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.

A conveying system for pneumatically conveying plastic granulate by means of humid conveying gas, having
- 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, comprising
- a condensation tempering unit, which is arranged along one of a section and sections of the conveying line, for making the conveying line such temperature for the at least partial condensation of moisture contained in the conveying gas to form a sliding film on an internal wall of the conveying line, wherein the condensation tempering unit is arranged along the conveying line along a conveying direction between the feed location and the target location.
A conveying system for pneumatically conveying plastic granulate by means of humid conveying gas, having
- a feed location, at which the plastic granulate is fed into a conveying line by pressurized conveying gas,
