6. CHEMICAL  REPLENISHMENT SYSTEM

When operating a processor which uses chemicals for the continuous production of paper it is
very important that the chemicals within the machine are keep in good working order so as to
provide consistent processing quality. To achieve this consistency we use replenishment
solutions, which are formulated by the chemical manufacturer and injected into the processor
precisely for the area of material being produced. Replenishment of the chemical tanks is done
automatically using infra red sensors located at the entrance to the processor. These sensors
accurately monitor the width of material entering the processor, this information is then used by
the microprocessor (CPU) control software to calculate the surface area for each sheet loaded
into the processor.Each sensor, when covered, will generate a pulse, which is then recorded on
a decoder and counted – the more sensors that are covered then the faster the count. When the
count reaches the programmed value of pulse counts it triggers the start of a replenishment
cycle. During each replenishment cycle the replenishment pumps inject fresh solution from
small storage bottles/tank and into the corresponding ”working” tank solutions for a pre-set time.
