Description

[Detailed description of the invention] The present invention relates to a vertical grain milling device.

An object of the present invention is to make it possible to perform load milling in a vertical grain milling apparatus, which was previously considered impossible, by automatically controlling the milling room load.

Another object of the present invention is to make it possible to efficiently mill rice by making the polishing cylinder have a special structure.

Compared to horizontal grain milling equipment, vertical grain milling equipment has the advantage of being able to mill grain in its original form and has a significantly lower incidence of broken rice. Because it is a grain milling machine, it has a defect that its milling capacity is very low (about the level of a horizontal grain mill).0 For example, the machine shown in Fig. and roll C are attached, and this is surrounded by a milling barrel and a grain feeding barrel D', brown rice is supplied from the supply port E, and is discharged from the discharge port F, and a resistance lid G is attached to the discharge port F to mill the rice. A load is applied to the rice grains in the room, and the horizontal shaft A is rotated to polish the grains.The powerful feeding action of the grain feeding spiral B is stopped by the resistor lid G, and pressure is applied to polish the rice. It has the advantage of being able to obtain
On the other hand, it has the disadvantage that a lot of broken rice is produced due to forced milling. In addition, in the case of horizontal grain milling equipment, rice grains are distributed thickly in the lower layer of the milling chamber due to their own weight, and are hardly distributed in the upper layer of the milling chamber, resulting in uneven rice grains.

The example shown in Figure 2 is a vertical grain milling device that is often used in sake brewing factories. The shaft H does not protrude above the grinding trochanter (2), but only downward, and the pulley is fixed at a position below the grinding trochanter (I), and has a downward drive structure. In this vertical grain milling device, when rice grains a are supplied from a supply port J formed at the upper center of the milling chamber M, the rice grains a are uniformly supplied into the milling chamber M and then rotate horizontally. The grain is ground while being stirred horizontally by a grinding trochanter (grinding wheel made of diamond sand), and is discharged by centrifugal force through a discharge port formed at the bottom. Because it is opened on the side of the milling room M, rather than at the bottom of the center, the rice grains that have accumulated in the area marked by the arrow on the opposite side of the discharge port are not easily discharged. Of course, since the grinding trochanter rotates at a high circumferential speed of 2,000 feet per minute, the rice grains in the area indicated by the arrow above are also horizontally agitated by the grinding trochanter and discharged through the discharge port by centrifugal force. However, if the resistance of the resistor cover G attached to the discharge port K is made even slightly too strong, it will suddenly become clogged, causing an accident in which the grinding rotor I will not rotate at full heat. That is, the resistor cover G is only a resistor device in appearance, and is used with almost no resistance applied, so it cannot be polished efficiently.

The vertical grain milling device shown in Figure 3 is an improved version of the defect in the grain milling device shown in Figure 2, since the outlet K is shifted to one side, which causes grain to accumulate outside Ls on the opposite side. It is.

The vertical shaft H does not protrude downward from the grinding machine 1, but upwardly, and a pulley N is attached thereto, and the structure is driven upwards, so that the discharge port is located directly below the center of the milling chamber M. It is now possible to open the rice bowl, and there is no accumulation of rice grains. However, in the case of Fig. 3, unless the structure is such that the rice grains are supplied into the milling chamber M through the pulley N, it is not possible to uniformly supply the rice grains to each part of the milling chamber M. In such a case, since the pulley N is rotating at a fairly high speed, the rice grains may bounce back and a smooth inflow action cannot be expected.

Unavoidably, the clay wall of the milling room M is opened at the part indicated by arrow A, which is shifted to one side from the center, and raw materials are supplied from there. Therefore, it cannot be avoided that it is unreasonable.

Therefore, in the present invention, the vertical shaft H is returned to protrude downward as shown in FIG. The rice is also discharged from directly below the center of the milling chamber, and the structure of the milling chamber is designed to allow efficient milling.

The present invention a. Attach the white trochanter to the rotating shaft of the vertical shaft.

b. A whitening chamber is formed by surrounding the whitening trochanter with a vertical whitening cylinder.

