Description

Die Erfindung betrifft ein Verfahren zur Herstellung schwimmender Seife und ein Mischsystem.The invention relates to a method for manufacturing floating soap and a mixing system.

Es ist bekannt, schwimmende Seife dadurch herzustellen, daß in das Seifenstück Schwimmkörper oder luftgefüllte Hohlräume mit oder ohne zusätzliche Aufhängvorrichtung eingebracht werden (DE G 8523621 U1; DE G 8815021.6 U1; DE G 8710724.4 U1; DE 3304748; DE 3307306.6 A1) oder daß am herkömmlichen Seifenstück Schwimmkörper angebracht werden, die die Seife an der Wasseroberfläche halten (DE 3702461.2 A1).It is known to make floating soap by that floating or air-filled in the soap bar Cavities with or without an additional hanging device be introduced (DE G 8523621 U1; DE G 8815021.6 U1; DE G 8710724.4 U1; DE 3304748; DE 3307306.6 A1) or that attached to the conventional soap bar floating body that keep the soap on the surface of the water (DE 3702461.2 A1).

Auch ist es bekannt ("Die Seife und ihre Herstellung", Hempel/Manneck/Schuck/Stein, Verlag für Chemische Industrie H. Ziolkowsky KG Augsburg, 1952, S. 97ff. und S. 958ff.), eine schwimmende Seife durch Einrühren von Luft in eine flüssige bzw. teigige Rohmasse in einem offenen Rührsystem mittels Crutcher herzustellen. Dazu wird die gut abgesetzte Grundseife in einen großen ein Stockwerk über den Crutchern liegenden, mit Dampf indirekt beheizbaren, doppelwandigen Vorratsbehälter gepumpt. Aus dem Vorratsbehälter wird die Grundseite, die eine Temperatur von 77°C bis 82°C besitzen muß, nach den einzelnen Crutchern übergeleitet. Bei höherer Seifentemperatur würde durch eine notwendige längere Rührzeit eine schwammige Seife entstehen, bei zu niedriger Temperatur ergeben sich Schwierigkeiten bei der Erstarrung in Formen. Um die Seife spezifisch leichter als Wasser zu machen, wird ihr Luft durch die Saugwirkung des rückwärts gehenden Schneckengetriebes im Crutcher zugesetzt. Während des Rührens nimmt die Seife eine etwas dickere sahneartige Beschaffenheit an. Nach etwa 12 Minuten wird sich eine aus dem Crutcher entnommene Probe nach kurzem, schnell erfolgendem Erkalten beim Einwerfen in Wasser an dessen Oberfläche halten. Wenn die Seife ungefähr bis zu einem Fünftel des Volumens die Oberfläche des Wassers überragt, ist die Rühraktion abgeschlossen. Ist das noch nicht der Fall, wird der Rührprozeß fortgesetzt und eine neue Probe genommen. Während des Prozesses ist die Temperatur im Vorratsbehälter zu kontrollieren und im angegebenen Bereich zu halten. Vor dem Ablassen der Seife in Formen wird die Parfümierung noch im Crutcher selbst vorgenommen. Der Parfümierung sind enge Grenzen gesetzt, da nur Parfümkompositionen verwendet werden können, die hitzebeständig sind bzw. sich nicht so leicht verflüchtigen. Die zu Seifenblöcken erstarrte Schwimmseife wird in Blockschneidemaschinen in Platten geschnitten, die in Stückeschneidmaschinen in Seifenstücke geschnitten werden. Diese Seifenstücke gelangen in Seifenpressen. Die Zusammensetzung und die Konsistenz der nach diesem Verfahren erzeugten Seife ist also weitgehend in Abhängigkeit vom Zeitablauf dem Zufall überlassen. Das Verfahren ist zeitaufwendig, erfordert wegen der offenen Behälter einen relativ hohen Energieaufwand zum Ersatz der durch Strahlung verlorenen Wärme und ist als Chargenverfahren für eine kontinuierliche Weiterverarbeitung nicht geeignet.It is also known ("The soap and its manufacture", Hempel / Manneck / Schuck / Stein, publishing house for chemical Industrie H. Ziolkowsky KG Augsburg, 1952, pp. 97ff. and P. 958ff.), A floating soap by stirring in Air into a liquid or pasty raw mass in one to produce an open stirring system using a crutcher. To the well-settled basic soap becomes a large one Floor above the crushers with steam indirectly heated, double-walled storage container pumped. The storage container becomes the base side, the must have a temperature of 77 ° C to 82 ° C, according to transferred to individual crutchers. At higher Soap temperature would be necessary due to a longer period Stir a spongy soap to arise at too difficulties arise with the low temperature Solidification in forms. To make the soap specifically lighter To make it as water, its air is absorbed of the reverse worm gear in the crutcher added. The soap takes a little while stirring thicker creamy texture. After about 12 Minutes will take a sample taken from the crutcher after brief, rapid cooling when throwing in hold in water on its surface. If the soap about up to a fifth of the volume of the surface the stirring action is completed. If this is not yet the case, the stirring process continued and taken a new sample. During the Process, the temperature in the reservoir is too high check and keep within the specified range. In front draining the soap in molds will perfume made in the crutcher itself. Perfuming there are narrow limits, since only perfume compositions can be used that are heat-resistant or not evaporate so easily. The soap blocks solidified floating soap is used in block cutting machines Sheets cut in piece cutting machines Soap bars are cut. These soap bars get into soap presses. The composition and the Is consistency of the soap produced by this method so largely depending on the passage of time by chance left. The process is time consuming, required a relatively high one because of the open containers Energy expenditure to replace the radiation lost Heat and is as a batch process for one continuous processing not suitable.

