These bottle washers have a double-step label removal. In the first step, after about 40% of the total soaking time, sub-sprays remove the loose labels and the caustic flux with the floating labels is guided directly to the outload filtering conveyor extending across the machine.
In the second step, at the end of the soaking time, many sprays hit the bottles everywhere and totally remove the labels.
The caustic solution with labels is guided directly toward the revolving filtering conveyor and a rotating brush removes the labels and residuals which are sticking on it. In order to guarantee a good efficiency of this system in the long period, the nozzles are easily extractable to make a perfect internal caustic. |
