Fluidized Bed Dryer DF
Working principle The PETKUS Fluidized Bed Dryer was developed to gently and flexibly dry seed after chemical treatment. During the coating process large amounts of liquid are sometimes sprayed leading to moisture pickups of up to 5%. Fluctuating weather conditions or high humidity also influence moisture content thus making grain or seed drying an inevitable step to preserve germination ...

Fluid Bed Dryer How Fluid Bed Dryer Works for .
Fluid bed dryer works on a principle of fluidization of the materials. In fluidization process, hot air or gas flow is introduced through the bed of solid particulates. This gas or air will move upwards through the spaces between the particles. As the velocity increases, upward drag forces on the particles increase and at a stage become equal to the gravitational forces beneath. Hence the bed ...
