Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Aufbereiten von Puffware (also einem bei Erhitzung stark expandie renden, stärkehaltigen Lebensmittel) mit einer Druckkam mer, einer Expansionskammer und einer zwischen dieser angeordneten Trennwandung, wobei die Druckkammer mit Mitteln zu deren Beheizung und Mittel zu deren Be schicken mit der zu expandierenden Ware versehen ist, die Expansionskammer mit einer verschließbaren Ent nahmeöffnung versehen ist und Trennwandung eine schlag artige Öffnung erlaubend ausgebildet ist.The invention relates to a device for processing of puffed goods (i.e. a strong expandie when heated renden, starchy foods) with a pressure mer, an expansion chamber and one between them arranged partition, the pressure chamber with Means for their heating and means for their Be send with the goods to be expanded, the expansion chamber with a lockable Ent receiving opening is provided and partition wall a blow like opening is designed to allow.
Puffware, beispielsweise Popcorn, erfreut sich großer Beliebtheit. Dabei finden zunehmend Geräte Anwendung, bei denen die Puffware vor den Augen des Kunden auf bereitet und diesem also frisch verkauft wird.Puffware, such as popcorn, is more popular Popularity. Devices are increasingly used, where the puffed goods appear in front of the customer is prepared and is therefore sold fresh.
Die bekannten Vorrichtungen zum Aufbereiten von Puffware haben jedoch den Nachteil, daß das Austreten der Ware zur Expansion in die Expansionskammer mit einer erheb lichen Lärmentwicklung verbunden ist.The known devices for processing puffware have the disadvantage, however, that the leakage of the goods to expand into the expansion chamber with a significant increase Lichen development is connected.
Der Erfindung liegt damit die Aufgabe zugrunde, die vor bekannte Vorrichtung dahingehend weiterzubilden, daß die Lärmentwicklung vermindert wird.The invention is therefore based on the object known device to further develop that the Noise is reduced.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Expansionskammer druckdicht ausgebildet ist und Mit tel zum Erzeugen eines Unterdrucks in der Expansions kammer vorgesehen sind.According to the invention this object is achieved in that the expansion chamber is pressure-tight and with tel to create a negative pressure in the expansion chamber are provided.
Gegenstand der Unteransprüche sind bevorzugte Ausfüh rungsbeispiele der Erfindung.The subclaims relate to preferred embodiments tion examples of the invention.
Die Erfindung wird im folgenden anhand einer einzigen Figur erläutert.The invention is described below with reference to a single one Figure explained.
Die Vorrichtung besteht aus einer Druckkammer 2, die mit einer druckdichten Einfüllöffnung 16 versehen ist, über die die Druckkammer 2 mit der zu expandierenden Puffware (beispielsweise Maiskörnern) beschickt wird. Auf die Druckkammer wirkt weiter eine in dem dargestellten Aus führungsbeispiel als Brenner 9 dargestellte Heizung, die mit einem Heizmittelventil 11 versehen ist.The device consists of a pressure chamber 2 , which is provided with a pressure-tight filling opening 16 , through which the pressure chamber 2 is charged with the puffware to be expanded (for example corn kernels). On the pressure chamber also acts from a heater shown in the exemplary embodiment shown as a burner 9 , which is provided with a heating medium valve 11 .
Die Druckkammer 2 wird weiter über ein Heizdampfventil 10 mit Heizdampf beschickt, über die die erforderliche Feuchtigkeit in die Druckkammer 2 eingeführt wird. The pressure chamber 2 is further fed with heating steam via a heating steam valve 10 , via which the required moisture is introduced into the pressure chamber 2 .
Die Druckkammer 2 mündet in eine Expansionskammer 1, deren Volumen weitaus größer als das der Druckkammer 2 ist. Eine Trennwandung 3 trennt dabei den Raum der Druckkammer 2 von dem Raum der Expansionskammer 1, wobei die Trennwandung 3 mit einem Aufpralldämpfer 4 versehen ist, der bei einem Verschwenken der Trennwandung 3 um ein Scharnier 5 gegen ein Gegenlager 6 schlägt.The pressure chamber 2 opens into an expansion chamber 1 , the volume of which is far greater than that of the pressure chamber 2 . A dividing wall 3 separates the space of the pressure chamber 2 from the space of the expansion chamber 1 , the dividing wall 3 being provided with an impact absorber 4 which strikes a counter bearing 6 when the dividing wall 3 is pivoted about a hinge 5 .
Die Trennwandung 3 ist mit einer Verriegelung 7 verse hen, die bei Betätigung einer Rückzugseinrichtung 8 die Trennwandung freigibt, so daß diese aufschlägt.The partition 3 is hen with a locking 7 verses, which releases the partition when actuating a retractor 8 , so that it opens.
Die Expansionskammer ist mit einer Vakuumpumpe 13 verse hen, der ein Kondensator 12 vorgeschaltet. Weiter weist die Expansionskammer 1 einen Auffangkonus 14 auf, der mit einer Vakuumschleuse 15 versehen ist, über die die aufbereitete Puffware entnommen werden kann.The expansion chamber is hen with a vacuum pump 13 verse, which is preceded by a condenser 12 . Furthermore, the expansion chamber 1 has a collecting cone 14 , which is provided with a vacuum lock 15 , via which the processed puffware can be removed.
Zur Aufbereitung von Puffware wird das zu expandierende Produkt über die druckdichte Einfüllöffnung 16 in die Druckkammer 2 eingebracht.For the preparation of puff goods, the product to be expanded is introduced into the pressure chamber 2 via the pressure-tight filling opening 16 .
Durch eine geeignete Zufuhr von Heizdampf und weiteres Erhitzen über die Brenner 9 entsteht in der Kammer 2 ein hoher Druck im Bereich mehrerer bar (größenordnungsmäßig 20 bar). Nach Erreichen dieses Drucks wird die Rückzugs einrichtung 8 betätigt, die Trennwandung 3 schlägt auf und das Gut tritt in die Expansionskammer 1, in der durch Betreiben der Vakuumpumpe 13 ein Unterdruck besteht, aus.A suitable supply of heating steam and further heating via the burners 9 creates a high pressure in the chamber 2 in the range of several bar (of the order of 20 bar). After reaching this pressure, the retraction device 8 is actuated, the partition 3 strikes and the material enters the expansion chamber 1 , in which there is a vacuum by operating the vacuum pump 13 .
Bei diesem Austreten in den Bereich des Unterdrucks in der Expansionskammer 1 expandieren die unter Feuchtig keit stark erhitzten Körner der Puffware schlagartig, sie fallen dann in den Auffangkonus 14 und können über die Zellenradschleuse 15 entnommen werden.When this emerges in the region of the negative pressure in the expansion chamber 1 , the grains of the puffed goods, which are strongly heated under moisture, expand suddenly, they then fall into the collecting cone 14 and can be removed via the rotary valve 15 .
Es hat sich überraschenderweise gezeigt, daß durch die Ausbildung der Expanionskammer 1 als Vakuumkammer die entstehende Geräuschentwicklung weitaus geringer ist. Dies bestätigt theoretische Berechnungen der Schallent wicklung und -übertragung, wonach bei der erfindungs gemäß vorgeschlagenen Ausgestaltung einer Vorrichtung zum Aufbereiten von Puffware nur eine vernachlässigbar geringe Geräuschentwicklung stattfindet.Surprisingly, it has been shown that the development of the expansion chamber 1 as a vacuum chamber results in a much lower noise level. This confirms theoretical calculations of sound development and transmission, according to which only a negligibly low level of noise takes place in the embodiment of a device for processing puffware proposed according to the invention.
