Descriptions
The Fluidized Spray PFSD is one of the most successful designs of spray dryers ever developed.It is used to dry a wiety of products many of which are extrem difficult to produce in powder form using conventional drying technologies.
The PFSD combines fluidization and spray drying technologies, enabling the size and structure of particles to be easily controlled.Therefore, the PFSD is often used as a spray dryer agglomerator or spray dryer granulator. Drying is completed
while very low powder important feature which makes this concept ideal for producing heat sensitive products in dried form.
Technological Advantage
1.Produces free flowing powders in agglomerated or granulated form.
2.Produces powders having a very low content of small particles(dustless)
3.Dries many thermoplastic and hygroscopic products that are problematic in other designs.
4.Ideal for heat sensitive products as particle temperatures are kept low throughout the drying process.
5.Drying is completed at low outlet drying temperatures, giving high energy utilization efficienies.
Applications
Chemicals
Detergents, Dyestuffs, Inorganic and organic salts, Pesticides, Tannins
Pharmaceuticals
Analgesics, Antibiotics,Blood plasma,Enzymes,Vitamins
Polymers
e-PVC,Styrene copolymers,UF, PF resins
Food products
Coffee, Dairy products, Eggs, Fermentation products, Flavours Malt extract, Maltodextrine, Soup mixes, Vegetable proteins(hydrolysed), Yeast
Device Structure and Composition
A. Atomizer
Nozzle or rotary atomizers are used to spray the feed liquid
into droplets.
B. Air disperser
A roof-mounted design controls the air flow pattern in the
drying chamber.
C. Hot air system
Provides hot air for drying. Incorporates oil,gas,steam,and
electrical heating units.
D Drying chamber
Cylindrical chamber with a fluid bed mounted in the conical
base.
E Exhaust air system
Separates airborne particles from the drying air leaving the
drying chamber.Cyclones and or bag filters are used.
F Powder handling
In pneumatic or vibratory systems, or vibratory systems, or
externally mounted fluid beds.
