Description

Eismaschine ice cream machine

Die Erfindung richtet sich auf eine Maschine zur Zubereitung von Speiseeis, insbesondere von Softeis.The invention relates to a machine for the preparation of ice cream, in particular soft ice cream.

Neben dem direkt von einer Eismaschine abgegebenen Softeis gibt es das zumeist in Kugelportionen verkaufte Eis aus der Eisvitrine. Dessen Herstellung hat kraft gesetzlicher Regelungen aus hygienischen Gründen in einem nur für die Eisproduktion reservierten Raum zu erfolgen, der als Eislabor bezeichnet wird. Dies bringt einen nicht unerheblichen, finanziellen Aufwand mit sich, insbesondere in Form eines Mietzuschlags für einen solchen, nur vergleichsweise selten benutzten Raum, in welchem dann eine Maschine zum chargenweisen Einfrieren der verschiedenen Eismischungen betrieben wird.In addition to the soft ice cream that is delivered directly from an ice cream machine, there is also ice cream that is mostly sold in spherical portions. Due to hygienic reasons, its manufacture must take place in a room reserved only for ice cream production, which is referred to as an ice cream laboratory. This entails a not inconsiderable financial outlay, in particular in the form of a rent surcharge for such a space, which is only used comparatively rarely, in which a machine for batch-wise freezing the various ice cream mixtures is then operated.

Aus diesem Nachteil resultiert das die Erfindung initiierende Problem, eine Möglichkeit zu schaffen, wie die Kosten für ein solches Eislabor gesenkt werden können.This disadvantage results in the problem initiating the invention of creating a way of reducing the cost of such an ice laboratory.

Die Lösung dieses Problems gelingt dadurch, dass in oder an der Maschine ein abgeschlossenes oder abschließbares Eislabor oder eine abgeschlossene oder abschließbare Eiswanne ein- oder angebaut oder ein- oder anbaubar ist.The solution to this problem is achieved in that a locked or lockable ice laboratory or a locked or lockable ice pan is built in or attached to or on the machine.

Dadurch wird das Eislabor von der Größe eines Raums reduziert auf die Größe eines Abteils einer Eismaschine, in der insbesondere eine Wanne für das gefrorene Eis Platz hat, oder eine abgeschlossene oder abschließbare Eiswanne selbst fungiert als Eislabor. Bei der ersten Ausführungsform wird nach Einstellen einer leeren Wanne in ein solches Eislabor-Abteil einer Eismaschine das betreffende Abteil verschlossen, ggf. sogar luftdicht, um Kontaminationen mit Bakterien oder sonstigen Krankheitserregern auszuschließen. Das betreffende Eislabor-Abteil oder auch eine anbaubare Eiswanne kann über eine eigene Kühleinrichtung verfügen oder mittels Kontaktkühlung gekühlt/tiefgekühlt werden. In die eingesetzte oder angebaute Eiswanne mündet eine Ausgabevorrichtung für Erfindungsgemäß ist weiter vorgesehen, dass die Eismaschine nach dem Softeismaschinenprinzip arbeitet, d.h., das eigentliche Einfrieren erfolgt nicht chargenweise, sondern kontinuierlich während des Transports durch ein gekühltes Rohr, durch welches die Eismischung mit einer Fördereinrichtung, bspw. einer Förderschnecke, transportiert wird.As a result, the ice laboratory is reduced in size to the size of a compartment of an ice machine, in which in particular a tub for the frozen ice has space, or a locked or lockable ice tub itself functions as an ice laboratory. In the first embodiment, after an empty tub has been placed in such an ice laboratory compartment of an ice machine, the compartment in question is closed, possibly even airtight, in order to exclude contamination with bacteria or other pathogens. The relevant ice laboratory compartment or an attachable ice cream tub can have its own cooling device or can be cooled / deep-frozen by means of contact cooling. An output device for opens into the inserted or attached ice tub According to the invention, it is further provided that the ice cream machine works according to the soft ice cream machine principle, that is to say the actual freezing does not take place in batches, but continuously during transport through a cooled tube through which the ice cream mixture is transported with a conveyor device, for example a screw conveyor.

