FILTER SYSTEM FOR A FLUID BED GRANULATOR/DRYER

摘要

A novel filter system for fluid bed granulator/dryer machines which utilizes pleated filter elements that can be stacked end to end so as to remove material from the exhaust air and wherein a number of filter elements can be mounted parallel to each other and end to end to obtain the desired filter capacity. In a first embodiment, the filters extend horizontally across the machine and in the second embodiment they extend it in a slanted plane across the machine. The filters can be cleaned by alternately providing reverse air flow through them.
