If the requirement is for perfectly clear material or to make a precise color with recycled flakes, all glue must be removed, while, for some other application, it is sufficient a flake with no dirt and glue residue is not an important parameter.

 

For the purpose of washing and to remove the glue,we did develop our own technology which include a preparation unit and a friction washer where the amount of friction and residence time of flakes can be adjusted by the operator.

This last machine does not require steam or heating bands of any kind to make water hot because it does it by itself, just by the friction created by the rods spinning inside.

Inside the preparation unit and the washer, flakes are kept under chemical solution for a stated period of time.

Material goes then to a rinse-dryer machine just to be sure that all dirt is gone and to remove traces of caustic solution left.
