the wind speed of the positive pressure fan (7) can be controlled by controlling the electric box (9) in the drying process;
3) discharging: the not dry material of this part need be earlier discharged through unusual escape orifice (32) in storehouse (22) falls into discharge pipeline (3) through arris platform shape in the dry storehouse of initial stage (1) part, the dry back of accomplishing of material, send out the dry good material of part through sample connection (33) earlier, send into totally closed moisture tester (8) and detect the material water content, if the water content is not up to standard, continue to carry out drying operation, if the water content is up to standard, can open through control electronic box (9) control bleeder valve (31), send out the collection with the good material of drying, when the position of material arrival dry storehouse (1) unloading position sensor (18) in dry storehouse (1), can close bleeder valve (31) and stop the ejection of compact.
9. The drying method of the intelligent hybrid dryer according to claim 8, wherein: during the drying operation, the air stop valves (5) of two air inlet pipes (4) which are arranged diagonally can be opened simultaneously, the two air inlet pipes (4) are closed after air is introduced for a period of time, the air stop valves (5) of the other two adjacent air inlet pipes (4) are opened, the air stop valves (5) of the two air inlet pipes (4) are opened in pairs in sequence, in the drying operation mode, hot air enters the drying bin (1) from the air distribution holes (211) of the two air distribution inclined plates (21) which are arranged diagonally at the same time, the hot air is closed after entering for a period of time, the air distribution inclined plates (21) which are arranged diagonally next to the wall circulate the hot air, by adjusting the on-off time of the air stop valve (5), the materials in the drying bin (1) can generate centrifugal force along with the switching of hot air, the materials can rotate in the drying bin (1), therefore, the materials turn upwards under the action of hot air and can rotate along the inner wall of the drying bin (1).
10. The drying method of the intelligent hybrid dryer according to claim 8, wherein: the air-lock valves (5) of at least three air inlet pipes (4) can be opened according to the situation during the drying operation.
