Definitions
- the invention is in the field of cleaning pipelines and containers in the food industry, such as pipe and / or container cleaning in in the beverage industry, in breweries, dairy farms etc. It relates to the use of cleaning agents known per se for hard surfaces in one Process that cleans the inside of pipes and / or containers.
- CIP cleaning-in-place
- COP cleaning-on-place
- the inner surfaces of pipes and containers are cleaned using the CIP process.
- detergent solutions and rinsing water are provided in tanks with a volume of 2 - 20,000 liters in so-called CIP tanks.
- the cleaning and rinsing liquids are fed to the tank or piping system to be cleaned by means of a pump via valves and pipelines and applied as static film or rotating spray systems as a trickle film or by flooding on their inner walls.
- the cleaning effect results from the chemical / physical cleaning effect of the applied cleaning solution, the cleaning temperature, the treatment time and the mechanical cleaning effect.
- the cleaning liquids run under the tank or out of the pipelines and are returned to the CIP tanks by means of a second pump via a return line with appropriate valves.
- the pre-rinse water is usually directed to the sewage system, and fresh water used as rinse water is collected in the pre-rinse tank for the next pre-rinse. More complex cleaning processes consist of several cleaning steps and one disinfection step.
- the individual cleaning steps and disinfection are separated by an intermediate rinse with fresh water.
- the intermediate rinses serve to return the cleaning solutions and remove the residues from the tank and pipe walls.
- the solutions from the intermediate rinses are usually also fed to the pre-rinse tank.
- CIP systems for this more complex process have correspondingly more CIP tanks, e.g. pre-rinse tank, tank for alkaline cleaning, tank for acid cleaning, disinfectant tank and fresh water tank. If necessary, the detergent tanks are designed to be heated so that hot cleaning can be carried out.
- the process described above is referred to as "stacked" CIP cleaning or "stack cleaning", since here the solutions are "stacked" in the CIP tanks for reuse, if necessary after cleaning by membrane filtration. In contrast to this, with the "lost" cleaning variant, the solutions are fed into the sewerage at the end of the cleaning step and not "stacked".
- Losses of water and detergents are retained during batch cleaning Limits, with a well-set CIP procedure one expects a loss of 5 - 10%.
- This Losses refer to the volume that is in the supply lines from the CIP tank to the spray head on the tank to be cleaned, in the tank itself and in the return line the so-called circulation volume. The losses arise through partial Mixing of the individual phases (pre-rinse water, cleaning agent solutions, Rinsing water) in the pipes and especially in the tank as well as switching delays when switching valves.
- foam-free cleaning solutions are used. This is because e.g. one only half-full pipe, the other half with foam on the cleaning solution floats, is wetted, and is completely cleaned, since the mechanical and chemical cleaning power of the foam does not match that of the cleaning solution. Foaming is also undesirable in containers because the foam is rinsed out considerable time and water losses as there are in the tanks Only respond to the level indicator after the foam has been completely removed.
- WO-A-94/18 301 (Laporte E.S.D.) the use of a strong alkaline, aqueous, highly viscous cleaning agent for cleaning Metal kettles that are used in the food industry are described.
- These cleaning agents contain at least 40% by weight of solids and consist of sodium hydroxide, a polyacrylic acid salt and others Auxiliaries, builders, surfactants and complexing agents.
- DE-A-36 35 357 (Wellhoener) relates to a method for cleaning and Germ reduction in the beverage industry, especially in the brewery, consisting of the following process steps: 1) pre-rinsing with water, 2) Cleaning rinsing, 3) intermediate rinsing with water, 4) disinfection rinsing, 5) Final rinse with fresh water.
- the cleaning rinse and the Disinfection rinsing with an alkali, preferably sodium hydroxide solution an additive is added to the lye, which is a surfactant and optionally Contains complexing agents and solubilizers. This is the process a "lost" CIP process.
- US-A-4,935,065 (Ecolab Inc.) relates to a "stacked" CIP cleaning process for use in the food industry. It will Cleaner concentrates used, the alkali metal hydroxide, active chlorine compounds, Contain acrylic polymers and organic phosphonic acids.
- the invention has for its object an improved method for cleaning of pipelines and containers in the food industry.
- the disadvantages of the "lost" CIP cleaning are to be avoided and thus a same or better cleaning success with less water and Use of detergents, lower energy costs and reduced cleaning and Downtime can be achieved.

