Claims

[Scope of utility model registration request]

- The material to be dried is supplied to the upstream end of the rotating drum, and the material to be dried is dried by the rotation of the masticating drum and the thermal energy of the gas supplied therein, and one product is delivered from the downstream end of the rotating drum. In a rotary ventilation dryer designed to take out the
The upstream part of the rotating drum serves as a preheating part, and the central and downstream parts thereof serve as a drying part, and the preheating part is a sealed double cylindrical body consisting of an inner cylindrical helmet, an outer cylindrical wall, and a downstream end wall. A louver is provided in the drying section, a high temperature gas supply port is provided for supplying high temperature gas into the double cylinder, and a high temperature gas supply port is provided on the downstream end wall of the double cylinder, facing into the louver. A rotary ventilation dryer equipped with a preheating section using indirect heating, which is characterized by forming a nozzle and providing a medium-low mother gas supply port for supplying medium-low temperature gas into the louver of the drying section.
