Definitions
- the invention relates to a detergent package with a plurality of detergent units for the preparation of a respective cleaning liquid for a single flushing of the milk lines of a milk processing system of a coffee machine.
- the invention further relates to a method for cleaning the milk lines of a milk processing plant of a coffee machine, in which method the milk lines are rinsed at intervals with a cleaning liquid.
- latte macchiato requires that there be a layer of milk under the coffee and a milk foam cap over the coffee.
- the coffee brewing chamber in particular is treated with an alkaline oxygen scavenger.
- an oxygen cleaner contains, for example, 20% sodium carbonate, 16% sodium bicarbonate, 24% sodium percarbonate, 6% surfactants and other auxiliaries.
- the EP-A-0 997 093 describes a fully automatic machine for the production of coffee drinks such as milk coffee and cappuccino.
- This machine has a separate circuit for the production of hot or foamed milk.
- To clean the milk processing system it is rinsed with hot steam after each cycle in which hot or foamed milk is provided.
- the components of the milk processing system may be periodically cleaned with a cleaning fluid.
- the milk processing system communicates with a container in which cleaning liquid is stored.
- the WO 2007/103635 discloses a detergent unit for cleaning vending machines that can deliver cold and hot drinks (including milk drinks).
- the detergent unit consists of a water-soluble capsule, which with a powdered detergent composition is filled.
- the detergent composition contains chelating agents, persalts, chalk sols, alkaline components, and optionally further adjuvants.
- a disadvantage of this cleaning agent unit is that the alkaline cleaning composition is unable to dissolve milk stone.
- a detergent package one or more sets of detergent units are conveniently arranged.
- the detergent units are conveniently arranged in the desired removal order in sets and combined one or more of these sets into a detergent package.
- the detergent units may be packaged in sets and several such individually packaged sets may be present in a detergent package. Conveniently, the sets are assembled and packaged at the factory. You can also have several sets that are not individually packaged in one package.
- the packing can serve as a dispenser, so that in each case a detergent unit is ready to hand in the pack, which is determined by the arrangement of the detergent units in the pack, how many times a detergent unit with basic detergent is readily available until a detergent unit with acid detergent is available.
- a dispenser may also be provided, into which a detergent package, a single or several (eg individually packaged) sets of detergent units can be inserted, so that in the dispenser the detergent units of the desired (defined by the order of the detergent units in the set) removal sequence are arranged accordingly.
- a detergent package therefore expediently comprises at least one set of detergent units, of which detergent units each contains the amount of detergent sufficient to produce the cleaning fluid for a single irrigation of the milk lines of a milk processing system of a coffee machine.
- Each such set comprises a plurality of first detergent units containing a basic detergent, and a single second detergent unit containing an acidic, especially milk stone dissolving detergent.
- the individual detergent units are advantageously arranged in a predetermined removal sequence.
- a single second detergent unit is ready for handing in the pack.
- first detergent units are present with the alkaline detergent.
- the ratio of alkaline cleaning units to acidic detergent units is in the range of 8 to 10.
- the second acidic detergent unit must contain about 8 to 10 times greater amount of detergent than the alkaline first detergent units. Because of in the basic and acidic Cleansing units contained different amounts, the two different units are immediately distinguishable. Stratification may therefore be such that a second detergent unit fills a cross-section of a package, and the first detergent units lie in two or three layers to three or two detergent units thereon.
- the detergent pack is a pack which can be used as a unit dispenser, in which case only a single detergent unit is present at hand. In this case, each detergent unit fills the cross-section of the package.
- the alkaline cleaning agent advantageously contains sodium metasilicate, which has a strong alkalinity for saponifying the milk fat.
- Components of the alkaline cleaning agent may include alkali hydroxides (eg NaOH, KOH), alkali silicates (eg metasilicates, water glasses), inorganic phosphates (eg tri-, meta- or pyrophosphates), complexing agents (eg NTA, EDTA, salts of phosphoric acid, citrates) and surfactants ,
- alkali hydroxides eg NaOH, KOH
- alkali silicates eg metasilicates, water glasses
- inorganic phosphates eg tri-, meta- or pyrophosphates
- complexing agents eg NTA, EDTA, salts of phosphoric acid, citrates
- surfactants e.g NTA, EDTA, salts of phosphoric acid, citrates
- the alkaline cleaning agent advantageously contains sodium tripolyphosphate.
