Meat Mincing Machine Weight Accuracy via Separated Material Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Meat mincing machines struggle to accurately separate hard and solid constituents, leading to weight inaccuracies in minced meat portions, as existing separating devices are inefficient in removing items like tendons, sinews, and metal parts, and fail to maintain consistent weight in processed products.
Innovation Solution
A meat mincing machine equipped with a device for determining the amount of separated hard constituents, which includes a conveying mechanism and control system to adjust the volume flow, ensuring accurate weight compensation by adding corresponding amounts of foodstuff, using sensors to monitor the composition and adjust the separation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a separating device is used to remove hard constituents, then the purity of minced meat is improved, but weight accuracy of portions deteriorates due to separated material
Solution Approach 1:
The patent implements a feedback mechanism where a sensor detects the amount of separated hard constituents and feeds this information to a control device. The control device then adjusts the volume flow of minced meat to compensate for the removed material, ensuring weight accuracy is maintained despite the separation process improving purity.
Solution Approach 2:
The system dynamically changes the volume flow parameter of minced meat based on the detected amount of separated constituents. By adjusting this parameter in real-time, the system compensates for material removal and maintains consistent portion weights while achieving high purity through separation.
2Reliability
If hard constituents are separated from minced meat, then the quality of minced meat is improved, but the weight of portions becomes inaccurate
Solution Approach 1:
The sensor continuously monitors the separation process and provides feedback to the control device about the amount of hard constituents removed. This feedback loop enables real-time adjustment of the volume flow to compensate for separated material, maintaining both quality improvement through separation and weight accuracy in portions.
Solution Approach 2:
The patent replaces traditional mechanical weighing and adjustment systems with a sensor-based detection and electronic control system. This substitution enables more precise and dynamic compensation for separated material, maintaining portion weight accuracy while achieving reliable quality improvement through separation.
3Productivity
If a conveying device is used to draw off separated product, then the separation efficiency is improved, but the complexity of the device increases
Solution Approach 1:
The conveying device is integrated into the existing mincing system and serves multiple functions: it transports minced meat through the separation zone, collects separated hard constituents, and provides the basis for measuring separated material volume. This multi-functionality improves separation efficiency while minimizing the increase in device complexity by utilizing existing structural elements for multiple purposes.
