There is a quill shaft stirrel to mix in low speed. And make the slice remain small relative movement to prevent the slice felt. It is to make good condition for high-temperature drying. It has blast-type electric heating devices, the air will be into the hopper room as befitting temperature from quill shaft by temperature adjuster. The hot air will make every resin particles soakage through the layers of materials, along all the way to exchange heat, Keep away moisture. Resin particles will be dryed continually in the top-down process, keep away the planar water which is in the surface to produce 35 per cent of crystallinity of the slice. Then the air will be exhausted from the top of the machine. So as to complete a highly efficient drying process.
