At this At the moment, if the level in the tank 10 is less than a minimum, it is supplemented by a supply of dye solution coming from a reserve 42, by means of a solenoid valve 43 controlled by a minimum level detector 44.
  • the pump 33 then circulates the liquid in the device 18 to control its color and correct it if necessary, while reheating takes place in the enclosure 14.
  • the circuit of the dye solution actually consists of a first circuit which is closed and which passes through the impregnation chamber 4, and a second circuit which in fact constitutes the return of the liquid of the dewatering chamber 5 at the reservoir 22, from which the regenerated solution is reinjected into the first circuit as required.
