It would be noticed that some coffee will be 

 twisted, and, of course, this will tell afterwards 

 in the grading. The further the weight is out 

 on the lever and the more the feed door is open , 

 the more power will be required for driving the 

 machine, and, therefore, I would advise 

 planters that, if the power at their disposal is 

 limited, instead of exercising too much pressure 

 on the coffee allow the coffee to come out 

 unpolished, and to again pass it through the 

 machine to obtain the polish required. 



In some plantations I have visited I have 

 seen them use two Smouts or one Okrassa and 

 one Smout one on top of the other the upper 

 one for shelling and the lower for polishing 

 with the screws or cones reversed, one running 

 to the right and the other to the left, in order 

 that the discharge spout of the upper machine 

 coincides with the hopper of the low T er one. 

 When these Smouts are combined with exhaust 

 fans for the purpose of separating the dust and 

 husks from the clean coffee, a sliding door will 

 be found on the vertical pipe just at the point 

 where the coffee enters this pipe. This sliding 

 door serves to regulate the amount of suction 

 draught made by the fan. The cylinder on the
