Engineering Contradiction Analysis
1Measurement precision
If conventional industrial milling operations are used to predict wheat milling value, then accurate milling yield prediction is achieved, but the process becomes complex and time-consuming
Solution Approach 1:
The conventional complex milling process is segmented into a representative simplified sequence: grinding → first sieving (coarse separation) → second sieving (fine separation). This segmentation maintains the essential functional stages needed for accurate milling value prediction while eliminating redundant operations, achieving both accuracy and simplicity
Solution Approach 2:
The invention extracts only the critical operations from the full industrial milling process that are necessary for predicting milling value. By taking out and retaining only the essential grinding and sieving stages, the method achieves accurate prediction with a simplified procedure that uses significantly fewer operations
2Measurement precision
If conventional industrial milling operations are used to predict wheat milling value, then accurate milling yield prediction is achieved, but the process becomes time-consuming
Solution Approach 1:
The milling prediction process is segmented into a streamlined sequence of essential stages only, eliminating time-consuming redundant operations. The three-stage process (grinding, coarse sieving, fine sieving) maintains prediction accuracy while reducing total operation time compared to conventional multi-stage industrial milling
Solution Approach 2:
The invention extracts and retains only the critical time-consuming operations that contribute to accurate milling value prediction. By removing unnecessary intermediate steps and focusing on essential grinding and sieving operations, the method achieves both accuracy and time efficiency
3Ease of operation
If simplified laboratory-type equipment is used, then operational simplicity is achieved, but the flour characteristics may differ from industrial mill output
Solution Approach 1:
The invention adjusts key process parameters in the simplified laboratory procedure to match industrial mill conditions. By carefully controlling grinding intensity, sieving mesh sizes, and operational sequences, the method produces flour with characteristics comparable to industrial output while maintaining laboratory equipment simplicity
Solution Approach 2:
The simplified three-stage process serves multiple functions: it predicts milling value, produces representative flour samples, and maintains quality comparability to industrial output. This multi-functional approach allows laboratory equipment to achieve both simplicity and manufacturing precision
