Patent ID: 8894476

Claim:
A system for reducing microbial levels on a hide of a bovine animal, comprising: a first station for stunning the bovine animal; a second station for exsanguinating the animal; a third station for applying at least one anti-microbial agent to a hide of the animal, said third station comprising a plurality of nozzles arranged around the hide of said animal in a configuration such that all surfaces of the hide are contacted with a spray emanating from said nozzles, said third station comprising: first means for contacting an animal that has a quantity of microorganisms on its hair with a first solution having antimicrobial properties, said first solution comprising an alkaline solution having a pH of between about 8 and about 13, said means including a plurality of nozzles that generate a pressurized spray comprising said first solution; second means for contacting said animal with a second solution, said second solution comprising at least one of water, an organic acid, and hydrogen peroxide, after said first solution has dwelled on the animal's hair for at least 180 seconds; and third means for contacting the animal with a solution comprising one or more of a surfactant and a wetting agent selected from the group consisting of soap, an alcohol, a fatty acid, and a detergent; wherein at least one of said first, second and third means for contacting comprise a plurality of spray nozzles; a means for removing at least some hair from the hide of the animal; a means for heating at least one of said first solution and said second solution to a temperature of at least about 90 degrees Fahrenheit; a means for reusing at least a portion of the first solution or said second solution, said means for reusing operatively associated with one of said first and second-means for contacting said means for reusing further comprising a means for collecting a waste stream comprising a pre-wetting substance, a depilatory substance and removed hair, and a means for processing said waste streams by a system comprising at least one of: a means for separating solid waste from liquid waste; a means for treating the solid waste to separate hair from other solids; a means for treating the liquid waste to produce a result selected from the group consisting of: removal and recycling of sulfides; removal of fine solid waste from the liquid; recovering and recycling water from the liquid waste; eliminating H2S gas from the liquid waste; disposal of residual sulfides in the liquid waste as sulfates; a means for filtering at least one of said first solution or second solution, said means including one or more of a filter, a screen, and a centrifuge; and wherein said removing means includes a mechanical device selected from the group consisting of blades, combs, and brushes.
