A coffee roaster machine operates using the chemical properties of green coffee beans and transforming them into roasted coffee products. It’s this machine that produces the final taste of coffee. The operation occurs in a circular or cylindrical grill, called the roaster. The roaster is a gas heated/electrical/wood tool that is in permanent rotation so that the grains are roasted uniformly and without being burned.
The heat, which is distributed through a furnace, consists of refractory bricks and slabs; the green coffee beans arrive from a hopper at the top of the unit. They are then introduced into a horizontal cylinder, lined with metal blades that will agitate for the duration of the roasting. When coffee is introduced into the cylinder, the temperature is between 180 ° C and 220 ° C. The arrival of a cold mass of material makes the temperature drop to 120 ° C. It will rise to 200 ° C in 15 minutes. After roasting, the coffee beans change colour, and decrease in volume: 150 kg before roasting, it drops to 120 because of grain water loss.

The most common roasting machines come in two basic types: drum and hot-air.
Main advantages of the coffee roaster
The main advantage of this machine is that it can accommodate various quantities of coffee. As the process of this equipment is quite simple (it’s all about heating the raw coffee beans), it’s possible for it to operate continuously without any human intervention. Furthermore, the price of this machine is quite affordable. However, a good understanding of this machine is necessary, and a perfect heating temperature has to be found; if it’s too hot, the beans will be damaged. Not enough heat, and the beans will be tasteless.
