Description

Die Erfindung betrifft einen Verkaufsautomaten für essfertige, warme oder heiße Speisen, welche in dem Automaten gekühlt oder tiefgekühlt gelagert wurden. Typische Speisen, welche mit dem erfindungsgemäßen Verkaufsautomaten in vorteilhafter Weise gelagert und verkauft werden können sind Pizzastücke.The invention relates to a vending machine for ready-to-eat, hot or hot dishes, which were stored in the machine refrigerated or frozen. Typical foods that can be stored and sold in an advantageous manner with the vending machine according to the invention are pizza pieces.

In Verkaufsautomaten, in denen rasch Lebensmittel vom gekühlten oder tiefgekühlten Zustand in einen heißen, essfertigen Zustand gebracht werden sollen, werden üblicherweise Mikrowellenherde, oftmals in Kombination mit Heißluft verwendet. Lebensmittel bei denen eine Backkruste wünschenswert ist, werden schon vor dem Kühlen oder Gefrieren entsprechend vorgebacken. Der Geschmack der so erhitzten, aus einem Verkaufsautomaten erhaltenen Lebensmittel, kann aber nicht mit Lebensmitteln mithalten, welche tatsächlich unmittelbar vor der Übergabe zum Verzehr fertig gebacken wurden.In vending machines, where foodstuffs are to be rapidly brought from the chilled or frozen state into a hot, ready-to-eat state, microwave ovens are often used, often in combination with hot air. Foods where a baked crust is desirable are pre-baked before cooling or freezing. The taste of the food so heated, obtained from a vending machine, but can not compete with food, which was actually baked ready for consumption immediately before the handover.

Die der Erfindung zu Grunde liegende Aufgabe besteht darin, einen Ofen bereit zu stellen, welcher in einem Verkaufsautomaten verwendbar ist um Speisen innerhalb sehr kurzer Zeit, typischerweise weniger als drei Minuten, von einem nicht fertig gebackenen, gekühlten oder tiefgekühlten Zustand in einen heißen, fertig gebackenen Zustand über zu führen, ohne dabei Mikrowellenstrahlung anzuwenden.The object underlying the invention is to provide an oven which can be used in a vending machine to turn food from a non-finished baked, chilled or frozen state into a hot one within a very short time, typically less than three minutes baked state, without applying microwave radiation.

Zum Erfüllen der Aufgabe wird vorgeschlagen, einen Ofen zu verwenden, welcher eine Einrichtung zum Erhitzen von Luft und eine Einrichtung zum Bewegen von Heißluft durch den Backraum enthält, sowie zwei Infrarotstrahlungsquellen die mit Infrarotstrahlung in unterschiedlichen Spektralbereichen von oben und von unten auf eine im Ofen zu erhitzende Speise strahlen. Dabei ist die Infrarotstrahlungsquelle mit der langwelligeren Strahlung im Backraum unterhalb der Speise angeordnet und die Infrarotstrahlungsquelle mit der kurzwelligeren Strahlung im Backraum oberhalb der Speise. Gute Ergebnisse werden erzielt, wenn die untere Infrarotstrahlungsquelle dazu in der Lage ist mit einer Strahlungsleistung von 3 bis 8 W je cm2 Grundfläche der zu erhitzenden Speise Infrarotstrahlung nach oben zu senden, wobei die Strahlungsenergie zu mehr als 50% in Strahlung mit einem Wellenlängenbereich von 5 bis 10 µm liegt und wenn die obere Infrarotstrahlungsquelle dazu in der Lage ist mit einer Strahlungsleistung von 5 bis 10 W je cm2 Grundfläche der zu erhitzenden Speise Infrarotstrahlung nach unten zu senden, wobei die Strahlungsenergie zu mehr als 50% in Strahlung mit einer Wellenlänge von weniger als 3 µm liegt.To achieve the object, it is proposed to use an oven which includes a means for heating air and means for moving hot air through the baking chamber, and two infrared radiation sources with infrared radiation in different spectral ranges from above and from below to one in the oven radiate warming food. In this case, the infrared radiation source is arranged with the long-wave radiation in the oven below the food and the infrared radiation source with the short-wave radiation in the oven above the food. Good results are achieved when the lower infrared radiation source is able to transmit up to a radiant power of 3 to 8 W per cm 2 of surface area of the food to be heated infrared radiation, wherein the radiation energy to more than 50% in radiation with a wavelength range of 5 to 10 microns, and if the upper infrared radiation source is able to transmit with a radiant power of 5 to 10 W per cm 2 base area of the food to be heated infrared radiation downwards, wherein the radiation energy to more than 50% in radiation with a wavelength is less than 3 microns.

