Centrifugal dehydrating technology with alcohol displacement method is widely applied for nitrocellulose dehydrating at home at present, and can’t fulfill the requirement of some follow-up process. In consequence, a kind of automatic efficient production line for nitrocellulose dehydrating based on vacuum dehydrating with hot wind technology is designed. Principles of techniques, process flow and constitution of the production line is introduced ,and three kinds of key technology is expanded on intensively, including control mode to ensure the compatibility of moisture content in the dehydrating nitrocellulose, pipe-line transportation technology of nitrocellulose pulp and technology for ensuring the safety of production line, and a series of measure is adopt to insure the quality of nitrocellulose dehydrating, continuity and safety of production. The production line has been applied with good performance now, which has higher dehydration efficiency, safety, advancement, and lower labor intensity and environmental pollution.
