Title (EN) METHOD AND DEVICE FOR APPLYING A MATERIAL TO A MOVING BELT
(FR) PROCÉDÉ ET DISPOSITIF D'APPLICATION D'UNE MATIÈRE SUR UNE BANDE EN MOUVEMENT
(DE) VERFAHREN UND VORRICHTUNG ZUR AUFBRINGUNG EINES STOFFS AUF EINE SICH BEWEGENDE BAHN
Abstract:
(EN) In a method for applying a material to a moving belt (4) transporting a product, an air-vapour mixture is supplied to at least one nozzle (13) via which the material is applied to the belt (4) in an application zone (32), by means of the air-vapour mixture as a blowing agent. Excess air-vapour mixture and excess material are removed from the application zone (32). The aim of the invention is to improve the energy efficiency of such a method. To this end, at least part of the excess air-vapour mixture removed from the application zone (32) is recycled and supplied back to the nozzle (13). The invention further relates to a device (1) for carrying out the above-mentioned method.
(FR) Dans un procédé d'application d'une matière sur une bande en mouvement (4) d'un produit, un mélange vapeur-air est amené à au moins une buse (13) dans laquelle la matière est appliquée sur la bande (4) dans une zone d'application (32) au moyen du mélange air-vapeur utilisé comme propulseur. Le mélange air-vapeur en excès et la matière en excès sont éliminés de la zone d'application (32). Pour améliorer le rendement énergétique d'un tel procédé, il est proposé de recycler au moins une partie du mélange air-vapeur en excès évacué de la zone d'application (32) et de la ramener à l'au moins une buse (13). En outre, l'invention concerne un dispositif (1) destiné à mettre en œuvre le procédé décrit ci-dessus.
(DE) Bei einem Verfahren zur Aufbringung eines Stoffs auf eine sich bewegende Bahn (4) eines Guts wird ein Luft-Dampf-Gemisch mindestens einer Düse (13) zugeführt, in der der Stoff mittels des Luft-Dampf-Gemischs als Treibmittel in einer Aufbringungszone (32) auf die Bahn (4) aufgebracht wird. Überschüssiges Luft-Dampf-Gemisch und überschüssiger Stoff werden aus der Aufbringungszone (32) abgeführt. Um die Energieeffizienz eines derartigen Verfahrens zu verbessern, wird vorgeschlagen, dass zumindest ein Teil des aus der Aufbringungszone (32) abgeführten, überschüssigen Luft-Dampf-Gemischs recycelt und der mindestens einen Düse (13) wieder zugeführt wird. Darüber hinaus wird eine Vorrichtung (1) zur Durchführung des vorstehend beschriebenen Verfahrens vorgeschlagen.
