Solution Overview

Problem

There is a lack of commercially available defibrated products of fibrous vegetable protein that maintain sufficient fiber length, which are necessary to impart excellent texture to food and serve as a versatile cooking material.

Innovation Solution

The production method involves processing textured fibrous vegetable protein in a gap between two surfaces to achieve fibers with a number average length of 10 mm or more and a content of fibers with an aspect ratio of less than 5 being 80% or less, using a grinding device like a stone mill or rotary stone mill without blades.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If conventional processing methods are used to fibrillate fibrous vegetable protein, then the protein can be processed into textured forms, but the fiber length is excessively shortened and the fibers cannot be individualized while maintaining sufficient length

Engineering Contradiction:
Improvefiber lengthVSAvoiddifficulty of fibrillation
Core Design Contradiction:
Length of moving objectVSEase of manufacture

Solution Approach 1:

The patent changes the processing parameters by controlling the gap width between grinding surfaces (0.1-10 mm) and adjusting the relative speed between surfaces (10-1000 mm/s). These parameter changes enable fibrillation that individualizes fibers while maintaining length (10 mm or more), resolving the contradiction between fiber length preservation and fibrillation effectiveness.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the fibrous vegetable protein is processed to individualize fibers, then the texture of food can be improved, but the production efficiency decreases due to the complexity of maintaining fiber length

Engineering Contradiction:
Improvefiber individualizationVSAvoidproduction efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent replaces complex mechanical fibrillation systems with a simplified gap-based grinding mechanism. By using two surfaces with a controlled gap (0.1-10 mm) moving relative to each other, the system achieves fiber individualization without requiring complex blade mechanisms, thereby improving production efficiency while maintaining manufacturing precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of manufacture

If blade-based grinding devices are used to process textured vegetable protein, then the protein can be broken down, but the fibers are cut into excessively short pieces losing the fibrous structure

Engineering Contradiction:
Improveprocessing capabilityVSAvoidfibrous structure
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The patent extracts the blade component from the grinding device, using only two surfaces with a controlled gap. This extraction of the cutting element eliminates fiber cutting while maintaining processing capability, allowing the fibrous structure to be preserved through friction-based fibrillation rather than blade-based cutting.

Inventive Principle:
Principle #2Taking out (Extraction)
