Abstract

A method for harvesting bast plants that have stalks, husks, and seeds. The method includes cutting the bast stalks from the bast plants and promptly receiving the bast stalks onto a first belt without retting the bast stalks. The method then orients at least a portion of the bast stalks on the first belt, the longitudinal axis of the at least a portion of the bast stalks being generally oriented in the direction the first belt is moving. The husks and seeds may be removed from the bast stalks. The bast stalk may be packaged.

Claims

1. A method for harvesting bast plants, the bast plants having stalks, husks, and seeds, the method comprising:

cutting the bast stalks from the bast plants with a cutting device of a harvester;

after cutting, receiving the bast stalks onto a first belt of the harvester;

orienting at least a portion of the bast stalks on the first belt of the harvester with a plurality of spaced tines extending toward the first belt to align a substantial majority of the bast stalks generally parallel to each other, the longitudinal axis of the at least a portion of the bast stalks being generally oriented in the direction the first belt is moving;

removing the husks and seeds from the bast stalks; and

packaging the bast stalks with the harvester.

2. The method of claim 1, wherein the orienting step further comprises moving at least one bar back and forth across the first belt in a direction generally perpendicular to the direction the first belt is moving, the at least one bar elevated above the first belt and having the plurality of spaced tines extending toward the first belt, wherein the movement of the at least one bar orientates at least a portion of the bast stalks.

3. The method of claim 1, further comprising

receiving the de-husked bast stalks on a second belt of the harvester;

and

orienting the de-husked bast stalks on the second belt of the harvester prior to packaging, the bast stalks being oriented in the direction the second belt is moving.

4. The method of claim 3, wherein orienting the bast stalks on the second belt of the harvester further comprises moving at least one bar back and forth across the second belt in a direction generally perpendicular to the direction the second belt is moving, the at least one bar elevated above the second belt and having a second plurality of spaced tines extending toward the second belt, wherein the movement of the at least one bar orientates the bast stalks.

5. The method of claim 1, further comprising compacting the oriented bast stalks with the harvester prior to packaging.

6. The method of claim 5, wherein the step of compacting further comprises presenting the bast stalks to a plurality of roller sets of the harvester, each of the roller sets of the plurality of roller sets of the harvester having at least one squeeze roller.

7. The method of claim 1, wherein the step of packaging further comprises baling the oriented bast stalks with a baler of the harvester.

8. The method of claim 1, wherein the step of removing further comprises passing the bast stalks through a plurality of roller sets, each of the plurality of roller sets having an upper roller proximate a lower roller.

9. The method of claim 1, further comprising transporting the bast stalks over a screen, the screen having a plurality of openings that are sized so as to permit the removed outer skin and seeds to pass therethrough.

10. The method of claim 1, wherein no decorticating of the bast stalks occurs subsequent to the steps of claim 1.

11. The method of claim 1, wherein decorticating of the bast stalks occurs subsequent to the steps of claim 1.

12. The method of claim 1, wherein no retting of the bast stalks occurs subsequent to the steps of claim 1.

13. The method of claim 1, wherein retting of the bast stalks occurs subsequent to the steps of claim 1.
