COOKING MODULE FOR A LINEAR TUNNEL OVEN FOR BAKERY PRODUCTS, PASTRIES AND THE LIKE, AND LINEAR TUNNEL OVEN COMPRISING AT LEAST ONE SUCH MODULE

The cooking module for a linear tunnel oven for bakery products includes a cooking chamber having a hearth, in the form of a conveyor belt, that is mobile and permeable to a gaseous heat-transfer fluid, a roof, and a heating device in the hearth and on the roof to cook the products. The heating device in the hearth includes a plurality of orifices for blowing the fluid. The belt is mobile above a sliding surface having openings for the fluid to pass through, and is mobile between two positions, a convection position where the openings coincide with the orifices to let the fluid pass through, and a second position known as a radiation position, where openings are offset from these orifices, the surface forming a screen for the fluid blown through the orifices.
