A system for cleaning heat exchange tubes includes one or more cleaning robots that are assembled with the tubes. Each cleaning robot includes a housing having an opening extending therethrough for receiving one of the heat exchange tubes, a scraper blade extending into the opening of the housing, the scraper blade having an inner scraping edge that opposes the outer surface of one of the tubes, a wheel coupled with the housing for rolling over the outer surface of the tube, and a motor for driving rotation of the wheel to move the cleaning robot over the outer surface of the tube. The system includes a system controller with one or more microprocessors and one or more software programs for monitoring and controlling operation of the cleaning robots.

Systems and methods may utilize a two-axis stand configured with a locator moveable along two orthogonally oriented axes. The locator may scan a tube opening. A controller may position the locator and the two-axis stand to a) scan across a plurality of tube openings, b) locate the plurality of tube openings based on the scan, and c) activate a cleaning tool to clean tube interiors associated with respective tube openings. Control may be automated and/or based on user interaction with a user interface.

A cooling device for reducing the temperature of cooked warm food in a liquid or paste-like state held in a container, in particular in a standard trolley, is provided. The cooling device includes a plate-like covering member which covers the opening cross-section of the container or of the standard trolley, wherein the covering member has vertically arranged cooling elements on the lower face thereof, which cooling elements, when the cooling device is attached and lowered, are immersed in the density of the food and a cooling medium circulates through the cooling elements, which cooling medium extracts the stored heat from the food. A stripping plate designed as a perforated sheet or as a perforated plate is provided on the lower face of the covering member, which stripping plate removes remaining food from the cooling elements during withdrawal of the cooling device.
