Turba-Film Evaporation Process Achieves Amazing Results! Turbulent thin film principle evaporates Time-atTemperature sensitive m a t e r i a l s . . . in seconds. T h e T u r b a - Film® C o n t i n u o u s Evaporator employs a totally different concept o f evapora tion. M a k e s h e r e t o f o r e ex t r e m e l y difficult e v a p o r a t i n g processes simple and rapid. A c t u a l l y e v a p o r a t e s m o s t sub s t a n c e s i n a few s e c o n d s ! Here's how the patented TurbaFilm Evaporator w o r k s . The sub stance to be evaporated is fed into the evaporating section. Here it is whirled against the wall by controlled-speed rotor blades. This forms a thin turbulent film, centrifugally held to the wall, which spins in a gravity flow through the cham ber and out . . . completing the process. The vapors rise into the s e p a r a t i n g section where rotor blades beat out any entrained drop lets a n d force them back through the evaporating section. So thorough is this Turba-Film process that no substance requires re-circulation . . . the desired con centration is achieved in one pass! So fast is the Turba-Film Evap orator action that proper heating is done in seconds. Eliminates hydro static head. No localized overheat ing. Eliminates vapor binding on heat transfer surface. Maintains high over-all heat transfer coeffi cient of from 100 to 500 ! Colors, flavors, potency, odor, nutritional a n d other valuable prop erties are retained to a much higher degree. Particularly important for Time-at-Temperature sensitive ma terials such as: pharmaceutical " m y c i n s , " vitamins, malt extracts, juice concentrates, etc.

Because such a small quantity is in process at any given time, the Rodney H u n t Turba-Film Evapor a t o r p e r m i t s quick c h a n g e - o v e r from one product to another. Makes cleaning and maintenance easy with m i n i m u m p r o c e s s hold-up. Allows constant quality control. The turbulent thin film principle permits concentration t o very much higher viscosities a n d solids con tent than is practical w i t h conven tional equipment. The Turba-Film Evaporator will satisfactorily con centrate heavy viscous materials in excess of 20,000 centipoises. Turba-Film processing has also proved strikingly effective for deoderizing, stripping and for evapora t i o n of w a t e r or s o l v e n t s f r o m solutions of organic compounds. When distilling, the residues are discharged continuously and are not subjected to re-circulation and "cooking." Where only the vapors were wanted, Turba-Film has dis tilled up to 9 9 % of t h e material! The Turba-Film Evaporator (Luwa Process, Switzerland) is particularly important for applica tions which are difficult or uneco nomical to process conventionally. Please consider our complete en gineering staff at your disposal for consultation on any possibleTurbaFilm application. We h a v e the facil ities for making test runs in our pilot plant: or we c a n provide a portable laboratory u n i t for u s e in your own plant. Models available i n ranges from 40 to 2500 lbs./hr. of water evapor ation. Stainless steel construction. Mail this coupon for free color brochure explaining t h e Turba-Film Evaporator in detail.
