Title
(EN) APPARATUS FOR GAS TREATMENT OF PRODUCTS
(FR) APPAREIL DE TRAITEMENT GAZEUX DE PRODUITS
Abstract
(EN)
An apparatus for gas treatment of products comprises a housing having top, bottom and side walls; a conveyor belt for transporting the products along a first path in the housing; a tunnel having perforated walls and enclosing the conveyor belt along the first path; gas circulation means communicating with the tunnel via the perforated walls for circulating gas into the tunnel in the form of gas jets impinging upon the products carried by the conveyor belt, and out of the tunnel in a return channel back to the gas circulation means; and gas conditioning means positioned in the return channel for conditioning the gas circulated by the gas circulation means. Walls connecting with the perforated walls of the tunnel and having an opening towards the gas circulation means form a high-pressure chamber substantially above the tunnel and spaced from the walls of the housing. At least one substantially vertical part of the connecting walls of the high-pressure chamber is removable so as to provide access to the inside of the pressure chamber. Further, at least one of the side walls of the housing along the high-pressure chamber may be movable so as to widen the space between said at least one wall and the high-pressure chamber.
(FR)
L'invention porte sur un appareil de traitement gazeux de produits qui comprend un corps constitué de parois supérieure, inférieure et latérales ; un courroie transporteuse acheminant les produits le long d'une première voie dans le corps ; un tunnel doté de parois perforées et abritant la courroie transporteuse le long de la première voie ; un organe de circulation du gaz communiquant avec le tunnel via les parois perforées en vue de faire circuler un gaz à l'intérieur du tunnel sous forme de jets heurtant les produits transportés par la courroie transporteuse, et à l'extérieur du tunnel dans un canal de retour vers l'organe de circulation du gaz ; et un organe de conditionnement du gaz placé dans le canal de retour pour conditionner le gaz envoyé par l'organe de circulation. Des parois se raccordant aux parois perforées du tunnel et possédant une ouverture orientée vers l'organe de circulation du gaz forment une chambre haute pression pratiquement au-dessus du tunnel et espacée des parois du corps. Au moins une partie pratiquement verticale des parois de raccordement de la chambre haute pression est amovible de façon à avoir accès à l'intérieur de la chambre haute pression. De plus, au moins une des parois latérales du corps, le long de la chambre haute pression, peut être déplacée de manière à agrandir l'espace entre au moins cette paroi et la chambre haute pression.
