Description

14 zum Anschluß an die Saugdüse 9 bestimmt. Auf der Oberseite weist der Karton 11 einen abnehmbaren Deckel 15 auf.14 intended for connection to the suction nozzle 9. On the top, the carton 11 has a removable one Cover 15 open.

Die vertikale Wand S ist im Bereich jedes Kartons 11 mit aus Gummi hergestellten Dichtungen 16 versehen, um die Leckage von Luft außerhalb des auf der Konsole IC angebrachten Kartons der vertikalen Wand entlang zu bzw. von der Düse 8,9 zu verhindern. The vertical wall S is provided in the area of each cardboard box 11 with seals 16 made of rubber, around the leakage of air outside the cardboard of the vertical mounted on the console IC Wall along to or from the nozzle 8.9 to prevent.

Wenn kein Karton 11 auf der Konsole 10 angebracht ist, ist diese hochgeklappt, um die Düsen 8,9 abzudecken, wodurch ein Ausströmen von Kühlluft in den die Anlage umgebenden Raum verhütet wird. Um eine wirksame Abdichtung der Düse zu bewirken, liegt die Konsole in der hochgeklappten Lage gegen die Dichtungen 16 an.If no cardboard box 11 is attached to the console 10, this is folded up to the nozzles 8,9 to cover, whereby a leakage of cooling air into the room surrounding the system is prevented. Around To effect an effective sealing of the nozzle, the console lies against in the folded-up position the seals 16 on.

Damit die Kühlluft auf ihrem Wege von der Speisedüse 8 zur Saugdüse 9 unbehindert durch den Karton 11 strömen kann, sind Distanzglie Jer 17 zwischen den Innenwänden des Kartons und den gefrorenen Waren 12 angeordnet, mit Ausnahme von der Innenwand, die sich zwischen den Düsen 8 und 9 befindet. Hierdurch wird die Kühlluft gezwungen, um die Waren herumzuströmen und diese zu kühlen.So that the cooling air on its way from the feed nozzle 8 to the suction nozzle 9 unhindered through the box 11 can flow, spacers are Jer 17 between the inner walls of the cardboard box and the frozen Goods 12 arranged, with the exception of the inner wall, which is located between the nozzles 8 and 9. This forces the cooling air to flow around the goods and cool them.

Die oben beschriebene und in der Zeichnung dargestellte Gefrieranlage arbeitet in folgender Weise:The freezer system described above and shown in the drawing works in the following way:

Wenn die Kartons 11 auf den Konsolen 10 angebracht sind und die Öffnungen 13, 14 an die Düsen angeschlossen sind, strömt Kühlluft vom Kälteaggregat 3 durch den Kanal 6 und unter Vermittlung der Speisedüse 8 in den Karton. Im Karton strömt die Kühlluft um die Waren herum, um diese zu kühlen. Danach wird die Kühlluft von der Saugdüse 9 aus dem Karton herausgesaugt und in den Kanal 7 zum Kälteaggregat 3 befördert, um aufs neue gekühlt zu werden.When the cardboard boxes 11 are attached to the consoles 10 and the openings 13, 14 to the nozzles are connected, cooling air flows from the refrigeration unit 3 through the channel 6 and mediated by the Feed nozzle 8 in the box. In the box, the cooling air flows around the goods to cool them. Then the cooling air is sucked out of the box by the suction nozzle 9 and into the channel 7 to the refrigeration unit 3 promoted to be cooled again.

Dieser Kreislauf der Kühlluft spielt sich kontinuierlich ab. Wenn sämtliche Waren aus einem Karton herausgeholt worden sind, wird der Karton von der Konsole 10 abgenommen, wonach entweder ein neuer Karton angebracht oder die Konsole in Anlage gegenThis cycle of cooling air takes place continuously.
