Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial batch processes for producing beverages face challenges in monitoring and maintaining product quality due to manual ingredient addition and visual inspection, leading to potential errors, inconsistent batch quality, and the need for costly post-batch analysis.
Innovation Solution
Implementing an in-line density device that continuously measures density and drive gain during the batch process, allowing for real-time monitoring and correction of deviations from a standard recipe, ensuring ingredients are fully mixed and the batch meets quality standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual ingredient addition and visual inspection are used, then the process is simple to operate, but the manufacturing precision and reliability of batch quality are poor
Solution Approach 1:
The patent replaces manual visual inspection with an optical density measurement system. The in-line density device uses optical principles to automatically measure and monitor batch density, substituting human visual assessment with precise instrumental measurement. This resolves the contradiction by providing objective, quantitative data for quality control without requiring complex mechanical intervention in the mixing process.
Solution Approach 2:
The system continuously monitors batch density in real-time and provides feedback to operators or control systems. When density deviations from the standard recipe are detected, the system alerts operators to make corrections. This closed-loop feedback mechanism ensures consistent batch quality while keeping the overall system relatively simple, as it builds upon existing batch process infrastructure.
2Reliability
If real-time density monitoring is implemented, then the manufacturing precision and quality control are improved, but the device complexity and cost increase
Solution Approach 1:
The in-line density device serves multiple functions: it measures batch density, monitors ingredient mixing completion, detects deviations from standard recipes, and provides real-time quality assurance data. By consolidating these quality control functions into a single instrument, the system achieves high reliability without proportionally increasing complexity, as the device leverages its multi-functionality to maximize value from a single addition to the batch process.
3Measurement precision
If post-batch analysis is used, then the measurement can be thorough, but the loss of time and productivity are increased
Solution Approach 1:
The system performs density measurements continuously during the batch process rather than waiting for completion. By monitoring density in real-time as ingredients are added and mixed, the system identifies quality issues during production, allowing for immediate correction before the batch is finalized. This preliminary detection approach maintains measurement accuracy while preventing the time loss associated with post-batch analysis and potential rework.
Solution Approach 2:
The density measurement process operates continuously throughout the batch production cycle, providing uninterrupted quality monitoring. The in-line device remains active during ingredient addition, mixing, and formulation stages, ensuring that quality assessment is an ongoing process rather than a discrete post-processing step. This continuous monitoring maintains measurement precision while maximizing productivity by eliminating idle analysis time.
