Description

Die Erfindung betrifft eine Vorrichtung zum Herstellen, Portionieren, Abfüllen und Lagern von klaren Kleineiskörpern gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for producing, portioning, filling and storing clear small ice bodies according to the preamble of claim 1.

Vorrichtungen zur Herstellung von klaren Kleineiskörpern durch Gefrieren von Wasser sind in den unterschiedlichsten Konstruktionen bekannt. Handelsübliche Maschinen können bis zu 1.000 kg Kleineiskörper pro Tag erzeugen.Devices for the production of clear small ice bodies by freezing water are known in a wide variety of designs. Commercial machines can produce up to 1,000 kg of small ice cream bodies per day.

Um die Kleineiskörper sowohl hygienisch als auch rationell handhaben zu können, wurden sogenannte Dispenser entwickelt, in denen die Kleineiskörper gelagert und auf Anforderung hin in kontrollierbaren Mengen abgegeben werden. Es handelt sich dabei im wesentlichen um ein isoliertes Gehäuse, in das die fertigen Kleineiskörper von oben hineingeworfen werden, in dem sie mit Hilfe einer Einrichtung, oft in Form einer Rohrschnecke, umgewälzt werden, um ein Zusammenfrieren zu verhindern, und aus dem sie über beispielsweise eine bodenseitige Auslaßöffnung ausgegeben werden. Derartige Vorrichtungen sind bekannt aus der DE-OS 24 54 348 oder den US-PSen 4 084 725 und 4 512 502.So-called dispensers have been developed in order to be able to handle the small ice cream bodies both hygienically and rationally, in which the small ice cream bodies are stored and released in controllable quantities on request. It is essentially an insulated housing into which the finished small ice cream bodies are thrown from above, in which they are circulated with the aid of a device, often in the form of a tubular screw, in order to prevent freezing up, and from which they are, for example a bottom outlet opening are issued. Such devices are known from DE-OS 24 54 348 or US Pat. Nos. 4,084,725 and 4,512,502.

Eine solche Vorrichtung ist aber auch handelsüblich. Es handelt sich dabei im wesentlichen um einen wärmeisolierten, zylindrischen Fiberglas-Silo, auf dessen Deckel ein oder zwei Kleineiskörperbereiter positioniert werden können. Im Zentrum des Silobodens ist eine Auslaßöffnung vorgesehen, unter der eine Förderschnecke beginnt. Im Silo ist eine um dessen Mittelachse umlaufende rotierende Schnecke vorgesehen, die den Vorrat an Kleineiskörpern auflockert und zur Auslaßöffnung fördert.Such a device is also commercially available. It is essentially a heat-insulated, cylindrical fiberglass silo, on the lid of which one or two small ice cream makers can be positioned. An outlet opening is provided in the center of the silo floor, under which a screw conveyor begins. In the silo there is a rotating screw that rotates around its central axis, which loosens up the supply of small ice bodies and conveys it to the outlet opening.

In Supermärkten, Flughäfen, Fisch verarbeitenden Betrieben, Catering-Gesellschaften usw. werden die Kleineiskörper in großen Mengen zentral erzeugt und in Plastikbeuteln verpackt zu den Verbrauchsstellen transportiert. Um ein Schmelzen der Kleineiskörper in den Beuteln zu verhindern, werden diese in separaten Gefrierräumen bei Temperaturen unterhalb des Gefrierpunktes aufbewahrt. Der Transport an die Verbrauchsstellen erfolgt in Fahrzeugen oder Behältern mit Eigenkühlung, wo gegebenenfalls wiederum eine Zwischenlagerung in besonderen Gefrierräumen und -behältern erfolgt.In supermarkets, airports, fish processing companies, catering companies, etc., the small ice cream bodies are produced centrally in large quantities and transported in plastic bags to the consumption points. To prevent the small ice cream bodies in the bags from melting, they are stored in separate freezer rooms at temperatures below freezing. The transport to the consumption points takes place in vehicles or containers with self-cooling, where, if necessary, intermediate storage takes place in special freezer rooms and containers.

