Definitions

  • the present invention relates to a dishwasher, in particular a dishwasher for dishes, glasses, kitchen utensils, medical items, industrial containers, for example in the form of a multi-tank transport dishwasher, for example for commercial dishwashing.
  • a dishwasher for dishes, glasses, kitchen utensils, medical items, industrial containers, for example in the form of a multi-tank transport dishwasher, for example for commercial dishwashing.
  • Dishwashers in the form of Mehrtanktransport Griffmaschinen are well known. These multi-tank transport washing machines of conventional design have a structure and a fluid guide in the manner that the tanks are hydraulically connected to each other by means of a cascaded system. By this type of hydraulic connection, the zones are procedurally dependent on each other and / or influence each other. At the same time these dependencies are not to be influenced or changed during operation, so that these are given by the structural conditions of the machines. In particular, mention should be made in this connection of a predetermined overflow height, from which fluid overflows from a tank located lower in the direction of the fall.
  • Methods are known in which the material to be cleaned is carried out within a treatment zone under a special spraying system which, for example, applies highly concentrated alkaline or highly concentrated acidic liquids to the material to be cleaned.
  • DE 101 27 919 A1 discloses a cleaning process for starch removal.
  • the method comprises one or more alkaline cleaning steps and / or acid cleaning steps, in particular for machine dishwashing in commercial Cleaning steps, in particular for machine dishwashing in commercial dishwashers, in which mainly starch deposits are removable.
  • An alkaline cleaning step is followed by an acidic cleaning step and this acidic cleaning step is followed by an alkaline cleaning step, with the proviso that a total of at least three purification steps take place.
  • DE 102 57 391 A1 also relates to a process for the acidic cleaning of items to be cleaned.
  • a continuous or discontinuous dishwashing which can be used both in single and in multi-tank machines.
  • the material to be cleaned is treated with at least one process step with an acidic and in a further process step with an alkaline cleaning solution.
  • single-chamber dishwashers with a stationary washing process are known, in which the items to be cleaned are treated with a granular rinsing step in one program step.
  • Such granule dishwasher is known for example from WO 9317610.
  • the device disclosed in WO 9317610 comprises a pump for conveying a fluid with or without granules, which is heavier than the liquid.
  • the proposed solution according to the invention is based on the object, in view of the disadvantages of the solutions of the prior art, to provide a dishwasher, in particular a multi-tank conveyor dishwasher, in which a standard special treatment zone between existing treatment zones for the material to be cleaned is integrated.
  • this object is achieved by the features of claim 1, according to which an installation of at least one special treatment zone, for example, takes place after Vorab syndromemzone, or this special treatment zone is after the first washing zone.
  • the special treatment zone is hydraulically connected to the other treatment zones or, alternatively, designed to be partially or completely self-sufficient. This may mean that no cleaning solution is conducted from an upstream and / or downstream zone into the special treatment zone and / or that no cleaning solution from the special treatment zone in one of these upstream or subsequent zones is performed and / or that the wastewater from the special treatment zone run separately and / or disposed of separately.
  • This "isolation" of the at least one special treatment zone is made possible by the fact that the standard tanks of Mehrtanktransporterpülmaschine are not connected hydraulically via cascades, but for example via a pump system, such as Meiko M-filter pumps, which are already well established in the market
  • transport means used as part of the multi-tank transport dishwasher is a circulating endless link belt, which is made, for example, of plastic material will be produced.
  • the conveyor belt for example in the form of an endlessly circulating finger band, can either be guided completely in one strand through the standard treatment zones and through the special treatment zone proposed according to the invention.
  • a first endless circulation transport means takes over the transport of the cleaning material in the first section of a cleaning zone
  • a second transport promotes the material to be cleaned through the special treatment zone
  • a third Transport is provided, which promotes the cleaning material through the remaining parts of the cleaning zone or the multi-tank transport dishwasher.
  • the at least one special treatment zone is designed as a granular purging zone, for example, an empty zone
  • the actual Granulat Vietnamesezone ie the special treatment zone
  • the Granulat Jewishzone another empty zone.
  • the special treatment zone for example, designed as a ⁇ Granulat Vietnamesezone, boasts its own circulation pump and a special washing system.
