Detect abnormal sounds during meat sliding to prevent the mixing of hard bones!
This document introduces examples of measurement systems that determine the presence of hard bone contamination in meat products. In many meat processing centers, all meat is inspected using soft X-rays to check for the presence of bone fragments. However, if bone fragments are embedded within fat, they cannot be distinguished. Our analysis shows that when bone fragments are sliced with a meat slicer, a specific frequency range (sound/vibration) changes. By attaching a vibration sensor to the bearing section of the rotating blade, we can capture this slight change in vibration and determine the presence of bone fragments through FFT 1/3 octave analysis.

Detailed information

As automation progresses in production equipment abnormalities and product inspections, "visual" judgments using X-rays and images are generally well-known. However, the "sensory inspection" methods, such as auditory and tactile assessments—traditionally performed by skilled technicians—based on "sound and vibration" seem to be less recognized. At Elmek, which has over 40 years of experience in the automation and development of judgment systems based on "sound and vibration" sensory inspections, we offer measurement and judgment systems capable of addressing various cases, utilizing our analytical know-how built on extensive experience and years of technology.

"DAOS" is software suitable for noise and vibration-related analysis that can provide detailed reports on trends, histograms, and other analysis results, as well as beautifully visualize analysis data. It allows for the visualization of analysis results from multiple files, making it easy to distinguish between good and defective products at a glance. It performs octave analysis of time-series data and analyzes various waveform indicators quickly and easily. Once the settings are configured, efficient analysis can be conducted simply by selecting files.
