Description

Description: TECHNICAL FIELD The present invention relates to a vertical-axis type grain mill that feeds grains from the lower side of a grain mill, mills them, and discharges them from above.

[Conventional technology]

A conventional vertical axis type grain refiner will be described with reference to FIG. Reference numeral 37 is a vertical type friction cutting type grain refiner, and a spiral rotator 40 is provided at the bottom of a main shaft 39 rotatably provided in an upright standing porous wall bran removal whitening cylinder 38.
And the friction grain trochanters 42 provided with the stirring projections 41 on the upper part thereof. The grain is supplied to the spiral rotator 40 from the grain supply unit 45 provided on one side wall of the machine frame 44 through the grain supply trough 43, and
Departed to 46. In the grain refining chamber 46, the grain is subjected to a polishing action caused by the rotation of the frictional grain trochanter 42, and is refined. The refined grain is discharged from the discharge port 47 through the discharge trough 48 to the outside of the machine.

However, in the conventional vertical axis type grain refiner as described above,
Since a void is formed above the upper end surface of the grain trochanter,
Part of the grain may be deposited on the upper end surface of the trochanter of grain during the milling process. Therefore, there is a problem that the accumulated grains return to the milling room and are mixed with other varieties (for example, sticky rice is mixed with glutinous rice).

[Problems to be Solved by the Invention]

This invention solves the above problems, prevents the accumulation of grains on the upper end surface of the grain trochanter during polishing of grain, and prevents the mixing of grains of different varieties. An object is to provide a vertical type grain refiner.

[Means for Solving the Problems]

In order to achieve this object, the present invention has the following configuration.

A spiral trochanter and a grain trochanter are mounted on a main shaft that is rotatably installed in an upright standing porous wall bran-removing white barrel, and the main components are a porous wall bran-removing white barrel and a grain trochanter. The lower end of the grain chamber to the grain supply section,
The upper end is connected to each grain discharge part to form a vertical grain mill. Then, a lid is hung vertically toward the upper edge of the fine grain trochanter so as not to create a void in which grain accumulates on the upper end surface portion of the fine grain trochanter.

[Work]

The grain supplied to the spiral trochanter from the grain supply part of the vertical axis type grain refiner is sent by the spiral trochanter, and the grain is mainly composed of the porous wall debris polishing white tube and the grain trochanter. She is licked in the room. At this time, the grain does not enter the upper end surface of the fine grain trochanter due to the lid body hung vertically toward the upper edge of the fine grain trochanter.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings. First
The figure is a side sectional view of a vertical type grain refiner, and FIG. 2 is a partially enlarged side sectional view thereof.

Reference numeral 1 is a vertical shaft type friction milling machine, in which a spiral rotator 4 is provided at the bottom of a main shaft 3 rotatably provided inside a standing porous wall sucrose degreasing and polishing cylinder 2, and a stirring projection 36 is provided at the top. Each of the provided friction grain trochanters 5 is axially mounted. A grain supply unit 7 is provided at a lower portion of a grain refining chamber 6 which mainly includes a porous wall debranching whitening barrel 2 and a friction grain trochanter 5.
Then, the upper part is connected to the grain discharge part 8, respectively. Main motor 9
The motor pulley 10 and the pulley 11 of the main shaft 3 to the V belt.
Connect by 12.

The grain discharge unit 8 is provided with a resistance plate 14 connected to an automatic resistance adjusting device 13 that regulates the grains discharged from the grain discharge unit 8. The resistance plate 14 is connected to the tooth shaft 16 via the lever 15,
Reference numeral 16 is linked to a forward / reverse rotation electric motor 17. When the tooth shaft 16 is horizontally moved by the forward / reverse rotation electric motor 17, the lever 15 is rotated about the resistance plate shaft 18 and the resistance plate 14 is rotated far and near to the grain discharging unit 8. A drain gutter 19 is provided so as to be connected to the grain discharge part 8, and a discharge gutter 20 is connected to the flow gutter 19.

The feed hopper 21 is attached to the grain feeding device 22 having one end facing the grain feeding unit 7, and the pulley 25 attached to the conveyor shaft 24 around which the spiral body 23 is wound and the pulley 27 of the electric motor 26 are connected to the V belt 28. Connect by.

The main shaft 3 is hollow and has a large number of ventilation openings 29, and the upper end opening of the main shaft 3 is connected to a blower 30. Further, the friction grain trochanter 5 is made hollow and provided with a blowhole 31,
The bran removal chamber 32 provided around the porous wall bran removal white tube 2 is connected to a cyclone (not shown) or the like via a bran removal duct 33.

In FIG. 2, a ring body 34, which is in close contact with the upper end of the friction grain trochanter 5, is provided on the main shaft 3 while being axially attached thereto, while a lid body 35 into which the upper bearing portion of the main shaft 3 is fitted is slightly attached to the ring body 34. It hangs down through a pinch.

FIG. 3 shows a case where the friction grain trochanter 5 is extended upward in place of the ring body 34 and is faced in the lid body 35 with a slight gap.

Next, the operation of the above configuration will be described. The grain is sent to the grain supply device 22 via the supply hopper 21, and the main motor 9
And the electric motor 26 are respectively driven, the kernel 23
Is supplied to the spiral trochanter 4 by the spiral trochanter 4 and is then transported to the grain mill 6 by the spiral trochanter 4 and subjected to the polishing action generated by the rotation of the friction grain trochanter 5 to be refined. At that time, rubbing fine grain trochanter 5
Since the lid 34 is hung vertically toward the upper end peripheral edge of the fine grain trochanter 5 so as not to create a void in which the grain accumulates on the upper end face portion of the Never accumulated on. Therefore, it is possible to prevent the accumulated grains from returning to the grain refining chamber 6 and being mixed with other varieties (for example, sticky rice is mixed with glutinous rice). Then, the bran removing effect is performed by the bran removing air blown from the blower 30 through the ventilation port 29 and the jet port 31.
Dust such as bran generated by the polishing action in the grain refining chamber 6 is discharged to the bran removing chamber 32 from the through hole of the porous wall bran removing whitening tube 2 and is collected from the bran removing duct 33 such as a cyclone (not shown). Sent to the device.

The refined grain reaches the grain discharge part 8 and is prevented from flowing out by the resistance plate 14 of the automatic resistance adjusting device 13.
By changing the suppression of, the accuracy of swelling is adjusted. Then, the grain flows out against the resistance plate 14 and is discharged to the outside of the machine through the flow-down gutter 19 and the discharge gutter 20.

In addition, in the present embodiment, the present invention is applied to the vertical type friction cutting type grain refiner, but it may be applied to the vertical type grinding type grain refiner.

〔The invention's effect〕

According to the vertical type grain refiner in the present invention, the lid is provided with the fine grain trochanter toward the upper edge rim of the fine grain trochanter so as not to generate voids in which grain is accumulated on the upper end surface portion of the fine grain trochanter. Since it is set up vertically, grains do not accumulate on the upper end of the fine grain trochanter.
Therefore, it is possible to completely prevent the accumulated grains from returning to the sperm chamber and being mixed with other varieties (for example, sticky rice is mixed with glutinous rice).
