An apparatus for roasting coffee beans comprising:

• a housing,
• a roasting chamber presenting a bottom opening and a top opening,
• an air driver configured to drive air inside the roasting chamber through the bottom opening of said roasting chamber,
• a heater positioned below the bottom opening of the roasting chamber, said heater being configured to heat the air driven inside the roasting chamber,
• the air driver and the heater being positioned inside the housing and the housing comprising a hot air outlet hole designed to enable the passage of hot air from the housing inside the bottom opening of the roasting chamber,
• a smoke and particles collector configured to collect smoke and particles from the top opening of the roasting chamber,
• the roasting chamber being removably mounted to the housing, the bottom opening of the roasting chamber cooperating with the hot air outlet hole of the housing and the top opening of the roasting chamber cooperating with the smoke and particles collector when the roasting chamber is mounted to the housing,
• a chamber locking assembly for locking the roasting chamber to the housing in a removable manner, wherein said chamber locking assembly comprises:
• a bottom device configured for connecting the bottom opening of the roasting chamber to the hot air outlet hole of the housing, said bottom device being configured to receive a bottom of the roasting chamber and to hold the roasting chamber,
• a top fastening device for connecting the top opening of the roasting chamber to the smoke and particles collector, said top fastening device comprising:
• a translatable connecting conduit configured to connect the top opening of the roasting chamber to the smoke and particles collector, said translatable connecting conduit being translatable without rotating, and
• a fixed holding device configured to hold the translatable connecting conduit in at least three positions:
• one first upper position where the translatable connecting conduit is hold held by the fixed holding device and disconnected from a top of the roasting chamber,
• one second intermediate position where the translatable connecting conduit is connected to the top of the roasting chamber, and
• one third lower position where the translatable connecting conduit is detached from the fixed holding device.
