    • A low impact belt dryer is presented for drying pellets while minimizing high- energy pellet collisions that may create pellet dust or cause pellets to fracture. The dryer includes a vacuum chamber having multiple air knife assemblies that direct high velocity drying fluid towards the pellets and though a liquid-permeable pellet-impermeable belt to a vacuum port. The low impact dryer may also include a centrifugal dryer for dewatering the pellets before they pass though the vacuum chamber. The conveyor belt of the dryer may transport the pellets through multiple desiccation chambers where low velocity air is directed upwards though the belt to both dry and levitate the pellets above the belt. The dryer may also include a cleaning chamber for removing debris from the liquid- permeable pellet-impermeable belt.