Aus US-A-2 377 424 ist bekannt. Seifenrohstoffe und Gas vor dem verseitungsrozeß miteinander zu mischen und dann zur Reaktion zu bringen, indem passende Fettsäuren, eine Lösung von Natronlauge in passender Konzentration und Luft in den Mischer eingebracht werden. Die sich bildende Seife wird also kontinuierlich mit Luft versetzt. Dabei dienen die Bewegungen des Stabmischers dazu, die Verseifungsreaktion in Gang zu bringen und in Gang zu halten. Die Zuführung der Luft erfolgt bereits zum Zeitpunkt der Verseifung, eine exakte Dosierung des Verhältnisses Seife/Luft ist nicht möglich.It is known from US-A-2 377 424. Soap raw materials and gas to mix with each other before the dilution process and then to react by adding suitable fatty acids, a Appropriate concentration of sodium hydroxide solution and Air is introduced into the mixer. The forming So soap is continuously mixed with air. there the movements of the stick mixer serve to Saponification reaction to get going and going hold. The air is already supplied to the Time of saponification, an exact dosage of the Soap / air ratio is not possible.

Die aufgeheizte Seife und das in diese eingeleitete Gas werden also in dem Mischer bis zur Homogenität gemischt. Es besteht keine Möglichkeit, den Mischvorgang oder die Gaszugabe exakt zu kontrollieren, weshalb es auch nicht möglich ist, verschiedenste Schwimmseifen für beliebig große Chargen herzustellen.Ultimately, US-A-5 364 575 is a system for Produce floating soap, known as the soap is made liquid by heating and with a constant flow rate through a tube is performed, which the melting container with a continuous mixer connects, the liquid Soap before or in the mixer under pressure gas in one is supplied in such a quantity that the soap floats.

In Abhängigkeit vom Massestrom werden aus der Gasbereitstellungseinrichtung 12 durch den Durchflußmengenmesser 5 Luft und/oder Gase wie beispielsweise N2 oder Co2 in die Mischeinheit 6, beispielsweise den Stiftmischer, dosiert. Ebenfalls in Abhängigkeit vom Massestrom werden aus dem zweiten Vorratsbehälter 15 über die Dosiereinrichtung 14 das Zuschlagstoffgemisch und/oder Zuschlagstoffe, beispielsweise Farbstoffe oder Parfüm, mit einem Massestrom von ca. 2-5% in die Mischeinheit 6 dosiert, wobei verschiedene Mischungsverhältnisse von Seife, Gas und Zuschlagstoff eingestellt werden können. In der Mischeinheit 6 werden alle dosierten Stoffe homogen gemischt. Am Ausgang des der Mischeinheit 6 fließt kontinuierlich eine homogen gemischte aufgeschäumte Seifenmasse heraus, in der alle notwendigen Rohstoffe enthalten sind und deren Dichte kleiner als 1 Gramm pro cm3 ist. Die austretende Seifenmasse wird im Temperiersystem 9 auf die entsprechend der anschließenden Weiterbehandlung notwendige Temperatur gebracht und ggf. in der Weiterverarbeitungseinrichtung 13 geformt bzw. portioniert und/oder nochmals temperiert. Die Düse 8 kann so geformt sein, daß bereits ein weiterverarbeitbarer formstabiler Seifenstrang hergestellt wird. Vor Austritt aus dem Wärmetauscher, nach entsprechender Temperierung, durchläuft der plastische Seifenstrang eine Mundlochscheibe, durch die der Rohling seine Form erhält. Anschließend wird der Endlosstrang geschnitten und das Seifenstück in einer herkömmlichen Maschine zu dem gewünschten Stück geformt. Es ist dabei auch möglich, dem Seifenstrang bereits neben der speziellen Form durch die Düse 8 eine andere Struktur zu geben um somit beispielsweise eine mehrfarbige und/oder marmorierte Seife herzustellen. Das kann durch entsprechende Anordnung zweier oder mehrerer Stiftmischer und/oder zweier oder mehrerer Dosiereinheiten 14 mit unterschiedlichen Zuschlagstoffen und die Zusammenführung, Dosierung und Portionierung der verschiedenfarbigen Seifenstränge zu einem homogenen mehrfarbigen Strang erfolgen. Zum anderen können bei mehreren Stiftmischern und/oder Dosiereinheiten sehr variabel schnell eine Charge durch eine andere abgelöst werden.Depending on the mass flow, air and / or gases such as N 2 or Co 2 are metered from the gas supply device 12 through the flow meter 5 into the mixing unit 6, for example the pin mixer. Also depending on the mass flow, the aggregate mixture and / or additives, for example dyes or perfume, are metered from the second storage container 15 via the metering device 14 into the mixing unit 6 with a mass flow of approximately 2-5%, different mixing ratios of soap and gas and aggregate can be adjusted. All metered substances are mixed homogeneously in the mixing unit 6. At the outlet of the mixing unit 6, a homogeneously mixed foamed soap mass flows out, in which all the necessary raw materials are contained and whose density is less than 1 gram per cm 3 . The exiting soap mass is brought to the temperature necessary in accordance with the subsequent further treatment in the temperature control system 9 and, if necessary, shaped or portioned and / or tempered again in the further processing device 13. The nozzle 8 can be shaped in such a way that a shape-retaining soap strand which can be further processed is already produced. Before exiting the heat exchanger, after appropriate tempering, the plastic soap strand passes through a perforated disc through which the blank is given its shape. The continuous strand is then cut and the soap bar is shaped into the desired bar in a conventional machine. It is also possible to give the soap strand a different structure in addition to the special shape through the nozzle 8 in order to produce, for example, a multicolored and / or marbled soap. This can be done by appropriately arranging two or more stick mixers and / or two or more metering units 14 with different additives and combining, metering and portioning the differently colored soap strands into a homogeneous multi-colored strand. On the other hand, in the case of several pen mixers and / or dosing units, one batch can be replaced very quickly by another.

