Summary

MILK IS COOLED AT LEAST BELOW 278 K (5 DEG C) WITHIN 2 HRS AFTER MILKING. TWO TYPES OF COOLER ARE DESCRIBED: THE DIRECT EXPANSION TANK (WITH AN ELECTRICITY CONSUMPTION OF 16 WH PER LITRE OF MILK) THAT CAN OPERATE BY NIGHT DURING 75% OF TIME AND THE TANK WITH INTERMEDIARY LIQUID, COOLING MORE RAPIDLY BUT OPERATING MAINLY BY DAY. THE PRECOOLING OF MILK PRIOR TO STORAGE IN A TANK BY TAP OR ICED WATER AT 274K (1 DEG C) IS DESCRIBED. THE PLATE HEAT EXCHANGER IS THE MOST WIDELY USED ; THE SHELL AND TUBE HEAT EXCHANGER, CUMBERSOME, HAS THE SAME EFFICIENCY. PRECOOLING BY TAP WATER REDUCES BY ABOUT ONE THIRD THE ELECTRIC CONSUMPTION REQUIRED FOR STORAGE AT 277 K (4 DEG C). G.G.