The C6 polishing tube is suspended within the frame so that it can move up and down depending on the load.

d. At the lower end of the whitening chamber, a discharge passage is formed that gets caught when the whitening cylinder moves upward and widens when the whitening cylinder moves downward.

e. The polishing tube is formed by alternately combining three grinding posts and three bran removal wire meshes.

f. The inner surface of the grinding column is exposed inside the milling chamber.

g. The inner surface is formed in a tangential direction of a concentric circle of the rotation axis.

h. The inner surface is formed into a rough surface.

The gist of the bran-removed wire mesh is a combination of the requirements of 〇, which is formed into a dogleg shape on a plane.

The upper end of the shaft body 62 is fitted to form a flexible joint. The lower end of the spring @ is fixed to the lower end of the rod ■,
Fix the upper end of the spring (■) to the spring receiving protrusion on of the spring receiving ring (8).0 As is clear from Fig. 4, the direction in which the manual operation lever a2 is rotated horizontally to extend the spring When the spring bearing ring (8) is rotated, the elasticity of the spring becomes strong and the degree of polishing can be adjusted.

The upper end of the polishing m (c) is coupled to the lower end of the vertically sliding tube aS. The specific structure of the polishing tube (c) is shown in FIG. 14 and subsequent figures. The polishing tube (C) is mainly formed by three bran removal wire meshes (X) bent into a dogleg shape and three grinding supports (B) installed between the bran removal wire meshes (X). ing. The bran removal wire mesh (to) is usually called a wire mesh, but it is actually a perforated plate with perforated holes for bran removal formed on the entire surface. , its inner surface is formed into a rough ground surface. The left and right sides of the bran removal wire mesh are each bent outward to form a clamping piece. A grinding support is clamped between the clamping piece (g) and the clamping piece ω of the next wire mesh (to), and is tightened by the bolt eiη and the nut hole.

The grinding post is shaped like a square bar and is made of metal such as iron. The inner surface of the support (b) is formed to be a tangent to a circle centered on the rotation axis (c), and the inner surface 61 is provided with a vertical wave. Genami ■ can be substituted for any rough surface. fI9 is a hole through which the bolt 6η passes. Inside the polishing tube (c), there is a polishing trochanter (goods) which is a friction trochanter.
is installed. The grain feeding spiral all and the milling trochanter @
is fixed to the upper end of the vertical shaft (c), and a vertical protrusion (to) is formed on the outer periphery of the trochanter (c). The protrusions (C) may be provided to be inclined in a direction that causes the rice grains in the milling chamber Kg to float upward, and the milling trochanter Q4 may also be a blower trochanter. The connection is the blowhole, the 0-white trochanter Q
4 When using a Q blower trochanter, the shaft (C) is a hollow pipe that also serves as a blower pipe.The white trochanter in the 0 embodiment is formed to have the same diameter from beginning to end, but when it extends downward Accordingly, the upper end of a part of the teeper (to), which becomes smaller in diameter as it goes downward, is connected to the lower end of the zero-refined trochanter Q41, which may be formed in an inverted conical shape with a smaller diameter. The upper end of the small diameter portion (2) is joined to the lower end of the teeper portion (end). The small diameter part (end) has a constant height in the vertical direction, and the upper end of the teeper guide surface (2) whose diameter gradually increases as it reaches the bottom is joined to its lower end. The lower end of the polishing tube is connected to the polishing transfer fc! 4, and the upper end of the resistor 01) is attached to the lower end thereof. The horizontal collar at the upper end of the resistor 01) is brought into contact with the lower surface of the grinding column, and a set screw is inserted from the lower side to fix the resistor. The resistor G11 is formed into an annular body, and its upper end is formed to be equal to the inner diameter of the lower end of the polishing tube (end), but until it reaches the middle part in the vertical direction, it has a trap that extends downward. Therefore, an enlarged part (

A part of (b) is cut out and opened to open the discharge port (to)? A discharge gutter an is attached to the outside of the discharge port. The space a1 in the upper frame (2) also serves as a dropping chamber in which the bran ejected from the polishing tube (to), which is a bran removal tube, falls, and the teaper guiding surface (
A bran suction blade (to) is provided below the bran suction blade (to).

