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.

Compactor (100) for the “granulation” of plastic materials, the compactor (100) comprising a first zone or unit (101) for loading and distribution capable of being loaded with plastic material and distributing the plastic material loaded to other zones and/or units of the compactor (100); a second zone or unit (104) comprising a perforated spinneret (110) and at least one compacting roller (105) installed external to the spinneret (110), where the material is “granulated” by “sinterization” deriving from its forced passage through the perforations of the spinneret (110) under the action of the at least one roller (105); a third zone or unit for the forced feeding of the material, being provided at the at least one roller (105) comprising at least one rotating feeder auger (111) housed at least partially in a tubular housing (113).

A pellet made of dried, unfermented livestock manure has N, P and K values in the range of N: 3 to 7 g/kg, as ammoniac and organic nitrogen, P: 2 to 6 g/kg as phosphorus pentoxide and K: 2 to 6 g/kg as potassium oxide (g/kg). The pellet has a hardness exceeding 10 kg and has a shell composed of manure-base lignin. A press roll, including a hollow rotatable drum with a perforated screen, may be used in combination with an endless belt and a scraper to produce the pellet.
