THE CITY MILK PLANT 



97 



The cans, when empty, may be turned up on a drip- 

 saver, which, as the name indicates, saves whatever milk 

 may drip out from the cans. Just beyond the drip-saver 

 is the can washer. The cans are taken from the drip-saver, 

 washed, steamed, and taken out by another door to the 

 dray, which hauls them back to the railway station to be 

 returned to the shipper. 



Sanitary Piping. Having passed the inspector, the milk 

 is emptied into a receiving vat, from which it is pumped 

 into a storage tank that feeds 

 the pasteurizer. This necessi- 

 tates passing the milk through 

 considerable piping as well as 

 a pump. Needless to say, the 

 pumps should be of the sani- 

 tary type, so that they may be 

 taken apart and thoroughly 

 cleaned after each using. The 

 piping must be the so-called 

 sanitary piping, being tinned 

 throughout, having a perfectly 

 smooth interior, and in short 

 lengths joined by couplings eas- 

 ily taken apart with a spanner 

 wrench. These pipes should be 

 washed daily by rinsing with 

 cold water, then pumping hot 

 washing powder solution through them and finally rinsing 

 with plenty of boiling hot water. 



However, they should be taken apart and thoroughly 

 cleaned with a brush and sterilized at least once each week. 



Clarifying. The presence of dirt or sediment of any 

 kind in milk is strenuously objected to by the consumer.
