also to water and steam piping. Large quantities of piping and 

 fittings are expensive, cause extra labor, and in the case of milk 

 pipes may be insanitary. The course of the milk through the plant 

 should be as direct as possible from the receiving tank, through the 

 clarifier, pasteurizer, and bottling machines to the cold-storage room. 

 Mechanical conveyers should be used whenever labor and time can 

 be saved; otherwise the extra expense incident to their use is not 

 warranted.

At 73 plants the number of milk pumps used varied from none to 

 4, and the milk piping used from none to 300 feet. A wide range 

 occurred in plants in the same class, as well as in plants of the same 

 size. For example, at 26 plants of class 4 the length of milk piping 

 varied from 20 to 210 feet, and the number of milk pumps varied 

 from 2 to 4, and at 20 plants handling from 2,001 to 5,000 gallons 

 daily the length of the milk piping varied from 30 to 300 feet and the 

 number of milk pumps from none to 4. 



Great lengths of milk piping cause extra labor and expense and 

 tend to increase the loss of milk both from milk sticking to the sides
