Frozen Dough Direct-to-Oven Baking via Pressure Differential
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional frozen dough processes require thawing, proofing, and baking steps, which are time-consuming and costly, and do not produce bread-like products with desired flavor and crumb structure, while existing solutions fail to create a product that can be directly baked from the freezer to the oven.
Innovation Solution
A frozen dough method involving flour, yeast, emulsifiers, and stabilizers, with a gluten content of 10-20% and yeast levels up to 14%, subjected to pressure differentials to create gas nucleation sites and restructure the dough matrix, allowing direct oven baking without thawing or proofing, using a combination of heating modes like convection, microwave, and infrared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frozen dough is thawed in a retarder and proofed before baking, then the bread achieves good organoleptic quality, but the process requires multiple equipment (freezer, retarder, proofer, oven) and qualified bakers, increasing operational complexity and cost
Solution Approach 1:
The dough is pre-proofed before freezing, so that the proofing action is completed in advance. This eliminates the need for a separate proofer in the bakery, as the dough arrives already proofed and ready for baking. The preliminary proofing action is performed during manufacturing rather than at the point of use.
Solution Approach 2:
The patent combines the freezer and oven into a single operational workflow, eliminating the need for separate retarder and proofer equipment. The frozen dough is transferred directly from storage freezer to baking oven, merging multiple processing steps into a simplified two-step process that reduces equipment complexity while maintaining product quality.
2Reliability
If frozen dough is thawed for 2-16 hours before baking, then the dough can be baked, but the bakery must presume product needs 3 hours before baking, reducing productivity and increasing storage space requirements
Solution Approach 1:
The dough is pre-proofed before freezing, so that the time-consuming proofing step is completed in advance during manufacturing. This eliminates the need for lengthy thawing and proofing periods in the bakery, allowing dough to be baked immediately upon removal from the freezer, thus improving productivity and eliminating the need for advance production planning.
3Device complexity
If lamination and chemical leavening systems are used to create freezer-to-oven products, then the process is simplified, but the product lacks bread-like flavor and crumb structure
Solution Approach 1:
The patent changes the yeast concentration parameter to 0.5-2.0% (higher than traditional formulations) and adjusts the proofing time parameter to 30-120 minutes before freezing. These parameter changes enable the dough to develop sufficient gas structure and flavor during pre-proofing, allowing it to be baked directly from frozen while maintaining authentic bread-like quality without requiring lamination or chemical leaveners.
4Reliability
If yeast concentration is increased to 0.5-2.0% and dough is pre-proofed for 30-120 minutes before freezing, then the dough achieves sufficient gas structure for direct-to-oven baking, but the formulation complexity increases
Solution Approach 1:
The patent optimizes the yeast concentration parameter to a specific range (0.5-2.0%) and the proofing time parameter (30-120 minutes) to achieve the desired gas structure. These controlled parameter changes provide a systematic approach that simplifies formulation by relying on quantitative optimization rather than complex ingredient combinations, making the process easier to control and replicate.
