THERMAL CONDITIONS FOR THE SILO STORAGE O F WHITE SUGAR AND DRIED PULP PELLETS (REVIEW)

This paper describes the technical phenomena occurring in the storage in tower silos of white sugar and pulp pellets, both hygroscopic mater ials. It looks at the physico-technical principles of moisture incorpo ration and presents the isotherms of sorption. In the case of sugar, d istinctions must be drawn between free moisture, bound moisture and in ternal moisture, only free moisture being amenable to removal. The aut hors list the technical possibilities of conditioning and provide an o verview of the volume flow data found in the literature for silo venti lation.
