Abstract:Coffee is one of the most consumed beverages all over the world. Making coffee starts with grinding beans, which means dividing the beans into small particles. The size, form and distribution of those particles have a significant influence on the coffee extraction process, and a constant size, form and particle size distribution is therefore essential for the repeatability of the brewing process. A strong presumption exists under experts in the coffee industry about the repeatability of the grinding process of well known, commercially available coffee grinders. Multiple tests were performed to see if these presumptions are correct. The results of these tests were analysed with Minitab by performing a regression and variance analysis. Based on the test results, multiple redesigns are proposed to improve the grinding process.
