Mouthful, the discharge port that sets below tank body, the feeding part for realizing Matter Transfer conveying, the blower fan for suction and blowing,
One wind for being used to blow out blower fan uniformly spreads the heating part of the horn cover of setting and the gas for heating blower blowout
Part etc., it is as follows the defects of the drying machine of this kind of structure:
1. because horn cover is generally disposed at the middle and lower part of tank body, so relatively being concentrated for tank body middle and lower part hot blast, generally
Middle and lower part temperature of charge can be caused higher and situation that top temperature of charge is relatively low, so as to the drying taste removal effect to plastic grain
It is unsatisfactory.
2. and due to temperature Centralized, often have because middle and lower part temperature of charge is too high, cause plastic grain to melt and then tie
The accident of block occurs.Drying machine bottom is concentrated on additionally, due to hot blast, in negative-pressure suction cyclic process, directly by part hot blast
Siphon away and be discharged into air, cause heat waste and influence operating environment.
3. in addition, generally hot blast is directly put from drying machine top to idle discharge, cause heat energy significant wastage and influence operation ring
Border.
4. the drying homogenizer of said structure, being generally independently operated, can not realize that plastic grain is granulated and homogenizing drying removes
Taste processing is synchronous to be carried out, and generally can not realize continuous production.
