Abstract: A machine for removing the calyces from the seed of a sorrel bud includes a smooth surfaced return drum rotatably mounted to a frame and a cutting drum rotatable about a cutting drum axle and mounted to the frame in a tandem relationship with the return drum. The cutting drum has a plurality of circumferential blades oriented perpendicular to the cutting drum axle and are substantially equally spaced one from another. The cutting drum in combination with the return drum defines a throat therebetween for receiving sorrel buds. A drive simultaneously rotates the return drum and the cutting drum to cut calyces from the seed of the sorrel bud.