Aus diesem Grund kann die erfindungsgemäße Eismaschine auch als Softeismaschine betrieben werden, wenn - ggf. anstelle des Eislabor-Abteils - wenigstens ein Eiszapfventil vorgesehen ist.For this reason, the ice cream machine according to the invention can also be operated as a soft ice cream machine if - if necessary instead of the ice cream laboratory compartment - at least one icicle valve is provided.

Die Eiszapfventile können auf einer Montageplatte od. dgl. zu einer Baugruppe zusammengefaßt sein, die von der Eismaschine lösbar ist. An die sodann freien Eisabgabeanschlüsse kann bspw. ein mit einer Eiswanne eines Eislabor-Abteils zu koppelndes Ventil angesetzt werden, das bspw. mit dem lösbaren Eislabor- Abteil integriert ist und bei dessen Montage an der Eismaschine automatisch in dichten Kontakt mit einem Eisabgabeanschluß tritt. Wird sodann eine Eiswanne eingesetzt, kann der Abfüllvorgang ausgelöst werden.The icicle valves can be combined on a mounting plate or the like to form an assembly which can be detached from the ice machine. A valve to be coupled to an ice tub of an ice laboratory compartment can be attached to the then free ice delivery connections, for example, which is integrated with the detachable ice laboratory compartment and automatically comes into tight contact with an ice delivery connection when it is mounted on the ice machine. If an ice pan is then used, the filling process can be triggered.

Andererseits kann nach Lösen der Zapfventil-Baugruppe stattdessen ein Adapter anbaubar sein, an/mit dem eine Eiswanne befestigbar ist. Ein solcher Adapter kann die Funktion des Abstützens übernehmen wie auch ggf. des Abdichtens einer daran festlegbaren Eiswanne.On the other hand, after loosening the nozzle assembly, an adapter can be attached instead, to which an ice pan can be attached. Such an adapter can take on the function of supporting as well as, if necessary, sealing an ice pan which can be fixed thereon.

Bevorzugt verfügt eine an einem derartigen Adapter festlegbare Eiswanne über einen lösbaren Deckel, der sodann die Entnahmeöffnung freigibt. In diesem Deckel, ggf. aber auch an einer anderen Stelle der Eiswanne, kann eine vorzugsweise abdichtbare Anschluß- oder Durchführungsmöglichkeit für die Eisabgabeeinrichtung vorgesehen sein.An ice pan which can be fixed to such an adapter preferably has a detachable cover which then releases the removal opening. In this lid, but possibly also at another point in the ice pan, a preferably sealable connection or feed-through possibility for the ice dispensing device can be provided.

Bei einer anderen Ausführungsform ist das Eislabor-Abteil innerhalb der Eismaschine statisch angeordnet. Es kann von der selben Eisfördereinrichtung befüllt werden, die ansonsten zur Abgabe von Softeis durch Eiszapfventile dient. Dazu ist in dem Förderkanal eine Weiche oder ein Umschaltventil angeordnet, das bspw. auf Knopfdruck umschaltet von Softeisabgabe auf Eisabgabe in die Eiswanne innerhalb des Eislabor-Abteils.In another embodiment, the ice laboratory compartment is arranged statically within the ice machine. It can be filled by the same ice conveyor that is otherwise used to dispense soft ice through icicle valves. For this purpose, a switch or a changeover valve is arranged in the delivery channel for example, at the push of a button, switches from soft ice cream delivery to ice delivery in the ice cream tub within the ice laboratory compartment.

An der erfindungsgemäßen Eismaschine kann außerdem eine Einrichtung zur Herstellung von Schlagsahne vorgesehen sein. Diese Einrichtung ist bevorzugt fördertechnisch von der eigentlichen Eismaschine entkoppelt, so dass bspw. gleichzeitig zu einem Eiseinfriervorgang Schlagsahne produziert werden kann.A device for producing whipped cream can also be provided on the ice cream machine according to the invention. This device is preferably decoupled from the actual ice machine in terms of conveyor technology, so that, for example, whipped cream can be produced at the same time as an ice freezing process.

Bei letzterer Ausführungsform kann - neben einer Einfrier-Kühleinrichtung - auch eine Kühleinrichtung für Temperaturen oberhalb des Celsius-Nullpunktes vorgesehen sein, die für alle Wannen zur Aufnahme einer Eismischung oder der flüssigen Sahne gemeinsam sein kann.In the latter embodiment, in addition to a freezing cooling device, a cooling device for temperatures above zero Celsius can also be provided, which can be common to all trays for holding an ice cream mixture or the liquid cream.

