A SYSTEM FOR DRY SEPARATION OF KERNEL FROM SHELL

摘要

A SYSTEM FOR SEPARATION MIXTURE OF KERNEL AND SHELL (CRACKED MIXTURE) COMPRISES A FIRST VERTICALLY POSITIONED COLUMN (110) DEFINED BY A FIRST TOP OPENING (119), AND A SIDEWALL (118) HAVING A FIRST INLET CHUTE (111) FOR RECEIVING CRACKED MIXTURE TO BE SEPARATED AS WELL AS A FIRST OUTLET CHUTE (112) WHEREIN THE FIRST INLET CHUTE (111) IS POSITIONED AT A LEVEL HIGHER THAN THE FIRST OUTLET CHUTE (112); A FIRST AIR BLOWING MEANS (113) ASSOCIATED TO BOTTOM PORTION OF THE FIRST COLUMN (110) TO INTRODUCE A FIRST AIR FLOW INTO THE FIRST COLUMN (110); A FIRST CYCLONE MEMBER (115) HAVING A FIRST INLET (116) CONNECTED THE FIRST TOP OPENING (119) VIA A FIRST CONDUIT (114) AND A FIRST OUTLET (117); A SECOND VERTICALLY POSITIONED COLUMN (120) DEFINED BY A SECOND TOP OPENING (129), AND SIDEWALLS (128) HAVING A SECOND INLET CHUTE (121) CONNECTED TO THE FIRST OUTLET (117) AS WELL AS A SECOND OUTLET CHUTE (122) WHEREIN THE SECOND INLET CHUTE (121) IS POSITIONED AT A HIGHER LEVEL THAN THE SECOND OUTLET CHUTE (122); A SECOND AIR BLOWING MEANS (123) ASSOCIATED TO BOTTOM PORTION OF THE SECOND COLUMN (120) TO INTRODUCE A SECOND AIR FLOW INTO THE SECOND COLUMN (120); AND A SECOND CYCLONE MEMBER (125) CONNECTED TO THE SECOND TOP OPENING (129) THROUGH A SECOND CONDUIT (124) WHEREBY THE FIRST AIR FLOW IN THE FIRST COLUMN (110) GENERATES AN UPWARD FORCE TO DELIVER A FIRST LIGHT-WEIGHTED FRACTION OF THE CRACKED MIXTURE INTO THE SECOND COLUMN (120) THROUGH THE FIRST CYCLONE MEMBER (115) AND THE SECOND AIR FLOW, WHICH IS RELATIVELY LOWER THAN THE FIRST AIR FLOW, GENERATES ANOTHER UPWARD FORCE IN THE SECOND COLUMN (120) TO DELIVER A SECOND LIGHT-WEIGHT FRACTION FROM THE FIRST LIGHT-WEIGHTED FRACTION OF THE CRACKED MIXTURE INTO THE SECOND CYCLONE MEMBER, WHILE THE CRACK MIXTURE, WHICH IS NOT DELIVERED BY THE FIRST AND SECOND AIR FLOW, FALL ONTO THE FIRST (112) AND SECOND OUTLET (122) CHUTES TO BE DISCHARGED.