- This complexing agent acts as a water softener. Secondarily, the tripoliphosphates
- the alkaline cleaning agent advantageously contains 35 to 55%, in particular 40 to 50% sodium metasilicate and 15 to 30%, in particular 18 to 27% sodium tripolyphosphate (all percentages in percentages by weight). Thus, with little substance a sufficiently high alkalinity and washing activity can be achieved. After dissolution of the salt in water, a detergent concentration of only 0.6% results in the liquid used for the cleaning.
- the alkaline cleaning agent expediently contains 2 to 10%, in particular 3 to 8%, of surfactants, in particular anionic surfactants. These surfactants are used to lower the surface tension of the water.
- the alkaline cleaning agent also preferably contains 15 to 35%, especially more than 17% sodium carbonate.
- a composition containing sodium metasilicate 5 hydrate may be classified within a low hazard class if used in limited quantities. In order to maintain the alkalinity despite a limited amount of this substance, is worked to supplement to 100% with sodium carbonate (soda) and omitted skeletal substances. Soda does not affect the hazard class.
- the alkaline cleaning agent conveniently additionally contains a bactericide.
- a germicidal compound preferably 2 to 10%, in particular 3 to 8% sodium dichloroisocyanurate is used.
- the acidic cleaning agent preferably contains phosphoric acid and / or sulfamic acid, nonionic surfactants and auxiliaries such as dispersants, solubilizers and corrosion inhibitors.
- the acid detergent contains surfactants, in particular cationic surfactants, one or more polycarboxylic acids and sulfamic acid. Milkstone can only be removed with acidic media. As acids are preferably those compounds are used which do not attack the material to be cleaned.
- the acidic cleaning agent conveniently contains from 3 to 12%, in particular from 4 to 10%, of surfactants which are stable in acidic medium.
- the acidic cleaning agent preferably contains from 35 to 55% and most preferably from 40 to 50% of sulfamic acid.
- the acidic cleaning agent also contains 40 to 60%, preferably 40 to 50 wt .-% of one or more dicarboxylic acids, in particular citric acid.

Abstract
Description
Die Erfindung betrifft einen Reinigungsmittelpacken mit einer Mehrzahl von Reinigungsmitteleinheiten für die Herstellung jeweils einer Reinigungsflüssigkeit für eine einzelne Spülung der Milchleitungen einer Milchaufbereitungsanlage einer Kaffeemaschine. Die Erfindung betrifft weiter ein Verfahren zur Reinigung der Milchleitungen einer Milchaufbereitungsanlage einer Kaffeemaschine, bei welchem Verfahren die Milchleitungen in zeitlichen Abständen mit einer Reinigungsflüssigkeit gespült werden.The invention relates to a detergent package with a plurality of detergent units for the preparation of a respective cleaning liquid for a single flushing of the milk lines of a milk processing system of a coffee machine. The invention further relates to a method for cleaning the milk lines of a milk processing plant of a coffee machine, in which method the milk lines are rinsed at intervals with a cleaning liquid.
Beim Kaffeegenuss hat sich seit einigen Jahren eine neue Genussrichtung durchgesetzt, bei der der Kaffee mit Milch, insbesondere mit Milchschaum verfeinert ist. Zu diesen Getränken gehört der sogenannte Latte Macchiato, die Schale, der Caffè Latte und der Cappuccino. Beim Latte Macchiato beispielsweise ist es erforderlich, dass unter dem Kaffee eine Milchschicht und über dem Kaffee eine Milchschaumhaube vorliegt.For a few years now, the enjoyment of coffee has gained a new direction of enjoyment in which the coffee is refined with milk, in particular milk froth. These drinks include the so-called latte macchiato, the bowl, the caffè latte and the cappuccino. For example, latte macchiato requires that there be a layer of milk under the coffee and a milk foam cap over the coffee.
Zur Erzeugung von warmer Milch und von Milchschaum sind neuere Kaffeemaschinen mit einer Milchaufbereitungsanlage ausgestattet. Diese Milchaufbereitungsanlage erlaubt neben der Herstellung oben angeführter Kaffee-Milch-Spezialitäten auch die Zubereitung von heisser Milch, Kakao-, Mokka- und Schokolade-Getränken. Die neuen Milchaufbereitungsanlagen stellen die Betreiber der Kaffeemaschinen vor neue Herausforderungen, da in den Milchaufbereitungsanlagen neuartige Verschmutzungen auftreten. Da es sich dabei um Verschmutzungen der Milchleitungen handelt, sind sehr hohe hygienische Anforderungen zu erfüllen.For the production of warm milk and milk foam newer coffee machines are equipped with a milk processing plant. This milk processing plant also allows the preparation of hot milk, cocoa, mocha and chocolate drinks in addition to the above-mentioned coffee-milk specialties. The new milk processing plants pose new challenges for the operators of the coffee machines, since new types of soiling occur in the milk processing plants. Since these are soiling of the milk pipes, very high hygienic requirements must be met.
