Definitions
- the invention described below is in the field of commercial Purification and relates to a process for the purification of Refillable bottles and similar containers that accept food serve, according to the preamble of claim 1.
- a method of this kind is for example from the document DE -A- 3,205,956 known.
- the reusable containers can be made of a variety of Materials are made, in particular of glass or of plastics, such as polycarbonate (PC), polyvinyl chloride (PVC), polyesters (for example polyethylene terephthalate, PET or polyethylene naphthenate, PEN) and polyethylene (PE).
- PC polycarbonate
- PVC polyvinyl chloride
- PET polyethylene naphthenate
- PE polyethylene
- the containers can be adapted in their shape for a variety of applications be.
- the pre-rinse is often called as Vorweiche and the zone in which the Treatment with the cleaning solution takes place, referred to as lye zone.
- Both for the Pre-rinse, cleaning and rinsing can be several separate zones be present and depending on the purpose are other zones, such as a upstream depletion of the bottles provided.
- the contacting of the bottles with the cleaning fluids can be done differently in each zone and is usually as sprayed or dipping process formed.
- the bottles are when passing through the The system is initially heated slowly in the pre-cleaning area and clearly in the lye area treated at elevated temperature and then again in the following Nachêtzonen cooled.
- This Area comprises at least one zone in which the bottles in dependence of the Bottle material with a cleaning solution at high temperatures of usually be treated at about 60 to 90 ° C. Particularly good cleaning effects are achieved if 1 to 3 alkaline baths are combined with a subsequent lye spraying zone.
- a lye is a cleaning solution in the conventional cleaning process used, the approximately 1 - 3% sodium hydroxide and additives to sequestering agents, surfactants and other cleaning-active components. Only with such highly alkaline So far leaches were believed to be a satisfactory cleaning of the bottles in a short time to reach.
- alkaline proteases are also related to commercial Textile washing process known from DE 44 11 223.
- the present invention has the object to develop an improved method for cleaning bottles, with which the disadvantages of the previously customary methods are avoided as far as possible without To have to accept reductions in the cleaning result.
- the invention therefore provides a method for cleaning reusable bottles and similar containers, which serve to absorb food in which the used Bottles transported in a bottle washing machine through several cleaning zones of which at least one zone of the pre-rinse, at least one subsequent zone the treatment with a cleaning solution at elevated temperature and at least one serve another zone of rinsing with water, wherein the cleaning solution at least an enzyme for enhancing the cleaning performance is added and the enzyme a is highly alkaline protease. It is the use of highly alkaline Proteases alone or together with other enzymes, such as amylases, cellulases, lipases, Oxidoreductases, possible.
- the new method it is surprisingly possible in similar short times as with the conventional high alkaline cleaning liquors an at least equivalent Cleaning result at significantly lower temperatures and significantly lower pH values to reach. In many cases, despite lower drug concentration in the Cleaning liquor even a significantly better cleaning result than conventional achieved highly alkaline cleaning liquors.
- the new process is particularly environmentally friendly. The corrosion of the Bottle surfaces is vanishingly small and due to the low working temperatures In addition, energy is saved.
- enzymes can be according to the invention in addition to the highly alkaline proteases all use those enzymes that have a degrading effect on the to be removed Food residues and impurities have.
- Particularly preferred are the above mentioned enzymes from the group amylases, cellulases, glycosidases, lipases and Oxidoreductases.
- the cleaning process the each to be removed food residues are specifically adapted. So become the Removal of proteinaceous impurities used the highly alkaline proteases, while for starchy impurities, preferably amylases and for the Removal of fatty contaminants lipases can be used.
- the combination Several enzymes for different substrates are recommended in the presence of mixed Impurities.
- Highly alkaline proteases are also known as enzyme preparations in the Commercially available, for example, under the names Savinase®, Esperase®, Durazym®, Maxacal®, Plurafect®, Opticlean® and BLAP®. These preparations contain in addition to the actual active enzyme usually larger amounts of stabilizers and carriers.
- enzymes preferably 0.2 to 100 units per liter of application solution used. Basically, however, in all cases, the necessary Amount of enzyme after the cleaning task to be solved, so that in individual cases the above values were easily exceeded but also fallen short of can be.
- the preparation of the cleaning solution used in the invention from the highly concentrated liquid or powdered enzyme preparations which are offered by different manufacturers.
- the these enzyme preparations admixed with cosolvents, adjuvants or solvents then also become part of the cleaning solution.
- cosolvents, adjuvants or solvents are used for the process according to the invention under the name Savinase®, Maxacal® and BLAP® preparations of highly alkaline proteases.
- the finished, intended to act on the bottles enzyme-containing cleaning solutions generally have a slightly alkaline pH, preferably between about 8 and about 12 and especially between about 8.5 and about 9.5 (measured at 20 ° C) is.
- a pH value well below the value in Maximum activity of the enzyme is chosen especially when it matters To maintain as long as possible the activity of the enzyme in the application solution.
- the pH can be determined by methods known per se, for example by using puffemd acting substances or by a device for automatic dosage of the necessary amount of alkali can be adjusted.
- the cleaning solution at elevated temperature act on the bottles, with significantly lower temperatures than in the past be sufficient cleaning with highly alkaline solutions.
- the exposure temperatures are between about 30 and about 70 ° C, in particular between about 40 and about 55 ° C. Despite these low exposure temperatures are no longer exposure times than conventional cleaning methods necessary to achieve a perfect cleaning result.
- the inventively used enzyme-containing cleaning solutions containing further active ingredients and auxiliaries are mentioned here, in principle, surfactants from all known classes can be used. However, preference is given to nonionic, cationic and amphoteric surfactants which in turn the nonionic surfactants have the greatest importance.
