Fig. 35. Chart for estimating cooling times and temperatures. Each diagonal line represents seven-eighths cooling in the time at which it crosses the seven-eighths cool line. Example: Produce cools in a test to of initial produce-to-coolant temperature difference in 30 hours, seven-eighths cooling time is 25 hours, so would cool to one-fourth of initial temperature difference in 16 hours. z < _i o o £*• i UJ LU 0C a u. 2° 0- uj o « COOLING TIME (MINUTES OR HOURS, USE ANY CONVENIENT SCALE 3 6 9 12 15 I 12 3 4 5 21 24 27 30 33 36 39 42 45 48 51 7 8 9 10 II 12 13 14 15 16 17 54 57 18 19.
