Disclosed are various embodiments of an extruded expandable barrier, and various processes and systems for manufacturing the same. Using various extrusion processes to form an extruded expandable barrier allows for a reduction in tooling costs while also allowing more flexible barrier designs. Such designs can be specifically tailored for a particular cavity or cavities to ensure that the barrier fills the cavity after expansion. In addition, design changes can occur with little to no tooling changes.

A system for high moisture extrusion (HME) food processing using an adjustable height cooling die including an automatic dynamic HME feedback loop is described herein. In various embodiments, the system comprises: a high moisture extrusion (HME) system including adjustable input HME parameters to adjust resulting HME parameters thereby controlling quality of HME products, the high moisture extrusion (HME) system comprising: a feeding system; a barrel, the barrel comprising at least one screw; and the adjustable height cooling die for shaping of a food product comprising output product conditions.

An extruder screw conveying raw materials while kneading them includes a screw main body, conveyance portions, barrier portions, and paths. The conveyance portions convey the raw materials in an axial direction. The paths each include an entrance and an exit. The raw materials, the conveyance of which is limited by the barrier portions, flow in from the entrance. The raw materials flowing in from the entrance flow through the paths in an opposite direction to a conveyance direction. The exit is opened in the outer circumferential surface of the screw main body at a position outside the conveyance portions in which the entrance is opened.

A screw machine includes an inductive heating device for processing of material to be processed. The inductive heating device is used to heat the material in a heating zone. In the heating zone, at least one housing portion is made of an electromagnetically transparent material at least partly, the material being non-magnetic and electrically non-conductive, whereas at least one treatment element shaft is made of an electrically conductive material at least partly. The inductive heating device includes at least one coil formed integrally with a component of the at least one housing portion, in particular in such a way as to form a hybrid component. During the processing of the material, the inductive heating device generates an alternating magnetic field that produces eddy current losses in the at least one treatment element shaft, the eddy current losses leading to a temperature increase of the at least one treatment element shaft.
