It is dynamic to advance.
Three, after the heating devices heat that heat-conducting medium passes through peripheral hardware, the thermal energy that heat-conducting medium carries directly passes through heated type
The heat transfer of helical blade 8, heat radiation carry out thermally conductive heating to material around cored screw blade, the object in roller drying storehouse 1
Material has obtained the thermally conductive heating of thermal energy.
Four, the moisture that the moisture vaporization in roller drying storehouse 1 when dry materials in material generates is by exhaust pipe 13 by true
Empty unit pump drainage is gone out；After material carries out vacuum drying drying in roller drying storehouse 1, reach necessary requirement water content standard
Material.
Five, material passes sequentially through the bellows elbow 20 of the discharge port 5 in roller drying storehouse 1, discharge device 9 after drying, and closes
Roller drying storehouse 1 is discharged in wind device 19.
Above embodiments are merely used to help understand the production method and its core concept of the utility model, and specific implementation is not
Be confined to above-mentioned specific embodiment, those skilled in the art from the above idea, without creative labor, institute
The variation made, all falls within the protection scope of the utility model.
