The invention relates to an apparatus (1) and a method for more convenient roasting of coffee beans. The apparatus (1), which is provided for roasting coffee beans, comprises: a chamber (10) in which coffee beans can be received for roasting, wherein the chamber (10) comprises an opening (13), and a device for roasting the coffee beans received in the chamber (10). The chamber (10) is movable with respect to a movement axis into different positions, wherein these positions comprise a roasting position, preferably a bean reception position, and a bean discharge position, wherein in the roasting position the device is arranged to roast the coffee beans received in the chamber (10), in the bean reception position, if present, the chamber (10) is arranged to receive, via the opening (13), coffee beans for subsequent roasting in the roasting position, and in the bean discharge position the chamber (10) is arranged such that the coffee beans can be discharged via the opening (13) from the chamber (10).

A bean roasting system includes a roasting drum, an agitator, and a door. The roasting drum has an inside surface extending from a back end to a front end. The agitator has blades mounted to an axial shaft. The axial shaft has an anterior end portion. The door is mounted rotationally relative to the roasting drum and includes a glass plate and a bearing assembly. The glass plate provides visual access to contents inside the roasting drum when the door is closed. The bearing assembly includes an outer housing and an inner bearing. The outer housing is mounted to the glass plate. The inner bearing defines a receiving hole that receives and supports the anterior end portion of the axial shaft when the door closed.
