Abstract

The disclosed embodiments herein include methods and apparatus for processing vegetables having a root crown including applying opposing forces to the vegetables to separate the roots or portions thereof at or near the root crown from the vegetable, and packaging the vegetables in a container.

1. A method of processing green onions having bulbs including root crowns comprising: securing providing a clamping member; providing a pair of liked sized reversely rotating members spaced a first distance from the clamping member; clamping a top portion of each of the green onions with the bottom of their root crowns spaced the first distance from the clamping member; moving the secured clamped green onions in a generally vertical disposition with their root crowns disposed adjacent to the rotating members to cause extending roots to move into engagement with a pair of like sized reversely the nip of the rotating members spaced a short distance from the root crowns; driving the rotating members sufficiently to apply an abrupt jarring force to a bottom portion of each of the green onions acting substantially in the direction opposite the top portion and in line between the top and bottom portions of each one of the green onions to rip apart a root crown to separate a bottom portion only of the root crown from the remaining portion of each green onion or removing a substantial portion of the roots upon engaging the rotating members; and packaging the green onions in a container. 
     
     
       2. A method according to  claim 1 , wherein said applying force includes applying force to the bottom portion of each one of the green onions below the intersection of the root crown and the bulb in the opposite direction to the top portion of the green onion to rip apart the root crown from the bottom portion of the green onion. 
     
     
       3. A method according to  claim 1 , further including discarding the separated portions of the green onions. 
     
     
       4. A method according to  claim 1 , further including discarding the separated portions of the green onions. 
     
     
       5. A method according to  claim 1 , further including singulating a group of the green onions prior to the applying of force. 
     
     
       6. A method according to  claim 5 , further including washing the singulated green onions. 
     
     
       7. A method according to  claim 6 , further including peeling the foreskins from the singulated green onions. 
     
     
       8. A method according to  claim 7 , further including supporting the singulated green onion vertically by its stalk. 
     
     
       9. A method according to  claim 8 , further including translating the green onions along a path of travel. 
     
     
       10. A method according to  claim 1 , further including translating the green onions substantially vertically along a path of travel into engagement with a de-rooter to apply force to the bottom portion of the green onion. 
     
     
       11. A method according to  claim 10 , further including translating the green onions to a second de-rooter to repeat the applying of force to the bottom portion of the green onions. 
     
     
       12. A method according to  claim 10 , wherein the applying of force is caused by holding the top portion of the green onion while the de-rooter applies force to the bottom portion of the green onion. 
     
     
       13. A method according to  claim 12 , further including washing the green onions after separating the bottom portion therefrom. 
     
     
       14. A method according to  claim 13 , further including grouping the green onions. 
     
     
       15. A method according to  claim 10 , wherein the rotating members include a pair of pinch rollers. 
     
     
       16. A method according to  claim 10 , wherein the rotating members include a pair of meshing gears. 
     
     
       17. A method according to  claim 1 , further including subsequently repeating the applying the abrupt jarring force acting substantially in the direction opposite the top portion and in line between the top and bottom portions of each one of the green onions to help ensure the ripping apart of the root crowns from the remaining portion of each green onion. 
     
     
       18. A method according to  claim 1 , wherein the driving the rotating members sufficiently to apply the abrupt jarring force includes holding the green onions individually by the top portions thereof moving them seriatim to a de-rooting station, and applying the abrupt jarring force to the bottom portion of each green onion in the direction opposite to the top portion of each green onion upon engaging the rotating members. 
     
     
       19. A method of processing green onions having bulbs including root crowns comprising: providing a clamping member for clamping the green onions; providing a pair of liked sized reversely rotating members spaced a first distance from the clamping member; clamping a top portion of each of the green onions with the bottom of their root crowns spaced the first distance from the clamping member; moving the secured clamped green onions in a generally vertical disposition with their root crowns disposed adjacent to the rotating members to cause extending roots to move into engagement with a pair of like sized reversely the nip of the rotating members spaced a short distance from the root crowns; driving the rotating members sufficiently to apply an abrupt jarring force to a bottom portion of each of the green onions acting substantially in the direction opposite the top portion and in line between the top and bottom portions of each one of the green onions to rip apart a rot crown to separate a bottom portion only of the root crown from the remaining portion of each green onion or removing a substantial portion of the roots upon engaging the rotating members. 
     
     
       20. A method of processing green onions having bulbs including root crowns comprising: securing providing a clamping member; providing a movable clamp spaced a first distance from the clamping member; clamping a top portion of each of the green onions with the bottom of their root crowns spaced the first distance from the clamping member; moving the secured clamped green onions in a generally vertical disposition; engaging the secured green onions with their root crowns disposed adjacent to the movable clamp to cause extending roots to move into engagement with a vertically the movable clamp spaced a short distance from the root crowns; driving the clamp sufficiently to apply an abrupt jarring force using the vertically movable clamp to a bottom portion of each of the green onions acting substantially in the direction opposite the top portion and in line between the top and bottom portions of each one of the green onions to rip apart a root crown to separate a bottom portion only of the root crown from the remaining portion of each green onion or removing a substantial portion of the roots; and packaging the green onions in a container, wherein the green onions are secured by the top portion at the time of applying the abrupt jarring force in a downward the direction substantially opposite the top portion, the green onions are transported to the clamp in a direction generally perpendicular to a path of travel of the clamp. 
     
     
       21. A method of processing green onions having bulbs including root crowns comprising: securing providing a clamping member; providing a pair of liked sized reversely rotating members spaced a first distance from the clamping member spaced a first distance from the clamping member; clamping a top portion of each of the green onions with the bottom of their root crowns spaced the first distance from the clamping member; clamping a top portion of each of the green onions with the bottom of their root crowns spaced the first distance from the clamping member; moving the secured clamped green onions in a generally vertical disposition with their root crowns disposed adjacent to the rotating members to cause the extending roots to move into engagement with a pair of like sized reversely the nip of the rotating members spaced a short distance from the root crowns; driving the rotating members sufficiently to apply an abrupt jarring force to a bottom portion of each of the green onions acting substantially in the direction opposite the top portion and in line between the top and bottom portions of each one of the green onions to rip apart a root crown to separate a bottom portion only of the root crown from the remaining portion of each green onion or removing a substantial portion of the roots as soon upon engaging the rotating members; wherein the green onions are secured by the top portion at the time of applying the abrupt jarring force, the green onions are transported to the rotating members in a direction generally perpendicular to an axis of each of the rotating members.
