Condensed Milk and Milk Powder

have been devised which are more or less efficient in "cutting off" 

 the milk without "slobbering." The filling machines now in use 



vary from the primitive hand filler, in 

 which the condensed milk is "ground 

 out" by the turning of a crank by hand, 

 to the most perfect forms of automatic 

 filling machines. In these filling ma- 

 chines, all parts coming in contact with 

 the condensed milk are constructed of 

 brass. They are equipped with a reser- 

 voir, receiving tank, or hopper, which has 

 an automatic feed, usually a floating de- 

 vice attached to a valve, which regulates 

 the inflow according to the discharge. 

 The discharge is adjustable to fill any 

 size can with a , remarkable degree of

thousand cans per day (ten hours). 

 These machines are of complex construction and must receive 

 proper care. It is best to clean them thoroughly after each day's 

 work. But, since their 

 inlet and discharge 

 are closed hermetic- 

 ally, the complete 

 washing may be done 

 once per week only, 

 without seriously dis- 

 turbing their efficien- 

 cy or impairing the 

 product. For thor- 

 ough cleaning, the 

 filler should be dis- 

 sected, removing all 

 detachable parts, such 

 as valves, pistons, 



tubes etc. When
