Hopper Package
The AEC/Whitlock BCHE drying hopper package features a process air blower, heater and
controls for each hopper in your system. BCHE also offers a process air heater removed from the
dryer and mounted at the hopper. The temperature controller is mounted at or on the drying
hopper.
Important!
The main dryer may or may not have a process blower.
Check your drying system for specific options.
The BCHE drying hopper package design allows one dryer to generate dehumidified air for
multiple hoppers. Materials can be dried by a single dryer at different temperatures. BCHE can
also serve as a stand alone hot air dryer for non-hygroscopic materials when an optional ambient
air filter is installed to filter air entering the system.
Note: The BCHE package utilizes individual power drops to each hopper.
