Horizontal Reactor on Movable Floor Stand
Horizontal Reactor Floor Stand in Upright Loading
Position
Horizontal Stirring Position
The reactor above and below has a five gallon
capacity, and is used for stirring horizontally.
Pneumatic controls on the left can tilt the system
upright to open
the bottom
drain valve.
The product
is filtered and
collected in a
heated sample
collection
vessel below.
This system is
used for mak-
ing fabric from
biomass. Most
synthetic fabric
is made from
oil.
Stirring biomass such as straw or grasses is not
easy to do in a vertical reactor. A new technology
has been developed to do it horizontally. In the
system pictured to the left, a
one-liter reactor can be dis-
connected to tilt vertically
for loading or tilt horizon-
tally for stirring. A heavy-
duty stirring motor and
double anchor stirrers are
used. Another option would
be to tilt upside down for
discharge. A 4848 controller
monitors the temperature
and pressure and controls
the stirring speed. A flexible
mantle heater (not pictured)
is used to obtain tempera-
tures up to 350 °C. Maxi-
mum pressure is 1900 psig
for this system.
