A rib (16) protrudes from each outlet opening (14) in the feed region and ribs also extend between the ring-shaped cavity and connecting bores. The product is supplied to the feed region via a feed pipe (7). The outlet openings in the feed region lead to feed bores (8) communicating with a centrifuge region of the drum (1). The ring-shaped cavity is located above the free end of the feed region.

Description

Die Erfindung betrifft einen Separator nach dem Oberbegriff des Anspruchs 1.The invention relates to a separator according to the preamble of claim 1.

Ein derartiger Separator ist aus der DE 38 34 134 A1 bekannt (siehe Fig. 4).Such a separator is known from DE 38 34 134 A1 (see FIG. 4).

Bei der Entkeimung eines Produktes wie Rohmilch mittels Separatoren kommt es immer wieder zu kurzzeitigen Verschlechterungen der Entkeimungseffizienz aufgrund von Druckanstiegen im Zulauf, die z. B. durch Teilentleerungen, Tankumschaltungen oder durch einen erhöhten Luftgehalt in dem Produkt hervorgerufen werden.When sterilizing a product such as raw milk by means of separators, it always happens again due to short-term worsening of the sterilization efficiency of pressure increases in the inlet, the z. B. by partial discharges, tank switching or caused by an increased air content in the product.

Ein weiteres Problem ist ein Transport (Schaftlauf) von Keimen zur Schälscheibe.Another problem is a transport (shaft run) of germs to the peeling disc.

Die Lösung dieses Problems ist die Aufgabe der Erfindung.The solution to this problem is the object of the invention.

Die Erfindung löst diese Aufgabe durch den Gegenstand des Anspruches 1.The invention solves this problem by the subject matter of claim 1.

Danach erstrecken sich die Verbindungsbohrungen zwischen einem vorzugsweise konischen Zulaufraum und dem Ringraum und vorzugsweise jeder der Austrittsöffnungen aus dem Zulaufraum in die Zulaufbohrungen des Verteilers und jeder der Verbindungsbohrungen zum Ringraum ist jeweils eine Rippe zugeordnet.Thereafter, the connection bores extend between a preferably conical Zulaufraum and the annulus and preferably each of the outlet openings from the inlet space into the inlet bores of the distributor and each of the connection bores to the annulus a rib is assigned in each case.

Mit der Erfindung und insbesondere auch ihren bevorzugten Ausgestaltungen der Unteransprüche wird eine besonders gleichmäßige Annahme und Beschleunigung sowie auch eine besonders gleichmäßige Entlüftung des Produktes erreicht, wodurch auch bei erhöhtem Luftgehalt im Produkt relativ konstante Entlüftungswerte erzielbar sind.With the invention and in particular also its preferred embodiments of the dependent claims will be a particularly uniform assumption and acceleration as well Also achieved a particularly uniform ventilation of the product, which also If the air content in the product is relatively high, relatively constant ventilation values can be achieved.

Besonders vorteilhaft sind nach einer Variante die Rippen radial innerhalb der Austrittsöffnungen aus dem Zulaufraum in die Zulaufbohrungen des Verteilers und axial unterhalb der Verbindungsbohrungen zum Ringraum angeordnet. Insbesondere derart kann auch bei einem hohen Gasgehalt im Produkt, insbesondere bei einem hohen Luftgehalt in Rohmilch, eine besonders gleichmäßige Entkeimung erzielt werden!According to a variant, the ribs are particularly advantageous radially inside the outlet openings from the inlet chamber into the inlet bores of the distributor and axially arranged below the connecting holes to the annulus. Especially like that can even at a high gas content in the product, especially at a high Air content in raw milk, a particularly uniform degermination can be achieved!

