Abstract

L'invention concerne une plaque d'évaporation destinée à la production de paillettes de glace au moyen d'un agent réfrigérant dans un processus de condensation et d'évaporation. La fonte des paillettes de glace depuis la surface de la plaque d'évaporation verticale (1) est générée par une arrivée de vapeur chaude par le biais de raccords (7) au niveau du bord inférieur de la plaque d'évaporation. La vapeur chaude est récupérée au niveau du bord supérieur. L'invention est caractérisée en ce que le bord inférieur de la plaque d'évaporation est évasé pour former un conduit tubulaire (2) et en ce que le dégagement de la vapeur chaude par ce conduit jusque dans la plaque d'évaporation se fait par des orifices (6) qui s'agrandissement à mesure que la distance aux raccords (7) augmente.
