An important role in the preparation of the materials is played, as the name itself suggests, by the WASHING.
This step is essential in order to grant the elimination of the polluting fractions, just like grime, contaminants, dust, soil coming from or the utilisation or the stocking of the plastics themselves.
Even if other machineries, like floatation tanks or spin dryers, are recognised to play a partial role in washing, the main washing work is performed by the washing machines, both horizontal and vertical hot water ones.
Experience showed over the years that, thanks to peculiar technical improvements of mechanical nature, ITALREC can grant high washing rates by simply using the horizontal cold water machines, with no need to use both hot water and additives, with considerable saves in terms of energy, and raw materials consumption.
Hot water washing, with possible additives, is usually used in particular cases, above all when dealing with PET bottles for completely eliminating labels and glues, as in this sector the cleaning standards required by law are very restrictive, especially when the future application will be in the food market.
