Abstract

Water-soluble detergents and enzymes are used for mechanically cleaning textiles or crockery. According to the invention, enzymes with a catalytic effect on typical stains are added to the washing or cleaning process, only for as long as their catalytic effect is desired. This avoids superfluous removal of the enzymes that have been used in a washing or cleaning process.

Description

Die Erfindung geht aus von einem Verfahren zum maschinelten Reinigen von Textilien oder festen Gegenständen, wie Geschirr, unter Anwendung von in Wasser löslichen Wasch und/oder Reinigungsmitteln und Enzymen.The invention is based on a process for the automated cleaning of textiles or solid objects, such as dishes, using water-soluble detergents and / or cleaning agents and enzymes.

Bisher übliche Verfahren der vorstehenden Art ( DE 43 24 202 A1 ) verwenden Enzyme als Reinigungsverstärker während der Dauer der Einwirkung von beispielsweise alkalischen Reinigungsmitteln. Enzyme werden bei modernen Waschsystemen beispielsweise in Form eines Pulvers dem Waschprozeß zugegeben. Je nach Verschmutzungsart sind unterschiedliche Enzyme erforderlich, was eine entsprechende Bevorratung erforderlich macht und den Auswahl- bzw. Dosiervorgang aufwendig gestaltet. Während des Waschprozesses werden nicht nur Kohlehydrate oder Eiweiße aufgelöst bzw. abgebaut; durch die Anwesenheit der alkalischen Reinigungsmittel werden die Enzyme auch selbst angegriffen und entweder abgebaut oder zumindest unwirksam. Schlußendlich werden auch nicht zerstörte Enzyme nach jedem Waschvorgang mit der Flotte ausgespült und müssen daher ständig neu zugegeben werden. Weiterer relevanter Stand der Technik ist in den Dokumenten US4745021 , US 4756844 , GB2254857 und GB2339579 , angegeben.Hitherto conventional methods of the above type ( DE 43 24 202 A1 ) use enzymes as cleaning enhancers during the period of action of, for example, alkaline detergents. Enzymes are added to the washing process in modern washing systems, for example in the form of a powder. Depending on the type of contamination, different enzymes are required, which requires appropriate storage and makes the selection or dosing process expensive. During the washing process not only carbohydrates or proteins are dissolved or broken down; The presence of alkaline detergents also attacks the enzymes themselves and either degrades them or at least renders them ineffective. Finally, undamaged enzymes are rinsed out with the liquor after each wash and must therefore be constantly added again. Further relevant prior art is in the documents US4745021 . US 4756844 . GB2254857 and GB2339579 , stated.

Der Erfindung liegt die Aufgabe zugrunde, die Auflösung bzw. das Unwirksamwerden der Enzyme zu verhindern und das Ausspülen noch brauchbarer Enzyme zu vermeiden.The invention has for its object to prevent the dissolution or inactivation of the enzymes and to avoid the rinsing of still usable enzymes.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß dem Wasch- oder Reinigungsprozess gegenüber typischen Verschmutzungen katalytisch wirkende Enzyme beigegeben werden und zwar nur so lange, wie ihre katalytische Wirkung gewünscht ist. Da die katalytische Wirkung der Enzyme nur in einem niedrigen Temperaturbereich und möglichst ohne Anwesenheit von alkalischen Reinigungsmitteln gut nutzbar ist, können die verwendeten Enzyme nach ihrem Einsatz wieder aus dem Waschprozess genommen und in einem späteren Waschprozess wieder verwendet werden. Die Aufgabe wird gelöst durch

