Dehumidifiers for Fluid bed dryers

10/16/2007 2:54 AM

In high humid areas , high humid air used for drying of mass in fluid bed dryers could add more moisture to the mass and the drying time may increase.So what are the possibilities to install dehumidifier in the supply of FBD.?What type of dehumidifier could solve my problem?The cfm range is 2000-10000.

We use air handling units (AHU). There are two sections in the AHU, one for cooling (using chilled water) and another for heating (using steam). I guess the cooling section, causes the moisture to condense (which is drained out) and the heating section brings the temperature back up to what's required in the fluid bed. It also helps to drop the humidity further.

I believe in many cases, the air used for drying is compressed in a staged blower with intercooling to condense out the moisture. The final air is then heated to the desired temperature for process drying.
