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
pulsator ,regulator
