Modular Twisted Stirring Rod for Food Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stirring rods in food processors are integrally formed and sealed, leading to excessive pressure on food materials, causing deformation and inadequacy in handling materials with varying densities, especially when used in tanks of different depths.
Innovation Solution
The stirring rod is assembled from multiple units with twisted, arc-shaped blades that form a non-sealed spiral blade with notches, allowing for adjustable arc lengths and angles to accommodate different food densities and tank depths, and an assembly rod connects the units for stable rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional integrally formed stirring rods with sealed spiral contours are used, then the stirring rod can be manufactured with simple structure, but the food materials are subjected to great pressure and squashed
Solution Approach 1:
The stirring rod is divided into multiple assembled stirring units that can be connected in series, creating a modular structure. Each unit contains individual stirring blades with notches, replacing the conventional sealed spiral contour. This segmentation reduces the continuous pushing force on food materials while maintaining manufacturing simplicity through standardized modular components.
2Device complexity
If conventional integrally formed stirring rods are used, then the structure is simple and unified, but the stirring rod cannot be adapted to tanks of different depths or food materials with varying densities
Solution Approach 1:
The stirring rod consists of multiple assembled stirring units connected in series along the axial direction. These modular units can be configured in different quantities and arrangements to adapt to tanks of various depths and food materials with different densities, while maintaining relatively simple individual unit structures.
Solution Approach 2:
The stirring blade is designed with a twist angle relative to the radial direction, creating a dynamic spiral contour that can be adjusted by changing the twist angle or the number of assembled units. This allows adaptation to different operational conditions without increasing the fundamental structural complexity.
3Reliability
If conventional sealed spiral contour stirring blades are used, then the stirring rod maintains continuous contact with food materials, but the blades become deformed and crushed under excessive pressure
Solution Approach 1:
The sealed spiral contour is divided into multiple discrete stirring blades with notches, each forming a separate segment. This segmentation reduces the continuous pushing force on any single blade, preventing deformation and crushing while maintaining reliable stirring contact through the series arrangement of multiple blades.
Solution Approach 2:
Notches are introduced at specific locations on the stirring blades to create localized pressure relief zones. This allows the blades to maintain contact with food materials for reliable stirring while reducing the overall pressure and preventing deformation through localized structural modification.
