Induction Heating Arrangement for Baking Ring with Roller Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baking devices using induction heating suffer from uneven heating of the rotating ring, leading to fluctuations in the quality of baked products due to manufacturing tolerances and varying distances between the inductor and the ring.
Innovation Solution
The heating arrangement is supported on the ring via rotatably mounted rollers, allowing for adjustable positioning to maintain a constant gap and ensure even heating, with a mechanism to adjust the position of the inductors relative to the ring, ensuring consistent heating across the ring's surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If induction heating is used to heat the rotating ring, then heating efficiency is improved, but heating uniformity deteriorates due to manufacturing tolerances and varying distances between inductor and ring
Solution Approach 1:
The heating arrangement is made movable relative to the machine frame, allowing it to follow the course of the rotating ring. This dynamic positioning compensates for manufacturing tolerances and maintains optimal heating distance throughout the rotation cycle, resolving the contradiction between heating efficiency and heating uniformity.
Solution Approach 2:
The heating arrangement is positioned using rollers that contact the ring surface, providing mechanical feedback to maintain constant spacing. This feedback mechanism ensures uniform heating by continuously adjusting the inductor position based on the actual ring geometry, eliminating the effects of manufacturing tolerances.
2Device complexity
If the heating arrangement is fixed relative to the machine frame, then device complexity is reduced, but heating uniformity deteriorates due to the rotating motion of the ring
Solution Approach 1:
The heating arrangement transitions from a fixed position to a movable position that follows the rotating ring. This dynamic configuration maintains constant distance between the inductor and ring surface throughout rotation, ensuring uniform heating without requiring complex active control systems.
Solution Approach 2:
Rollers serve as an intermediary element between the heating arrangement and the rotating ring. These rollers transmit the rotational motion and maintain optimal spacing, simplifying the positioning mechanism while ensuring heating uniformity through passive geometric constraint.
