The interior hood plate will be made of 2mm Corten A. The air duct will be made of 3mm Corten A, nozzles will be made of 6mm stainless steel. Framework is constructed from rectangular steel tubes by welding. When hood is assembled, a special assembly tool will be used to make sure that the arc line formed by nozzles keeps a certain distance with dryer surface. Between the exterior casing plate and the interior casing plate is the insulation of centrifugal glass fiber with density 48kg/m3, thickness: 75mm. The two halves of hood can be opened and closed by cylinder under the assistance of a series mechanism like supports, slide rails and pulley in case the sheet threading and hood cleaning is required. The control used to compress air is hand-operated valve, control panel of cylinder and metallic pipeline from control panel to cylinder belong to the scope of supply.
