Abstract

L'invention concerne un procédé continu pour la surgélation individuelle de produits (P) tels que notamment des légumes, dans lequel :
- on forme une couche de produits, en mouvement continu,
- on soumet la couche de produits à une étape de surgélation de type à lit fluidisé au cours de laquelle la couche de produits est mise en suspension dynamique sous la portance d'un flux d'air frigoporteur (23) de vitesse V1, afin d'obtenir une congélation des produits à leur périphérie, puis,
- on soumet la couche de produits à une étape de surgélation du type à lit fixe au cours de laquelle la couche de produits est plaquée contre un support sous l'effort d'un flux d'air frigoporteur de vitesse V2, supérieure à V1, afin d'obtenir la congélation totale à coeur des produits.The invention relates to a continuous process for the individual quick freezing of products (P) such as in particular vegetables, in which:
a layer of products is formed, in continuous movement,
the product layer is subjected to a fluidised-bed type freezing step during which the product layer is dynamically suspended under the load of a refrigerant air flow (23) of velocity V1, in order to get a freezing of the products at their periphery, then,
the product layer is subjected to a fixed-bed type deep-freezing step during which the product layer is pressed against a support under the force of a refrigerant air flow velocity V2 greater than V1, in order to achieve total freezing at the heart of the products.

L'invention concernera également un dispositif pour la mise en oeuvre du procédé.