Es ist aber auch möglich, die Seifenmasse vorgeformt in der Weiterverarbeitungseinrichtung 13 weiter zu verarbeiten. So kann sie auf ein Kühlband 10, vorzugsweise ein Stahlband, dosiert werden. Am Ende der Kühlstrecke befindet sich eine Ausstechvorrichtung 16, Figur 2. Sie besteht vorzugsweise aus einer Stechform 17, mit einem Auswerfer 18. Die Stechform 17 ist durch ihren speziellen Aufbau gekennzeichnet; die Formenvielfalt (Umriß) ist grenzenlos. Der Auswerfer 18 ist gleichzeitig ein Prägewerkzeug und ein Stanzwerkzeug. Der Auswerfer 18 wird durch eine Stempelführung 19 in einem Gestell 20 gehalten. Nachdem der Rohling ausgestochen wurde, erhält dieser in der Stanze seine endgültige Form. Aber es ist auch möglich, den Seifenstrang nach dem Austreten aus der Düse 8 in Dauerformen, beispielsweise eine Form 11, zu füllen. Mit den Dauerformen können verschiedene schwierige Formen, die nicht durch Stanzen hergestellt werden können, erzeugt werden. Nach dem Erstarren der Seifenschmelze wird der Anguß geglättet, d.h. abgeschnitten und die Gießform entformt.But it is also possible to preform the soap mass into the further processing device 13 to process. So it can on a cooling belt 10, preferably a steel belt. At the end of There is a cutting device 16 in the cooling section, Figure 2. It preferably consists of a piercing shape 17, with an ejector 18. The piercing shape 17 is through her marked special structure; the variety of shapes (Outline) is limitless. The ejector 18 is at the same time an embossing tool and a punching tool. The ejector 18 is by a stamp guide 19 in a frame 20th held. After the blank has been cut out, get this in the punch its final shape. But it is also possible to remove the soap strand after exiting the Nozzle 8 in permanent forms, for example a form 11 to fill. With the permanent forms can be different difficult shapes that are not made by stamping can be generated. After the solidification of the Soap melt is smoothed, i.e. cut off and the mold removed.

