Typically, the sheet pressing process carried out by
two rotating roller surface. A new innovation shows that
one of the main rollers, especially the base for pressing can
be replaced by a material that acts as the base sheet when
pressed by a roller that rotates (shoe press). In this way
then pressed into a broader nip than the conventional. This
causes an increase in water discharge capacity during
pressing. Drought sheets can reach 35-50% more than 5-
7% from the conventional one.
4.1.3 Paper Machinery: Drying Section
Application of advanced technologies to control
dryer showed energy savings of 4500 lb of steam / hour,
reduced energy consumption, reduced maintenance costs,
and increase productivity. Decrease the use of air to the
dryer can be done if you apply a closed hood system and
optimize the heat recovery system. Heat recovery system
can be increased from 15% to 60-70% when coupled with
proper treatment.
The temperature is often controlled with ventilation
pocket of high air temperature is more than the minimum
requirement. As a result a lot of wasted energy disposed.
When the temperature is lowered to 180-195 ° C, there will
be a saving of steam around 1000 to 2000 lb / hr. Some
actions to take advantage of waste heat will be very helpful
energy saving program. The use of stationary syphon in the
dryer will save energy of 0.85 MMBTU per ton due to
improved drying efficiency. The use of mechanical
recompression to reuse superheated steam into the dryer,
can save energy by 50%. While the use of heat pump
system for utilizing waste heat in the dryer, will provide
energy savings of 0.4 MMBtu per ton of paper. The heat
from the air vents can also be utilized to heat other