Es versteht sich, daß die Bereitstellung von Gefrierräumen und -behältern für die mehrfache Zwischenlagerung der mit Kleineiskörpern gefüllten Beutel sowie der Transport der zentral mit Kleineiskörpern befüllten Beutel in mit Eigenkühlung versehenen Transporteinrichtungen zu den Verbrauchsstellen einen erheblichen Aufwand verursacht. Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine in den unterschiedlichsten Größen herstellbare,kompakte Vorrichtung der gattungsgemäßen Art anzugeben, die eine Gefriereinrichtung zum kontinuierlichen Erzeugen der Kleineiskörper aus Wasser, ein isoliertes Gehäuse zum Zwischenlagern der Kleineiskörper mit den erforderlichen Einrichtungen zum Umwälzen der Kleineiskörper und zum Fördern derselben zu einer bodenseitigen Auslaßöffnung, eine Einrichtung zum Portionieren und Abfüllen der Kleineiskörper in Beutel und ein isoliertes Gehäuse zum Lagern der gefüllten Beutel umfaßt.It goes without saying that the provision of freezer rooms and containers for the multiple interim storage of the bags filled with small ice bodies and the transport of the bags filled centrally with small ice bodies in transport devices provided with self-cooling to the consumption points causes considerable expenditure. The present invention is therefore based on the object of specifying a compact device of the generic type which can be produced in a wide variety of sizes and which has a freezer for continuously producing the small ice cream bodies from water, an insulated housing for intermediate storage of the small ice cream bodies with the necessary devices for circulating the small ice cream bodies and for conveying the same to a bottom outlet opening, a device for portioning and filling the small ice cream bodies into bags and an insulated housing for storing the filled bags.

Diese Aufgabe wird gelöst durch eine gattungsgemäße Vorrichtung mit den Merkmalen gemäß Kennzeichen des Anspruchs 1.This object is achieved by a generic device with the features according to the characterizing part of claim 1.

Der wesentliche Vorteil der erfindungsgemäßen Vorrichtung ist darin zu sehen, daß sie direkt am Verbrauchsort aufgestellt werden kann. Dadurch entfallen die gesonderten Gefrierräume bzw. -behälter und die mit einer Eigenkühlung ausgerüsteten Transportvorrichtungen. Dank der kompakten Bauart können die Kälteverluste und damit der Energieverbrauch gering gehalten werden, ohne daß Bedienung und Handhabung der Vorrichtung darunter leiden.The main advantage of the device according to the invention can be seen in the fact that it can be installed directly at the point of use. This eliminates the separate freezer rooms or containers and the transport devices equipped with self-cooling. Thanks to the compact design, the cold losses and thus the energy consumption can be kept low without the operation and handling of the device suffering.

Um die Arbeit des Bedienungspersonals beim Portionieren und Abfüllen der Kleineiskörper insbesondere bei Großanlagen zu erleichtern, ist unter ihr vorzugsweise eine Arbeitsplatte positioniert, die vorteilhafterweise mit einer Ableitung für Tauwasser ausgerüstet ist.In order to facilitate the work of the operating personnel when portioning and filling the small ice cream bodies, especially in large systems, a worktop is preferably positioned below it, which is advantageously equipped with a drain for condensation water.

Die im Zwischenlagergehäuse zum Auflockern und Transportieren der Kleineiskörper verwendete Rohrschnecke rotiert vorzugsweise waagerecht, ist oberhalb der Auslaßöffnung positioniert und mit Rechts- und/oder Linkssteigung gewendelt. Dadurch können die Kleineiskörper ohne Änderung der Drehrichtung der Schnecke von allen Seiten der beliebig positionierbaren Auslaßöffnung zugefördert werden.The tubular screw used in the intermediate storage housing for loosening and transporting the small ice cream body preferably rotates horizontally, is positioned above the outlet opening and is coiled with a right and / or left slope. As a result, the small ice cream bodies can be conveyed from all sides of the freely positionable outlet opening without changing the direction of rotation of the screw.

Um insbesondere in großen Zwischenlagergehäusen und bei längeren Zwischenlagerzeiten ein Zusammenfrieren der Kleineiskörper zuverlässig zu verhindern, können zusätzliche rotierende Drehkreuze vorgesehen werden.In order to reliably prevent the small ice bodies from freezing together, particularly in large intermediate storage housings and in the case of longer intermediate storage times, additional rotating turnstiles can be provided.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist die Bodenplatte im Zwischenlagergehäuse an Federn beweglich aufgehängt. In Abhängigkeit vom Gewicht der Kleineiskörper hebt und senkt sich die Bodenplatte und kann so vorgesehene Endschalter betätigen, die die Gefriereinrichtung ein- und ausschalten entsprechend der Entnahme der Kleineiskörper aus dem Zwischenlagergehäuse.According to a preferred embodiment of the invention, the base plate is movably suspended on springs in the intermediate storage housing. Depending on the weight of the small ice cream bodies, the base plate rises and lowers and can thus operate the limit switches provided, which switch the freezer on and off in accordance with the removal of the small ice cream bodies from the intermediate storage housing.

