Coffee Cherry Milling

Green Coffee Milling

Milling involves removing the outer layers of the fruit from the coffee cherries (this specific step is called hulling). Optionally, the beans are polished and/or sorted based on density and size of the bean.

Various machines are used throughout the hulling, polishing, and sorting processes. People operating these machines are at risk of being injured by the machinery.

Surprisingly, dust from dried green coffee beans has been shown to cause irritation and allergic reactions in a majority of workers.
