Definitions

  • This invention relates to a machine dishwashing process for cleaning tableware or other surfaces soiled with food remains. More particularly, the object of the invention is to improve the continuous or discontinuous process of machine dishwashing which may be carried out both in single-tank and in multi-tank machines.
  • the wash liquor usually consists of water with a temperature of about 50°C to 65°C to which a cleaner is added.
  • detergents in powder or liquid form for example, are added to the water, so that about 0.1 to 0.3% by weight of active washing substances are present in the cleaning solution.
  • the resulting wash liquor is usually sprayed on to the articles to be cleaned through differently arranged nozzles.
  • the soil on the tableware is thus removed or at least swollen or softened and partially dissolved.
  • the wash liquor is rinsed off.
  • the rinse water usually consists of fresh water and a rinse agent, which generally ensures that only a very thin film of water is left on the tableware and can drain off or evaporate in following drying zones.
  • institutional dishwashing machines usually comprise several tanks arranged in succession, from which rinse and wash liquor is sprayed onto the tableware to be cleaned as it passes through the machine.
  • the tanks are generally arranged on the cascade principle, the rinse and wash liquor passing successively through the tanks from the outlet end to the inlet end of the tableware.
  • Fresh water is generally fed into the machines at the outlet end.
  • the required amount of detergent is dosed into at least one wash tank also known as the dosing tank.
  • the dosing of detergent normally takes place automatically depending on the conductivity or the pH of the wash liquor or optionally by means of a dosing pump controlled by a timer or clock. Several components may also be separately dosed.
  • a basic lye solution based on an aqueous alkali metal hydroxide solution may be introduced first.
  • one or more additives may be added to this basic solution. Normally, the dosage of these additives is either proportional to the addition of the basic lye or is controlled by a timer. If desired, the additives may be dosed according to the advance cycle of the chain carrying the tableware to be washed through the machine. In addition, additives can also be dosed or the additive concentration increased by determining the amount of additive in the basic lye by sensory detection of a tracer present in the additive.
  • EP 282 214 attempts to solve the problem by spraying a highly concentrated cleaning formulation onto the soiled articles, followed by a contact phase, after which the cleaning solution and soil are removed in one or more following steps.
  • EP 282 214 mentions reducing pollution of the wastewater as an essential aim of the invention.
  • an essential aspect of the pollution of wastewater was not taken into account.
  • the wastewater In the treatment of wastewater, it is usually imperative for the wastewater to have a certain pH before or during treatment in corresponding treatment plants. This pH is generally close to the neutral point of water according to the nature of the treatment.
  • there are even country-specific wastewater regulations which stipulate a particular pH for wastewater. All this means is that more chemicals have to added to neutralize strongly acidic or strongly alkaline wastewater before further treatment.
  • EP 282 214 takes no account at all of this problem.
  • alkaline detergents are mentioned and recommended.
  • the cleaning agents to be used are explicitly discussed.
  • column 3, line 24 it is disclosed that, for example, alternately spraying with high alkalinity and then with lower alkalinity could have advantages.
  • oxidizing agents such as hypochlorite
  • water treatment substances such as NTA for example
  • various substances are known to improve penetration and to help soften and remove the soil.
  • EP 282 214 A1 states that a basic formulation will typically contain an alkalinity source and a sequestrant source. On the bases of formulations such as these, it is possible to cater for special problems such as, for example, tea stains or other residues which may be found on tableware.
  • the problem addressed by the present invention was to provide a process which, firstly, would solve the cleaning problem posed by EP 282 214 without the need for thorough cleaning.
  • the problem addressed by the invention was to minimize the time and effort involved in neutralization before or during treatment in wastewater treatment plants. At the same time, care would be taken where possible to ensure that applicational requirements with regard to equipment and other factors would be satisfied.
  • the present invention relates to a process for continuous or discontinuous machine dishwashing, in which the tableware is treated at least in one process step with an acidic cleaning solution and, in another process step, with an alkaline cleaning solution, comprising the steps of a) applying an acidic aqueous cleaning solution to the at least partly soiled tableware and b) removing said acidic aqueous cleaning solution and the soil in one or more following steps, the at least one alkaline treatment taking place before and/or after the acidic treatment and the alkaline and at least one acidic aqueous cleaning solution at least partially neutralizing one another.
  • the acidic cleaning solution mentioned contains one or more acids selected from the mineral and/or organic acids.
  • at least one acid is present which is selected from sulfuric acid, nitric acid, phosphoric acid, formic acid, acetic acid, propanoic acid, glycolic acid, citric acid, maleic acid, lactic acid, gluconic acid, alkanesulfonic acid, amidosulfonic acid, succinic acid, glutaric acid, adipic acid, phosphonic acids, polyacrylic acids or mixtures thereof and, in a most particularly embodiment, from formic acid, glycolic acid, gluconic acid, amidosulfonic acid or the alkanesulfonic acids, more particularly methanesulfonic acid or mixtures thereof.
