The diagram illustrates the sequence of steps involved in the production of instant coffee, from harvesting the raw beans to packaging the final product for sale.
Overall, the process comprises a series of interconnected stages beginning with picking and drying the beans, followed by several thermal and mechanical treatments, and ending with the preparation of the dried coffee granules. Every stage is essential to transform the raw beans into a consumable product.
Initially, ripe coffee beans are picked and laid out under the sun to dry. Once sufficiently dried, the beans undergo roasting and are then rapidly cooled. After cooling, they are ground into powder. This powder is mixed with hot water to create a coffee solution, which is strained to remove any solid particles.
The filtered liquid is then frozen to facilitate the next step. The frozen mixture is ground again into finer pieces, after which it enters a vacuum-drying chamber. During this stage, all remaining water is extracted, leaving behind dry coffee granules.
In the final stage, these granules are packed into jars, sealed, and prepared for distribution to markets and consumers.
