Definitions

  • the present invention relates to a method for cleaning plants while simultaneously detecting the purity of the plant.
  • CIP clean-in-place cleaning of e.g. Bar or bottling plants
  • aqueous solutions of strong oxidants raises the general problem of detecting the degree of purity of the purified plant.
  • color indicators are added to the solutions in which a color change is observed when leaving the plant, as long as oxidizable (usually organic) impurities are contained therein.
  • permanganate as a strong oxidizing agent which simultaneously provides a color indicator system.
  • DE 10 2006 060 204 A1 has proposed a purification process which comprises recycling the indicator agent for reuse as oxidizing agent.
  • Preferred cleaning and indicator agents are those disclosed in Applicant's above-cited applications.
  • DE 10 2006 060 204 A1 provides a color value of the cleaning composition after leaving the plant to measure and compare with their color value before entry. As soon as the values essentially agree, ie within the limits of a certain tolerance range, the system can be considered sufficiently cleaned. If not, one or more purification steps must be repeated in accordance with paragraph [0020], implying that this is a discontinuous purification process interrupted by the passage of indicator solution through the equipment.
  • This object is achieved by the invention by providing a process for cleaning a plant, comprising passing a cleaning composition comprising at least one oxidizing agent to oxidize impurities, and passing an indicator composition for detecting the state of purity of the plant by observing a color change of the indicator composition, including color values thereof determined at one or more points, but at least after their exit from the plant, and compared with a desired value, wherein the inventive method is characterized in that:
  • a color indicator-containing cleaning composition which serves as an indicator composition at the same time;
  • the color values are determined until a difference AF of 0 is determined, after which the color value last measured is defined as the inherent plant value F A and a maximum tolerable deviation from this value as the target value AF A for cleaning is determined; and f) the cleaning of the plant after its operation is carried out until the difference AF R of two successive color values F R is equal to or less AF A , which indicates the purity of the plant.
  • the base color value of the cleaning composition herein simultaneously referred to as F B prior to entering the system to be cleaned, does not serve as a benchmark for determining the purity of the system. Rather, according to the present invention, so to speak for the "calibration" of the process, the system is first purged with the composition until a constant color value is obtained.
  • the constancy of the plant-specific color value named F A indicates that no more oxidisable impurities are contained in the plant. In contrast to the statements in DE 10 2006 060 204 A1, however, this color value can not at all correspond to the basic value of the composition before it is introduced into the plant.
  • the inventors have surprisingly found that in those plants to which the invention mainly relates, ie dispensing or beverage bottling plants, there is a not inconsiderable reduction of the permanganate during the passing of the plant.
  • the method of the present invention preferably comprises that the inherent plant value F A in step c)
  • the value for F A can be determined several times using different water temperatures, such as those within the natural fluctuation range - during the corresponding season or over the entire calendar year - in order to influence the temperature average out.
  • inaccuracies when mixing the commercially available concentrates for the cleaning composition can be averaged out by varying the initial weight by ⁇ 5% by weight, for example in 1% steps, and determining the respective color values and calculating the average value.
  • these are preferably carried out in the course of the cleaning operations after interim operation of the plant.
  • the color value of the exiting composition can be measured to constancy, so that over time an ever more accurate average for F A is obtained, are taken into account in the temperature, air and concentration fluctuations or influences.
  • step c) for each of the multiple determinations of the inherent plant value F A under the same temperature or concentration conditions, a base color value F B of the composition without passage of the plant can be determined each obtained value for F A , so as to obtain over time an iterating manner an increasingly accurate general correlation between F B and F A.
  • this value for F B does not serve, as in the prior art, as a reference point for the determination of the desired value, but merely represents an alternative or preferably Also, a complement to the multiple determinations described above.
  • the "Ausstoffn" these influences ad hoc.
