Abstract: An apparatus for cleaning a carcass includes an elongate housing having a forward and a rearward frame disposed in parallel, transversely opposed relation to one another. The elongate housing includes a plurality of stations. At least one rotating device at each station is disposed on the forward or rearward frame. A first station may include a pair of transversely opposed counter-rotating devices disposed at a common downward angle relative to a longitudinal axis of the elongate housing. A second station includes a plurality of rotating devices positioned near the top of the apparatus to clean the hoof and ankle area. A third station includes a plurality of vertically stacked rotating devices. A fourth, fifth, and sixth station include plural rotating devices in axial alignment with one another that are collectively oriented in a predetermined downward slope relative to the longitudinal axis to clean a carcass from top to bottom.

Abstract: An apparatus for washing a split animal carcass includes upper and lower pairs of upwardly inclined brushes, leading and trailing vertical brushes, and upper and lower pairs of downwardly inclined brushes. The upwardly inclined brushes are transversely spaced apart from one another to accommodate an animal carcass between them, as are the downwardly inclined brushes. First and second fluid headers are positioned in parallel relation to each inclined brush and three fluid headers are associated with the vertical brushes. The first inclined fluid headers have nozzles aimed at the carcass and the second inclined fluid headers have nozzles aimed at the brushes. Two of the vertical brush fluid headers are aimed at the vertical brushes and the third fluid header is aimed at the carcass.

Abstract: A washer cabinet has a bottom floor, a top wall, and a pair of upstanding sidewalls to define a channel that extends the length of the cabinet. The channel has an entry end and an exit end. An overhead track suspends animal carcasses in alignment with the channel. A plurality of rotating appendages and a plurality of fluid nozzles are positioned within the cabinet. An animal carcass suspended from the overhead track is moved into the cabinet through the entry end. The carcass comes into contact with the rotating appendages and is washed by fluid emitted from the fluid nozzles as it traverses the length of the cabinet before exiting at the exit end.

Abstract: An apparatus for washing the neck area of an animal carcass includes a pair of upwardly inclined brushes sharing a common angle of inclination, followed by a first pair of vertically disposed brushes, a second pair of vertically disposed brushes, and by a pair of downwardly inclined brushes sharing a common angle of inclination. The brushes of each pair of brushes are transversely spaced apart from one another to accommodate an animal carcass between them. First and second fluid headers are positioned in parallel relation to each inclined brush. A neck area of a carcass is initially cleaned by the pair of upwardly inclined brushes and associated fluid headers. The neck area then passes between the first and second pair of vertical brushes and associated fluid headers. The final cleaning is administered by the pair of downwardly inclined brushes and their associated fluid headers.

Abstract: Methods of contacting a surface of an object with a liquid are provided. Aspects of the invention include positioning an object in a reaction chamber and flowing a liquid across a surface of the object, where at least a portion of the flowing step occurs in the presence of a gas that limits evaporation of a solvent component of the liquid. Also provided are devices for practicing the subject methods.
