The invention also proposes a cleaning system which comprises the modular system, and further proposes a method for cleaning washware.

A flight-type dishwasher or rack conveyor dishwasher has a conveyor apparatus (20) for conveying washware through individual treatment zones (11, 12, 13, 14, 15) of the conveyor dishwasher (1). The conveyor dishwasher (1) has a detection system (30) designed to detect the presence of washware or a washware carrier (7) in a predefined region (A) at an inlet (10) or at a feed (16) of the conveyor dishwasher (1). A control device (50) is designed to actuate the conveyor apparatus (20) such that the conveyor apparatus (20) is activated when washware or a washware carrier (7) is detected in the region (A) at the inlet (10) or feed (16) of the conveyor dishwasher (1), and that the conveyor apparatus (20) is deactivated when no washware or no washware carrier (7) is detected in the region (A) at the inlet (10) or feed (16) of the conveyor dishwasher (1).

A dishwasher (1), in particular for a coffee shop and/or for a fast-food restaurant, for cleaning washware, in particular and preferably exclusively washware provided by the coffee shop and/or fast-food restaurant, wherein the dishwasher (1) is associated with an input or insertion region (2) adapted in particular as a return device and in particular adapted as a return machine for reusable washware items (100), and a transport device (3) for transporting the washware from the input or insertion region (2) to a treatment region (4) of the dishwasher (1) and from there to an output or removal region (10) of the dishwasher (1), the treatment region (4) of the dishwasher (1) having a washing and rinsing system (5) for washing and rinsing the washware and optionally, a drying system (6) for drying the rinsed washware, the drying system located downstream when viewed in the transport direction of the washware.

A warewash machine includes a sump for collecting hot cleaning water that is recirculated in the chamber during cleaning, a drain path for draining cleaning water from the sump and a fresh water input line including at least a fresh water input that receives fresh water. A waste water heat recovery arrangement includes a plurality of heat exchange compartments arranged in series flow communication and forming part of the drain path. A waste water input is associated with a first of the heat exchange compartments and a waste water output associated with a last of the heat exchange compartments. Waste water at least partially fills each of the heat exchange compartments. At least part of the fresh water input line passes through each of the heat exchange compartments. Heat from waste water is transferred to fresh water in the drain line within each heat exchange compartment.

A dishwasher (2.1, 2.2) has at least one wash system for spraying wash liquid and at least one final-rinse system for spraying final-rinse liquid, wherein a control device (50) is provided for actuating the at least one wash system and/or the at least one final-rinse system in accordance with a predefined execution program. To save on resources during operation, and meet the requirements for hygienic operation, which are defined in hygiene guidelines applicable locally (in a territorially delimited manner) at least a first execution program is stored in the control device (50), the execution program created taking into account requirements for hygienic operation which are applicable in a first territorial region, and at least a second execution program is stored in the control device (50), the second execution program created taking into account requirements for hygienic operation which are applicable in a second territorial region.

A warewasher includes a liquid recirculation system for spraying wares with wash liquid from a collecting tank. The warewasher includes a filter arrangement for capturing food debris in a wash spray before the wash spray reaches the wares being cleaned.

The invention relates to a conveying apparatus (200, 200, 200, 200) for feeding washware (100, 101) to at least one conveyor belt (50, 51, 52) of a commercial conveyor warewasher (1), with a conveying system (201) for conveying the washware (100, 101), in particular for feeding trays or tray-like washware (100), of cutlery and/or of other washware (101). The invention is characterized by an unloading station (202, 202, 202, 202) for automatically unloading the washware (100, 101) from the conveying apparatus (200, 200, 200, 200) transversely to the conveying direction of the conveying system (201), in which the trays (100), with or without cutlery (103) lying on them, can be oriented on edge and parallel to the transport direction of the conveying system (201), so as to be capable of being placed onto a conveyor belt (50) of the conveyor warewasher. The invention relates, furthermore, to a flight-type warewasher (1) and to a combination of this warewasher (1) and of the conveying apparatus (200, 200, 200, 200). The invention relates, moreover, to a method for loading a flight-type warewasher (1), by means of a conveying apparatus (200, 200, 200, 200) and to a preferred use of same for loading a warewasher with trays or tray-like washware (100).

A warewasher includes a scrap reducing arrangement located within a wash zone for capturing scrap debris falling downward toward a tank. The scrap reducing arrangement is configured to automatically deliver captured scrap debris away from the tank when liquid spraying within the wash zone ceases.

A warewash machine includes a housing defining a chamber for receiving wares, the chamber having at least one spray zone, a wash spray system for spraying wash liquid onto wares and a rinse spray system for spraying rinse liquid onto wares. At least one radar transceiver is located for detecting wares feeding into the chamber and/or for detecting wares within the chamber. A controller is associated with the radar transceiver and configured to identify one or more of ware location, ware movement, ware size, ware shape and/or ware material based upon outputs from the at least one radar transceiver. The controller is further configured to control at least one operating parameter of the machine based at least in part upon identified ware location, identified ware movement, identified ware size, identified ware shape and/or identified ware material.
