<p>The invention relates to a method of cleaning the exterior of reusable bottles in particular a glass bottle with the object of achieving a recycling percentage close to 100 of the bottles using a natural cleansing medium together with pressurized air. The natural cleansing medium is NaHCO3 in granules of a certain size, which injected in the air stream in the right dosage, explodes when reaching the label (11) on the bottle and is removed leaving the surface of the bottle smooth and undamaged. The cleaning station (2) is built on the conveyor belt (1) already existing in the known bottle washing plants and situated before the washing machine. The bottle (6) is fixed in top and bottom and NaHCO3 is blasted on the bottle in an air blast chamber (4) through one or several nozzles (5) connected with a NaHCO3 blasting machine. The air blasting chamber is under vacuum for sucking away the residue of glue and labels as well as of the cleansing medium which is transported off into a waste bin outside the cleaning station. When undertaking the exterior cleaning of the bottle before it enters the washing machine will reduce the consumption of water and as the use of chemicals can be eliminated, the result will be a cleaner waste water into the sewer.</p> |
