  • Patent number: 11134696
    Abstract: Apparatuses and methods for applying an antimicrobial agent to food products include methods and systems for limiting the escape of antimicrobial agent to the environment during antimicrobial treatment of the food product. In one embodiment, a series of cabinet panels moves in line with the passing food product and forms an enclosure around the food product by means of panels closing ahead of and behind the food product. In another embodiment, the direction and spray pattern of positively charged aerosolized antimicrobial particles is controlled by attracting the particles to preselected negatively charged regions within a treatment volume.
    Type: Grant

  • Patent number: 10206407
    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.

  • Patent number: 9961920
    Abstract: Systems and methods for processing cattle ears into pet treats by high-pressure processing are provided. The cattle ears are covered with a liquid, such as water, and exposed to high hydrostatic pressures for about one minute. The high hydrostatic pressures remove hair and implants from the cattle ears while preserving the texture and consistency of the ears, which are appealing to dogs and other pets.

  • Patent number: 8715759
    Abstract: An antimicrobial intervention for the production of ground meats by treating the exterior of the meat trimmings with an antimicrobial agent before grinding. An apparatus for applying an antibacterial agent to meat trimmings includes a closed or essentially closed chamber for limiting the escape of the antimicrobial agent to the environment during antimicrobial treatment of the trimmings, an entrance system for introducing trimmings into the closed chamber while preventing or significantly limiting the antimicrobial agent from escaping into the environment, an application system for applying an effective amount of the antimicrobial agent to exposed surfaces of the trimmings in the closed chamber; and an exit system for removing the treated trimmings from the closed container while preventing or significantly limiting the escape of antimicrobial agent into the environment.

  • Patent number: 7828636
    Abstract: Methods, devices, and systems are provided for washing an animal intestine. The device may include one or more flushing arms connected to a rotating fluid tank. The rotating fluid tank provides the fluid to the flushing arms, which in turn provide the fluid to the animal intestine. The rotating fluid tank may be adapted to rotate about a substantially vertical axis and during such rotation moves the flushing arms through a number of working sections around the washing machine.
