The diagram illustrates the process of producing coffee from raw beans to the final packaged product.
Overall, the production of coffee involves a series of linear stages, beginning with harvesting coffee beans and ending with packing the finished coffee into jars. The process includes drying, heating, grinding, mixing, freezing and vacuum-drying stages.
At the first stage, ripe coffee beans are picked by hand. They are then spread out and dried under the sun to remove moisture. Once dried, the beans are roasted at a high temperature. After roasting, they are rapidly cooled to prevent further cooking.
Next, the cooled beans are ground into small particles. These ground beans are mixed with hot water, after which the mixture is strained to remove solid residue. The resulting liquid is then frozen. Subsequently, the frozen coffee extract is ground again into smaller pieces.
In the final stage, the ground frozen liquid is dried in a vacuum chamber, where all remaining water is removed. The final coffee powder is then packed into jars and sealed, ready for distribution and consumption.
