  4. Infrared Pre-Heating Oven

    1. 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

    2. The 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

    3. Main structure of the infrared oven: painted-steel frame, length 2,000 mm

    4. Preheating system with infrared emitters: 10 infrared lamps of the type ceramic

    5. 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

    6. Installed power: 100 kW

    7. Upper part of the oven opening at 45° with pneumatic pistons

    8. Exhauster: 1 x fan exhauster on the top of the hood allows the evacuation of the moist air

  5. Ptfe Conveyor Belt

    1. Driven PTFE conveyor belt to support and guide the material through the IR pre-heating

    2. PTFE glass belt type AG60 mesh 6 x 6 mm

    3. Centering system for the conveyor belt

    4. Tensioning system for the conveyor belt

  6. Tunnel Oven
