6.2. Drying hopper (optional)
The material is dried in the drying hopper. The dehumidified air is forced through the material in
the hopper, collecting moisture in the process. The drying hopper must be dimensioned according
to its intended use to ensure that the final moisture content is attained. When the hopper is filled
for the first time or at the start of a drying procedure, the material in the hopper must be dried com-
pletely before material can be removed from the hopper for the first time.
When material is continuously removed from the hopper, material must also be continuously fed
into the drying hopper. The new (moist) material is fed into the drying hopper from the top and
slowly moves downward toward the material suction box. As the material moves upward, it is
dried until its final moisture content is attained.
To ensure proper continuous drying, we recommend that the drying hopper always is kept com-
pletely filled. Automatic conveyors, such as the models included in our delivery program, optimize
the automation of the material flow.
F
When material is continuously removed from the hopper, but no material
is continuously fed into the drying hopper (batch drying), the material le-
vel may not fall below 40 %.
Close the throttle valves.
