Description

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

This type of circulating grain milling machine continuously mills rice by passing through a milling chamber formed in a mortar-shaped container many times until it reaches a specified white color, so even if the milling part is worn out and efficiency decreases, Since there is no limit to the polishing time, it is convenient and easy to leave the rice until the desired white discoloration is achieved, and the purpose can finally be achieved. However, in this case, the rice grains continuously flow through the circulation process,
Due to the structural lack of ventilation in the milling room, sticky bran powder adhering to the rice grains could not be removed, and dirty, unclean white rice with no shelf life was always used.

Therefore, the present inventor has developed a device that activates the bran removal action by providing a ventilation window in the peripheral wall of the mortar-shaped container near the milling chamber and supplying the wind flowing through the ventilation window intensively to the milling chamber. This was developed and provided as shown in the example diagram, but in this case, in order to increase the speed of the air flowing in through the ventilation window and perform a high rate of bran removal, it is necessary to It is necessary to seal the supply opening of the container.

In view of the above points, the present invention provides a grain milling machine in which a milling chamber is formed between a milling trochanter shafted inside a mortar-shaped container and a porous wall for removing bran provided at the bottom of the container. A ventilation window is provided on the peripheral wall of the container, and a removable lid is provided on the supply port of the container, so that the lid is closed to seal the mortar-shaped container, and the air flowing in through the ventilation window is is circulated through the milling room and removed from the porous walls for rice bran removal, thereby increasing the wind speed in the milling room to perform a highly efficient bran removal and abrasive action, and to produce high-quality polished rice without adhesion of rice bran. The aim is to develop and provide high-performance equipment to ensure this.

The present invention will be explained with reference to embodiment figures. Porous walls 2 and 3 for removing bran are provided at the lower periphery and bottom of the mortar-shaped container 1, the outer periphery of which is surrounded by an exhaust mantle 4, and the bran is guided centripetally to the center by a channel 5 to remove the bran. The bran removal passage 5 is connected to the exhaust chamber 10 in which the impeller 9 is mounted on the lower part of the vertical shaft 8 on which the trochanter 6 is mounted, and 7 is connected to the upper part of the polished trochanter 6 mounted on the vertical shaft 8. A shaft-mounted transport trochanter, 11 the cylindrical wall of the porous wall 3, 12 the refined trochanter 6 and the porous! 13 is an exhaust port of the ventilation chamber, and 14 is a ventilation provided on the peripheral wall 15 of the container 1 to supply air to the rice polishing chamber 12 through the rice grain layer in the mortar-shaped container 1. A window, 16 is a lid removably provided on the supply port 17 of the mortar-shaped container 1, 18 is a switch mechanism provided on the supply port 17 of the container, and 19 is an MID device 12 of the switch mechanism and electric motor.
0, A is the bran collector, and B is the electric motor for driving the grain milling machine.

Therefore, when rice grains (brown rice) are put into the mortar-shaped container 1, the lid 16 is closed, and the device is started, the container
The rice grains inside are sent to the lower milling chamber 12 by the transport trochanter 7, polished while being stirred by the milling trochanter 6, and taken out in the circumference. The bran powder generated by this whitening action is absorbed by the suction force generated by the rotation of the impeller 9 in the ventilation chamber 10, together with fresh air flowing in through the ventilation window 14 provided in the peripheral wall 15 of the mortar-shaped container 1 near the polishing chamber 12. Porous wall for removing bran 2
．． 3, and the sugar-containing air passes through the bran removal channel 5 and the exhaust chamber 10 and is discharged from the exhaust port 13 to the bran collector A. Since the supply port 17 of the container 1 is sealed, the wind flowing in through the ventilation window 14 is
The wind speed is increased to perform high-efficiency bran removal and to promote the abrasive action of the rice grains, and the polished rice is circulated through multiple mouths in the mortar-shaped container 1 to produce glossy polished rice with a predetermined polishing degree. It is milled and taken out of the machine.

Claim (2) provides that the lid body 16 is
The opening or opening operation of the lid opens the switch mechanism 17 to start or stop the operation of the drive electric motor B of the grain milling machine. In addition to increasing the speed of the air flowing in through the ventilation window, the noise inside the container during milling can be suppressed to improve the working environment. When the lid is opened, the operation of the grain milling machine stops and the rice grains are milled. This has the effect of allowing inspections to be carried out safely and easily.

The switch mechanism 17 may be provided on the lid side, and in addition to the illustrated microswitch 21, a proximity switch, a reflective photosensor, or the like may be arbitrarily selected and used.

Also, the switch 1111117 causes the rice bran collector H to
There are cases where A's electric $122 operation is IllJwJ.

FIG. 2 shows an inverted state in which a magnet 23 for operating a proximity switch is attached to the lid 16.

In this way, the ventilation device of the W4 grain machine of the present invention closes the lid body to seal the mortar-shaped container, and at the same time, the wind flowing from the ventilation window is circulated into the milling room and removed from the porous wall for bran removal. So,
The wind flowing in through the ventilation window increases the wind speed and is intensively supplied to the milling room, so the strong wind can perform a high rate of bran removal and promote the abrasive action of rice grains. It is sealed and can prevent noise and flying dust during milling, and also has the effect that milling can always be done to produce high quality glossy polished rice with no adhesion of bran without causing any danger during the operation.
