Conveyors, belt suction

Category 4 Food contact materials and articles from which, according to their intended use conditions, no mass transfer to food could occur. Examples are conveyor belts and roller covers, suction and pressure lines for filling or emptying tanks, seals for pipes, pumps, faucets and valves for drinking water. 

The surface of the used conveyor belt is linked to the surface of the produced web. For certain filter applications, it is necessary to have a smooth surface created by fine mesh belts. A suction box in order to transport the air through the belt is integrated into the conveyor belt machine. Since the attenuation air can hit the belt with high speed, also the suction air needs to handle these high speeds.
