Definitions
- the invention relates to a method for assessing and ensuring the thermal hygiene effect on items to be washed in a dishwasher during the cleaning process.
- Multi-tank dishwashers are also used today in the commercial sector, in which the material to be cleaned is transported by means of a conveyor through the various zones of the dishwasher.
- Multi-tank dishwashers generally comprise at least one rinse zone, at least one rinse zone and optionally a drying zone.
- Multi-tank dishwashers, in which the items to be cleaned through various treatment zones are usually designed as a belt transport or basket transport machines. Both versions have in common that the items to be washed are transported by the means of transport continuously through the individual treatment zones.
- the individual treatment zones are usually designed as chambers which comprise openings in the transport direction of the conveying device, through which the material to be cleaned is transported by means of the conveying device.
- the rinse water storage tank of the rinse zone is filled with fresh water and heated to the preset rinse tank temperature. Furthermore, detergent is added to the rinse water. If several rinsing zones are arranged one behind the other, this applies analogously.
- the rinsing zone usually has a rinsing water circulation pump, which draws rinsing water from the rinsing water storage tank and sprays onto the items to be washed via a spraying system assigned to the rinsing zone in order to remove the dirt adhering to the items to be washed. Subsequently, the rinse water flows back together with the rinsed dirt back into the rinse water storage tank.
- the rinsed dirt is removed from the rinse water by a sieve system.
- detergent and soil residue levels which are loosely on the items to be washed, are rinsed off by means of hot fresh water, which is sprayed with a corresponding spray system.
- the post-rinse water is collected after the first use in a pump clear-circulation tank and sprayed again by means of a pump and a further spray system over the material to be cleaned. This process step takes place in time before rinsing the material to be cleaned with fresh water.
- the fresh water or the clear rinsing water is then partly supplied to the Spulwasservorrats- tank to dilute the there located in Spülwasservorratstank debris Then, the material to be cleaned is transported to the optional subsequent drying zone in which the Spulgut is dried
- the process factors purifier concentration, contact time of the material to be cleaned from the first contact with the rinse water of the first rinse zone to leave the final rinse, the mechanics of the spray systems or sprays in the rinse zones and the temperatures in the individual rinse zones are crucial.
- Methods for detecting the same are known for the process parameters of cleaner concentration, contact of the product to be cleaned with the rinsing water of the first rinsing zone until it leaves the final rinse zone and the mechanism in the rinsing zone.
- the contact time is determined by the transport speed of the conveyor and the washing mechanism is determined by the pressure of the circulation pump and the execution of the nozzles of the spray system in the respective rinsing zone
- the temperature of the rinsing water in the individual Treatment zones is detected by temperature sensors.
- the temperature reached on the surface of the material to be cleaned is not identical with the rinse water temperature.
- precisely this temperature which is achieved on the surface of the material to be cleaned in the individual treatment zones, as well as the time over which these temperatures act on the material to be cleaned, is of decisive importance for the reduction of bacteria on the surface of the material to be cleaned Influence.
- the action of a certain temperature on the surface of the material to be cleaned for a certain time is or may be referred to as a heat equivalent.
- the relationship of temperature and time to germ reduction is, among other things, the basis of regulations and standards intended to ensure the cleaning effect in winding machines. Based on tests carried out on multi-tank dishwashers, with the aim of defining the process parameters in which a In addition, with the DIN 10510 C.3 for Germany, a method was adopted which gives a recommendation with regard to temperature, detergent concentration and duration between the first contact of the material to be cleaned with the rinsing liquid of the first rinsing zone until it leaves the rinsing zone with which then this multi-chamber dishwasher is to be operated in the individual process zones in order to achieve the required germ reduction during operation of the customer.
- the basis of this standard is the microbial reduction of defined soiled test specimens after the cleaning process via so-called Abklatschuntersuchungen.
- the test germ or organism used in this test is E. faecium ATCC 6057.
- the hygienic safety of multi-tank dishwashers at the end user is checked by means of a follow-up examination and the determination of the number of bacteria in the rinsing water of the last rinsing tank.
- a disadvantage is the fact that the examination of germ reduction locally at the customer can be carried out according to this standard only with great effort.
- Another disadvantage of this standard is the fact that the same germ reduction z B even with a shorter contact time, but at higher temperatures in the individual treatment zones could be achieved. However, this standard does not allow this.
- the temperatures are recorded during the cleaning process. From the temperature profile during the transport of the items to be washed by the multi-tank winding machine, the heat equivalents acting on the plate over the entire cleaning process are determined on the basis of the above-mentioned table. This check is for three - A -
- a disadvantage of the operation of the winder is the fact that from the temperatures of the rinse water of the individual treatment zones must be closed to the heat equivalent acting on the dishes in the rinsing process and not the actual heat equivalents applied to the dishes are determined
- prEN ISO 15883-1 describes a method which also uses the relationship between germ reduction and temperature over time to assess the effect on hygiene. This relationship is referred to as the Ao value and is also tabulated Form written down or calculated from a mathematical formula.
- the Ao value is described in detail in Appendix A of this standard and is defined as the time equivalent in seconds at 80 0 C at which a given disinfecting effect is exercised, and corresponds mutatis mutandis to the heat equivalent of the NSF3 standard, but based on another test germ , The test organism used in this method is Enterococcus Faetium.
