Alkaline noodle loosening device of automated production was designed, and the overall scheme was then researched. It was carried out the research on the structure design of roller with multiple stirring rod, wheel and bracket, conveyor belt and so on, and its parameters were given. Alkaline noodle loosening device waas modeled by using Adams software. The rationality of the design was verified through kinematics simulation from the two aspects such as rotary speed and angular acceleration of the roller. The contact force of the conveyor belt and contact force of the roller were tested through dynamic simulation, providing the reference for optimization design of alkaline noodle loosening device and building automatic production line of alkaline noodle.
