Abstract

The plant is used for refrigeration, freezing or thawing of materials which are circulated continuously by mechanical transporter in a cold or warm air stream. The air is directed on the wall system vertically upward and deflected subsequently to flow vertically downwards on the material such as foodstuffs on a pallet. Air sweeps with uniform temp. in the whole plant over the travelling material. Air guiding baffle plates are arranged above the materials travelling path. These guide plates divide the air volume from fans into several air streams. Each of these streams is directed to a certain quantity of material. The air cooler is combined with a heating and water spraying system for thawing.

Description

Tunnelanlage zum kontinuierlichem KühlenTunnel system for continuous cooling

oder Gefrieren oder Auftauen von Gütern aller Art.or freezing or thawing of all kinds of goods.

Zum Kühlen oder Frieren von Lebensmitteln werden entweder Räume mit entsprechender Temperatur verwendet, in welche das Gut auf Hordenwagen oder Paletten eingeschoben werden. Das Gut bleibt solange im Raum, bis die gewünschte Endtemperatur erreicht ist. Dann wird es aus dem Raum herausgenommen und er kann wieder mit frischer Ware beschickt werden. Die Anlage arbeitet also periodisch. In Betrieben, wo kontinuierlich gearbeitet wird, verwendet man einen Tunnel, durch welchen das KUhl/Gefriergut auf Hordenwagen oder an einer Bahn hängend durchgezogen wird. Die Kühlluft wird im Gegenstrom zur Bewegung des Gutes geführt, wodurch sich die Temperaturdifferenz zwischen dem Gut und der Kühlraumluft dauernd ändert, denn das Gut wird kälter und die Luft wird wärmer und im ganzen Tunnel ist die Luftmenge konstant. Es sind auch Konstruktionen bekannt, wo mehrere Bahnen oder Hordenwagen nebeneinander durch den Tunnel transportiert werden, wobei die Luft dann auch durch Partien unterschiedlicher Temperatur geführt wird. Es trifft also stets die Luft aus dem Kühler zunächst auf die erste Transportstrecke, erwärmt sich hier und trifft dann auf die zweite, dritte usw.For cooling or freezing food, there are either rooms with corresponding temperature used in which the goods on trolleys or pallets be inserted. The goods remain in the room until the desired final temperature is reached. Then it is taken out of the room and he can use it again Goods are loaded. The system works periodically. In companies where continuously is worked, one uses a tunnel through which the refrigerated / frozen food Trolley or hanging on a track is pulled through. The cooling air is countercurrent led to the movement of the goods, whereby the temperature difference between the Good and the air in the refrigerator keeps changing, because the good gets colder and the air gets warmer and the air volume is constant throughout the tunnel. There are also constructions known where several lanes or trolleys are transported side by side through the tunnel The air is then also passed through sections of different temperatures will. The air from the cooler always hits the first transport route first, warms up here and then meets the second, third, etc.

Um die Verhältnisse zu bessern wurden die Kühlsysteme an der Decke angeordnet, mit vertikal nach unten blasenden Ventilatoren. Dadurch werden die Kühlverhältnisse wesentlich verbessert, das Verfahren ist jedoch mit verschiedenen Schwierigkeiten behaftet, die zu höheren Erstellungskosten der Anlage führen. Um dies zu vermeiden und optimale Kühl-/Gefrierverhältnisse zu schaffen wird erfindungsgemäß folgende Ausführung vorgeschlagen.To improve the situation, the cooling systems on the ceiling were installed arranged, with fans blowing vertically downwards. This will change the cooling conditions is substantially improved, but the process suffers from various difficulties afflicted, which lead to higher construction costs of the plant. To avoid this and to create optimal cooling / freezing conditions according to the invention is as follows Proposed execution.

