At ORO Caffè we use an innovative tailored roasting system. Traditional hot-air roasters force heated air under the coffee beans which immediately exits the screen or perforated plate through the after burner and smokestack.
In our plant, on the other hand, the hot air generated by the methane burner is used again after the first roasting cycle. This not only gives the coffee beans a more intense aroma but also creates an ecological value. By using the same hot air several times, we can save almost 60% of the energy consumption as there is no need to constantly reheat the system.
