A coffee supplier in MN was looking to improve its dust collection equipment for its roasting process after some of its equipment was damaged in a fire. At this roaster’s facility, coffee is roasted in a rotary drum where hot air is passed over the beans. During the roasting process, the outer layer of organic material called chaff is burned off. Some of the chaff is then vented out of the roaster drum along with the hot air. Without having a pre-filter, the ESP (electrostatic precipitator) would clog up quite rapidly, requiring excessive cleaning and maintenance. Searching for a better solution, the roaster chose to install a 700 CFM GPC Dust Collector from Aerodyne.
