The invention provides a rotary type rice
drying and screening device. The rotary type rice
drying and screening device comprises a lifting bin, a movable bottom plate is arranged on the bottom of thelifting bin, a lifting mechanism is arranged in the lifting bin, a lifting bin outlet is formed in the top of the lifting bin, a first filter screen is arranged under the lifting bin outlet, and a screening blower and a sorting slope are arranged below the first filter screen. A
drying bin is arranged below the filter screen, a drying cavity is formed in the drying bin, an annular gear is installed on the drying bin, and the annular gear is matched with a rotary gear. A bottom drying blower is arranged on the bottom of the drying cavity, a plurality of
peripheral drying blowers are uniformlyarranged around the drying bin, the sorting slope is connected with a screening pipeline, the
tail end of the screening pipeline is communicated with a division pipeline and a dust collection pipeline, a second filter screen is arranged at the communication position of the dust collection pipeline and the screening pipeline, and a
dirt collection pond is arranged at the
tail end of the dust collection pipeline, so that impurities in rice are filtered in the drying process of the rice, dust in the rice is precipitated, and contaminations are effectively reduced; due to rotation of the drying bin, drying is more uniform; due to the drying cavity, the heating area of the rice is increased, the drying efficiency is improved, and the drying quality is improved.
