ABSTRACT:
In a disclosed modular freeze branding method, refrigerant is caused to flow through a first thermally conductive conduit having exposed, coplanar segments that are arranged in the shape of a set of characters. Then the exposed portions are applied to brand a specimen of livestock, after which the flow of refrigerant is stopped. The above acts are then repeated one or more times with different sets of thermally conductive conduit. The conduit of the different sets have exposed segments that form different sets of characters. An operator can employ the method to efficiently apply individual, multiple-digit freeze brands to each of a number of specimens of livestock. Variations and apparatus are also disclosed.
