The specific embodiment
Below in conjunction with accompanying drawing, the technical scheme of the utility model is done further explanation.
Shown in Fig. 1 a, Fig. 1 b; A kind of closed air blast drying unit comprises air blast 3, elevating mechanism, Jar opening sealer device, telescopic air intake tube 4, telescopic chimney fan 5, pressure safety valve 6, pressure transmitter 7, photodissociation catalytic oxidizing equipment 8 and air-introduced machine (not shown) of control device, band heater or the like.
