A screw 37 including a screw blade 37a and a screw shaft 37b is built in the fried grain cylinder 36.

At the upper end of the fried grain cylinder 36, a white rice discharge port 3
8 is provided, and a supply port 43 is provided at the lower end thereof.
The lower end is fitted to the fitting portion 41 of the holding cylinder 40. A white rice hopper 42 is provided at the supply port 43.

The fitting portion 41 is connected to the disk storage chamber 45 via the inverted truncated cone portion 44. Therefore, the disc storage chamber 45 is formed to have a smaller diameter than the fried grain cylinder 36. A fall prevention disc 46 is rotatably disposed in the disc storage chamber 45, and the disc 46 is fixed to the screw shaft 37b. The diameter D1 of the fall prevention disc 46 is smaller than the diameter D2 of the disc storage chamber 45, and both 45,

Next, the operation of this embodiment will be described. First, the case of standard operation will be described. Front door 3
5 Press the main body case 1 which is closed, caster 5
While rotating 0, move to a brown rice storage area (not shown).

After inserting the plug of the rice polishing apparatus into a 100V outlet, the upper lid handle 51 of the main body case 1 is opened to open the upper lid 52, and the brown rice G is put into the hopper 4. At this time, since the height of the hopper 4 is the waist height of an adult, for example, the height from the floor F is about 740 mm, brown rice can be easily introduced. A white rice container (bag) 55 is set below the white rice discharge port 38 of the fried grain cylinder 36, and a bran container (bag) 56 is set below the cyclone 3, and the opening edge thereof is hooked on the locking claw 32.

Since the position of the white rice discharge port 38 corresponds to the upper part of the brown rice hopper 4, the white rice discharge port 38 and the floor surface F.
A wide space can be secured between Therefore, it is possible to install a tall and large capacity rice bowl 55,
It is not necessary to change the white rice container 55 many times during the rice polishing operation.

When the start button 57a of the operation control section 57 provided on the upper surface of the front door 35 is pressed, the power lamp is turned on. When the start button 57a is pressed again, the main motor 9 and the grain-raising motor 47 are started and the operation is started.

When the shutter S is opened and the brown rice G in the hopper 4 is dropped into the whitening chamber 6, the brown rice G is pressure-fed into the whitening chamber 6 by the grain transfer roll 7 and receives the rotational force of the whitening roll 8. While being refined. At this time, the light from the light emitting portion L1 of the optical sensor L is blocked by the brown rice G and does not enter the light receiving portion L2.

The bran N falls from the bran net around the polishing chamber 6 into the bran recovery hopper 58. The bran N is sucked by the suction blower 70, conveyed to the cyclone 3, separated from the air A, and then dropped into the bran container 56. The air A is the air escape hole 3
It is released from 0A into the atmosphere, but since this air A is clean, there is no danger of polluting the room.

The white rice R in the polishing chamber 6 is an automatic resistance device 12
While falling under the resistance of the above, the water drops into the drop gutter 26 and flows down into the white rice hopper 42 while being regulated by the guide plate 27.

The white rice R that has entered the white rice hopper 42 flows down along the fitting portion 41 and the inverted frustoconical portion 44 through the supply port 43 and onto the fall prevention disc 46 of the disc storage chamber 45. To fall. At this time, the gap w between the fall prevention disc 46 and the disc storage chamber 45 is formed smaller than the white rice R, so that the white rice R will not flow down any more.

The white rice R dropped on the disk 46 is pushed up by the rotating screw blades 37a, rises in the fried grain cylinder 36, is discharged from the white rice discharge port 38, and is dropped in the white rice container 55.

At this time, the diameter D2 of the disk storage chamber 45 is formed smaller than the diameter of the fitting portion 41, and the fall prevention disk 46 in the disk storage chamber 45 is near the inverted truncated cone portion 44. The white rice R dropped on the disk 46 because it is installed in
Is immediately raised by the rotating screw blade 37a. Therefore, the white rice R does not remain below the screw 37. Since the inverted truncated cone portion 44 is tapered, the white rice R drops smoothly.

The brown rice hopper 4 is emptied and the brown rice G is connected to the gutter 5.
When it disappears, the light of the light emitting portion L1 of the photosensor L enters the light receiving portion L2. Then, the light receiving section L2 is operated by the operation control section 57.
To the main motor 9 and the fried motor 47 are turned off. Therefore, rice polishing machine 2
The grain fried machine 34 is automatically stopped after the rice polishing work is completed, and is turned off after a predetermined time, for example, 1 minute.
Since a delay circuit is provided in the switch of the grain-lifting motor 47, after the operation of the main motor 9 is stopped, the operation is continued for a predetermined time and then stopped. Therefore, the fried cylinder 3
The white rice in 6 can be discharged.

