Abstract (en)
The invention pertains to industrial washing machines, in particular to single-drum tunnel washers, comprising a device for product-concentration control consisting of a cell capable of measuring a concentration-dependent physical parameter, a device for dosing product into the washing machine, and an electronic control unit which monitors said measuring cell and controls the operation of the dosing device as a function thereof, characterized in that the measuring cell is positioned inside the drum and capable of rotation therewith. Preferably the control unit is such that the product-dosing device is switched off during the emerged position of the cell. By the invention an improved product-concentration control is achieved.
