High Viscosity Processor - Design Principles

LCI offers high viscosity processors with the following design configurations.

Rotor Designs

Fixed Clearance used in combination with transported flow blades for medium viscosity applications and dilute feeds to increase evaporative capacity
Transported Flow provides positive transport for viscous materials which do not flow by gravity—usually those of 50,000 cp or more. The exact blade configuration will vary depending on the product characteristics.

Rotor Orientation

Vertical is used for all high viscosity applications. The vertical configuration provides reliable, efficient processing of viscous and fouling fluids. Units are designed with no bottom bearing.

Vapor Flow

Counter-current flow is normally recommended for final concentration of viscous streams.
Co-current flow permits processing super-heated/flashing feed streams and is often used as a pre-concentrator for vented extruders.

Thin Film Evaporators

An LCI agitated thin film evaporator (TFE) or wiped film evaporator (WFE or "wiffe") provides short residence time and open, low pressure drop configuration, allowing continuous, reliable processing of many heat sensitive, viscous, or fouling materials without product degradation.

Short Path Evaporators

Short path evaporation is excellent for gently processing heat sensitive, high boiling products. Short path evaporation perfectly complements LCI's thin film evaporation technology program, allowing us even greater capability to provide the right solution for your separation problems.

D-Velpac® Evaporator

Provides an inexpensive and effective means to evaluate thin film evaporation within your facilities at pilot plant scale.

Thin Film Dryers

LCI Thin-Film Dryers concentrate slurries, suspensions, and solutions such as catalyst or salt solutions and crude glycerin with indirect heat transfer and mechanical agitation of the thin product film under both vacuum and positive pressure conditions.
