  • Publication number: 20020110634
    Abstract: A method and system for processing at least one rope of aerated confectionery foam. The method includes extruding at least one rope of aerated confectionery foam from an extruder. The rope is conveyed from the extruder to a rotary cutter. An anti-sticking agent, such as powdered starch, is applied to the rope as the rope is conveyed from the extruder to the rotary cutter. Finally, the rope is cut into pieces with the rotary cutter. In one preferred embodiment, the rotary cutter is operated to perform at least 5,000 cuts per minute.

  • Patent number: 6387421
    Abstract: An extrudable food product is provided by a food cooker extruder (12) and is mixed with an additive to form a patterned food product, using a pattern forming die (20, 220). The cross-sectional area of the patterned food product is reduced from an inlet end (34) to an outlet end (36) by a factor of at least 50:1 at an average convergence angle of ≦45° while maintaining the cross-sectional pattern to form a reduced cross-sectional patterned dough, and then is extruded through a die port (13) having an opening equal to the reduced cross-sectional area to form a complexly patterned extrudate. The food product comprising, multiple extrudates are simultaneously formed with the flow rates for each extrudate being adjustable by an adjuster plug (16) including a smooth cylindrical portion (86) extendable into a passageway (14) having a circular cross section of a larger diameter than the cylindrical portion (86).

  • Patent number: 6189439
    Abstract: A mechanism (10) includes a slide plate (32) having die openings (38) adapted to hold dies (42a, 42b) and slideable relative to a cooker/extruder (12). Rotary cutters (74, 174) are rotatably mounted relative to and moveable with the dies (42a, 42b). In one preferred form, a motor (76) can be connected and disconnected to the rotary cutter (74) aligned with the cooker/extruder (12) by moving a male coupling (96) within or out of a female coupling (108). In another preferred form, the rotary cutter (174) is mounted to and carried exclusively by a center shaft (180) fixed to the die (42a, 42b) and includes provisions (187, 191) located within a housing (183) for rotating the housing (183) on the center shaft (180). Thus, it is not necessary to shut down the cooker/extruder (12) to service or change the dies (42a, 42b) and/or the rotary cutters (74, 174).

Rotary cutters (74) are rotatably mounted relative to and moveable with the dies (42a, 42b). In one preferred form, a motor (76) can be connected and disconnected to the rotary cutter (74) aligned with the cooker/extruder (12) by a male coupling (96) including an elastomeric band (106) tensioned in a groove (102) formed in an outer peripheral surface (100) and received within the inside surface (116) of a cylindrical body (114) of a female coupling (108). Thus, it is not necessary to shut down the cooker/extruder (12) to service or change the dies (42a, 42b) and/or the rotary cutters (74). An annular wear plate (134) is sandwiched between the slide plate (32) and a frame element (18) having a central aperture (126) into which the barrel (14) of the cooker/extruder (12) is slideably received.

  • Patent number: 5958485
    Abstract: A food item is disclosed produced in the preferred form by an apparatus (10) including first and second forming rollers (18, 21) which rotatably abut with an anvil roller (20). The forming rollers (18, 21) each include a periphery forming a continuous forming surface including a plurality of axially and circumferentially spaced grooves (24) each formed as a continuous depression arranged in a serpentine and non-intersecting manner. Food (14) is simultaneously fed by a saddle (36, 36') between a continuous strip of support material (16) and a continuous ribbon of film material (66) as they pass between a first abutment nip of the first forming roller (18) and the anvil roller (20). In a preferred form, the saddle (36') is in the form of a block having first and second lower surfaces (118, 120) corresponding to the shape and located adjacent the first forming roller (18) and the anvil roller (20) in their mating side (32).

  • Patent number: 5919509
    Abstract: An apparatus (10) for forming a single extrudable food stream such as a cooked cereal dough into a plurality of differently colored and/or flavored dough streams is disclosed including an extruder (12) having screw augers (15) in a main passageway (14) for advancing a plastic food mass, a head or manifold (18) for dividing the plastic food mass into a plurality of substreams such as a branching passageway section in fluid communication with a plurality of sub-divided dough passageways, and a die head (30) having a plurality of die ports (40) for each subpassageway. Each subpassage is separately supplied an additive and has disposed therein a multiplicity of in-line static mixer elements (59) to admix the additive into the substreams of the plastic food mass before passage through the die ports (40). In a preferred form, a portion of the food mass is bled from a first substream and fed to the exit ports (40) of a second substeam to create an extrudate including zones of distinct food mass.
