ABSTRACT:
Both indirect and counterflow direct heating are utilized in a dryer to achieve improved efficiency with a reduced tendency to char or damage the treated material. A horizontal drum has a first segment of aluminum and a second section of stainless steel and is disposed within a heating chamber which is divided into two sections by a baffle. Hot combustion gases are introduced to the chamber and flow to the end of the heating chamber to the rear of the drum and enter the drum. The gases counterflow through the drum in a direction opposite to material moving through the drum to exchange heat. The gases remove moisture from the material and exit the drum into a preheat zone of the chamber where the moisture laden gases condense on the drum's surfaces. The exhaust gases then proceed up two stacks. The interior surfaces of the heating chamber and the preheat chamber are insulated to increase thermal efficiency.
