The invention relates to an extrude unit for a dryer (2) for biomass, in particular slurry, wherein the extruder unit (1) has a surface section (4) for the biomass to pass through and a plurality of apertures (3), wherein the extruder unit (1) comprises a base support (5) which is connected by means of a connecting section (6) to a driving element (7) and can be driven by means of the driving element (7) about an axis of rotation (8) and relative to the surface section (4), wherein the base support (5) comprises at least one support arm (9) having at least one scraper blade (10) which during a rotation of the base support (5) follows the shape of the face of the surface section (4) facing the scraper blade (10). According to the invention the base support (5) also comprises at least one breaker element (11) having at least one scraper blade (10) which during a rotation of the base support (5) also follows the shape of the face of the surface section (4) facing the scraper blade (10) and during the rotation of the base support (5) effects a crushing of constituents contained in the biomass which are retained by the surface section (4). The invention further relates to a dryer having at least one corresponding extruder unit.

The manufacturing method includes a granulation step. The granulation step is a step of forming a plurality of granules by performing extrusion granulation on a granulation material using a granulation machine. The granulation machine includes a die. A plurality of through holes that allow the granulation material to pass therethrough are formed in the die. The plurality of through holes include first through holes having a first diameter, and second through holes having a second diameter that is smaller than the first diameter.

A device for producing pellets has a machine frame, a hollow outer cylinder mounted therein with a first axis of rotation and an inner cylinder, arranged in the outer cylinder, with a second axis of rotation, wherein a wedge-shaped gap is formed between an inner surface of the outer cylinder and an outer surface of the inner cylinder, the outer cylinder and/or the inner cylinder has radial holes for pressing through material, and a pivot arm is arranged on each of the two sides next to the inner cylinder, on which pivot arms the inner cylinder is rotatably mounted. Each pivot arm is moveably mounted on the machine frame in the region of both ends of the pivot arm.

The manufacturing method includes a granulation step. The granulation step is a step of forming a plurality of granules by performing extrusion granulation on a granulation material using a granulation machine. The granulation machine includes a die and a roller. A through hole that allows the granulation material to pass therethrough is formed in the die. The roller pushes the granulation material into the through hole while rolling on the surface of the die. In the granulation step, low-speed pushing in which the granulation material is pushed while the roller rolls at a first speed, and high-speed pushing in which the granulation material is pushed while the roller rolls at a second speed that is higher than the first speed are executed.

Various embodiments for an automated pellet press for automatically producing pharmaceutical pellets are disclosed herein.
