Abstract
An apparatus and method for applying an antimicrobial agent to whole or split animal carcasses include a closed or essentially closed chamber for limiting the escape of antimicrobial agent to the environment during antimicrobial treatment of the carcass. In one embodiment, a series of carcass cabinet panels moves in line with the passing animal carcass and forms an enclosure around the carcass by means of panels closing ahead of and behind the carcass. In another embodiment, the direction and spray pattern of positively charged aerosolized antimicrobial particles in a carcass cabinet is controlled by attracting the particles to preselected negatively charged regions within the carcass cabinet.
Claims8
A method for continuous antimicrobial treatment of animal carcasses, comprising:
- a) providing a plurality of carcass cabinet walls defining an interior volume;
- b) aerosolizing a liquid antimicrobial agent to form aerosolized antimicrobial particles;
- c) imparting a positive charge to the aerosolized antimicrobial particles;
- d) spraying the aerosolized antimicrobial particles into the interior volume;
- e) driving at least one animal carcass through the interior volume such that at least a first portion of the aerosolized antimicrobial particles adheres to a surface of the at least one animal carcass to form a substantially uniform layer of the antimicrobial agent;
- f) imparting a negative charge to at least one evacuation region within the interior volume to attract at least a second portion of the aerosolized antimicrobial particles into the at least one evacuation region;
- and
- g) evacuating substantially all of the aerosolized antimicrobial particles within the evacuation region from the interior volume.
