Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a rice hulling and rice milling device comprising a hulling process and a rice polishing process.

[Prior Art and Problems to be Solved by the Invention] Unmanned rice-hulling facilities that have both a hulling function and a rice-polishing function have become popular in recent years. By the way, the rice milling machine finishes the rice to a predetermined degree of polishing by ensuring a predetermined pressure by a resistance plate at the outlet of the milling chamber.

Therefore, at the end of the work, a small amount of polished brown rice or unpolished brown rice remains in the milling chamber. Since the rice is milled by removing the hull, in extreme cases some of the paddy or chaff may remain.

If the rice milling machine is operated in order to start the next operation with the remaining grains as described above, there is a drawback that the remaining grains are discharged from the outlet without being subjected to polishing pressure and are mixed in the polished rice.

[Means to solve the problem]

For this reason, the first invention is provided with a huller that receives the supply of paddy and processes it for desiliconization, and a rice miller that receives the ground rice from the huller and processes it for polishing. The rice milling device for removing hulled rice is provided with a timer means for starting the motor for driving the rice milling machine after a predetermined period of time has elapsed.

Further, the second invention is provided with a huller that receives and persuasively processes paddy, and a rice miller that receives and polishes the scraped rice from the huller, which drives the rice miller. The rice hulling and rice milling apparatus is configured such that the drive motor is activated based on a detection result of a detection means that detects that a predetermined amount or more of grain to be milled is filled in a milling chamber.

[Operation and effect of the invention]

The first invention is that the rice milling machine motor 40 is started after the timer means has timed up after starting hulling, and the rice milling machine motor 40 is activated after the timer means has timed up after starting hulling, and removes residual grains of rice that have been previously processed and remains in a conveyance unit such as an elevator, and rice that has been newly processed for hulling. The grains supplied will be filled in the whitening chamber 34 for a while. Therefore, when the rice milling machine 12 is started, the internal grain pressure is sufficiently accumulated, and the milling roll 35 can perform a sufficient milling action.

In addition, in the second invention, the milling chamber 3 is installed in the supply tank of the rice milling machine, etc.
Since it is configured so that it can be directly confirmed using a detector that the grain volume state into the grains 4 is equal to or greater than a predetermined amount, the whitening action by the whitening roll 35 can be sufficiently performed in the same way.

Set. After completing these setting preparations, the paddy is put into the input hopper 8. At the same time as coins are inserted, the supply spiral motor 18 and the huller motor 3 are
1. The motor 66 for the hulling elevator 9 and the rice milling elevator 11 starts operating, and the paddy from the input hopper 8 is transferred by the supply spiral 16 and supplied into the hulling elevator 9.

The paddy discharged from the elevator 9 is transferred from the paddy tank 20 to the desiliconizing rolls 24 and 25 of the hulling machine 10 by the switching shutter 21 which is set in advance at the inclined posture port in accordance with the above-mentioned "massaging" setting.
Supplied on top. The raw material paddy is persuaded by the rotation of the desiliconizing rolls 24 and 25, and as it passes through the wind screening section 29 below, light chaff and grains are removed. supplied within.

The time-limited operation starts from the time when each of the above-mentioned motors starts, and when the built-in timer means counts up the clock signal to a predetermined value, the rice milling machine motor 40 starts. In the rice milling machine 12, a polishing roll 35 rotates to remove the surface bran layer or rice husk from the sequentially supplied brown rice grains containing some unpersuaded grains with a bran removal screen 37, thereby turning them into polished rice. This polished rice passes through the polished rice take-out section 7 and is appropriately collected in the operation chamber 3.

As mentioned above, the rice milling machine motor 40 is activated after a predetermined time has elapsed by the timer means after the start of hulling, and it is used to remove grains of rice that have been previously processed and remain in a conveyance unit such as an elevator, The processed and supplied grains will be filled in the milling room 34 for a while.

Therefore, when the rice milling machine 12 is started, the internal grain pressure is sufficiently accumulated, and the milling roll 35 can perform a sufficient milling action.

When the time set by the input amount has elapsed, the drive motor 18 of the supply spiral 16 stops, and after a predetermined delay, the huller 10. If the rice milling machine 12 and the like are stopped, the amount of grain remaining in the elevators 9 and 11 and the milling room 34 can be reduced.

Next, when the raw material is brown rice grains, the "rice" selection button 60 is pressed to start work, but the switching shutter 21 in the paddy tank 20 is switched to the inclined position A, and the raw brown rice is directly milled. Rice milling machine 12 via elevator 11
