Hulling

Hulling is an important process in the coffee industry that involves removing the outer husk or parchment layer from coffee beans. This step is crucial to ensure the quality and taste of the final coffee product. During hulling, specialized machinery is used to separate the husk from the beans, resulting in green coffee beans that are ready for further processing.

There are different methods of hulling coffee beans, including wet and dry processing. In wet processing, the coffee cherries are first pulped to remove the outer skin, and then fermented to loosen the parchment layer, which is finally removed through hulling. Dry processing, on the other hand, involves drying the cherries with the husk intact, and hulling is done once the beans have dried completely.

The hulled coffee beans are then sorted and graded based on various criteria such as size, weight, and defects. This ensures that only the highest quality beans make it to the market. Hulling is a crucial step in the coffee production process that plays a significant role in determining the flavor, aroma, and overall quality of the final coffee product.
