Solution Overview

Problem

Fermentation products often have inconsistent color due to varying fermentation conditions, leading to color variations and increased costs when using uniform decolorization methods, and excessive decolorization can further exacerbate these issues.

Innovation Solution

A decolorization process that adjusts the intensity of adsorbent use based on the color value and purity of the fermentation process liquid, using activated carbon and other adsorbents like clay minerals, silica gel, and polymer resins, to maintain consistent color quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a consistent decolorization method is applied to all fermentation products, then color uniformity is improved, but production cost increases due to excessive adsorbent use

Engineering Contradiction:
Improvecolor uniformityVSAvoidadsorbent amount
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent implements a dynamic decolorization method where the adsorbent dosage is adjusted based on the initial color value of each fermentation batch. Instead of using a fixed amount of adsorbent for all batches, the method calculates the required adsorbent quantity according to the specific color characteristics of each fermentation liquid, thereby achieving color uniformity without excessive adsorbent consumption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of adsorbent dosage from a constant value to a variable value that depends on the initial color value of the fermentation liquid. By establishing a relationship between initial color value and required adsorbent amount, the method optimizes the decolorization process to use only the necessary adsorbent quantity for each specific batch.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If excessive decolorization is applied to prevent color variation, then color consistency is improved, but product quality deteriorates due to over-processing

Engineering Contradiction:
Improvecolor consistencyVSAvoidproduct quality
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent applies partial decolorization rather than excessive decolorization to all batches. By calculating the precise adsorbent dosage needed based on initial color values, the method achieves sufficient color consistency without over-processing, thereby maintaining product quality and avoiding the negative effects of excessive decolorization.

Inventive Principle:
Principle #16Partial or excessive action

3Manufacturing precision

If adsorbent amount is increased to handle high color value fermentation liquids, then decolorization effectiveness is improved, but production cost increases

Engineering Contradiction:
Improvedecolorization effectivenessVSAvoidadsorbent consumption
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent implements a feedback mechanism where the initial color value of the fermentation liquid is measured and used to determine the appropriate adsorbent dosage. This feedback loop ensures that each batch receives the precise amount of adsorbent needed for effective decolorization, avoiding both insufficient and excessive adsorbent use.

Inventive Principle:
Principle #23Feedback
