The process diagram illustrates the production of coffee.
Overall, it is clear that the production of coffee involves 12 steps, which can be grouped into three main stages: harvesting and drying coffee beans, processing, and packaging. Notably, several changes in both temperature and water content occur throughout the procedure.
The first two steps involve picking and drying coffee beans under the sun. Subsequently, the beans are roasted and rapidly cooled before being ground and mixed with hot water. The mixture is then strained, frozen, and ground into smaller pieces. Afterward, the frozen liquid is dried in a vacuum. Finally, the product is packed into jars and made available for sale.
Temperature and moisture control play a critical role in this process. Initially, water content is reduced through drying and roasting. After being combined with hot water, the mixture undergoes further moisture removal by freezing and vacuum drying, ensuring that the final product is completely dehydrated before packaging.
