ABSTRACT:
The apparatus comprises a steel belt (5) extending according to an endless strap around two guide rollers (3, 4) driven in rotation according to horizontal axes. The upper part of the belt (5) defines a first going stretch (5a) onto which the product (6) in progress of working is laid, said product being transported due to the movement communicated to the belt as a result of the rotation of said guide rollers. Water is sprayed against the underneath surface of the first belt stretch for cooling the product through a heat exchange with the belt itself. The apparatus further comprises a heat exchange roller (14) rotatably supported according to the horizontal axis and arranged so that it comes in contact with the product (6) located on the first belt stretch (5a). Water circulation takes place within the heat exchange roller (14) and an additional cooling action is therefore accomplished on said product (6).
