If the seed is to be dried at each of the pulping plants, a small 
tray drier (previously described) would be the most economical to 
install for the purpose. If a 4,000-ton plant, pulping 5,000 baskets 
of tomatoes a day, requires one drying unit (all the plants under 
1,000 tons being eliminated from consideration), there would be 31 
in this class (for fractions of a unit must be considered as a whole 
unit). The eight plants of the succeeding two classes would require 
16 more units, while the plants in the last two classes would require 
proportionately more units, or about 20. On this basis the total 
number of drying units required for the several plants would actually 
be 67, but TO is adopted to allow for possible fractional capacities. 
EQUIPMENT FOR DRYING. 
The cost of the necessary equipment, including the cyclone heating 
and drying units, together with the operating cost for drying the 
seed at the pulping plants, is approximately as follows : 
Estimated 
Equipment : cost, 
Seed-separating cyclone $200 
Pump 50 
Piping 50 
Drier 100 
Fan 50 
Heater 100 
Housing 50 
Steam piping 100 
Total cost of equipment for one drying unit 700 
Total cost of equipment for drying at 70 pulping 
stations ^ $49,000 
The cost of operation has been calculated as follows :
