By traditional technology fiber dewatering and impurity removal is different processes managed by two different machines. Workers collect the fiber from decorticator and sent it into dewaterer, and then impurity removal. This technology is in low efficiency and requires more manpower. Based on this situation, we design and manufacture this fiber dewatering and cleaning machine. When the fiber comes out from the decorticator, it will be sent to this machine for dewatering and cleaning automatically.
