Derartige Mischverfahren bzw. -vorrichtungen werden beispielsweise in der Futtermittelindustrie angewandt. Sie dienen insbesondere dazu, gasförmige, flüssige, körnige, pulverförmige, mehlige und/oder pastenförmige Stoffe verschiedenster Viskosität miteinander zu vermischen, insbesondere die verschiedensten Arten von Futtermitteln, denen Melasse, Fette usw. zugesetzt werden.Such mixing methods or devices are used, for example, in the animal feed industry applied. They serve, in particular, gaseous, liquid, granular, pulverulent, floury and / or pasty substances of very different viscosity with each other to mix, in particular the most different types of animal feed, which Molasses, fats, etc. are added.
Ein derartiger Mischer ist aus der US-3,415,494 bekannt geworden. Dort ist ein vertikaler Mischer mit einem Gehäuse und einem, mit Paddeln versehenen Mischorgan beschrieben. Das zu vermischende Produkt wird von oben dem Mischer zugegeben und nach dem chargenweise ablaufenden Mischvorgang unten seitlich ausgetragen.Such a mixer has become known from US-3,415,494.

Die DE- A1 41 27 873 offenbart eine Kneteinrichtung für zu knetende Masse, insbesondere Sauerteig mittels eines vertikalen Mischers. Dieser Mischer weist eine Welle mit Rctorstangen auf und an der Behälterinnenwand sind Statorstangen angeordnet, die mit diesen Rotorstangen zusammen wirken. Die Kneteinrichtung weist eine Füllstandshöhenregelung auf und zum Austrag des gekneteten Produktes wird eine Pumpe benötigt. Ein frei fliessender Austrag des Produktes ist offensichtlich nicht möglich.DE-A1 41 27 873 discloses a kneading device for mass to be kneaded, in particular Sourdough by means of a vertical mixer. This mixer has a shaft Ristorstangen on and on the container inner wall stator rods are arranged, the interact with these rotor bars.

Bekannt ist weiterhin ein Durchlaufmischer zum Waschen von Kies u.dgl. gemäss US-PS 3,845,905 mit der Verunreinigungen von Kies vor einem Waschvorgang bzw. Siebvorgang mechanisch abgeschieden werden sollen. Zur Auflockerung des Materials sind im Einzugsbereich Rührpaare vorgesehen und der Durchlauf des Kieses erfolgt ausschliesslich schwerkraftbedingt. Bei einer Mischeinrichtung gemäss US-PS-4,155,657 für Emulsionen, ist in einer Mischkammer ein Rührwerk vertikal angeordnet, dessen obere Rührflügel das eingebrachte Wasser nach unten drücken und der unterste Rührflügel geeignet ist, das Wasser in die Gegenrichtung zu bewegen. Die Mischflügel sind nicht einstellbar, sondern in ihrer Formgebung und Anordnung fix und der Austrag der Emulsionen erfolgt durch eine Öffnung im Deckenbereich der Mischeinrichtung.Also known is a continuous mixer for washing gravel and the like. according to US-PS 3,845,905 with the contamination of gravel before a washing or sieving process should be mechanically separated. To loosen up the material are Stirring pairs are provided in the catchment area and the passage of the gravel is made exclusively gravity. In a mixing device according to US-PS-4,155,657 for emulsions, a stirrer is vertically arranged in a mixing chamber, whose Upper impellers push the introduced water downwards and the bottommost impeller suitable to move the water in the opposite direction. The mixing blades are not adjustable, but fixed in its shape and arrangement and the discharge of the Emulsions take place through an opening in the ceiling area of the mixing device.
