[0002] Polyacrylamide is a linear polymer with wide applications in many fields such as oil extraction, water treatment, textiles, and papermaking. Drying is one of the crucial steps in the production of polyacrylamide.

[0003] Due to its high viscosity, polyacrylamide is prone to clumping during the drying process, even with low-temperature drying. Clumping not only severely affects the product's appearance, making the surface uneven and rough, but also alters the particle size distribution, leading to inconsistent particle size and significantly reducing solubility, thus drastically lowering product quality. More seriously, clumping creates numerous difficulties for subsequent processing and use, such as clogging pipes during transportation and preventing complete dissolution during use, thus affecting performance. Therefore, developing a device to effectively prevent polyacrylamide clumping during low-temperature drying is of significant practical importance.
