Abstract (en)

An industrial dishwasher includes a mains water load valve (1), a water softener (4) with decalcifying resins, a salt container (15) that receives mains water to form a brine solution that then reaches the softener (4) through a regeneration valve (14), a heater (7) receiving water decalcified by the softener (4), an exchange container (6) arranged between the softener (4) and the heater (7), an evacuation pump (12) connected to the exchange container (6) in such a way as to completely empty it, and a bypass duct (17) connecting the evacuation pump (12) to a drain (11). With this configuration it is possible to regenerate the resins simultaneously with one or more wash cycles, without having to resort to waiting times or complex duplicate water treatment circuits, so that the regeneration is carried out only when necessary and without significantly affecting the exploitation of the machine.