In einem geschlossenem System werden dem flüssigen Seifenstrom bei einer Temperatur von 75 bis 90°C proportional zum Massestrom der flüssigen Seife Gas und Zuschlagstoffe zugeführt. Dabei wird der flüssige Seifenstrom durch rotierende Abscherbewegungen mit zwischen 500000 bis 2000000 Abscherungen pro Minute, beispielsweise durch einen Stiftmischer, mit dem Gas und den Zuschlagstoffen kontinuierlich gemischt. Durch Variierung der Parameter sind das Schaumgewicht, die Schaumfeinheit und die Luftverteilung beispielsweise über die Anzahl der Abscherungen, einstellbar. Der Systemdruck ist so zu wählen, daß er dem Druckverlust in der Weiterverarbeitung entspricht. Die nachfließende Rohseife drückt die gemischte aufgeschäumte Seifenmasse aus dem geschlossenen System kontinuierlich aus dem System, wobei die Seifenmasse gleichzeitig entsprechend dem gewünschten Endprodukt temperiert wird. Das Mischungsverhältnis von Gas zu Seife sollte zwischen 0,5 und 1,0 g/cm3 liegen und der Massestrom der Zuschlagsstoffmischung ca. 2 bis 5% betragen. Zur Erzielung einer glatten Oberfläche des Seifenstranges sollte die Austrittstemperatur ca. 70°C betragen. Die Weiterverarbeitung der austretenden Seifenschmelze erfolgt dadurch, daß sie bandförmig verteilt und gleichmäßig derart temperiert wird, daß sie anschließend ausstechbar ist. Sie kann aber auch derart temperiert werden, daß sie unmittelbar nach dem Austritt geformt, z.B. in Formen gefüllt wird. In a closed system, gas and additives are added to the liquid soap stream at a temperature of 75 to 90 ° C in proportion to the mass flow of the liquid soap. The liquid soap stream is continuously mixed with the gas and the additives by rotating shear movements with between 500,000 and 2,000,000 shearings per minute, for example by a pin mixer. By varying the parameters, the foam weight, the foam fineness and the air distribution can be set, for example, by the number of shears. The system pressure should be selected so that it corresponds to the pressure loss in further processing. The flowing raw soap continuously pushes the mixed, foamed soap mass out of the closed system out of the system, the soap mass being tempered at the same time according to the desired end product. The mixing ratio of gas to soap should be between 0.5 and 1.0 g / cm 3 and the mass flow of the additive mixture should be approx. 2 to 5%. The outlet temperature should be approx. 70 ° C to achieve a smooth surface on the soap bar. The further processing of the emerging soap melt takes place in that it is distributed in the form of a band and tempered uniformly in such a way that it can subsequently be cut out. However, it can also be tempered in such a way that it is shaped, for example filled into molds, immediately after the outlet.

In einem Ausführungsbeispiel des Verfahrens wurde eine Seifenmasse mit einer Dichte > 1 aus 80% Talg und 20% Kokosöl (bezogen aus das Gewicht) und einem Wassergehalt von ca. 25% mit ca. 40 ml Zuschlagsstoffgemisch pro Stunde bei einer Drehzahl von 150 Umdrehungen pro Minute, einer Temperatur von ca. 85°C und einer Seifenfördermenge von ca. 250 g/min gemischt. Die aufgeschäumte Seifenmasse wurde auf ca. 60°C temperiert. Nach Austritt aus der Düse 8 wurde ein definierter flacher Strang auf das Kühlband 10 gelegt, auf ca. 25°C abgekühlt. Anschließend wurden mittels der Stanzeinheit 16 Seifenstücke gestanzt. Das Schaumgewicht der Seife betrug 0,75 bis 0,8 g/cm3.In one embodiment of the method, a soap mass with a density> 1 of 80% tallow and 20% coconut oil (based on the weight) and a water content of approx. 25% with approx. 40 ml aggregate mixture per hour at a speed of 150 revolutions per Minute, a temperature of approx. 85 ° C and a soap flow rate of approx. 250 g / min. The foamed soap mass was heated to about 60 ° C. After emerging from the nozzle 8, a defined flat strand was placed on the cooling belt 10 and cooled to approximately 25 ° C. Then 16 soap bars were punched using the punching unit. The foam weight of the soap was 0.75 to 0.8 g / cm 3 .

In einem anderen Ausführungsbeispiel des Verfahrens wurde eine Seifenmasse mit einer Dichte > 1 aus 75% Talg und 25% Kokosöl (bezogen aus das Gewicht) und einem Wassergehalt von ca. 25% mit ca. 20 ml Zuschlagsstoffgemisch pro Stunde bei einer Drehzahl von 200 Umdrehungen pro Minute, einer Temperatur von ca. 80°C und einer Seifenfördermenge von ca. 200 g/min gemischt. Die aufgeschäumte Seifenmasse wurde auf ca. 70°C temperiert und danach in Formen 11 gefüllt. Das Schaumgewicht der Seife betrug 0,8 bis 0,85 g/cm3. In another embodiment of the method, a soap mass with a density> 1 of 75% tallow and 25% coconut oil (based on the weight) and a water content of approx. 25% with approx. 20 ml aggregate mixture per hour at a speed of 200 revolutions per minute, a temperature of approx. 80 ° C and a soap flow rate of approx. 200 g / min. The foamed soap mass was heated to about 70 ° C and then filled into molds 11. The foam weight of the soap was 0.8 to 0.85 g / cm 3 .
