Axial Gas Drying for Uniform Columnar Structure Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drying devices for columnar structures face issues of complex configuration, high electricity consumption, non-uniform drying due to radial airflow, and prolonged drying times, leading to increased manufacturing costs and uneven capsule thickness.
Innovation Solution
A drying device with feeding and discharge parts on an opposing surface facing the supporting surface, forming an axial airflow around columnar structures, and symmetrically disposed discharge parts to ensure uniform drying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If air flows in the radial direction of the capsules, then drying can be performed, but non-uniform drying occurs resulting in non-uniform capsule thickness
Solution Approach 1:
The patent inverts the conventional radial airflow direction and implements axial airflow through the capsule by positioning feeding and discharge parts at opposite ends of the molding pin, enabling uniform drying without compromising drying speed
Solution Approach 2:
The patent changes the airflow direction from radial (horizontal dimension) to axial (vertical dimension), creating a one-dimensional flow path through the capsule that ensures uniform drying throughout the capsule structure
2Manufacturing precision
If the flow rate of air is reduced to avoid non-uniform drying, then capsule thickness uniformity is improved, but drying time increases
Solution Approach 1:
Instead of reducing airflow rate to achieve uniformity, the patent inverts the airflow direction to axial flow, which naturally provides uniform distribution throughout the capsule while maintaining high drying speed
Solution Approach 2:
The patent changes the flow direction parameter from radial to axial, which fundamentally alters the drying pattern to achieve both uniformity and speed without needing to adjust flow rate
3Ease of manufacture
If conventional heating of pins is used, then drying can be performed, but the configuration becomes complex and electricity consumption increases
Solution Approach 1:
The patent extracts the heating function from the molding pin and relocates it to the airflow system, eliminating the need for heated pins and their associated complex configurations and high electricity consumption
Solution Approach 2:
The patent replaces the thermal conduction mechanism (heated pins) with a convective heating mechanism (hot airflow), simplifying the system configuration and reducing energy consumption
