CLEAN MILK 



The cooling arrangement is precisely as described above for 

 cooling milk to be shipped in cans. When there are eight or ten 

 milkers, so that the milk from as many cows may be mixed as soon. 

 as milked without loss of valuable time when it should be cooling, 

 then the warm, mixed milk may properly be drawn directly into the 

 bottles from the bottle filler. The bottles should, on being filled, be 

 instantly immersed to the neck in ice water. In this way bottled 

 milk may be suitably cooled, with the avoidance of the unnecessary- 

 exposure to two tanks and the air in passing over the cooler. The 

 bottle filler is indispensable (see Fig. 28) for conveniently filling 

 several bottles at once. By moving a lever one can fill from four to

eighteen bottles to the same level at one time. The prices of these 

 contrivances vary greatly with the size and material used in their 

 construction. 



The sterilizer is an important utensil. It is a tight chamber 

 into which steam is turned, with the object of destroying germs, and 

 is made to hold the bottles and absolutely every other dairy utensil 

 with which milk comes in contact. 



The germs are not only those which may have inhabited the 

 milk, but occasionally there may be germs of disease contaminating 

 the returned bottle, owing to it having been in a house in which 

 such disease existed.
