In this co-current parallel flow dryer with a top mounted nozzle atomization system the coarse spray droplets are dried slowly while gently falling down the long residence time tower-like chamber. The dried particles are seperated by gravity in the enlarged conical section into a coarser main fraction and fines collected from the exhaust air.

The coarse fraction can be cooled by air introduced into the lower part of the cone, or further dried / cooled in a vibrating fluid-bed.

The fines can be recycled to the atomization zone for incorporation by agglomeration, or to the liquid feed.

Product: Can produce free-flowing, dustless powders consisting of coarse, individual beads.
