Description

TECHNICAL FIELD The present invention relates to a stamp mill for crushing raw materials for powder such as buckwheat flour and mustard flour.

2. Description of the Related Art Structure of the Prior Art and Problems Thereto So far, a stamp mill of a type in which a plurality of flaws are dropped down has been proposed and put into practical use. Japanese Patent Sho 61
In the one disclosed in Japanese Patent No. 320060, a plurality of ridges extending in the vertical direction are arranged in the same vertical plane.
Then, a thin is provided below the fox, and each fox drops into the vine, and the raw material is rubbed and crushed by each fox.

By the way, as is well known, buckwheat flour, mustard flour and the like have grades. For example, buckwheat flour includes first flour, second flour and third flour. The first powder is a white powder that contains only buckwheat and almost no skin. Strain the buckwheat flour raw material, crush it, and sift it.
White powder can be separated from the crushed raw material and taken out. This is the best powder. The raw material that has not been sifted is called Ichibankoudori, which is usually ground again and sifted. Then, the second powder is taken out from the sieve. The second powder contains some of the raw material, and is a little black. Further, the reconstitution of the second flour is crushed again, sieved, and the third flour is removed from the sieve.

However, in the case of the stamp mill disclosed in JP-B-61-2060, the raw material can be crushed and crushed by a plurality of crevices, and the crushing ability is large, but the raw material is thinned every time each crevice is dropped. It moves in the horizontal direction with, and it is unavoidable to move in the direction of arrangement of the ridges. Therefore, the raw materials of the powder cannot be squeezed uniformly in sequence, and some of them are smashed many times and some of them are not, and they are mixed with each other. Therefore, even if the raw material of buckwheat flour was crushed with this stamp mill and sieved to separate the first flour from the crushed raw material, the obtained powder was not a sufficiently white powder. There was a problem that the quality of the first powder was impaired because black powder was produced by the grains that were rubbed many times.

Furthermore, in the case of this stamp mill, it is not possible to grind each grade at the same time. Even if each grade is thrown into a different crease position, each grade is unavoidably mixed in the thin, and it is difficult to separate the grades after crushing. Therefore, it is necessary to crush only the original raw material with a stamp mill, then crush only the most powder return, and further crush only the second powder return, in addition to automating this. It was extremely inefficient and there was a demand for improvement.

Therefore, the present invention, in a stamp mill for crushing buckwheat flour, powdered raw materials such as mustard flour, solves the above-mentioned conventional problems, the raw material of the powder is slaughtered uniformly and crushed,
And for the purpose of simultaneously crushing different grades.

According to the present invention, according to the present invention, a plurality of ridges extending in the vertical direction are arranged in the same vertical plane, a thin portion is provided below the ridge, and each ridge is dropped into the thin ridge, In a stamp mill adapted to crush and grind raw materials, the thin is divided by a partition plate arranged between adjacent ridges, and a plurality of crushing chambers are formed by the partition plate and the thin, and A plurality of raw material charging ports are provided on one side of the vertical surface, and the raw material charging ports are connected to the crushing chambers,

Furthermore, this stamp mill has two partition plates (13), each partition plate (13) is arranged between each ridge (1), and each partition plate (13) divides the thin (3). ing. further,
Two side plates (14) are provided at both ends of the thin (3), and side plates (1
4), 3 crushing chambers with partition (13) and thin (3)
(15A), (15B), and (15C) are formed. Therefore, each tine (1) is housed in each crushing chamber (15A), (15B), (15C). As shown in FIG. 5, the ridge (1) is a plate having a constant thickness and has a width (W) corresponding to the width of each crushing chamber (15A), (15B), (15C). Side plate (14) is partition plate (13)
It has the same shape as.