  1. a) einen Verfahren zum maschinellen Reinigen von Textilien oder festen Gegenständen, wie Geschirr, unter Anwendung von in Wasser löslichen Wasch- und/oder Reinigungsmitteln und Enzymen, dadurch gekennzeichnet, dass dem Wasch- oder Reinigungsprozess in der Maschine für mindestens mehrere Reinigungszyklen deponierte, gegenüber typischen Verschmutzungen katalytisch wirkende Enzyme (E) beigegeben werden und zwar getrennt von den Wasch- oder Reinigungsmitteln (W) und nur so lange (t1), wie ihre katalytische Wirkung gewünscht ist,
  2. b) einen Enzymatischen Gebilde zur Verwendung in einem Verfahren nach Anspruch 1, dadurch gekennzeichnet, dass die Enzyme (7) mittels einer waschlaugendurchlässigen aber wasserunlöslichen Polymermembran makroskopisch gekapselt sind,
  3. c) einer Anordnung umfassend eine Maschine zum maschinellen Reinigen von Textilien oder festen Gegenständen, wie Geschirr, mittels Wasch- und/oder Reinigungsmitteln und Enzymen, dadurch gekennzeichnet, dass in der Maschine für mindestens mehrere Reinigungszyklen bestimmte, gegenüber typischen Verschmutzungen katalytisch wirkende Enzyme (E) getrennt von den Wasch- oder Reinigungsmitteln (W) deponiert sind und nur so lange (t1), wie ihre katalytische Wirkung gewünscht ist, dass die Enzyme in Kapseln (12) mittels einer waschlaugendurchlässigen aber wasserunlöslichen Polymermembran makroskopisch gekapselt sind, und dass die Kapseln (12) an einem von der Wasch- oder Reinigungslauge erreichbaren Ort (6) in der Maschine fest aber austauschbar angeordnet sind.
According to the invention, this object is achieved in that the washing or cleaning process with respect to typical soiling catalytically active enzymes are added and only as long as their catalytic effect is desired. Since the catalytic action of the enzymes is useful only in a low temperature range and possibly without the presence of alkaline detergents, the enzymes used can be removed from the washing process after use and reused in a later washing process. The task is solved by
  1. a) a method for machine cleaning of textiles or solid objects, such as dishes, using water-soluble detergents and / or detergents and enzymes, characterized in that the washing or cleaning process in the machine deposited for at least several cleaning cycles, opposite typical soiling catalytically active enzymes (E) are added and that separated from the washing or cleaning agents (W) and only as long (t 1 ) as their catalytic effect is desired,
  2. b) an enzymatic structure for use in a process according to claim 1, characterized in that the enzymes (7) are macroscopically encapsulated by means of a wash-slab-permeable but water-insoluble polymer membrane,
  3. c) an arrangement comprising a machine for machine cleaning of textiles or solid objects, such as dishes, by means of detergents and / or cleaning agents and enzymes, characterized in that in the machine for at least several cleaning cycles specific, against typical contaminants catalytically acting enzymes (E. ) are deposited separately from the washing or cleaning agents (W) and only as long as (t 1 ), as their catalytic effect is desired, that the enzymes in capsules (12) are encapsulated macroscopically by means of a washable but water insoluble polymer membrane, and Capsules (12) are fixedly but exchangeably arranged in the machine at a location (6) which can be reached by the washing or cleaning liquor.

In besonders vorteilhafter Weise ist das erfindungsgemäße Verfahren mit einem Wasch- oder Reinigungsmittel durchzuführen, bei dem die Enzyme mittels einer waschlaugendurchlässigen aber wasserunlöslichen Polymermembran makroskopisch gekapselt sind. Dadurch kann die katalytische Wirkung durch die Membran hindurch erfolgen, ohne daß sich die Enzyme in der Wasch- oder Reinigungslauge verteilen.In a particularly advantageous manner, the process according to the invention is to be carried out with a washing or cleaning agent in which the enzymes are macroscopically encapsulated by means of a wash-membrane-permeable but water-insoluble polymer membrane. As a result, the catalytic effect can be carried out through the membrane without the enzymes being distributed in the washing or cleaning liquor.

