FREMGANGSMAADE TIL RISTNING AF KAFFEBOENNER

摘要

The method permits control of the characteristics of the finished product. Gas, usually air and combustion gas, is heated to a temperature between 200 and approximately 240 degrees C. A mass of coffee beans in the form of a fluidised bed is suspended in the heated gas for approximately 2 minutes to approximately 10 minutes. The roasted coffee beans are then removed from the fluidized bed and cooled. The density of the roasted coffee beans is determined by the specifically selected roasting conditions.
