I’m currently looking at various drying technologies for a sludge-type material and am curious if anyone has any suggestions for other options to explore that I may not be thinking about.
This material is a bit challenging in that it is a sludge which is quite sticky. I also need to avoid over-heating it; temperature of the material being dried needs to remain below 95C. As if those two items weren’t enough, I also need to dry it to around 0.2% moisture content. The incoming moisture content is around 40% to 50% by weight.
I’ve eliminated a rotary drum or spray dryer due to the sticky nature of the sludge, as well as a flash tube dryer due to the temperature limitation and intensive energy requirements of that technology. I’m currently leaning toward, and moving forward with, a belt dryer - I’m awaiting initial feedback from several vendors to see how long of a belt I’ll need to get down to necessary moisture content.
I appreciate any suggestions or tips anyone may have.
PS: I didn’t see any tags currently available which would be appropriate for this topic; if a moderator would, please add a tag for “drying” - thanks!
