LCI thin-film dryers are widely used throughout the process industries to convert liquids, slurries, and pastes to free-flowing solids in continuous, single-pass operation.
LCI supplies two types of thin-film dryers — Vertical or Horizontal. For some applications, the two are combined in the Combi Dryer™.
|
Both LCI Vertical and Horizontal Dryers are indirectly heated, either by steam or hot oil. Both can be operated either semi-batchwise or continuously, at atmospheric pressure or under vacuum. LCI drying systems are compact as a result of very high heat transfer rates. |
- Ideal for processing heat sensitive products
- Short residence time
- Low product “hold up”
- Heated surface fully self-cleaning
- Heating and cooling available in single system

Wet product fed through the inlet nozzle is conveyed steadily by the rotor blades along the heated dryer wall in a thin film, normally several millimeters thick, preventing buildup and continuously exposing every particle of the product to the heated surface. Vapors pass countercurrently to the product flow and exit the dryer through the feed nozzle, as configured above. Moisture levels from a few tenths of a percent up to 5%+ can be achieved. Residence time is typically controlled between four and fifteen minutes. |
