Abstract

En kontinuerlig kokare för framställning av kemisk cellulosamassa utav cellulosahaltig flis innefattande ett kokarkärl med en övre del som är ansluten till en toppseparator, och vilket kärl är åtminstone delvis fyllt av den cellulosahaltiga flisen och en lut; en toppseparator belägen åtminstone delvis i nämnda övre del som har en nedre flisinloppsöppning, en flistransportör, en sil invid transportören, en övre flisutmatningsränna, och ett lututlopp mot en sida av silen mittemot transportören, och en flisinloppskanal som sträcker sig in i kärlet och har ett första funktionstillstånd i vätskeförbindelse med flisinloppsöppningen och ett andra funktionstillstånd, där flisinloppskanalen matar ut direkt till kärlet.A continuous digester for producing chemical cellulose pulp from cellulosic chips comprising a digester vessel having an upper portion connected to a top separator, which vessel is at least partially filled with the cellulosic chips and a liquor; a top separator located at least partially in said upper portion having a lower chip inlet opening, a chip conveyor, a screen adjacent the conveyor, an upper chip discharge chute, and a liquor outlet towards a side of the screen opposite the conveyor, and a chip inlet channel extending into the vessel and having a first operating state in fluid communication with the chip inlet opening and a second operating state in which the chip inlet channel discharges directly to the vessel.