Aus der US 5,921,909 ist es zwar bekannt am Austritt der Verteileröffnungen zu den Steigekanälen Rippen anzuordnen (siehe dort Fig. 2),. Die Verteilerkanäle an sich werden durch rippenartige Stege voneinander getrennt. Die Möglichkeit zur Erzeugung erhöhten Unterdrucks mit Rippen zusätzlich zur Verteilerkanalbohrungen und Verbindungsbohrungen zu einem Ringraum zur Erhöhung der Sterilität eines Entkeimungsseparators wurde dort aber nicht erkannt.Although it is known from US 5,921,909 at the outlet of the distribution openings to the Steigekanälen ribs to arrange (see there Fig. 2). The distribution channels themselves are separated by rib-like webs. The possibility of generation increased negative pressure with ribs in addition to the distribution channel bores and Connecting holes to an annulus to increase the sterility of a degermination separator but was not recognized there.

Analoges gilt für die Kammerzentrifugen der DE 36 27 826 C1 und der DE 1 444 977. In letzterer Schrift ist eine obere Fangkammer offenbart, die über Bohrungen mit einem Ringraum in Wirkverbindung steht, der mit Rippen in einzelne Verteilerkanäle unterteilt sein kann. Danach setzen hier die Rippen nicht etwa vor dem Eintritt der Bohrungen für die Verteilerkanäle an sondern sie stellen selbst die Begrenzungswand der Verteilerkanäle dar. Die Fangkammer ist auch nicht oberhalb des unteren Endes des Zulaufrohres angeordnet, so dass in sie kein Produkt eintreten kann. Die Fankammer dient vielmehr dazu, Leckflüssigkeit in die Trommel zurückzuleiten. Die Verhinderung von Kontaminationen steht dabei gerade nicht im Vordergrund der Überlegungen.The same applies to the chamber centrifuges DE 36 27 826 C1 and DE 1 444 977. In the latter document, an upper catching chamber is disclosed which has holes with a Annulus is in operative connection with the ribs in individual distribution channels can be divided. Thereafter, the ribs do not set before the entrance of the Drill holes for the distribution channels but they provide even the boundary wall The distribution chamber is also not above the lower end arranged the inlet pipe, so that no product can enter into it. The fan chamber rather, it serves to recirculate leaking fluid into the drum. The prevention Contaminations are not at the forefront of the considerations.

Bevorzugt sind die Rippen in Drehrichtung nach einer besonders bevorzugten Variante der Erfindung gesehen vor den Austrittsöffnungen und den Verbindungsbohrungen angeordnet. Als besonders vorteilhaft hat es sich ferner herausgestellt, wenn der Zulaufraum eine sich in Einlaufrichtung konisch aufweitende Form aufweist.Preferably, the ribs in the direction of rotation according to a particularly preferred variant the invention seen in front of the outlet openings and the connecting holes arranged. It has also proven to be particularly advantageous if the inlet space has a conically widening shape in the inlet direction.

Die Höhe der Rippen im Einlaufbereich ist vorzugsweise höher als die Höhe der Austrittsöffnungen in den Zulaufbohrungen, beispielsweise um wenigstens das 1,5fache insbesondere mehr als das 2fache, der Höhe der Austrittsöffnungen in die Zulaufbohrungen und entsprechen der des Ringabschnittes vor der Bohrung.The height of the ribs in the inlet region is preferably higher than the height of the outlet openings in the Zulaufbohrungen, for example, at least 1.5 times in particular more than 2 times, the height of the outlet openings in the inlet holes and correspond to that of the ring portion before the bore.

Weitere vorteilhafte Ausgestaltungen sind den übrigen Unteransprüchen zu entnehmen. Further advantageous embodiments can be found in the remaining subclaims.

Figur 1 zeigt eine vereinfachte Darstellung eines Teilbereichs einer Schleudertrommel 1 eines Separators, in der ein Tellerpaket 2 aus einer Vielzahl von Tellern 3 konzentrisch zur Maschinenachse A angeordnet ist. Die Teller 3 weisen eine konische Form auf, sind axial übereinander gestapelt und mittels hier nicht dargestellten Abstandshaltem (Laschen und dgl.) voneinander beabstandet.FIG. 1 shows a simplified illustration of a partial region of a centrifugal drum 1 of a separator in which a disc package 2 of a plurality of plates 3 concentric is arranged to the machine axis A. The plates 3 have a conical shape are stacked axially on top of each other and by means not shown here Abstandshaltem (Tabs and the like.) Spaced apart.

