  • Such a bottle washing machine allows a Water saving without the use of biological Wastewater treatment process, precipitation and flocculation plants or the like and thus represents an economical way of saving water. If the Washing machine, however, is only partially utilized, which takes to clean the Bottles actually required amount of water, however, while a constant Amount of fresh water is fed. The water use efficiency therefore decreases at a partial utilization of the plant.
  • the invention is therefore based on the object, a washing machine to propose the greatest possible at different utilization levels Water saving permits.
  • the object is further achieved by a method for cleaning packaging containers, in particular glass and plastic bottles, wherein the containers to be cleaned successively pass through an advance station for pre-cleaning the containers, a liquor bath for intensive cleaning of the containers, and a rinsing station for final cleaning of the containers Rinsing station is divided into several spray zones and the last run through spray zone water is supplied, the water flow from the fresh water spray zone over the further spray zone (s) to the pre-softening station, wherein the number of circulating containers is detected continuously and the amount of sprayed water supplied in the fresh water spraying zone is regulated as a function of the number of containers detected.
  • the measurement of the passage of bottles through the washing machine and corresponding control of the amount of water in the fresh water spray zone allows each optimal adjustment of the required amount of spray water to the current capacity of the washing machine. So can at a partial load The system saves a lot of fresh water.
  • the fresh water supply to the fresh water spray zone so regulated that even in case of failure of the treatment device a Continued operation of the washing machine is guaranteed. That means it will be at one Failure of the fresh water treatment device accordingly more Fresh water from the "line” also regulated, so that the plant without Interruption can continue.
  • the total amount of water is in Dependent on the number of bottles passing through. So is ensured that an interruption of operation of the reprocessing facility, For example, due to a filter change or the like, not to a costly business interruption of the entire plant leads.
  • the invention of the water consumption of a Bottle washer in combination with a downstream rinser This can be significantly reduced, that the running water of the rinser so The bottled washing machine is recycled with this Water is fed.
  • the combination bottle washing machine with rinser will for example, used in the cleaning of PET bottles where shown has that cleaning results with the same amounts of water that commonly used for glass bottles may be insufficient.
  • Cooling device provided to the discharged from the fresh water spray zone, to cool treated or treated water.
  • Cooling can be used in particular beer or fermented carbonic acid.
  • the invention therefore comprises a device for removing water, in particular from the spray zone immediately adjacent to the alkaline bath, for neutralizing this water and for returning the neutralized water to this spray zone.
  • the neutralization device preferably comprises a pH-controlled CO 2 dosing device.
  • the invention can be found in a majority of the market Bottle washing machines retrofitted and used economically, as Reference sizes for common operating conditions are called 10 cubic meters per Hour fresh water requirement, water or waste water costs in the amount of DM 5, -pro Cubic meter, machine running time 2000 hours per year.
  • Figure 2 shows schematically a bottle washing machine according to the present inventions. Elements corresponding to those shown in FIG are marked with the same reference numerals and therefore will not be repeated explained.
  • Bottle counter 56 on, preferably as inductive Flow measuring device is formed.
  • the counter 56 determines the Bottle flow, for example, the number of running through the plant, too cleaning bottles per second.
  • the counter 56 is located in front of the hot water spray zone 28. each other arrangement inside or outside the bottle washing machine, the one Determination of the bottle penetration allowed, however, is also possible.
  • the Measurement result from the counter 56 is the fresh water control device 58 fed, which due to the bottle throughput the required amount of Fresh water is calculated by the spray bars 44 and 46 in the Fresh water spray zone 32 is injected for bottle cleaning.
  • the total amount of fresh water consists of fresh water from the pipe, recirculated, treated fresh water from the disinfection device 38 and cooling device 40 and reused fresh water from the Bottle rinser 60.
  • the controller 58 ensures that the total amount of fresh water injected is always the one for the corresponds to the required bottle throughput required and optimal amount. In in the case when, for example, the workup of the fresh water from the Fresh water spray zone 32 itself or out of the rinser 60 is defective or only one supplies lower amount of water, the controller 58 holds the Total amount of water always constant, so that a shutdown of the Bottle washing machine is avoided. This increases operational safety and economy of the bottle washing machine according to the invention considerably.
