[0002] The statements herein only provide background technology related to the utility model and do not necessarily constitute the prior art.

[0003] After the screw extruder extrudes the strip, the strip needs to be water-cooled first, and then cut into plastic particles by a pelletizer. Since the surface of the strip just output from the cooling tank is attached with water droplets or water film, in order to not affect the cutting effect of the pelletizer and avoid particle adhesion, a hot air drying device is currently added between the pelletizing and water cooling processes to remove the moisture on the surface of the strip.

[0004] However, since the moisture content attached to the surface of the strip is different, it is difficult to control the drying time when hot air drying is performed, and there may be a situation where part of the strip is dried while the remaining part of the strip is not dried. If drying continues at this time, there is a risk of strip breakage. Therefore, in order to improve the uniformity of strip dehydration and drying, a strip dehydration device is proposed to solve the above problems. SUMMARY