Further advantageous details are explained with reference to a drawing:

shows an oven according to the invention in oblique view from the front, and for reasons of clarity, the oven door located on the front side is not shown.

Das quaderförmige äußere Gehäuse 1 dient neben der mechanischen Halterung vorwiegend zur Wärmeisolation. Typischerweise kann es aus zwei Schichten Stahlblech mit einer dazwischen befindlichen isolierenden Schicht, die beispielsweise aus Steinwolle bestehen kann, aufgebaut sein.The cuboid outer housing 1 is used in addition to the mechanical support mainly for heat insulation. Typically, it may be constructed of two layers of steel sheet with an insulating layer therebetween, which may be rockwool, for example.

Der Backraum 2 des Ofens ist innerhalb des äußeren Gehäuses durch eine quaderförmige Mantelfläche 3 abgegrenzt, wobei sich zwischen der inneren Fläche des Gehäuses 1 und der demgegenüber deutlich kleineren Mantelfläche 3 des Backraumes ein weitgehend leerer Zwischenraum 4 erstreckt, welcher vorwiegend zum Leiten von Heißluft dient. Vom Backraum 2 zum Zwischenraum 4 kann Heißluft durch Schlitze in der Bodenfläche der Mantelfläche 3 des Backraumes fließen. Vom Zwischenraum 4 in den Backraum 2 kann Heißluft durch Schlitze in der Deckfläche der Mantelfläche 3 des Backraumes 2 fließen.The baking chamber 2 of the oven is delimited within the outer housing by a cuboid lateral surface 3, wherein between the inner surface of the housing 1 and the contrast significantly smaller lateral surface 3 of the oven a largely empty space 4 extends, which mainly serves for the conduction of hot air. From the oven 2 to the space 4 hot air can flow through slots in the bottom surface of the lateral surface 3 of the oven. From the gap 4 in the baking chamber 2 hot air can flow through slots in the top surface of the lateral surface 3 of the baking chamber 2.

Im Backraum ist etwa auf dessen mittlerer Höhe ein horizontal ausgerichtetes Gitter 5 angeordnet, welches als Auflagefläche für die zu erhitzende Speise 6 vorgesehen ist. Die Grundrissfläche der Speise ist geringfügig kleiner als die Grundrissfläche des Backraums, sodass Heißluft im Backraum an der Speise vorbeiströmen kann.In the baking chamber, a horizontally oriented grid 5 is arranged approximately at the middle level, which serves as a support surface for the food to be heated 6 is provided. The floor plan of the food is slightly smaller than the floor plan of the baking chamber, so that hot air in the oven can flow past the food.

Heißluft wird durch einen unterhalb des Backraums 2 im Zwischenraum 4 angeordneten, in einer horizontalen Ebene rotierenden Radiallüfter 7 bewegt. Der Radiallüfter drängt Luft radial nach außen, sodass sie im Zwischenraum 4 nach oben strömt, durch die oberen Schlitze in der Mantelfläche 3 in den Backraum strömt, durch diesen nach unten strömt und durch die unteren Schlitze in der Mantelfläche 3 wieder zum Radiallüfter 7 gelangt. Da im vorliegenden Anwendungsfall sehr schnell erhitzt werden soll, ist es vorteilhaft, wenn die Heißluft sehr schnell herum bewegt wird. Bei einer typischen Auslegung hat der Radiallüfter einen Durchmesser von etwa 150 mm und kann einen Volumenstrom von bis zu 160 m3/h Luft hervorrufen.Hot air is moved through a arranged below the baking chamber 2 in the intermediate space 4, rotating in a horizontal plane radial fan 7. The radial fan urges air radially outwards, so that it flows upwards in the intermediate space 4, flows through the upper slots in the jacket surface 3 into the baking chamber, flows down through the latter and passes through the lower slots in the jacket surface 3 back to the radial fan 7. Since it should be heated very quickly in the present application, it is advantageous if the hot air is moved around very quickly. In a typical design, the radial fan has a diameter of about 150 mm and can produce a volume flow of up to 160 m 3 / h of air.

