  • Patent number: 5639485
    Abstract: Disclosed are apparatus (10) for making a complexly patterned extrudate. The apparatus (10) includes a food cooker extruder (12) for providing at least one extrudable food product, at least one food color supply (18), a pattern forming die (20) for mixing the food color and extrudate food product to form a complexly patterned food product, a reducing passageway for reducing the cross sectional area of the patterned dough from an inlet end (34) to outlet end (36) of at least 50:1 at an average convergence angle of .ltoreq.45.degree. and an extruder exit port at the discharge end of the reducing passageway.

  • Patent number: 5518749
    Abstract: An assembly (10) is disclosed including a rotor (38) extending into a rotor bore (24) and into a dough chamber (26) of a die housing (16), with the rotor (38) rotating at relatively high speeds in the order of 4,000 RPM. A bushing (62) is provided in the rotor bore (24) to provide a seal with the rotor (38). The bushing (62) has a small clearance with the rotor (38) sufficient to reduce frictional forces to minimize wear while effectively preventing passage of the extrudable dough under pressure in the order of 2,800 psi (200 kg per square centimeter) through the rotor bore (24) and around the rotor (38). The dough which does pass through the small clearance is allowed to fall away from the rotor (38) outside of the rotor bore (24).

  • Patent number: 5435236
    Abstract: An apparatus for pneumatically conveying a plurality of continuous ropes (20) of cooked cereal dough (20), e.g., from the diehead (24) of a cereal ingredients cooker extruder (22) to a cereal piece forming apparatus. The apparatus (10) includes a plurality of conveyance tubes (12, 14, 16, 18) each comprising a telescoping, flared inlet member (30) for adjustably connecting to the diehead (24) to facilitate start-up; a means for supplying conditioned air to cool and/or dry the rope during conveyance (36); a venturi eductor (40) to provide pneumatic conveyance; and an elongated conveyance tube (48). In preferred embodiments, the apparatus further includes a motive air supply system for multiple adjustable venturis but employing a single air compressor.

  • Patent number: 5336076
    Abstract: An apparatus (79) for setting the nip gap between first and second rollers (30, 32) includes nip control blocks (83) movably mounted adjacent the front edges (150) of the end plates (151a, 151b) between which one of the rollers (32) is journaled. In the preferred form, each of the control blocks (83) are threadably received on a shaft (138) and include a slide surface (142) which slides on a shoe (134) mounted on the end plates (151a, 151b) and include an opposite, abutment surface (144) at a minor acute angle to the slide surface (142) and the movement direction of the control blocks (83). Contact surfaces (164) are articulately mounted to the end plates (51a, 51b) between which the other of the rollers (30) is journaled. In the preferred form, the contact surfaces (164) are formed on a thrust knuckle (160) having a semi-spherical surface (162) slideably received in a semi-spherical depression (156) of a thrust socket (154) secured in a recess (146) in the front edges (150) of the end plates (51a, 51b).

  • Patent number: 4836196
    Abstract: An apparatus for connecting a structure with a vertebral body of a spinal column and for transmitting a load between the structure and the vertebral body. The apparatus includes a fastener with a threaded portion for threaded engagement with a surface defining an opening in the vertebral body to connect the vertebral body with the structure. A spacer is adapted to be located between the fastener and the structure for transmitting load therebetween. The spacer is made of a material which plastically deforms as a function of time and load applied thereto to decrease the load transmitted between the vertebral body and the structure.
