Abstract

Dans cette installation, les éléments constituant la bande transporteuse circulent à l'intérieur d'un carter thermiquement isolé dont le volume intérieur est chauffé; dans un mode de réalisation, des moyens sont prévus pour assurer une circulation d'air chaud en circuit fermé dans les différentes parties du carter de l'installation. Des clapets, commandés par exemple par des capteurs de température, permettent de régler cette circulation. Un ventilateur envoie de l'air de refroidissement lorsqu'une température limite prédéterminée est dépassée.In this installation, the elements constituting the conveyor belt circulate inside a thermally insulated casing, the interior volume of which is heated; in one embodiment, means are provided to ensure a circulation of hot air in a closed circuit in the different parts of the casing of the installation. Valves, controlled for example by temperature sensors, make it possible to regulate this circulation. A fan sends cooling air when a predetermined temperature limit is exceeded.
