摘要

Raw material (8) is fed into the first section (a) where physical and/or chemical conversion results from shearing. In the second section (b), energy dissipation and compression take place. Post-expansion and off-gassing from the machine, follow in the third section (c). Recompression (d) against the outlet constriction (10) resistance, followed by cooling of the emerging product, complete processing. An Independent claim is included for corresponding equipment to carry out the process. Preferred features: At any stage, external liquid additives can be introduced. The machine has external heating. Gases and/or steam (9) evolved are used in preconditioning and/or machine heating. The outlet constriction is a matrix forming the product. The matrix is perforated. Alternatively an insert with annular or straight gap is used. Product leaving, is cut to length and/or textured by a pair of rollers.
