a granulating plate 71 fixed on one side of the pressurizing ring 6 and provided with a plurality of granulating holes;
a cooling plate 72 fixed on one side of the granulating plate 71, wherein a sleeve hole 73 is formed between the cooling plate 72 and the granulating plate 71, and the cooling plate 72 has a hollow structure;

In a preferred embodiment, the oscillating assemblies 77 are perpendicular to the water flow direction.
As a preferred embodiment, the oscillating assembly 77 comprises:
