The utility model discloses a stoving oven solves the unable adjustment of present stoving oven circulation wind speed, the problem that is unfavorable for toasting process control. The technical scheme who adopts is: stoving oven, including the box, the box is separated for toasting district and functional areas by the baffle, toasts through setting up supply -air outlet and the return air inlet intercommunication on the baffle between district and the functional areas to form the circulation wind channel, set up heating device and blast air circulating device in the functional areas, set up the deep bead in the circulation wind channel, position adjustment circulation wind channel through the adjustment deep bead cross wind section size, and then adjust the circulation wind speed, in order to control the process of toasting. Heating device is the brilliant hot plate of carbon, and the brilliant hot plate of polylith carbon is placed on the support frame and is set up wind direction under blast air circulating device, makes the heating more stable, toasting and setting up the material frame in the district, material frame below sets up air distributing plate, makes hot -blastly can get into in the clearance of toasting the material uniformly, still set up control system in the functional areas, make the control of stoving case more simple and convenient.
