Abstract:
1. An Extruder system for extruding a fluid comprising: a basic element having ,successively arranged along a longitudinal axis, at least one supply device, at least one mixer device, at least one extrusion die, and a discharge nozzle with a nozzle outlet, wherein a housing which is part of the mixer device and extrusion die extends along the longitudinal axis and wherein a suction head is arranged at the nozzle outlet, wherein an inner surface of the housing and an outer surface of a rod which extends within said housing define a cavity extending along said longitudinal axis, wherein the cavity defines, within the mixer device, a mixing chamber, and within the extrusion die, a discharge chamber, wherein the discharge chamber opens into the nozzle outlet and wherein, at an end of the mixer device which is proximal to the supply device, an input for a fluid to be extruded into the mixing chamber is provided, wherein the housing further comprises inlets for a transport fluid which lead into the mixing chamber and wherein the transport fluid is, in said mixing chamber, a gas under pressure wherein the inlets are fluidly connected to at least one device that produces a pressurized transport fluid and wherein the inlets are arranged such that the transport fluid completely or partially surrounds the fluid to be extruded to reduce friction between the fluid to be extruded and the housing and that the transport fluid and the fluid to be extruded flows essentially parallel in direction of the nozzle outlet of the fluid to be extruded, and whereby the fluid to be extruded is discharged from the extruder system by pressure or by suction and pressure of the transport fluid.
