Description

Description: TECHNICAL FIELD The present invention relates to a hard-axis rice milling machine that supplies brown rice from the lower part of a whitening chamber to whiten it and discharges it from the upper part.

[Conventional technology]

In the conventional hard-axis rice milling machine, when the degree of whitening is increased during polishing, the flow resistance of the rice grain is increased by a whiteness adjusting device installed above the outlet of the whitening chamber. In order to increase the resistance, the suppression of the rice grains from the brewing chamber is increased, which lowers the ability of the spiral trousers to pump the rice grains, which in turn lowers the milling ability.

[Problems to be solved by the invention]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide a hard axis type rice milling machine capable of preventing the drop of the rice grain feeding ability due to the spiral rotator even when the accuracy of the grinding is increased.

[Means for solving problems]

Part of the cylinder standing upright in the machine frame is used as a porous wall degreasing white cylinder,
A spiral trochanter and a white trochanter are axially inserted into a rigid shaft rotatably provided in the cylinder, and the lower part of the whitening chamber whose main part is a porous wall sucrose whitening cylinder and a white trochanter is a brown rice supply part Contact the top of the white rice discharge section. A hollow upper feeding screw conveyor shaft is concentrically connected to the upper part of the white trochanter, and a connecting rod is slidably fitted to the screw conveyor shaft so that the lower part of the connecting rod is the white rice discharging part. The upper part of the resistance plate provided is connected to a compression degree adjusting device for adjusting the pressure of the resistance plate to form a hard axis type rice milling machine. Then, the technical means of providing a protrusion on the inner peripheral surface of the cylindrical body surrounding the spiral rotator was taken.

[Work]

The rice grain supplied to the spiral trochanter from the brown rice supply section of the hard axis type rice mill is pumped by the spiral trochanter against the resistance of the resistance plate, and is mainly fed to the perforated wall degreasing whitening barrel and whitening trochanter It is refined in the whitening room. Polished white rice is discharged from the white rice discharging part, and further, it is fed up by a screw conveyor and discharged to the outside of the machine, but due to the protrusion provided on the cylinder surrounding the spiral rotator, The frictional force with the rice grain is increased, and the pressure of the rice grain from above is dispersed and reduced to prevent the lowering of the lifting ability of the spiral trochanter.

Next, the operation of the above configuration will be described. When the motor 14 is driven, the brown rice in the brown rice tank 10 flows down the bottom plate 11 and is sent from the supply gutter 12 to the spiral rotator 4 through the supply port 8. The brown rice is pumped to the whitening chamber 7 by the spiral trochanter 4 and subjected to the polishing action generated by the rotation of the frictional whitening trochanter 6 to be refined. Then, the blower 17 sucks from the intake port 22 and blows out from the blowout port 23 to perform the sugar removal action.

The polished rice reaches the white rice discharge port 9 and flows out against the resistance plate 32 while the resistance plate 32 suppresses the outflow. Then, the white rice is fed upward in the upper conveying device 25 by the spiral body 26 of the conveyor shaft 27, and the white rice reaching the upper end is promoted to be discharged by the scraping blade 40, and is discharged from the discharge trough 42 via the refined product discharge port 41. It is discharged to the outside of the machine.

Immediately before the start of polishing, the incompletely polished rice is discharged from the discharge gutter 42. Therefore, the forward / reverse rotation motor 43 is operated to reverse the discharge gutter 42 to the position indicated by the chain line to circulate the unpolished rice. In other words, the unpolished rice drops from the refined product discharge port 41 to the rice collecting trough 44, is sent from the supply gutter 12 to the brown rice supply port 8 via the return gutter 45, and is re-polished. Then, after confirming that the proper lapping accuracy has been reached after a certain period of time through the window 46 and the forward / reverse rotation motor 43 is operated to reverse the discharge gutter 42 to the position of the solid line, the white rice is discharged into the discharge gutter
It is discharged from 42 to the outside of the aircraft.

When the handle 39 is pushed down, the connecting rod 30 is pushed down via the bearing 36, and accordingly, the resistance plate 32 is pushed down via the tubular body 51. As a result, the pressure in the polishing chamber 7 is increased and the grinding accuracy is improved, and the polished rice having an appropriate grinding accuracy is fed up by the spiral body 50 of the resistance device 49 and then further moved up by the spiral body 26 of the screw conveyor shaft 27. Will be sent.
At this time, the spiral body 50 wound around the cylindrical body 51 of the resistance device 49 promotes the upward feeding action and prevents the staying.

It should be noted that when the compression degree adjusting device 35 is operated as described above to increase the accuracy of grinding, the pressure in the polishing chamber 7 rises, and the pressure on the spiral trochanter 4 portion thereunder also rises. However, the pressure is dispersed and reduced by the protrusions 53, and the frictional force between the cylindrical body and the rice grains is increased by the protrusions, which lowers the ability of the spiral rotator 4 to feed the rice grains.
