“…Generally, the roaster consists of six main parts: the roasting drum, the outer frame of the drum with the coffee inlet and outlet hoppers, the main motor driver, the heater, the cooler, and the temperature controller [6]. 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].…”

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

“…In accordance with the opinion of Suryadi et al (2022), the roasting process with a roasting machine is carried out in a closed manner using a cylindrical tube given a rotary force. This aims to get even heat in the tube.…”

The purpose of this research is to design a rounding cylinder tube on a coffee roaster using an electric heating element that will be used to roast coffee. The roasting process also uses an electric motor to rotate the cylindrical drum so that the stirring process becomes even. The research was conducted using engineering methods including identification of problems, roasting machine design formulation, prototyping, functional testing, and performance testing. The data analysed are roasting capacity, roasting temperature and the need for electrical energy used. The results showed that the roasting capacity was 2.3 kg•h -1 . The serving of coffee for dark roast maturity levels can be ended when the temperature has reached a temperature of 201 °C. The need for electrical energy in the heater for roasting arabica coffee beans with a maturity level of a dark roast for 1 hour 54 minutes obtained an average value of 3.4 kWh, with the need for electrical energy for roasting arabica coffee beans which is 1.35 kWh.
