Patent number: 5964656Abstract: In the inventive method for the sanitary rinsing of an animal, an assembly line is provided which includes a plurality of shackles. Each shackle includes an inventive RFID tag which includes a machine readable unique shackle number. Once an animal is stunned and attached to a shackle the animal is moved to a weighing station, which is equipped with an RFID tag reader, weighs the animal and transmits the weight and shackle number to a computer where the data is recorded in a database. The animal is then bled and moved to a rinsing station, which is equipped with an RFID tag reader which reads the shackle number. The system then looks up the weight of the animal to be rinsed at that particular rinsing station and calculates the amount of solution to inject into the circulatory system of the animal.Type: GrantFiled: May 19, 1998Date of Patent: October 12, 1999Assignee: Meat Processing Service Corp.
