Abstract: Methods and systems enable reuse of water in processing of animals into food. In one method, water used in processing of animals into food is received. The water is treated so as to convert the water into a treated from capable of being reused in the processing of the animals into food. The treating includes reducing the amount of solid particles in the water and adding gas to the water. The treated water is provided to be used in the food processing.

Abstract: Various food processing methods and a food processing system minimize microbial growth while an animal, such as a chicken, is processed into food. During processing, temperature of an animal carcass and atmosphere surrounding the carcass are controlled by spraying gases and a mixture of ozone and water on the carcass, directing the gases through a passage in a wall to cool a processing area, and flowing the gases into atmosphere surrounding the carcass. Preferably, the gases include ozone and cryogenic gases recycled from a cryogenic freezer. The system uses a reduced amount of fresh water by recycling water used during food processing.

Abstract: The present invention relates to a filter unit, and a filtering system using the filter unit. The filter unit includes a housing having a longitudinal axis and an inlet and outlet for fluid containing solid contaminants and a back-flush inlet and back-flush outlet for cleansing fluid. This housing contains a substantially cylindrical filter element which has a longitudinal axis coincident with the longitudinal axis of the housing. The filter element has disposed within it a conduit, adapted to be opened to atmospheric discharge, having a longitudinal axis coincident with the longitudinal axis of the filter element. The conduit also has disposed along its surface cleansing members, which extend from the conduit to the filter element and have apertures to allow the cleansing fluid to flow through the members and into the conduit.
