Definitions
- the invention relates to a method for cleaning bottles, in particular plastic bottles, in bottle cleaning systems.
- reusable bottles for drinks are cleaned in bottle cleaning systems with sodium hydroxide solution hot up to 85 ° C. with the addition of additives.
- the reusable bottles contain a large number of microorganisms, especially in the warm season, when they return empty from customers. Such bottles are often exposed to the favorable temperatures for the growth of the microorganisms for several days or even weeks. This gives yeasts the opportunity to reproduce and ferment the remains of the beverage, and molds form lawns in the bottle.
- the bottles are treated with water (pre-cleaning) and subsequent cleaning in caustic baths with caustic soda solution at about 1.5% and 50 to 85 ° C.
- this cleaning is not sufficient to completely remove the microorganisms and mold.
- complexing agents for. B. EDTA (ethylenediamine tetraacetic acid) and / or NTA (nitrilotriacetate) to add, whereby a satisfactory mold removal is achieved in the case of glass bottles.
- the invention is therefore based on the object in the cleaning of glass bottles and in particular plastic bottles, which preferably consist of polycarbonate, polyethylene naphthalate (PEN) or in particular PET, in bottle cleaning systems a thorough and satisfactory Removal of microorganisms and mold and in particular to achieve a complete detachment of the mold lawn from the plastic surfaces.
- plastic bottles which preferably consist of polycarbonate, polyethylene naphthalate (PEN) or in particular PET, in bottle cleaning systems a thorough and satisfactory Removal of microorganisms and mold and in particular to achieve a complete detachment of the mold lawn from the plastic surfaces.
- Active oxygen is understood to mean oxygen which can be split off from an oxygen carrier in a reactive (atomic) form.
- active oxygen carriers are perborates, percarbonates and in particular hydrogen peroxide.
- the invention is not aimed at disinfection by killing the mold and the microorganisms, but rather at the mechanical detachment and removal of these special contaminants.
- the cleaning agent containing active oxygen can be applied to the bottles or introduced into the bottles in different ways. It is preferable to use spray pipes. It is proposed that the cleaning agent containing active oxygen is sprayed onto and / or into the bottles, in particular during the preliminary cleaning. This achieves an optimal combination of active cleaning oxygen and spray mechanics.
- the cleaning agent which usually contains 0.5 to 5% and in particular 1 to 4% sodium hydroxide solution, 0.001 to 2%, preferably 0.005 to 1.5% and in particular 0 , Contains 1 to 1% active oxygen.
- the cleaning agent can contain surfactants, namely anionic, cationic and / or nonionic surfactants, for example sugar surfactants, which facilitate or improve the detachment of the microorganisms and in particular of the mold lawn.
- surfactants namely anionic, cationic and / or nonionic surfactants, for example sugar surfactants, which facilitate or improve the detachment of the microorganisms and in particular of the mold lawn.
- the detergent contains complexing agents, e.g. B. polyacrylates, tripolyphosphates, organic phosphonates, chelating carboxylates such as citrates, maleates, gluconates, EDTA and / or NTA, and on terpenes and / or on solvents, for. B. alcohols or dimethyl sulfoxide.
- These additional ingredients can be contained separately or in combination in the cleaning agent. These additional ingredients improve the cleaning performance of active oxygen.
- the invention is not restricted to the application of the cleaning agent containing active oxygen to or into the bottles by means of spray pipes. Other options for bringing the cleaning agent into contact with the bottles can also be used. It is proposed in a further embodiment of the invention that the cleaning product containing active oxygen is added to the detergent solution of the bottle washer, in particular by continuously feeding the detergent product into the supply line of the detergent to the bottle washer.
- the concentration of active oxygen in the lye bath should be 0.001 to 2%, preferably 0.005 to 1.5% and in particular 0.1 to 1%.
- the temperature of the cleaning agent should be 40 to 90 ° C, preferably 50 to 80 ° C. These preferred temperature ranges also apply when the cleaning agent containing active oxygen is applied in the spraying process mentioned above.
- the cleaning agent containing active oxygen is allowed to act on the bottles for a period of from 0.5 to 10 minutes, preferably from 1 to 8 minutes and in particular from 2 to 7 minutes. These exposure times apply both to the action of the cleaning agent containing active oxygen in the lye bath and to the application by spraying.
- the cleaning agent preferably contains one or more complexing agents, for example phosphoric acid, tripolyphosphate and / or sodium diphosphate.
- the bottle is passed through several treatment zones in so-called bottle baskets while observing certain treatment times transported.
- the bottle with the opening facing down is treated with a concentrated spray jet.
- the spray with the detergent containing active oxygen can either only in a lye zone, for. B. the alkali I spraying, or in several alkali zones, for. B. with the Lauge-I, Lauge-Il, Lauge-Ill spraying.
- the caustic baths generally contain NaOH and a cleaning additive.
- the cleaning agent based on active oxygen is added.
- there are impurities such as label residues, dirt, glue components and others.
- the cleaning additives are often acidic solutions which, when added to the alkaline cleaning solution, form the corresponding salts, which in turn have an active cleaning effect.
