Freezing milk bulk tank

Hi, Milk Fans

If your bulk tank is freezing it’s set too cold and you stand a chance of developing rancidity in the milk.  This is because the formed ice crystals puncture the fat globules, releasing lipase.  Be sure to not switch the tank on too early – some people like to do this to give the tank a “running start”, before the milk is pumped in.

When the milk freezes, it also concentrates the milk solids, making the milk sweet and increasing the viscosity.

Kind regards,
