Abstract
A shaft reactor for treating bulk material, including granular bulk material, in particular for the continuous post-condensation of PET, PEN or PA in the solid phase. A uniform product flow without significant decrease of the usable contents of the reactor and a decrease of the bulk pressure in the reactor is achieved by use of internals which are uncomplicated to fabricate. Internals are arranged in the reactor which comprise at least one ring and a plurality or ribs.
