Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sensors used in food processing systems, particularly those measuring properties of process water, are prone to fouling by adhering materials like lipids, leading to reduced effectiveness and potential health risks due to inaccurate measurements.
Innovation Solution
A water control system with a temperature adjustment element positioned upstream of the sensor to adjust the temperature of process water, mitigating fouling effects by heating or cooling the water to prevent lipid accumulation on the sensor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are placed in direct contact with process water to measure properties, then measurement capability is improved, but sensor fouling by lipids increases
Solution Approach 1:
A temperature adjustment element is introduced as an intermediary component between the process water and the sensor. This element modifies the temperature of the water to prevent lipid accumulation on the sensor surface, thereby maintaining measurement capability while reducing fouling effects.
Solution Approach 2:
The temperature of the process water is changed as a control parameter to mitigate fouling. By adjusting the temperature, the physical state and behavior of lipids are altered, preventing them from adhering to the sensor and maintaining measurement precision.
2Reliability
If temperature adjustment element is added to mitigate fouling, then sensor performance is improved, but system complexity increases
Solution Approach 1:
The temperature adjustment element serves as a simple intermediary device that directly addresses the fouling problem without requiring complex control systems or multiple components, thus improving sensor performance with minimal increase in system complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively reduces sensor fouling by softening or liquefying lipids, ensuring accurate measurement of process water properties and maintaining hygiene control in food processing systems.
Implementation Method 1
The temperature adjustment element is generally configured to: receive, at the inlet of the temperature adjustment element, a portion of process water from a process water supply in a stage of the food processing system, the process water in the process water supply and the received portion of the process water having a first temperature; and cause the portion of the process water at the outlet of the temperature adjustment element to have a second temperature, different from the first temperature.
Implementation Method 2
The temperature adjustment element is generally configured to: receive, at the inlet of the temperature adjustment element, a portion of process water from a process water supply in a stage of the food processing system, the process water in the process water supply and the received portion of the process water having a first temperature; and cause the portion of the process water at the outlet of the temperature adjustment element to have a second temperature, different from the first temperature.