  • the treatment zone which is designed in particular as a granulation zone, has a specially designed collecting and filling system in order to reintroduce the cleaning granules into the fluid circuit. Whether the granules are added before or after the circulating pump, may initially stand there. It is conceivable that the supply of the cleaning granules after the circulation pump has positive effects on the durability of the granules, which is due to the fact that the granules do not come into contact with the impeller of the pump.
  • the mode of operation of the multi-tank transport dishwasher with special treatment zone proposed according to the invention is as follows:
  • the material to be cleaned is placed at the inlet of the multi-tank transport dishwasher on the endless trained example of plastic transport in the form of an endless finger belt and then runs into the dishwasher.
  • a first zone coarse food particles are rinsed off and the entire dirt is soaked with cleaning liquid.
  • a treatment of the cleaning material taking place in the special treatment zone comprises, for example, the following steps:
  • the special treatment may further comprise a treatment of the cleaning product with an enzymatic cleaner, which requires a neutral adjustment of the cleaning liquid.
  • the cleaning material in the context of special treatment with an alcoholic cleaning fluid or e.g. to treat with salt water.
  • the special treatment zone downstream of the pre-evacuation zone would offer the possibility of irradiating the material to be cleaned with pellets of ice or treating the material to be cleaned with cleaning granules.
  • the mode of operation of the special treatment zone which can be designed, for example, as a granulate rinsing zone, is as follows:
  • the granules can be made, for example, of plastic with a density which is significantly greater than 1.0 g / cm 3 , for example 1.4 g / cm 3 ; or even heavier. This is achieved, for example, by adding barium sulfate, for example, to a plastic material such as PP, mineral additives, for example, before the granules are produced. Alternatively, plastics with a corresponding density, for example POM, can also be used.
  • the mass of the individual granules used allows an increased pulse, so that their impact on the material to be cleaned, a reinforcement of a dirt-dissolving or residue-removing effect against a cleaning liquid can be achieved only on a water basis.
  • Granulat Vietnamesezone special treatment zone to be cleaned passes through other zones of Mehrtanktransport Vietnamesemaschine, which are configured in a known manner, for example, several cleaning zones, a Pumpenklar Cypruszone, a fresh water rinse and a drying zone.
  • the cleaning granules are kept in the special treatment zone designed as a granular rinsing zone and a carryover to other cleaning zones is prevented.
  • a discharge of cleaning granules from the special treatment zone is to be avoided, since otherwise this would be lost for use in the Granulat Vietnamesezone and would be permanently replaced again.
  • the granules may possibly clog spray nozzles of adjacent cleaning zones and clog with them.
  • the empty zones upstream or downstream of the special treatment zone make it possible to increase the soaking effect on the persistent soiling or caking.
  • This exemplary arrangement would result in a contact time of the granular rinsing zone of 60 seconds on the material to be cleaned, for example, by means of a transport speed of the items to be cleaned by the multi-tank transport dishwasher of 0.8 m per minute.
  • the contact time can be doubled without any problems, d. H. be extended to 120 seconds.
  • the multi-tank transport dishwasher can be configured with a recognition for the items to be cleaned, such as a camera with image recognition, at the inlet of the dishwasher, so that the special treatment zone can only be turned on as needed; just then, especially when heavily soiled dishes, such as casserole dishes with baked starch residues, are to be cleaned.
  • the special treatment zone can also be activated manually, eg by the operating personnel, and switched off again. Similarly, a shutdown after a stored time in the control is conceivable.
  • the special treatment zone is designed as an acid zone
  • the effluents of this zone waste water other alkaline zones could be fed, so that optionally results in a neutralization of the waste water of the multi-tank conveyor dishwasher.
  • the cleaning fluid in the at least one special treatment zone can be exchanged or completely renewed independently of the filling of the remaining zones.
  • a special, additional to be performed treatment to be cleaned Good that is independent of the rest, to be performed by default cleaning process, the continuous operation of Mehrtanktransport Vietnamesemaschine and the associated economic advantage can be obtained.
  • the cleaning solution, which is used in the special treatment zone can be disposed of separately, as well as the wastewater produced in it.
  • the cleaning process and the treatment sequence in the rinsing zones provided by default in the multi-tank transport dishwasher remain unaffected by the process in the special treatment zone, whether this is designed as a granular rinsing zone or is designed as an acid treatment zone.
