Fig. 13. — Arrangement of equipment in proposed sweet-potato sirup plant. 
APPARATUS. 
Some of the apparatus used in the proposed plant is of the same 
size and design as that used in the experimental plant. These are 
the potato washer, mash tank, hydraulic press, evaporators, filter 
press, and flavoring kettle (pp. 7—12). Two larger cooling tanks are 
substituted for the smaller cooling tank, and an additional evap- 
orator is provided for handling the filtered sirup. The following 
additional apparatus is necessary in the construction of a plant of 
the capacity of the one proposed:

Endless Belt Conveyer. 
The endless belt conveyer for carrying the sweet potatoes from the 
storehouse to the potato washer is a standard type. The belt is 24 
inches wide and is approximately 55 feet long. The shape of the 
supporting idlers gives the belt a concave surface. Power is secured 
from an electric motor and countershaft. The driving pulley makes 
15 revolutions per minute, giving the belt conveyer a speed of 23 
feet a minute, using a 6-inch conveyer pulley.
