This feeding control device 500 can last to provide the material for the rice mill unconsciously to can not let the indoor pressure of whitening unbalance, can reduce the production of broken rice and the incomplete scheduling problem of brown rice processing. This feeding control device 500 need not manual operation, and labour saving and time saving can make the brown rice last slow entering whitening chamber, and auger delivery 2009 can not receive the damage, also can not let the brown rice spill over, and it can be automatic flow into the whitening chamber with the brown rice in, let the rice mill can work the husk rice always to can ensure that the rice of producing is of high quality, wherein the slot has played fine location and supporting role, and adopt direct current motor, the drive is reliable and stable.
In this embodiment, the horizontal cross-sections of the cavity, the rice screen and the sand roller are circular, and the whitening chamber and the bran discharging chamber are both annular.
Particularly, the annular whitening chamber and the annular bran discharge chamber are beneficial to the circulation of air flow.
While embodiments of the present invention have been described above, the above description is illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
