Air draft hot air apparatus (11 ') of Hot-blast Heating and the air draught hot air apparatus of two Hot-blast Heatings with the inner sucking-off of aspiration channel (10)
(11) ingredient conveyor (7) of pipeline chain-type is blown into after, then enters back into the cylinder (1)；Or raw material storage tank (4)
In the raw material dried of needs sent into by raw material discharging electronic rotation valve (5) that raw material storage tank (4) is equipped with funnel below
The entrance of the ingredient conveyor (7) of pipeline wind-driven type, is then passed through with from the cylinder with the wind that drying aerator (6 ') blows out
(1) air draft hot air apparatus (11 ') of inner Hot-blast Heating out and the suction of two Hot-blast Heatings with the inner sucking-off of aspiration channel (10)
The ingredient conveyor (7) of pipeline wind-driven type is blown into after wind heat wind apparatus (11), subsequently into the cylinder (1)；Or raw material
The inner raw material of storage tank (4) sends into spiral shell by raw material discharging electronic rotation valve (5) being equipped with raw material storage tank (4) below funnel
The entrance of rotating ingredient conveyor (7), is then sent to the cylinder (1) by screw type ingredient conveyor (7) raw material inner,
Aerator (the 6 ') wind that blows out is dried through one with the air draft hot air apparatus from the inner Hot-blast Heating out of the cylinder (1)
Screw type raw material is blown into after the air draught hot air apparatus (11) of (11 ') and two Hot-blast Heatings with the inner sucking-off of aspiration channel (10) defeated
Send machine (7)), then enter back into the cylinder (1)；Or the raw material in raw material storage tank is passed through raw material storage tank (4) below
It is inner that raw material discharging electronic rotation valve (5) being equipped with funnel is directly sent to the cylinder (1) material, dries aerator (6 ') and blows
The wind for going out uses aspiration channel through one with the air draft hot air apparatus (11) from the inner Hot-blast Heating out of the cylinder (1) and two
(10) the air draught hot air apparatus (11) of the Hot-blast Heating of inner sucking-off are directly blown into the cylinder (1).
