Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a method for manufacturing a mortar using powdered powder of matcha, grains, medicinal herbs, minerals, etc.

``Conventional technology'' Conventionally, this seed mill for matcha, etc. uses stone materials such as granite, sandstone, and welded tuff as raw materials,
There are two methods: one is to do it manually using tools such as a knife and a sharpener, and the other is to use stone as a raw material and use machining methods such as lathe processing and diamond cutting.
In some cases, it is said that there is also a method of sequentially providing a divided back surface member or front surface member in a circular shape on the back surface of the upper and lower dies.

``Problems to be Solved by the Invention'' As detailed above, conventionally, when manufacturing this type of mortar by hand, it is a difficult task that requires considerable skill and precision, and it also takes a long time to manufacture. Furthermore, there are problems such as difficulty in achieving precision during manufacturing. Also, various precautions are required in manufacturing the material. On the other hand, when manufacturing by machining, the speed of manufacturing can be achieved, but since stone is used as the raw material, a certain level of skill is required for various types of processing, and there are problems such as difficulty in achieving precision during manufacturing. Ta.

``Means for Solving the Problems'' Therefore, the present invention is manufactured by machining and using iron as the main raw material in order to simplify manufacturing and easily ensure accuracy. The method is to divide the upper and lower dies into upper and lower dies, respectively, and the back and surface parts, each of which is provided with a separate ceramic thin film, and to assemble them into one piece. A back surface member provided with a ceramic thin film constituting the back surface is divided into several fan-shaped back surface member pieces when viewed from above, and a groove consisting of a main groove and a sub-groove formed by these several sections is formed. A back surface member having a through hole is sequentially provided in an annular manner on the back surface of an iron upper mortar member to constitute an upper mortar, while a surface member comprising a ceramic thin film forming the surface of a lower mortar is provided. It is divided into several fan-shaped surface member pieces when viewed from above, and the surface member pieces each having grooves consisting of a main groove and a sub-groove are placed on a lower mill member made of iron. These are arranged in an annular manner on the surface to form a lower mill, and in the center of this lower mill a core rod consisting of an iron core and a ceramic thin film surrounding the core is erected, and the upper mill is inserted into this core rod. The upper die is mounted on the lower die by inserting a hole therein, and a flattened diamond-shaped concave portion is formed between the upper die and the upper die.

"Embodiment and Effect" Next, an embodiment of the present invention will be described based on the drawings. 1 is a core 1a made of iron, and a ceramic thin body is applied by thermal spraying or pasting around the core 1a except for the back surface of the core 1a. Ceramic thin film 1 provided as
This is an upper mortar member having an insertion hole 2 in the center, which is formed by b, and a back member having a ceramic thin film provided on the back surface of the upper mortar member 1 by a method such as ceramic spraying or adhesion of a ceramic thin body. Fractionate 3,
Several back member pieces 4a are fan-shaped when viewed from above,
4b...4n are sequentially provided in a ring shape. That is, as shown in FIG. 5, a back member piece 4a is provided on the back surface of the upper mill member 1, and a next back member piece 4b is provided adjacent to this back member piece 4a. By repeating such steps and concealing the back surface with the back surface member pieces 4a, 4b, . . . 4n, the upper mill is constructed. A groove consisting of a main groove 5 and a sub-groove 6 is provided in the back member pieces 4a, 4b, . . . , 4n. The method of providing the back member pieces 4a, 4b...4n on the back surface of the upper die member 1 is by screwing,
Either adhesion, fitting, etc. may be used. 8 is a core 8a made of iron, and a ceramic thin film 8b provided around the core 8a by ceramic spraying or adhesion of a ceramic thin body except for the surface thereof, with a through hole 9 for a core rod in the center. This is a lower mill member formed by opening the lower mill member 8. On the surface of this lower mill member 8, a ceramic thin film is provided by a method such as ceramic spraying or ceramic thin film adhesion. Several fan-shaped surface member pieces 11a, 11b...1
1n are sequentially provided in a ring shape. That is, as shown in FIG. 10, a surface member piece 11a is provided on the surface of the lower mill member 8, and a next surface member piece 11b is provided adjacent to this surface member piece 11a. By repeating these steps, the surface is made into surface member pieces 11a, 11b...11n.
The lower millstone is constructed by concealing it with. Main grooves 12 are formed in the surface member pieces 11a, 11b...11n.
A groove consisting of a sub-groove 13 and a sub-groove 13 is provided. Furthermore, surface member pieces 11a, 11b...1 are provided on the surface of the lower mill member 8.
1n can be provided by screwing, gluing, or
Any method such as fitting is possible. A core 15a made of iron and approximately the lower half of the core rod 15, which is made by surrounding the core 15a with a ceramic thin film 15b made by ceramic spraying or the like, are inserted into the through hole 9 of the lower mill constructed as described above, and the lower half of the core rod 15 is inserted. The core rod 15 is raised on the mortar. By inserting the insertion hole 2 of the upper die into the upright part of the core rod 15, the upper die is mounted on the lower die, and a flat diamond-shaped bulge is formed between the upper and lower dies. A is constructed. In addition, the insertion hole 2 and the core rod 15
A gap B for insertion of tencha is formed between the two. Note that the front and back member pieces 4a, 4b,...4n, 11a, 11
b...11n may have a wedge-shaped cross section as shown in FIG. 8 may be donut-shaped. In this figure, the upper die member 1 and the back member pieces 4a, 4b, . . . , 4n are shown upside down. Other numbers of fractions are also possible, and the pattern of the grooves will vary depending on the direction of rotation of the die (clockwise).

