level posit ion by menus of legs soldered to the, drain itself or by means 



of solder or metal posts in the. corners of the draining rack. This 

 perforated plate permits the drippings from the utensils to drain in 

 the sink. 



Rinsers. — It is important that after washing the utensils they be 

 rinsed in clean water before sterilization. This can best be accom- 

 plished by mechanical rinsers (figs. 21, 22, and 23). 



Rinsers of the percussion valve type, obtainable from plumbing 

 supply firms, may be used for rinsing cups (fig. 22). A nozzle 

 threaded to attach to a water pipe and operated by a pedal valve 

 located on the floor may be used for rinsing large utensils (fig. 23). 



Bottle rinsers, which 

 may be purchased 

 from bottle ma- 

 chinery firms, are also 

 used, and are much 

 less expensive than 

 the- percussion valve 

 type. By the attach- 

 ment of a perforated 

 metal plate about 1 

 foot in diameter, this 

 rinser maybe used for 

 both cups and larger 

 utensils. Each sink 

 should be equipped 

 with a rinser. 



In plants with eight 

 breakers or more, it 

 is economical to install a mechanically rotating brush for washing 

 cups. Bottle-washing machines, driven by a quarter horsepower 

 motor, may be purchased for this purpose from dairy-supply firms.

STEAM STERILIZER. 



(Fig. 24.) 



The steam sterilizer is an essential part of the equipment of a 

 sterilizing room. Bottle sterilizers suitable for the purpose may be 

 purchased from firms selling dairy supplies. It is more economical 

 of steam and time for plants with more than eight breakers to have 

 two small sterilizers rather than one large one, because one may be 

 operated while the other is being filled and less steam is used when 

 small lots of equipment are sterilized. In smaller plants one sterilizer 

 will be sufficient. In plants where one or two. girls are breaking, or 

 in houses where only leaking eggs are opened, a small sterilizer used 

 on a gas stove (fig. 25) may be substituted. This sterilizer, which
