SIMPLE APPLIANCES FOR MIXING. 293 



requisite water and yeast ferment, 100 molasses, 100 to 110 pul- 

 verized oil cake. It was concluded that the percentage of wheat 

 flour was not sufficient. Fourth experiment: 30 wheat flour 

 with water and the requisite ferment, combined with 100 molas- 

 ses, etc. In the other series of experiments, the preparations 

 were heated in a furnace up to the temperature of 95 to 100. 

 Corn flour was found preferable to wheat flour the combination 

 used being 100 corn flour, 100 molasses and the remainder bran. 

 After a thorough mixing, the ration was cooked in a furnace for 

 from 9 to 10 hours. It was further considered, in a series of 

 practical experiments, what forage was the most suitable to be, 

 combined with the molasses, and w~hat was the most desirable 

 duration of the period of heating or cooking in the furnace. 



In Germany, special molasses mixing appliances are sold for Simple appli- 

 $60, their capacity being nearly 500 Ibs. per hour. This appar- ance 

 atus is about 6 feet long, 12 inches wide and 16 inches deep. 

 The mixing shaft has a velocity corresponding to 35 revolutions 

 per minute. An apparatus for mixing 3 tons of the fodder per 

 hour may be had for $150. In this case the revolving shaft 

 turns with a velocity of about 150 revolutions per minute. When 

 the molasses combination is finished, it is emptied on a 

 cemented floor and allowed to cool. Certain precautionary 

 measures are to be taken during the mixing, for there is dan- 

 ger of fire; but this danger may be obviated by having a thick- 

 ness of only 18 inches of the product during the. mixing in the 

 special apparatus. After 24 hours' cooling the molasses com- 

 bination may be put up in bags and after several days addi- 

 tional cooling, it may be stored in warehouses just as sugar is. 



Molasses ma} 7 be rendered liquid by heating at 70 to 75 R. 

 The concentrate is added, and then thoroughly mixed until 

 cooling. Experience shows that the mixing tanks should be 

 made of wood, rather than iron, and be rather shallow. The 

 cost of this operation is very slight, as one man can prepare 

 fully two and a half tons of this forage per diem. A mixing 

 appliance of the Werner and Pfleiderer system, containing 400 

 liters, may produce 5 tons per diem. For concentrates, one 

 may use to advantage bran, dried malt, dried brewers' waste, 

 etc. The best proportion for this mixing is one part of each.
