Patent abstract
A modular spiral belt constructed of a series of hingedly interconnected belt modules arranged in a helical stack. The modular spiral belt includes outer side plates that include openings for airflow and inner side plates that are solid to block airflow. The openings may include valves for selectively opening and closing the openings. A locking mechanism may lock two tiers together. A hold down may apply pressure to prevent destacking of the belt, or a guide may be disposed with the helical stack for preventing destacking.
