Summary

TESTS, CARRIED OUT DURING SUMMER ROAD JOURNEYS AND IN A TUNNEL AT 303 K (30 DEG C) AMBIENT, HAVE MADE IT POSSIBLE TO MEASURE TEMPERATURE VARIATIONS IN A MILK LOAD. THE TESTS LASTED 43 HOURS USING A TANKER WHOSE HEAT TRANSFER COEFFICIENT EXCEEDED THE PRESCRIBED VALUE (0.7 W/M3.K) BY 17%. WHEN THE LOAD IS SHAKEN, THE TEMPERATURE VARIATIONS DO NOT EXCEED 0.5 K, BUT WHEN THE TANKER IS STATIONARY FOR 33 HOURS, SOME POINTS LOCATED NEAR THE NON-INSULATED MANHOLES GRADUALLY RISE TO 281 K (8 DEG C). THE AVERAGE MILK TEMPERATURE RISES BY 2.2 K OVER 41 HOURS. ONE DEGREE KELVIN IS LOST WHEN INTRODUCING COLD MILK INTO THE TANKER PREVIOUSLY CLEANED WITH HOT WATER.
