Conical Screw Dryer
Vortex conical screw dryer/mixer are ideal for vacuum drying a wide
range of applications, such as powders, granules, pellets, pastes, and
slurries. This type of drying equipment features a slow-turning screw
that gently lifts batch materials upward as it orbits around a conical
vessel. Materials carried to top of batch then cascade slowly back
down into regions opposite the moving of screw. The constant
exchange of materials between the heated sidewalls and center of the
blender accelerates the drying process.
A common issue in agitated dryers is the risk of product attrition or
generation of fines. This concern is well minimized in a conical
dryer/mixer because the blending action is thorough but low impact.
During the drying cycle, hot water, oil, or steam is recirculated through
the vessel jacket. Due to lower processing temperatures made possible
by the vacuum environment, there is a reduced risk of creating hot
spots on the vessel walls where product could bake.
Available in sizes from 50L through 30000L, the vertical dryer/blender
do not require a bottom support bearing to keep the screw steady so
discharge is virtually 100% complete. This “unsupported screw” design
also simplifies cleaning and maintenance. The pictured 500L model is
