First Time Operation
As explained above, cluster removal occurs after a threshold delay time. This time may be
converted to represent removal flow rate. Below is a simple formula to calculate the
required value of
F2
per desired flow rate for removal.
*At the end of milking, about 200grams (0.20 Kg = 0.44lb [6.5 oz.]) of milk is released each time
the milk valve is opened for dumping milk to the milk line.

Smooth Removal
Shutting the vacuum off when the pulsation is still active releases the liner vacuum
pressure off the teat. is a short delay time between the vacuum shut-off and cluster
removal (pulsation stops with removal piston retraction) allowing the liner to smoothly
slide off the teat before it is pulled up by the removal piston.

Quick Cluster Removal
Quick removal is an option for early removal of the cluster for cows with low yield. This
feature prevents over-milking of cows at the beginning of lactation, when their production
is low.
Quick removal is activated if during the pre-milk time (afimilk delay parameter F1), the
cow gave the entire yield expected from it. In such situations, the cluster removal after
pre-milk time will be at a faster flow rate (removal process is initiated at half of the regular
removal delay [F2]).
The quick removal option is activated via a user-configured parameter F4 that may be set
to either enabled or disabled. In addition, AfiFarm allows the user to assign a code to
enable quick removal for specific cows (example: all cows within 10 days from calving).
