Condensed Milk and Milk Powder 23 



wells and by the fact that the water supply tanks are overhead. 

 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 milk is raised to the platform in ten gallon 

 cans on the elevator. The sealing benches are equipped with self- 

 heating soldering coppers. In the place of the soldering benches 

 and hand coppers, an automatic sealing machine 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 elevator. The labeling and packing 

 room, equipped with the labeling and box nailing machines, pro- 

 vides 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 tin shop, 

 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 di- 

 rectly opposite the filling room with the railway track separating 

 the latter from the tin shop. The tin shop should have two outside 

 doors 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 tin shop, the latter may also be conveniently in- 

 stalled 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 in- 

 stalled. These gas generators contain inflammable material and 

 should, therefore, be located at a reasonable distance from the main 

 building.
