Description

[Detailed description of the invention] This invention relates to a single-pass rice removal machine.

In general, this type of rice milling machine is equipped with an opening/closing shutter on the raw material drop gutter at the bottom of the raw material tank to adjust the amount of raw material falling, and the paddy is polished in a milling room that communicates with the raw material drop gutter. White rice is obtained by sorting grains such as rice.

However, with this rice mill, it is difficult to uniformly supply an appropriate amount of raw material (paddy) to the milling chamber, and stable milling of the rice cannot be performed. Furthermore, it is difficult to remove the pods and bran from the rice grains, making it impossible to obtain polished rice with a beautiful finish.

In view of the above, the present invention aims to perform stable paddy whitening and obtain polished rice with a beautiful finish.

The present invention includes: an opening/closing shutter provided at the upper part of the raw material falling gutter; a falling amount adjusting plate provided in the middle of the falling gutter so as to be able to adjust the inclination angle and facing a falling amount adjusting roll; formed at the lower part of the falling gutter. a milling chamber which is made up of a feed roll, a milling roll, and a milling wire mesh that covers the outer periphery of the milling roll; a suction fan communicating with the milling wire mesh and interlocking with the falling amount adjusting roll; a resistance device at the milling chamber outlet; This is a one-time rice removal machine comprising: a polished rice drop port that communicates with the milling room through the white rice drop port; a thin layer drop port for white rice that is formed at the bottom of the polished rice drop port and communicates with the suction fan;

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a raw material tank, and an opening/closing shutter 3 is provided on the upper part of a raw material falling gutter 2 provided at the lower part of the tank, and a falling amount adjusting roll 4 having a protrusion formed on the outer periphery of a cylinder is mounted on the lower part of the tank. A V pulley 5 is fixed to the drive shaft of the adjustment roll 4.

Reference numeral 6 denotes a fall amount adjusting plate which is inclined toward the adjusting roll 4 side, and the upper part of the plate is fixed so as to be able to adjust the inclination angle. 7 is a whitening chamber provided at the lower part of the falling gutter 2, and this whitening chamber 7 includes a feed roll 8, a whitening roll 9, and a whitening roll 9 formed on the same axis.
It is constituted by a fine wire mesh 12 provided on the outer periphery of the. The milling wire mesh 12 is covered with a rice bran collection funnel 13, and the milling room 7
A polished rice dropping port 15 is provided through a resistance device 14 provided at the outlet 7a of the droplet 15, and a thin layer dropping port 15a of polished rice is formed at the lower part of the dropping port 15.
A and the Nukachi funnel 13 are communicated with each other. Reference numeral 16 is a driving motor with a shaft protruding left and right, a motor pulley 17 is fixed as a driving shaft on one side, and a suction fan 18 which is interlocked with the falling amount adjusting roll 4 is fixed on the shaft on the opposite side. The outer periphery of this fan 18 is covered with a fan case 19.

The fan case 19 is connected to the rice bran collection funnel 13 through a duct 20 and to the cyclone 22 through a pipe 21. In addition, in the figure, 10 is a drive pulley, and 11 is a main shaft pulley.

Next, to explain the operation, the opening/closing shutter 3
When opened, the paddy in the raw material tank 1 is transferred to the raw material falling gutter 2.
The raw material falls inside, is supplied to the gap between the raw material falling plate 6 and the rotating falling amount adjusting roll 4, and is further drawn into the rotating falling amount adjusting roll 4, passing through the gap and falling into the whitening room 7. The amount of paddy that falls into the whitening chamber 7 varies depending on the size of the gap; when the gap is large, the amount is large, and when the gap is small, the amount is small. This gap is adjusted by changing the inclination angle of the fall amount adjustment plate 6, and the closer the lower part of the adjustment plate 6 is to the fall amount adjustment roll 4, the smaller the gap becomes. The paddy supplied to the milling room 7 is transferred to the feed roll 8
The rice grains and rice bran are sent to the milling roll 9 where they are milled, and the rice hulls and bran are sucked through the milling wire mesh 12 into the rice bran collecting funnel 13 by the strong suction force generated by the rotation of the suction fan 18. , while pushing the resistance device 14 at the outlet 7a of the whitening chamber 7, the polished rice falls through the droplet 15, but the thin layer droplet 15a
Then, the white rice becomes a thin layer, and the light rice pods and bran are sucked into the rice bran collection funnel 13 by the suction force of the suction fan 18, and the heavy white rice is discharged out of the machine from the white rice drop port 15. The rice hulls and bran collected in the rice bran collection funnel 13 are discharged into the cyclone 22 through the duct 20 and pipe 21 by the pressure air discharged by the suction fan 18, where they are sorted into the pressure wind and rice hulls. Ru. Note that the rotational force of the motor 16 is transmitted from the motor pulley 17 to the main shaft pulley 1.
1, and is further transmitted from a drive pulley 10 fixed to the main shaft to the V pulley 5 of the fall adjustment roll 4.

As described above, in the present invention, the inclination angle can be adjusted in the middle part of the falling gutter, and the falling amount adjusting plate is provided, so that the paddy can be supplied uniformly and in an appropriate amount to the milling room, and the paddy can be stably supplied to the milling room. Paddy whitening can be done.

In addition, the milling wire mesh in the milling room and the part where the thin layer of white rice falls at the white rice drop port are connected to the suction fan, so the rice hulls and the pods of rice hulls are strongly sucked and separated from the white rice, resulting in beautiful finished white rice. can be obtained.

In addition, we have installed a suction fan that works in conjunction with the fall amount adjustment roll, so the fall amount adjustment roll rotates, and when supplying paddy to the milling room, the suction fan always rotates, preventing the bran removal wire mesh and the thin layer of polished rice from falling. Powerfully sucks out the paddy hulls, paddy hull pods, and bran. Therefore, it is possible to reliably remove the soil and bran from the rice hulls.