Zur Reinigung von Kaffeemaschinen wird insbesondere die Kaffeebrühkammer mit einem alkalischen Sauerstoffreiniger behandelt. Ein solcher Sauerstoffreiniger enthält beispielsweise 20% Natriumcarbonat, 16% Natriumbicarbonat, 24% Natriumpercarbonat, 6% Tenside und weiter Hilfsstoffe. Bei einer Reinigung der Milchleitungen einer Milchaufbereitungsanlage einer Kaffeemaschine mit diesem für Kaffeemaschinen vorgesehenen Reinigungsmittel können die notwendigen hygienischen Anforderungen an diese Anlage nicht gewährleistet werden.For cleaning coffee machines, the coffee brewing chamber in particular is treated with an alkaline oxygen scavenger. Such an oxygen cleaner contains, for example, 20% sodium carbonate, 16% sodium bicarbonate, 24% sodium percarbonate, 6% surfactants and other auxiliaries. When cleaning the milk lines of a milk processing system of a coffee machine with this intended for coffee machines cleaning agents the necessary hygienic requirements for this system can not be guaranteed.
Es ist bekannt, für die Reinigung von Milchleitungen von Melkanlagen ein Reinigungsmittel zu verwenden, das wenigstens 30% Zitronensäure, weniger als 5% Glycolsäure und weniger als 5% nichtionische Tenside enthält. Ein solches saures Reinigungsmittel ist notwendig, damit sich in den Milchleitungen kein Milchstein bildet, beziehungsweise gebildeter Milchstein aufgelöst wird.It is known to use a detergent containing at least 30% citric acid, less than 5% glycolic acid and less than 5% nonionic surfactants for cleaning milking lines of milking parlors. Such an acidic cleaning agent is necessary so that no milkstone forms in the milk lines, or formed milkstone is dissolved.
Im Bereich von Kaffeemaschinen sind jedoch andere Bedingungen als bei Melkanlagen zu erwarten, da in den Milchaufbereitungsanlagen der Kaffeemaschinen die Milch erhitzt wird.In the field of coffee machines, however, other conditions than in milking systems are to be expected since the milk is heated in the milk processing systems of the coffee machines.
Die
Die
Es ist Aufgabe der Erfindung, Reinigungsmittel bereitzustellen, deren Anwendung sehr einfach ist und hilft, die geforderten hygienischen Bedingungen zu erfüllen. Es ist eine weitere Aufgabe, ein Verfahren vorzuschlagen, mit welchem die Milchleitungen von Milchaufbereitungsanlagen in Kaffeemaschinen hygienisch einwandfrei gehalten werden können.It is an object of the invention to provide cleaning agents whose application is very simple and helps to meet the required hygienic conditions. It is a further object to propose a method by which the milk lines of milk processing plants in coffee machines can be kept hygienic.
Diese Aufgabe wird durch einen Reinigungsmittelpacken gemäss dem entsprechenden unabhängigen Anspruch und durch ein erfindungsgemässes Verfahren gemäss dem unabhängigen Verfahrensanspruch gelöst.This object is achieved by a detergent package according to the corresponding independent claim and by a method according to the invention according to the independent method claim.
In einem Reinigungsmittelpacken sind zweckmässigerweise ein oder mehrere Sets von Reinigungsmitteleinheiten angeordnet. Die Reinigungsmitteleinheiten sind zweckmässigerweise in der gewünschten Entnahme-Reihenfolge in Sets angeordnet und eines oder mehrere dieser Sets in zu einem Reinigungsmittelpacken zusammengefasst. Es können die Reinigungsmitteleinheiten setweise abgepackt sein und mehrere solche einzeln abgepackten Sets in einem Reinigungsmittelpacken vorliegen. Zweckmässigerweise werden die Sets werkseitig zusammengestellt und abgepackt. Es können auch mehrere nicht einzeln abgepackte Sets in einem Packen zusammengefasst vorliegen. Der Packen kann als Spender dienen, so dass jeweils eine Reinigungsmitteleinheit griffbereit im Packen vorliegt, wobei durch die Anordnung der Reinigungsmitteleinheiten im Packen festgelegt ist, wie viele Male eine Reinigungsmitteleinheit mit basischem Reinigungsmittel griffbereit vorliegt, bis eine Reinigungsmitteleinheit mit saurem Reinigungsmittel griffbereit vorliegt.In a detergent package, one or more sets of detergent units are conveniently arranged. The detergent units are conveniently arranged in the desired removal order in sets and combined one or more of these sets into a detergent package. The detergent units may be packaged in sets and several such individually packaged sets may be present in a detergent package. Conveniently, the sets are assembled and packaged at the factory. You can also have several sets that are not individually packaged in one package. The packing can serve as a dispenser, so that in each case a detergent unit is ready to hand in the pack, which is determined by the arrangement of the detergent units in the pack, how many times a detergent unit with basic detergent is readily available until a detergent unit with acid detergent is available.
