Definitions
- the invention relates to a process for producing free-flowing detergent and cleaning agent granules and / or partial granules, in which aqueous alkyl and / or alkenyl oligoglycoside pastes are dried in a turbine dryer with rotating internals in the presence of surfactants and / or further detergent and cleaning agent ingredients granulated at the same time.
- Powdered detergents and cleaning agents are usually produced by spray drying.
- an aqueous slurry (“slurry") of the ingredients, for example surfactants, builders and adjusting agents, is pumped into the spray tower and sprayed through nozzles located in the top of the tower. Rising air with a temperature of 250 to 300 ° C dries the slurry and evaporates the adhering water, so that at the outlet of the tower a practically water-free granular or powdery Product is received. Details of this process are described, for example, in ROEMPP Chemie Lexikon, Thieme Verlag, Stuttgart, Vol. V, 1992 under the keyword “spray drying”.
- European patent application EP-A 0 411 477 relates to a process for spray drying alkyl glucosides at 160 to 170 ° C., in which aqueous solutions with a very low surfactant content are used and the drying is carried out in the presence of a very large amount of carrier salt.
- the object of the invention was therefore to develop a new process for the production of detergent and cleaning agent granules and / or partial granules which is free from the disadvantages described.
- the invention relates to a process for producing free-flowing detergent and cleaning agent granules and / or partial granules, which is characterized in that aqueous alkyl and / or alkenyl oligoglycoside pastes in the presence of anionic and / or nonionic surfactants and / or usual detergent and cleaning agent ingredients in a turbine dryer with rotating internals dewatered to a residual water content of 0.1 to 5 wt .-% and granulated at the same time.

Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung rieselfähiger Wasch- und Reinigungsmittelgranulate und/oder -teilgranulate, bei dem man wäßrige Alkyl-und/oder Alkenyloligoglykosid-Pasten in Gegenwart von Tensiden und/oder weiteren Wasch- und Reinigungsmittelinhaltsstoffen in einem Turbinentrockner mit rotierenden Einbauten trocknet und gleichzeitig granuliert.The invention relates to a process for producing free-flowing detergent and cleaning agent granules and / or partial granules, in which aqueous alkyl and / or alkenyl oligoglycoside pastes are dried in a turbine dryer with rotating internals in the presence of surfactants and / or further detergent and cleaning agent ingredients granulated at the same time.
Die Herstellung von pulverförmigen Wasch- und Reinigungsmitteln mitteln erfolgt üblicherweise durch Sprühtrocknung. Hierbei wird eine wäßrige Aufschlämmung ("Slurry") der Inhaltsstoffe, beispielsweise Tenside, Builder und Stellmittel, über Pumpen in den Sprühturm befördert und über im Kopf des Turms befindliche Düsen versprüht. Aufsteigende Luft mit einer Temperatur von 250 bis 300°C trocknet den Slurry und verdampft das anhaftende Wasser, so daß am Auslaß des Turms ein praktisch wasserfreies granuliertes bzw. pulverförmiges Produkt erhalten wird. Einzelheiten dieses Verfahrens sind beispielsweise in ROEMPP Chemie Lexikon, Thieme Verlag, Stuttgart, Bd.V, 1992 unter dem Stichwort "Sprühtrocknung" beschrieben.Powdered detergents and cleaning agents are usually produced by spray drying. Here, an aqueous slurry ("slurry") of the ingredients, for example surfactants, builders and adjusting agents, is pumped into the spray tower and sprayed through nozzles located in the top of the tower. Rising air with a temperature of 250 to 300 ° C dries the slurry and evaporates the adhering water, so that at the outlet of the tower a practically water-free granular or powdery Product is received. Details of this process are described, for example, in ROEMPP Chemie Lexikon, Thieme Verlag, Stuttgart, Vol. V, 1992 under the keyword "spray drying".
Aus der Internationalen Patentanmeldung WO 92/01036 ist ein Verfahren zur Herstellung von lagerstabilen Tensidgranulaten bekannt, bei dem man wäßrige Tensidmischungen, die noch einen Anteil an weiteren Waschmittelinhaltsstoffen aufweisen können, zunächst granuliert und anschließend in der Wirbelschicht zumindest anteilig von Wasser befreit. Beschrieben wird beispielsweise die Herstellung von Alkylglucosidgranulaten, bei der man eine 55 Gew.-%ige Tensidpaste zusammen mit Soda zu einem Granulat verarbeitet. Auf das Granulat wird im Mischer weitere Tensidpaste aufgetragen und das Zwischenprodukt anschließend in der Wirbelschicht getrocknet.From international patent application WO 92/01036 a process for the production of storage-stable surfactant granules is known, in which aqueous surfactant mixtures, which may also have a proportion of further detergent ingredients, are first granulated and then at least partially freed of water in the fluidized bed. The production of alkyl glucoside granules is described, for example, in which a 55% by weight surfactant paste is processed together with soda to form a granulate. Further surfactant paste is applied to the granules in the mixer and the intermediate product is then dried in the fluidized bed.
