Description

Technical field

[0001] The invention relates to a mill according to the preamble of claim 1. State of the art

[0002] Such spice seed mills are already known and used in a variety of forms and designs. For example, DE 1 372 189 U1 discloses a nutmeg mill in which the nutmeg to be ground is pressed by means of a spring mechanism in a tube onto a rotating grinding surface in the form of a drum.

[0003] Reference is further made to DE 76 15 837 U1, which describes a nutmeg mill with a housing. The housing of the nutmeg mill has a receiving chamber open towards the bottom of the housing for a nutmeg, with a grating disc that closes the receiving chamber and is detachably attached to the bottom of the housing, with a claw that is rotatable in the receiving chamber and displaceable perpendicular to the grating disc, and which is subject to a spring force directed against the grating disc, and with a rotary handle arranged on the top of the housing and connected to the claw by a shaft, wherein the claw and the shaft are formed in two parts, and the claw is axially displaceable on the shaft end projecting into the receiving chamber and is rotationally fixed to the shaft end, wherein the claw is pressed towards the grating disc by a spring and secured against being pulled off the shaft end by a stop.

[0004] Reference is also made to DE 7 145 448 U1, which also discloses a nutmeg mill, a nutmeg mill whose wall and in particular the bottom surface is closed off by a preferably disc-shaped closing plate equipped with outlet openings for the ground material and a grinding device, against which the nutmeg is pressed by spring force when an actuating shaft is turned, wherein the closing plate has an inwardly curved grinding iron which consists of one or a number of grinding iron areas to which corresponding outlet openings for the ground material are assigned.

[0005] Finally, reference is made to DE 10 2018 005 499 A1, which discloses a nutmeg grating box. This box comprises a grating surface with metal or at least hard sliding rails on its long sides, on the left and right sides, on which a bench is moved back and forth. On the bench is a cylindrical funnel containing a spring and, on its underside, a concave, perforated base plate with sharp points. This base plate is used to move the nutmeg placed on the grating surface back and forth, with the funnel being held in place by the fingers at the retaining knobs. Object of the invention

[0006] The object of the present invention is to overcome the disadvantages of the prior art. In particular, a spice seed mill is to be provided that does not require a spring-loaded pressing mechanism for the spice seed, such as nutmeg, while achieving a similar grinding result. Solution to the task

[0007] The features according to claim 1 lead to the solution of the problem.

[0008] Advantageous embodiments are described in the dependent claims.

[0009] The mill according to the invention for hard foods is used for grinding nutmeg, walnuts, hazelnuts, coffee beans, other seeds, or, for example, hard cheese. It is irrelevant whether the listed spice seeds are hard due to drying or roasting, or softer because they are unroasted. Especially with expensive seeds like nutmeg, complete use is important. However, injuries often occur when trying to guide the ever-smaller remaining piece along a grater by hand. Accordingly, nutmeg is ground or crushed using spring-loaded constructions known from the prior art. The mill according to the invention is therefore particularly preferably a mill for nutmeg.

[0010] The mill according to the invention consists of a housing and a cutting grinding mechanism, the cutting grinding mechanism being radially rotatable within a cylindrical receptacle in the housing. The housing also features a spice seed inlet recessed into it. This spice seed inlet is designed to form a helical cone within the housing, into which the cylindrical receptacle intersects. A helical cone is a spirally winding helical structure that takes on a conical shape due to the intersecting cylindrical receptacle. This conical shape results from the fact that the helical structure is interrupted by the intersecting section, and the position furthest from the beginning of the helical structure resembles a cone tip.

[0011] According to the invention, the cutting mill is a cylindrical tube, wherein the cylindrical tube has cutting openings projecting outwards on a tube circumference and the cylindrical tube has an outlet at one end and an actuating device at the other end, wherein the cylindrical tube is arranged to rotate radially in the cylinder receptacle.

[0012] The special shape of the helical cone described above advantageously ensures that the hard foods are held by the protruding cutting openings without snagging or jamming, are chopped, and are simultaneously drawn in further during the chopping process.

[0013] The actuating device can be connected to a rotary lever in a rotationally fixed manner. Rotationally fixed means that the rotation of the rotary lever is transmitted directly to the actuating device and thus directly to the cylinder tube, causing it to move radially.

