VetterTec Spray Dryers
VetterTec offers spray dryers based on 30 years
of experience and 150 references world wide in
the food and chemical industries. The special
know-how in the design of the atomizers provides
high reliability and a sophisticated solution to
give the particle characteristics for the desired
application.
The VetterTec spray dryer is designed to dry
liquids to powder by means of an atomizer.
The atomizer is placed in the top of the drying
chamber and forms the liquid into small droplets
before spraying them into a hot air stream.
The hot air is heated by gas, steam or other heat
sources and then enters the drying chamber by
means of a sophisticated air distribution system.
The temperature is precisely controlled by monitoring the inlet feed and outlet temperature.
As soon as the atomized wet particles come into
contact with the hot air the major part of the
water evaporates in a few seconds. The remaining part of the water will evaporate as the
powder is carried with the air stream through the
drying chamber. At the end the dried powder will
be separated from the air by a cyclone and/or
a filter system. Downstream the dryer can be
equipped with fluid beds, coolers and agglomerators, to further condition the powder prior to
the packaging unit.

VetterTec Spray Dryers
Fields of Application
Spray drying is a very gentle drying and is mainly used to dry heat sensitive products. VetterTec is focusing the brewery, ethanol and chemical
industries and is able to build spray dryers from pilot plant size to industrial units.
Alcohol/Ethanol Industry:
Fodder yeast
Lignin
Atomisation is provided by centrifugal wheels, pressure nozzles or twofluid nozzles. This range of systems allows the specific particle size
requirements to be met for each application. Direct or indirect heating
systems are supplied depending upon the industry standards for the
product. Inlet temperatures may range from 100°C for very heat sensitive products to 750°C for some inert chemicals.
Closed circuit and self-inertised dryers are supplied to allow organic
solvents to be dried and to meet the environmental specifications.
Different chamber configurations are used along with a range of residence times to provide the desired particle size and moisture content
in the finished powder.
Agglomerated products are produced by using integrated fluid beds,
fines recycle systems and external fluid beds. These powders are widely
used in the food industries.
