Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sugar beet processing systems face issues with pulp plugging extraction systems due to non-uniform cossette sizes, leading to thermal instability and reduced sucrose extraction efficiency, as well as increased energy consumption and maintenance costs in drying and pelletizing processes.
Innovation Solution
A pulp optimizer apparatus with counter-rotating cutting shaft assemblies and blades is introduced to uniformly size sugar beet cossettes, utilizing gear motors and sensors to adjust rotation speeds based on pulp volume, ensuring consistent pulp size and reducing moisture content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional slicing methods are used to produce cossettes, then the extraction system can operate, but the non-uniform cossette sizes cause thermal instability and plug the extraction systems
Solution Approach 1:
The slicing mechanism is divided into multiple cutting shafts with blades arranged in specific patterns, allowing differential cutting action that produces uniform cossette sizes while maintaining continuous operation of the extraction system
Solution Approach 2:
The cutting shafts rotate at different speeds and directions (interlaced counter-rotation), creating dynamic cutting action that adapts to varying beet root dimensions and produces consistent cossette uniformity throughout the extraction process
2Productivity
If cossettes are made smaller to improve extraction, then sucrose extraction efficiency increases, but energy consumption for drying and pelletizing increases
Solution Approach 1:
The device optimizes cossette size parameters through controlled cutting depths and blade configurations, achieving the ideal size range that balances extraction efficiency with subsequent processing energy requirements, thereby resolving the trade-off between productivity and energy consumption
3Reliability
If formaldehyde is dosed to limit thermophilic bacterial action, then sugar preservation improves, but the process becomes more complex and costly
Solution Approach 1:
The patent extracts and removes the chemical preservation step (formaldehyde dosing) from the process, relying instead on physical control of cossette size and thermal processing parameters to achieve sugar preservation, thereby simplifying the overall process while maintaining reliability
