Spray Dryers (Galaxie)

KTV offers Spray Dryers with top quality material and accessories. We are also able to so help clients with advice, changes which may arise, updating existing equipment and transporting. Furthermore, we can provide product testing and drying facilities by third parties, equipment rental and personnel training, as well as auxiliary equipment according to each necessity.
 
Advantages relating to drying by atomization:
    • High performance, due to a very fast process (a few seconds)
    • The evaporation of the water contained, refrigerates the particles allowing the usage of high temperatures of drying air, without altering the qualities of the product.
    • Continuous process, constantly controlled.
    • Homogeneous production.
    • Excellent presentation of the product.
    • Installation operated by just one worker.
    • Easy automation.Installation may operate 24 hours a day.

SPRAY DRYING PROCESS

The liquid product is contained in the Feed Tank (1) where from it is driven by the Pump (3) through a Filter (2), the tubing and other accessories to the Atomizer (5).
 
The furnace Burner (8) and Chamber (7) supply the necessary heat to raise the temperature of the air which, forced by the Blower (15), flows through the Disperser (10) and uniformly spreads around the Atomizer disk (5), delivering the spray.
 
As the spray clashes with the hot air, drying takes place almost instantaneously on account of particle size.
Part of it being solid (product in a predetermined concentration) it falls in powder form into the Drying Chamber (11) and is aspirated by the exhaust fan, taken along the interconnection tubes (16) to the Cyclone (13) where the powder is separated from the air and extracted as the finished product, which passes through a Rotatory Valve (14) to be packaged.
 
The separated air escapes to the atmosphere after passing through the Scrubber (24)-(25) that allows recovery and recycling of the product and at the same time, prevents pollution.