Das Tellerpaket 2 ist an einem Verteilerschaft 4 eines Verteilers 5 gehalten, der an seinem Außenumfang mit radial nach außen vorkragenden Stegen versehen ist (hier nicht zu erkennen), welche am Innenumfang der Teller 3 in diese eingreifen. Das Tellerpaket 2 weist Steigekanäle 6 auf, die aus direkt übereinander liegenden Löchern in den Tellern 3 bestehen und sich über die gesamte Höhe des Tellerpakets 2 erstrecken.The plate package 2 is held on a distributor shaft 4 of a distributor 5, which at its Outer circumference is provided with radially outwardly projecting webs (not here to recognize), which engage on the inner circumference of the plate 3 in this. The plate package 2 has riser channels 6, which consists of directly superimposed holes in the Contain plates 3 and extend over the entire height of the plate package 2.

Ein konzentrisch zur Maschinenachse liegendes Zulaufrohr 7 ermöglicht die Zuleitung eines Schleudergutes hier beispielhaft von oben in die Schleudertrommel 1 sowie dort durch den Verteilerschaft 4 und unterhalb des Tellerpakets 2 im Verteiler 5 ausgebildete Zulaufbohrungen 8 in das Tellerpaket 2, beispielhaft im Bereich des Steigekanals 6 oder an einer anderen Stelle. In der Schleudertrommel 1 erfolgt dann die eigentliche Klärung des zu verarbeitenden Produktes von Feststoffen (z. B. zur Entkeimung) und/oder eine Trennung des Produktes in verschiedene Flüssigkeitsphasen, welche durch Ableitungen 9, 10 auf verschiedenen Durchmessern und Schälscheiben 11, 12 sowie durch hier nicht dargestellte Feststoffausträge aus der Schleudertrommel 1 abgeleitet werden.A concentric to the machine axis lying inlet pipe 7 allows the supply line a centrifuged good example here from above into the centrifugal drum 1 and there formed by the distributor shaft 4 and below the plate package 2 in the distributor 5 Zulaufbohrungen 8 in the plate package 2, for example in the region of the riser channel 6 or elsewhere. In the centrifugal drum 1 is then the actual Clarification of the processed product of solids (eg for sterilization) and / or a separation of the product into different liquid phases, which through leads 9, 10 on different diameters and peeling discs 11, 12th and derived from the centrifugal drum 1 not shown here by solid discharges become.

Von besonderem Interesse ist hier der Aufbau des Zulaufbereiches und dort insbesondere des Verteilers 5 und des Verteilerschaftes 4.Of particular interest here is the structure of the inlet area and there in particular the distributor 5 and the distributor shaft 4.

Ein durch das Zulaufrohr 7 zugeführtes Produkt tritt aus dem Zulaufrohr 7 zunächst in einen sich bei diesem Separator mit vertikaler Maschinen- und Drehachse von oben nach unten konisch aufweitenden Zulaufraum 13 mit innen glatten Flächen im Zentrum des Verteilerschaftes 4 ein, wobei sich der freie untere Austritt des Zulaufrohrs 7 bis unterhalb des oberen Randes des Zulaufraumes 13 erstreckt.A product supplied through the feed pipe 7 first enters from the feed pipe 7 a in this separator with vertical machine and rotary axis from above down conically widening inlet space 13 with inside smooth surfaces in the center of the distributor shaft 4, wherein the free lower outlet of the inlet pipe 7 extends below the upper edge of the inlet space 13.

