Fresh bagasse from the sugar mills is dried either by solar or
mechanical drying until moisture content is reduced to about 10-12%.
Dried bagasse is conveyed to the chopper where chopping is done
until it is reduced to mesh size of 8-10 mm.
Chopped bagasse is now brought to the silo by a pneumatic conveyor.
Mechanically, this is conveyed to the batch weigher to determine
its weight. Resin is then sprayed evenly at about 2.5-4% of the
whole mixture. The mixture is dropped to the mat layer where the
caul plate is placed underneath to catch the mixture. Additional
anti-fungi and anti-termite solutions is sprayed to the mixture
to arrive to a desired moisture content.
The mixture is now ready to be pressed to the pre-set thickness
by the use of a hydraulic press and steam-heated plates. Pressure
is applied to achieve the desired thickness of the board.
The pressed boards are cut into a specific standard size of 4
feet (1.22 meters) wide by 8 feet (2.44 meters) long.
F. CLASSIFYING AND CURING
The newly-formed boards are inspected and classified by the Quality
Assurance personnel based on the standards set by the Company
and the industry. These are then cured for a number of days based
on the thickness to stabilize the boards.
Boards which passed the QA inspection are carefully piled in wooden
pallets at different quantities per thickness of the boards.
