  • This invention relates to a hand-held and portable, meat grading device, useful for determining the meat properties and tissue composition characteristics of the meat product in question .
  • ultrasound has been applied as a measuring principle for measuring meat and fat attributes on live an imal or on carcasses.
  • A- or B-scanning principles have been taken to farm- and slaughterhouses, where one or several tranducer's are employed, to measure meat and fat transitions, and to establish the thickness of meat and fat tissue attributes, see e.g. US 5872314.
  • the orientation of the product at time of measurement is critical, the direction of the probe towards the meat, and the contact between the meat and probe, is important for obtaining a good measurement.

  • a tactile sensor may also be applied to secure that optimal pressure between the ultrasound (US) probe and the product is established, unless an image analysis of the signal can tell the operator to increase pressure; and
  • the device may also include automated image analysis to recognise landmarks in the meat product for initiation of a measurement of the product.
  • the system above may be combined with a 3D laser information on the physical volumetric measures of the product geometry, which again may be coordinated even the product was moving on a belt, if the laser was not a scanning laser.
