EVAPORATED MILK STRIKING 109 



operation of the vacuum pan. If the evaporated 

 milk happens to be a trifle too heavy he can dilute 

 it with distilled water until the Beaume reading 

 is just right. See also " Standardization," Chapter 

 XXXIX, page 253. 



Correction of Beaume Reading at Temperatures 

 Other than 60 Degrees F. At a temperature of 120 

 degrees F. the Beaume reading of the finished batch 

 of standard evaporated milk may vary between 

 about 6 and 8 degrees B., according to season of 

 year and locality. At 60 degrees F. the Beaume 

 reading is approximately 1.83 degrees B. higher. 



If it is desired to record the Beaume reading 

 at the correct temperature, i. e., 60 degrees F., and 

 it is not convenient to cool the evaporated milk to 

 that temperature, the reading at any temperature 

 may be corrected as follows : when the temper- 

 ature at which the Beaume reading is taken is above 

 60 degrees F., multiply the difference between the 

 temperature of the observed reading and 60 by the 

 factor .0313 and add the product to the observed 

 reading. 



Example: Beaume at 120 degrees F. is 6.8; what 

 is the reading at 60 degrees F. ? 

 Answer: 6.8 + (60 X .0313) = 8.68 degrees B. 



The corrected Beaume reading is 8.68 degrees B. 

 When the temperature at which the reading is 

 made is below 60 degrees F., multiply the differ- 

 ence between the temperature of -the observed 

 reading and 60 by the factor .0313 and subtract 

 the product from the observed reading.