Je nach der Art der zu vermischenden Produkte kann bei den bisher bekannten Mischern ein hoher Energiebedarf anfallen. Weiterhin muss mit einem Blockieren der Maschinen gerechnet werden. Im übrigen ist das Einmischen von Flüssigkeiten in den Mischer wegen des verschiedenen Füllgrades nicht optimal möglich.Depending on the nature of the products to be mixed can in the previously known mixers a high energy requirement. Furthermore, having to block the machines be counted. Incidentally, the mixing of liquids in the mixer not optimally possible because of the different degree of filling.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung vorzuschlagen, bei det der Mischvorgang mit geringstem Energiebedarf, einer optimalen Mischung bei Zugabe von Flüssigkeiten verschiedenster Viskosität und ein chargenfreies, d.h. kontinuierliches Mischen erfolgt.The invention is therefore based on the object to propose a device at det the mixing process with the lowest energy consumption, an optimal mix Addition of liquids of various viscosity and a batch-free, i. continuous Mixing done.
Diese Aufgabe wird erfindungsgemäss durch eine Vorrichtung gelöst, bei der der Mischer im Betriebszustand voll gefüllt ist, das Mischprodukt mittels mindestens eines Mischwerkzeuges (mindestens eines davon rückwärtsfördernd) zum einen in Richtung Innenwand des Gehäuses gedrückt wird und zum anderen nach oben gefördert wird, das Mischprodukt aufgrund des Produktdruckes, von der oberhalb der Mischwerkzeuge erforderlichen Produktsäule stetig nach unten gefördert wird und auf diese Art mit den Mischwerkzeugen ein Scherfeld aufgebaut wird (alternativ oder zusätzlich kann der Produktdruck auch über eine (zusätzliche) Druckeinrichtung aufgebaut werden), der Produktfluss, ausgehend von den Einlässen der zu vermischenden Produkte bis zum Auslass des zu vermischenden Produktes kontinuierlich erfolgt, wobei die Ausgangsprodukte ständig in den Mischer eingebracht und der Fluss der Ausgangsprodukte mittels einer am Auslass vorgesehenen Produktaustragseinrichtung dosierbar regelbar ist.This object is achieved by a device in which the mixer is fully filled in the operating state, the mixed product by means of at least one Mixing tool (At least one of them backwards promoting) on the one hand in the direction of the inner wall of the housing is pressed and the other is conveyed upwards, the Mixed product due to the product pressure required by the above mixing tools Product column is steadily pumped down and in this way with the Blending tools a shear field is constructed (alternatively or additionally, the Product pressure can also be built up via an (additional) pressure device), the Product flow, from the inlets of the products to be mixed to the Outlet of the product to be mixed is carried out continuously, the starting materials constantly introduced into the mixer and the flow of the starting materials by means of a product discharge device provided at the outlet can be metered in a controllable manner.
Das mindestens eine Mischwerkzeug ist an einer rotierenden Welle angeordnet. Vorzugsweise ist an dieser auch am Auslass eine Produktaustragseinrichtung angeordnet.The at least one mixing tool is arranged on a rotating shaft. Preferably is arranged at this also at the outlet a product discharge device.
Das Funktionsprinzip des erfindungsgemässen Mischers besteht darin, dass dieser aus dem vollen Produktstrom arbeitet, d.h. der Mischerinnenraum ist immer vollgefüllt. Das zu vermischende Mischprodukt, welches in den Bereich der Mischwerkzeuge gelangt, wird in eine Drehbewegung versetzt und gegen die Innenwand des Mischergehäuses gedrückt, wobei z.B. Paddel des Mischwerkzeuges auf Rückwärtsförderung zumindest teilweise gestellt sind, d.h. entgegengesetzt zum Produktstrom, sodass sich ein Scherfeld aufbaut. Die dampfförmigen, flüssigen bzw. pastösen Zugaben werden oberhalb der ersten (im Produktstrom gesehen von oben), beispielsweise paddelförmig ausgebildeten Mischwerkzeugen oder auf Höhe derselben eingeleitet und mit dem Mischprodukt in Drehrichtung versetzt. Durch die Differenzgeschwindigkeit der einzelnen Partikel, die sich von innen nach aussen verändert, wird der Flüssigkeitsstrom aufgerissen, und die Vermischung setzt ein. Es erfolgt hierbei eine Dichtezunahme in Richtung der Gehäusewand. Begünstigend kann auch der Aufbau eines Scherfeldes durch die Vorwärtsförderung wirken, bzw. durch die Schwerkraft (des Produktes) und die Rückwärtsförderung (der Mischwerkzeuge). The operating principle of the mixer according to the invention is that it is made of the full product stream is working, i. the mixer interior is always full. The mixing product to be mixed, which reaches the area of the mixing tools, is set in a rotational movement and against the inner wall of the mixer housing pressed, e.g. Paddle of the mixing tool on reverse conveying at least are partially set, i. opposite to the product flow, resulting in a shear field builds. The vaporous, liquid or pasty additions are above the first (seen from the top in the product flow), for example paddle-shaped Mixing tools or at the level of the same introduced and mixed with the product offset in the direction of rotation. Due to the differential speed of each particle, the When it changes from the inside to the outside, the liquid flow is torn open, and the Mixing begins. In this case, there is an increase in density in the direction of the housing wall. Favoring can also be the structure of a shear field by the Forward feed, or through the force of gravity (of the product) and the Backward conveying (mixing tools).
