| Agitated Thin
Film Evaporators |
Agitated Thin Film Evaporators or
Wiped Film Evaporators are used for
concentration, distillation or stripping
of heat sensitive, viscous or fouling
products
|
| Features |
- Residence
time of a few seconds with
a narrow spread, an important
feature for heat sensitive
products
- Required
evaporation can be achieved
in a single pass, avoiding
product re-circulation and
possible degradation.
- Suitable
for viscous products
Scale formation on the heat
transfer surface is avoided
due to the intensive agitation
in the liquid film
- Excellent
turn down capability
Low product holdup-ideal for
hazardous applications
- Operating
pressure from atmosphere down
to 1 mbar and operating temperature
up to 350 °C.

Applications |
- Vacuum distillation
of bulk drugs, intermediates, fine
chemicals, glycols, used lubricating
oils, fatty acids and its derivatives,
rubber chemicals, amines and esters
- Concentration
of bulk drugs, pesticides, oleoresins,
Para formaldehyde, enzymes, organ
extracts, plant extracts, milk products,
juices and sugars
- Pesticides,
plasticizers, monomers from polymers
- Devolatalization
of polymers
- Recovery
of contaminated solvents, products
from residues

| Rotor
Designs |
We offer
the following four rotor designs to
suit specific application needs :
- Fixed Clearance
with straight blades
- Zero Clearance
with hinged blades
- Zero clearance
with roller elements
- Fixed
Clearance with screw elements
|
| Fixed
Clearance with straight blades |
- Most common
design that covers a wide range
of evaporation, distillation and
stripping applications
- No moving
parts
- Easy to clean
- Suitable
up to 1 mbar pressure
|
| Fixed
Clearance with screw elements |
- Used for handling
highly viscous products like polymer
melts
- No moving
parts
- Easy to clean
- Suitable
for pressures up to 1 mbar
|
| Zero
Clearance with hinged blades |
- In an evaporator,
this rotor design squeezes product
from small quantity of residue or
contaminants
- Suitable
for pressures up to 1 mbar
|
| Zero
clearance with roller elements |
- Suitable
for gentle distillation of heat
sensitive products
- Suitable
for pressures up to 1 mbar