Es kann auch ein Spender vorgesehen sein, in den ein Reinigungsmittelpacken, ein einzelnes oder mehrere (z.B. einzeln abgepackte) Sets an Reinigungsmitteleinheiten eingelegt werden können, so dass im Spender die Reinigungsmitteleinheiten der gewünschten (durch die Reihenfolge der Reinigungsmitteleinheiten im Set definierten) Entnahme-Reihenfolge entsprechend angeordnet sind.A dispenser may also be provided, into which a detergent package, a single or several (eg individually packaged) sets of detergent units can be inserted, so that in the dispenser the detergent units of the desired (defined by the order of the detergent units in the set) removal sequence are arranged accordingly.
Ein Reinigungsmittelpacken umfasst daher zweckmässigerweise wenigstens ein Set von Reinigungsmitteleinheiten, von welchen Reinigungsmitteleinheiten jede diejenige Menge an Reinigungsmittel enthält, die für die Herstellung der Reinigungsflüssigkeit für eine einzelne Spülung der Milchleitungen einer Milchaufbereitungsanlage einer Kaffeemaschine ausreicht. Jedes solche Set umfasst eine Mehrzahl von ersten Reinigungsmitteleinheiten, die ein basisches Reinigungsmittel enthalten, und eine einzelne zweite Reinigungsmitteleinheit, die ein saures, insbesondere Milchstein auflösendes Reinigungsmittel enthält.A detergent package therefore expediently comprises at least one set of detergent units, of which detergent units each contains the amount of detergent sufficient to produce the cleaning fluid for a single irrigation of the milk lines of a milk processing system of a coffee machine. Each such set comprises a plurality of first detergent units containing a basic detergent, and a single second detergent unit containing an acidic, especially milk stone dissolving detergent.
In einem Set sind daher vorteilhaft die einzelnen Reinigungsmitteleinheiten in einer vorbestimmten Entnahme-Abfolge angeordnet. Bei einer Nach-Und-Nach-Entnahme einzelner Reinigungsmitteleinheiten liegt nach einer Entnahme einer bestimmten Mehrzahl von ersten Reinigungsmitteleinheiten eine einzelne zweite Reinigungsmitteleinheit griffbereit im Packen vor.In a set, therefore, the individual detergent units are advantageously arranged in a predetermined removal sequence. In the case of a subsequent removal of individual detergent units after removal of a certain plurality of first detergent units, a single second detergent unit is ready for handing in the pack.
In einem Set liegen vorteilhaft neben der einzelnen sauren zweiten Reinigungsmitteleinheit jeweils 6 bis 12 erste Reinigungsmitteleinheiten mit dem alkalischen Reinigungsmittel vor. Vorzugsweise liegt das Verhältnis von alkalischen Reinigungseinheiten zu sauren Reinigungsmitteleinheiten im Bereich von 8 bis 10.In a set, in addition to the individual acidic second detergent unit, in each case 6 to 12 first detergent units are present with the alkaline detergent. Preferably, the ratio of alkaline cleaning units to acidic detergent units is in the range of 8 to 10.
Es hat sich gezeigt, dass die zweite saure Reinigungsmitteleinheit eine etwa 8 bis 10 mal grössere Menge an Reinigungsmittel enthalten muss als die alkalischen ersten Reinigungsmitteleinheiten. Aufgrund der in den basischen und sauren Reinigungseinheiten enthaltenen unterschiedlichen Mengen sind die beiden verschiedenen Einheiten sofort unterscheidbar. Eine Schichtung kann daher so erfolgen, dass eine zweite Reinigungsmitteleinheit einen Querschnitt einer Verpackung auffüllt, und die ersten Reinigungsmitteleinheiten in zwei oder drei Schichten zu drei oder zwei Reinigungsmitteleinheiten darauf liegen.It has been found that the second acidic detergent unit must contain about 8 to 10 times greater amount of detergent than the alkaline first detergent units. Because of in the basic and acidic Cleansing units contained different amounts, the two different units are immediately distinguishable. Stratification may therefore be such that a second detergent unit fills a cross-section of a package, and the first detergent units lie in two or three layers to three or two detergent units thereon.
