The GRT 620 is equipped with two rows of knifes, forming a tight pattern, whose purpose is to slice the surface of the meat thus increase the product surface area, this process ultimately leads to increased release of myosin during vacuum tumbling and therefore not only an increasing moisture retention during the cooking process also increasing the final tenderness of the meat.

The GRT’s rows of knifes can be adjusted between three different positions, including an adjustable counter pressure of up to 1000N at 6 bars. The knifes are positioned so that they can overlap without coming into contact with each other even when cutting deep into meat. The width between the knifes is 12.5 mm (resulting in a 6.25 mm cuts pattern) or 9mm (resulting in a 4,5 mm cuts pattern). The capacity of the GRT 620 matches the throughput of all our injector models, from GSI 350 up to GSI 820.
