Abstract

La présente invention concerne un dispositif de refroidissement (1) destiné à des blocs de gaufrettes (2), comprenant un dispositif d'acheminement principal (8) qui achemine des conteneurs de transport (6) contenant des cloisons intermédiaires superposées, d'une zone d'entrée (3) dans laquelle les contenants de transport (6) sont garnis de blocs de gaufrettes (2), via une zone de refroidissement (4) dans laquelle les blocs de gaufrettes (2) reposant sur les cloisons intermédiaires des contenants de transport (6), sont refroidis, jusqu'à une zone de sortie depuis laquelle les blocs de gaufrettes refroidis sont prélevés des contenants de transport (6) et extraits du dispositif de refroidissement (1). Un dispositif d'acheminement de retour (9) qui circule dans le sens opposé à celui du dispositif d'acheminement principal (8), renvoie les contenants de transport vides (6') vers la zone d'entrée (3). Le dispositif de refroidissement peut être équipé de contenants de transport empilables qui, après remplissage avec des blocs de gaufrettes, sont acheminés à travers la zone de refroidissement sous la forme de piles de contenants. Le dispositif de refroidissement peut présenter une zone tampon qui est disposée en amont de la zone de refroidissement et peut être remplie temporairement de contenants de transport garnis de blocs de gaufrettes.