Es kann auch vorgesehen sein, dass der Reinigungsmittelpacken eine als Einheitenspender nutzbare Packung ist, bei welcher jeweils lediglich eine einzelne Reinigungsmitteleinheit griffbereit vorliegt. In diesem Fall füllt jede Reinigungsmitteleinheit den Querschnitt der Packung aus.It can also be provided that the detergent pack is a pack which can be used as a unit dispenser, in which case only a single detergent unit is present at hand. In this case, each detergent unit fills the cross-section of the package.
Es werden auch vorteilhafte Zusammensetzungen der Reinigungsmittel vorgeschlagen. Das alkalische Reinigungsmittel enthält vorteilhaft Natriummetasilikat, das eine starke Alkalität zum Verseifen des Milchfettes aufweist.There are also proposed advantageous compositions of the detergents. The alkaline cleaning agent advantageously contains sodium metasilicate, which has a strong alkalinity for saponifying the milk fat.
Komponenten des alkalischen Reinigungsmittels könenn Alkalihydroxide (z.B. NaOH, KOH), Alkalisilikate (z.B. Metasilikate, Wassergläser), Anorganische Phosphate (z.B. Tri-, Meta - oder Pyrophosphate), Komplexbildner (z.B. NTA, EDTA, Solze von Phosphorsäure, Citrate) und Tenside enthalten. Das alkalische Reinigungsmittel enthält vorteilhaft Natriumtripolyphosphat. Dieser Komplexbildner wirkt als Wasserenthärter. Sekundär helfen die Tripoliphosphate den Schmutz abzulösen und zu transportieren.Components of the alkaline cleaning agent may include alkali hydroxides (eg NaOH, KOH), alkali silicates (eg metasilicates, water glasses), inorganic phosphates (eg tri-, meta- or pyrophosphates), complexing agents (eg NTA, EDTA, salts of phosphoric acid, citrates) and surfactants , The alkaline cleaning agent advantageously contains sodium tripolyphosphate. This complexing agent acts as a water softener. Secondarily, the tripoliphosphates help to loosen and transport the dirt.
Das alkalische Reinigungsmittel enthält mit Vorteil 35 bis 55%, insbesondere 40 bis 50% Natriummetasilikat und 15 bis 30%, insbesondere 18 bis 27 % Natriumtripolyphosphat (alle Prozentangaben in Gewichtsprozenten). So kann mit wenig Substanz eine genügend hohe Alkalität und Waschaktivität erreicht werden. Nach der Auflösung des Salzes in Wasser ergibt sich eine Waschmittelkonzentration von lediglich 0,6% in der für die Reinigung verwendeten Flüssigkeit.The alkaline cleaning agent advantageously contains 35 to 55%, in particular 40 to 50% sodium metasilicate and 15 to 30%, in particular 18 to 27% sodium tripolyphosphate (all percentages in percentages by weight). Thus, with little substance a sufficiently high alkalinity and washing activity can be achieved. After dissolution of the salt in water, a detergent concentration of only 0.6% results in the liquid used for the cleaning.
Das alkalische Reinigungsmittel enthält zweckmässigerweise 2 bis 10 %, insbesondere 3 bis 8% Tenside, insbesondere anionische Tenside. Diese Tenside werden eingesetzt, um die Oberflächenspannung des Wassers herabzusetzen.The alkaline cleaning agent expediently contains 2 to 10%, in particular 3 to 8%, of surfactants, in particular anionic surfactants. These surfactants are used to lower the surface tension of the water.
Das alkalische Reinigungsmittel enthält ausserdem vorzugsweise 15 bis 35%, insbesondere mehr als 17% Natriumcarbonat. Eine Zusammensetzung mit Natriummetasilikat 5-Hydrat kann, sofern diese Substanz in beschränkter Menge eingesetzt wird, innerhalb einer niedrigen Gefahrenklasse eingestuft werden. Um die Alkalität trotz einer beschränkten Menge dieser Substanz aufrecht zu erhalten, wird zur Ergänzung auf 100% mit Natriumcarbonat (Soda) gearbeitet und auf Skelettstoffe verzichtet. Soda tangiert die Gefahrenklasse nicht.The alkaline cleaning agent also preferably contains 15 to 35%, especially more than 17% sodium carbonate. A composition containing sodium metasilicate 5 hydrate may be classified within a low hazard class if used in limited quantities. In order to maintain the alkalinity despite a limited amount of this substance, is worked to supplement to 100% with sodium carbonate (soda) and omitted skeletal substances. Soda does not affect the hazard class.
