Infrared Pre-Heating Oven
This process serves to superficially dry the product before entering the oven; this treatment is indispensable because it avoids fouling with the product of the first roller entering the oven
Pre-drying of the product takes place through a series of infrared lamps of the type with medium fast waves, and an air circulation system with a fan exhaust
With controls
Main structure of the infrared oven: painted-steel frame, length 2.000 mm
Preheating system with infrared emitters: 10 infrared lamps of the type ceramic
Lamp replacement is done by opening the upper frame and extracting the full support of the lamp; to avoid contact with the product on the lamps there are provided suitable spacers
Installed power: 100 kW
Upper part of the oven opening at 45° with pneumatic pistons
Exhauster: 1 x fan exhauster on the top of the hood allows the evacuation of the moist air
