A free-standing Energy Recovery System enables sanitary recovery of thermal energy with heat transfer from hot waste effluent to incoming domestic water. The source of the effluent may, for example, be conventional commercial ware-washing, clothes washing equipment, pasteurization and other industrial processes.

A system for optical wash item recognition for commercial dishwashers embodied as conveyor dishwashers or as automatic programme dishwashers, in particular hood dishwashers, wherein the system includes an optical recognition system, especially a camera, for recording at least one two-dimensional image of at least some of the wash items to be treated in the dishwasher. The system also includes an analysis device for analysing at least one recorded image in such a way that individual wash items or groups of individual wash items in the recorded image are located and classified. At least one neural network is used to analyse the at least one recorded image.

A method of washing induction cookware having a cookware content, using induction heating and a water jet, and comprising a washing process having the steps of: heating the cookware during a washing cycle; washing the cookware in the washing cycle with a cold-water jet; drying the cookware after the washing cycle; heat sanitization of the cookware; and steam sanitization of the cookware, whereby the washing process is analyzed by a vision system, the washing process is controlled and adjusted by a controller having parameters varying between each of the cookware content; whereby the parameters are derived from an interfaced cooking apparatus and from a manual input and whereby the vision system serves to regulate a water pressure, a water flow, a heating temperature, and time durations between each of the cookware content, with each of the cookware content having a cooking base, a food contact surface, recipe ingredients cooked, a cooking temperature, and a cooking duration.

A system and method for cleaning a reusable dish, comprising: picking a dirty dish from a load module disposed to contain at least one dirty dish with a robotic arm, wherein said dirty dish is stained with material that needs to be removed prior to reuse; transporting said dirty dish from said load module to a wash module with said robotic arm; cleaning said dirty dish in said wash module having the means to transform said dirty dish into a clean dish, wherein said clean dish does not exhibit any material that needs to be removed prior to reuse; transporting said clean dish from said wash module to a store module with said robotic arm; and dropping off said clean dish in said store module, wherein said store module is disposed to contain at least one clean dish, whereby each dirty dish is cleaned thoroughly and efficiently with individual attention in real time.

Systems and/or methods for the monitoring and/or control of thermal sanitization in automated cleaning machines are described. A cleaning machine controller may predict a number of heat unit equivalents that will be delivered during a cleaning process based on a sump temperature difference (i.e., a change in the temperature of the cleaning solution in the sump) experienced at or near the beginning of the cleaning process. One or more cleaning process parameters may be adjusted and/or controlled based on the sump temperature difference in order to ensure that a target number of heat unit equivalents are delivered in order to achieve thermal sanitization of the wares subjected to the cleaning process.

A dishwasher (1) comprises a washing chamber (2) configured for receiving crockery (3) to be washed, which can be accessed via a first lateral zone (5a) and a distinct second lateral zone (5b). The dishwasher (1) comprises a lid (6) configured for being rotated, with respect to the washing chamber (2), around a rotation axis (7) passing through the washing chamber (2), between a first position, in which it prevents accessing the said washing chamber (2) both via the first lateral zone (5a) and via the second lateral zone (5b), and a second position in which it allows accessing the washing chamber (2) via at least one between the first lateral zone (5a) and the second lateral zone (5b).

A dishwasher (1) includes a treatment zone (3) and a conveyor apparatus (4) for transporting washware items (2) from a placement area (5) through the treatment zone (3) to a removal area (6). A washing and/or rinsing system has at least one washing and/or rinsing pump (9) and washing and/or rinsing nozzles. The dishwasher (1) is spatially partitioned into an over table area (7), which, when the dishwasher (1) is used as intended, is positioned above a counter level (13), and an under table area (8), which, when the dishwasher (1) is used as intended, is positioned below the counter level (13), wherein the placement area (5), the removal area (6) and the treatment zone (3) are respectively part of the over table area (7), and wherein at least the washing and/or rinsing pump (9) of the washing and/or rinsing system is part of the under table area (8).

A system for ascertaining fresh water consumption by an, in particular, commercial dishwasher (1) or a component thereof. The system includes a container (12, 22) for temporarily storing liquids, wherein the container (12, 22) has a liquid inlet (25), which can be flow-connected to a fresh water source if required, and a liquid outlet (23), which can be flow-connected to a freshwater consuming means, in particular a freshwater consuming means of the dishwasher (1), if required. The system further includes at least one pressure sensor (B3, B4) for detecting an, in particular, hydrostatic pressure in the container (12, 22), and an evaluation device which is designed to ascertain a fresh water volume flow into the container (12, 22) depending on at least one output value of the at least one pressure sensor (B3, B4).

A box-type dishwasher (1), wherein the dishwasher (1) has a fresh-water connection (20) with a feed valve (21), wherein a water-treatment system with a reverse-osmosis device (22) is provided downstream of the feed valve (21) in order to treat, in particular as required, as least some of the fresh water fed to the dishwasher (1) via the fresh-water connection (20), wherein a backflow preventer (6) is provided between the feed valve (21) and the reverse-osmosis device (22) in order to prevent water from flowing back from the dishwasher (1) into a fresh-water-supply installation (100) which is, or can be, flow-connected to the fresh-water connection (20).

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.
