric materials while recovering and reusing the cleaned CIP media. This selective discarding of contaminants and recovery of the cleaning medium enables versatile product production without flavor cross-contamination.
3Reliability
If CIP media flow through product-carrying lines, then cleaning effectiveness improves, but aromatic substances are transported and stored in polymeric components
Solution Approach 1:
The patent extracts aromatic substances from the CIP media that have been circulating through the system. By removing these substances from the returning media, the patent prevents their accumulation in polymeric seals and components, maintaining cleaning effectiveness while avoiding contamination storage.
Solution Approach 2:
The patent introduces a filtration and adsorption intermediary system that processes the returning CIP media. This intermediary treatment prevents aromatic substances from being transported to and stored in polymeric components, while still allowing the CIP media to perform their cleaning function effectively.