Die flüssigen bzw. pastösen Zugaben werden immer in das Produkt geleitet, da der Mischerinnenraum immer gefüllt ist. Mit der angeordneten Produktaustragsvorrichtung wird zugleich der Durchsatz geregelt. Somit ist ein kontinuierlicher, d.h. dosierbarer Mischprozess gewährleistet. Es wird dadurch eine Selbstdosierung ermöglicht. Die Zugabe von Dampf kann bei geschlossenem Auslaufschieber erfolgen. Der Mischer ist dadurch unmittelbar an einer Futterwürfelpresse oder an einem Expander anschliessbar. Der Produktabschluss nach oben wirkt sich positiv auf die Temperatur aus. Dies ermöglicht beispielsweise bei Anwendung mit Mehl hohe Temperaturen mit geringer Feuchtigkeit. Der obere Teil des Mischerinnenraumes bleibt immer gefüllt. Ein weiterer, damit verbundener Vorteil besteht darin, dass eine Verschmutzung des Einlaufteiles ausgeschlossen ist.The liquid or pasty additions are always passed into the product, as the mixer interior always filled. With the arranged product discharge device At the same time the throughput is regulated. Thus, a continuous, i. dosable Ensures mixing process. It is thereby possible a self-dosing. The addition Steam can be done with the spout closed. The mixer is This can be connected directly to a feed cube press or to an expander. The product closure upwards has a positive effect on the temperature. This allows for example when used with flour high temperatures with less Humidity. The upper part of the mixer interior is always filled. Another, associated advantage is that a contamination of the inlet part is excluded.
Der 100%ige Füllgrad ermöglicht eine Nutzung von Scherkräften. Zugleich wirkt der Produktdruck von der, oberhalb der Mischwerkzeuge erforderlichen Produktsäule. Altemativ oder zusätzlich kann der Produktdruck auch über eine zusätzliche Druckeinrichtung aufgebaut werden. Die Förderung des Produktes kann auch durch die Schwerkraft bei rückwärts fördernden Mischwerkzeugen, z.B. Paddeln, erfolgen.The 100% degree of filling allows the use of shear forces. At the same time, it works Product pressure from the product column required above the mixing tools. Alternatively or additionally, the product pressure may also be via an additional printing device being constructed. The promotion of the product can also be by gravity in reverse conveying mixing tools, e.g. Paddling, done.
Der Mischer zeichnet sich durch eine sehr einfache Konstruktion aus. Der Mischer ist sehr leicht zu warten. Er kann innerhalb von wenigen Sekunden geöffnet werden. Eine Isolation oder eine Beheizung ist dadurch sehr einfach realisierbar. Im übrigen arbeitet der Mischer vibrationsfrei.The mixer is characterized by a very simple construction. The mixer is very easy to wait. It can be opened within a few seconds. A Isolation or heating is thus very easy to implement. Otherwise works the mixer is vibration-free.
