36 BuiivDiNG AND EQUIPMENT 



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 aug- 

 mented by their close proximity to the vacuum pans and the hot- 

 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, or is forced by a piston pump into the tanks 

 feeding the filling machines. The sealing benches are equipped 

 with "self-heating soldering coppers. In the place of the soldering 

 benches and hand coppers, automatic sealing machines may be in- 

 stalled. 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, 

 provides for considerable storage of the finished product. Addi- 

 tional 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 di- 

 rectly 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 ar- 

 ranged 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
