Abstract

A grinder for grinding a material. The grinder may include a number of first rollers for grinding the material to a grind of substantially a first predetermined particle size and a number of adjustable second rollers for grinding a portion of the grind of the first predetermined particle size to a grind of substantially a second predetermined particle size.

Claims

exact text as granted — not AI-modified
1 . A grinder for grinding a material, comprising: 
 a plurality of first rollers for grinding the material to a grind of substantially a first predetermined particle size; and    a plurality of adjustable second rollers for grinding a portion of the grind of the first predetermined particle size to a grind of substantially a second predetermined particle size.    
   
   
       2 . The grinder of  claim 1 , wherein the grinder comprises a roller grinder.  
   
   
       3 . The grinder of  claim 1 , wherein the plurality of first rollers comprises a pair of crusher rollers.  
   
   
       4 . The grinder of  claim 1 , wherein the plurality of first rollers comprises a pair of finish rollers.  
   
   
       5 . The grinder of  claim 1 , wherein the first predetermined particle size comprises about 200 to about 300 microns.  
   
   
       6 . The grinder of  claim 1 , wherein the plurality of adjustable second rollers comprises a pair of fines rollers.  
   
   
       7 . The grinder of  claim 1 , wherein the plurality of adjustable second rollers comprises a length less than the plurality of first rollers.  
   
   
       8 . The grinder of  claim 1 , wherein the plurality of adjustable second rollers comprises a length of about half of the plurality of first rollers.  
   
   
       9 . The grinder of  claim 7 , wherein the plurality of adjustable second rollers comprises an engagement with the plurality of first rollers of zero to about one hundred percent.  
   
   
       10 . The grinder of  claim 1 , wherein the second predetermined particle size comprises at least about forty microns.  
   
   
       11 . The grinder of  claim 1 , wherein the plurality of adjustable second rollers comprises a fixed roller and an adjustable roller.  
   
   
       12 . The grinder of  claim 1 , further comprising a densifier.  
   
   
       13 . A coffee grinder for grinding coffee beans, comprising: 
 a plurality of crusher rollers to provide coffee grinds;    a plurality of finishing rollers to finish the coffee grinds to substantially a first predetermined particle size; and    a plurality of adjustable fines rollers for grinding a portion of the coffee grinds to substantially a second predetermined particle size.    
   
   
       14 . The grinder of  claim 13 , wherein the grinder comprises a roller grinder.  
   
   
       15 . The grinder of  claim 13 , wherein the first predetermined particle size comprises about 200 to about 300 microns.  
   
   
       16 . The grinder of  claim 13 , wherein the plurality of adjustable second rollers comprises a length less than the plurality of first rollers.  
   
   
       17 . The grinder of  claim 13 , wherein the plurality of adjustable second rollers comprises a length of about half of the plurality of first rollers.  
   
   
       18 . The grinder of  claim 16 , wherein the plurality of adjustable second rollers comprises an engagement with the plurality of first rollers of zero to about one hundred percent.  
   
   
       19 . The grinder of  claim 13 , wherein the second predetermined particle size comprises at least about forty microns.  
   
   
       20 . A method of grinding coffee beans, comprising: 
 grinding a first plurality of beans in a first plurality of rollers to a particle size of substantially about 250 microns;    grinding a second plurality of beans in a second plurality of rollers to a particle size of substantially about 40 microns; and    combining the first plurality of beans and the second plurality of beans.    
   
   
       21 . The method of  claim 20 , wherein the particle size of substantially about 250 microns comprises about 250 microns plus or minus about 20 microns.  
   
   
       22 . The method of  claim 20 , wherein the particle size of substantially about 40 microns comprises about 40 microns plus or minus about 10 microns.  
   
   
       23 . The method of  claim 20 , wherein the second plurality of beans comprises a portion on the first plurality of beans.
