Description

Technical field

[0001] The present invention relates to a device for crushing material to be ground according to the preamble of claim 1, in particular in the sense of tearing and simultaneously grinding and milling. State of the art

[0002] Typical pepper and spice mills consist of a conical grinding mechanism, which is attached to or integrated into the lower end of a grinding container. The grinding mechanism itself comprises a grinding cone and a precisely fitting grinding ring. The grinding cone can be moved towards or away from the grinding ring by means of a spring-loaded pull rod. This movement creates a small or large grinding gap between the cone and the ring. This gap determines the size of the ground spice that emerges from the container (mill) after grinding.

[0003] Such commercially available spice, pepper or salt mills all have a plastic, die-cast aluminum, stainless steel or ceramic grinding mechanism and are only suitable for limited use with spices and seeds.

[0004] Other spice mills for both dry and fresh spices are so-called cutting mills or spice cutters. Instead of a grinding mechanism, these devices have a grinding or spice container with razor-sharp blades of varying shapes and sizes at the bottom. Horizontal rotation sets these blades in motion, cutting the spices, which then emerge through a perforated plate in the base.

[0005] Other spice or mortar graters consist of a porcelain bowl with a textured surface, on which fresh herbs like ginger or fruits like limes or bergamots can be ground or crushed by hand. Some of these mortar graters also include a pestle, which is used to crush herbs and seeds between the bumps on the textured porcelain surface. Coarse or fine grinding and / or fine milling is not possible with these types of graters.

[0006] Pepper and spice graters made of cast iron are also known. These graters, lacking knobs or teeth, allow the material to be churned and ground. The horizontal inner surfaces of the facing grinding surfaces of these graters are cast with a wavy pattern and have a small, precisely defined grinding gap, preventing the upper and lower parts from touching. Peppercorns and other peppercorns can be ground by pressing and twisting. These cast iron spice graters cannot grind or crush fresh herbs, soft herbs, or small seeds, as these become trapped in the indentations of the waves. Larger quantities of herbs also cannot be churned or processed due to the wavy shape of the grinding surfaces. Since these are exclusively cast iron devices, they are also unsuitable for grinding salt. Description of the invention

[0007] The present invention is based on the objective of eliminating the aforementioned disadvantages and creating a device which is particularly suitable for processing a wide range of fresh spices, dried spices, small and large kernels or hard grinding materials such as salt, nuts, allspice, cloves, etc., which cannot be processed with known hand mills or spice mills of any kind.

[0008] According to the invention, the aforementioned problem is solved in accordance with the preamble of claim 1 in conjunction with the characterizing features. Advantageous embodiments and further developments of the device according to the invention are specified in the dependent claims. Brief description of the drawings

[0009] Further objectives, features, advantages and application possibilities of the device according to the invention will become apparent from the following description of an exemplary embodiment with reference to the drawings.

[0010] The drawings show Fig. 1 an exploded view of the device according to the invention in an advantageous embodiment; Fig. 2 the device according to the invention in an advantageous embodiment in section; Fig. 3a and Fig. 3b as well as 3c and 3d the friction discs according to the invention in an advantageous embodiment from below and in a top view. Implementation of the invention

[0011] As from Fig.As can be seen in Figure 1, the device 1 according to the invention consists of a lower friction disc 11' fixedly mounted within a cylindrically designed grinding material intake 10 and an upper friction disc 11'' arranged on a cylindrically designed grinding material plunger 12 which can be inserted precisely into the grinding material intake 10 at a defined depth and is rotatably mounted on the grinding material intake 10 and is equipped with a handle part 121, wherein the two friction discs 11', 11'' together form a grinding gap S supplied with grinding material, wherein an annular spacer 13 is slidably mounted on the grinding material plunger 12 for the grinding material intake 10.

[0012] The present invention is characterized in that several spaced-apart and circularly arranged receptacles 100 are formed on the upper side of the material intake 10, in which several spacer profiles 130, correspondingly formed on the spacer element 13 with the receptacles 100, can be received. In the assembled state of the device 1, the spacer element 13 is arranged between the handle part 121, which is arranged on the material plunger 12, and the upper edge 101 of the material intake 10, and forms a corresponding, definable distance. Increasing the distance between the handle part 121 and the upper edge 101 of the material intake 10 simultaneously increases the grinding gap S.

[0013] In a particularly advantageous embodiment of the invention, several receptacles 100 with different depths and / or several spacer profiles 130 corresponding to the receptacles 100 with different heights or lengths (depending on orientation) are formed on the spacer element 13, wherein the height in this case refers to the longitudinal direction L of the device 1.

[0014] For coarse material and larger quantities of herbs, etc., the ring-shaped, height-adjustable spacer 13 on the material holder 10 can be horizontally rotated and repositioned, where it is inserted into the shorter recesses 100 of the material holder 10 with its profiled spacer profiles 130. Inserting the spacer 13 into the shorter recesses 100 of the material holder 10 increases the distance to the lower, facing grinding disc 11' in the material holder 10. This increased grinding gap S between the upper and lower grinding discs 11', 11'' makes it possible to obtain a second, larger air gap with the same material holder 10 and the same grinding plunger 12.By inserting the spacer 13 into the elongated recesses 100 of the grinding material intake 10, the distance between the lower friction disc 11' and the upper friction disc 11'' is reduced to the fixed minimum grinding gap S.

[0015] The grinding of the spice is now carried out by the counter-rotating grinding discs 11', 11'', which tear and simultaneously grind the spice through contact with the upper and lower rows of teeth 111. The opposing rows of teeth 111, by virtue of their shape and arrangement, cause a scoop-like and continuous circulation of the spice. Depending on the duration of these pressure-rotation movements, the spice is ground more or less finely, resulting in a coarser or finer grind.

[0016] Neither the grinding material intake 10 nor the precisely fitting grinding material plunger 12 are provided with outlet openings. The spice is firmly enclosed between these two grinding discs 11', 11'', which rotate back and forth against each other, and is continuously processed by the grinding disc teeth 111, thereby being continuously reduced in size and ground.
