Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If re-treatment of semi-finished high fructose syrup is performed to reduce HMF content, then HMF content is reduced, but working procedures and costs increase
Solution Approach 1:
The patent applies preliminary action by optimizing ion exchange and mixed bed operations during the initial production process rather than performing re-treatment on semi-finished products. The system performs HMF reduction through controlled ion exchange (changing from double group to single group operation mode) and heat exchange procedures that lower feed temperature to the mixed bed column, preventing HMF formation and polymerization in the first place, thereby eliminating the need for additional re-treatment procedures.
2Object-affected harmful factors
If re-treatment of semi-finished high fructose syrup is performed to reduce HMF content, then HMF content is reduced, but production costs increase
Solution Approach 1:
The patent applies parameter changes by optimizing operational parameters including changing the ion exchange from double group to single group operation mode, controlling pH values, adjusting temperature parameters through heat exchange, and optimizing flow rates. These parameter optimizations enable HMF reduction during normal production without requiring additional energy-intensive re-treatment processes, thereby reducing production costs while achieving the desired HMF content reduction.
3Productivity
If high temperature conditions are applied during storage, then processing efficiency is improved, but polymerization reaction occurs causing yellowing and reduced service life
Solution Approach 1:
The patent applies preliminary anti-action by implementing measures during production to prevent polymerization reactions before they can occur during storage. The system uses optimized ion exchange and heat exchange procedures to control HMF content and prevent the formation of substances that would trigger polymerization at high temperatures. By addressing HMF reduction proactively during production rather than reactively during storage, the system prevents the chain reaction that leads to yellowing and service life reduction.
