Abstract

Prosessanlegg og fremgangsmåte for automatisk flertrinnsfremstilling av kitinderivatet kitosan, ut fra et bio- logisk skallmateriale som særlig kan være rekeskall. Anlegget har en tank (2) med en åpning (16) øverst, et varmeelement (40), en pumpe (24) for sirkulasjon av væske, en innvendig trommel (8) med perforert vegg for rotasjon under anleggets drift, dyser (68,72) for å spre væske inn i trommelen, og programmerbare styreorganer for den automatiserte drift. Fremgangsmåtens prosesstrinn bygger på at prosessanleggets ene kombinasjon tank/trommel inngår som hovedelement i samtlige trinn, idet disse omfatter opp- varming under rotasjon og sirkulasjon, vasking/nedkjøling, syrebehandling, ny vasking/nedkjøling, lutbehandling, ny vasking/nedkjøling og tørking ved tilfør- sel av tørkeluft. Nitrogengass tilføres fortrinnsvis under syre- eller lutbehandlingen for å redusere oksygeninnholdet i den masse som behandles.
