Further, the feed cylinder is cylindrical and is the horizontal arrangement, a plurality of supporting legs are located to the feed cylinder. Thereby guarantee the steady transmission of the material in the feed cylinder.

Further, a first fan and a first heating unit are arranged at the first air inlet pipe; and the air inlet main pipe is provided with a second fan and a second heating unit.

The plurality of air inlet areas are divided into a plurality of first air inlet areas and a plurality of second air inlet areas, the plurality of first air inlet areas are positioned on one side of the first air inlet hood, and the plurality of second air inlet areas are positioned on the other side of the first air inlet hood; the plurality of first air intake regions are distributed at equal intervals, and the plurality of second air intake regions are distributed at equal intervals.

Further, a plurality of air outlet areas are arranged at the position of the charging barrel, and each air outlet area is provided with a plurality of air outlet holes.

Furthermore, the number of the air outlet areas is equal to that of the second air outlet covers, and the air outlet areas and the second air outlet covers are in one-to-one correspondence.

Further, the air outlet area is positioned at the top of the barrel.

The air outlet area can facilitate the outflow of the dry air from the second air outlet cover. Of course, in the case that the air outlet area is not provided, the drying air flow of the second air outlet cover can be exhausted from the top of the drying bin.

Has the advantages that: the application discloses drying device can carry out quick drying process to the polymer particle that medical catheter's preparation was used to carry while dry, and the aggregate is detained in stoving cabin department in transportation process, thereby fast drying, drying efficiency is high, and it is effectual to dry.