  • the aqueous acidic cleaning solution to be sprayed on in accordance with the invention preferably contains as further components a corrosion inhibitor and/or a typical complexing agent which, in a particularly preferred embodiment, is selected from the phosphonic acids, more particularly dioctyl phosphonic acid.
  • the acidic cleaning solution contains between 0.01 and 10% by weight of one or more detersive substances, based on the cleaning solution.
  • the acidic cleaning solution mentioned contains less than 0.9% by weight, more particularly less than 0.8% by weight and, in a most particularly preferred embodiment, less than 0.5% by weight of one or more detersive substances, based on the cleaning solution. The exact conditions also depend on the more precise practical circumstances and the performance requirements the process is expected to meet.
  • weakly acidic cleaning solutions with an active acid content of less than 0.9% by weight, preferably less than 0.8% by weight and more particularly less than 0.5% by weight.
  • weakly acidic cleaning solutions may also have the advantage that the consumption of the lye baths into which the possibly acidic solution is carried over is not too high.
  • the acidic aqueous cleaning solution is allowed to act on the tableware and the soil for a certain contact time (during which spraying stops), the contact time preferably being 2 to 100 seconds, more preferably 5 to 100 seconds and most preferably 8 to 25 seconds.
  • the tableware is not intentionally sprayed during the contact time.
  • the acidic aqueous cleaning solution is sprayed onto the tableware as a fine, gentle mist-like liquid spray.
  • the acidic cleaning solution is applied to the tableware as foam.
  • the cleaning solution could also be applied to the tableware in droplet form or by the Ecolab process known commercially as thin film cleaning (TFC).
  • the acidic cleaning solution is preferably applied before the final rinse cycle or the final rinse zone.
  • Another preferred embodiment of the process according to the invention is characterized in that the treatment with the acidic cleaning solution is preceded by an alkaline treatment of the tableware of which the pH is a particularly preferred embodiment is above 10. In another preferred embodiment, the treatment with the acidic cleaning solution is followed by an alkaline treatment of the tableware. In a most particularly preferred embodiment, however, the tableware is subjected in all to at least three cleaning steps, the treatment with the acidic cleaning solution being preceded and followed by an alkaline treatment of the tableware.
  • the alkaline step taking place earlier in the process sequence - in a particularly preferred embodiment - has a lower pH than the alkaline step taking place later in the process sequence. This is advantageous in order to minimize consumption in an acidic step taking place between the two alkaline steps mentioned.
  • the tableware comes into contact with one or more aqueous cleaning solutions containing between 0.1 and 4% by weight of an alkali carrier, preferably a hydroxide selected from sodium hydroxide, potassium hydroxide or mixtures thereof.
  • an alkali carrier preferably a hydroxide selected from sodium hydroxide, potassium hydroxide or mixtures thereof.
  • alkali carriers - in addition to or instead of hydroxides selected from sodium and potassium hydroxide - include, for example, alkali metal silicates, ethanolamines, such as triethanolamine, diethanolamine and monoethanolamine, and also alkali metal carbonates of an alkali carrier, preferably a hydroxide selected from sodium or potassium hydroxide.
  • alkali carriers may of course also be used because it is principally a matter of increasing the pH.
  • the present invention also relates to an institutional dishwashing machine comprising several tanks which are arranged adjacent one another in known manner on the cascade principle and from which rinse or wash liquor is sprayed onto the tableware and then drains back into the tanks, the tanks intended for one or more acidic cleaning steps in the operation of the process according to the invention being made of acid- resistant material and/or lined with acid-resistant material.
  • the present invention relates to a single-tank washing machine, for example a domestic dishwasher, which can be used in a process according to the invention and which is made of and/or lined with acid-resistant material, more particularly in the places where it comes in to contact with acidic cleaning solutions.
  • the process of the invention has the further advantage that mineralic deposits on glass and dishes, like lime deposits, which are soluble in acidic solution are removed.

  • Table 2 shows the cleaning results dependant from the different pH- values in the different bars.
  • Example 3 pH-relation between the first and third tank of Meiko GSM To find the best pH-relation from the first and the third tank for the Meiko GSM, a test with two Krefft ® single-tank dishwasher was performed. In the first machine a pH was adjusted with NaOH, a second pH was adjusted in the second Krefft ® dishwashing machine. The water was softened with pH of 9,8 and the temperature was 60° C in both machines. The first step was one minute cleaning followed by a spraying step with a 1 % phosphoric acid and a contact time of 30 seconds and an additional cleaning step of two minutes. Results are shown in the following table 4.