- the cleaning agent film or foam runs in containers slower from the surface than the solution in the conventional CIP process, see above that different shear loads occur in the wetting and action phases act on the dirty wall, which also improves cleaning success.
- rheopexes that is to say, are particularly advantageous Viscosity-increasing cleaning agents are used under shear stress.
- the Advantages of this method according to the invention are that the application of the rheopex cleaning solution due to the action of shear forces during application leads to a stable foam or film that slowly liquefies as a result on the one hand the exposure time to the surfaces to be cleaned compared to a large-pored one Foam increases, on the other hand there is an additional mechanical one Cleaning effect that the known film-forming cleaners do not have.
- a rinsing of the surfaces required in prior art methods with hot water can be done but is not necessary as the Cleaning solution light and residue-free with little use of cold water can be removed.

Description
Das vorgehend beschriebene Verfahren wird als "gestapelte" CIP-Reinigung oder "Stapelreinigung" bezeichnet, da hier die Lösungen -gegebenenfalls nach Reinigung durch Membranfiltration- zur Wiederverwendung in den CIP-Tanks "gestapelt" werden. Im Gegensatz dazu werden bei der Variante der "verlorenen" Reinigung die Lösungen am Ende des Reinigungsschrittes in die Kanalisation geleitet und nicht "gestapelt".
- Mit den Reinigungslösungen wird auch der enthaltene Schmutz aus der Reinigung "gestapelt". Bis zu einem gewissen Grad findet eine zunehmende Verschmutzung der Lösungen statt. Nach einer empirisch ermittelten Anzahl von Reinigungen wird daher der Reinigungsmitteltank entleert und neu angsetzt.
- Bei der Stapelreinigung ist die Reinigungsmittelkonzentration im CIP-Tank konstant zu halten. Verluste durch Verdünnung bzw. Verbrauch durch chemische Reaktionen während der Reinigung sind auszugleichen. Hierbei wird im Stand der Technik die Konzentrationsüberwachung im CIP-Tank durch Leitfähigkeitsmessung angewandt. Dies setzt den Einsatz von Reinigungsmitteln mit einer gut ausgeprägten Leitfähigkeit bzw. einer deutlichen Abhängigkeit ihrer Leitfähigkeit von ihrer Konzentration voraus. Dadurch verbietet sich vielfach der Einsatz neutraler Reinigungsmittel.
- Bei der Leitfähigkeitsmessung wird im wesentlichen nur die Basiskomponente des eingesetzten Reinigungsmittels (meist Natriumhydroxid oder bei sauren Reinigern eine Mineralsäure wie Phosphor-, Schwefel- oder Salpetersäure) bestimmt. Man schließt aus deren, über die Leitfähigkeit meßbaren, Konzentration auf die Gesamtkonzentration des Produkts. Dies ist in der Regel auch praktikabel, schließt aber nicht mit Sicherheit aus, daß einzelne Inhaltsstoffe moderner, komplex aufgebauter Reinigungsmittel mehr oder weniger stark verbraucht werden als die Basiskomponente. In einigen Fällen kann diese Unsicherheit nicht toleriert werden und es muß eine aufwendige separate Bestimmung gewisser Einzelkomponenten durchgeführt werden (z.B. Hypochlorit, Peroxide).
- Die oben aufgeführten Nachteile werden ausgeglichen, indem häufig mit höheren Konzentrationen als theoretisch notwendig gearbeitet wird. Außerdem findet ein gewisser Ausgleich durch die im Verhältnis zum Schmutz sehr großen Reinigungsmittelmengen in den CIP-Tanks statt. Dies wirkt sich aber negativ auf die Verfahrensökonomie aus.
- Eine "gestapelte" CIP-Reinigung erfordert eine hohen apparatetechnischen Aufwand für Stapeltanks, Zuleitungen, Ableitungen, Pumpen, Ventile usw.
- Bei einer Reinigung, die bei höherer Temperatur erfolgen soll, muß das gesamte Reinigungsmittel erhitzt werden, das sich in den Rohrleitungen und Tanks wieder abkühlt und nach dem Umlauf wieder auf die gewünschte Betriebstemperatur gebracht werden muß. Auf diese Weise wird unter hohem Energieaufwand das gesamte zu reinigende System mit den Zu- und Ableitungen auf die gewünschte Reinigungstemperatur gebracht.
