Abstract

En skrue-ekstruderanordning for behandling av sterkt avgassende materialer omfater en hovedekstruder (1) for egentlig materailbehandling, en materialmate- og utslippsanordning (4, 5) og en avgassingsanordning på hovedekstruderen for utslipp av gasstrøm fra fordampningsdelen (14). For at gasstrømmen skal forgrenes til minst tre separate strømmer (19, 20, 21) omfatter avgassingsanordningen en første avgassingsport (13) og minst to avgassingselementer som er anordnet motsatt i forhold til hverandre og radiell i forhold til hovedekstruderen (1) og er anordnet mellom fordampningsdelen (14) og den første avgassingsporten (13) og som fortrinnsvis er konstruert som hjelpeskrue- ekstrudere (7, 8) som åpner seg radiell inn i hovedekstruderen.
