Shahdad Kamfiroozi

Seyed Mohamad Javidan Thanks for the source but this article is about the nozzle. I have information about the rotary sprayer (Wheel atomiser spray) for design. The shape of the evaporation chamber will be different when used with the wheel atomiser spray.

Article SIMPLE PROCEDURE FOR DESIGN OF A SPRAY DRYER.

Please go through this article, may be helpful to you.

Chandrakant Genu Dalbhagat Thank you so much it was very useful and practical. Share other content, if any.

If you have developed the sprayer, you can simulate the spraying operation using a CFD-based software and then conclude the desired diameter and height of the reactor you're looking for.

Rahul Whig

Shahdad Kamfiroozi I am currently facing the same problem. Have you been able to determine the height and width of the spray dryer?

Dear Rahul Whig

Yes, it can be determined.

The type of sprayer must first be specified to determine the distribution diameter range. Then, considering the cone angle of 60 degrees and also considering the co-current for the inlet flow to the chamber and the direction of spraying, the ratio between height to diameter in the evaporation chamber is considered between 0.6 to 1. However, it should be noted that to determine the maximum radius of the evaporation chamber when using a wheel atomizer, there is a relationship between the inlet volume flow to the wheel atomizer and the diameter of the disk.