Weitere Merkmale, Einzelheiten, Vorteile und Wirkungen auf der Basis der Erfindung ergeben sich aus den beigefügten Unteransprüchen, ferner aus der nachfolgenden Beschreibung einer bevorzugten Ausführungsform der Erfindung sowie anhand der Zeichnung. Hierbei zeigt:Further features, details, advantages and effects on the basis of the invention emerge from the attached subclaims, further from the following description of a preferred embodiment of the invention and with reference to the drawing. Here shows:

Fig. 2 die Eismaschine aus Fig. 1 in der Seitenansicht und bei angebautem Eislabor; sowieFIG. 2 shows the ice machine from FIG. 1 in a side view and with an ice laboratory attached; such as

Fig. 3 einen Schnitt durch eine andere Ausführungsform der Erfindung mit in der Eismaschine integriertem Eislabor.3 shows a section through another embodiment of the invention with an ice laboratory integrated in the ice machine.

Die Eismaschine 1 aus den Fig. 1 und 2 kann wie eine herkömmliche Softeismaschine verwendet werden. Sie verfügt über ein oder mehrere, von der Oberseite befüllbare und mit Deckeln 2 verschließbare Wannen 3 zur Aufnahme verschiedener Eismischungen. Über eine integrierte Fördereinrichtung, bspw. eine Förderschnecke, gelangt das Eis - während es gekühlt und dadurch gefroren wird - zu den Eiszapfventilen 4. Dort kann es über Düsen 5 in Eishörnchen 6 abgegeben werden; zur Vermeidung von Eistropfen auf dem Fußboden 7 ist ein Abtropfplateau 8 vorgesehen, das auch als Abstellfläche verwendbar ist. Die Eishörnchen oder -waffeln 6 werden in einer oder mehreren vertikalen Röhren 9 bereitgehalten. Dank unterseitiger, vorzugsweise lenk- und ggf. feststellbarer Rollen oder Räder 10 kann die Eismaschine 1 an jeden gewünschten Ort gefahren werden.The ice machine 1 of FIGS. 1 and 2 can be used like a conventional soft ice cream machine. It has one or more trays 3 which can be filled from the top and which can be closed with lids 2, for holding various ice cream mixtures. Via an integrated conveying device, for example a screw conveyor, the ice - while it is being cooled and thereby frozen - reaches the icicle valves 4. There it can be discharged into nozzles 5 in ice cream cones 6; to avoid ice drops on the floor 7 is a Draining plateau 8 is provided, which can also be used as a storage space. The ice cream cones or waffles 6 are kept ready in one or more vertical tubes 9. Thanks to casters or wheels 10 on the underside, which are preferably steerable and possibly lockable, the ice machine 1 can be moved to any desired location.

Alle Eiszapfventile 4 und -abgabedüsen 5 sind auf einer Montageplatte 11 zusammengefaßt, die mittels Schrauben 12 an der Vorderseite 13 der Eismaschine 1 befestigt ist. Nach Lösen dieser Schrauben 12 kann die gesamte Eiszapfbaugruppe 22 von der Eismaschine 1 entfernt werden, um Platz zu schaffen für ein anbaubares Eislabor-Abteil 14, das in Fig. 2 zu sehen ist. Dieses Abteil 14 hat etwa die Form eines Quaders und ist mit einem Deckel 15 verschließbar, der bspw. an einem Scharnier 16 angelenkt sein kann. Der Deckel kann zum Verschluß einer Öffnung an der Vorderseite oder an der Oberseite des Eislabor-Abteils 14 dienen.All icicle valves 4 and dispensing nozzles 5 are combined on a mounting plate 11 which is fastened to the front 13 of the ice machine 1 by means of screws 12. After loosening these screws 12, the entire icicle assembly 22 can be removed from the ice machine 1 in order to make room for an attachable ice laboratory compartment 14, which can be seen in FIG. 2. This compartment 14 has approximately the shape of a cuboid and can be closed with a cover 15, which can be hinged to a hinge 16, for example. The lid can serve to close an opening on the front or on the top of the ice laboratory compartment 14.

