Abstract

PROBLEM TO BE SOLVED: To prevent the generation of broken rice and blackish milled rice while a customer does not know that the moisture of grains are not suitable for husking and milling by allowing an operator to select whether the work is suspended or continued when the moisture of the grains is displayed to be off the set range. SOLUTION: The stop signals for the respective devices of the unmanned husking and rice milling device are once outputted when a detection signal is inputted to a control section 45 upon detection that the grains have the moisture content off the set range. On the other hand, the detection signal is inputted to a control section 80 separate from the control section 45. The control section 80 comprises the means for displaying that the fed grains have the moisture content off the set range and the means capable of outputting speeches. When the detection signal is inputted to this section, the section outputs the display by a speaker 85. The speeches like 'stop the work and push a return button if you wish to have the unpolished rice returned or push a processing continue button if you wish the continuation of the work' are outputted to allow the customer to select whether the work is continued or stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an unmanned rice milling facility for milling brown rice brought in by customers and an unmanned rice milling facility for milling rice.

[0002]

2. Description of the Related Art After a customer puts grains such as paddy or brown rice into a raw material input hopper, puts a fee into a coin mech and selects a degree of milling, the paddy goes through a hulling operation by a hulling machine. In the case of unpolished rice, an unmanned rice milling facility or an unmanned rice mill for supplying white rice directly to a rice mill for whitening and discharging white rice to a white rice tank is well known. In addition, a technique relating to an automatic rice milling device that stops the hulling work and returns the input paddy and a fee when a high moisture content paddle that is equal to or higher than a set reference value is detected by a moisture meter is disclosed (JP-A-6-269688). ).

[0003]

For example, if a high-moisture paddy is to be converted into white rice, the rice cannot be sufficiently slid during the hulling operation by a hulling roll of a huller, and as a result The effect is not sufficient, resulting in white rice with a color darker than the set whiteness. Also, if brown rice with a low moisture content is converted to white rice, the rice is liable to crack during the whitening operation, and so-called broken rice is often generated.

In such a case, the customer may not be aware that the grain brought by the customer is a grain having a high or low moisture as described above. As a result, troubles may occur with the manager of the unmanned rice mill facility over the white rice that has come out after being milled. On the other hand, even if you know that the grain you bring in is high grain or low moisture grain as described above and is not suitable for milled rice or polished rice, the customer who wants to turn it into white rice anyway Also exists. This is caused, for example, by the desire to turn white rice in an unmanned rice milling facility, because high-moisture paddy is troublesome in the drying operation by a drier when an end amount of undried rice is generated. Brown rice is over-dried rice due to failure of the drying operation by the dryer, resulting from forced whitening.

The present invention, as described above, prevents the generation of broken rice or black and white rice without the customer knowing that the grains contained therein are water unsuitable for milled rice, The purpose of this facility is to provide an unmanned rice mill that meets the needs of a variety of customers who want to make white rice anyway, even if the customer knows that the grains contained in the rice are water that is not suitable for rice milling. .

[0006]

The present invention employs the following technical means to achieve the above object. The invention according to claim 1 includes a raw material input hopper 2 for inputting grains, a rice milling machine D for whitening the grains input to the raw material input hopper 2,

Unmanned paddy, comprising: display means for displaying when a grain is detected, and selection means for the worker to select whether to stop or continue the work when the display indicates that the grain is moisture outside the set range. A rice mill was used.

[0008]

When the customer inputs, for example, a fee or a card, and inputs the grains into the raw material input hopper 2, the unmanned rice milling machine or the unmanned rice milling machine is started, and the milling or milling operation is performed. Be started. At this time, when the moisture meter 77 detects moisture out of the set range, for example, high moisture of paddy or low moisture of brown rice, it indicates that the grain is not moisture suitable for work. At this time, if the customer desires a return and presses a return button 81, the input kernel and the fee are returned. Regardless of the display, the customer who wants to continue the work presses the processing continuation button 82 to continue the rice polishing operation or the hulling rice polishing operation.

[0009]

According to the present invention, when the customer does not know that the input grain is water unsuitable for milled rice or milled rice, the work is continued or stopped after indicating so in advance. By letting customers choose
There is no possibility that the grain that has been milled or crushed and comes to the white rice tank 4 without the customer's knowledge is black white rice having a color lower than the set whiteness, or a large amount of broken rice is generated. Therefore, there is no trouble between the customer and the manager of the unmanned rice polishing machine. Also,
If you know that the grain input by the customer is not suitable for rice milling or milling, and wish to process rice milling, you can choose to continue the operation to respond to various customer requests It can be an unmanned rice mill.

3) When the whiteness selection switches 44a, 44b, and 44c are selected (STEP 4), each unit of the apparatus starts operating, and the grains charged into the raw material charging hopper 2 are charged into the chaff tank 10. In the paddy tank 10, a moisture meter 77 is provided,
Then, the water content of the introduced grain is detected (STEP 5).
At that time, it is detected that the grain is water outside the set range (for example, 18% or more for rice and 12% or less for brown rice) (STEP 6), and the detection signal is input to the control unit 45. First, a stop signal of each device of the unmanned rice milling device is output (STEP 7). On the other hand, the detection signal is input to a control unit 80 different from the control unit 45. The control unit 80 is a means for displaying that the input kernel is water outside the set range, and in this embodiment, is configured to be capable of outputting sound. When the detection signal is input, a display is output by a speaker 85 (for example, "The brown rice has low moisture. If the rice is polished as it is, the rice will be broken.") (STEP)
8). Next, "If you want to stop the work and return the brown rice, please press the return button. If you want to continue the work, please press the processing continue button. And the like, and prompts the customer to select whether to continue or stop the work (STEP
9). At this time, the customer who wants to return the grains presses the return button 81. Then, in response to a command signal from the control unit 45, the switching shutter 70, a switching valve (not shown) provided for the rice mill 21 and the hulling elevator 6, the destoning machine G, the rice mill 21 and the like are operated, and the grain is moved. Is conveyed to the bypass 75, the crusher G, and the milling machine 21, and is discharged from the milling machine 21 through the switching channel 83 to the white rice tank 4.

On the other hand, the customer who wishes to continue the work presses the continue button 82. Then, in response to a command signal from the control unit 45, the devices that have been once stopped start to be driven again, and the rice milling process is performed. In addition, the display means for displaying that the input grain is water outside the set range is not LED,
Needless to say, it is also possible to display characters such as.
