The invention is directed to an improved pan cleaning machine that has a cleaning section that comprises a plurality of frames for mounting a sequence of interchangeable modular cleaning mechanisms. It can include quick-release mounting arrangements so that cleaning mechanisms can be quickly changed for cleaning different types of pans or to replace brushes or other wearing parts of cleaning mechanisms when they require replacement. In some embodiments, the frames for mounting the cleaning mechanisms can comprise swing arms so that the cleaning mechanisms can be swung away from the cleaning position so that the cleaning mechanism can be removed and replaced without interrupting the operation of the machine. If the machine is stopped, the swing arm can still be used to facilitate access to the cleaning mechanism to reduce the time needed to complete the maintenance or replacement. This also allows the position of the cleaning mechanism in relation to the baking pans to be adjustable during the cleaning process which can permit increased application of brushing forces or prevent overloading and also permits easy jam removal. In addition, the swing arm makes the pan cleaning machine more adaptable for cleaning pans with different depths and customizable. A method of operation and control, including pre-programmed cleaning cycles and various control paradigms is also provided.

A loading system for loading a conveyor warewasher, wherein a piece of washware placed in a first region of a conveyor belt can be moved to or in the direction of a second region of the conveyor belt. The conveyor belt includes a clock-in lane subdivided into an upper first section and a lower second section and, in a region between the sections, a turning apparatus is arranged and configured to turn a piece of washware picked up from the clock-in lane and moved in the region between the first and second sections by 180 and subsequently transfer the piece of washware to the second section of the clock-in lane. Below the region between the first and second sections of the clock-in lane, a dirt collection region is provided, in which dirt can be received, having fallen from the piece of washware by way of gravity.

A dishwasher includes a heat recovery apparatus to recover at least a portion of the thermal energy of discharged exhaust air as utility heat and transfer it to a treatment liquid to be sprayed in the dishwasher. The heat recovery apparatus includes a primary circulation system having a heating pump assembly and a first secondary circulation system with a first heat exchanger unit configured such that at least a portion of the recovered energy is transferred to a carrier medium circulating in the first secondary circulation system. The first secondary circulation system includes a second heat exchanger unit configured such that at least a portion of the energy transferred to the carrier medium is transferred as utility heat for warming the treatment fluid to a refrigerant of the heating pump assembly of the primary circulation system, the drying air circulating in the primary circulation system.

A warewasher conveyor assembly that may be a loader version or an unloader version for a commercial dishwasher. The warewasher conveyor assembly has a base and a chain conveyor assembly movably mounted to the base. The chain conveyor assembly is movable between a generally level in-use position and a tilted cleaning position where one end is raised, which allows for more convenient cleaning. The warewasher conveyor assembly also includes a movable support, such as a gas spring, which holds the chain conveyor assembly in the cleaning configuration. Related methods are also disclosed.

The invention relates to a handling module for loading a transport device of a conveyor dishwasher. The handling module comprises a turning wheel for turning a dishware item, a supply ramp and a feed ramp for transferring the dishware item from the turning wheel to a transport device of the conveyor dishwasher, wherein the feed ramp has at least one waste disposal opening, wherein the turning wheel is designed to receive the dishware item supplied via the supply ramp in an orientation with a use side facing upwards, wherein the turning wheel is also designed to turn the dishware item and to place same on the feed ramp with the use side facing downwards, wherein, when placing the dishware item on the use side, waste on the dishware item can be disposed of via the waste disposal opening due to gravity. The invention also relates to a cleaning system comprising the handling module, as well as a method for cleaning items to be cleaned.

A commercial baking dry pan cleaning system is provided having a support frame with one or more modular swing arms mounted thereto. One or more controllers is provided to control the one or more modular swing arms. One or more unclean pan conveyors provides a stream of unclean baking pans to the system. The controller engages one or more actuators to operate the one or more modular swing arms which swing around one or more pivot points to swing a cleaning subsystem or module into contact with the unclean stream of pans. A position limiter is coupled to each of the swing arms to set an initial operating position. The limiter communicates with the controllers. The cleaning subsystem is swung into position on the modular swing arm to engage the unclean pan. The controllers are adapted to sense and control a pressure exerted by the cleaning subsystems on the pan and maintain pressure within a pressure range. The controller whilst sensing the pressure exerted on the pan can also sense certain error conditions thereby disengage the pan if the sense pressures are outside of ranges.

A dish cleaning system for washing and automatically storing dishes includes a cabinet which defines an interior volume therein. The interior volume includes a loading space, a washing space, a drying space, and a storage space. A dish rack is positionable in the cabinet and is configured to hold a plurality of dishes. He drives system is mounted in the cabinet and is configured to move the dish rack between the loading space, the washing space, the drying space and the storage space. A washing assembly is provided which is configured to wash contents of the washing space of the interior volume of the cabinet.

A dishwasher rack is able to rotate with respect to the dishwasher to permit access to all areas of the dishwasher rack from one side of the dishwasher. A spin arm is coupled to the dishwasher rack. The spin arm rotates with respect to a guideway that is coupled to a mounting frame. The mounting frame has wheels so that it can travel within the wheel tracks of the dishwasher.

A conveyor device includes: a first rotating body; a second rotating body; an endless belt entrained between the first rotating body and the second rotating body; and a plurality of engaging portions provided on a surface of the endless belt and engageable with the first plates. The conveyor device further includes: a first portion including the first rotating body and located mainly in water of the water tank; and a second portion including the second rotating body and located mainly above the water of the water tank. In the first portion, the endless belt is configured to move upward at a first angle with respect to a water surface of the water tank. In the second portion, the endless belt is configured to move upward at a second angle larger than the first angle with respect to the water surface of the water tank.
