spray dryer vs. drum dryer

spray dryer vs. drum dryer

Hi,
 Why we use of spray dryer?!
 It is not economical we use of spray dryer .Because feed of spray dryer is a 'slurry' or a 'solution' ,thus it is better we , firstly , dewater the feed with mechanical means and then use of a drum dryer that its feed is paste or viscose liquids.
  Is it right?
 Does somebody knows online information about dryers?(especially spray dryer, drum dryer , flash dryer and fluid bed dryer)

RE: spray dryer vs. drum dryer

In my view , drum dryers are used for large throughput of granulated products. Spray dryers on the other hand can be designed even to handle throughputs in the range of 0.5 - 1 MT / hr. Spray dryers produce fine powder ( spray dried milk powder, detergent powder , some fine chemicals etc. ). Spray dryers are not that efficient handling highly viscous products.

Dear Mohtogh,

Ask Niro Atomiser. If they cannot tell you the benefits of spray drying, then no-one can.

Cheers,
John.
