Riedhammer recommends the use of a dryer upstream the biscuit firing or the glost firing kiln, if a residual moisture of <0,5% at the kiln entrance cannot be assured.
The dryer is operated for the most part with waste heat from the kiln, a support burner provides, if needed, for a constant temperature of the air supplied.
The product is conveyed through the dryer on transport slabs.
The loading on the slabs is made in a single layer, in piles or with setters.
The dryer is installed directly upstream the kiln.
