Abstract
When working on something, coffee is our best companion. Drinking coffee while engaging in activities can help boost our energy. This is due to the caffeine in coffee. Generally, coffee can be enjoyed by brewing it or making it into candy. But what if there is another way to enjoy coffee, not by brewing or making it into candy, but by consuming it directly? This can be achieved by heating coffee beans until they turn into powder. Heating can be done at various temperatures, ranging from 100°C to 130°C. The heating process involves placing green coffee beans in a 1-inch iron pipe and heating them for 10 to 15 minutes. During the heating process, the steam produced from the heated coffee beans is filtered using a distillation process. Distillation is used to filter the steam from the heating process and the remaining powder. After the heating process is complete, the powder collected from the distillation process will be gathered according to the temperature variations. This collected powder will then be tested both by direct consumption and by brewing, as with regular coffee. During the heating process, a mass transfer occurs. Saat sedang mengerjakan sesuatu, kopi merupakan teman terbaik kita. Minum kopi saat melakukan aktivitas dapat membantu meningkatkan energi kita. Hal ini dikarenakan adanya kafein di dalam kopi. Pada umumnya cara menikmati kopi dapat dilakukan dengan diseduh atau dijadikan permen. Tetapi, bagaimana jika ada cara lain menikmati kopi, bukan dengan diseduh atau dijadikan permen, melainkan langsung dikonsumsi. Hal ini dapat dicapai dengan cara memanaskan biji kopi sampai menjadi serbuk. Pemanasan dapat dilakukan dengan suhu yang beragam, mulai dari 100oC – 130oC. Proses pemanasan dilakukan dengan menaruh biji kopi hijau di dalam pipa besi 1 inci dan dipanaskan selama 10 – 15 menit. Selama proses pemanasan terjadi, uap hasil pemanasan biji kopi disaring menggunakan proses destilasi. Proses destilasi berguna untuk menyaring uap dari hasil pemanasan biji kopi dan serbuk yang tersisa dari proses tersebut. Setelah proses pemanasan selesai, serbuk yang tersisa dari proses destilasi akan dikumpulkan sesuai variasi suhu pemanasan. Serbuk yang terkumpul tersebut di uji coba kembali baik dengan cara langsung di konsumsi maupun diseduh seperti kopi pada umumnya. Selama proses pemanasan berlangsung terdapat proses perpindahan massa yang terjadi.
