A mill includes a first mill having a first grinding region, a second mill having a second grinding region opposed to the first grinding region and provided to be rotatable relatively to the first mill, and a heat radiation mechanism which is provided in at least one of the first mill and the second mill and radiates friction heat generated as a result of rotation of the first mill and the second mill relative to each other, and the heat radiation mechanism is provided in a portion except for the first grinding region and the second grinding region.

A grinding mill or seasoning grinder for grinding seasonings includes a stator and a rotatably mounted rotor having a base body with a shape of a truncated cone, where the rotor concentric to the stator. The stator and the rotor each include milling projections which are, at least in some sections, convexly curved in cross-section and the surfaces of milling projections are devoid of discontinuities that include edges or undercuts.

A foodstuff preparation device may include a roasting chamber having grinding funnel configured for communicating a foodstuff, having a pre-ground particle size, between two or more grinding stones, such as a first grinding stone and a second grinding stone. A grinding motor may be configured to motivate the foodstuff between the two or more grinding stone so that the foodstuff exits from between a first grinding stone and second grinding stone with a first ground particle size, the first ground particle size smaller than the pre-ground particle size. Generally, the device may be configured to prepare foodstuffs, such as sesame seeds, by roasting and grinding them to produce Tahini, or any other similar prepared food. Optionally, the foodstuff may be communicated into the grinding funnel from a dispensing funnel or from a roasting cavity having a heating element configured to govern the temperature of the roasting cavity.

An herb grinder comprising a receptacle grinding for receiving herbs and an insertable grinding member for being inserted into the receptacle grinding member. The receptacle grinding member comprises a receptacle grinding surface and a peripheral wall structure circumscribing the receptacle grinding surface. The insertable grinding member comprises an insertable grinding surface for rotatably interfacing with the receptacle grinding surface. The grinding surfaces comprise define a respective plurality of elongate grooves forming a respective contiguous protruding structure therebetween. Impartment of a mutual rotational movement of the insertable member within the receptacle grinding member provides for grinding herbs between the interfacing grinding surfaces by the grinding action of the respective contiguous protruding structures thereof.

The invention relates to a grinder for grinding coffee beans. The grinder has a first grinding tool and a second grinding tool which form a grinding gap and are rotatable relative to each other to grind coffee beans in the gap. A force generation device is arranged for applying a force, which is adjustable during operation, to one or both of the first grinding tool and second grinding tool, which force is transferrable to the coffee beans. The invention also relates to a method for grinding coffee beans with the grinder for preparing a hot beverage.

The present invention involves a system and method for grinding herbs, tobacco, marijuana and the like. The toothless herb grinder system comes in two preferred embodiments one of two piece and one of four pieces. The first embodiment of the toothless herb grinder system herein is comprised of two textured halves used for the compression and grinding process. The upper and lower halves are toothless, as they are carved with maze pattern system to shred the herbs placed in the grinder. The upper half is made of a convex maze pattern. The lower half is concave and the maze pattern is carved at the bottom of an internal bore. The material to be ground is placed and received at the bottom of the lower half. The second embodiment of the toothless herb grinder system herein is comprised of a top member, two tubular housing members and a bottom lid member. The top member is made of a convex maze pattern. The first tubular housing member having a grinding disk in the middle of its internal bore. The material to be ground is placed in the first tubular housing member, on top of the grinding disk. This construction provides an increased rapidity, uniformity and fineness of the grinding, when compared to grinders using a vertical teeth system

A tobacco grinder allowing direct transfer of ground tobacco to a smoking implement to eliminate waste includes an upper cover, a middle cover, and a material receiving base. The upper cover is rotatably positioned at one end of the middle cover the material receiving base is detachably connected to the end of the middle cover. A space between the upper cover and the middle cover defines a grinding cavity. A filter hole is defined on the middle cover, and a discharge hole is defined on the material receiving base, forming an escape path for tobacco which has been ground into particles. A sealing member is detachably coupled to the discharge hole, thus the discharge hole can be closed or opened. The ground tobacco can be directly transferred as required into the electronic cigarette.
