CAN WASHING 



cream with considerable water, which is undesirable, often 

 contributing to the development of costly butter defects. 



In the case of very thick and cold cream, it may be neces- 

 sary to dip the cans into a hot water bath and then invert them 

 over the forewarmer again to facilitate the removal of the rem- 

 nants of cream. This water bath is best provided in the form 

 of a rectangular tank, 24 inches long, 18 inches wide and 

 18 inches deep. This dipping of the cans 

 in water is somewhat objectionable because 

 the water adhering to the outside of the 

 cans runs into the cream in the fore- 

 warmer upon subsequent "dumping" and. 

 since the cans are often unclean on the out- 

 side, this water also is far from being free 

 from impurities and tends to pollute the 

 cream. Where the remnants of cream are 

 blown out of the cans with steam, the dipping 

 of the cans in hot water is largely unneces- 

 sary and may, under most conditions, be 

 omitted. 



Washing of Milk and Cream Cans. One 

 of the essential factors in the creamery's suc- 

 cessful efforts to improve and uphold the 

 quality of its supply of milk and cream con- 

 stitutes the returning to the farmer of cans 

 that are clean, dry and smell sweet. It is 

 inconsistent to urge the producer to observe

Courtesy J. G. Cherry scrupulous precautions of cleanliness and 

 sanitation in the production and handling of 

 his milk and cream, and then furnish him with cans that are 

 not clean and that contain foul odors. Even milk or cream that 

 is sweet and free from objectionable flavors and odors, when 

 poured, stored and shipped in unclean cans, will be of inferior 

 quality by the time it reaches the creamery or cream station. 

 And the psychological effect on the producer who, upon open- 

 ing the can, detects bad odors and lack of cleanliness, is dis- 

 advantageous to the cause of good milk or cream. A clean 

 and sweet-smelling can furnishes an incentive to the production 

 of cream; of good quality. An unclean can with objectionable
