Spray Drying
« on: May 28, 2010, 07:01:31 AM »
I will be glad if someone can clarify my doubts -

1)  Can hygroscopic materials be spray dried ?
2)  Does the pH decrease during the spray drying process ?
3)  Will an alkaline pH have any any effect on the moisture content or the property of the product ?

I just conducted a pilot trial to recover the sodium salt of MCA from water. The liquid solution taken for the spray drying had a pH of 9 ( a mistake while neutralizing). Hence the powder product obtained was comparatively wet and sticky and more importantly I lost a lot of product because it got stuck in the chamber.

Would lowering the pH to 7 solve these problems ? Will it lower the moisture content in the output powder ?
