摘要： A jet-knife assembly for meats or like products is provided which assures even, predictable grinding with a minimum of objectionable fines or agglomerated strings, so as to yield final products of consistent dimensions and characteristics. The overall assembly preferably includes a plate presenting only a single set of circularly arrayed apertures therethrough, together with a cooperating, multiple-blade, rotating knife adjacent the plate; the knife blades each have elongated fluid-conveying channels along the operating faces thereof, which are sized relative to the plate apertures so that the cross-sectional area of the channel is always greater than the total plate open area in communication with the channel during blade rotation. Pressurized steam or air is directed to the blade channels during operations, so that as the knife rotates and blade channels come into communication with the plate apertures, product is expelled or "popped" out of the plate apertures. Provision of non-bridging blade channels assures substantially constant pressure conditions at each plate aperture to yield the most consistent final products.
