larger than where the bottles pass directly from the delivery wagons 

 to the bottle washer. 



A clean bottle-storage room is of considerable advantage for 

 storing bottles after washing. This room should be located between 

 the bottle-washing room and the bottle-filling room. In this room 

 the bottles are allowed to remain after washing until cooled, when 

 they maj^ be filled. It is important that there be no congestion either 

 at the milk-receiving door or the door where the empty bottles are 

 received. Therefore, these two doors should be widely separated. 



PROCESSING ROOM. 



The milk-processing room may contain the pasteurizing equipment 

 and the bottle-filling apparatus, or the bottle filling may be done in a 

 separate room. Where a bottle-storage room is not provided there 

 must be space in the filling room for the empty washed bottles. A 

 convenient arrangement may be accomplished by having the pasteur- 

 izing equipment on a half-story or raised floor, so that the milk may 

 flow from it by gravity through the cooler to the bottle-filling appa- 

 ratus. On the floor above should be placed the milk-storage vats. 

 Gravity flow of milk is preferable to the use of milk pumps. The 

 only milk pump required with an elevated-floor arrangement is one 

 to raise the milk from the receiving tank on the ground floor to 

 the storage tank above. 



MILK-STORAGE ROOM. 



A well-insulated milk-storage room is necessary in all milk plants. 

 This room should be insulated with about 4 inches of cork, with ce- 

 ment on the inside and outside. It should be located so that the milk 

 may pass directly into it from the bottling room and. at the same 

 time, be convenient for loading the delivery wagons. The door 

 should swing outward, in order to save refrigeration space, and it is 

 well to have the room as nearly square as possible. The size of the 

 room will depend on the quantity of milk to be stored. There should 

 be enough room to store conveniently all the milk of one day's run 

 with convenient working space. 



The following are the approximate sizes of milk-storage rooms re- 

 quired for plants handling various quantities of bottled milk.