Wenn gemäß einer weiteren vorteilhaften Ausbildung der Erfindung die Kapseln aus mehreren miteinander verbundenen Hohlkörpern bestehen, sind die enzymbeladenen Membrankörper am einfachsten aus dem Kreislauf der Lauge - z. B. beim Abpumpen - herauszuhalten. So können die Hohlkörper zu Patronen und/oder Platten und/oder Rohrkörpern verbunden sein. Dadurch wird aus ihnen eine größere Einheit, die mechanisch am einfachsten in der Laugenströmung aufgehalten werden kann.If according to a further advantageous embodiment of the invention, the capsules consist of several interconnected hollow bodies, the enzyme-loaded membrane body are the easiest from the circulation of the liquor -. B. when pumping - stick out. Thus, the hollow body can be connected to cartridges and / or plates and / or tubular bodies. As a result, they become a larger unit, which can be stopped mechanically most easily in the lye flow.

Da auch bei Anwendung des erfindungsgemäßen Verfahrens die Enzyme sich allmählich verbrauchen - Alkali-Reste und temperaturbedingte Zerfallsprozesse sind dafür verantwortlich - , können gemäß einer besonders vorteilhaften Ausbildung beim erfindungsgemäßen enzymatischen Gebilde die Kapseln bzw. die verbundenen Hohlkörper in einer Maschine zum Reinigen von Textilien oder festen Gegenständen (z.B. Geschirr) an einem von der Wasch- oder Reinigungslauge erreichbaren Ort fest aber austauschbar angeordnet sein.Since the enzymes are gradually consumed even when using the method according to the invention - alkaline residues and temperature-induced decomposition processes are responsible - can, according to a particularly advantageous embodiment of the inventive enzymatic structure, the capsules or the connected hollow body in a machine for cleaning textiles or solid Objects (eg crockery) at one of the washing or cleaning solution reachable place but be arranged interchangeable.

In einem solchen Fall ist der Ort am zweckmäßigsten durch ein Filter gegen unlösliche Verunreinigungen aus der Wasch- oder Reinigungslauge geschützt.In such a case, the location is most conveniently protected by a filter against insoluble contaminants from the washing or cleaning liquor.

Damit alle Arten von eiweißhaltigen oder kohlehydrathaltigen Verschmutzungen in der Enzymphase des Wasch- oder Reinigungsprozesses betroffen werden, sind vorteilhafterweise Kapseln oder Hohlkörper mit auf unterschiedliche Verschmutzungsarten eingestellten Enzymen gefüllt. Am besten ist für jede in maschinell anwendbaren Wasch- oder Reinigungsprozessen auftretende Verschmutzungart ein spezielles Enzym vorgesehen.So that all types of protein-containing or carbohydrate-containing contaminants are affected in the enzyme phase of the washing or cleaning process, capsules or hollow bodies are advantageously filled with set to different types of pollution enzymes. It is best to use a special enzyme for every type of contamination that occurs in machine-washable or cleaning processes.

Die Ordinate O des Diagramm in Fig. 1 enthält nicht näher bezeichnete Maßstäbe für die Laugenmenge L im Laugenbehälter 1 der Waschmaschine in Fig. 2, für die Temperatur T der Lauge und für die Mengen an Waschmitteln W bzw. Enzymen E. Auf der Abszisse A ist ein nicht näher bezeichneter Zeitmaßstab Z aufgetragen.The ordinate O of the diagram in Fig. 1 contains unspecified scales for the amount of liquor L in the tub 1 of the washing machine in Fig. 2 , for the temperature T of the liquor and for the amounts of detergent W or enzymes E. On the abscissa A, an unspecified time scale Z is plotted.

Der im Diagramm der Fig. 1 dargestellte Waschprozess beginnt mit dem Einlauf von Wasser in den Laugenbehälter 1. Sobald ein gewisser Laugenstand L im Behälter 1 erreicht ist, wird die Lauge über eine begrenzte Zeit t1, in der die Laugentemperatur T noch niedrig ist, mit einer Menge von enzymatischem Wasch- oder Reinigungsmittel E in Kontakt gebracht, das in einem Wäscheposten eiweiß- und kohlehydrathaltige Verschmutzungen angreift. Danach wird ein beispielsweise alkalisches Waschmittel W in die Lauge L eingebracht, das über eine nicht weiter definierte Zeit t2 in der Lauge gelöst bleibt und auf die gelösten Eiweiße und Kohlehydrate sowie auf sonstige Verschmutzungen des Wäschepostens ablösend einwirkt. Die Flächen unterhalb der Diagrammlinien für Enzyme E und Waschmittel W machen den Unterschied der einzelnen Einwirkungsintensitäten deutlich.The in the diagram of Fig. 1 As soon as a certain level of liquor L in the container 1 is reached, the liquor is heated for a limited time t 1 , in which the liquor temperature T is still low, with a quantity of enzymatic washing. or detergent E brought into contact, which attacks protein and Kohlhydathaltige soils in a laundry. Thereafter, for example, an alkaline detergent W is introduced into the liquor L, which remains dissolved over a not further defined time t2 in the liquor and acts on the dissolved proteins and carbohydrates as well as other soiling of the Wäschepostens detaching. The areas below the diagram lines for Enzyme E and Detergent W highlight the difference in the individual exposure intensities.

