An apparatus and method for producing a foam surfactant suitable for a bovine teat dip comprises air pressurization of a surfactant solution containing a germicide, disinfectant, biocide, etc., passing the air-surfactant mixture through a flow or line mixer to a foam holding cup adjacent the teat area and expanding the mixture in the holding cup to produce an adherent surfactant foam product with reduced run off, which both protects and reduces infection of the teat and surrounding udder area.

[ What is claimed is:] [1.]1. A system for producing a foam teat dip, comprising:a.) a container for supplying liquid surfactant and germicide to a teat cup;b.) a flow and mixer line including: a liquid lifting pipe connected to the flow and mixer line and positioned within the container, the liquid lifting pipe defining an entry port positioned within the container for entry of surfactant and germicide, and intake ports disposed on the liquid lifting pipe within the container for intake of air;c.) the teat cup being configured to surround a bovine teat and defining an open upper end adjacent an udder portion near the teat, the teat cup defining an inlet fluid expansion bore connected to the flow and mixer line for receiving a mixture of compressed air, surfactant and germicide;d.) the flow and mixer line being sized and constructed in conjunction with the inlet fluid expansion bore for supplying surfactant and germicide from the container, and entrained air under pressure from the air intake ports to the inlet fluid expansion bore of the teat cup; and,e.) a compressor for supplying air under pressure to the container, the compressor being adapted to:i. pressurize air within the container to force air, surfactant and germicide into the liquid lifting pipe;ii. mix pressurized air, surfactant and germicide in the connecting flow and mixer line;iii. forwarding the mixture of pressurized air, surfactant and germicide from the flow and mixer line to the inlet fluid expansion bore of the teat cup; and,iv. expanding the mixture of pressurized air, surfactant and germicide down to ambient pressure in the teat cup, thereby producing a foam inside the teat cup which adheres to the teat and adjacent udder portion.