Gegenstand der Europäischen Patentanmeldung EP-A 0 411 477 ist ein Verfahren zur Sprühtrocknung von Alkylglucosiden bei 160 bis 170°C, bei der man wäßrige Lösungen mit einem sehr niedrigen Tensidgehalt einsetzt und die Trocknung in Gegenwart einer sehr großen Menge Trägersalz durchführt.European patent application EP-A 0 411 477 relates to a process for spray drying alkyl glucosides at 160 to 170 ° C., in which aqueous solutions with a very low surfactant content are used and the drying is carried out in the presence of a very large amount of carrier salt.
Schließlich wird in der Europäischen Patentanmeldung EP-A 0 340 966 die Verwendung von Turbinentrocknern für die Herstellung von festen Alkylbenzolsulfonat/Bentonit-Mischungen beschrieben.Finally, the use of turbine dryers for the production of solid alkylbenzenesulfonate / bentonite mixtures is described in European patent application EP-A 0 340 966 .
Für die Herstellung von Pulverprodukten, die als Tensigkomponente - allein oder in Mischung mit anderen oberflächenaktiven Substanzen - Alkyl- und/oder Alkenyloligoglykoside enthalten, ist dieses Verfahren jedoch wenig geeignet, da die erforderlichen hohen Temperaturen im Sprühturm zu einer teilweisen Zersetzung des Glucosidkörpers führen können. Die Folge sind Granulate bzw. Teilgranulate, die eine schlechte Farbqualität bzw. unbefriedigende anwendungstechnische Eigenschaften aufweisen. Unter Teilgranulaten sind in diesem Zusammenhang Vorprodukte zu zu verstehen, aus denen unter Zusatz von geeigneten Wirkstoffen Wasch- und Reinigungsmittel durch Mischprozesse hergestellt werden können.However, this process is not very suitable for the production of powder products which contain alkyl and / or alkenyl oligoglycosides as the surfactant component, alone or in a mixture with other surface-active substances, since the high temperatures required in the spray tower can lead to partial decomposition of the glucoside body. The result is granules or partial granules that have poor color quality or unsatisfactory application properties. In this context, partial granules are to be understood as preliminary products from which washing agents and cleaning agents can be produced by mixing processes with the addition of suitable active ingredients.
Die Aufgabe der Erfindung bestand somit darin, ein neues Verfahren zur Herstellung von Wasch- und Reinigungsmittelgranulaten und/oder -teilgranulaten zu entwickeln, das frei von den geschilderten Nachteilen ist.The object of the invention was therefore to develop a new process for the production of detergent and cleaning agent granules and / or partial granules which is free from the disadvantages described.
Gegenstand der Erfindung ist ein Verfahren zur Herstellung rieselfähiger Wasch- und Reinigungsmittelgranulate und/oder -teilgranulate, das sich dadurch auszeichnet, daß man wäßrige Alkyl- und/oder Alkenyloligoglykosid-Pasten in Gegenwart von anionischen und/oder nichtionischen Tensiden und/oder üblichen Wasch- und Reinigungsmittelinhaltsstoffen in einem Turbinentrockner mit rotierenden Einbauten bis auf einen Restwassergehalt von 0,1 bis 5 Gew.-% entwässert und gleichzeitig granuliert.The invention relates to a process for producing free-flowing detergent and cleaning agent granules and / or partial granules, which is characterized in that aqueous alkyl and / or alkenyl oligoglycoside pastes in the presence of anionic and / or nonionic surfactants and / or usual detergent and cleaning agent ingredients in a turbine dryer with rotating internals dewatered to a residual water content of 0.1 to 5 wt .-% and granulated at the same time.
Überraschenderweise wurde gefunden, daß sich hellfarbige und praktisch wasserfreie Wasch- und Reinigungsmittelgranulate und/oder -teilgranulate erhalten lassen, wenn man die Trocknung und Granulierung von Alkyl- und/oder Alkenyloligoglykosid-Pasten in Gegenwart von Tensiden und/ oder anderen typischen Inhaltsstoffen in einem Turbinentrockner durchführt. Die Produkte sind lagerstabil und zeichnen sich zudem durch eine enge Korngrößenverteilung aus.Surprisingly, it was found that light-colored and practically water-free detergent and cleaning agent granules and / or partial granules can be obtained if the drying and granulation of alkyl and / or alkenyl oligoglycoside pastes in the presence of surfactants and / or other typical ingredients in a turbine dryer carries out. The products are stable in storage and are also characterized by a narrow grain size distribution.

