The coffee roaster is used to bake coffee beans that have been shelled and peeled, removing excess water from the coffee beans. The roasted coffee beans has an aroma, and the taste will be good after grinding into powder. The coffee roaster has two sensors that measure the temperature in the baking chamber and the temperature at the tuyere so as to adjust the baking temperature in the drum. In addition, the roasting machine has four motors, which control the mixing, roller, cooling fan, and collection of coffee beans skin.
