The present invention relates to heat-treating equipment (1), in particular for roasting food products, including a tub (2) for receiving the product, which is associated with a stirring means (4) and a heat source (5), characterized in that the tub (2) consists of two vertical, coaxial and hollow cylinders (6, 7), the inner cylinder (6) defining a first wall (8), and the outer cylinder (7) defining a second wall (9) of a space (10) having a crown-shaped cross-section, into which the product (3) 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 (8, 9) in contact with the product (3) being heated (5) by conductivity via electric resistors or a heat transfer fluid, a hot gas (5) also being injected into the inner hollow cylinder (6), so as to make the heat consistent (5) around the product (3) contained within the first crown-shaped space (10) defined by said first and second walls (8, 9) of the tank (2), between which the stirring means (4) are integrated.
