Chaff Collector
A Chaff Collector is an important piece of equipment used in coffee roasting. When coffee beans are roasted, they shed a paper-like skin called chaff. The Chaff Collector catches and stores this waste material to keep the roasting area clean and safe. Think of it like a vacuum system that captures floating coffee bean shells. Without this tool, the loose chaff could create mess, affect air quality, or even pose a fire hazard. Most commercial coffee roasting setups include some form of chaff collection system.