Das Verhältnis der einzelnen Komponenten untereinander ist unkritisch, solange sichergestellt ist, daß die Einsatzstoffe problemlos, d. h. unter Zuhilfenahme üblicher Pumpen oder anderer Fördermittel, in den Turbinenmischer eindosiert werden können. Im Hinblick auf die vorliegende Aufgabenstellung sind solche Mischungen bevorzugt, die nach Trockung und Granulierung Wasch- und Reinigungsmittelgranulate und/oder - teilgranulate mit einem Gehalt an Alkyl- und/oder Alkenyloligoglykosiden von 2 bis 90, vorzugsweise 5 bis 70 Gew.-%-bezogen auf die Granulate - ergeben.The ratio of the individual components to one another is not critical as long as it is ensured that the feed materials can be metered into the turbine mixer without any problems, ie with the aid of conventional pumps or other conveying means.

Unter Turbinentrocknern sind zylindrische Trockenapparaturen, vorzugsweise in horizontaler Bauweise zu verstehen, in denen rotierende Einbauten mit hoher Drehzahl für eine feine Verteilung des Trockengutes sorgen. In einer bevorzugten Ausführungsform handelt es sich bei diesen Einbauten beispielsweise um Flügel, Schaufeln oder Paddeln, die auf einer rotierenden Welle (Umfangsgeschwindigkeit 5 bis 25 m/s, vorzugsweise 10 bis 20 m/s) angebracht sind. Die eigentliche Trocknung kann bei Wandtemperaturen von 100 bis 180°C und Gasphasentemperaturen von 150 bis 220°C vorzugsweise in Gegenwart von Luft, Inertgasen wie beispielsweise Stickstoff oder überhitztem Wasserdampf stattfinden, wobei der Wärmeübergang durch Konvektion sowie die beheizte Wandung des Trockners erfolgt. Im Hinblick auf die Herstellung der erfindungsgemäßen Wasch- und Reinigungsmittelgranulate und/oder -teilgranulate sich eine Temperatur der Gasphase von 150 bis 220°C als optimal erwiesen. Die Abtrennung des Trokkengutes kann beispielsweise mit Hilfe eines Zyklons und/oder eines Schlauchfilters erfolgen. Turbine dryers are to be understood as cylindrical drying apparatuses, preferably in a horizontal construction, in which rotating internals at high speed ensure a fine distribution of the dry material. In a preferred embodiment, these internals are, for example, wings, blades or paddles which are mounted on a rotating shaft (peripheral speed 5 to 25 m / s, preferably 10 to 20 m / s). The actual drying can take place at wall temperatures of 100 to 180 ° C and gas phase temperatures of 150 to 220 ° C, preferably in the presence of air, inert gases such as nitrogen or superheated steam, whereby the heat transfer takes place by convection and the heated wall of the dryer. With regard to the production of the detergent and cleaning agent granules and / or partial granules according to the invention, a temperature of the gas phase of 150 to 220 ° C. has proven to be optimal. The dry goods can be separated off, for example, using a cyclone and / or a bag filter.
Da die aufgeheizte Luft bzw. das aufgeheizte Inertgas gleichzeitig mit dem zu trocknenden feuchten Produkt in den Trockner eingebracht wird, findet eine augenblickliche Verdampfung des Wassers statt. Aufgrund der hohen Verdampfungswärme von Wasser führt dies zu einem temperaturstabilisierenden Effekt, so daß die Trocknung auch bei hohen Temperaturen erfolgen kann, ohne daß es zu einer Zersetzung temperaturlabiler Produkte kommt.Since the heated air or the heated inert gas is introduced into the dryer at the same time as the moist product to be dried, an instantaneous evaporation of the water takes place. Due to the high heat of vaporization of water, this leads to a temperature-stabilizing effect, so that drying takes place even at high temperatures can without decomposing temperature-sensitive products.
Besondere Merkmale der erfindungsgemäß einzusetzenden Turbinentrockner sind somit die kurze Verweilzeit, das enge Verweilzeitspektrum und die hohe Temperaturstabilisierung, die eine möglichst schonende Behandlung des Trockengutes, gerade im Hinblick auf Zusammensetzung und Farbe, sicherstellen.Special features of the turbine dryers to be used according to the invention are thus the short residence time, the narrow residence time spectrum and the high temperature stabilization, which ensure that the dry material is treated as gently as possible, particularly with regard to its composition and color.
Die nach dem erfindungsgemäßen Verfahren erhältlichen Wasch-und Reinigungsmittelgranulate und/oder -teilgranulate weisen einen Restwassergehalt von 0,1 bis 5 Gew.-% und eine vorteilhaft enge Korngrößenverteilung auf. Sie eignen sich beispielsweise zur Herstellung von Pulverwaschmitteln, in denen sie in Konzentrationen von 10 bis 100 Gew.-% - bezogen auf die Mittel - enthalten sein können.The detergent and cleaning agent granules and / or partial granules obtainable by the process according to the invention have a residual water content of 0.1 to 5% by weight and an advantageously narrow particle size distribution. They are suitable, for example, for producing powder detergents, in which they can be present in concentrations of 10 to 100% by weight, based on the detergents.
