Abstract

The device consists of a rotating hollow roller (10) and a pressure roller (16) running inside it. The inside of the hollow roller has shaped annular grooves (12) with which engage correspondingly shaped annular ribs (18) on the pressure roller (16). Discharge through-holes (14) in the shaped grooves (12) distributed at a predetermined angular distance around the periphery of the roller open through the roller jacket. The hollow roller (10) rotates and thus the pressure roller (16) runs on the inner jacket. The material enters the pressing gap via the product feed pipe (22) and the slots (24) therein and is pressed out through the holes (14). It falls on a cooled conveyor belt (40) by which the pastilles (38) are taken away.

Description

Vorrichtung zur Erzeugung von Granalien oder Pastillen aus fließfähigem Material Device for producing granules or pastilles from flowable material

Die Erfindung bezieht sich auf eine Vorrichtung zur Erzeugung von Granalien oder Pastillen aus fließfähigem Material mit eine umlaufenden, mit Preßausnehmungen und radial nach außen an¬ schließenden Auspreßlöchern versehenen Hohlwalze und einer an deren Innenseite ablaufenden Preßwalze, dae mit Preßwerkzeugen in die Preßausnehmungen eingreift und das dem Preßspalt zuge¬ führte Material durch die Auspreßlöcher auspreßt, das in Form von Granalien oder Pastillen auf einer darunter befindlichen Kühlfläche abgelegt wird.The invention relates to a device for producing granules or lozenges from flowable material with a circumferential hollow roller provided with pressing recesses and radially outwardly adjoining pressing holes and a pressing roller running on the inside thereof, which engages with pressing tools in the pressing recesses and that Press nip supplied material is squeezed through the squeezing holes and is deposited in the form of granules or pastilles on a cooling surface located underneath.

Eine derartige Vorrichtung ist aus der DE 39 02 957 Cl bekannt. Hierbei sind die Preßwerkzeuge als Außenverzahnung der Preß- walze ausgebildet und die Preßausnehmungen werden von einerSuch a device is known from DE 39 02 957 Cl. Here, the press tools are designed as external teeth of the press roll and the press recesses are one

Innenverzahnung der Hohlwalze gebildet, in die die Außenverzah¬ nung der Preßwalze eingreift, so daß jeweils ein Preßwerkzeug in Gestalt eines Zahnes mit einer Preßausnehmung und einem Aus- .preßloch zusammenwirkt. Vorrichtungen dieser Art haben sich für die meisten Materialien als zweckmäßig und zuverlässig erwiesenInternal toothing of the hollow roll is formed, in which the outer toothing of the press roll engages, so that in each case a press tool in the form of a tooth interacts with a press recess and a press-out hole. Devices of this type have proven to be useful and reliable for most materials

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung hinsichtlich des Zusammenwirkens von Hohlwalze und Preßwalze so auszubilden, daß eine weitere Viel- falt von Materialien, insbesondere niedrig- bis mittelviskose Stoffe zuverlässig auch zu kleinen bis mittelgroßen Pastillen pastilliert werden können.The present invention is based on the object of designing a generic device with regard to the interaction of the hollow roller and the press roller in such a way that a further variety of materials, in particular low- to medium-viscosity substances, can be reliably pastilled into small to medium-sized lozenges.

Gelöst wird die gestellte Aufgabe durch die im Kennzeichnungs- teil des Patentanspruchs 1 angegebenen Merkmale.The problem is solved by the features specified in the characterizing part of claim 1.

Es hat sich gezeigt, daß durch den gegenseitigen Eingriff von Rippen und Nuten eine günstige Bearbeitung aller in Frage kommenden Stoffe möglich ist, wobei eine Anpassung auf die jeweiligen Stoffe durch spezielle Gestaltung des Querschnitts von Rippen und Nuten gewährleistet werden kann. Die Ausbildung der Rippen und Nuten ergibt gegenüber den Innen- und Außenver- zahnungen der bekannten Vorrichtung eine wesentliche Verein¬ fachung der Herstellung.It has been shown that by the mutual engagement of ribs and grooves, a cheap machining of all in question coming fabrics is possible, whereby an adaptation to the respective fabrics can be guaranteed by special design of the cross section of ribs and grooves. The formation of the ribs and grooves results in a significant simplification of manufacture compared to the internal and external toothing of the known device.

