Description

Vorrichtung zur Entfernung des Lösungsmittels aus lösungsmittelfeuchten Schroten Zur Entfernung des Lösungsmittels aus z. B. henzinfeuchten Schroten, wie Extraktionsrückständen von Sojabohnen usw., verwendet man heute Rührwerksapparate, sogenannte Toaster, in denen gleichzeitig eine Kochung des Schrotes mit entsprechender Umwandlung des Proteins stattfindet. Solche Einrichtungen, die z. B. in den USA.-Patentschriften 2585 793 und 2695 459 sowie in den deutschen Gebrauchsmustern 1 752525 und 1 747050 beschrieben sind, bestehen aus innerhalb eines Gehäuses untereinander angeordneten Abteilen, die das zu behandelude Schrot von oben nach unten Idurchläuft. In dem obersten Teil wird Direktdampf eingeführt, um das Lösungsmittel zu verdampfen und einen bestimmten Feuchtigkeitsgehalt des Gutes zu erzielen, während in den - darunterliegenden Abteilungen unter indirekter Dampfbeheizung eine Kochung und Toastung des Gutes stattfindet. Device for removing the solvent from solvent-moist Grist To remove the solvent from z. B. henzin-dampened meal, such as Extraction residues from soybeans etc., agitators are used today, so-called toasters, in which simultaneously a cooking of the meal with appropriate Conversion of the protein takes place. Such facilities that z. B. U.S. Patents 2585 793 and 2695 459 as well as in the German utility models 1 752525 and 1 747050 are described, consist of arranged one below the other within a housing Compartments that the shot to be treated passes through from top to bottom. By doing At the top, live steam is introduced to evaporate the solvent and to achieve a certain moisture content of the goods, while in the - underlying Departments cook and toast the goods under indirect steam heating takes place.

Beilm Betrieb dieser Vorrichtungen hat es sich nun gezeigt, daß vielfach Schrotteilchen durch den abziehenden Brüdenstrom, d. h. das Lösungsmittel-Wasserdampf-Gemisch, hochgerissen werden und mit den Brüden in die Kondensationsanlage gelangen. During the operation of these devices it has now been found that many times Shot particles by the withdrawing vapor stream, d. H. the solvent-steam mixture, are torn up and get into the condensation system with the vapors.

Dies hat den Nachteil zur Folge, Idaß die Konfdensationseinrichtungen durch die darin abgeschiedenen Schrotteilchen verunreinigt werden.This has the disadvantage that the condensation devices be contaminated by the shot particles deposited therein.

Diese und andere Nachteile werden erfindungsgemäß bei einer Vorrichtung zur Entfernung des Lösungsmittels aus lösungsmittelfeuchten Schroten durch Einleiten von Dampf, bestehend aus einem senkrecht stehenden Zylinder mit einem Rührwerk und untereinanlder angeordneten Abteilen, aus dem die Brüden oben um etwa 90" versetzt zur Apparatachse herausgeführt werden, dadurch vermieden, daß innerhalb des senkrecht oder etwa senkrecht zur Achse des Apparates geführten Brüdenabzugsrohres eine Speiseschnecke am Boden des Rohres vorgesehen ist. These and other disadvantages become apparent in an apparatus according to the invention for removing the solvent from solvent-moist meal by introducing it of steam, consisting of a vertical cylinder with an agitator and Compartments arranged below one another, from which the vapors are offset by about 90 "at the top are led out to the apparatus axis, thereby avoiding that within the perpendicular or a vapor discharge pipe running approximately perpendicular to the axis of the apparatus, a feed screw is provided at the bottom of the pipe.

Die Anordnung der Speiseschnecke am Boden des Brüdenabzugsrohres bringt den Vorteil Imit sich, daß der dort abgesetzte Staub wieder ins Produkt zurückgeführt wird. Falls diese Schnecke nicht angebracht wird, wird das Rohr in relativ kurzler Zeit vollständig mit abgesetztem Staub gefüllt, und ein ordnungsgemäßer Betrieb der vorgeschlagenen Brüdenabführung ist dann nicht mehr möglich. Rs ist daher erforderlich, die kontinuierliche Rückführung des abgesetzten Staubes vermittels Ider erwähnten Speiseschnecke vorzunehmen. Die Speiseschnecke selber fördert auch das zu entbenzinierende Gut, und es wird, um den Staub nicht erneut aufzuwirbeln, das frische Schrot mit dem abgeschiedenen Staub wieder verbunden und gemeinsam dann zur eigentlichen Entbenzinierung weitergeleitet. The arrangement of the feed screw at the bottom of the vapor discharge pipe has the advantage that the dust deposited there is fed back into the product will. If this screw is not attached, the pipe will be relatively shorter Time completely filled with settled dust, and proper operation the proposed vapor removal is then no longer possible. Rs is therefore required the continuous recycling of the deposited dust by means of those mentioned To make the feed screw. The food snail itself also promotes that which is to be degassed Good, and so as not to stir up the dust again, the fresh grist is included reconnected to the separated dust and then together for the actual degassing forwarded.