Vorteilhafterweise ist die Einwurföffnung im Lagergehäuse mit einem Streifenvorhang verschlossen, die Entnahmeöffnung mit einer Schwenkklappe. Beides dient dem Ziel, das Innere des Lagergehäuses leicht zugänglich zu halten, ohne daß unerwünscht große Kälteverluste auftreten.The insertion opening in the bearing housing is advantageously closed with a strip curtain and the removal opening with a swivel flap. Both serve the goal of keeping the inside of the bearing housing easily accessible without undesirably large cold losses.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist im Lagergehäuse eine Rutschplatte an Federn beweglich aufgehängt und von der Einwurföffnung zur Entnahmeöffnung hin geneigt. Dabei sind die Federn der Rutschplatte vorteilhafterweise so dimensioniert, daß die Rutschplatte sich bei vollem Lagergehäuse bis auf den Gehäuseboden absenkt. Durch diese Konstruktion wird erreicht, daß auch in einem quaderförmigen Lagergehäuse die gefüllten Beutel sich im Bereich der Entnahmeöffnung sammeln, ohne daß die Lagerkapazität leidet, wie es beim Einbau einer festen Rutschplatte der Fall wäre.According to a preferred embodiment of the invention, a slide plate is movably suspended from springs in the bearing housing and is inclined from the insertion opening to the removal opening. The springs of the slide plate are advantageously dimensioned such that the slide plate lowers to the bottom of the housing when the bearing housing is full. With this construction it is achieved that even in a cuboid bearing housing, the filled bags collect in the area of the removal opening without the storage capacity suffering, as would be the case when installing a fixed slide plate.

Die Einrichtung zum Erzeugen des Kaltluftschleiers vor der Entnahmeöffnung und/oder der Einwurföffnung besteht vorzugsweise aus einer Kältemaschine und einem Verdampfer, gegebenenfalls mit einem Ventilator. Diese Einrichtung hält auch die Lagertemperatur unterhalb des Gefrierpunktes, so daß die Kleineiskörper in den Beuteln nicht tauen.The device for generating the cold air curtain in front of the removal opening and / or the insertion opening preferably consists of a refrigerator and an evaporator, optionally with a fan. This device also keeps the storage temperature below freezing, so that the small ice cream bodies do not thaw in the bags.

Ein besonderes Augenmerk der Erfindung gilt auch der Portionier- und Abfüllvorrichtung. Deren Füllkammer besitzt vorzugsweise boden- und deckenseitig Scherenverschlüsse, die abwechselnd geöffnet und geschlossen werden.The portioning and filling device also pays particular attention to the invention. Their filling chamber preferably has scissor closures on the floor and ceiling, which are alternately opened and closed.

Vorteilhafterweise sind die boden- und deckenseitigen Verschlüsse der Füllkammer pneumatisch oder auch elektromagnetisch betätigbar.The closures of the filling chamber on the floor and ceiling are advantageously pneumatically or electromagnetically operable.

Die Füllkammer selbst befindet sich vorzugsweise direkt unterhalb der Auslaßöffnung im Zwischenlagergehäuse, so daß die Kleineiskörper dank der Schwerkraft in die Füllkammer fallen können. Außerdem ist auf diese Weise die Menge der portionierten Kleineiskörper immer gleich, unabhängig von der tatsächlichen Größe der Kleineiskörper.The filling chamber itself is preferably located directly below the outlet opening in the intermediate storage housing, so that the small ice cream bodies can fall into the filling chamber thanks to gravity. In addition, the amount of portioned ice cream is always the same, regardless of the actual size of the ice cream.

Um das Abpacken der Kleineiskörper in den Beuteln zu erleichtern, ist die Portionier- und Abfülleinrichtung mit einem Halter für die Beutel ausgerüstet.To make it easier to pack the small ice cream bodies in the bags, the portioning and filling device is equipped with a holder for the bags.

Zum Verschließen der Beutel ist auch eine Beutelverschließeinrichtung, vorzugsweise eine Schweißeinrichtung für Kunststoffolien, vorgesehen.A bag closing device, preferably a welding device for plastic films, is also provided for closing the bags.

