The sorting arrangement is associated with at least one loading arrangement (13a, 13b, 13c) for automatically loading the different conveying tracks of the at least one conveyor dishwasher (1, 1′) with washware (9a, 9b, 9c) of one of the previously defined or definable washware groups.

A warewash machine for washing wares includes a chamber for receiving wares, the chamber having an inlet side, an outlet side, multiple spray zones between the inlet side and the outlet side, and a conveyor arrangement for moving wares along a conveyance path through the multiple spray zones in a ware travel direction. A prescrapping zone is located toward the inlet side of the chamber, the prescrapping zone having a blow-off system comprising a plurality of prescrapping nozzles and a compressed air feed line for delivering compressed air to the prescrapping nozzles.

A warewash machine carries out at least one of (i) delivering both compressed air and rinse liquid to a plurality of wash spray nozzles of the warewash machine for spraying onto the wares during at least part of a washing operation of a ware cleaning cycle, wherein the wash liquid is recirculated from a wash tank below the spray zone; or (ii) lowering wares from the spray zone into a wash tank below the spray zone to submerge the wares within wash liquid of the wash tank and delivering compressed air into the wash tank during at least part of a washing operation of a ware cleaning cycle; or (iii) delivering both compressed air and rinse liquid to a plurality of rinse spray nozzles of the warewash machine for spraying onto the wares during at least part of a rinsing operation of a ware cleaning cycle.

Disclosed is a cleaning device for cleaning items to be cleaned. The cleaning device has at least one cleaning chamber and at least one covering device at least partially surrounding the cleaning chamber. The covering device can be moved in an opening movement direction from a closed position into an open position or in a closing movement direction from an open position into a closed position by means of at least one electromechanical drive via at least one transmission. The cleaning device furthermore has a sensor, which is designed to detect an action of a manual force on the covering device in the opening movement direction or in the closing movement direction. The cleaning device is furthermore designed to control the electromechanical drive in accordance with the detection of the action of the manual force.

A system (10) for loading at least one conveyor warewasher (1, 1′) with washware includes a feed conveyor belt (11) for delivering washware to at least one loading region of the conveyor warewasher (1, 1′) and a detection system (15), in particular an optical one, configured to detect at least one of the following parameters of the washware on the feed conveyor belt (11) when delivering the washware (9a, 9b, 9c) to the loading region: (i) a type of the washware, (ii) a degree of soiling of the washware, and/or (iii) an order of the washware and/or an alignment of the washware relative to the feed conveyor belt (11). The detection system (15) has an assigned evaluation device, which is configured to control the delivery of the washware to the at least one loading region as a function of at least one of the detected parameters.

A conveyor type ware washing machine uses a heat pump to reduce exhaust heat and to heat incoming water. A modulating valve is used to control incoming water flow through a heat exchanger of the heat pump. Processing circuitry automatically dynamically adjusts the modulating valve between a plurality of open states based on the sensed refrigerant head pressure of the heat pump, so that the refrigerant head pressure is maintained in a predefined range. The ware washing machine is efficient, and reduces the amount of heat exhausted to ambient. Related methods are also disclosed.

A conveyor dishwashing machine (1) has at least one washing zone (7), and at least one final rinse zone (8) which is connected downstream (as viewed in the transport direction (T) of the wash items) of the at least one washing zone (7). The conveyor dishwashing machine (1) has a transport apparatus for transporting the wash items through the treatment zones (6, 7) of the conveyor dishwashing machine (1) so that the wash items are situated at least in regions in a washing plane (5) which runs horizontally. The washing plane (5) is configured as a main washing plane, and there is at least one additional washing plane (6) in at least one of the treatment zones (7, 8) of the conveyor dishwashing machine (1), in which additional washing plane (6) wash items can be treated.

A device for recovering energy from hot wares includes a standalone cabinet structure having a housing that defines an internal rack receiving space and an energy recovery system associated with the cabinet structure. The rack receiving space is sized to receive and hold multiple racks of hot wares at the same time. The energy recovery system is configured to transfer heat from the hot wares to a fluid passing through the cabinet structure. A method of recovering heat from wares, and a warewash machine that includes an energy recovery system are also described.

A method for cleaning items to be cleaned is disclosed. A cleaning device is used that has at least one cleaning chamber and at least one applicator for applying at least one cleaning fluid to the items to be cleaned in the cleaning chamber. A desired hygiene value is prespecified. The method further includes time-resolved recording of at least two influencing variables which influence hygienization of the items to be cleaned. Hygiene share values are determined from the influencing variables using a prespecified relationship between each influencing variable and the respective hygiene value share of said influencing variable. An expected actual hygiene value at the end of the cleaning from the hygiene value shares is ascertained and compared with the desired hygiene value. At least one of the influencing variables is changed based on the comparison. An inventive cleaning device is also disclosed.
