EQUIPMENT AND oe ae SIRUP ON A SMALL 
SCALE 
By M. A. McCauip and C. F. Watton, Jr., Bureau of Chemistry, U. S. Depart-

MILL AND EVAPORATOR 
The small size of individual acreages of cane and the fact that the 
tonnage produced in a given locality is not always so centrally placed 
as to permit efficient operation of a large custom plant, frequently 
render it necessary for farmers to make sirup on a comparatively 
small scale. The capacity of mill, engine, and evaporator should 
be so chosen as to permit economical and steady operation. The 
sirup-making season usually lasts only five or six weeks, during 
which period a horse-driven mill, with a kettle or small evaporator, 
can handle a season’s output ranging from 1,500 to 2,500 gallons of 
sirup. A power mill, with a larger evaporator steadily operated, is 
adequate for a 10,000-gallon output. Table 5 may be of assistance 
in selecting mills, engines, and evaporators of appropriate capacity.
