Milking Machine

• Vacuum

• Atmosphere - 14.7 lbs/sq. in.

• Mercury rise 30 in. - barometric pressure

• Milking machine - 13 to 15 in.

TerminologyTerminology

• Pulsation ratio

• % of time milk phase

• % of time rest phase

• Desirable 50:50 to 70:30

• Pulsation rate

• no. of cycles per minute - 50 - 60

Machine Milking SystemMachine Milking System

• Vacuum supply• negative pressure to remove and move milk - 11 to 14

inches of mercury• Pump - CFM - 1.5 - 2.0 times calculated need• Length and diameter of lines 1 - 3”• No. of units and accessories• Reserve tank- vacuum resevoir resevoir• Pulsator - rate and ratio• Vacuum regulator• Problems - worn - too small pump, leaks, worn
