available, an outlet pipe is generally extended uj) through a 

 table or rack so that it projects vertically through the surface 

 about five or six inches. Cans or other utensils to be sterilized 

 are placed upside down over this steam jet and the steam turned 

 on. Forty-five seconds are required for sterilizing with live 

 steam and the can is then removed, using gloves or cloth pads 

 to protect the 

 hands, and placed 

 bottom side up to 

 drain. As the cans 

 are very hot, they 

 dry quickly. 



Where a boiler 

 is not available, a 

 homemade steam 

 sterilizer can be 

 made from a roast- 

 ingpan to which 

 has been fitted a 

 tight-fitting cover. 

 The cover can be 

 made by any tin- 

 smith and has a 

 small vertical pipe 

 soldered to it at 

 the center, which 

 acts as a chimney 

 for the escaping 

 steam. In the pan 

 is placed about one 

 inch of hot water 

 and the pan set on 

 a hot stove. When 

 the steam, which is 

 tested with a ther- 

 mometer, has reached two hundred and five degrees F., a can 

 or other utensil may be placed over the steam jet and steril- 

 ized. It requires about five minutes for sterilizing where the 

 steam is at two hundred and five degrees F. or over. A metal 

 box should be constructed to fit over the sterilizing pan. This 

 will provide a means for sterilizing strainer cloths, covers for 

 milk cans and other small articles. When dry, place covers 

 on cans, and set utensils Avhere dust will not get on them.

 sisting of a roasting pan with a special cover which 

 can be made by any tinsmith.