Das alkalische Reinigungsmittel enthält zweckmässigerweise zusätzlich ein Bakterizid. Als keimabtötende Verbindung wird vorzugsweise 2 bis 10 %, insbesondere 3 bis 8% Natriumdichlorisocyanurat eingesetzt.The alkaline cleaning agent conveniently additionally contains a bactericide. As a germicidal compound preferably 2 to 10%, in particular 3 to 8% sodium dichloroisocyanurate is used.
Das saure Reinigungsmittel enthält vorzugsweise Phosphorsäure und/oder Sulfaminsäure, nichtionische Tenside und Hilfsstoffe wie Diespergatoren, Lösungsvermittler und Korrosionsinhibitoren. Vorteilhaft enthält das saure Reinigugnsmittel Tenside, insbesondere kationische Tenside, eine oder mehrere Polycarbonsäuren und Sulfaminsäure. Milchstein lässt sich nur mit sauren Medien entfernen. Als Säuren kommen vorzugsweise solche Verbindungen zum Einsatz, die das zu reinigende Material nicht angreifen.The acidic cleaning agent preferably contains phosphoric acid and / or sulfamic acid, nonionic surfactants and auxiliaries such as dispersants, solubilizers and corrosion inhibitors. Advantageously, the acid detergent contains surfactants, in particular cationic surfactants, one or more polycarboxylic acids and sulfamic acid. Milkstone can only be removed with acidic media. As acids are preferably those compounds are used which do not attack the material to be cleaned.
Das saure Reinigungsmittel enthält zweckmässigerweise 3 bis 12 %, insbesondere 4 bis 10% Tenside, welche in saurem Milieu beständig sind.The acidic cleaning agent conveniently contains from 3 to 12%, in particular from 4 to 10%, of surfactants which are stable in acidic medium.
Das saure Reinigungsmittel enthält vorzugsweise 35 bis 55% und ganz besonders bevorzugt 40 bis 50 % Sulfaminsäure.The acidic cleaning agent preferably contains from 35 to 55% and most preferably from 40 to 50% of sulfamic acid.
Das saure Reinigungsmittel enthält ausserdem 40 bis 60 %, vorzugsweise 40 bis 50 Gew.-% einer oder mehrer Dicarbonsäuren, insbesondere Zitronensäure. Andere geeignete Dicarbonsäuren sind Oxalsäure, Malonsäure, Weinsäure, Apfelsäure oder Bernsteinsäure.The acidic cleaning agent also contains 40 to 60%, preferably 40 to 50 wt .-% of one or more dicarboxylic acids, in particular citric acid. Other suitable dicarboxylic acids are oxalic acid, malonic acid, tartaric acid, malic acid or succinic acid.
Für eine konkrete Rezeptur müssen die Gefahrenklasse und die Ökobilanz berücksichtigt werden.For a specific recipe, the hazard class and the life cycle assessment must be taken into account.
Bei einem Verfahren zur Reinigung der Milchleitungen einer Milchaufbereitungsanlage einer Kaffeemaschine werden die Milchleitungen in zeitlichen Abständen mit einer Reinigungsflüssigkeit gespült. Erfindungsgemäss werden die Milchleitungen jeweils innerhalb eines Zeitintervalls mehrmals mit einer basischen Reinigungsflüssigkeit und einmal mit einer sauren Reinigungsflüssigkeit gespült. Die basische Reinigungsflüssigkeit reinigt die Milchleitung von Fetten und desinfiziert deren Oberflächen. Die saure Reinigungsflüssigkeit entfernt vorhandene Kaseinablagerungen, den sogenannten Milchstein. Die Anzahl der Reinigungen mit einer basischen Reinigungsflüssigkeit wird erfindungsgemäss durch die Anzahl von ersten Reinigungsmitteleinheiten bestimmt, die ein basisches Reinigungsmittel enthalten und in einem Reinigungsmittelset enthalten sind, welches Reinigungsmittelset eine einzelne zweite Reinigungsmitteleinheit umfasst, die ein saures Reinigungsmittel enthält.In a method for cleaning the milk lines of a milk processing system of a coffee machine, the milk lines are rinsed at intervals with a cleaning liquid. According to the invention, the milk lines are each rinsed several times within a time interval with a basic cleaning liquid and once with an acidic cleaning liquid. The basic cleaning fluid cleans the milk line of fats and disinfects their surfaces. The acidic cleaning fluid removes existing casein deposits, the so-called milk stone. The number of cleanings with a basic cleaning liquid is determined according to the invention by the number of first detergent units containing a basic detergent and contained in a detergent set, which detergent set comprises a single second detergent unit containing an acid detergent.
