with Turba-Film Evaporator and Rodney Hunt Spray Dryer

Typical of many drying processes done rapidly and efficiently with Rodney Hunt equipment is the production of powder from liquid concentrate as illustrated.

The TURBA-FILM® Evaporator is a unique application of the falling film principle. It operates over a wide range of temperature, pressure and viscosity. Sensitive materials are so briefly exposed to heat that there is no impairment of original qualities. Distillation, cooling, stripping, deodorizing and de-aeration, as well as concentration, are accomplished in a single pass. The thin film, the small quantity in process at any time, and centrifugal separation eliminate difficulties due to foaming and frothing. TURBA-FILM evaporating capacities run from 40 to 5000 pounds per hour.

The Rodney Hunt Spray Dryer delivers powder which is homogeneous, highly soluble, sized to specification, and in the form of particles or dust-free hollow beads. Even slurries can be handled advantageously. Common heat sources such as gas, oil and steam are used successfully and economically.

Rodney Hunt engineers make available to you the experience of years in the engineering of many evaporator and spray dryer installations. Rodney Hunt equipment is built in Rodney Hunt shops with complete modern facilities to highest standards of workmanship.

Schematic drawing of Continuous Drying System shows Rodney Hunt Extractors, Turba Film Evaporator and Rodney Hunt Spray Dryer for converting liquid to soluble powder. Extrac­tion produces a true solution with low solids. The Turba-Film Evaporator reduces the solution to desirable higher solids. The Rodney Hunt Spray Dryer reduces the concentrated solu­tion to a powder with the final desired low moisture content.
