Abstract
A tunnel for cooling, heating, or drying products of the foodstuffs and especially confectionery industries. The tunnel has a base, especially one comprising several adjacent segments (4), a series of self-supporting hoods (5) that have a cross-section in the form of an inverted U and are made of rigid expanded plastic, tracks (9) between the edges of the base (2) and the walls (7) of the hoods to create a seal, and a belt (21) to convey the products (22) longitudinally through the interior (10) of the tunnel. Take-apart hinges (13 or 26) are positioned between the edges of the base and the walls of the hoods on each side of the tunnel.
