A mechanism (10) is disclosed including a slide plate (32) having die openings (38) adapted to hold dies (42a, 42b) and slideably mounted between the axial downstream face of a barrel extension (20) and an annular pressure seal (56) and the axially upstream face of an annular pressure plate (48). The annular pressure seal (56) is axially adjustably mounted to a first mechanism frame element (18) and the annular pressure plate (48) is mounted to a second mechanism frame element (46). The framework (68) of a cutter assembly (66) is mounted by a hinge (70) to the second mechanism frame element (46) and is carried thereby. The central openings (52, 54) of the annular pressure plate (48) and the second mechanism frame element (46) are frustoconical in shape having circular cross sections to allow exit of food extrudates from the dies (42a, 42b) without hang-up and providing maximum clearance and visibility of the rotary cutter (74) of the cutter assembly (66). The slide plate (32) is slid by a hydraulic cylinder (44) in a linear path to move one of the dies (42a, 42b) from axial alignment with the pressure seal (56) and pressure plate (48) to the other of the dies (42a, 42b) being in axial alignment with the pressure seal (56) and pressure plate (48) without idling the cooker/extruder (12).

Mechanism for removably securing a die to a food cooker/extruder comprising, in combination: a slide plate having an upstream surface, a downstream surface and at least first and second die openings for receiving dies extending from the upstream surface to the downstream surface; a mechanism frame including a first mechanism frame element and a second mechanism frame element; means for securing the first mechanism frame element to the food cooker/extruder; an annular pressure seal having a downstream face and an inner diameter of a size less than the first and second die openings at the upstream surface of the slide plate, with the annular pressure seal held by the first mechanism frame element with the downstream face slideably abutting with the upstream surface of the slide plate and providing a seal generally preventing leakage of food from the die aligned with the inner diameter of the annular pressure seal; an annular pressure plate having an upstream face and a central opening of a size at the upstream face generally equal to the first and second die openings at the downstream surface of the slide plate and increasing with axial spacing from the downstream face of the annular pressure plate, with the annular pressure plate held by the second mechanism frame element with the upstream face slideably abutting with the downstream surface of the slide plate; and means for sliding the slide plate between a first position wherein the first die opening is aligned with the annular pressure seal and annular pressure plate and a second position wherein the second die opening is aligned with the annular pressure seal and annular pressure plate, with the increasing size of the central opening allowing exit of food extrudate from the die without hang-up.
