Each mill is equipped with one or more bulk receiving systems 

 rated at 2,000 bushel-per-hour. Hopper cars are unloaded at two differ- 

 ent rates depending on the weight per cubic foot of the ingredients and 

 flowability. The rate for corn and pellets is 60 tons per hour and for the 

 soft or lighter ingredients 42 tons per hour. Boxcars are unloaded with a 

 power shovel, also at two different rates: corn and pellets at 42 tons per 

 hour and soft goods at 15 tons per hour. Bagged ingredients are unload- 

 ed from l)Oxcars or trucks at a rate of six tons per man-hour. 



The receiving crew sets the gates and controls but does not unload 

 l)ulk ingredients, dry or liquid, when delivered by truck. The truck 

 driver performs the unloading. 



In addition to their unloading function, the receiving labor must 

 position and open cars and clean them out after they are emptied. The 

 crew must also clean up around the receiving sink. In the three larger 

 mills which are equipped with automatic control devices for mixing, the 

 receiving crew must move and dump bagged ingredients into small over- 

 head working bins. 



The labor requirements for receiving, reduced to a man-equivalent 

 basis, vary from 0.2 in Mill A to 2.1 in Mill F. and are given in Talile 3.
