The above-described technique has the following problems:

the production line is continuous uninterrupted processing, no rice leakage detection is carried out in the production line, especially in a fine grinding machine, when rice grains are mixed into bran in the production line, the rice grains cannot be known in time, and then a large number of rice grains are possibly discharged by mistake.

The combined rice mill in the prior art is provided with a rice huller which is grain processing machinery of brown rice, and can remove rice hulls, reduce the burst of rice and the damage of the skin, and keep the integrity of the brown rice as much as possible. However, the prior art huller cannot adjust the distance between the two rubber rolls in real time. When the grain sizes of the paddy are inconsistent, partial paddy is broken, and the processing yield is low.
