Bean roasting machine

A bean roasting machine in which hot air is jetted from a central bottom of a cone-shaped roasting pot in a direction oblique to a radial direction of the roasting pot to stir and roast beans, the bean roasting machine comprising:

• a heater device as a heat source for roasting;
• and
• a roasting blower that sends high-pressure air into the heater device and sends the air becoming a high temperature by the heater device into the roasting pot, wherein
• the heater device is disposed directly below the central bottom of the roasting pot, an air blowing outlet of the heater device opens upward and is directly connected to an air intake inlet formed in the central bottom of the roasting pot,
• an air intake inlet of the heater device is located on a side surface of the heater device and is directly connected to a blowing port of the roasting blower,
• a wire mesh is installed at an upper end portion of the air intake inlet formed in the central bottom of the roasting pot and prevents bean dregs and foreign materials from falling directly into the heater device from the central bottom, and
• a small hole is formed at a lowest surface of a space provided outside the upper end portion and prevents water infiltrating the roasting pot from entering the heater device.
