[0027] When using the equipment, the staff first puts the items into the drying drum 160 through the loading port 210, and then turns on the motor 220, which drives the stirring blade 250 to rotate. When the items are dried for a specified time, the processing is stopped, and then the items are discharged to a specified place through the discharge port 130 by the pump 120.

[0028] When the stirring blade 250 is used for a long time, since polyester items are not suitable for use with hard stirring objects, the stirring blade 250 will be deformed and more items will remain after long-term use, and it needs to be replaced. When replacing, the staff can directly pull the stirring blade 250. When pulling the stirring blade 250, the stirring blade 250 will be deformed, so that the staff can remove the stirring blade 250 more conveniently.

[0029] In this embodiment: when the articles are dried, the stirring blades 250 and the transmission shaft 230 are installed. During the drying process, the articles are put in through the loading port 210, and then the motor 220 is turned on, so that the motor 220 drives the stirring blades 250 to rotate, and the articles in the drying tank 240 are stirred. Then, when the drying drum 160 is heated and dried, the articles are stirred so that the heat is more evenly distributed. Compared with the existing static drying device, the drying drum 160 can shorten the processing time for drying the articles, thereby making the drying efficiency higher.

[0030] Embodiment 2: This embodiment is intended to promote the solution of the problem in the prior art that when the drying process is carried out for a long time, items will remain on the drying stirring blade 250.

[0033] In the present embodiment: when the stirring blade 250 in the drying drum 160 is used for a long time, objects will be attached to the stirring blade 250. If it is not replaced, more and more objects will be accumulated during the later use, which will affect the subsequent use. Through the setting of the locking assembly 370, when the stirring blade 250 needs to be disassembled and replaced, the staff can directly pull the stirring blade 250. Since the equipment is used to process polyester products, it is not suitable to use harder stirring objects. Therefore, when the stirring blade 250 is pulled, the stirring blade 250 will be deformed, which is more convenient for disassembly.
