This creation proposes an electric coffee roaster for coffee beans, which mainly has a base of an electric drive device; an electric heating device provided on the base, the electric heating device has a hollow shell, and the inside of the hollow shell forms a In the heating space, there are through holes in the front wall of the hollow casing, and a plurality of electric heating units are arranged around the inner side wall, so that the electric heating units generate heat toward the heating space; and a baking rotatably arranged in the heating space of the electric heating device瓮, the neck of the baking 瓮 extends out of the through hole at the front end of the hollow shell, and the bottom end of the baking 连结 is connected to the electric drive device to be driven to rotate. With this, the coffee bean electric roaster can achieve the purposes of safe heating, precise temperature and time control, prevention of heat loss, and easy assembly and replacement of roasting tincture.
