110 SWEETENED CONDENSED MiLK—FILLING 
CuHapter VII. 
FILLING. 
The sweetened condensed milk is put on the market in 
barrels and in hermetically sealed tin cans. 
In Barrels.—Parrels, similar to glucose barrels, are generally 
used. They hold from three hundred to seven hundred pounds 
of condensed milk. New barrels should be used for this purpose. 
Barrels paraffined, or coated with sodium silicate, on the inside 
are most satisfactory, as they are more apt to be frée from mold 
spores. Old glucose barrels are dangerous to use, as they often 
contain decaying remnants of glucose, which cause the condensed 
milk to ferment. The new barrels are steamed out and drained 
thoroughly. The filling is facilitated by the use of a large gal- 
vanized iron funnel with a discharge one and one-half inches 
in diameter, or an ordinary milk pail with a nipple one and one- 
half inches in diameter in the bottom of the pail. When filled, 
a double layer of cheese cloth is placed over the bunghole, and 
the bung is driven in level with the staves. The barrel goods 
are sold to bakeries and candy factories. 
In Cans. — The 
canned goods are in- 
tended for the retail 
market. The cans 
used hold from eight 
ounces to one gallon 
of condensed milk. 
Most makes of tin 
cans for sweetened 
condensed milk have 
a small opening, 
three-eighths to three- 
fourths inch in diam- 
eter through which 
they are filled. The
