Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial processing equipment, particularly ethanol fermentation tanks, face challenges in removing resistant starch residues due to complexation with metal ions, which are not effectively addressed by conventional heated sodium hydroxide solutions.
Innovation Solution
An aqueous cleaning solution composition combining sodium hydroxide and potassium sodium tartrate, maintained at elevated temperatures, effectively removes starch residues and metal ions by chelating action, allowing sodium hydroxide to break down the residues at lower concentrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heated concentrated sodium hydroxide solution is used to clean starch residues, then cleaning capability is improved, but sodium hydroxide concentration must be high which increases cost and equipment corrosion
Solution Approach 1:
The patent introduces potassium sodium tartrate as a chelating agent that acts as an intermediary substance. It binds to metal ions (calcium, magnesium, iron) that catalyze starch degradation and form resistant complexes, thereby enhancing the cleaning effectiveness of sodium hydroxide and allowing lower concentrations to be used effectively.
Solution Approach 2:
The cleaning composition is formulated as a composite system combining sodium hydroxide (for base cleaning action) with potassium sodium tartrate (for chelating metal ions). This composite approach creates synergistic effects where the combination of substances achieves superior cleaning performance compared to sodium hydroxide alone, enabling reduced sodium hydroxide concentration while maintaining or improving cleaning capability.
2Reliability
If high concentration sodium hydroxide is used to remove starch residues, then cleaning effectiveness is improved, but equipment corrosion and safety hazards increase
Solution Approach 1:
Potassium sodium tartrate serves as a protective intermediary that chelates metal ions responsible for catalyzing starch degradation and equipment corrosion. By binding these metal ions, it reduces the corrosive action on equipment surfaces while maintaining cleaning effectiveness at lower sodium hydroxide concentrations.
Solution Approach 2:
The invention changes the chemical parameters of the cleaning system by adding a chelating agent, which modifies the mechanism of action. This allows the system to achieve the same cleaning effectiveness at lower sodium hydroxide concentrations (reducing from typical high concentrations to lower effective concentrations), thereby reducing equipment corrosion and safety hazards.
3Device complexity
If conventional cleaning processes are used, then process simplicity is maintained, but cleaning time increases due to resistant starch residues
Solution Approach 1:
The addition of potassium sodium tartrate as a chelating intermediary accelerates the cleaning process by preventing metal ion-catalyzed starch degradation. This chemical enhancement allows the cleaning process to proceed faster and more effectively without complicating the overall process flow or equipment requirements.
Solution Approach 2:
By modifying the chemical composition parameters (adding chelating agent), the cleaning process achieves faster residue removal. This parameter change enhances cleaning kinetics and effectiveness, reducing the time required for effective cleaning while maintaining process simplicity.
