Claim 6:
7. A handheld teat preparation apparatus configured to selectively dispense a pre-dip solution to a teat prior to milking, and selectively dispense a post-dip solution to said teat after milking, said handheld teat preparation apparatus, comprising:
a. a handpiece including a teat receiving body with a top opening, a bottom opening and cylindrical sidewalls that form a center bore configured to receive a teat, said teat receiving body includes a high-pressure air port configured to receive high-pressure air, a pre-dip port configured to receive a pre-dip solution and a post dip port configured to receive a post-dip solution;
b. an upper circular raceway and a lower circular raceway formed in said teat receiving body, both said upper circular raceway and said lower circular raceway extending around said center bore, said upper circular raceway communicates with said high-pressure air port to receive high pressure air and said lower circular raceway communicates with said pre-dip port and said post-dip port to received said pre-dip solution and said post-dip solution, said upper circular raceway and said lower circular raceways being isolated from each other so that said high pressure air delivered to said upper circular raceway does not flow into said lower circular raceway and said pre-dip solution or said post dip solution delivered to said lower circular raceway does not flow into said upper circular raceway;
c. a first set of nozzles formed on said sidewalls of said teat receiving body that communicates with said upper circular raceway to deliver said high-pressure air to said center bore;
d. a second set of nozzles formed on said sidewalls of said teat receiving body, said second set of nozzles being located below said first set of nozzles and communicates with said lower circular raceway to deliver said pre-dip solution or said post-dip solution to said center bore; and,
e. a high-pressure air source that delivers high-pressure air to said high-pressure air port;
f. a pre-dip solution source that delivers said pre-dip solution to said pre-dip port;
g. and a post-dip solution source that delivers said post-dip solution to said post-dip port;
h. a control unit connected to said high-pressure air source, to said pre-dip solution source, and to said post-dip solution source, said control unit configured to control the flow of said high-pressure air from said high-pressure air source to said handpiece, control the flow of said pre-dip solution from said pre-dip solution source to said handpiece, and control the flow of said post-dip solution from said post-dip source to said handpiece.
