Under the new regulations the milk in the vat has to be cooled to 10’C or below within four hours of commencement of milking, or down to 6’C or below within six hours of commencement, and within two hours of completion of milking. The milk must also be held at 6’C or below until collection or the start of the next milking, and must not exceed 10’C during subsequent milkings. The Chillboost is essentially a timer encased in a waterproof module, it connects a shunt to the existing vat thermostat at preset intervals, the timer is set to activate the chiller system around thirty minutes before the start of milking, and “tricks” the chiller thermostat into thinking that the milk is actually warmer than it really is.
