A cryogenic processor (10) is provided for liquid feed preparation of a free- flowing frozen product. The cryogenic processor (10) includes a freezing chamber (12) having a substantially conical shape, at least one feed tray (48) overlying the freezing chamber (12) arranged and adapted to receive liquid composition from a delivery source (50), the tray (48) having a plurality of orifices (44) for discharge of uniformly sized droplets of the composition from the feed tray (48), whereby the droplets are delivered by gravity into the freezing chamber (12) therebelow. The cryogenic processor (10) also includes at least one sensor (66) associated with the feed tray (48) for determining a depth of liquid composition in the feed tray (48), at least one valve associated with a liquid composition delivery line (52), the valve being configured to control the rate at which liquid composition is delivered from the delivery source (50) to the feed tray (48) and a controller responsive (68) to the at least one sensor for controlling a position of the valve, and therefore the rate at which liquid composition is delivered from the delivery source (50) to the feed tray (48).
Cette invention concerne un dispositif de traitement cryogène (10) assurant la préparation de l'alimentation liquide destinée à un produit congelé à écoulement fluide. Le dispositif de traitement cryogène (10) comprend une chambre de congélation (12) de forme sensiblement conique, au moins un plateau d'alimentation (48) disposé au-dessus de la chambre de congélation (12) et conçu pour recevoir une composition liquide provenant d'une source d'alimentation (50), le plateau (48) présentant une pluralité d'orifices (44) que traversent des gouttelettes de taille uniforme de la composition présente sur le plateau (48) avant de tomber dans la chambre de congélation (12) située au-dessous. Le dispositif de traitement cryogène (10) comprend également au moins un capteur (66) associé au plateau d'alimentation (48), qui détermine la profondeur de la composition liquide dans ledit plateau (48), au moins une soupape associée à la canalisation d'alimentation en composition liquide (52), soupape conçue pour régler le débit d'amenée de la composition liquide depuis la source (50) jusqu'au plateau (48), et une unité de commande qui réagit (68) au détecteur de position de la soupape, et donc au débit d'amenée de la composition liquide depuis la source (50) jusqu'au plateau (48).
