plan or with pumps, according to the topography of the site 
and the elevation of the rooms. ‘he receiving room floor and 
the platform which accommodates the yacuum pans, should be 
seven to eight feet above the main floor. In order to take care 
of storage of water, sugar, tin cans, barrels and box shooks, 
there should be a second floor over the well room and the filling, 
sealing and sterilizing room. The ceiling of these rooms should 
be not less than sixteen feet above the floor. 
The rooms are so arranged as to necessitate the minimum 
expenditure of machinery, conveyors and labor. All work rooms 
open on the railway switch, and the storage room is accessible 
by two elevators. The well room, where most of the steam is 
needed, is next to the boiler room, so as to minimize condensa- 
tion in the steam pipes. If the main steam pipes are properly 
insulated, this arrangement should furnish the vacuum pans with 
dry steam. The floor in the boiler room should be two feet 
below the main floor, in order to give additional fall for the con- 
densation water from jacket and coils of the vacuum pans to the 
boiler feed tank. 
The partition between the receiving room and testing room 
is equipped with a cabinet, opening on both sides so that the 
sample bottles can be placed on the shelves in the receiving 
room and taken off the shelves in the test room. 
From the weigh cans on the receiving platform the milk runs 
direct into the hot wells, which are sufficient in number to con- 
veniently divide the milk into batches and to heat the milk with 
the least possible delay. The capacity of the vacuum pumps is 
augmented by their close proximity to the vacuum pans and the 
hot wells and by the fact that the water supply tanks are over- 
head. The space to be evacuated is confined very largely to the 
vacuum pan only, the milk has to be lifted by the vacuum pump 
but a few feet and the water runs into the condenser by gravity 
From the well room the condensed milk is transferred to the 
tanks on the platform over the filling machines. ‘The evaporated 
milk is pumped from the cooling coils through the wall and the 
sweetened condensed mulk is raised to the platform in ten-gallon 
cans on the elevator, or is forced by a pressure pump into the 
tanks feeding the filling machines. ‘The sealing benches are 
equipped with self-heating soldering coppers. In the place of the
