Solution Overview
Problem
Existing fluidizing apparatuses for conditioning solid particles face challenges such as uniform gas flow issues, increased structural effort for gas regulation, and high production costs due to the need for segmentation and complex structural designs, which limit flexibility and increase production costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the distribution chamber is segmented into multiple sections with individual gas supply devices, then different conditioning conditions can be generated in individual sections, but the structural effort and production costs increase disproportionately
Solution Approach 1:
The air distribution plate features locally varying opening ratios in different radial zones, allowing different sections of the turbulence chamber to receive different amounts of gas without requiring physical segmentation or separate gas supply devices for each section. This creates locally optimized conditioning conditions while maintaining a unified, simple structure.
Solution Approach 2:
The opening ratios on the air distribution plate are designed to vary dynamically across the radial direction, with the degree of opening changing continuously from the center to the periphery. This dynamic variation in gas distribution enables flexible conditioning control without adding structural complexity or segmentation.
2Strength
If radial walls reach to the duct jacket above the height thereof, then the drying chamber is reduced within the turbulence chamber, but the structural stability is improved
Solution Approach 1:
The radial walls extend partially beyond the duct jacket height in specific zones where structural support is needed, rather than uniformly reaching above the entire duct jacket. This partial extension provides necessary structural stability while minimizing the reduction of the drying chamber volume, achieving a balance between strength and space utilization.
3Ease of operation
If a constant gas flow rate is maintained across the entire sieve bottom, then the system is simple to operate, but the conditioning efficiency varies for particles at different positions
Solution Approach 1:
The air distribution plate incorporates locally adapted opening ratios that vary by radial position, with larger openings in certain zones and smaller openings in others. This local differentiation ensures that particles at different positions within the turbulence chamber receive appropriate gas flow rates for optimal fluidization and conditioning, improving uniformity without complicating operation.
