I have a problem when I used spray drying to solidify a polymer solution. The yield was too small because solidified polymer like a spider's web in the drying chamber, I tried to reduce the solid content and temperature but the yield is still too small.
Hello Syaiful,
I was reading a patent while ago discussing this problem that I if water atomized along with with the solution. polymer deposits in the liquid distributor and in the atomization apparatus are prevented. Please read the whole story here
Method for spray drying polymer emulsions and solutions

1. Dilute your polymer solution, increase both the temperature and spray pressure.
2. You can also try with freeze drying method.
All the Best.
Thanks to Dr. Amin Shavandi,
Thanks to Dr. Arun Karthick, but 1st sugestion had been tried, however the result was similar
Dear Mr Choiri,
From my point of view, you have some problems with the suspension properties and spray drying parameters. The wall deposition of the spray dried material always influences the yield. Suspension viscosity and the inlet temperature are important parameters for the wall deposition.
Best regards,
Fatih.
Dear Mr Bastan
And then, what should I do? is it to decrease the viscosity and reduce the inlet temperature?
