TOMRA’s QV-P in-line analyser can reliably detect the muscle myopathy in single chicken fillets or butterflies. This allows to remove wooden breast fillets from the processing line, ensuring consistent end-user quality.

The TOMRA QV-P is an in-line detector for the identification of chicken wooden breast - a condition that affects broiler chickens, making the meat hard and chewy.

Utilizing established, patented technology, TOMRA has expanded the range of applications for its offering in the meat and poultry sector. The TOMRA QV-P is the world’s first in-line detection machine for the identification of wooden breast in chicken fillets and butterflies, and allows processors to accurately grade chicken fillets against specific criteria.

The unique solution, which uses multi spectral lights to allow high speed analysis of the chicken fillets, was showcased at the IPPE (International Production & Processing Expo) in Atlanta, Georgia, earlier this year.

The dedicated software allows the TOMRA QV-P to accurately grade chicken fillets into multiple grades, determined by the customer, on the severity of wooden breast in the fillet or butterfly.

Previously, processors had to manually review each chicken fillet before processing, in what was called a ‘thumb check’. With TOMRA’s new in-line analyzer, these time-consuming, labor-intensive, manual checks are no longer needed.

  • Consistent grading
  • Guaranteed customer quality
  • High speed analysis


Key features

Sensor Technology

TOMRA’s unique interactance spectroscopy allows to measure into the fillet and determine the internal composition of the meat. Without harmful radiation, it measures each filet or butterfly and provides feedback to the processing line.
The TOMRA QV-P optical head can easily be installed above existing chicken breast processing lines to allow sorting.
