Abstract
L'invention concerne un procédé pour traiter par la chaleur des produits non enveloppes, au moyen d'un fluide ayant une température différente de celle du produit et qui est amené à fournir de la chaleur à ceux-ci ou à leur en enlever. Selon l'invention, on place les produits sur un support imperméable présentant la forme d'une bande transporteuse ou analogue, ayant une conductivité thermique élevée, puis on couvre les produits avec une couche de couverture mince, étanche aux fluides et flexible, qui peut se déplacer parallèlement à la bande transporteuse et qui a une largeur supérieure à celle des produits reposant sur le support, après quoi on projette contre la face inferieure du support un fluide ayant une température différente de celle des produits, en arrosant en même temps sous pression la face supérieure de la couche de couverture avec un tel fluide. Application au traitement des produits alimentaires.The invention relates to a process for heat treating non-enveloped products, using a fluid having a temperature different from that of the product and which is caused to supply or remove heat from them. According to the invention, the products are placed on an impermeable support in the form of a conveyor belt or the like, having a high thermal conductivity, and then the products are covered with a thin, fluid-tight and flexible covering layer, which can move parallel to the conveyor belt and which has a width greater than that of the products resting on the support, after which a fluid having a temperature different from that of the products is sprayed against the lower face of the support, while spraying at the same time under pressure the upper face of the cover layer with such a fluid. Application to the treatment of food products.
