Description

DETAILED DESCRIPTION OF THE INVENTION The present invention extracts a sample of rice with a substantially constant number of grains from the mixed wood after unweighing and drying, and detects the M ratio of brown rice and paddy in this sample rice using a general grain sensor. The present invention relates to an agitation rate measuring device for a huller that detects the deweighing rate at a dehulling roll.

Conventionally, when detecting the demixing rate using such a method, the greater the number of grains of sample rice, the higher the accuracy in detecting the constant demixing rate based on the grain size.

On the other hand, if the number of particles to be detected decreases due to foreign matter getting caught in the sample gutter's intake port or foreign matter adhering to the lens part of the sensor, the detection of the removal rate based on the number of grains will be extremely accurate. becomes bad.

The present invention has been invented in view of the above points, and includes a sample abnormality alarm device that is activated when the number of grains of sample rice detected by the general grain sensor during normal demixing work is less than a certain number of grains. Therefore, when the number of grains of sample rice falls below a certain level during normal demixing work in which sand grains are properly supplied to the demixing roll, the abnormal cost reporting device will be activated. Is the detection accuracy of demixing rate based on ? It is an object of the present invention to provide a demixing rate measuring device for a rice huller that notifies the operator and can always detect the demixing rate with high precision, thereby enabling accurate demixing work.