Durch das isolierte Gehäuse (a) wird der Tunnel gebildet. Wie im allgemeinen Kühlraumbau üblich wird ein Luftkühler (b) an der Wand angeordnet und darüber, mit der Zirkulationswand (c) fluchtend der Ventilator (d). Im Tunnel sind Gleitschienen (e) montiert, an denen das Kühlgut (f) durch den Tunnel gezogen wird. In Höhe der Ventilatorachse wird ein Strömungsblech (g) eingebaut, das die Aufgabe hat den gesamten vom Ventilator geförderten Luftstrom in 2 Teile aufzulösen und so zu führen, daß jeweils ein Teilstrom über die beiden an der Gleitschiene (e) hängenden Kühlgütern allseits von dem nach unten gerichteten Luftstrom bestrichen werden. Die Zirkulationswand (c) wird bis in Bodennähe geführt, damit die Sicherheit besteht, daß das Kühlgut (f) in ganzer Länge vom Luftstrom erfaßt wird. Die Kältemittelleitungen (h) werden über (oder unter) dem Luftkühler verlegt. Unter dem Luftkühler (b) wird eine Tauwasserschale (e) in bekannter Art mit beheiztem Ablauf angeordnet.The tunnel is formed through the insulated housing (a). As in general Usually an air cooler (b) is placed on the wall and above it, with the circulation wall (c) is aligned with the fan (d). There are slide rails in the tunnel (e) mounted on which the refrigerated goods (f) are pulled through the tunnel. In the amount of The fan axis becomes a flow sheet (g) built in that the The task is to split the entire air flow conveyed by the fan into 2 parts and to lead in such a way that in each case a partial flow over the two on the slide rail (e) hanging refrigerated goods coated on all sides by the downward air flow will. The circulation wall (c) is brought close to the floor to ensure safety consists that the refrigerated goods (f) is covered over its entire length by the air stream. The refrigerant lines (h) are routed above (or below) the air cooler. Under the air cooler (b) will a condensate tray (s) arranged in a known manner with a heated drain.

Die Anlage ist auch zum Auftauen von gefrorenen Gütern im Warmluftstrom geeignet. Für diesen Verwendungszweck wird über dem Luftkühler (b) ein Heizregister (k) angeordnet und über diesem ein Rohr (1) mit Spritzdüsen, damit die am Heizregister (k) erwärmte Luft durch Einspritzen von Wasser befeuchtet werden kann.The system can also be used to thaw frozen goods in a stream of hot air suitable. A heating register is installed above the air cooler (b) for this purpose (k) and above this a pipe (1) with spray nozzles, so that the heating element (k) heated air can be humidified by injecting water.

Die Lufttemperatur wird durch einen Kühl- bzw. Heizthermostaten geregelt und die relative Feuchte beim Heizbetrieb durch einen Hygrostaten, der die Wassereinspeisung zu dem Düsensystem steuert. Durch die Kombination des Luftkühlers (b) mit dem Heizkörper (k) und der Befeuchtungsvorrichtung über das Düsensystem (1) kann der Raum auf einen in einem bestimmten Bereich wählbaren Luftzustand klimatisiert wgden. Der Tunnel kann in beliebiger Länge ausgeführt werden. Mit der Länge ändert sich die Zahl der in Reihe angeordneten Luftkühler und Ventilatoren. Es können auch beliebig viele derartige Einheiten (wie gezeichnet) nebeneinander angeordnet werden.The air temperature is regulated by a cooling or heating thermostat and the relative humidity during heating by means of a hygrostat that feeds water controls to the nozzle system. By combining the air cooler (b) with the radiator (k) and the humidifier via the nozzle system (1), the room can be on a wgden air-conditioned in a selectable air condition. The tunnel can be made in any length. The number of the changes with the length air coolers and fans arranged in series. Any number can also be used such units (as drawn) are arranged side by side.

Gegenüber der Montage der Luftkühler an der Decke hat die Wandanordnung folgende Vorteile: 1. Die Tunneldecke kann wesentlich leichter ausgeführt werden, da sie nicht mehr durch das Luftkühlergewicht belastet wird.Compared to the installation of the air cooler on the ceiling, the wall arrangement has the following advantages: 1. The tunnel ceiling can be made much lighter, because it is no longer burdened by the weight of the air cooler.

2. Wandluftkühler sind wesentlich billiger als Decken-Luftkühler.2. Wall air coolers are much cheaper than ceiling air coolers.

3. Bei Deckenluftkühlern müssen isolierte, beheizte Schmelz-3. In the case of ceiling air coolers, insulated, heated melting
