The gap control of the de-silicification wheels 3, 3 is such that so-called load control is performed at the beginning of the work, and when the sample grains to the de-silicification rate sensor 19 reach a steady state, the control is switched to the de-latitude rate control. A current transformer 52 is provided in the middle of the drive motor 43 circuit to constantly detect the load current of the motor 43, compare the load current with a preset reference value, and control the control motor 4 in forward and reverse directions for a certain period of time. After the elapsed time.

The output of the de-Il removal rate sensor 19 is connected to the rotary switch 4.
This configuration switches to so-called load control in which the control motor 4 is interlocked in forward and reverse directions to match the set silicon removal rate while comparing it with a set value of No. 7 (for example, a silicon removal rate of 85%).

The rotation of the rotating sorting tube 20 is controlled by comparing the output result of the rru rotation speed detection sensor 41 with the set rotation speed (for example, 50 rpm) of the rotary switch 48, and interlocking the rotation speed control motor 31 in forward and reverse directions. The number of revolutions can be maintained constant at all times.

When both the buzzer stop switch 46 and the start push button switch 44 are turned on, the control section in the operation panel 42 switches to the test run mode and a series of test run operations can be performed. 43 by rONJ of the stop push button switch 45.

When starting the hulling sorting work, when both the buzzer stop switch 46 and the start push button switch 44 are turned on,
The test operation mode is entered, and the operations ① to ② described above are performed before paddy is supplied, and the operator can confirm whether the operating conditions of each part are normal or not. After the test run of each part, it is determined that normal operation is possible, and the stop push button switch 45 is turned on to stop the test run, and the main work begins.

When paddy is supplied to the supply funnel 2, this paddy is defed and 70-ru 3
, 3, the deflated and wind-sorted mixed rice passes through the mixed rice guide tube 28. The mixed rice is supplied into the sorting@i20 through the transfer gutter 21 and the like.

The sorting cylinder 20 scoops up the mixed rice through the pot holes 23 and 23 while still rotating, and the brown rice passes through the finishing valve 29 and is collected into the finishing rice gutter 22, while the long-grained paddy has a high center of gravity and is placed in the pot at a relatively low position. It falls out of the hole and returns to the mixed rice layer.

Sorting fi20 starting end side The above sorting is repeated over the starting end line end side to separate paddy and brown rice. In addition, for brown rice, the receiving gutter is 33°, and the brown rice gutter is 3.

In addition, the paddy remaining at the end of the sorting tube 20 (including some brown rice) is
It is scooped up by the grain lifting blades 37 and 37 and flows down to the opening 40 side.

The grains that have passed through the opening 40 are returned to the two parts of the supply funnel and are again subjected to desiliconization and wind selection treatment.

During the above work, the desiliconization rate sensor 19
The detection result and the set value are compared, or the selection tube 20
The detection result of the rotation speed detection sensor 41 and the set value are compared so that the rotation speed also becomes the set rotation speed.

In addition, when an abnormality occurs such as overload detection of the motor 43 by the current transformer 52, detection of no paddy in the supply funnel 2 by the grain presence/absence sensor 9, and detection of development 1 by the roll development sensor 11, the corresponding LEDs 50, 50, etc. lights up and a buzzer sounds at the same time to alert the operator.

The test run operation of this embodiment has been described for the case of a rice huller and sorter, but it can also be performed for other grain dryers, for example. In this case, the buzzer stop switch that notifies you of poor paddy flow, motor overload, burner abnormality, etc. and the start switches for loading, drying, and discharging should be set to "O" at the same time.
It is best to do a trial run of each task and then start the main work.
