cluding cosmetics and food applications.
The vertical dryers operate differently
than hot-air and tray dryers.
Powder is stirred under vacuum,
which shortens the drying time by a
factor 2 to 10 compared to tray dryers.
Also, by reducing the necessary
handling, a similar shortening of the
total cycle time is achieved, says the
manufacturer. The improved heat
transfer during drying leads to a reduction
in utilities costs. Mechanical
mixing during drying leads to
an improved product homogeneity,
and the product emerges with residual
moisture values below 0.1%
where required, says the company.
Cure rubber parts
with this truck oven
The No. 860 is
a 500°F truck
oven (photo)
that is currently
used for
post-cure of
rubber parts.
Workspace
dimensions
of this oven measure 36-in. width,
36-in. depth and 60-in. height. The
oven uses Nicrome-wire heating elements
for a power of 34.8 KW to
heat the workspace, while a 2,000ft3/min.,
2-h.p. recirculating blower
provides horizontal airflow to the
workload. This truck oven features
4-in. insulated walls, a top-mounted
heat chamber, aluminized-steel interior
and exterior, plus front and rear
double doors. Other features include
safety equipment for handling
flammable solvents, including explosion-venting
door hardware and 325
ft3/min powered exhauster. - The
