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.

Claims

1. A method of enabling reuse of water in processing of animals into food, the method comprising:

receiving water used in processing of animals into food, wherein the receiving comprises receiving water sprayed in a first processing area in which a first food processing task is performed;

treating the received water so as to convert the received water into a treated form capable of being reused in the processing of the animals into food; and

providing the treated water to be used in the processing of animals into food, wherein the providing comprises providing the treated water to a second processing area in which a second food processing task is performed.

2. The method of claim 1, wherein the first food processing task comprises spraying water onto at least one of live animals and animal carcasses, and wherein the receiving comprises receiving water that was sprayed.

3. The method of claim 2, wherein the spraying comprises spraying a mixture of water and ozone.

4. The method of claim 1, further comprising chilling the treated water.

5. A method of processing animals into food, comprising:

performing the method of claim 1; and

processing animals into food, wherein the processing comprises performing the first food processing task in the first processing area and the second food processing task in the second food processing area, and wherein the processing further comprises using the treated water in the second processing area.
