Abstract

A conveying system for pneumatically conveying plastic granulate comprises a feed location, at which the plastic granulate is fed into a conveying line by pressurized conveying gas, a target location, in conveying connection with the feed location, for moisture contained in the conveying gas, and a condensation tempering unit, which is arranged along a section or sections of the conveying line, for making the conveying line such temperature to at least partial condensation of moisture contained in the conveying gas to form a sliding film on an internal wall of the conveying line.
