Apparatus and methods for producing multiple extruded products having different characteristics from the extruded stream of a single main extruder are provided. A satellite extruder assembly is removably attached to a main extruder allowing for the production of a plurality of different extrusion products from a single stream from one main extruder that is divided into multiple streams channeled to a plurality of satellite extruders. Each of the extruders may be operated at different temperature, pressure, moisture and shear conditions. Additional components may be selectively added to one or more of the material streams.

Apparatus and methods for food production including a food preconditioner (228) operable to heat and partially pre-cook food ingredients, and a twin screw extruder (20) operable to further cook the preconditioned ingredients to create final food products. The extruder (20) includes a pair of hollow core extrusion screws (50, 52, 124, 126, 190) having elongated hollow core shafts (54, 128, 130, 192) equipped with helical fighting (56, 132, 134, 194) along the lengths thereof. The fighting (132, 134, 194) is also of hollow construction which communicates with the hollow core shafts (54, 128, 130, 192). The fighting (56, 132, 134, 194) also includes forward, reverse pitch sections (64, 162, 216). The extrusion screws (50, 52, 124, 126, 190) are designed to impart high levels of thermal energy into materials being processed in the extruders (20), without adding additional moisture.

A die for edible products for animals. The die may include at least one through drawing cavity having a prevalent development along a longitudinal direction. The through cavity may include at least one first group of grooves and a second group of grooves having a development substantially parallel to the longitudinal direction. In a transversal section with respect to the longitudinal direction, each groove of the first group has a greater depth with respect to the depth of each groove of the second group and each groove of the first group alternates with a groove of the second group.

A process to remove the glucosinolates of oilseed meals, such as Brassica carinata oilseed meals, is provided. In one embodiment, exogenous myrosinase is used to convert the glucosinolates to volatile isothiocyanate compounds, which can then be removed under conditions of mild heat and negative pressure. In another embodiment, heat and pressure are used to remove glucosinolates from Brassica carinata oilseed. The processed meals may contain less than 80% of their starting levels of glucosinolates and may be suitable for use in various applications, including as animal feeds.

Apparatus and method for treating a product with steam. The apparatus includes a treatment tunnel having an entrance opening and an exit opening for introducing and discharging the product, respectively. The apparatus includes a transport unit for transporting the product from the entrance opening to the exit opening and a steam feed unit for feeding steam into the treatment tunnel. The apparatus includes one or more nozzles in communication with the steam feed unit arranged for directing a jet of steam at the product.

An apparatus for making a canned food product in a can, the food product including a first composition and a second composition, and the apparatus includes a filling head including a first channel and a second channel for respectively directing the first composition and the second composition into the can. A first supply assembly includes a first supply container containing the first composition, and the first supply container is connected to the first channel; and a second supply assembly. The second supply assembly includes a second supply container containing the second composition; a dosing piston connected to the second supply container through a third channel; a hose connecting the dosing piston to the second channel; and one or more rotary valves between the dosing piston and the filling head.

A cooling tool (1) for a food or an animal feed extruder (E), the cooling tool has: an inlet end (3) at which extrudate (4) can be led into the cooling tool (1); an outlet end (5) where the cooled extrudate can be discharged; an extrudate flow channel (6) extending from the inlet end to the outlet end; and at least one coolant flow channel (7a, 7b, 7b′) connected to the extrudate flow channel in a heat-transmitting manner. In a cross section (X-X) along the primary flow direction (8), the extrudate flow channel is substantially formed as a ring section; and the outer wall (9) of the extrudate flow channel (6) is formed at least from first and second segments (10, 11). The first and second segments are connected to each other by mechanical connection elements (12). The cooling tool is suitable for wet texturing of food and animal feed.

High thermal transfer, hollow core extrusion screws (50, 52, 124, 126, 190) include elongated hollow core shafts (54, 128, 130, 192) equipped with helical fighting (56, 132, 134, 194) along the lengths thereof. The fighting (132, 134, 194) may also be of hollow construction which communicates with the hollow core shafts (54, 128, 130, 192). Structure (88, 90) is provided for delivery of heat exchange media (e.g., steam) into the hollow core shafts (54, 128, 130, 192) and the hollow fighting (132, 134, 194). The fighting (56, 132, 134, 194) also includes a forward, reverse pitch section (64, 162, 216). The extrusion screws (50, 52, 124, 126, 190) are designed to be used as complemental pairs as a part of twin screw processing devices (20), and are designed to impart high levels of thermal energy into materials being processed in the devices (20), without adding additional moisture.

A kit for molding and storing malleable foodstuff includes (a) a molding tube; (b) a plunger slidable within the molding tube for tamping foodstuff received therein to form a shaped food article corresponding in shape to an interior of the molding tube; and (c) at least one storage tube sized and shaped for storing the shaped food article therein with reduced surface area contact relative to the molding tube.

Described herein are methods and systems for preparing a plurality of compositions on a commercial scale, without interruption.
