ABSTRACT:
This invention relates to an improved pulp drying process for indirectly drying beet pulp which is characterized by the inclusion of a steam heated dryer of the type wherein the process steam used in the drying operation remains isolated from the vapors driven off the pulp so that the latter remain clean, uncontaminated and ideally suited for use in process heating. The invention also contemplates the removal of entrained solids from the evolved vapor prior to stripping the heat therefrom. A further refinement contemplates the inclusion of a preheating step wherein the pressed pulp is preheated preparatory to being dried.
