Abstract
The present invention relates to preparing dairy animal teats for being milked, and more particularly to teat preparation, rinsing, and milking that all take place in a milking machine teat cup liner. Such a method includes: applying a teat sanitizer to the teat; injecting air into the liner to force the teat sanitizer toward a waste milk line connected to the liner; pulsating the liner at a first pulsation rate; drawing a rinsing milk from the teat; directing the teat sanitizer, the air, and the rinsing fluid to the waste milk line; pulsating the liner at a second pulsation rate to draw additional milk from the teat; and directing the additional milk to a good milk line.
Claims21
A dairy system safety valve comprising:
- a first single-seat valve having:
- a body defining, a first opening defining a first valve seat, and a second opening;
- and
- a first plunger head for movement between an open position that is spaced apart from the first valve seat, and a closed position that is engaged with the first valve seat;
- a second single-seat valve having:
- a body defining, a first opening in communication with a vent and defining a second valve seat, and a second opening in fluid communication with the second opening of the first single-seat valve, and a third opening;
- and
- a second plunger head for movement between an open position that is spaced apart from the second valve seat to open the vent, and a closed position that is engaged with the second valve seat to block the vent;
- and
- a third single-seat valve having:
- a body defining, a first opening defining a third valve seat, and a second opening in fluid communication with the third opening of the second single-seat valve;
- and
- a third plunger head for movement between an open position that is spaced apart from the third valve seat, and a closed position that is engaged with the third valve seat.
A dairy system safety valve comprising:
- a plurality of single-seat valves in fluid communication with each other, and each single-seat valve includes:
- a body defining a first opening, a second opening and a third opening, and the first opening defines a valve seat;
- and
- a plunger head for movement between a closed position engaged with the valve seat, and an open position spaced apart from the valve seat.
