A dryer for drying a food-substance foam mat which is transported on a perforate conveyor belt, with the mat pierced at the locations of perforations in the belt. The dryer includes: a drying chamber through which the mat and belt travel; a gas heater-blower system for developing a unitary flow of heated gas in the chamber, which flow is in a direction generally toward one side of the travel path for the belt and mat; and a corrugated perforate web which completely spans the drying chamber, and which functions to form, from the unitary gas flow mentioned, plural spaced-apart streams of gas that are directed toward the travel path.