Es hat sich gezeigt, daß durch die erfindungsgemäße Anordnung eine günstige Verteilung und ein günstiges Austragen ergibt, wobei ein Materialfluß innerhalb jeder Nut erfolgen kann, weil die Preßwerkzeuge nicht mehr nur jeweils einem Preßloch zuge¬ ordnet sind. Abhängig von der zu verarbeitenden Materialart kann es zweckmäßig sein, den Winkelabstand der Löcher und/oder ihren Durchmesser individuell einzustellen.It has been shown that the arrangement according to the invention results in a favorable distribution and a favorable discharge, a material flow being able to take place within each groove, because the pressing tools are no longer assigned to only one pressing hole. Depending on the type of material to be processed, it may be appropriate to individually adjust the angular spacing of the holes and / or their diameter.

Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Useful embodiments of the invention result from the subclaims.

Beispielsweise aus der FR-PS 1 459 319 ist es zwar zur Verarbei- tung pulverförmiger Massen zu Granalien bekannt, mindestens zwei Walzen mit ineinandergreifenden umlaufenden Profilnuten und Ringrippen zu versehen, wobei die zusammenwirkenden Walzen mit ihren Achsen in einer gemeinsamen horizontalen Ebene angeordnet sind und sich der Preßspalt zwischen diesen Walzen in Vertikal- richtung erstreckt. Das pulverförmige Material wird teilweise vor dem Durchlaufen der Walzen durch Befeuchten auf eine plastische Konsistenz gebracht. Die Verwendung einer derartigen Vorrichtung zur Verarbeitung von fließfähigem Material ist jedoch nicht möglich, da hierbei das Material durch die zwischen den beiden Walzen gebildeten Preßspalte hinduchfließen würde und keine einzelnen Granalien erzeugt werden könnten, sondern das Material allenfalls in Form von Strängen auf einem ggf. vorge¬ sehenen Kühlband abgelegt würde.For example, from FR-PS 1 459 319 it is known for the processing of powdery masses into granules to provide at least two rollers with interlocking circumferential profile grooves and ring ribs, the interacting rollers being arranged with their axes in a common horizontal plane the press nip between these rollers extends in the vertical direction. The powdery material is partially brought to a plastic consistency by moistening before passing through the rollers. However, the use of such a device for processing flowable material is not possible, since this would cause the material to flow through the press nips formed between the two rolls and no individual granules could be produced, but rather the material in the form of strands on a possibly pre-cut ¬ seen cooling belt would be stored.

Nachstehend werden Ausführungsbeispiele der Erfindung anhand der Zeichnung beschrieben. In der Zeichnung zeigen: Fig. 1 eine schematische Querschnittsansicht der erfindungs¬ gemäßen Vorrichtung;Exemplary embodiments of the invention are described below with reference to the drawing. The drawing shows: 1 shows a schematic cross-sectional view of the device according to the invention;

Fig. 2 einen Teillängsschnitt der Vorrichtung nach Fig. 1;FIG. 2 shows a partial longitudinal section of the device according to FIG. 1;

Fig. 3 schematische Darstellungen verschiedener Profillie- rungen der Preßwalze.3 shows schematic representations of various profiles of the press roll.

Die erfindungsgemäße Vorrichtung weist eine Hohlwalze 10 auf, die innen umlaufende, in axialem Abstand zueinander angeordnete Profilnuten 12 als Preßausnehmungen aufweist. Am Boden der Profilnuten 12 münden den Mantel der Walze durchsetzende Aus¬ preßlöcher 14, durch die die Schmelze ausgedrückt wird.The device according to the invention has a hollow roller 10, which has internally circumferential, axially spaced profile grooves 12 as press recesses. At the bottom of the profile grooves 12, through-holes 14 penetrate the jacket of the roller and through which the melt is expressed.

Im Inneren der Hohlwalze läuft eine Preßwalze 16 ab, die mit umlaufenden Ringrippen 18 als Preßwerkzeug versehen ist, und diese im Querschnitt den Profilnuten 12 angepaßten Ringrippen 18 greifen in die Profilnuten ein und pressen das Material durc die Auspreßiöcher 14 aus.In the interior of the hollow roll, a press roll 16 runs, which is provided with circumferential ring ribs 18 as a pressing tool, and these ring ribs 18, which are adapted to the profile grooves 12 in cross section, engage in the profile grooves and press out the material through the press-out holes 14.

Die Preßwalze 16 ist über Lenker 20 an einem die Hohlwalze konzentrisch durchsetzenden Produkt-Zulaufröhr 22 aufgehängt. Durch Schlitze 24 des beheizten Produktzulaufrohres 22 tritt das Material aus und gelangt von dort in den Preßspalt zwischen Hohlwalze und Preßwalze.The press roll 16 is suspended via link 20 from a product feed pipe 22 which concentrically penetrates the hollow roll. The material exits through slots 24 of the heated product feed pipe 22 and from there reaches the press nip between the hollow roll and the press roll.

