What is described is a new grinder, which serves to grind coffee beans and which is embodied as disk grinder. To improve the grinding process, the first and/or second grinding disk, respectively, encompass grinding surfaces that may define an angle of inclination, which may be in each case greater than 90? and smaller than 180?, relative to a tool reference plane.

The present invention relates to a drip coffee machine. The drip coffee machine according to an embodiment of the present invention comprises: a case; a hopper for accommodating coffee beans; and a grinder for receiving and grinding the coffee beans, wherein the grinder is coupled to the case in a detachable manner, and the grinder includes: a grinder body including a rotating burr; and a grinder driving part, which is connected to the grinder body and provides rotating force to the burr.

A bean grinder having a bean grinding chamber part, a dynamic grinding wheel, a static grinding wheel, and a residue removing plate. The bean grinding chamber part comprises a bean grinding chamber and a powder discharge channel. An inner wall of the bean grinding chamber is provided with a planar first inner wall disposed close to a powder discharge port and located at a rear side of the powder discharge port in a rotation direction of the dynamic grinding wheel. The first inner wall is tangent to a circle of the inner wall of the bean grinding chamber. An inner wall of the powder discharge channel comprises a second inner wall located at the side of the powder discharge port provided with the first inner wall, and the second inner wall is inclined outwards at a given angle a with respect to the first inner wall.

A grinder system facilitates transporting, dispensing, and storing ground herbs, spices, or tobacco after they have been ground.

A grinding device for grindable products includes movable and fixed grinding assemblies. The movable grinding assembly includes a rotationally integral casing and a grinder including a grinding cone with a grinding surface. The fixed grinding assembly includes a counter-grinder and a coupling member. The casing includes a cylindrical jacket and is closed at one end, including openings for dispensing a ground product. The counter-grinder has a hollow cylindrical body with an inner grinding surface. The grinder is inserted into the hollow cylindrical body of the counter-grinder to allow the respective grinding surfaces to cooperate. The coupling member includes an open ended cylindrical body connecting with the container and an adjustment portion cooperating with the casing for adjusting the movable grinding assembly with respect to the fixed grinding assembly. The grinder and the counter-grinder are substantially rigid, and the casing and the coupling member are substantially flexible.

To provide a grinder for realizing granularity stabilization while having easy maintenance.

A grinder including a rotation body 2 exhibiting an almost conical shape and having a rotation axis, the rotation axis passing a top of the almost conical shape and crossing a bottom face at a right angle, and a grinding mechanism, the grinding mechanism having a configuration for grinding an object to be ground by a stator body 3 exhibiting an almost cylinder shape and an inner face disposed opposite to a lateral face part of the rotation part 2 is provided, characterized in that a lateral face of the rotation body 2 and a surface of the inner face of the stator body 3 comprise concave/convex blades 20, the concave/convex blades 20 are formed as multi-stages along to a rotation axis direction, and the concave/convex blades of each stage are each separated along the rotational axis direction.

A grinding unit having a ring burr and a frustoconical burr that together delimit a grinding gap therebetween. A first angle between a first subset of curved teeth of the frustoconical burr and the first curved teeth of the ring burr provides a grinding gap having an angle smaller than a second angle between a second subset of curved teeth of the frustoconical burr and the first curved teeth of the ring burr. A geometrical outline taken through the cusps of the second curved teeth at the top end face of the frustoconical burr opposite the base is a square or rectangle. This grinding unit produces a ground product, such as ground coffee beans, with fewer turns than known grinding units and with less effort. The properties and qualities of the resulting ground products are superior to those obtained with conventional grinding units because flavor and aroma are retained.
