First Claim
1. An apparatus for the comminution of a botanical feedstock, the apparatus comprising:
- (i) a vessel having a top and a bottom, the bottom comprising a first feedstock outlet;
(ii) a screen positioned in the vessel above the first feedstock outlet and spaced from the top of the vessel, the screen having an upper surface and a lower surface; and
,(iii) a blade rotatably mounted above and generally parallel to the screen and configured to be rotated in a direction of rotation, the blade having;
a) a radial blade length that extends in a radial direction between an axis of rotation of the blade and a blade tip;
b) a leading side, at least a portion of the leading side having a cutting edge; and
c) a trailing side in the direction of rotation, at least a portion of the trailing side having a downwardly extending trailing portion, the downwardly extending trailing portion having a lower edge that extends in the radial direction, the lower edge having a plurality of discontinuities,wherein the cutting edge is spaced from the upper surface of the screen by a first distance and a lowermost portion of the lower edge is spaced from the upper surface of the screen by a second distance.

Abstract
An apparatus for the comminution of a botanical feedstock includes a vessel, a screen positioned in the vessel above a first feedstock outlet and spaced from the top of the vessel, and a blade rotatably mounted above and generally parallel to the screen. The blade has a leading side, a trailing side, and a radial blade length. At least a portion of the leading side has a cutting edge and at least a portion of the trailing side has a downwardly extending trailing portion. The downwardly extending trailing portion has a lower edge having a plurality of discontinuities along a radial length of the trailing portion. The cutting edge is spaced from the upper surface of the screen by a first distance and a lowermost portion of the lower edge is spaced from the upper surface of the screen by a second distance.