Furthermore, in this embodiment, as shown in FIG. 3, three raw material inlets (16A), (16B), (16C) are formed in the upper plate (17) of the thin (3), and each crushing chamber ( It communicates with 15A), (15B), and (15C).
Furthermore, the thin edge (3) is provided with a side edge (18) of a certain height,
The outlets (19A), (19B), and (19C) of the two crushing chambers are provided on the reaction side of the side edge (18), and the crushing chambers (15A), (15B), and (15C) are connected to the outlets (19).
It is connected to A), (19B), and (19C) and connected individually. Further, three pipes (20) are provided below the thin (3), and outlets (19A), (19B), (19C) are connected to the pipes (20). Then, as shown in FIG. 4, the three shifters (21A),
(21B), (21C) is combined with a stamp mill, and each pipe
(20) is connected to each shifter (21A), (21B), (21C).
Furthermore, four pipes (22) are shifters (21A), (21B), (21C)
It is installed between the stamp mill and the stamp mill.The shifter (21A) is connected to the input ports (16A) and (16B) of the stamp mill, and the shifter (21B) and (21B)
C) is connected to the input port (16C) of the stamp mill. The shifters (21A), (21B), (21C) have a four-stage sieve 4
It is a stepped type. The pipes (20) and (22) are pneumatic transportation type using air flow.

In this stamp mill, for example, when the buckwheat flour raw material is put into the charging port (16A), this is introduced into the crushing chamber (15A), and the raw material is mashed and crushed by the knives (1) of the crushing chamber (15A). It In addition, the crushed raw material is thin (3) on the side edge (18).
Is introduced into the outlet (19A) and the pipe (20), rides on the air flow of the pipe (20), and is sent to the shifter (21A). Then, in the shifter (21A), the raw material is passed through a four-stage sieve, and the first powder is taken out from the shifter (21A).

Furthermore, in the shifter (21A), the large-grain raw material that did not cover the uppermost sieve was introduced into the pipe (22), riding on the air flow, sent to the stamp mill, and introduced into the inlet (16A), It is put into the crushing room (15A). Therefore, these are ground together with the original raw material. In addition, the shifter (2
In 1A), the one that did not cover the bottom sieve was introduced into the pipe (22), riding on that air flow, sent to the stamp mill, introduced into the inlet (16B), and introduced into the grinding chamber (15B). It is thrown in. This is the most powdered rebirth. Therefore,
The crushing (1) of the crushing chamber (15B) beats back the most powder and crushes it, which is introduced into the outlet (19B) and the pipe (20), sent to the shifter (21B), and sifted. The second powder is taken out from the shifter (21B).

Furthermore, the return of the second powder was introduced into the pipe (22), sent to the stamp mill, introduced into the charging port (16C), and the grinding chamber (15
It is thrown into C). Then, the crush (1) in the crushing chamber (15C) scrapes the crushed second powder and crushes it.
C) and the pipe (20), sent to the shifter (21C), sieved, and the second powder is taken out from the shifter (21C). The return of the third powder is introduced into the pipe (22), put into the crushing chamber (15C), and crushed again.

In the case of this stamp mill, the partition (13) between the adjacent ridges (1) divides the thin (3) into multiple grinding chambers (15).
A), (15B), (15C) are formed, and when the raw material is rubbed by each tine (1), the raw material is guided by each partition plate (13), and the raw material is laterally moved in the thin (3). There is no problem of moving in the direction. In each of the crushing chambers (15A), (15B), (15C), the raw material forms a layer having a constant thickness and moves forward along each partition plate (13). Then, in each of the crushing chambers (15A), (15B), (15C), plate-like ridges (1) having a width (W) corresponding to the width fall on the thin (3). Therefore, the ingredients for buckwheat flour are
The raw material mashed in (1) flows and moves forward as it is. The conventional raw material particles do not cause the problem that some of them are rubbed many times and some of them are not rubbed, and the raw material particles can be sequentially rubbed and crushed. Therefore, when the first powder is taken out from the shifter (21A), the taken out powder is white enough.

Furthermore, in each of the crushing chambers (15A), (15B), and (15C), the original raw material, the first powder return and the second powder return can be ground at the same time. Moreover, each grinding chamber (15A), (15B), (1
5C) communicates with each of the outlets (19A), (19B), (19C) and is individually connected, and after crushing, each grade can be taken out individually. Therefore, unlike the conventional case, it is not necessary to alternately crush the original raw material, the return of the first powder and the return of the second powder, and the efficiency can be significantly increased.

In this embodiment, two partition plates (13) are used to
Although one crushing chamber (15A), (15B), and (15C) has been described, it is needless to say that a greater number of partition plates may form more crushing chambers.
