Abstract: A heat transfer system includes a conveyor belt having air permeable outer and inner side walls and forming a conveyor stack having a plurality of tiers and a central space with a volume. A first portion of the volume and a first plurality of tiers are in a first sub-chamber and a second portion of the volume and a second plurality of tiers are in a second sub-chamber. The system further includes generating means which: produces, in the second sub-chamber, airflow in a horizontal direction towards the conveyor stack and in a horizontal and radial direction across the second plurality of tiers to enter the second portion of the volume; and draws, in the first sub-chamber, the airflow in a horizontal direction away from the conveyor stack and in a horizontal and radial direction to exit the first portion of the volume across the first plurality of tiers.

Abstract: A method for controlling tension in a belt of a conveyor system. The method involves: driving the belt along a path from an intake region to a discharge region using an intake motor adjacent the intake region and a discharge motor adjacent the discharge region; measuring a tension in the belt using an intake belt sensor that moves with the belt proximate the intake region to generate an intake belt signal; measuring a tension in the belt using a discharge belt sensor that moves with the belt proximate the discharge region to generate a discharge belt signal; monitoring the intake and discharge belt signals; and adjusting at least one of the intake motor and the discharge motor based on the intake and discharge belt signals to maintain the tensions in the belt within a pre-defined range.