Der Öffnungswinkel α des Zulaufraumes 13 ist der Größe des Separators und der dazugehörigen Leistung angepasst und kann beispielsweise mehr als 3°, vorzugsweise mehr als 5° betragen.The opening angle α of the inlet space 13 is the size of the separator and the associated Performance adjusted and may, for example, more than 3 °, preferably more than 5 °.

Aus dem Zulaufraum 13 tritt das Produkt radial nach außen (und hier schräg nach unten) durch Austrittsöffnungen 14 aus dem Zulaufraum 13 in die Zulaufbohrungen 8 ein, die innere Abschnitte 23 und sich im Verteiler nach oben erstreckende Abschnitte 24 aufweisen, die unterhalb der Steigekanäle münden.From the inlet space 13, the product passes radially outward (and here obliquely downward) through outlet openings 14 from the inlet chamber 13 into the inlet bores 8 1, the inner portions 23 and upwardly extending portions in the manifold 24, which open below the riser channels.

Vorzugsweise in Drehrichtung (im Uhrzeigersinn; siehe auch Figur 3) ist jeweils direkt hinter jeder der Rippen 16 und radial außerhalb der Rippen eine bohrungsartige Austrittsöffnung 14 aus dem Zulaufraum 13 in die Zulaufbohrungen bzw. -kanäle 8 angeordnet.Preferably in the direction of rotation (clockwise, see also Figure 3) is in each case directly behind each of the ribs 16 and radially outside the ribs a hole-like Outlet opening 14 from the inlet chamber 13 into the inlet bores or channels 8 arranged.

Die Höhe (parallel zur vertikalen Maschinenachse) der Rippen 16 ist größer, beispielsweise um mehr als das 1,5fache größer, als die Höhe der Austrittsöffnungen 14.The height (parallel to the vertical machine axis) of the ribs 16 is greater, for example by more than 1.5 times greater than the height of the outlet openings 14th

Oberhalb der Rippen 16 sind wiederum vorzugsweise in Drehrichtung hinter jeder Rippe 16 und axial oberhalb der Rippen 16 (axial bezogen auf die vertikale Trommelachse M) Verbindungsbohrungen 17 im Verteilerschaft 4 ausgebildet, welche sich von den Austrittsöffnungen 14 des Zulaufraumes 13 parallel zur Umfangswand 18 des Zulaufraumes 13 im Verteilerschaft 4 bis in einen Ringraum 19 erstrecken, welcher im Verteilerschaft 4 oberhalb des unteren Endes des Zulaufrohres 7 und unterhalb der unteren ersten Schälscheibe 11 ausgebildet ist und über einen Ringkanal 20 mit einem weiteren Ringraum 21 verbunden ist, in welchem die erste Schälscheibe 11 angeordnet ist.Above the ribs 16 are again preferably behind each in the direction of rotation Ridge 16 and axially above the ribs 16 (axially relative to the vertical drum axis M) connecting holes 17 formed in the distributor shaft 4, which differs from the outlet openings 14 of the inlet chamber 13 parallel to the peripheral wall 18 of the inlet chamber 13 extend in the distributor shaft 4 into an annular space 19, which in the Distributor shaft 4 above the lower end of the inlet pipe 7 and below the lower first paring disc 11 is formed and via an annular channel 20 with a further annular space 21 is connected, in which the first paring disc 11 is arranged is.

Die Rippen 16 sind innerhalb eines sich radial aufweitenden Ringabschnitts 22 des Ringraums 13 angeordnet, an deren Außenumfang die Eintrittsöffnungen 14 angeordnet sind, wo bereits eine weitere Beschleunigung des Schleudergutes - unterstützt durch die Rippen 16 - erfolgt. Die Rippen 16 verjüngen sich dabei nach einer Variante derart, dass sie die konische Innenkontur des Zulaufraumes in ihrem Bereich nach unten verlängern, was die Verhältnisse im Einlaufbereich weiter optimiert. Die Rippen 16 sind so hoch wie der Ringabschnitt 22 und kann auch so breit sein wie die Verbindungsbohrungen.The ribs 16 are within a radially widening annular portion 22 of the Arranged annular space 13, disposed on the outer circumference of the inlet openings 14 are where already further acceleration of the centrifugal - supported through the ribs 16 - takes place. The ribs 16 are tapered according to a variant such that they the conical inner contour of the Zulaufraumes in their area down extend, which further optimizes the conditions in the inlet area. Ribs 16 are as high as the ring portion 22 and can also be as wide as the connecting holes.

