THE BROWN-DUVEL MOISTURE TESTER, 19 
Barley, — Use 100 grams of grain and 150 cubic centimeters of oil, 
and extinguish the flame when the thermometer registers 190° C. 
Barley malt. — Use 100 grams of malted barley and 200 cubic 
centimeters of oil, and extinguish the flame promptly when the ther- 
mometer registers a temperature of 168° C. The flame should be 
adjusted so that it will require approximately 20 minutes to reach 
the prescribed temperature. 
Buckwheat. — Use 100 grams of grain and 150 cubic centimeters of 
oil and extinguish the flame when the thermometer registers 185° C. 
Com {maize). — Use 100 grams of grain and 150 cubic centimeters 
of oil, and extinguish the flame when the thermometer registers 
190° C. This method, however, can not be used with pop corn. 
Corn meal. — Use the double-wall flask with 100 grams of the corn 
meal and 150 cubic centimeters of oil in the inner flask and 150 
cubic centimeters of oil between the walls. Extinguish the flame when 
the temperature reaches 175° C. The oil in the inner flask should 
reach 175° C. in 26 minutes. 
Corncobs. — Use 50 grams of cob cut in pieces that can be easily 
removed from the flask and 250 cubic centimeters of oil, and extin- 
guish the flame when the thermometer registers 190° C. 
Cottonseed. — Use 50 grams of seed and 150 cubic centimeters of 
oil and extinguish the flame when the thermometer registers 190° C. 
Distillers' dried grains. — Use 50 grams of distillers' dried grains 
and 200 cubic centimeters of oil, and extinguish the flame promptly 
when the thermometer registers a temperature of 190° C. Special 
care should be taken to see that the oil and the distillers' dried grains 
are thoroughly mixed before beginning the test. 
Emmer.—Use 100 grams of grain and 150 cubic centimeters of oil 
and extinguish the flame when the thermometer registers 190° C. 
Flaxseed. — Use 100 grams of seed and 150 cubic centimeters of oil, 
and extinguish the flame when the thermometer registers 175° C. 
Grain sorghums. — Use 100 grams of grain and 150 cubic centi- 
meters of oil, and extinguish the flame when the thermometer regis- 
ters 190° C. 
Navy beans. — Use 100 grams of grain and 150 cubic centimeters of 
oil and extinguish the flame when the thermometer reaches 175° C. 
Oats. — Use 50 grams of grain and 150 cubic centimeters of oil, and 
extinguish the flame when the thermometer registers 195° C. In 
oats that are light and chaffy, special care should be taken to insure 
the thorough mixing of the oil and grain and to heat with a slower 
flame in order to reduce the foaming to a minimum. In extreme cases 
it may be necessary to add an extra 50 cubic centimeters of oil. Use 
special graduate which is one-half the volume of the regular gradu- 
ate; or, if the regular graduate is used, double the moisture test 
reading. 
Rice (unhulled). — Use 100 grams of grain and 150 cubic centi- 
meters of oil, and extinguish the flame when the thermometer regis- 
ters 190° C. 
BrovM rice. — Use 100 grams of grain and 150 cubic centimeters of 
oil. Place a glass-wool pad, 2 inches in diameter and % inch thick, 
in the bottom of the flask, taking care not to disturb it when putting 
in the grain and oil. Extinguish the flame when the thermometer 
registers 190° C.
