EQUIPMENT FOR STERILIZING 51 
for sterilizing, either in pressure sterilizers in 
which the cans, pails, and other small apparatus 
can be confined, or steam can be used through 
jets injected into cans, pails, etc. Only large 
dairies can afford to pay the cost of steam boilers. 
Cheapest Steam Sterilizer 
The United States Department of Agriculture 
has designed a sterilizer 
consisting of a small 
kerosene stove upon 
which stands an_ or- 
dinary roasting pan 
full of water, on top 
of which is placed a 
galvanized iron lid with 
a short jet which ex- 
tends upward from 
the center. The water 
boiled in the roasting 
pan quickly creates 
steam, which ascends 
through the jet, and heats the can or pail placed 
upon it.
