In the processing of PET,one of the most important and critical factors is drying step. To obtain maximum product performance, it is essential to reduce the moisture content. The material should be nearly free from moisture. Besides, as wet chip is in amorphous form,it clumps when dried at normal drying temperature. Therefore. amorphous PET chip has to be crystallized before dried. WELLSUN Dryer System keeps pace with the international advanced technologies. It is reliable, automatic and simple.
