Multi-Layer Food Load Model for Precision Cooking Parameter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking systems lack the ability to precisely control the heating of multiple layers of a food load to achieve desired cooking parameters, as they do not account for varying heat absorption relationships between different layers, leading to inconsistent cooking results.
Innovation Solution
A cooking system with a controller that accesses a food load model comprising multiple layers with distinct heat absorption relationships, allowing for the calculation of a heat exchange model and the selective activation of heat sources to achieve uniform cooking parameters across each layer.

1Manufacturing precision
If a single-layer cooking model is used, then the device complexity is reduced, but the manufacturing precision of cooking parameters for multi-layer food is insufficient
Solution Approach 1:
The food load is divided into multiple layers (first layer, second layer, third layer) with distinct heat absorption relationships. Each layer is modeled separately with its own cooking parameters, allowing precise control of heating for different portions of the food load while maintaining manageable model complexity through systematic segmentation.
Solution Approach 2:
Different heat absorption relationships are assigned to different layers of the food load. The model accounts for varying thermal properties at different depths, enabling localized cooking parameter optimization for each layer rather than applying a uniform model to the entire food load.
2Productivity
If multiple heat sources are used, then the productivity of cooking process is improved, but the device complexity increases
Solution Approach 1:
Multiple heat sources (microwave, convection, steam) are combined into a single integrated heating apparatus controlled by one controller. The controller coordinates these heat sources using the multi-layer model to achieve efficient cooking while avoiding the complexity of multiple independent heating systems through unified control architecture.
Solution Approach 2:
The heating apparatus is designed to perform multiple cooking functions (microwave heating, convection heating, steam injection) within a single device. This multi-functional approach improves cooking productivity and versatility while maintaining a unified system structure that manages complexity through integrated control.