Die Arbeitsweise dieser Anordnung ist wie folgt.The operation of this arrangement is as follows.

Wird zu entkeimende Milch als zu verarbeitendes Produkt durch das Zulaufrohr 7 in den Schleuderraum 1 geführt, weist es zunächst noch die Drehgeschwindigkeit Null und seine axiale Zulaufgeschwindigkeit auf.Is to be sterilized milk as the product to be processed through the inlet pipe 7 in guided the centrifugal space 1, it initially has the rotational speed zero and its axial feed rate.

Sodann wird es im konischen Zulaufraum 13 und dann beim Austritt aus den Austrittsöffnungen 14 an den Rippen 16 im sich radial aufweitenden Ringabschnitts 22 des Ringraums 13 sowie weiter in den Zulaufbohrungen 8 beschleunigt. Dabei entsteht im Ringraum 19 ein Unterdruck, der so groß ist, dass ein Rückvermischen beim Entkeimen der Milch zur Schälscheibenrichtung hin verhindert wird.. Der Unterdruck liegt vorzugsweise bei 0,9 auf 0,6 bar. Auch bei einem hohen Gasgehalt im Produkt, insbesondere bei einem hohen Luftgehalt in Rohmilch erzielt man eine besonders gleichmäßige Entkeimung.Then it is in the conical inlet space 13 and then at the exit from the outlet openings 14 at the ribs 16 in the radially widening annular portion 22 of the Annular space 13 and further accelerated in the inlet holes 8. It arises in the Annulus 19 a negative pressure that is so great that a back mixing during sterilization the milk is prevented from reaching the peeling disk direction. The vacuum is present preferably at 0.9 to 0.6 bar. Even with a high gas content in the product, in particular with a high air content in raw milk one achieves a particularly uniform degermination.

Auch bei Teilentleerungen bleibt dieser vorteilhafte Effekt erhalten.Even with partial emptying this beneficial effect is maintained.

Fig. 4 veranschaulicht die Auslegung eines Entkeimungsseparators zur Entkeimung von Milch mit einer Trommel mit vertikaler Drehachse und mit einem Schlammraum außerhalb des Tellerpakets und einem Kolbenschieber vor Feststoffaustragsöffnungen zum Austragen von Feststoffen wie Keimen.4 illustrates the design of a sterilization separator for sterilization of milk with a drum with vertical axis of rotation and with a mud room outside the plate pack and a spool before Feststoffaustragsöffnungen for discharging solids such as germs.

Der erfindungsgemäße Entkeimer kann beispielhaft ansonsten wie dieser Separator aufgebaut sein, wobei dann allerdings der Zulaufbereich, insbesondere der Verteilerbereich nach Art der Fig. 1 - 3 ausgelegt wird.The degerminator according to the invention may otherwise be exemplified as this separator be constructed, but then the inlet area, in particular the distribution area according to the type of Fig. 1 - 3 is designed.

Vorteilhaft sind wenigstens acht Rippen und Zulaufbohrungen vorgesehen. Die Anzahl der Rippen 16 entspricht damit der Anzahl der Steigekanäle und Austrittsöffnungen. Die Breite der Rippen 16 kann auch der Breite der Verbindungsbohrungen 17 entsprechen. At least eight ribs and inlet bores are advantageously provided. The number the ribs 16 thus corresponds to the number of riser channels and outlet openings. The width of the ribs 16 may also correspond to the width of the connecting bores 17.
