Description
Drum dryers convert viscous liquids and pastes into dry powders, flakes, or sheets
Standard atmospheric model consists of a single heated drum supported on trunnions that turn in journal or roller type bearings
Feed materials are applied to drum with splash or dip devices, or with applicator rolls
Heat conducted through the drum wall evaporates moisture from wet product film during partial revolution of drum
Single layer applications dry to a lacy sheet or flake
Multiple layer applications dry to uniform thickness and density with minimum dusting
Can be equipped with "satellite" applicator rolls spaced around periphery of drum to eliminate void areas, permitting drying between successive layers of fresh material, and forming thick consistent product sheets gradually
Mechanical support skids are available for single drum dryers
Features
Standard sizes as large as 60" x 192" with 251 square feet of drying surface
Includes liquid or paste feed and adjustable knife
Contains long-life roller bearings, compact hollow-bore gear drives, and fully automatic drum and roll gap control
Turnkey system comprises pre-concentrating evaporators, PLC controls, drum temperature regulation, mezzanines, size reduction, sifters, and mechanical or pneumatic conveyors
Five (5) independently driven "satellite" applicator rolls available
Screw conveyor option available
Benefits
Dryer reduces drying process to one smooth operation
Self-cleaning drum ensures 100% of product is dried and recovered
Linear actuators, transducers, and PLC provide closed loop feedback for dynamic on-the-fly positioning
Auto gap control option eliminates need for manual adjustment of drum and roller gap
