Milk cooling a hot issue

Snap chilling of milk will become regulation over the next few years. This creates a number of problems.
Reading Time: 2 minutes

With power consumption a big issue, pre-chilling plate coolers maxed out and hot water demand for plant cleaning even more important, add the necessity for milk in the vat not to be above 10C on subsequent milkings, then achieving these targets are going to be challenging.

After two and half years of development Dale Stone and Matt Parkinson of SnapChill have come up with a solution.

By using ice to snap chill the milk into the vat at 5-7C, recharging the ice between milkings using off-demand power, using the ice generation to create 80C hot water which is supplied back to the hot water cylinder, Stone and Parkinson have solved these issues which increases security of supply for farmers and supply companies.

“Using technology and making it more efficient, the challenge was to give something back. 80C water supplied back to the cylinder while the machine is making ice was it.

“People look confused when we say we are using ice to make hot water,” Parkinson says.

“Milk cold into the vat, recharging during off-peak power times, plenty of hot water so you can hot wash after every milking. It is an excellent solution.”

As the machine also uses water for cooling there are no messy antifreeze products required. This eliminates the possibility of antifreeze getting into the milk should a plate crack in the cooler. SnapChill has been designed around serviceability as well, as parts are off the shelf.

“As farmers increase productivity they must look at the other end of the production line, farm refrigeration.

“It’s no use increasing production to watch it all go down the drain because your chiller cannot cope.

“The whole farm pivots around your refrigeration system. By the addition of SnapChill the existing refrigeration becomes a holding chiller.

“SnapChill has many advantages; it is a win win for the farmer and the dairy industry,” he said.
