Abstract (en)

[origin: EP1905339A1] An industrial dishwasher includes a softener (2) with decalcifying resins through which the water coming from the network reaches a break tank (3), connected to the wash tank (9) of the dishwasher, and through said break tank (3) reaches a heater (4) that feeds rinse sprinklers (8) that spray it in the wash tank (9) where it is then collected in a sump (13), the break tank (3) being provided with an expansion chamber (Y), interposed between the inlet of the water coming from the softener (2) and the outlet toward the heater (4), provided with an outlet that connects it directly to the sump (13) through a pipe (B) that bypasses the heater (4), the flow through the bypass pipe (B) being controlled by a valve (12). In this way, it is possible to carry out the regeneration of the decalcifying resins of the softener (2) simultaneously with a wash cycle, without having to resort to pause periods or to complicated double water treatment circuits, whereby the regeneration is carried out only when required and without significantly affecting the exploitation of the machine.
