Abstract

An apparatus for treatment of products with gas comprises a housing (1), a fan (4) for circulating treating gas in the housing, and a conveyor belt (2) having a foraminous product-carrying base (11) for moving the products through the housing, said conveyor belt following, along part of its length, a helical path in the housing. A duct (10) of subtantially rectangular cross section and of the same helical shape as the helical path of the conveyor belt (2) accommodates the conveyor belt in the helical path thereof, with the product-carrying base (11) positioned between the bottom and top of the duct. The bottom and top of the duct are closed, and the duct has a closure on its one side above and, on its other side, below the product-carrying base. Otherwise, the sides of the duct are gas-permeable. Means (6-8) are arranged for guiding the gas flow in the radial direction relative to a hollow cylinder formed of the duct, such that the gas flow passes through this via the foraminous product-carrying base of the conveyor belt in series with the gas-permeable parts of the sides of the duct adjacent to the product-carrying surface.
