Abstract

Det blir beskrevet en fremgangsmåte for forbedring av masselyshet ved anvendelse av en kombinasjon av en distribuert total hvitlutpåfylling under trinnene ved påfylling av varmlut, ekstra varm lut og koking i en satsvis prosess og lave koketcmpcraturer under kokctrinnet. Den høye totale hvitlutpåfyllingen er i området mellom 15% ÅA og 35% ÅA, mens koketcmperaturene er mellom 150 ~ 168°C.
