THE PASTEURIZATION OF MILK 



Bottle-Filling 



The filling of the bottles is more an economic 

 problem than a sanitary one. Of course, the care- 

 ful cleaning and sterilization of the apparatus is 

 necessary, no matter what kind of filler is used. 

 Any failure in this respect may cause the milk to 

 gather up bacteria while it passes through the 

 bottling machine. This may cause annoyance, at 

 least, when tests are made which indicate a high 

 bacterial content. If, however, the cleaning is 

 carefully done, the items which most interest the 

 milk men are the questions of expense and of effi- 

 ciency in operation. 



If a machine is operated by hand power, there 

 is the question whether human power is cheaper 

 than machine power. If automatically operated 

 by outside power, either electric, steam or hydrau- 

 lic, then the matter of bottle breakage, case dam- 

 age, and loss of milk from broken bottles is an 

 important consideration. A power-driven machine 

 may or may not be slower in operation than hand 

 power. The conditions surrounding each plant 

 must be considered and decisions made in accord- 

 ance with them.
