 DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS OF THE INVENTION
According to a disclosed embodiment of the present invention, there is provided 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.
By separating the roots or portions thereof at the root crown from the vegetables, the remaining portion of the root crown attached to the bottom of the bulb of the vegetable, prevents or at least greatly tends to eliminate the unwanted telescoping growth of the vegetable after the roots are removed. According to the disclosed embodiments of the present invention, the method and apparatus as disclosed herein may help to prevent or to inhibit such unwanted growth for some applications, and thus may promote longer shelf life of the packaged vegetables.
Referring now to the drawings, and more particularly FIG. 1 thereof, there is illustrated an embodiment of a vegetable processing method generally indicated at 10. The method 10 includes, as indicated at box 12, applying opposing forces to the vegetables to separate the roots at the root crown from the remaining portion of the vegetable structure. In so doing, the opposed forces tend to pull apart or otherwise take apart the root crown. The remaining portion of the root crown tends to prevent the unwanted telescoping of the vegetable. If the root crown is not able to be pulled apart, the roots tend to break apart or be torn off leaving the entire root crown intact to serve to help protect against the undesirable telescoping effect.
The applying of the opposing forces includes applying force to the bottom portion of each one of the vegetables below the intersection of the root crown and the bulb in opposition to force applied to the top portion of the vegetable. As a result, the bottom portion is separated from the vegetable at the root crown. The bottom portion may include a broken off portion of the root crown with all of the root attached thereto, or may include torn off portions of the roots only. In this manner, the remaining portion of the root crown stays in tact with the vegetable to prevent or inhibit unwanted telescoping growth.
As indicated at box 14, the de-rooted vegetables are then grouped together and packaged. The packaged products are typically then transported to where they are to be sold.
Considering now one embodiment of the method 10 with reference to FIG. 2, the vegetables such as green onions are first singulated as indicated at box 16. The singulated vegetables are then supported from their upper portion individually as indicated at box 18 to be suspended vertically. For purposes of this description of an example of the disclosed embodiment, assume that the vegetable being processed is a green onion. Also, while a vertical disposition is described herein, other dispositions may also be employed such as horizontal or angular.
The vertically supported vegetables are then washed as indicated at box 21. In this regard, the vertically supported green onions are transported past a washing station. The foreskins are then peeled from the green onions as they are moved past a peeling station as indicated at box 23.
As indicated at box 27, the roots of the peeled green onions are each then moved seriatim into engagement with a first de-rooter such as a pair of rotating members. The de-rooter provides a downward force on the roots of the green onions in opposition to the force applied at the upper portion of the green onion for supporting it in a vertical hanging disposition. The opposing forces cause the roots to be separated from the remaining structure of the green onion at the root crown. In this regard, the root crown either is ripped apart or otherwise becomes separated, or the bottom portions of the roots are torn off leaving the root crown intact. Thus, either all or a substantial portion of the green onions being processed have their roots either removed entirely or a substantial portion of the roots are torn away, to leave either all or a substantial portion of the root crown intact to prevent or at least to inhibit the unwanted telescoping growth.
The green onions are then moved into engagement with a second de-rooter such as a pair of rotating members as indicated at box 29 so that in the event that the roots have not been removed, they will undergo a second de-rooting operation similar to the method described in connection with the first de-rooter as indicated at box 27.
The separated portions of the green onions are then discarded as indicated at box 32. The de-rooted green onions are then transported to a washing station for washing them as indicated at box 34. The washed green onions are then grouped as indicated at box 36, and the groups of green onions are then packaged as indicated at box 38.
Referring now to FIGS. 3 and 4 of the drawings, there is shown a de-rooter 41, which is constructed in accordance with an embodiment of the invention, and which may be used in connection with the method of FIG. 1. The de-rooter 41 is used to remove the roots from a series of green onions such as a green onion 43 as they are being transported seriatim to and past the de-rooter 41. The green onion 43 includes a stalk or tube 45 at the upper portion thereof and a bulb 47 having a root crown 49 with roots 52 extending from the bottom portion of the green onion 43.
