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 195° C. 
Corn (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. 
Coimcohs. — 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. 
E miner. — 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 Avhen 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 195° C. 
Oats, Feed oats, and Mixed Feed oats. — Use 100 grams of grain 
and 150 cubic centimeters of oil and extinguish the flame when the 
thermometer reaches 195° C. With oats, especially those that are 
light and chaffy, special care should be taken to insure thorough 
mixing of the oil and grain. In extreme cases it may be necessary 
to add an extra 50 cubic centimeters of oil and to heat with a slower 
flame in order to reduce foaming to a minimum. Coincident with 
the use of a 100-gram sample, the use of the special oat graduate is 
discontinued and the regular-sized graduate is used in its place. 
Rice (unhulled). — Use 100 grams of grain and 150 cubic centi- 
meters of oil, and extinguish the flame when the thermometer regis- 
ters 200° C. 
^Milled Rice (head, second head, and screenings) and Brown Rice. — 
Use 100 grams of grain and 150 cubic centimeters of oil. Place a 
glass-wool or mineral-wool pad 3 inches in diameter and y$-y± inch 
thick in the bottom of the flask. Care should be taken not to 
displace the wool pad while placing the oil and grain into the flask. 
Cut off the heating unit when the thermometer registers 200° C.