Zweckmässigerweise werden die Milchleitungen jeweils in einem gegebenen Zeitintervall, z.B. innerhalb von 6 oder 12 Benutzungstagen, 6 bis 12 mal mit der basischen Reinigungsflüssigkeit gespült. Die Reinigung kann ein- oder zweimal täglich vorgenommen werden. Bevorzugt werden die Milchleitungen jeweils in einem Zeitintervall 8 bis 10 mal mit der basischen Reinigungsflüssigkeit gespült, bevor sie mit der sauren Reinigungsflüssigkeit gereinigt werden.Conveniently, the milk lines are each timed in a given time interval, e.g. within 6 or 12 days of use, rinsed 6 to 12 times with the basic cleaning fluid. The cleaning can be done once or twice a day. Preferably, the milk lines are each rinsed in a time interval 8 to 10 times with the basic cleaning liquid before they are cleaned with the acidic cleaning liquid.
Zweckmässigerweise wird die Reinigungsflüssigkeit aus einer einzelnen Reinigungsmitteleinheit und Wasser hergestellt. Diese Zusammensetzung ist sehr einfach zu erreichen. Vorteilhaft ist die in der Reinigungsmitteleinheit vorliegende Menge an Reinigungsmittel auf die Grösse und Art der Milchaufbereitungsanlage angepasst. Eine solche Einheit muss daher lediglich mit der vorgeschriebenen Menge an Wasser vermengt werden und dann durch die Milchaufbereitungsanlage geleitet werden.Conveniently, the cleaning liquid is prepared from a single detergent unit and water. This composition is very easy to reach. Advantageously, the amount of cleaning agent present in the cleaning agent unit is adapted to the size and type of the milk processing plant. Such a unit must therefore only be mixed with the prescribed amount of water and then passed through the milk processing plant.
Ein Set an Reinigungsmitteleinheiten umfasst daher eine Mehrzahl von ersten Reinigungsmitteleinheiten und eine einzelne zweite Reinigungsmitteleinheit. Diese können lose in einem Beutel angeordnet sein. Zur besseren Handhabung sollte die einzelne saure Reinigungsmitteleinheit besonders gekennzeichnet sein und kann so leicht beispielsweise als erste oder letzte dem Beutel entnommen werden. Dadurch ist die erfindungsgemässe Reihenfolge von mehreren basischen Reinigungen und einer sauren Reinigung kontrollefrei einzuhalten.A set of detergent units therefore comprises a plurality of first detergent units and a single second detergent unit. These can be arranged loosely in a bag. For better handling, the individual acid detergent unit should be specially marked and can thus be easily removed, for example, as the first or last of the bag. As a result, the sequence according to the invention of several basic cleanings and one acidic cleaning must be observed without any control.
Bei dem Verfahren werden die Reinigungsmitteleinheiten zweckmässigerweise in einem Reinigungsmittelpacken in einer solchen Reihenfolge angeordnet, dass eine saure Reinigungsmitteleinheit auf mehrere basische Reinigungsmitteleinheiten folgt. Im Reinigungsmittelpacken liegt wenigstens ein Set von Reinigungseinheiten vor. Ein solches Set umfasst eine Mehrzahl von ersten Reinigungsmitteleinheiten, die ein alkalisches Reinigungsmittel enthalten, und genau eine zweite Reinigungsmitteleinheit, die ein saures Reinigungsmittel enthält. Damit diese Entnahme in der für das Verfahren angezeigten Reihenfolge geschieht, sind die Reinigungsmitteleinheiten der gewünschten Entnahme-Abfolge entsprechend im Reinigungsmittelpacken angeordnet.In the method, the detergent units are conveniently arranged in a detergent package in such an order that an acidic detergent unit follows several basic detergent units. The detergent package contains at least one set of cleaning units. Such a kit comprises a plurality of first detergent units containing an alkaline detergent and exactly one second detergent unit containing an acidic detergent. In order for this removal to occur in the order indicated for the process, the detergent units of the desired removal sequence are arranged correspondingly in the detergent package.