Anhand der Zeichnung soll die Erfindung in Form eines Ausführungsbeispiels näher erläutert werden.Based on the drawing, the invention will be explained in more detail in the form of an embodiment.

Man erkennt in schematischer Darstellung einen Querschnitt durch eine Vorrichtung zum Herstellen, Portionieren, Abfüllen und Lagern von klaren Kleineiskörpern. Diese besitzt im dargestellten Beispiel zwei übereinander montierte Gefriereinrichtungen 10 herkömmlicher Bauart, umfassend z. B. einen Verdampfer mit Gefrierzellen, eine Wasserwanne und eine Wassersprüheinrichtung. Kältemaschinen 11 erzeugen die erforderliche Gefrierleistung. Zahl und Größe der Gefriereinrichtungen 10 können problemlos an den jeweiligen Bedarf angepaßt werden.A cross-section through a device for producing, portioning, filling and storing clear ice cream bodies can be seen in a schematic representation. In the example shown, this has two freezers 10 of conventional construction mounted one above the other, comprising e.g. B. an evaporator with freezer cells, a water pan and a water spray device. Chillers 11 produce the required freezing capacity. The number and size of the freezers 10 can be easily adapted to the respective needs.

Die in den Gefriereinrichtungen 10 erzeugten Kleineiskörper 1 fallen direkt in ein isoliertes Zwischenlagergehäuse 20. In diesem erkennt man zunächst eine an Federn 22 beweglich aufgehängte und zu einer bodenseitigen Auslaßöffnung 27 hin geneigte Bodenplatte 21. Die Bodenplatte 21 betätigt in Abhängigkeit vom Gewicht der auf ihr liegenden Kleineiskörper 1 Endschalter 23, über die die Gefriereinrichtungen 10 ein- und ausgeschaltet werden können.The small ice cream bodies 1 produced in the freezing devices 10 fall directly into an insulated intermediate storage housing 20. In this one first recognizes a base plate 21 which is movably suspended on springs 22 and inclined towards a base-side outlet opening 27. The base plate 21 actuates depending on the weight of the components lying on it Small ice cream body 1 limit switch 23, via which the freezing devices 10 can be switched on and off.

Oberhalb der bodenseitigen Auslaßöffnung 27 rotiert eine an einer Welle 24 befestigte Rohrschnecke 25. Diese ist in Abhängigkeit von der Position der Auslaßöffnung 27 mit Rechts- und/oder Linkssteigung gewendelt, so daß die Kleineiskörper von allen Seiten des Zwischenlagergehäuses 20 zu der beliebig positionierbaren Auslaßöffnung 27 gefördert werden, bei immer gleicher Drehrichtung der Schnecke 25.Above the outlet opening 27 on the bottom, a tubular worm 25 fastened to a shaft 24 rotates. Depending on the position of the outlet opening 27, it is coiled with a right and / or left slope, so that the small ice cream bodies from all sides of the intermediate bearing housing 20 to the outlet opening 27 which can be positioned as desired are promoted, with the screw 25 always rotating in the same direction.

Rotierende Drehkreuze 26 sorgen dafür, daß auch in großen Zwischenlagergehäusen 20 und bei längeren Zwischenlagerzeiten ein Zusammenfrieren der Kleineiskörper 1 sicher verhindert wird.Rotating turnstiles 26 ensure that the small ice bodies 1 are reliably prevented from freezing together even in large intermediate storage housings 20 and in the case of longer intermediate storage times.

Direkt unterhalb der Auslaßöffnung 27 im Zwischenlagergehäuse 20 ist eine Portionier- und Abfüllvorrichtung 40 montiert. Diese besteht aus einer Füllkammer 41 mit einem deckenseitigen und einem bodenseitigen Verschluß 42, 43. Diese Verschlüsse 42, 43 werden von einem Pneumatikzylinder 44 oder auch einem Elektromagneten abwechselnd geöffnet und geschlossen. Besonders eignen sich sogenannte Scherenverschlüsse, deren Funktion von den relativ groben Kleineiskörpern 1 nicht behindert wird.A portioning and filling device 40 is mounted directly below the outlet opening 27 in the intermediate storage housing 20. This consists of a filling chamber 41 with a top-side and a bottom-side closure 42, 43. These closures 42, 43 are alternately opened and closed by a pneumatic cylinder 44 or an electromagnet. So-called scissor closures are particularly suitable, the function of which is not hindered by the relatively coarse small ice bodies 1.

