Headwall, Bratney to Collaborate on Food Imaging

Facebook X LinkedIn Email
Hyperspectral imagers from Headwall Photonics Inc. will be integrated into machine vision systems for food handling from Bratney Companies of Des Moines, Iowa.

Bratney's systems help sort and grade high-value nuts and whole food products, reducing the need for human hand-sorting. Headwall's Hyperspec sensors cover spectral ranges of interest, providing crucial image data from every pixel within the field of view for the real-time operation of production lines. Spectral and shape discrimination algorithms are applied to inspect and grade processed food items, resulting in a much higher level of discrimination and producing a higher quality product.

"This technology allows us to detect defects and infractions both visible and invisible to the human eye," said Peter Bratney, CEO of the Bratney Companies. "Therefore, separations which are far beyond the capabilities of traditional human sorters are now possible, which is a tremendous benefit to our customers."

The Hyperspec system controls the operation of the sensor hardware and monitors the flow of product along a conveyor belt, driving the action of the robotic ejection devices and allowing the picking and sorting equipment to manage spectral data.

"This is a targeted spectral imaging solution addressing a critical quality assessment need within the food processing industry," said David Bannon, CEO of Headwall. "When it comes to high-value nuts, seeds and specialty crops and grains, the ability to determine overall quality based on chemical and shape characteristics is a key attribute of Bratney's pick and sort technology."

Headwall Photonics designs and manufactures imaging spectrometers and spectral instrumentation for industrial, commercial and government markets. The Bratney Companies provide cleaning, packaging, separation, material handling and storage equipment for customers in the seed, grain, feed, nut and specialty industries.

Glossary
hyperspectral imaging
Hyperspectral imaging is an advanced imaging technique that captures and processes information from across the electromagnetic spectrum. Unlike traditional imaging systems that record only a few spectral bands (such as red, green, and blue in visible light), hyperspectral imaging collects data in numerous contiguous bands, covering a wide range of wavelengths. This extended spectral coverage enables detailed analysis and characterization of materials based on their spectral signatures. Key...
machine vision
Machine vision, also known as computer vision or computer sight, refers to the technology that enables machines, typically computers, to interpret and understand visual information from the world, much like the human visual system. It involves the development and application of algorithms and systems that allow machines to acquire, process, analyze, and make decisions based on visual data. Key aspects of machine vision include: Image acquisition: Machine vision systems use various...
