Solution Overview

Problem

Conventional methods for producing high-test molasses using mineral acids result in sugar loss, corrosion, low conversion efficiency, and caramelization, leading to a darker product with shorter shelf life and higher costs.

Innovation Solution

A method employing mild methane sulphonic acid for partial inversion of sugarcane syrup, which reduces sugar loss, avoids corrosion, and improves conversion efficiency, using reaction parameters like 0.1-1.0% acid concentration and 75-95°C temperature for 1-4 hours.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional mineral acids (H2SO4, HCl) are used for sucrose inversion, then inversion efficiency is achieved, but sugar loss increases and corrosion occurs

Engineering Contradiction:
Improveinversion efficiencyVSAvoidsugar loss
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The patent changes the chemical parameter by replacing strong mineral acids with mild organic acids (oxalic acid, citric acid, or lactic acid at 0.1-1.0% concentration). This parameter change maintains inversion efficiency while reducing sugar loss from 3-5% to minimal levels, and eliminates corrosion issues associated with strong acids

Inventive Principle:
Principle #35Parameter changes

2Productivity

If high temperature treatment is applied for sucrose inversion, then inversion rate increases, but caramelization occurs causing darker color

Engineering Contradiction:
Improveinversion rateVSAvoidproduct color quality
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The patent changes the temperature parameter from conventional high temperature (90-100°C) to mild temperature (75-95°C range, preferably 80-90°C). This temperature optimization maintains adequate inversion rate while preventing excessive caramelization, resulting in lighter colored high-test molasses with improved product quality

Inventive Principle:
Principle #35Parameter changes

3Speed

If strong acid and high temperature are used for inversion, then conversion speed increases, but sugar degradation increases

Engineering Contradiction:
Improveconversion speedVSAvoidsugar degradation
Core Design Contradiction:
SpeedVSLoss of substance

Solution Approach 1:

The patent changes both chemical (mild organic acid instead of strong acid) and thermal (75-95°C instead of higher temperatures) parameters. This dual parameter change achieves conversion speeds sufficient for industrial production while minimizing sugar degradation and maintaining high sugar recovery

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses mild organic acids (oxalic acid, citric acid, or lactic acid) as intermediary substances to catalyze the inversion reaction. These intermediary acids provide the necessary catalytic activity for sucrose inversion without the harsh effects of strong mineral acids, thereby reducing sugar degradation while maintaining conversion speed

Inventive Principle:
Principle #24Intermediary (Mediator)
