Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flour milling apparatus, and more particularly, it reciprocates a sieve and sieves the pulverized powder while applying an impact force to the sieve. Even if you use a fine-mesh sieve without clogging for a long period of time, you can sieve extremely fine particle powder, especially in wheat flour,
The present invention relates to an epoch-making household flour milling device which is commercially available from a flour milling company and which makes it possible to obtain highly smooth wheat flour having a grain size of 100 mesh or less and having a very smooth texture.

[0002]

2. Description of the Related Art Conventionally, wheat growers have used a so-called ground flour, which is made by crushing home-grown wheat into powder using a home-use flour mill and then sieving to separate only small-sized flour into wheat flour. I was making noodles and so on. Foods using the ground flour have a unique flavor that is difficult to obtain from commercially available flour, and are appreciated by many people.On the other hand, compared to commercially available flour, the color is reddish black and the texture is unpleasant, and the texture is not good. It had the drawback of being bad.

The reason why the color is red and black and the texture on the tongue is bad is
Part of a very small bran that has passed through an 80-mesh sieve mixed with milled wheat flour, which is the finest sieve normally used as a household sieve.
The size is difficult to screen with a mesh screen.

The reason why sieving is not carried out with a sieve having a mesh finer than 80 mesh is that if a sieve with a mesh finer than this is used, sticky wheat flour will adhere immediately to the eyes of the sieve and the sieve will be removed each time. This is because sieving work is done while cleaning, and it is difficult to use in practice.Therefore, although there is a strong demand for home-made flour with a smooth texture that has a particle size similar to that of commercially available flour, The current situation is that they can never be manufactured.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned drawbacks of the prior art. The object of the present invention is to perform the operation of sieving powders produced by a mill. It is to be able to remove red and black wheat bran by sieving while applying impact force to sieving so that sieving can be performed using a fine mesh sieve of 100 mesh or more, which is difficult in normal sieving work, In addition, this makes it possible to produce flour having a white color, a very smooth texture, and a fine grain size, which can be produced by a general household such as a farmer.

Another object is to reciprocate a sieve to separate powder into powder having a predetermined particle size or less, and to align a shaft center in the reciprocating direction of the sieve with a guide rod fixed to the sieve. By slidably fitting a weight with a gap in the direction, the weight collides with the sieve at both dead points of the reciprocating motion of the sieve, and an impact force is applied to the sieve to simply reciprocate the sieve. It is to enable the powder to be sieved by using a fine mesh sieve of 100 mesh or more with a simple device that only moves, and to provide it as an inexpensive milling device to general households such as farmers. .

By rotating in the direction A, the rotation is transmitted to the pulley 6 via the belt 10, and the mill (not shown) of the flour mill 2 is rotated in the direction of arrow B to grind the wheat grains, and further the rotation is performed. Pulley 3 via belt 32
0 is transmitted to rotate the rotary plate 28 in the direction of arrow C.

The rotation of the rotary plate 28 is converted into a parallel motion through the eccentric pin 29, the lever 26 and the shaft 25 and transmitted to the moving base 23, which moves on the rail 22 along the arrow D.
Alternatively, it is adapted to reciprocate in the E direction.

The impact mechanism 14 is for applying an impact force to the wooden screen 13, for example, and in FIG. 5 to FIG. 7, the metal guide bar 33 is provided with a metal stay 33a which is strong against repeated impact. The guide bar 33 is fixed to the rectangular frame 18 so as to face the reciprocating direction of the screen 13 (directions of arrows D and E).
A pipe-shaped weight 34 made of, for example, iron and having a length slightly shorter than the length of the guide rod 33 is slidably fitted therein with a gap in the axial direction.

When the sieve 13 reciprocates in the direction of arrow D or E, the weight 34 moves in the direction of arrow F or G due to inertial force at both dead points where the movement of the sieve 13 stops, and the weight 34 collides with the stay 33a. An impact force is applied to 13.

The present invention is configured as described above,
The operation will be described below. 1 and 8 to 1

It is converted and transmitted to the movable table 23, and the movable table 23 is reciprocated on the rail 22 in the arrow D or E direction.

The wheat flour 4 discharged from the outlet 12 of the flour mill 2 in which the husk and the fruit are mixed together is moved by the arrow D along with the moving table 23.
Alternatively, it falls on the shielding plate 19 of the sieve 13 which reciprocates in the E direction, is distributed evenly in the net 16 without being solidified in one place, and the flour 13 having a fine grain size of 100 mesh or less is reciprocated by the sieve 13 which reciprocates. Only the particles pass through the mesh 16 and fall, are sieved, and are stored in the storage chamber 15b.

The sieving work by the screen 13 will be described in detail below.
In FIG. 8, when the rotary plate 28 rotates in the direction of arrow C and the eccentric pin 29 reaches the right end, the reciprocating motion of the movable table 23, that is, the screen 13, changes from rightward movement to leftward movement in the figure. To stop at right dead center.

At this time, the pipe-shaped weight 34 slidably fitted to the guide rod 33 is further moved in the direction of arrow G by the amount of the axial gap due to the inertial force to move to the metal stay 3.

Flour that adheres to the eyes and tries to clog the mesh 4
The fine wheat flour 4 is dropped, and the rough wheat flour 4 and the bran are lifted to eliminate clogging and restore the sieving function.

In FIG. 9, similarly, when the rotary plate 28 rotates in the direction of arrow C and the eccentric pin 29 reaches the left end, the reciprocating motion of the sieve 13 similarly moves from left to right in the drawing. However, due to inertial force, the pipe-shaped weight 34 further moves in the arrow F direction by the amount of the axial gap and collides with the metal stay 33a, and the weight of the weight 34 is reduced. The kinetic energy, which is the product of the square of the velocity, acts as an impact force on the sieve 13 to cause the fine flour 4 to drop the flour 4 adhering to the mesh of the mesh 16 and clogging the mesh of the mesh, and rough wheat flour. 4 and bran are lifted to eliminate clogging and restore the sieving function.

As described above, at the both ends of the reciprocating motion of the screen 13, the screen work is performed while the weight 34 exerts an impact force on the screen 13, so that the screen 13 does not become clogged and is stable and fine for a long period of time. 4 can be sieved, and the bran 20 remaining after being sieved is discharged from a discharge port 21.

In the above-mentioned embodiments, the grain is described as wheat flour that is milled as wheat grain, but the grain is not limited to wheat grain, and grains such as rice grain and buckwheat noodles may be used to obtain fresh flour. Of course, it is also possible to mill buckwheat flour or the like.
