The diagram illustrates the process of producing instant coffee from raw coffee beans.
Overall, the production process consists of eleven stages, beginning with the harvesting of coffee beans and ending with the packaging of the final product into jars. The process involves several steps, including drying, roasting, grinding, mixing, freezing, and vacuum drying to prepare the coffee for sale.
In the first stage, coffee beans are picked by hand from the coffee trees. The beans are then spread on the ground to dry under the sun. Once dried, they are collected and roasted in a high-temperature oven to develop flavor and remove any remaining moisture. After roasting, the beans are cooled rapidly and ground using a hand-operated grinder. The resulting powder is then mixed with hot water and strained to separate the liquid from the solids.
In the next stage, the liquid mixture is poured into a freezing container to solidify quickly. After freezing, the frozen mixture is ground again using a hand grinder. The ground coffee is then dried in a vacuum to remove any remaining water. Finally, the dried coffee is packed into jars, making it ready to be sold in markets.
