Milking shell
stainless steel
For milking, the liner is placed inside a metal or plas-
tic container. Then the vacuum enters this chamber
through the air hose and the milking process takes
place. Shell must have a certain weight so that the
milking process can be done well. On the other hand,
shell steel should be completely resistant to acid
corrosion and not made of steel. It means that it will
not be attracted to the magnet and will not change
color over time. Any change in the appearance of the
shell after contact with acid indicates the poor qual-
ity of the shell material and its short life. One of the
characteristics of low-quality milking shells is rust-
ing and then causing tears in the milking liner.
