The present invention relates to a conveyor dishwasher&#x2014;with at least one final rinse zone with at least one final rinse nozzle for spraying final rinse liquid onto washware, and wherein a metering device associated with the final rinse zone is provided for adding a disinfectant to the final rinse liquid in a metered manner. A sensor device is configured to detect the concentration of disinfectant in the final rinse liquid which is sprayed in the final rinse zone. Furthermore, a control device is configured to compare the value of the concentration of disinfectant which is detected by the sensor device with predefinable concentration values and, in the event of excessively high deviations of the concentration of disinfectant from the predefinable concentration values, to interrupt the dishwashing process or to output a warning signal to an operator.

Conveyor dishwasher having a sensor device for detecting the concentration of disinfectant

A warewasher has at least one treatment system comprising a jet system () with at least one jet for spraying treatment liquid onto the items within at least one treatment zone (), a fresh water system and a control device (), wherein the fresh water system has at least one water feed (), with at least one fresh water inlet () for the introduction of fresh water into the at least one treatment zone () as well as a controllable capacitive deionization unit (), wherein the at least one cell () is designed to be operated in a deionization mode and in at least one further operating mode, wherein the control device () is designed to change the operating mode of the at least one cell () in accordance with at least one operating parameter of the warewasher.

Warewasher and method for operating a warewasher

The invention relates to a conveying apparatus ('&#x2033;) for feeding washware () to at least one conveyor belt () of a commercial conveyor warewasher (), with a conveying system () for conveying the washware (), in particular for feeding trays or tray-like washware (), of cutlery and/or of other washware (). The invention is characterized by an unloading station (&#x2032;&#x2033;) for automatically unloading the washware () from the conveying apparatus (&#x2032;&#x2033;) transversely to the conveying direction of the conveying system (), in which the trays (), with or without cutlery () lying on them, can be oriented on edge and parallel to the transport direction of the conveying system (), so as to be capable of being placed onto a conveyor belt () of the conveyor warewasher. The invention relates, furthermore, to a flight-type warewasher () and to a combination of this warewasher () and of the conveying apparatus (&#x2032;&#x2033;). The invention relates, moreover, to a method for loading a flight-type warewasher (), by means of a conveying apparatus (&#x2032;&#x2033;) and to a preferred use of same for loading a warewasher with trays or tray-like washware ().

Conveying apparatus for feeding washware to a conveyor warewasher

A conveyor dishwasher has at least one wash zone, at least one final rinse zone, and conveyor apparatus. In order to reduce the consumption of disinfection chemical and energy, but to nevertheless maintain a desired final rinse result, the final rinse liquid which is sprayed in the final rinse zone has a metered disinfection chemical, and at least one additional final rinse zone arranged downstream of the final rinse zone provided for spraying fresh water without a disinfection chemical onto the washware to be treated. The at least one additional final rinse zone has an associated collection device for collecting liquid which is sprayed in the additional final rinse zone. Furthermore, a liquid transfer system is provided, it being possible to supply the liquid which is collected in the collection device directly to the wash zone by means of said liquid transfer system.

Conveyor dishwasher and method for operating a conveyor dishwasher

A conveyor warewasher () which having at least one washing zone (), at least one rinsing zone () and at least one drying zone () and also a control device (). In order to achieve an effective cleaning and drying of the washware, along with as low a consumption as possible of resources in terms of water, chemicals and, in particular, energy, there is provision for the control device () to be designed for selecting a previously defined or definable program sequence at least in the at least one drying zone () and for setting the process parameters associated with the selected program sequence automatically as a function of the conveying speed at which the washware is conveyed through the treatment zones () of the conveyor warewasher ().

Conveyor warewasher and method for operating a conveyor warewasher

Conveyor ware washer comprising a water treatment device () for treating sprayed wash liquid in such manner that the treated liquid is of potable quality of water from the microbiological point of view and hence can be used as final rinse liquid or as part of a final rinse liquid.

Conveyor ware washer

Multitank conveyor-type dishwasher () for washing items () to be washed, comprising at least two wash zones () which are arranged in succession in the conveying direction (); a liquid forward-flow apparatus () between in each case two successive wash zones () for transferring liquid between these wash zones () in a forward-flow direction () counter to the conveying direction (); characterized in that a liquid recirculation apparatus () is provided for transferring sprayed liquid of a front wash zone (), as seen in the conveying direction (), into a rear wash zone () which is arranged downstream of the front wash zone (), as seen in the conveying direction (), counter to the forward-flow direction ().

Multitank conveyor-type dishwasher and an operating method for it

A conveyor dishwasher includes a storage tank for holding sprayed final rinse liquid and a controllable liquid transfer device for transferring liquid from the storage tank to at least one wash zone as a function of a liquid demand in at least one of the wash zones.
