  • Method to prepare extruded particles by breaking with an air stream
    Patent number: 5147593
    Abstract: Extruded particles (H), especially as a precursor for pharmaceutical pellets are prepared by extruding a doughy mass in the form of a strand (G) into a gas stream (E) in which it is predried and also broken by the gas stream (E). A lance (40) is employed for the extrusion which extends through a treatment chamber (12) and carries extruder nozzles (80) opening transversely of the general flow of gas (E). A pressure gas nozzle (96) fed intermittently with pressurized air is directed to the opening range of each extruder nozzle (80).
