i No cost allowances are included for boilers because many dehydration plants install second-hand 

 boilers at a fraction of cost of new ones. For example, 1 plant purchased a second-hand 125-horsepower boiler 

 at an -installed cost, including accessory equipment, of approximately $8,000. 



Estimates of costs of new boilers including piping and auxiliaries, but not foundations or buildings, are as 

 follows (from 1 to 2 boiler horsepower are required for each ton of daily capacity, unprepared basis, for blanch- 

 ing and incidental uses only): 



Developed horsepower: Price per horsepower Developed horsepower: Price per horsepower 



25 $250 200. $125 



50 200 300 100

2 Because of their drying characteristics, sweetpotatoes are not included. The drier and the floor-space 

 requirements are different because of the need for more tray area.
