Vibrating Fluid Bed Dryer

The Komline-Sanderson Vibrating Fluid Bed Dryer (VFBD) is a direct drying system used to thermally process a wide variety of materials.

The VFBD uses direct heat transfer to process many different pastes, cakes, powders, and granules in a highly controllable manner. In addition, the VFBD “fluidizes” the material by a combination of vibration and air that passes upward through it, allowing for uniform heat and mass transfer.

Uniform product moisture content is achieved by passing treated gas through a perforated plate assuring intimate mixing of the gas and process material. As the treated gas passes through the wet material the moisture is removed and carried away to be treated in a cyclone and baghouse. The dried final product is conveyed to the dryer discharge. Clean-up and maintenance of a VFBD is simple and easy.

The VFBD provides the following advanced features:

  • Negligible particle entrainment
  • Uniform air flow and gradual removal of moisture
  • Ease of maintenance
  • Long equipment life
  • Compact design across a wide range of sizes
  • Ability to handle temperature sensitive material
  • Residence Time Control
  • Can operate batchwise or continuously
  • Easy to Clean
  • Energy Efficient
  • Cost Effective

The K-S VFBD can be used in a variety of applications such as heating, drying, and cooling. The VFBD can be used to process pharmaceutical, food, nutraceuticals, chemicals, pesticide, plastics, fibrous material, biomass, and more. Material with a minimum particle size of 1 mm can be fed and processed in the VFBD.

The K-S Vibrating Fluid Bed Dryer (VFBD) is a fully enclosed design that prevents contamination from outside the environment. Material enters the dryer by the feed inlet, via the vibration force material is conveyed along the drying zone in a continuous movement. Treated gas is passed through the perforated plate to transfer the energy and liquid. The treated gas is discharged from the top of the VFBD while the dry material is discharged at the product outlet of the unit.