  • the setpoint AF A which is determined on the basis of the inherent plant value F A initially determined during the "calibration" of the plant and serves as a reference for the measurement during the following cleaning operations, is not particularly limited and may vary depending on several factors vary. These include above all the intended use of the plant itself, for example, whether this is for drinks or other food or not for food, the frequency of cleaning, the costs necessary to achieve a certain purity and the time required for it, but also the reliability of the inherent Asset value F A. The latter depends above all on whether the value is based on multiple determinations, if so, on their number and on which influences were taken into account in the mean value (eg temperature, water quality, etc.).
  • the last difference AF greater than zero before the value constancy is reached can be preset as the desired value AF A , or else a specific percentage deviation from the inherent plant value F A , for example 95% thereof or the like. Since the method according to the invention primarily results in a saving of cleaning composition, a relatively large deviation of F A can sometimes be specified as the setpoint, as long as this is possible, for example, without infringing relevant hygiene regulations.
  • a digital camera is preferably used in accordance with the present invention, and a color comparison software is used to calculate the difference values AF, for example software that converts the colors recorded by the camera into RBG values (if the camera does not have RGB values directly and comparison of these RGB values, for example by a vector subtraction method, wherein the magnitude of the difference vector stands for the respective difference AF.
  • a color comparison software is used to calculate the difference values AF, for example software that converts the colors recorded by the camera into RBG values (if the camera does not have RGB values directly and comparison of these RGB values, for example by a vector subtraction method, wherein the magnitude of the difference vector stands for the respective difference AF.
  • the color indicator-containing cleaning composition in preferred embodiments comprises permanganate as color indicator and at least one further oxidation agent whose oxidation potential is above that of permanganate, as described above, more preferably peroxodisulfate, hypochlorite or a mixture thereof, v. due to the high sensitivity and strong oxidation effect of such systems.
  • permanganate or combinations with oxidizing agent (s) may be used, e.g. e.g. Potassium iodide, dichromate or dichlorophenolindophenol in combination with hydrogen peroxide or ferroin for persulfate.
  • color value is not necessarily an RGB value.
  • the principle of the invention works with all physical data, which allows conclusions on the concentration of manganese ion species in the exiting from the plant cleaning composition - and thus subsequently on the amount of oxidized in the recent passage of the plant impurities - permits. These include, for example, photometrically measured extinction values, the refractive index or else the pH of the cleaning composition emerging from the plant.
  • the principle of the invention works not only with difference values, but also with other relations between two temporally successive color value measurements. Instead of differences, it is also possible, for example, to form quotients of the two last measured values obtained, in which case consistency of the cleaning composition not at a difference value of 0, but at a quotient of 1 vorläge.
  • the target value may be a percentage deviation thereof, eg a value of 0.95 or of 1.05 - depending on whether the color value increases or decreases when approaching the constant inherent plant value F A.

  • the length of the time interval depends significantly on the size of the system and the associated residence time of the composition in the system - from entry to re-exit - from.
  • the residence time may be around 15 minutes, in which case the color value may be determined, for example, every 2 minutes or every 5 minutes.
  • a maximum allowable deviation AF A is defined, which can be reached at the next cleaning of the system after its operation in order to be able to treat the system as sufficiently pure.
  • the size of this setpoint depends on various considerations and circumstances. For example, the last measured difference> 0 can be used as setpoint AF A. This would mean that, according to the method of the invention, flushing of the plant could be stopped a few minutes earlier, saving on material costs (for the cleaning composition), energy and time.
  • a greater difference than AF A is set to increase the savings potential, eg, a difference between F A and that measured prior to the last complete run of the equipment, ie, for example the value measured 15 minutes before the zero difference is reached, or, as already mentioned, a percentage deviation from F A.
  • this is preferably determined several times: be it several times on the same day, for example with different temperatures of the water used to prepare the cleaning composition and / or slightly varying concentrations of the cleaning composition, or on different Days, in addition to the parameters mentioned also include the influences of the ambient air.
