Title (EN) METHOD AND APPARATUS FOR SURFACE FREEZING
(FR) PROCEDE ET APPAREIL DE CONGELATION SUPERFICIELLE
Abstract:
(EN) In a method of freezing a surface layer of a food product (6), this is placed on a non-foraminous conveyor belt (7). Cold air in the form of jets is blown towards the underside of the non-foraminous conveyor belt. An apparatus for carrying out the method comprises, in addition to the non-foraminous conveyor belt (7), a plurality of stationary nozzles (14) for producing jets towards the underside of the non-foraminous conveyor belt in an area which extends over the width of the non-foraminous conveyor belt.
(FR) L'invention concerne un procédé de congélation d'une couche superficielle d'une denrée alimentaire (6). Selon ce procédé, la denrée alimentaire est placée sur une courroie transporteuse (7) non-foraminée. De l'air froid est soufflé sous forme de jets sur la face inférieure de la courroie transporteuse non-foraminée. L'appareil permettant d'appliquer ce procédé comprend non seulement la courroie transporteuse (7) non-foraminée mais aussi plusieurs buses stationnaires (14) servant à produire des jets en direction de la face inférieure de la courroie transporteuse non-foraminée dans une zone qui s'étend sur toute la largeur de la courroie transporteuse non-foraminée.