Es hat sich ferner als zweckmäßig erwiesen, die Welle der Schnecke hohl und heizbar auszubilden. It has also proven to be useful that the Shaft of the snail to be hollow and heatable.

Hierdurch wird der weitere Vorzug erreicht, daß das Ankleben von Material infolge Kondensation der umgebenden Brüden verhindert wird. Durch Kot'den sation der Brüden könnten nämlich sonst Verklebungen durch Staub auftreten, die dazu führen würden, daß die Schnecke so weit mit Material verklebt wird, daß eine Pörderung nicht mehr möglich ist.This has the further advantage that the sticking of material due to condensation of the surrounding vapors is prevented. Through Kot'den sation of the vapors could otherwise stick together due to dust, which leads to this would that the screw is stuck so far with material that a promotion is no longer possible.

Die aus dem Brüdenabzugsrohr austreten'den vorgereinigten Brüden können sodann über Brüden waschanlagen beliebiger Konstruktion der Kondensationsanlage zugeleitet werden. The pre-cleaned vapors emerging from the vapor discharge pipe can then use vapor washing systems of any design of the condensation system be forwarded.

Zur weiteren Erläuterung,der Erfindung Idiene die Zeichnung, die eine Ausführungsform beispielsweise und schematisch wiedergibt. For further explanation, the invention Idiene the drawing, the shows an embodiment example and schematically.

In der Zeichnung ist mit 1 der Toaster bezeichnet, der innerhalb eines Gehäuses mehrere untereinander angeordnete Abteile2 besitzt, in denen die Behandlung des lösungsmittelfeuchten Schrotes durchgeführt wird. In the drawing, 1 denotes the toaster, the inside of a housing has several compartments 2 arranged one below the other, in which the Treatment of the solvent-dampened meal is carried out.

Aus Idem -i-m Oberteil des Toasters 1 befindlichen Schrotbett 3 entweichen die Brüden in Richtung der Pfeile4, d. h. parallel zur Achse des Toasters. Die Brüden werden durch den Toasterdeckel 5 umgeleitet, und zwar um etwa 900 zur Toasterachse, so daß sie durch -das Brüdenabzugsrohr 6 senkrecht zu ihrer bisherigen Strömungsrichtung aus dem Toaster austreten. In dem Rohr 6 ist erfindungsgemäß die Speiseschnecke 7 angeordnet. Infolge der Ablenkung des Brüdenstromes scheiden sich die darin befindlichen mitgerissenen Schrotteilchen schon teilweise in der Toasterhaube und weiter in dem Rohr 6 ab. Sie werden mit dem durch die Speiseschnecke 7 zugeführten frischen, lösungsmittelfeuchten Schrot vermischt und gelangen zusammen mit Idiesem wieder in den Toaster 1. Aus der Brudenafbzugsöffnung 8 treten somit auf die geschilderte Weise vorgereinigte Brüden aus und gelangen in die nicht gezeichneten weiteren Brüdenwascheinrichtungen. Durch den Stutzen 9 tritt das frische, lösungsmittelfeuchte Schrot ein und wird innerhalb des Rohres 6 durch die Speiseschnecke 7 gefördert. Die Welle der Schnecke 7 kann hohl ausgebildet und heizbar serin. Es ist jedoch auch möglich, das Brüdenabzugsrohr ganz oder teilweise mit einem Heizdoppelmantel zu umgeben. Escape from the Idem -i-m upper part of the toaster 1 is the bed of grist 3 the vapors in the direction of the arrows 4, d. H. parallel to the axis of the toaster. The vapors are diverted through the toaster lid 5, namely by about 900 to the toaster axis, so that they through the vapor discharge pipe 6 perpendicular to their previous flow direction emerge from the toaster. According to the invention, the feed screw is in the pipe 6 7 arranged. As a result of the deflection of the vapor stream, those located in it separate entrained shot particles already partly in the toaster hood and further in that Pipe 6 off. They become moist with the fresh, solvent-moist fed by the feed screw 7 Shot mixed and get back into the with this Toaster 1. From the Brudenafbzugöffnung 8 thus step in the manner described Pre-cleaned vapors from and get into the not shown other vapor scrubbing devices. The fresh, solvent-moist meal enters through the nozzle 9 and becomes conveyed within the pipe 6 by the feed screw 7. The shaft of the snail 7 can be hollow and heatable serine. However, it is also possible to use the vapor discharge pipe to be completely or partially surrounded by a heating jacket.
