- W.D.E. is situated
at Terni, 150 km north of Rome, Italy.
- GOUTTESOLARD BOIS and
W.D.E. jointly designed the special
features of this
kiln.
- The airtight kiln is
clad in stainless steel, has 2 km of
weld and took 3 months to build. external
size 4,0 x 4,0 x 18,0 m
Drying process :
- After loading, the
internal pressure is reduced to 100 millibars
( atmospheric pressure is 1000 mb). At this pressure,
water will boil at 40 degrees centigrade.
The kiln is heated to well above this
temperature. The extraction of water, in
the form of vapour, is quick and efficient.
- The speed of drying
is adjusted by varying the vacuum
relative to temperature
and is
automatically computer-controlled.
