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 70 is adopted to allow for possible fractional capacities. 



EQUIPMENT FOR PRYING. 



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 :
