 the old style the machine had to be dismounted. 



Now, with regard to the Okrassa Combined 

 Peeler and Polisher, in this machine there are 

 two weights to regulate one corresponding to 

 the peeling compartment and the other to the 

 polishing compartment, the weights being 

 screwed up and down, instead of sliding along 

 as in the Smout machine. This is, of course, 

 much handier. The regulation of the weights 

 is similarly effected as in the Smout machine, 

 but the following should be observed. When 

 regulating the weight appertaining to the 

 peeling compartment it should be done so that 

 the coffee is simply delivered husked, allowing 

 as much of the pellicle as possible to remain on 

 the coffee. The coffee should not be allowed to 

 proceed to the polishing compartment until this 

 adjustment has been made. In this machine 

 there is a neat and ingenious automatic arrange- 

 ment for the regulation of the suction from the 

 fan. The suction must be regulated so that 

 when the coffee is delivered from the peeling 

 compartment into the polishing compartment 

 all the dust and husks generated in the peeling 

 operation should be drawn away by the action 

 of the fan. The polishing operation is a 

 repetition of the peeling in reality it amounts
