Disclosed is a birotational barbecue apparatus comprising a cooking chamber (1), a transmission apparatus (3) provided between an outer housing base plate (4) and a cooking chamber base plate, a barbecue pipe (5), a driving electric motor (6) and a roasting support (2). The transmission apparatus (3) comprises a speed reduction gear (3.1) and a fork (3.2); the roasting support (2) comprises a bottom tray (2.1) and a combined carrier (2.4); a lower face of the bottom tray (2.1) is provided with a snap-fitting structure snap-fitted with the fork (3.2); the combined carrier (2.4) comprises a driving gear (2.42) and an annular upper cover (2.43); an outer side of an inner wall of the annular upper cover (2.43) is provided with a meshing gear meshing with the driving gear (2.42); the transmission apparatus (3) further comprises a fixed position shaft (3.4); the fixed position shaft (3.4) is fixedly provided on the outer housing base plate (4), is axially connected to the upper cover (2.43) of the combined carrier (2.4) and is used for blocking the rotation of the upper cover (2.43) and blocking the radial movement of the fork (3.2) and the speed reduction gear (3.1). When barbecuing, the fork (3.2) drives the roasting support (2) to rotate, making the driving gear (2.42) of the combined carrier (2.4) rotate around the inner wall of the upper cover (2.43) meshed therewith, producing a rotational motion around its own axis. The birotational barbecue apparatus can be used for various barbecue apparatuses having a cooking chamber of any shape and any starting means.
