Abstract: A cooker includes a bottom heater and a top heater defining therebetween an axially controllable cooking space for receiving therein an uncooked food product and for cooking the food product. A prepared food tray is adjacent to the cooking space. A dragger with a dragging surface is configured to displace the cooked food product from the cooking space to the prepared food tray. An integrated drive system is configured for controlling an axial dimension of the cooking space and a horizontal displacement of the dragger. The drive system may include: a belt drive; a cooking space shaft, and a cooking space clutch for selectively connecting and disconnecting the cooking space shaft from the belt drive; a dragger shaft, and a dragger clutch for selectively connecting and disconnecting the dragger shaft from the belt drive; and a controller for controlling operation of the belt drive and the clutches.
