May I ask about the application ranges of rake-type vacuum dryers and vacuum conical dryers? Thank you.

What are the application ranges of the rake-type vacuum dryer and the vacuum twin-cone dryer, for drying materials that are in powder form with particle sizes of 20 to 100 microns? Thank you.
Reply to 1# ztao0916: The limitation of the rake dryer mentioned by the original poster is that it has a mechanical seal installed in a horizontal position; in the event of a leak, oil can get mixed into the product. It has a high mixing power, making it suitable for use with thick and viscous materials. The double-cone dryer is the exact opposite.
Reply to 2# Chemical Equipment Expert: It was a silly mistake with the material details; apologies.
Thank you, I’ve learned it; it’s very helpful
The stirring function unique to vacuum rake dryers accelerates the evaporation of moisture in the material, making them suitable for viscous materials. Steam can pass through the shaft of the rake type, increasing the heat transfer area of the equipment; compared to the double-cone type, its drying efficiency is incomparable.
