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
Engineering 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
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
2Productivity
If high temperature treatment is applied for sucrose inversion, then inversion rate increases, but caramelization occurs causing darker color
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
3Speed
If strong acid and high temperature are used for inversion, then conversion speed increases, but sugar degradation increases
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
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