[0014] The actuating device can be a screw body, wherein the screw body is formed centrally as part of a top plate formed at the other end of the cylinder tube. The top plate closes the other end of the cylinder tube.

[0015] The top plate can also have a circular hole recess, in which, when installed, a plunger of the rotary lever is inserted into the circular hole recess, creating a rotationally fixed connection between the rotary lever and the cylindrical tube. The rotary lever can be axially secured, for example, by a nut. The rotary lever has a screw receptacle, allowing it to be pulled over the screw body and secured against axial slippage by the nut. The plunger then slides into the circular hole recess, causing the cylindrical tube to rotate radially with the rotary lever.

[0016] Furthermore, the cutting openings are designed such that they are blades projecting from the circumference of the tube, with openings arranged in front of them. The material to be ground can slide through these openings into the interior of the cylindrical tube and fall out through the outlet.

[0017] The housing body can be made of materials such as wood or plastic. A construction from a metal material is also possible in principle.

[0018] The cylinder receptacle is an opening that extends through the housing body. It has a circumference that allows the cylinder tube to rotate radially within the receptacle.

[0019] In its installed position, the housing body has a metal cover, the metal cover having a first recess congruent with the spice seed inlet and a second recess congruent with the actuating device located at the other end. "In its installed position" means when all essential features of the mill are assembled in such a way that hard foods, such as nutmeg, could be ground.

[0020] The cutting openings are arranged linearly side-by-side on the surface of the cylindrical tube, running from one end to the other. This creates rows of cutting openings, one above the other, with each row offset from the others. This ensures optimal grinding, as one row of cutting openings is always holding the nutmeg while the other is cutting, thus freeing the previously cutting row and releasing the ground nutmeg.

[0021] In one embodiment, the cylinder tube has radially circumferential, projecting running surfaces at one end and at the other end. This ensures smooth rotation of the cylinder tube in the cylinder receptacle. Character description

[0022] Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings; these show in: Fig. 1 a cutaway side view of a mill according to the invention; Fig. 2 a top view from an oblique angle onto a housing body; Fig. 3 a cutaway side view of the housing body made of Fig. 2. Example of implementation

[0023] The Fig. Figure 1 shows a mill 1 according to the invention. It consists of a housing body 2 and a cutting mill, wherein the cutting mill can be inserted radially rotatably into a cylinder receptacle 3 of the housing body 2, wherein the housing body 2 forms a spice seed inlet 4.

[0024] The cutting mill is a cylindrical tube 5, wherein the cylindrical tube 5 has protruding cutting openings 7 on a tube circumference 6.

[0025] The cylinder tube 5 has an outlet 8 at one end and an actuating device 9 at the other end. The cylinder tube 5 is arranged to rotate radially or rotatably in the cylinder receptacle 5, wherein the spice seed inlet 4 in the housing body 2 forms a helical cone, into the course of which the cylinder receptacle 3 intersects.

[0026] The actuating device 9 is connected to a rotary lever 10 in a rotationally fixed manner.

[0027] The actuating device 9 can, for example, be a screw body (not shown in detail) which is formed centrally as part of a top plate formed at the other end of the cylinder tube 5.

[0028] The upper plate has a circular hole recess (not shown in detail), in which, when installed, a plunger of the rotary lever 10 is inserted into the circular hole recess. This ensures a rotationally fixed connection between the rotary lever 10 and the cylindrical tube 5.

[0029] The cutting openings 7 are blades that are flared or protruded from the circumference of the tube 6, with openings arranged in front of them.

[0030] The cylinder receptacle 3 is an opening extending through the housing body 2.

[0031] In its installed position, the housing body 2 has a metal cover 11, the metal cover 11 having a first recess 12 congruent with the spice seed inlet 4. Congruent means that a functional relationship exists such that, for example, a nutmeg can slide through the first recess 12 into the spice seed inlet 4. A second recess 13 is also present, which is congruent with the actuating device 9 arranged at the other end.

[0032] Furthermore, the cutting openings 7 are arranged linearly next to each other from one end to the other end, thereby forming rows of cutting openings 14, 15, whereby the rows of cutting openings 14, 15 are again arranged offset from each other.

[0033] Furthermore, the cylinder tube 5 has radially circumferential protruding running surfaces at one end and at the other end of the cylinder tube 5.