A clamp such as a foam clamp 54 in the form of a foam conveyor belt may be used to support the green onion 43 by clamping the stalk 45 to permit it to hang vertically from the clamp 54. The foam clamp 54 includes a pair of foam clamp members or belts 56 and 58 which grips and holds opposite sides of the stalk 45 to support the onion 43 in a generally vertical disposition as it is moved to and past the de-rooter 41. The conveyor clamp 54 translates the green onion 43 to the rotating de-rooter 41 for root removal on the fly. The de-rooter 41 includes a pair of rotating members in the form of pinch rollers 61 and 63 mounted for rotation about the respective horizontal axes 65 and 67. In this regard, the rollers 61 and 63 are driven about their respective horizontal axes in opposite directions.
The roots 52 are moved into engagement between the closely spaced rollers 61 and 63, which pull downwardly on the roots 52 to provide an opposing force relative to the force applied by the clamp 54. The opposing forces may separate or rip apart the root crown 49 as indicated in FIG. 4. Alternatively, if the root crown 49 does not fracture, the roots 52 may tear apart under the opposing longitudinal forces, thus providing roots of a shorter length without removing any portion of the root crown. The separated portion of the root crown 49 and the roots 52, or just the torn off portions of the roots, are discharged downwardly from the rotating pinch rollers 61 and 63 and fall under the force of gravity for discarding them.
Referring now to FIG. 5, there is shown another de-rooter 69, which is constructed in accordance with another embodiment of the invention and which is also useful in connection with the method 10 of FIG. 1. The de-rooter 69 is similar to the de-rooter 41, except that the de-rooter 69 does not include rollers.
The de-rooter 69 facilitates the removal of roots from green onions such as a green onion 72 having a bulb 74 with a root crown 76 having roots 78. The de-rooter 69 includes, instead of a pair of pinch rollers, a pair of rotating members in the form of meshing gears such as the spur gears 81 and 83 mounted for rotation about the respective horizontal axes 85 and 87. One of the meshing gears is a driving gear, and the other gear is a driven gear. The driving gear is activated by a suitable motive device (not shown), such as a motor.
The meshing gears 81 and 83 engage the roots 78 in a similar manner as the pinch rollers 61 and 63 of FIG. 3. Thus, the meshing gears 81 and 83 forcibly pull on the roots 78 downwardly in opposition to the force applied to the upper portion (not shown) of the green onion 72 to cause the roots 78 to separate from the remaining structure of the green onion 72 at the root crown 76 along a separation line 89.
Referring now to FIGS. 6, 7 and 8, there is shown a de-rooter 92, which is also constructed in accordance with still another embodiment of the invention, and which is suitable for use with the method 10 of FIG. 1. The de-rooter 92 may be used in connection with green onions such as a green onion 94 having a bulb 96 with a root crown 98 and roots 101. The de-rooter 92 includes a moveable clamp such as an articulated horizontal V-shaped clamp 103 having a pair of clamp members 105 and 107 are pivotally mounted together at a vertical axis 109. The roots 101 of the green onion 94 are moved into engagement with the V-shaped clamp 103, and in so doing, the clamp members 105 and 107 move pivotally toward one another to grasp the roots 101 therebetween. Once clamped in place as indicated by the phantom lines shown in FIG. 6 and in solid lines in FIG. 8, a vertically movable support 112 (FIG. 7) abruptly moves the clamp 103 vertically downwardly to apply an abrupt jarring force in opposition to the force applied at the upper portion of the green onion 94 being held in a manner similar to the clamp 54 of FIG. 3. The movement of the support post 112 causes the clamp 103 to move abruptly downwardly by means (not shown) such as a piston cylinder assembly (not shown), as indicated in broken lines in FIGS. 7 and 8, thereby causing the root crown 98 preferably to be pulled apart and to separate along a separation line 114. Alternatively, in the event that the root crown 98 does not fracture, the bottom portions of the roots 101 are ripped away at the clamp 103.
The term “singulated” as used herein may mean “singled out,” and “singulating” may mean “one at a time.”
Further modifications will also occur to those skilled in this art, and such are considered to fall within the spirit and scope of the invention as defined in the appended claims.
