DeLaval milk meter MM25
These four milk meters measure the milk
flow to obtain the milk weight from each
quarter. They also measure conductivity
level of the milk.
Control box
Control box contains electronics and pilot
valves that control the milking and cleaning
processes, vacuum, and distributed IO.
Receiver
Milk is collected in the receiver before it is
transported to its final destination, usually
the storage tank.
Milk pump
The milk pump pumps the milk to the
storage tank after each cow has been
milked. The milk pump can also be
equipped with milk sample outtake for milk
sample and DeLaval online cell counter
OCC (both optional equipment).
Purge valve
Membran valves
Valves
The purge valve admits compressed-air into
the milk line before a system cleaning is
started. The compressed-air pushes the
remaining milk in the line to the tank. The
valve is also used to clear the lines of water
after a system cleaning. There is an
indication hole in the bottom side of the
valve housing. If milk is leaking out from the
hole, it indicates a damaged o-ring in the
purge valve.
The two membrane valves direct the milk
either through the delivery line (to storage
tank) or the divert line (to drain or milk pail).
On each membran valve housing bottom
side, there is an indication hole. Leaking
milk from this hole indicates damage to the
valve membrane.