Die mit der Vorrichtung verbundenen Vorteile liegen insbesondere darin, dass nach dem Durchlaufprinzip gearbeitet wird und der Füllgrad immer gleich ist. Dies ermöglicht eine bessere Einmischung der Flüssigkeiten bzw. der viskosen Pasten in das trockene Produkt. Der Mischer wird weniger verschmutzt, was die Reinigung sehr vereinfacht und eine Temperaturerfassung ist genauer. Ein wesentlicher Vorteil der Vorrichtung besteht darin, dass die zu vermischenden Produkte durch die Zugabe von Dampf hygienisiert werden können. The advantages associated with the device are in particular that after the flow principle is used and the degree of filling is always the same. this makes possible a better mixing of the liquids or the viscous pastes in the dry Product. The mixer is less polluted, which greatly simplifies cleaning and temperature detection is more accurate. An essential advantage of the device is that the products to be mixed can be sanitized by the addition of steam.
Ein Blockieren der Maschine ist unmöglich. Auch ist der Energiebedarf gegenüber Mischern des Standes der Technik stark reduziert. Weiterhin sind erhebliche Vorteile in der Anwendung des erfindungsgemässen Mischers bei Futterwürfelpressen, Expandern oder Batchmischem gegeben.Blocking the machine is impossible. Also, the energy needs compared to mixers of the prior art greatly reduced. Furthermore, considerable advantages in the application of the inventive mixer given in feed cube presses, expanders or batch mixers.
Eine Speisung des Mischers aus mehreren Silozellen ist möglich. Die Futterwürfelpresse bzw. der Expander kann lastabhängig gesteuert werden. Wegen der genauen Temperaturermittlung im Mischer kann die Futterwürfelpresse bzw. der Expander mit vorgegebenen Sollwert-Temperaturen angefahren werden. Ein Dosieren mit Frequenzsteuerung entfällt. Weiterhin entfallen bei Anwendung dieses erfindungsgemässen Mischers Verklebungen im Bereich des Einlaufes der Futterwürfelpressen bzw. der Expander. Falls es zum Futterwürfelpressenaufstau kommen sollte, kann ohne Mischerentleerung direkt weitergefahren werden. Insbesondere bei Zugabe von Melasse, wobei sogar kalte Melasse möglich ist, treten wenig Verklebungen bzw. Verklumpungen auf.A feed of the mixer from several silo cells is possible. The feed cube press or the expander can be controlled load-dependent. Because of the exact Temperature determination in the mixer, the feed cube press or the expander with be approached predetermined setpoint temperatures. A dosing with frequency control eliminated. Furthermore omitted when using this inventive Mischers bonding in the area of the inlet of the feed die presses or the Expander. If it should come to the Futterwürfelpressenaufstau, without mixer emptying continue driving straight away. Especially with the addition of molasses, although even cold molasses is possible, little sticking or clumping occur on.
Weiterhin ist auch die Beigabe von Flüssigkeiten nach dem Mischer möglich. Es ist keine Dosierung erforderlich. Eine Richtungsänderung des Mischproduktes nach dem Mischer, etwa von vertikaler in horizontaler Richtung, ist problemlos möglich. Eine Entmischung findet beim Auslaufen nicht statt. Eine Knollenbildung wird vermieden. Im übrigen sind alle Anwendungen des erfindungsgemässen Mischers denkbar, wie z.B. die Verwendung als Dosierer, die Beigabe des Mischproduktes in warmes Mehl, sowie die Zugabe von Fett bzw. Flüssigkeiten auf Pellets nach einer Futterwürfelpresse.Furthermore, the addition of liquids after the mixer is possible. It is not Dosage required. A change of direction of the mixed product after the mixer, from vertical to horizontal, is easily possible. A demix does not take place when leaving. Tuber formation is avoided. Furthermore all applications of the mixer according to the invention are conceivable, e.g. the Use as a dosing, the addition of the mixed product in warm flour, and the Adding fat or liquids to pellets after a feed cube press.
