Abstract

The present disclosure is directed to systems and apparatus for grinding spices and grains. One system includes a mill for grinding a spice or grain material, comprising a body and a handle rotatably coupled to the body. The handle is also coupled to an input of a speed boost assembly. An output of the speed boost assembly is coupled to a grind assembly, which includes a rasp. The speed boost assembly is configured to cause the rotational frequency of the rasp to be greater than a rotational frequency of the handle.

Claims (29)

1. A mill for grinding a spice or grain material, comprising:

a body;

a handle rotatably coupled to the body;

the handle also coupled to an input of a speed boost assembly;

an output of the speed boost assembly being coupled to a grind assembly;

the grind assembly including a rasp;

the speed boost assembly configured to cause a rotational displacement of the rasp to be greater than a rotational displacement of the handle.

2. The mill of claim 1 , wherein the speed boost assembly is a planetary gear train.

3. The mill of claim 2 , wherein the planetary gear train has a gear ratio between about 1.2:1 and about 3:1.

4. The mill of claim 2 , wherein the planetary gear train has a gear ratio of about 2.125:1.

5. The mill of claim 2 , wherein the planetary gear train includes a ring gear, a sun gear, and at least one planet gear;

wherein the ring gear is fixedly coupled to an interior of the handle to rotate as a unit therewith.

6. The mill of claim 5 , further comprising a carrier coupled to the body and the at least one planet gear rotatably coupled to the carrier.

7. The mill of claim 1 , further comprising a turn knob assembly;

the turn knob assembly comprising the handle and the speed boost assembly;

wherein the speed boost assembly is contained within an interior of the turn knob assembly.

8. The mill of claim 7 , wherein the turn knob assembly is releasably coupled to the body without requiring disassembly of any other parts of the mill.

9. A mill for grinding a spice or grain material, comprising:

a body;

a grind adjuster including at least one set of stepped detents and being rotatable between a first and a second position;

a follower coupled to a grind shaft, the follower riding on the stepped detents;

a rasp having a rasp grinding surface and being coupled at an end of the grind shaft; and

a grinder ring coupled to the body and having a ring grinding surface;

wherein the rasp is operatively positionable between at least a coarse spacing and a fine spacing;

wherein when the grind adjuster is in the first position, the rasp grinding surface is at a coarse spacing from the ring grinding surface and when the grind adjuster is in a second position, the rasp grinding surface is at a fine spacing from the ring grinding surface; and

wherein rotation of the grind adjuster relative to the body causes the follower to move between a first detent and a second detent.

10. The mill of claim 9 , wherein the grind adjuster includes a pair of radially opposed stepped detents.

11. The mill of claim 10 , further comprising an adjuster frame;

the adjuster frame including a pair of radially opposed followers.
