The air vent of conducting；
The air outlet of air blower connects with vented cavity；
Locker room is provided with second circulation mouth and discharge gate；
Cycling mechanism is connected to the cereal in locker room being delivered to pre-heating cabin with locker room；Cycling mechanism includes circulation
Pipeline and circulating pump, the import of circulation pipe are connected with second circulation mouth, and the outlet of circulation pipe connects through circulating pump and first circulation mouth
Connect.
Preferably, the interior port of export positioned at first circulation mouth of pre-heating cabin, which is connected with, makes cereal uniformly spill dividing equally to surrounding
Device.
Preferably, discharge gate is arranged on the bottom of locker room.
Preferably, the bottom of locker room is funnel-form, and discharge gate is located at the least significant end of funnel.
Preferably, second circulation mouth is arranged on locker room bottom close to the position of bottom.
Preferably, the first strip channel and the second strip channel are mutually perpendicular to.
In the present invention, pre-heating temperature elevation is carried out to cereal by pre-heating cabin, and due to being provided with the between pre-heating cabin and warehouse for drying
One strip channel, the heat of warehouse for drying by the first strip channel into pre-heating cabin be pre-heating cabin heat supply, and the cereal in pre-heating cabin
Then it is affected by gravity and warehouse for drying is slowly flowed into by the first bar hole automatically, the shape setting of the first bar hole extends paddy material and existed
Residence time in pre-heating cabin；Paddy can be made to flow uniform and scattered inflow warehouse for drying simultaneously, reduce the circulation thickness of grain, increase
The contact area of grain and thermal current, so as to improve drying effect；Cereal drying storehouse is carried out after tentatively drying by Action of Gravity Field
Automatically flow into tempering storehouse to cool down, being delivered to pre-heating cabin again by cycling mechanism again after cooling carries out secondary drying, leads to
This circulating drying mode is crossed it is possible to prevente effectively from the water evaporation rate on cereal grain top layer caused by direct high temperature is dried
It is far longer than interior kernel moisture diffusion speed and forms the problems such as being charred phenomenon, crackle, crushing, so as to improves grain-drying
Quality afterwards, and gravity is relied primarily in the present invention and is flowed between each storehouse, power consumption is relatively low.