To explain the usage of the matcha mortar as an example of this type of mortar constructed in this way, the motor 16
Turn ON and rotate the upper mill through the link machine groove 17. When raw tencha is placed on the upper mill in this state, this tencha is inserted into the gap B between the through hole 2 of the upper mill and the core rod 15, and as the upper mill rotates, the tencha is also rotated and lowered. It falls toward the mortar, but in this process, it is crushed by the ceramic thin films 1b, 15b of the upper mortar and the core rod 15, and moves downward. It is believed that by increasing the diameter of the core rod 15 downward and gradually narrowing the gap B as shown in the figure, the particles will be crushed even finer. Then, when the crushed tencha reaches the flat diamond-shaped bulge A formed between the upper and lower mortars, the crushed tencha is further finely crushed, so-called pulverization. In this case, since the grooves of the upper and lower dies overlap, as the upper die rotates, the main groove 12 and the auxiliary groove 13, which make up the groove of the lower die, are The grooves 6 overlap each other and move in the radial direction. Conversely, the main groove 12 and sub-groove 13 of the lower die overlap with each other and move in the radial direction below the main groove 5 and sub-groove 6 of the upper die. As a result, this main groove 5,
12. Sub-grooves 6, 13 The crushed tencha filled in the so-called grooves is sheared by the cross of these grooves and is pushed out in the radial direction. When it reaches the sliding part C consisting of the upper and lower dies, the upper mold slides slightly against the center line of this rubbing part C (the insertion hole of the upper mold). 2 and the core rod 15 due to the gap B between the upper mill and the sliding movement caused by this, the tencha is further finely ground.
Matcha is produced by being discharged from the peripheral tips of the upper and lower dies. As a drive device for the mill, although not shown, an output shaft of a motor may be connected to the lower end of the core rod to provide a downward drive method. In this case, the lower mill is fixed on the base, and the upper mill is rotated through the drive of a motor, and the upper mill and the core rod are configured to rotate together with a key or the like. The raw material tencha is made into matcha in the same order as in the above example. Also, other grains,
Medicinal herbs, minerals, etc. are similarly manipulated. Furthermore, the surface of the lower mill can be made flat, and the flat triangular shaped bulge A can be formed between the surface of the lower mill and the gently inverted bowl-shaped back surface of the upper mill, or the surface of the lower mill can be shaped like a gentle mountain. A modification example may be considered, such as forming a substantially curved bulge A by combining this gentle chevron-shaped shape and the gentle inverted conical shape of the upper mill.

``Effects of the Invention'' The present invention is a method detailed above, in which the upper and lower dies are each made of iron as the main raw material, and are divided into a lower dies, a back part with a ceramic thin film separated from it, and a front part. , since this is a method of assembling and integrating,
A mortar with a ceramic thin film for use with this type of matcha can be manufactured relatively easily, and standardized products can be mass-produced without requiring any skill. It is also superior in terms of accuracy, allowing for the production of high-quality matcha powder, etc., and can be expected to increase the number of rotations of the upper mill, which is useful for speeding up the process. Furthermore, since the cores of the upper and lower dies are made of iron, they have excellent strength, are less prone to breakage, and can be used for a long period of time. Furthermore, fine pulverization can be achieved using ceramic particles, and the production of high-quality powders such as matcha can be expected. In addition, by utilizing the wear resistance of the ceramic thin film, it is possible to apply pressure to the upper mill, for example with a weight, which is effective in producing powder of grains and other materials with a low oil content, allowing for finer pulverization. I think that the.
