Abstract (en)
[origin: ES8401614A1] There is disclosed a tunnel oven which comprises a base, a guide provided on the base to guide the movement through the oven of wagons bearing product to be treated in the oven, side walls connected to the base and a roof connected to the upper ends of the side walls in order to define a treatment chamber. Each wagon comprises a base for supporting product to be treated, and wheels supporting the wagon base and engageable with the guide. The base of the oven includes a trough containing a liquid, and each wagon has a skirt depending from the wagon base which defines an under chamber below the wagon base and which has its lower edge continuously immersed in the liquid as the wagon moves through the treatment chamber. A train of wagons can thus pass through the oven, with the under chamber of each wagon sealed-off from the oven treatment chamber, whereby the wagon bases, or product carried thereby, effectively form a lower face of the treatment chamber. The skirts depending from each wagon base are formed by metal blades which extend downwardly from the longitudinal and transverse end walls of the wagon bases.
