Fast and efficient drying of chemical on paper / board is must and improves quality of Coating. Early drying of Coating Chemical restricts binders to penetrate in the paper board. So drying should be earliest after chemical coating In our System, Air is filtered by filter Pads then heated by steam or hot oil through Heat Exchanger and then hot Air is sent to Hot Air Applier. The vapours created by applying hot air to wet paper/board is sucked by another suction blower and this process is repeated four times. The Capacity of Blowers and Hot Air depends upon paper board deckle machine speed and amount of coating chemical applied. This system is safe and running cost is very cheap in comparison to I. R system and the system is maintenance free.
