Heat-treating equipment for roasting food products, including a tub for receiving the product, which is associated with a stirrer and a heat source. The tube includes two vertical, coaxial and hollow cylinders, the inner cylinder defining a first wall, and the outer cylinder defining a second wall of a space having a crown-shaped cross-section, into which the product to be treated is introduced continuously from above for a loading operation that is continuous or in batches. At least one of the two walls in contact with the product is heated and a hot gas is injected into the inner hollow cylinder, so as to make the heat consistent around the product contained within the first crown-shaped space defined by said first and second walls of the tank, between which the stirrer is integrated.
