38 BUILDING AND EQurpMENT 
soldering benches and hand coppers, automatic sealing machines 
may be installed. The sterilizers and shakers are conveniently 
placed to take care of the sealed evaporated milk. The tin cans 
for the sealing room and the box shooks for the packing room 
are brought down from the storage room overhead on the ele- 
vator. The labeling and packing room, equipped with the label- 
ing and box nailing machines, provides for considerable storage 
of the finished product. Additional storage at a moderate and 
uniform temperature might be provided for by a basement under 
the packing room. <A label stock room furnishes satisfactory 
storage for the labels. 
In case the factory manufactures its own tin cans, a tinshop, 
equipped with the necessary machinery (see list of machinery 
and equipment) should be located in as close and convenient 
proximity to the filling and sealing room as possible. A suitable 
place is directly opposite the filling room with the railway track 
separating the latter from the tinshop. The tinshop should have 
two outside doors, opening out on the track, and its machinery 
should be so arranged that the tin plate can be unloaded from 
the car at one door, is moved back through the machinery and 
appears again in the form of finished cans at the other door, 
directly opposite the filling room and ready for the reception 
of the condensed milk. Instead of erecting a separate building 
for the tinshop, the latter may also be conveniently installed in 
the second story directly over the filling room. 
Where natural gas and gas from municipal corporations is 
not available. one or more gasoline gas generators should be 
installed. ‘These gas generators contain inflammable material 
and should, therefore, be located at a reasonable distance from 
the main building. 
The tendency in factory construction today is to do away 
with al] partitions between operating rooms, having all manu- 
facturing and packing rooms in one large space. In this case 
it is customary and economical to place the vacuum pan and 
condensed milk storage tanks on an elevated platform and in- 
stalling the hotwells, coolers, vacuum pump, milk pumps, 
homogenizer, filling and sealing machines, sterilizers, labeling 
and packing machines on the main floor, which also provides
