An extruder for extruding pasta in the form of a continuous thin strip in a pasta-making machine, more particularly for domestic use. The extruder comprises a first tubular body and a coaxial inner jacket defining a circular opening of predetermined diameter "D". A second tubular body having a flange comprises a coaxial cylindrical body held in position by a number of rigid radial elements defining passages and is engaged coaxially in body. The outer diameter "d" of body is less than the diameter "D" and defines a slot for extruding pasta in the form of a continuous tube which is automatically cut along a generatrix by a tooth secured to the outer surface of body. The components of extruder can be axially dismantled in order to remove residues of pasta after the extrusion process. Jacket also has projections which slow down the pasta as it travels in the passage, thus bringing it to the same speed as the pasta encountering the radial elements.
An extrusion nozzle for ground meat which has forwardly mounted perforation rods, aligned and retained within tubular housings, with each lateral rod having a slight bend so that it is generally parallel with the interior walls of the nozzle. The nozzle attaches to a conventional meat grinder which forces the semi-frozen ground meat into the nozzle and compacts and extrudes the shapeless meat into a densely packed, bricklike shape having multiple perforations without the requirement for external heating. This nozzle affords ease in cooking and enhanced flavor, is easily cleaned, requires minimum disassembly, and is structurally supported to withstand internal pressures.
Compounds of the formula ##STR1## are disclosed. These compounds are useful as hypotensive agents due to their angiotensin converting enzyme inhibition activity and depending upon the definition of X may also be useful as analgesics due to their enkephalinase inhibition activity.
An improved pasta maker (20) is provided having an upper mixing chamber (130), lower extrusion chamber (132), and a communicating passageway (157) therebetween. The mixing chamber (130) is an open top vessel, and the extrusion chamber (132) presents an outlet (148) adapted to receive a pasta forming die (188). The pasta maker (20) also includes an apertured slide valve plate (26), a powered, rotatable mixing element (170) within the mixing chamber (130) for mixing of the ingredients therein, and a powered, axially rotatable auger (174) within the extrusion chamber (132) for conveying the ingredients towards and through the die (188). The valve plate (26) is removably and shiftably mounted within the passageway (157) for selective movement between a first mixing position blocking communication between the chambers (130, 132), a second feeding position wherein the plate aperture (214) is in registry with openings (136, 150) for communicating the chambers (130, 132), and a third cleaning position wherein the plate (26) is detached from the passageway (157). In the second position, the valve plate (26) is restrained from outward movement towards the third position by interengagement of a pair of laterally spaced, upstanding nibs (220) formed on the plate (26) and the inner surface of sidewall (34) of the machine, and restrained from inward movement towards the first position by the mixing element (170), upon the rotation of the same and when mixed pasta making ingredients are in the mixing chamber (130), urging the plate (26) outwardly.
A die assembly for use in a continuous extrusion apparatus is made up of two cooperating members. The first member has tapered apertures therethrough disposed symmetrically about a mandrel portion. The mandrel portion cooperates with a throat portion in the second member to define an extrusion gap. A ceramic insert can be located in the second member to reduce wear during the extrusion of materials such as copper.
