Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clean out of place (COP) methods in the food and meat processing industries face challenges with short dwell time and low foam stability of no-foaming or low foaming cleaning compositions, leading to inefficient soil removal and increased energy and water consumption.
Innovation Solution
An aqueous foaming cleaning composition comprising C12-alkyl dimethylamine oxide, C14-alkyl dimethylamine oxide, dodecyl (oxyethylen) sulfat, and polyoxyalkylene alkyl ether carboxylic acid or salt, which provides increased foam stability and dwell time, allowing effective soil removal at lower temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no-foaming or low foaming liquid cleaning compositions are used, then the cleaning composition flows well and can be easily applied, but the dwell time on upright surfaces is short and foam stability is low
Solution Approach 1:
The patent changes the physical state parameter of the cleaning composition from liquid to foam form. This foam formulation maintains ease of application while providing extended dwell time on vertical surfaces, directly resolving the contradiction between application ease and dwell time duration.
2Reliability
If high temperatures (up to 80° C.) are used for cleaning, then soil removal effectiveness is improved, but energy consumption increases significantly
Solution Approach 1:
The patent changes the temperature parameter from high (80°C) to low (ambient or cool temperatures). The foam cleaning composition achieves effective soil removal at these lower temperatures through its enhanced dwell time and foam stability, thereby reducing energy consumption while maintaining cleaning effectiveness.
3Productivity
If no-foaming or low foaming compositions are used, then the composition can penetrate soils effectively, but the user cannot easily track treated areas leading to double treatment and increased water consumption
Solution Approach 1:
The patent incorporates color indicators or visual markers in the foam composition that allow users to easily track treated areas. This visual feedback mechanism prevents double treatment of surfaces and reduces water consumption, while the foam's extended dwell time maintains cleaning effectiveness.
4Ease of operation
If liquid cleaning compositions with good flow rate are used, then the composition can be easily distributed over surfaces, but the residence time on the surface is brief
Solution Approach 1:
The patent utilizes the phase transition from liquid to foam form. The foam structure provides both easy distribution (similar to liquid flow) and extended residence time on surfaces, as the foam bubbles adhere to vertical and overhead surfaces much longer than liquid compositions.
