Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for supplying grain from one end of a grain milling room, converting it into M grains, and discharging it from the other end. Concerning a scraping type vertical grain milling machine.

[Conventional technology]

A conventional friction type vertical shaft grain milling machine will be explained with reference to FIGS. 5 and 6. FIG. 5 is a plan sectional view showing a conventional example, and FIG. 6 is a partially enlarged view thereof.

I which has a stirring protrusion 40 and an air blowing hole 41 in a porous-walled rice bran removal cylinder 39! A J grinding grain trochanter 42 is provided, a grain milling chamber 43 is provided between the porous wall bran removal polishing cylinder 39 and the friction grain polishing trochanter 42, and a ventilation port 45 is provided in the vertical shaft 44. The grains in the grain milling chamber 43 are milled by the milling action generated by the rotation of the friction milling trochanter 42 . During milling, some of the grains may enter through the blast groove 41, fall through the friction milling trochanter 42, and accumulate at the bottom. Therefore, due to the accumulated grains, f'? ! The grinding grain trochanter 42 causes eccentric movement, resulting in poor milling of the grains, or the accumulated grains return to the grain milling room 43 and contaminate other varieties (for example, sticky rice is mixed with glutinous rice). There was a problem with the problem of contamination.

(Problems to be Solved by the Invention) This invention solves the above-mentioned problems, and eliminates problems such as poor milling caused by grains penetrating and accumulating in the friction milling trochanter during grain milling, and varieties. An object of the present invention is to provide a friction type vertical shaft type grain milling machine that can prevent mixing of different grains.

[Means for solving problems]

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

A friction milling trochanter having a spiral rotor, stirring protrusions, and blowholes is inserted into a vertical shaft rotatably provided in an upright porous wall rice bran polishing cylinder, and the porous wall rice bran polishing cylinder and I ! j! A vertical grain milling machine is formed by connecting one end of the grain milling chamber, the main part of which is a grain grinding trochanter, to a grain supply section and the other end to a grain discharge section. The blast holes of the friction grain polishing trochanter are formed to prevent grains from entering the friction grain polishing trochanter.

[For production]

I! The grains supplied to the spiral trochanter from the grain supply section of the scraping type vertical shaft type grain milling machine are sent by the spiral trochanter and are passed through the perforated wall bran removal milling cylinder and the friction grain milling trochanter as main parts. The grain is milled in the grain milling room. The milled grains are discharged from the grain discharge section and sent to the next process. The grains are prevented from entering the I'1fl grain trochanter by the blowhole of the friction grain trochanter.

Next, the operation of the above configuration will be explained. Grain is fed to feed gutter 2
7 to the grain feeding device 18 of the friction type vertical grain milling machine 1. When the main electric motor 10 that drives the vertical shaft 3 and the electric motor 16 that drives the grain feeding device 18 are started, grains are fed from the grain feeding section 7 to the spiral rotor 4 by the spiral body 22 . The grains are transported to the grain milling chamber 6 by the spiral rotor 4, and are milled in the grain milling chamber 6 by the milling action generated by the rotation of the friction grain milling rotor 5, and the milled grains are sent to the grain discharge section. Reach 8. The resistance cover 24 of the pounding precision adjusting device 23 suppresses outflow to the discharge gutter 25, and by changing the suppression of the resistance cover 24, the pounding precision can be adjusted.

The grains are then sent from the discharge gutter 25 to the next stage via a scrape conveyor 26. Dust such as bran generated by the milling action in the grain milling room 6 is discharged from the holes in the porous wall rice bran removal rr II 2 and sent to the rice bran collecting room 30, where it is sucked and pressure-fed by the exhaust fan 31 and transferred to the rice bran discharge pipe 32. It is then sent to a bran collector such as a cyclone (not shown).

Fig. 2 shows the function of the grain intrusion prevention wall 36.

This will be explained with reference to FIG. The grains in the grain milling chamber 6 are prevented from entering the friction grain trochanter 5 by the grain intrusion prevention wall 36,
Therefore, poor milling and mixing of grains of different varieties due to eccentric movement caused by grains falling and accumulating on the friction milling trochanter 5 can be prevented. In addition, the bran removing air is blown into the grain milling room 6 through the ventilation holes 35 of the vertical shaft 3 and through the holes in the wire gauze 37 due to the suction force of the exhaust fan 31. The interior of the trochanter 5 is brought into a static pressure state, and the bran removing air is blown out from the wire gauze 37 evenly above and below.

Intrusion of grains into the ll'X milling trochanter is prevented, and it is possible to completely prevent poor milling and mixing of grains of different varieties due to eccentric movement caused by falling and accumulating grains.

In addition, the grain intrusion prevention wall creates a static pressure inside the friction milling trochanter, and the bran removal air can be ejected evenly from the upper and lower sides through the holes in the grain intrusion prevention wall, thereby preventing uneven bran removal.
