  • Publication number: 20080038422
    Abstract: An apparatus (10) for washing eviscerated poultry carcasses (12) has a housing (11), a conveyor (15a) for moving the shackled poultry carcasses through the housing. A guide bar (24) tilts the poultry carcasses (12) from a vertical position for spraying by a first set of nozzles (23). The first set of nozzles (23) delivers a cleaning solution (100) at a sufficient flow rate and line pressure, whereby a portion of the cleaning solution (100) is deflected back out the rear opening (12d) of the poultry carcass (12).

  • Publication number: 20070163966
    Abstract: A food processing effluent refurbishing system of the present invention refurbishes effluent water in a first and a second food processing loop. The system includes first and second circulation systems, first and second balance tanks, and a side stream. The first circulation system circulates water through the first food processing loop. The first balance tank connected to the first circulation system refurbishes effluent water circulating through the first food processing loop. The second circulation system circulates water through the second food processing loop. The second balance tank connected to the second circulation system refurbishes effluent water circulating through the second food processing loop. The side stream connects the first and second circulation systems.

  • Publication number: 20070084802
    Abstract: A system of the present invention provides on-site reclamation, reconditioning, and re-use of poultry processing water. The system is connectable to a washing apparatus and comprises a first receptacle, a filter, a dispenser, a channel, a second receptacle, piping, and a plurality of pumps for circulating the processing water through the system. The processing water leaving the washing apparatus is collected in the first receptacle and pumped to the filter, where the processing water is filtered. As the processing water is being filtered, the dispenser dispenses an antimicrobial solution and water onto the filter. The debris filtered from the processing water is removed through the channel. The filtered processing water is then collected in the second receptacle prior to re-use.

  • Patent number: 6147120
    Abstract: A synergistic composition and a synergistic system for use in treating the skin and hair of people and animals comprises separate treatment compositions (solution, dispersions, emulsions, suspensions or other liquid or liquefiable materials). One treatment with a first composition that may comprise at least 0.1% by weight of antimicrobially active aliphatic phenol derivative and treatment with another composition being selected from the group consisting of:a) a solution comprising an antimicrobially active cationic species;b) a comprising antimicrobially active aliphatic phenol derivative, preferably in a different weight percentage of antimicrobially active aliphatic phenol derivative than said one composition, comprising greater than 0.3% antimicrobially active aliphatic phenol derivative;c) a solution comprising an alcohol provides a synergistic antimicrobial action.
