Abstract

See full text

A dryer for drying granulated material for use in pharmaceutical products. The dryer includes a plurality of stationary drying chambers, each having its own feed conduit. A common material removal device receives discharged, dried granules from each of the drying chambers. A changeover valve has a plurality of outlets and provides a path from the supply source of the granulated material to a charge port on each of the drying chambers, so that each drying chamber is charged sequentially. Air ducts provide flows of warmed air. The main air duct provides a main airflow, a relatively large volume of air, to an air inlet in each of the drying chambers. The auxiliary air duct provides a lesser volume of air to the feed conduit of each drying chamber, to aid in moving the granulated material out of the feed conduit and into the drying chamber.
