“…Inner diameter of pulley and outer diameter of the pulley are calculated using eq. ( 9) and ( 10 𝐷 𝑘 = 𝐷 𝑝 + 2 × 5.5 (10) After obtaining the diameter of the pulley, then determine the length of the belt required to transmit power from the motor to the drive shaft. The calculation of the size of the circumference of this belt can be used in eq.…”

“…Several parameters should be considered to obtain the best roaster design, such as the drum dimensions and material [7], temperature, roasting time, efficiency in induction heating roasters [8], the number of holes, and burner diameter [9]. Some commercial coffee roasters using electric heaters for the home industry are widely used [10]. However, they still have some disadvantages; high energy consumption and expensive [6].…”

Bengkulu Province is one of Indonesia's top coffee producers. However, coffee processing is still done traditionally. Therefore, modern processing is required, particularly in the roasting process, which is vital in deciding the flavor of the coffee. This study aims to design, build, and test a low-energy coffee roaster with a capacity of 2 kg. The components of a coffee roaster are designed according to the demands and relevant standards, such as drum volume, drum material, shaft size, pulley size, belt, burner stove, and motor parameters. The coffee roaster is then tested by altering the distance between the fire holes to 10, 15, and 20 mm with a diameter of 3 mm, as well as varying the rotating speed of the drum to 60, 65, and 70 rpm and varying the coffee varieties, namely Robusta and Arabica. The testing of coffee roasting equipment with a capacity of 2 kg went smoothly. The results show that the ideal distance of the stove burner hole to attain 200 °C was discovered at a distance of 10 mm and a distance of the stove to the drum of 10 mm with a time of 17.24 minutes. For Robusta and Arabica coffee beans testing, the light roast should be roasted for 10 minutes. The medium roast requires 15 minutes of roasting time. And the dark roast requires a 20-minute roasting process. Furthermore, the rotating speed of the drum has little influence on the character of roasted coffee beans

Coffee is one of the most common and favorite beverages that many people have been consuming around the world. A smart coffee roaster uses a smart sensor and controller to operate the roaster and to get the best consistency and also accuracy of the resulting roasted coffee. The current paper discusses the electricity, design, and Artificial Intelligence (AI) needed to make the best version of a smart coffee roaster. The electronic system consists of a sensor, controller, and actuator. Sound and temperature sensors are the ones that are used within the device; meanwhile, the most commonly used controller is a microcontroller. Actuators are the driving motors of the roaster drum. Ergonomic, aesthetic, and user comfort are the primary keys needed to make a good design. The AI application detects the ripeness of the coffee seeds and the “crack” sound detection. Based on the comparison of previous studies that have been done before, readers are expected to identify the required needs of specifications within a smart coffee roaster.
