The digram illustrates the various stages involved in the production of instant coffee from raw coffee beans.
Overall, the process consists of two main phases; the preparation of coffee beans (which includes harvesting, drying, and roasting), and the conversion into instant coffee (which involves gringding, extraction, freezing, and packaging). It is evident that the procedure requires several and chemical processes before the final product is ready for consumption.
The process commences when coffee beans are harvested from plants. Following this, the beans undergo a drying process, during which they are spread out and heated to remove moisture. Once the beans are dry, they are transferred to a roasting machine where they are heated at high temperature. Subsequently, the roasted beans are cooled and then filtered to separate any unwanted particles. At this stage, the beans are ready for next phase.
In subsequent phase, the roasted beans are ground into a fine powder before being mixed with water in extraction tank. Here, the coffee liquid is separated from grounds. The next step involves freezing this liquid at extremely low temperatures, after which it is ground again into granules. Finally, these granules are packed into containers, and the instant coffee is ready for distribution and sale.