Eine direkt unterhalb der abnehmbaren Montageplatte 11 vorgesehene Kühleinrichtung kühlt das Eislabor 14 auf Temperaturen unter dem Gefrierpunkt. Ein rückwärtiger Eisströmungskanal 17 tritt beim Anbau des Eislabors 14 in Flußverbindung mit der maschinenseitigen Eisfördereinrichtung. An dem Eisströmungskanal 17 kann ein reagierendes Ventil vorgesehen sein, so dass nach Einsetzen einer Eiswanne 18 in das Eislabor 14 und Zurückschieben desselben gegen den Eisströmungskanal 17 das betreffende Ventil geöffnet werden kann, woraufhin dann die Befüllung der Eiswanne 18 beginnt.A cooling device provided directly below the removable mounting plate 11 cools the ice laboratory 14 to temperatures below the freezing point. A rear ice flow channel 17 comes into flow connection with the machine-side ice conveying device when the ice laboratory 14 is attached. A reacting valve can be provided on the ice flow channel 17, so that after an ice pan 18 has been inserted into the ice laboratory 14 and pushed back against the ice flow channel 17, the valve in question can be opened, whereupon the filling of the ice pan 18 begins.

Zusätzlich kann an der Eismaschine 1 eine Einrichtung zur Zubereitung von Sahne vorgesehen sein, nämlich eine oberseitige Vorratswanne 19 für flüssige Sahne und eine Sahnezapfstation 20. Dazwischen befindet sich eine Fördereinrichtung mit Schlagwerk. Um den Sahnevorrat zu kühlen, kann die betreffende Wanne 19 zusammen mit den Eisvorratswannen 3 mit einer gemeinsamen Kühleinrichtung gekoppelt sein. Zur Steuerung und Koordination aller Einrichtungen der Eismaschine 1 dient ein Steuerwerk, vorzugsweise in Form eines Mikroprozessors, das auch über ein Tastenfeld 21 bedienbar ist.In addition, a device for preparing cream can be provided on the ice cream machine 1, namely a top-side storage trough 19 for liquid cream and a cream dispensing station 20. In between there is a conveyor device with a striking mechanism. In order to cool the cream supply, the relevant tray 19 can be coupled together with the ice storage trays 3 to a common cooling device. A control unit, preferably in the form of a microprocessor, which can also be operated via a keypad 21, serves to control and coordinate all devices of the ice machine 1.

Die Eismaschine 23 unterscheidet sich von der Eismaschine 1 vor allem dadurch, dass die Eiszapf-Baugruppe 22 nicht abnehmbar ist. Das Eislabor-Abteil 24 ist bei dieser Ausführungsform fest integriert, und zwar unterhalb eines etwa bis zur Vorderkante des Abtropfplateaus 8 nach vor verlagerten Bereichs 25 der Maschinenvorderseite 13. Das Eislabor-Abteil 24 ist mit einer Klappe oder Tür 26 verschließbar und kann direkt gekühlt sein. Eine darin plazierte Eiswanne 18 wird vorzugsweise von ihrer Oberseite her befüllt, entweder bei abgenommenem Wannendeckel oder durch eine abgedichtete Öffnung in demselben hindurch. Der betreffende Eisströmungskanal 27 zweigt an einer Weiche oder einem Umschaltventil 28 von dem Eisförderkanal 29 zwischen Eisvorratswanne 3 und Eiszapfventil 4 ab, und zwar stromabwärts einer Fördereinrichtung, insbesondere Förderschnecke 30, in deren Bereich sich auch die Kühleinrichtung zum Einfrieren befindet. The ice machine 23 differs from the ice machine 1 primarily in that the icicle assembly 22 is not removable. In this embodiment, the ice laboratory compartment 24 is firmly integrated, namely below an approximately up to the front edge of the drip tray 8 toward the front of the displaced region 25 of the machine front 13. The ice laboratory compartment 24 can be closed with a flap or door 26 and can be cooled directly , An ice pan 18 placed therein is preferably filled from the top, either with the pan lid removed or through a sealed opening therein. The ice flow channel 27 in question branches off at a switch or a changeover valve 28 from the ice delivery channel 29 between the ice storage trough 3 and the icicle valve 4, namely downstream of a delivery device, in particular a screw conveyor 30, in the area of which the cooling device for freezing is also located.
