摘要:
A method of extruding products comprises varying the rate of flow of at least one material (12) through an extrusion aperture in a die (10). The method may be used to produce an extrudate body (16) whose cross-sectional area varies along its length or to produce an extrudate body comprising two or more different materials in which the proportions of the materials varies along its length. Apparatus (11) for carrying out the method comprises an extrusion die (10) defining an extrusion aperture and a material delivery system for delivering the material(s) to the die in a suitable condition for extrusion. A control system is operative to vary the rate of flow of the material. The control system may comprise a flow control mechanism (240) in a supply path for the first material upstream from the die (10). The flow control mechanism (240) may be operative to vary the volume of the supply path and may comprise a fluid actuated resiliently deformable flexible element. The method and apparatus are particularly suited for manufacturing food products, especially confectionery products such as chocolate bars.

An apparatus 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 having screw augers for advancing a plastic food mass, a head or manifold for dividing the plastic food mass into a plurality of substreams each in turn in fluid communication with a plurality of sub-divided dough passageways, and a die head having a plurality of die ports. Each subpassage is separately supplied an additive and has disposed therein a multiplicity of in-line static mixer elements to admix the additive into the substreams of the plastic food mass before passage through the die ports. In a preferred form, first and second substreams are intermixed in a non-homogenous manner before reaching the exit ports. The extrudates are severed into individual pieces by a rotary cutter.

An improved system and method to produce a bread product is disclosed. Bread products that produced with the system and method are also disclosed. The bread products are intended for commercial manufacture with high volume and efficiency. The system and method produce bread products from multiple dough components; one dough component provides an interior core; another dough product provides an exterior layer. When the bread product is baked, a multi-component bread product is formed where the crumb is provided by the dough component of the interior core and the crust is provided by exterior surface of the dough component of the exterior layer. Any of a wide variety of types and forms and shapes and sizes and etc. of bread products may be produced. The system and method may be performed using any of a wide variety of production techniques. Each dough component may be formulated (and may include an improver) to facilitate the operation of the system and method and to provide a tasteful and appealing bread product.

A gas assisted co-extrusion apparatus includes a co-extrusion die in communication with an extruder. A nozzle that is defined by a bore in the co-extrusion die extends about a nozzle axis to a nozzle exit of the co-extrusion die. An injector extends through the bore of the co-extrusion die along the nozzle axis. The injector and nozzle together form a dough into a rope that is tubular with a wall portion and an inner cavity surrounded by the wall portion as the dough is extruded out of the nozzle exit and about the injector. A compressed gas source provides a compressed gas out of an injector outlet and into the inner cavity of the rope to radially stretch the wall portion of the rope as the rope is dispersed from the injector. The co-extrusion die is spaced from the extruder to define a void therebetween. A delivery system delivers an entrainable material to the compressed gas in a pipe. The pipe is connected to an injector inlet of the injector in the void. This allows the pipe to operate within the ambient temperature of the environment and for the entrainable material to be entrained into the compressed gas prior to being introduced into the injector.

An extrusion die head for the extrusion of hollow or center-filled shapes as well as apparatus comprising the extrusion die head and methods employing the die head. The extrusion die head (10) is for the preparation of a plurality of center-filled products (34) of varying composition wherein each product comprises a first (filling) material and a second (outer) material. The die head comprises at least one tube (22) such that a first material may be extruded through the tube or tubes and a second material may be extruded around the tube or tubes. The location and the number of the tubes may be customized to vary the location and amount of the first material relative to the second material and thereby vary the composition of the center-filled product. The extrusion die head apparatus comprises a sleeve (40) enclosing the die head. In one embodiment a first material is conveyed from one or more first apertures (18) via one or more tubes (22) to one or more second apertures (20) where it is extruded. Simultaneously, a second material is supplied directly to the remaining second apertures (20) where it is extruded.

Apparatus and methods for fabricating food items include extruding a first hot plastic food mass through multiple passages and co-extruding a second hot plastic food mass through a feed stem received in each of the multiple passages and through nozzles. Each nozzle includes a first portion in communication with the feed stem but not the passage and a second portion in communication with the passage but not the feed stem. The nozzles are rotatable in gearing relation with the drive gear of a servomotor. The co-extruded ropes are conveyed at a linear speed rate less than or equal to the discharge speed from the nozzles, cooled, and cut into individual pieces in the form of peelably separable strands.

摘要:
A die and cutter assembly for an extruder includes an elongated extrusion member having a first, open end and a second, closed end. The first, open end is attachable in fluid communication with a first manifold of the extruder, and the second, closed end is formed by a removable extrusion end cap. An extension is formed on the elongated extrusion member. A filling passageway is formed in a wall of the elongated extrusion member, which is attachable to a second manifold of the extruder. A first filling passageway extension is in communication with and removably mounted to the filling passageway. The first filling passageway extension generally transverse to the filling passageway and extends into the extension of the elongated extrusion member. An extrusion die is formed on the extension of the elongated extrusion member. A cutter member has an opened drivable end, an elongated cutter wall, and an opened cutter end with a cutting surface for cutting extrudate to a desired length as the extrudate exits the die. The cutter member is disposed at least partially over and reciprocally slideable on the extrusion wall and operably connectable at the drivable end to a drive device of the extruder for reciprocatably sliding the cutting surface of the cutter member over and away from the extrusion die.
