New Amut de-labeler machine

The machine allowing to overcome the problem of the labels detachment from PET bottles

AMUT has recently launched its new de-labeler, the machine allowing to overcome the problem of the labels detachment from PET bottles, particularly referring to the so called heat-shrinkable “sleeves”, which cover the whole bottle and make it useless for recycling: this is the DLB , articulated on two models depending on the customer needs, with a continuous working process and the warranty of almost total recovery of both bottles and labels.

Benefits

Recovery of PET bottles with PVC or PETG sleeves label;
Almost total detachment of the labels: with a flow of 100% of bottles with sleeves we can achieve detachment results more than 80%;
Continuous process;
Settable treatment residence time, although the continuous process;
Integrity of bottles and necks, to allow the use of downstream detectors and prevent good material loss;
Recovery and valorization of the dry labels, reducing disposal costs;
Polymer and colour recognition efficiency by electronic detectors;
Greater PET flakes purity

Functioning

The labels are removed dry, thanks to the considerable friction performed by the machine moving on their surface.
The flow of bottles is treated with a continuous process. An appropriate residence time in the machine ensures high efficiency of separation, integrity of bottle and necks.
The bottles are fed with a conveyor belt and, after treatment, discharged continuously with a screw feeder extractor.
The tattered labels are collected in a underlying hopper, extracted with a belt and conveyed to a compacting press or a container.
The perfect separation of any remaining free labels from bottles can take place downstream the machine through an air system or a ballistic sieve.

Types And Applications

There are two types of de-labeler:

- the first one is for high flow rates (DLB 60 and DLB 30) suitable to treat the whole flow of bottles at the beginning of the washing line

- the other one to be installed downstream the detectors (DLB 10) to treat their rejected bottles only or those ones taken reduced at the beginning of the line.
