Abstract

En sentrifuge (500) for å skille et fødemateriale i faste og flytende bestanddeler, hvilken sentrifuge omfatter en transportør (540) som er dreibart montert i et dreibart hus (520), hvor transportøren har minst én skovl (572) og det dreibare hus har et separasjonsområde som omfatter et bassengområde og et tørkeområde mellom transportøren og et dreibart hus, idet anordningen er slik at nevnte fødemateriale, ved bruk av sentrifugen, under innstrømning i denne har en aksialhastig- het som i alt vesentlig er parallell med dennes lengdeakse, hvor fødematerialet strømmer gjennom det indre av nevnte transportør (540) ved en rotasjonshastighet som tildeles dette ved hjelp av nevnte minst ene skovl (572) før behandling i nevnte separasjonsområde, idet nevnte minst ene skovl også tildeler nevnte fødemateriale en radialhastighet mens dette beveger seg med en aksialhastighet, slik at fødematerialet spres utover tørkeområdet langsetter og inntil lengden av den minst ene skovl, idet en del av transportøren (540) er tilbøyelig til å slites ned av fødemateriale som beveger seg fra den minst ene skovl og utover tørkeområdet, kjennetegnet ved at nevnte transportør omfatter en monteringsinnretning (580) som (1) gir transportøren mekanisk integritet og (2) anordner et parti som kan ofres til nevnte slitasje, idet anordningen er slik at sentrifugens mekaniske integritet gjennom ofring av nevnte del, ved bruk i alt vesentlig forblir uskadd.