Der Zulauf von Wasser unter Umgehung eines Waschmittelbehälters 2 für die erste Phase des Wasserzulaufs in Fig. 1 ist in Fig. 2 nicht dargestellt. Nachdem aber eine gewisse Menge an zugelaufenem Wasser den Boden des Laugenbehälters 1 bedeckt und die Wäsche bereits benetzt hat, wird im Beispiel der Fig. 2 die Laugenpumpe 3 eingeschaltet und das zugelaufene Wasser, soweit es nicht in der Wäsche gebunden ist, durch die Ablaufleitung 4 am Boden des Laugenbehälters und die Umlaufleitung 5 dem Enzymbehälter 6 zugeführt. Dort nimmt es eine begrenzte Menge von den bevorrateten Enzyme 7 auf und transportiert sie in den Laugenbehälter 1, von wo sie der Wäscheposten zusammen mit der die Wäsche wiederum benetzenden Lauge aufnimmt. Auf diese Weise wird durch dauernden Austausch von in der Wäsche gebundenem Wasser und Lauge allmählich der gesamte Wäscheposten mit Enzymen beaufschlagt. Dabei werden Eiweiße und Kohlehydrate aufgespalten. Die Enzymphase wird durch abschalten der Pumpe 3 beendet.The inlet of water, bypassing a detergent container 2 for the first phase of the water inlet in Fig. 1 is in Fig. 2 not shown. But after a certain amount of leaked water to the bottom of the tub 1 covered and already wet the laundry is in the example of the Fig. 2 the drain pump 3 turned on and the accumulated water, as far as it is not bound in the laundry, fed through the drain line 4 at the bottom of the tub and the circulation line 5 the Enzymbehälter 6. There it takes up a limited amount of the stored enzymes 7 and transports them into the tub 1, from where it receives the items of laundry together with the lye again wetting the laundry. In this way, by continuous exchange of bound in the laundry water and alkali gradually the entire laundry items are subjected to enzymes. This protein and carbohydrates are split. The enzyme phase is terminated by switching off the pump 3.

Demgegenüber wird nach Ende der Enzymphase das Waschmittel 8 aus dem Waschmittelbehälter 2 während der Öffnung des Ventils 9 durch Zulauf aus dem Wasserleitungsnetz 10 ausgespült und über die Leitung 11 dem Laugenbehälter 1 zugeführt. Dann kann ggf. unter weiterer Zufuhr von Wasser bis zum Erreichen einer gewünschten Laugenmenge L und unter Aufheizung der Lauge mittels einer nicht dargestellten Heizung bis zu einer gewünschten Temperatur T das Waschmittel W auf die aufgespaltenen Eiweiße und Kohlehydrate und auf die sonstigen Verschmutzungen am Wäscheposten einwirken und sie von der Wäsche ablösen. Später werden sie zusammen mit der verbrauchten Lauge auf nicht dargestellte Weise aus dem Laugenbehälter 1 in ein Abwassernetz gepumpt.In contrast, after the end of the enzyme phase, the detergent 8 is rinsed out of the detergent container 2 during the opening of the valve 9 by inlet from the water supply network 10 and fed via line 11 to the tub 1. Then, if necessary, with further supply of water until a desired amount of liquor L and heating the liquor by means of a heater not shown up to a desired temperature T, the detergent W act on the split proteins and carbohydrates and other contaminants on the laundry items and remove them from the laundry. Later they are pumped together with the spent liquor in a manner not shown from the tub 1 in a sewage network.

