BEET ROOT SUGAR. 20S 



Many are of opinion, that boilers of the middle 

 size are best suited to the purpose; for instance, 

 such as will hold from eighty to ninety gallons. It 

 is believed that two of these would perform the same 

 as one holding 5 or 600 gallons ; for while the pro- 

 cess of defacation is being carried on in one, the oth- 

 er is undergoing the process of precipitation. 



All boilers, intended for the process of defacation, 

 should be in height equal to its diameter. Room 

 should be allowed in the boiler for the operation of 

 boiling, as for instance, if the boiler is to contain 

 200 gallons of juice, it should be made large enough 

 to hold 240 gallons. The boiler should be stationed 

 at such a height, that the syrup may be easily run off 

 into the boilers for evaporation. The temperature 

 ought never to rise above 2 1 2 degrees Fahrenheit. If 

 the boiler is 36 inches both in height and in diameter, 

 the grate should be 23 inches in length, and 1 5 inches in 

 breadth, and should be made of cast iron, having ten 

 bars. The necessary apparatus belonging to a defa- 

 cating boiler, are as follows : 



1st. An areometer and a thermometer. 



2d. A bin and buckets for lime. 



3d. A pair of scales with weights for weighing 

 lime. 



4th. A copper or lead measure for sulphuric acid. 



5th. A spoon plated to examine the juice, and a 

 saucer for experiment. 



6th. A wooden spatula to stir the syrup in the boiler.