Zur Mitnahme der Preßwalze 16 ist auf deren Welle 26 ein Stirn¬ rad 28 aufgesetzt, das mit einem Innenzahnkranz 29 der Hohlwalze kämmt. Die Preßwalze 16 ist über eine exzentrische Anordnung höhenverstellbar, um die Eingriffstiefe zwischen Ringrippen und Profilnuten verändern zu können.To take the press roll 16, a spur gear 28 is placed on its shaft 26, which meshes with an internal ring gear 29 of the hollow roll. The press roller 16 is height adjustable via an eccentric arrangement in order to be able to change the depth of engagement between the ring ribs and profile grooves.

Ein Teil des Umfangs der Hohlwalze ist mit einem Heizmantel 30 umgeben, der gleichzeitig als Absaugschacht 32 für die sich entwickelnden Gase ausgebildet ist. Diese Anordnung kann gemäß der DE-ÖS 40 13 405 ausgebildet sein. Ein Be älter-Produkteinweiser 34 ist über einem vom Heizmantel 30 freien Winkelabschnitt der Hohlwalze angeordnet, und dieser hat die Aufgabe, das überschüssige Produkt abzustreifen und schließlich wieder über Bohrungen der Hohlwalze zuzuführen. Für die Ausbildung ist der sich ergebende Spalt 36 von großer Bedeu¬ tung, und dieser wird je nach Viskosetat der zu verarbeitenden Produkte ermittelt.A part of the circumference of the hollow roller is surrounded by a heating jacket 30, which is designed at the same time as a suction shaft 32 for the developing gases. This arrangement can be designed according to DE-ÖS 40 13 405. A loading older product guide 34 is arranged over an angular section of the hollow roller which is free from the heating jacket 30, and this has the task of stripping off the excess product and finally feeding it back in through holes in the hollow roller. The resulting gap 36 is of great importance for the formation, and this is determined depending on the viscose acetate of the products to be processed.

Die durch die Auspreßlöcher 14 ausgedrückten und so erzeugten Granalien oder Pastillen 38 werden auf einer unterhalb derThe granules or pastilles 38, which are expressed through the squeezing holes 14 and thus produced, are placed on one below the

Hohlwalze angeordneten bewegten u. gekühlten Fläche 40 abgelegt, die als Kühlband oder als Kühlwalze ausgebildet sein kann.Hollow roller arranged moving u. cooled surface 40 stored, which can be designed as a cooling belt or as a cooling roller.

In Fig. 3 sind einige denkbare Profilformen der Ringrippen der Preßwalze angegeben. Die Ringrippe 181 hat den Querschnitt eines gleichschenkligen Dreiecks. Die Ringrippe 182 hat die Form eines gleichseitigen Trapezes .In Fig. 3 some conceivable profile shapes of the ring ribs of the press roll are given. The annular rib 181 has the cross section of an isosceles triangle. The ring rib 182 has the shape of an equilateral trapezoid.

Die Ringrippe 183 besitzt konvergierende Seitenflächen, die durch einen Bogen überbrückt sind.The annular rib 183 has converging side surfaces which are bridged by an arc.

Der Querschnitt der Ringrippe 184 hat die Form eines gleichseitigen Dreiecks, wobei die Basis nach innen versetzt ist, so daß zwischen benachbarten Rippen 184 auf der Walze um- laufende zylindrische Ringflächen gebildet werden. Derartige zylindrische Ringflächen zwischen benachbarten Rippen werden auch bei den Ringrippen 185 gebildet, deren Profil rechteckig ist.The cross section of the ring rib 184 has the shape of an equilateral triangle, the base being offset inwards, so that cylindrical ring surfaces are formed on the roller between adjacent ribs 184. Such cylindrical ring surfaces between adjacent ribs are also formed in the ring ribs 185, the profile of which is rectangular.

Der Querschnitt der Profilnuten 12 entspricht jeweils demThe cross section of the profile grooves 12 corresponds to that

Querschnitt der hiermit zusammenwirkenden Ringrippen. Es kann sich jedoch,, unter gewissen Umständen auch als zweckmäßig er¬ weisen, unterschiedlich profillierte Profilnuten und Ringrippen¬ zusammenwirken zu lassen.Cross section of the ring ribs interacting with it. However, under certain circumstances it can also be expedient to have differently profiled profile grooves and annular ribs interact.

Die erfindungsgemäße Vorrichtung eignet sich insbesondere zur Verarbeitung Niedrig- bis Mittelviskose-Stof e, wobei kleine bis mittelgroße Pastillen hergestellt werden. The device according to the invention is particularly suitable for processing low to medium-viscosity substances, whereby small to medium-sized lozenges are produced.
