LCI thin-film dryers are widely usedthroughout the process industries toconvert liquids, slurries, and pastes tofree-flowing solids in continuous, single-pass operation. LCI Thin-film Dryers havea short residence time and are veryeffective in processing heat sensitiveproducts, due to low “hold-up” and self-cleaning heating surfaces.

LCI supplies two types of thin-film dryers— Vertical or Horizontal. For someapplications, the two are combined in theCombi Dryer™. Both types are indirectlyheated, either by steam or hot oil. Bothcan be operated either semi-batchwise orcontinuously, at atmospheric pressure orunder vacuum. LCI drying systems arecompact as a result of very high heattransfer rates.

Why Use LCI Thin-film DryingTechnology?• Ideal for processing heat sensitive products

• Short residence time

• Low product “hold up”

• Heated surface fully self-cleaning

• Heating and cooling available in single systemVAPOR OUT

DRYPOWDERDISCHARGE

• Dilute feed materials dry to free-flowing solids in a singlepass — a one-step operation that eliminates severalprocess steps

• Thermal degradation of heat sensitive or hazardousproducts minimized by low residence time “indirectcontact” drying

• Fouling of the thermal surface eliminated by agitatingaction of specially designed pendulum blades

• Fully enclosed design to treat reactive, toxic and hazardoussubstances

• Complete recovery of solvents

Moving hinged blades spread the wet feed product evenlyover a heated wall. A highly agitated bow wave is formedin front of the pendulum blades. The turbulence increasesas the product passes through the clearance before enteringa calming zone situated behind the blades. The volatilecomponent evaporates continuously. The product layer isonly millimeters in thickness. The hinged pendulum bladesare designed to give a minimum clearance with the dryerwall to prevent fouling of the heating surface by product.The blades are not required to contact the heated wall.

Quality StandardsLCI thin-film drying technology is offered through our teamingpartnership with Buss-SMS-Canzler GmbH. Systems are manufacturedin ISO 9001:2000 quality certified facilities. Welding, design, andfabrication processes are employed according to ASME Section VIII,Div. 1 (U-Stamp), European vessel certification (PED), or otherrequired national codes.

Vertical Dryer

Horizontal Dryer

Wet product fed through the inlet nozzle is conveyed steadily by the rotorblades along the heated dryer wall in a thin film, normally several millimetersthick, preventing buildup and continuously exposing every particle of theproduct to the heated surface. Vapors pass countercurrently to the productflow and exit the dryer through the feed nozzle, as configured above. Moisturelevels from a few tenths of a percent up to 5%+ can be achieved. Residencetime is typically controlled between four and fifteen minutes.

• Continuous, fully enclosed processing

• Short residence time

• Low residual volatiles in final powder

• Superior mixing efficiency

• Self-cleaning of heating surface

• Low energy consumption

• Flexible through exchangeable rotor elements

• Minimal product hold-up
