Mann and Hummel Filter Private Ltd manufacture Drying Hoppers. Mann and Hummel Filter Private Ltd is DIN ISO 9001 certified. This product is used in the plastics-processing industry. The Drying Hoppers are made exclusively of aluminium or stainless steel. Drying Hoppers designs are distinguished by a good mass flow and optimal air distribution with a wide selection of residence time, thereby ensuring optimized drying. From a process engineering viewpoint, adapted insulation guarantees the effectiveness of the drying process, i.E. Particularly for drying at high temperatures of 120 - 180 degree, the thickness of the insulation on the outer shell [including the cone and cleaning opening] is increased and hopper components such as the air distributor and double cone are heat-insulated.