Next, we will discuss the effect.

When raw brown rice is put into the supply hopper (6), the brown rice flows down from the lower end (141) of the hopper (6) and is subjected to the downward feeding action of the grain feeding spiral II9, and the outer surface of the milling trochanter (end) and the milling It flows into the polishing chamber !12 formed between the inner surface of the tube (2). Immediately after the polishing starts, the upper and lower sliding tubes a, the polishing tube, and the resistor C111 are connected to the spring ■
It is lifted up to the maximum due to the elasticity of the resistor Cl1
1, as shown in FIG. 11, the discharge passage X formed by the teeper resistance surface 02 and the tip of the teeper is made as narrow as possible, so the flow of rice grains is poor and they gradually accumulate. As a result, the pressure gradually increases. When the milling trochanter (2) rotates counterclockwise in the milling chamber 42 as shown in FIG.
When passing through the corrugated part of the inner surface 69 of the grinding support (b) from the mouth point to the convex point, it is ground as if it were being cut with a file. As they pass through point 8 and head towards point 2, they are mixed by the whitening chamber (42) which gradually expands, and when reaching point 2, the whitening chamber 32 gradually narrows, so that the particles are pressed against each other. The rice grains are swollen, subjected to strong grain-by-grain friction polishing, and the above action is repeated again.As this polishing action continues, the amount of rice grains clogging inside the milling chamber 143 gradually increases, so that the broken rice size...J. As a result, the pressure inside the whitening room becomes increasingly high.

In this case, a counterclockwise force is applied to the polishing tube (C) as shown in Figure 4, causing it to turn counterclockwise against the elasticity of the spring (C), but the rod ■ is installed at an angle. As a result, the shaft part α1 at the lower end of the rod ■ is as shown by the arrow in Fig. 4.
The shaft portion 12 [+] moves diagonally downward, and therefore,
The polishing cylinder (c) changes from the state shown in FIG. 12 to the state shown in FIG. 13, and the discharge passage X is enlarged.

The present invention has the above-described structure and operation, and particularly, a, a white trochanter on the axis of rotation of the vertical axis c! Install 41.

b. The whitening chamber 11Z is formed by surrounding the whitening trochanter e141 with a vertical whitening cylinder (c).

The C0 polishing tube (c) is suspended within the frame (2) so that it can move up and down depending on the load.

d. A discharge passage
form.

e. The polishing tube (c) is formed by alternately combining three grinding columns 64 and three bran removal wire mesh trowels. .

g. The inner surface is also formed in the tangential direction of the concentric circle of the rotation axis (c).

h. The inner surface 61 is formed into a rough surface, and the bran removal wire mesh (to) is formed into a dogleg shape on a plane.

This is because it is a vertical grain milling device that combines the following requirements (1)
Milling can be done with the pressure inside the milling room (4a) higher than that of conventional vertical grain milling equipment, so even though it is vertical, it can increase efficiency close to that of a horizontal type.Therefore, it has the effect of increasing the yield ( 2) When the pressure in the polishing chamber (4B) increases, the polishing tube (c) automatically rotates and moves downward to automatically enlarge the discharge passage X, which eliminates the risk of broken rice. None.

(3) The polishing cylinder (c) is formed by three grinding supports (goods) and three bran removal wire meshes Q, and the inner surface (to) of the above-mentioned support posts 6
is the tangential direction of the concentric circle of the rotation axis (c), and the inner surface -
Since the bran removal wire mesh Q has a dogleg-shaped plane, when the rice grains pass through the inner surface 61, they are ground, and in the bran removal wire mesh 53, they are subjected to agitation and grain-by-grain friction, and this process is repeated. Because it is pumped by doing so, it is pumped efficiently.

(4) The grinding support serves as both a support and a file.

This effect is achieved.
