Description
The Gryphon Biomass Hot Air Belt Dryer, Model A.318, is an industrial-grade gas-fired recirculating counter-current air dryer designed for drying biomass materials such as hemp. With a water evaporation rate of approximately 213 lbs/hr, this dryer processes 3,000 lbs of wet biomass per 24 hours and outputs around 1,000 lbs of dry product at a moisture level of 7% to 11%. The dryer section measures 18’ long by 3’ wide and is equipped with a 23.625" cleated feed belt, condenser coils, and a CTS cooling tower and condenser unit.
The unit features a 1.5 MMBTU natural gas burner with all required gas train valves, firing controls, and Honeywell fire eye safeties, along with supplemental electric heaters in each section. Airflow is powered by a 2500 SCFM blower with Allen Bradley PowerFlex 753 VFD and six PowerFlex 525 VFD drives for precise control. Full PLC automation allows for control of air volume, temperature, cycle time, and includes automated washing of the chambers, air filters, and belt.
