The farmer washes the udder and attaches a milking machine to all four teats on the cow's udder. A hose runs from the milking machine to a stainless steel pipeline located overhead. The pipeline runs the length of the barn and is connected to a big bulk tank in the milk house. The milk is quickly cooled in the bulk tank.

After every milking, all contact services are washed and rinsed. Just before the next milking, the surfaces are sanitized.

The cooled milk then goes in refrigerated tanker trucks to Alta Dena Dairy for processing.
