I said a very low pressure would do, yet if perfect sterilization is 

 to be obtained, there should be a pressure of not less than twenty 

 Ibs., though eight or ten Ibs. of steam is practically enough and so 

 muck simpler to use than boiling water. 



If only cans are to be steamed the usual creamery mode of ap- 

 plying may do, provided time is taken to allow the steam to act. 

 This consists of having a steam pipe some three or four inches 

 through a table and having placed the inverted can over it, opening 

 the valve.

It is far better to have a box or room on the plan shown in Fig. 

 68, taken from Wis. bulletin. There is a square box made of galvan- 

 ized iron with a door and a vent for the escape of steam v. The 

 steam enters at ST. P through a pipe provided with a dropcock c, and 

 with four openings ST. PV with pipes P inserted, and one sv opening 

 into the upper part of the box. There are two shelves ws of wire 

 netting, and the lower space is used for cans placed directly over the 

 B team pipes P, while the upper shelf is used for bottles, covers, etc. 

 This and similar boxes are made by Cornish, Curtis & Greene Mfg. 

 Co.. Ft. Atkinson, Wis. and may be made in any size or styles to suit.
