arrows. If a hillside location is not available the same routing dia- 
gram will apply, but the materials will have to be lifted to the work- 
ing platform. The space required, not including that for storage 
of materials or finished product except that under the platform, is 
approximately 23 by 26 feet. 
A steam double-cooker plant is shown in Figures 33 to 36, inclusive. 
Dimension data for plants of 600 and 800 gallons capacity are given 
in Tables 2 and 4. Sizes and lengths of pipes for transmitting heat 
are based on steam pressure at 5 pounds per square inch and provide 
sufficient surface to heat the water from 60° to 180° F. in 40 minutes 
and to bring the mixture to the boiling point in 15 minutes. It is

assumed that water under pressure sufficient to force it into the 
boiler is available. When this is not the case a feed pump or injector 
must be used. The size and capacity of pump required depend upon 
the conditions.° 
Figure 37 shows an arrangement of the community or large orchard 
double-cooker steam plant illustrated in Figures 33 to 36 inclusive, and 
located on a level site. The routing differs from that shown in Figures 
31 and 32 in that the finished product is handled from the opposite 
end of the cooking tank, the movement of the materials through the 
plant being as indicated by lines and arrows. The space required, 
not including that for storage, is approximately 24 by 26 feet.

particular installations.
