Modified Cooking Surface Pockets for Selective Browning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveyorized and batch oven systems for baked products require the use of oil or release agents on cooking surfaces to achieve a selective browning effect, which can be costly and inefficient.
Innovation Solution
The cooking surfaces of oven systems are modified with a raised area and depressed area featuring a plurality of pockets arranged in a random pattern, allowing for a selective browning effect without the need for additional release agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If oil or release agent is applied to cooking surfaces to achieve selective browning effect, then the browning quality is improved, but the cost and efficiency deteriorate
Solution Approach 1:
The cooking surface is modified with localized depressed areas (pockets) that create selective contact zones between the batter and cooking surface. This local geometric variation produces different browning patterns in specific areas without requiring uniform application of release agents across the entire surface, thereby achieving quality browning effects while reducing material consumption.
Solution Approach 2:
The cooking surface geometry itself serves the function previously requiring external release agents. The depressed areas naturally control batter contact and heat transfer, enabling the cooking surface to self-regulate browning patterns without dependency on additional chemical substances, thus eliminating ongoing material costs.
2Manufacturing precision
If oil or release agent is used on cooking surfaces, then selective browning is achieved, but operational efficiency deteriorates
Solution Approach 1:
The cooking surface geometry inherently provides the selective browning function through its depressed area design, eliminating the need for manual or automated release agent application processes. This self-sufficient design streamlines operations by removing an entire process step, thereby improving productivity without sacrificing browning quality.
Solution Approach 2:
The function of achieving selective browning is extracted from the chemical domain (release agents) and transferred to the geometric domain (surface topology). By removing dependency on external substances and embedding the browning control function directly into the surface geometry, the system achieves both quality results and operational efficiency.
3Ease of manufacture
If conventional smooth cooking surfaces are used, then manufacturing simplicity is maintained, but browning pattern control deteriorates
Solution Approach 1:
Rather than making the entire cooking surface complex, only localized depressed areas are introduced into an otherwise simple base structure. This selective modification approach maintains ease of manufacture for the majority of the surface while providing precise browning control in specific regions where the pockets create differentiated contact zones.
Solution Approach 2:
The cooking surface is segmented into distinct functional zones: raised areas for uniform contact and depressed pockets for selective browning. This segmentation allows the simple base structure to be combined with localized complex features, balancing manufacturing ease with functional precision for pattern control.