- an at least achievable Ao value is predetermined at each point in the spdl chamber of the washer-disinfector. However, this process has not yet been used to assess commercial dishwashers in Europe.
- EP 1 196 650 B1 relates to a method for monitoring a washing process.
- an independent wireless monitoring device is applied to a conveyor belt of an industrial dishwasher and moved with this.
- the measured data are recorded in a monitoring unit.
- the temperatures at the individual rinsing zones can be recorded and evaluated at a later time. Thereafter, a determination of the heat equivalents, which are transmitted to the material to be cleaned, could be made on the basis of the determined temperature values.
- the difference with temperature recording in the NSF3 standard process is that the temperature sensing is wireless.
- the device known from EP 1 196 650 B1 is similar to the test method according to the NSF3 standard only for controlling the process temperatures, is not evaluated by the control of the dishwasher and thus does not serve for direct control of the process parameters of the Mehrtankspulmaschine.
- DE 196 08 036 C5 shows, the dependence of Nachspul water quantity of the transport speed of the conveyor of Mehrtank Vietnamesemaschine set directly in dependence. A dependency of the amount of clear rinse water and the heat equivalents actually transferred to the items to be washed is not discussed in more detail in DE 196 08 036 C5.
- the object of the present invention is to provide a method for detecting the thermal equivalents transferred to the material to be cleaned in order to eliminate the above-described disadvantages of the solutions according to the prior art and at the same time to increase the process reliability with regard to the thermal hygiene effect.
- step d) depending on the result of the process according to step c) performed comparison of the heat inputs, the transport speed of the items to be washed by the
- step c) following the method proposed according to the invention, it is determined whether the heat input into the at least one of the treatment zones corresponds to the predetermined heat input, exceeds the predetermined heat input, or falls below the predetermined heat input.
- z. B the transport speed of the items to be washed, which serves as a control variable for the control loop, increased, so that the transported through the respective treatment zone of the multi-tank dishwasher ware is transported faster through the zone.
- a temperature decrease in at least one heated zone of the treatment zones or the temperature in a subsequent treatment zone can be lowered to compensate for the increased heat input in the previous treatment zone
- Temperature m can be lowered in a already passed from the Spulgut treatment zone, which allows energy savings in terms of heating the at least one treatment zone and allows a predictive driving style of Mehrtankspulmaschine that is highly energy efficient. If, on the other hand, it is determined that the predetermined heat input is undershot by the heat input in at least one of the treatment zones, the transport speed of the items to be washed by the at least one relevant treatment zone can be reduced via the machine control.
- the detection of the temperature in the at least one treatment zone of the multi-tank dishwasher can be effected by a sensor which is moved during the transport of the items to be washed by the multi-tank dishwasher and z B to a the Wicking receiving basket, on a continuous material through the Mehrtank Vietnamesemaschine the conveyor belt or the like, and transmits the temperature values Oi n prevailing in the respective continuous treatment zones to the machine control.
- the detection of the temperature in the individual treatment zones of Mehrtank Vietnamesemaschine also by the zones stationary associated sensors can be detected and transmitted to the machine control, in the calculation of the actual heat input in It is irrelevant whether the sensor detecting the individual temperatures of the at least one treatment zone is moved or stationary, the circumstance that the stationarily arranged or moved sensor determines the temperatures detected individually in the at least one treatment zone is decisive the machine control of Mehrtank Vietnamesemaschine transmitted.
- the machine control can be calculated in the calculation of the actual heat input in one or more of the traversed or still to be processed treatment zones depending on the traversed in the relevant treatment zone transport path of the Spulgutes including the transport speed of the heat input.
- the heat input actually carried out in the relevant treatment zone can also be determined in the machine control as a function of the residence time of the ware in the respective treatment zone
- the specified heat input into the overall system multi-tank dishwasher to ensure the hygiene effect for example, either by heat equivalents HUE of the NSF3 standard or by the A 0 values of EN 15883-1 Annex 1 or any defined relation between the temperature ö and corresponding heat equivalents stored.
- the transport speed of the wash ware can be temporarily set to 0 by one of the treatment zones, i. H. the transport of the Spulgutes be stopped by the Mehrtank Anlagenmaschine. This results in a longer residence time of the ware in at least one of the treatment zones of the multi-tank dishwasher, so that the actual heat input increases
- a fresh water stream fed in a fresh water clear-wind zone for example, increases or increases in terms of its volume flow can be reduced or the temperature of the registered in the Frischwasserklarspulzone amount of water can be varied in order to influence the actual heat input.
- the volume flow circulated within a pump rinsing zone of a multi-tank dishwasher can also be increased or reduced.
- the drying zone of the multi-tank dishwasher which is usually downstream of the Frischbergklarspulzone or Pumpenklar Hugheszone, for varying, ie increase or decrease of the actual heat input there, the drying air inflated on the items to be washed respect to their temperature can be varied, ie their temperature is increased or lowered.
- an additional heat input into at least one of the treatment zones of the multi-tank coiling machine is possible by means of an infrared radiator, which is preferably arranged behind or behind a drying zone in or in the transport direction of the items to be washed.
- an infrared radiator which is preferably arranged behind or behind a drying zone in or in the transport direction of the items to be washed.
- an adaptation of the temperature in a treatment zone already passed by the material to be spilled can be carried out and / or a prognosis of the heat input based on an extrapolation of the temperature values in the transport direction of the Washware seen subsequent treatment zones done.