The white rice container 55 and the bran container 56 are carried to predetermined positions for processing, and the main body case 1 is moved to a storage location.

Next, the case of occurrence will be described. That is, the ammeter AM of the alarm device T detects the value of the current flowing through the main motor 9 and outputs it to the comparator CM. When the white rice in the polishing room 6 starts to become clogged due to the humidity of the brown rice, the load on the main motor 9 increases rapidly, and the current value exceeds the set value, that is, the dangerous value. Then, the comparator CM outputs the alarm processing unit CP to the alarm processing unit CP.
Turns off the switch of the main motor 9 to stop the operation of the rice milling machine 2, and gives an alarm by sound and an alarm by lighting the alarm lamp LC.

Therefore, the operator hears the alarm or sees the alarm light LC, that is, the operator knows that it is in a state.
The operator holds the handle 59 to open the front door 35, closes the shutter S, and sets the uneven rice receiving container under the drop gutter 26.

Next, the clogging release button 25 is pressed. When the button 25 is pressed, the geared motor 19 is started, the cam shaft 18 is rotated, and the resistance disc 13 is retracted, so that the resistance becomes zero. When the operation controller 57 detects that the resistance has become zero by the encoder 20, the operation controller 57 turns on the switch of the main motor 9 to start the operation.

Then, since the rollers 7 and 8 rotate, the white rice R in the whitening chamber 6 is discharged from the rice polishing outlet 11,
Pass through the drop gutter 26 and enter the uneven rice receiving container. At this time, that is, in the initial state, and since the white rice R is not completely clogged and hardened, the white rice R in the polishing chamber 6 can be easily discharged.

When the blockage is eliminated and the brown rice G is lost in the connecting gutter 5, the light of the light emitting portion L1 of the photosensor L enters the light receiving portion L2. Therefore, the light is received from the light receiving unit L2 and output to the operation control unit 57, and the control unit 57 stops the operation of the main motor 9.

After holding the upper lid handle 51 to open the upper lid 52, the uneven rice receiving container is lifted up, and the uneven rice in the uneven rice receiving container is returned to the brown rice hopper 4. After the front door 35 is closed and the whiteness of the automatic resistance device 12 is adjusted, the shutter S is opened and the start button 57a is pressed to return to the standard operation.

Further, the maintenance will be described. When cleaning the fried grain cylinder 36, as shown in FIG.
Open to expose the fried cylinder 36. When the bolt 39 of the tightening band B is removed, the fried food cylinder 36 is divided into the vertically divided cylinder portions 36a and 36b as shown in FIG. In this way, since the tubular portions 36a, 36b and the screw 37 can be separated,
It can be easily cleaned. After cleaning, both cylinders 36
Align the a and 36b with the flange 36f, wind the tightening band B, and tighten the bolt to return it to the original state.

When cleaning the cyclone 3, the hook 3
1 is disengaged from the locking portion 29a, the pressing lid 30 is opened, the straight cylindrical portion 3A of the cyclone 3 is grasped and lifted out of the fitting portion 29. After the cleaning is completed, the cyclone 3 is fitted to the fitting portion 29, the pressing lid 30 is closed, and the hook 31 is locked.

6, a broken rice sorting unit 71 is provided, a broken rice collecting chamber 73 is provided outside the sorting unit 71, and a downflow gutter 74 is formed in the collecting chamber 73. A slit 71a is formed in the sorting section 71. The slit 71a is for sorting the white rice R and the broken rice SR, and is formed in a size that allows only the broken rice SR to pass.

Instead of forming the slit 71a in the selecting section 71, this portion may be a net. The sorting unit 71 is formed in the upper half of the fried food container 36, but the range of formation thereof can be appropriately selected as necessary. Further, the fried grain cylinder 36 does not necessarily have to be formed by a plurality of vertically divided cylinders, and may be a single cylinder.

In this embodiment, the crushed rice SR rising in the fried grain cylinder 36 together with the white rice R is discharged from the slit 71a of the sorting section 71 to the outside of the cylinder, falls into the crushed rice collecting chamber 73, and falls down the gutter 74. Pass through the broken rice container 75. Therefore, since the broken rice SR is not mixed in the white rice R discharged from the rice discharge port 38, the commercial value of the white rice can be increased.