Enzyme 7 können durch Neuerungen in der Verfahrenstechnik (Mikrosysteme) mit einer dünnen, porösen Polymermembran überzogen werden, die die Enzyme in einer Kapsel beläßt, einen Stoffaustausch mit der Umgebung (erforderlich für den Zersetzungsprozeß der Eiweiße und Kohlehydrate beim Waschen) aber ermöglicht. Solche makroskopischen Kapseln können in Behältern 12 (siebartige Patronen oder Vernetzung der einzelnen Kapseln untereinander zu größeren Gebilden wie Platten, Rohrkörper, etc.) in entsprechenden Mengen für den jeweiligen Prozeß gebündelt werden und so als Bestandteil der Maschine im hydraulischen Kreislauf 3 bis 6 beibehalten werden. Um die Oberfläche der Kapseln vor Verschmutzungen zu schützen, die einen Stoffaustausch reduzieren oder verhindern würden, sind ggf. geeignete Filter 13 am Eingang und 14 am Ausgang des Enzymbehälters 6 vorzuschalten oder der Waschprozeß entsprechend zu gestalten.Enzymes 7 can be coated by innovations in process engineering (microsystems) with a thin, porous polymer membrane, which leaves the enzymes in a capsule, but allows an exchange of substances with the environment (required for the decomposition process of proteins and carbohydrates during washing). Such macroscopic capsules can be bundled in containers 12 (sieve-like cartridges or crosslinking of the individual capsules with one another into larger structures such as plates, tubular bodies, etc.) in appropriate amounts for the respective process and thus retained as part of the machine in the hydraulic circuit 3 to 6 , To the surface of the capsules from contamination to protect, which would reduce or prevent mass transfer, if appropriate, upstream filter 13 at the entrance and 14 at the output of Enzymbehälters 6 or make the washing process accordingly.

Das erfindungsgemäße Verfahren und das enzymatische Gebilde beinhalten damit die Möglichkeit zur vollständigen Vermeidung regelmäßiger Waschmittelzugaben durch den Kunden. Weder umweltbelastende Tensid-Waschmittel konventioneller Art noch enzymatischen Waschmittel in Pulverform sind beim Einsatz des erfindungsgemäßen Verfahrens in der Wasch- oder Reinigungsmittel erforderlich. Das weiterhin erforderliche enzymatische Gebilde wird beispielsweise in Patronenform als eine wenn nicht für die Dauer eines Wasch- oder Geschirrspülmaschinenlebens so doch zumindest für eine längere Zeit die Behandlungsmittel-Versorgung der Maschine bestreiten. Eine manuelle oder automatische Einzel-Dosierung von erfindungsgemäßen enzymatischen Gebilde bei jedem Waschvorgang kann entfallen und somit sowohl der Kunde entlastet wie die Umwelt deutlich geschont werden.The method according to the invention and the enzymatic structure thus include the possibility of completely avoiding regular detergent additions by the customer. Neither polluting surfactant detergents of conventional type nor enzymatic detergents in powder form are required when using the process according to the invention in the washing or cleaning agent. The enzymatic structure which is still required, for example in cartridge form, will be the treatment agent supply of the machine, if not for the duration of a washing or dishwashing machine life, at least for a longer time. A manual or automatic single-dose of enzymatic structure according to the invention in each washing process can be omitted and thus relieved both the customer and the environment can be spared significantly.

Um die verschiedenen Anforderungen an Enzyme in Abhängigkeit von der Verschmutzungsart zu berücksichtigen, können entweder für jede Enzymart ein eigenes Gebilde oder Gemische verschiedener Enzyme in einem Gebilde oder einer Patrone untergebracht werden.In order to take into account the different requirements of enzymes depending on the type of contamination, either a separate structure or mixtures of different enzymes can be accommodated in a structure or a cartridge for each type of enzyme.
