Rolling Mandrel Temperature Control for Wafer Rolls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ring baking machines struggle to introduce temperature-sensitive masses into wafer rolls without compromising their temperature, due to heat transfer from the hot wafer strips to the rolling mandrel, making it difficult to maintain the desired temperature of the filling within the rolls.
Innovation Solution
A winding device with a temperature-controlled rolling mandrel featuring a cylindrical winding wall and a temperature control channel that extends from the supported section to the projecting section and back, allowing for precise temperature management and preventing heat transfer to the wafer rolls, ensuring the mass is introduced at the correct temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the rolling mandrel is used to wind up hot wafer strips, then the wafer rolls are formed continuously, but heat is transferred from the wafer strip to the rolling mandrel causing temperature-sensitive masses to deteriorate
Solution Approach 1:
A temperature control medium is introduced as an intermediary substance that flows through channels in the rolling mandrel, acting as a thermal mediator to absorb or supply heat between the wafer strip and the mandrel structure, thereby controlling the mandrel temperature independently
Solution Approach 2:
The temperature parameter of the rolling mandrel is actively changed and controlled by circulating a temperature control medium through integrated channels, allowing the mandrel temperature to be adjusted to match the required mass introduction temperature
2Quantity of substance
If a mass channel with larger diameter is arranged centrally in the rolling mandrel, then mass can be introduced into the wafer rolls, but the mass channel bears on the outer wall of the rolling mandrel making temperature control difficult
Solution Approach 1:
The temperature control channels are nested within the rolling mandrel structure, with the mass channel and temperature control channels arranged concentrically or adjacently within the same mandrel body, allowing both functions to coexist without interfering with each other
Solution Approach 2:
The rolling mandrel is segmented into functional zones with separate channels for mass introduction and temperature control, allowing independent optimization of each function's performance