Die Heißluft wird vorwiegend durch die im unteren Bereich des O-fenraumes angeordnete Infrarotstrahlungsquelle 8 erhitzt. Diese Infrarotstrahlungsquelle kann typischerweise durch eine Keramikfläche realisiert sein, welche oberflächlich mit Nuten versehen ist, in welche ein Heizdraht ohne weitere Ummantelung eingelegt ist. Gegenüber Anordnungen bei denen der Heizdraht selbst auch mit Keramik ummantelt ist, wird damit eine deutlich schnellere Aufheiz- und Abkühlzeit erreicht, wie es für den vorliegenden Anwendungsfall wichtig ist.The hot air is heated mainly by the arranged in the lower region of the O-fenraumes infrared radiation source 8. This infrared radiation source can typically be realized by a ceramic surface, which is provided on the surface with grooves, in which a heating wire is inserted without further sheathing. Compared to arrangements in which the heating wire itself is also encased in ceramic, so that a much faster heating and cooling time is achieved, as it is important for the present application.

Im oberen Bereich des Backraums 2 ist eine Infrarotstrahlungsquelle 9 angeordnet, welche überwiegend eine kurzwelligere Strahlung aussendet als die untere Infrarotstrahlungsquelle 8. Die Infrarotstrahlungsquelle 9 ist typischerweise durch einen - vorteilhaft rasch regelbaren - Quarzstrahler gebildet.In the upper region of the baking chamber 2, an infrared radiation source 9 is arranged, which emits predominantly a short-wave radiation as the lower infrared radiation source 8. The infrared radiation source 9 is typically formed by a - advantageously quickly controllable - quartz emitter.

Für den Ablauf der Steuerung ist zu empfehlen, den gesamten Backvorgang in drei Zeitabschnitte zu unterteilen. Für jeden Abschnitt können mittels Pulsweitenmodulation oder Phasenanschnittsteuerung angepasste Leistungssollwerte für die an den einzelnen Heizelementen einzubringende elektrische Leistung vorgegeben werden. Natürlich können auch Temperaturen gemessen werden und entsprechend einem Sollverlauf Heizleistungen nachgeregelt werden. Durch die Anordnung von zwei Infrarotstrahlungsquellen ist die Unterscheidung zwischen Ober- und Unterhitze möglich. Da der Ofen innerhalb von typischerweise 20 Sekunden auf eine Start- Betriebstemperatur von über 200°C zu bringen sein soll, ist es sinnvoll, den Backraum im Wartezustand auf einer gewissen, gegenüber der Umgebung erhöhten Temperatur zu halten. Dazu kann die Lufttemperatur überwacht und auf eine Haltetemperatur von beispielsweise 100°C geregelt werden.For the sequence of the control is recommended to divide the entire baking process in three time periods. For each section can by means of pulse width modulation or phase control adjusted power setpoints for the electrical power to be introduced at the individual heating elements. Of course, temperatures can also be measured and heat outputs can be readjusted in accordance with a desired course. The arrangement of two infrared radiation sources makes it possible to distinguish between upper and lower heat. Since the oven is to be brought to a starting operating temperature of over 200 ° C within typically 20 seconds, it makes sense to keep the baking chamber in a waiting state at a certain elevated temperature to the environment. For this purpose, the air temperature can be monitored and regulated to a holding temperature of, for example, 100 ° C.