Das Zeitintervall, innerhalb welchem eine Mehrzahl von alkalischen und eine einzelne saure Reinigung durchgeführt werden, umfasst zweckmässigerweise 6 bis 12 Tage. Bei einem Zeitintervall von 9 Tagen ergeben sich 8 alkalische Reinigungseinheiten auf eine saure Reinigungseinheit, was eine kompakte Verpackung und einen zweckmässigen Reinigungsrhythmus ergibt.The time interval within which a plurality of alkaline and a single acidic purification are carried out expediently comprises 6 to 12 days. At a time interval of 9 days, 8 alkaline cleaning units result in an acidic cleaning unit, resulting in compact packaging and a convenient cleaning rhythm.

Eine bevorzugte Reinigungsmittelpackung umfasst 9 Set mit je 8 alkalischen Reinigungsmitteleinheiten und je einer sauren Reinigungsmitteleinheit. Eine solche Reinigungsmittelpackung enthält damit 81 Reinigungsmitteleinheiten, was dem Bedarf für etwa 3 Monate Betriebsdauer der Kaffeemaschine entspricht. Eine solche Packung wiegt bei einer Dosierung für jeweils einen Liter Reinigungsflüssigkeit pro Reinigung und den nachfolgenden Zusammensetzungen weniger als ein Kilogramm.A preferred detergent pack comprises 9 sets each containing 8 alkaline detergent units and one acid detergent each. Such a detergent package thus contains 81 detergent units, which corresponds to the need for about 3 months of operation of the coffee machine. Such a pack weighs less than one kilogram when metered for one liter of cleaning fluid per cleaning and subsequent compositions.
Zusammensetzungen von Reinigungsmitteln sind im Folgenden beispielhaft angeführt:
Dass vorgeschlagene alkalische Reinigungsmittel ist ein Spezialreiniger für die Gewähr einer einwandfreien Betriebshygiene des Milchaufbereitungssystems einer Kaffeemaschine. Es kann preisgünstig hergestellt und in schlanken Beuteln bereitgestellt werden. Es werden davon ca. 6 Gramm (bevorzugter Bereich 3 bis 7 Gramm) pro Liter Wasser aufgelöst, und mit der Lösung die Milchaufbereitungsanlage gespült. Da die Menge des eingesetzten Spülwasser in modernen Kaffeemaschinen vorprogrammiert werden kann, ist die Anwendung ausgesprochen einfach.The proposed alkaline cleaning agent is a special cleaner for the guarantee of perfect operational hygiene of the milk processing system of a coffee machine. It can be inexpensively manufactured and provided in slim bags. It will be about 6 grams (preferred range 3 to 7 grams) per liter of water dissolved, and with the solution Rinsed milk processing plant. Since the amount of rinse water used can be preprogrammed in modern coffee machines, the application is extremely simple.
Andere, ähnlich wirkende, aber vom vorliegenden Rezept abweichende Formulierungen sind möglich. Statt Metasilikat könnte Dinatriumdisilikat verwendet werden. Anstelle von Tripolyphosphat könnte grundsätzlich auch Nitrilotriessigsäure verwendet werden. Da Nitrilotriessigsäure bezüglich möglicher Nebenwirkungen nicht vollkommen unbedenklich ist, wird jedoch Tripolyphosphat der Vorzug gegeben.Other, similar-acting, but deviating from the present recipe formulations are possible. Disodium disilicate could be used instead of metasilicate. In principle, nitrilotriacetic acid could also be used instead of tripolyphosphate. However, since nitrilotriacetic acid is not completely safe with respect to possible side effects, it is preferred to use tripolyphosphate.
Saures Reinigungsmittel zur Herstellung einer wässerigen Reinigungslösung
Das vorgeschlagene saure Reinigungsmittel hat eine ausgezeichnete Wirkung zur Entfernung von Milchstein. Diese Zusammensetzung ist kostengünstig herstellbar und umweltverträglich. Es hat auch den Vorteil, dass das Reinigungsmittel das Material der Leitungen nicht angreift. Vorzugsweise wird eine 3 bis 7 prozentige Reinigungslösung zur periodischen Reinigung der Milchaufbereitungsanlage verwendet. Zu diesem Zweck werden 30 bis 70 Gramm der pulverförmigen Reinigungszusammensetzung in einem Liter Wasser aufgelöst. In der Praxis wird vorzugsweise eine ungefähr 5%-ige Reinigungslösung verwendet.The proposed acidic cleaning agent has an excellent action for removal of milk stone. This composition is inexpensive to produce and environmentally friendly. It also has the advantage that the cleaning agent does not attack the material of the lines. Preferably, a 3 to 7 percent cleaning solution is used for periodic cleaning of the milk processing plant. For this purpose, 30 to 70 grams of the powdered detergent composition are dissolved in one liter of water. In practice, an approximately 5% cleaning solution is preferably used.
