Abstract
Unidryer combines the advantages of gas infrared and air dryer. In the Unidryer, gas infrared only takes care of energy transfer by radiation to the wed. Air float nozzle of highest technology takes care of mass transfer and web. Air float nozzle of highest technology takes care of mass transfer and web stabilization.
Therefore, Unidryer can reach 65% energy efficiency which is higher than traditional infrared systems (Electric 35/40%, Gas 35/55%) or air dryer (35/40%), and can minimize running cost. As Unidryer has very high water evaporate rate (150 kg H2O/m2/hr, if installed on one side of the web and 250 kg H2O/m2/hr, if installed face to face), space required for machine can be reduced.
Unidryer is the missing keystone that all machine builders have been looking for to design faster, more compact and efficient paper machine.
