Abstract
Systems and methods for drying or bonding materials are described. A material to be dried or bonded may be passed through a through air dryer (TAD) (or other dryer). Some of the air output by a TAD may be recirculated to be passed back through material. As the air is recirculated, it is heated and mixed to a desired temperature for drying or bonding. A separate hot air injection system may heat ambient air and/or air exhausted by the TAD and inject the heated air into the recirculated air.
