This machine is designed to allow the regulation of treatment times from the operator panel through electrically operated solenoid valves on each nozzle, in order to eliminate the limitations typical of normal mechanical rinsers.
In conventional rinsers, in fact, the valves are mechanically operated through cams that are subject to wear, and the only way to vary the injection time of the rinsing fluid is by manually changing the position of these cams.
The electronic rinsers can run single, double or even triple treatment cycles; the treatment times are established on the basis of the dimensions of the containers, the sterilizing product used, and the degree of cleanliness and/or decontamination required.
The advantage of using an electrically operated system, as opposed to a mechanical one, is that of being able to enter a preset injection time for each bottle and of maintaining it constant when the hourly output – and thus the speed of the machine – is varied, with high savings in the consumption of the washing fluids used, as well as elimination of the wear problems typical of mechanical drives. In the case of machines running single treatment cycles, only the spraying time needs to be set, as the rest of the time available is used for the dripping phase.
In the case of the double treatment cycle, on the other hand, it is necessary to set the times of the two separate treatment cycles, to which two separate solenoid valves correspond , and the intermediate dripping time, i.e. that taking place between the injection phases of the two fluids.
The duration of the intermediate dripping time may either be kept constant or varied on the basis of the bottle size, or in proportion to the speed of the machine.
The sequence of the treatment times will, however, always be the same, irrespective of the speed at which the machine is operating.
