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.
