Solution Overview

Problem

Dough processing times are prolonged due to the need for periods of rest to allow dough relaxation, which slows down the production of baked goods, as the conformation of gluten proteins changes, reducing dough resistance against deformation.

Innovation Solution

Applying an electromagnetic field to the dough during or after mechanical processing steps, such as kneading or shaping, to decrease resistance against deformation and increase extensibility, allowing for faster processing by reducing the time needed for dough relaxation, with the electromagnetic field applied for less than 30 seconds and the dough resting for less than 10 minutes.

VSEngineering Contradiction Analysis

1Ease of operation

If periods of rest are provided for dough relaxation between mechanical processing steps, then the resistance of the dough against deformation decreases and extensibility improves, but the processing time increases

Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent applies electromagnetic fields (electric or magnetic) to change the physical state of the dough, specifically targeting the gluten protein structure. By applying electric fields of 1-50 kV/m or magnetic fields of 0.01-10 T, the conformation of gluten proteins is modified, causing a decrease in resistance against deformation without requiring extended rest periods. This parameter change in the electromagnetic environment directly accelerates the relaxation process.

Solution Approach 2:

The patent replaces the traditional mechanical approach of prolonged resting periods with an electromagnetic field application system. Instead of relying on passive time-based relaxation, electromagnetic fields are applied through electrodes or magnets to actively modify the dough's rheological properties, substituting a time-intensive mechanical waiting process with a controlled electromagnetic treatment that achieves the same effect much faster.

Core Design Contradiction:

Solution Approach 1:

The patent segments the electromagnetic treatment into distinct modular components: electric field generation through electrodes, magnetic field generation through magnets, and control systems. This segmentation allows the complex electromagnetic treatment to be implemented as separate, manageable modules that can be integrated into existing dough processing lines without requiring complete system redesign.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The electromagnetic field application system serves multiple functions: it decreases resistance against deformation, improves extensibility, and can be applied at various stages of dough processing (kneading, shaping, dividing). The same basic electromagnetic apparatus can be configured for different field types (electric or magnetic) and applied to different dough products, providing universal functionality across multiple processing operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)
