Acoustic AI for foreign body detection in food manufacturing
Reclamation Factory's Acoustic AI platform offers a novel solution for detecting foreign bodies in food manufacturing using impact audio to classify material properties. Unlike conventional methods, this system identifies contaminants based on mechanical properties, allowing it to detect low-density and low-contrast objects. The technology is currently at TRL 4, with plans for a feasibility study to advance its application in the food sector.
Overview
Reclamation Factory presents a cutting-edge solution for foreign body detection in food manufacturing through its Acoustic AI platform. This technology utilizes impact audio to extract acoustic features that are then analyzed with machine learning algorithms to classify the material properties such as density, stiffness, and composition. This approach allows the system to identify contaminants that traditional methods like metal detectors or X-rays might miss, particularly low-density or low-contrast foreign bodies.
Technical specifications
- Physics-informed acoustic features: Captures and analyzes impact audio to determine mechanical properties relevant for identifying contaminants.
- Machine learning classification: Employs advanced ML algorithms to distinguish between food products and potential contaminants based on their material characteristics.
- Non-intrusive and adaptable: The hardware is designed for easy integration into existing conveyor systems without the need for radiation or RF interference, making it cost-effective and safe for food environments.
- Validated applications: Proven effectiveness in non-food sectors such as municipal plastic waste and bio-based foams.
Technology readiness level
Currently, the Acoustic AI platform is at TRL 4. The proposal outlines a clear path to reach TRL 5-7 through a structured feasibility study and pilot project in the food sector. This involves lab-based validation, feature sensitivity studies, and in-line prototype development to ensure compliance with industry standards and achieve necessary detection sensitivity and throughput requirements.
About Reclamation Factory
Reclamation Factory develops advanced automation and sensing technologies to improve plastic recovery and sorting in recycling and waste management facilities. Their core product, the Plastic Harvester system, utilizes machine vision, optical sensing, and spectral analysis to identify, classify, and sort materials that are often difficult to process with standard visual methods, such as part-form plastics found in e-waste, flat panel displays, and monitor enclosures. The company also offers an acoustic AI system designed to sort materials based on sound, as well as feasibility experimentation services to help operators design and validate processes before deploying new equipment. Their technology provides data-rich tracing and compliance reporting capabilities to ensure material purity and value. By enabling e-waste recyclers to efficiently extract valuable polymers like ABS, PS, and PC from complex waste streams, Reclamation Factory helps facilities maximize the value of recovered materials, minimize contamination, and protect downstream processing equipment. Their solutions integrate directly into existing operations to automate the identification and classification of plastic components at production speeds, supporting circular economy initiatives through improved material recovery rates and accurate sorting of additives and resin types.