Die in der Füllkammer 41 portionierten Kleineiskörper 1 fallen nach Schließen des deckenseitigen Verschlusses 42 und anschließendem Öffnen des bodenseitigen Verschlusses 43 in einen Beutel 2. Dieser steht auf einer Arbeitsplatte 45, deren Oberseite perforiert und mit einer Ableitung für Tauwasser versehen ist.The small ice cream bodies 1 portioned in the filling chamber 41 fall into a bag 2 after closing the top-side closure 42 and then opening the bottom-side closure 43. The latter rests on a worktop 45, the upper side of which is perforated and provided with a condensate drain.

Zum Verschließen der Beutel 2 dient eine der handelsüblichen Beutelverschließvorrichtungen, gegebenenfalls eine Schweißeinrichtung für Kunststoffolien.One of the commercially available bag closing devices, possibly a welding device for plastic films, is used to close the bags 2.

Unmittelbar benachbart zur Portionier- und Abfülleinrichtung 40 erkennt man eine Einwurföffnung 33, die mit einem Streifenvorhang verschlossen ist und durch die die mit Kleineiskörpern 1 gefüllten und verschlossenen Beutel 3 in ein isoliertes Lagergehäuse 30 geworfen werden können.Immediately adjacent to the portioning and filling device 40, an insertion opening 33 can be seen, which is closed with a strip curtain and through which the bags 3 filled and sealed with small ice cream bodies 1 can be thrown into an insulated bearing housing 30.

Im Lagergehäuse 30 erkennt man zunächst eine an Federn 32 aufgehängte, zu einer Entnahmeöffnung 34 schräg geneigte Rutschplatte 31. Diese Rutschplatte 31 kann sich unter dem Gewicht der gefüllten Beutel 3 bis auf den Boden 38 absenken. Dadurch wird erreicht, daß die gefüllten Beutel 3 sich immer im Bereich der Entnahmeöffnung 34 sammeln, was die Entnahme der Beutel 3 durch eine Bedienungsperson erheblich vereinfacht. Bei großen Kapazitäten des Lagergehäuses 30 ist diese Funktion praktisch unverzichtbar.In the bearing housing 30 one can first see a slide plate 31 suspended from springs 32 and inclined towards a removal opening 34. This slide plate 31 can lower under the weight of the filled bags 3 to the bottom 38. It is thereby achieved that the filled bags 3 always collect in the area of the removal opening 34, which considerably simplifies the removal of the bags 3 by an operator. With large capacities of the bearing housing 30, this function is practically indispensable.

Die Entnahmeöffnung 34 ist mit einer Schwenkklappe verschlossen.The removal opening 34 is closed with a swivel flap.

Oberhalb der Entnahmeöffnung 34 erkennt man eine Kältemaschine 36 mit Verdampfer 37, die einen Kaltluftschleier 35 erzeugen, der das Eindringen von Warmluft beim Öffnen der Entnahmeklappe verhindert. Es versteht sich, daß ein Kaltluftschleier auch im Bereich der Einwurföffnung 33 erzeugt werden kann.Above the removal opening 34 one can see a refrigeration machine 36 with an evaporator 37, which generate a cold air curtain 35 which prevents the penetration of warm air when the removal flap is opened. It goes without saying that a cold air curtain can also be generated in the region of the insertion opening 33.

Im übrigen sorgt die Kältemaschine 36 dafür, daß die Lagertemperatur im Lagergehäuse 30 unterhalb des Gefrierpunktes, beispielsweise bei -5 Grad C, gehalten wird, damit die Kleineiskörper 1 in den geschlossenen Beuteln 3 nicht schmelzen.Otherwise, the refrigeration machine 36 ensures that the storage temperature in the bearing housing 30 is kept below freezing, for example at -5 degrees C., so that the small ice cream bodies 1 do not melt in the closed bags 3.

Wie schon erwähnt, läßt sich diese Vorrichtung in praktisch jeder beliebigen Größe und Kapazität herstellen, jeweils angepaßt an den Verbrauch vor Ort. Die Bedienung der Vorrichtung ist einfach. Das Abpacken der Kleineiskörper in die Beutel erfolgt hygienisch einwandfrei. Die Kälteverluste und damit der Energiebedarf sind minimal.As already mentioned, this device can be produced in practically any size and capacity, in each case adapted to the consumption on site. The operation of the device is simple. The small ice cream bodies are packaged in the bags in a hygienic manner. The cold losses and thus the energy requirement are minimal.
