Coffee processing technologies

After harvesting, coffee cherries need to be processed in either dry or wet method to have the fruits, known as mucilage, which cover the beans, removed. When the skin is removed to leave only the mucilage, it is referred to as the pulping process.

The beans are then separated by weights and sizes by rotating drums or screening sieves. After the beans are dried and graded, they are ready for roasting. Sometimes, the different beans are blended to create desired taste. When it comes to the wet process, fermentation of the coffee beans in essential. Therefore, specialized coffee fermentation tanks will need to be used to achieve this.

Since coffee’s characteristic flavor and aroma only develops until beans are roasted, roasting is an essential step in the process. After roasting, coffee beans are usually ground in roll mills. The primary goal of grinding is to produce the most taste in a cup of coffee, while the type of grinding determines how fast the coffee can release its flavors.

The quality of coffee beans or ground coffee is quickly diminished by oxygen in the air; oxygen breaks down the precious aromas in the coffee, and the flavor becomes flat. To guarantee as far as possible that the flavor of the coffee enjoyed by the consumer is as good as when it left the factory, coffee beans or ground coffee is very often vacuum or soft-vacuum packed, so that no air can get in.
