The invention discloses a composite tobacco manufacturing technology based on big data, comprising a cabinet fixed on the ground, a bake chamber is fixedly arranged in the cabinet. The right end of the bake chamber is communicated and provided with a rotary disk chamber, and the left end of that bake chamber is communicated with and provided with a rotating chamber. A swing motor is fixedly arranged on that right end wall of the rotary table cavity, the left end of that output shaft of the swing motor is fixedly provided with a rotary table which is rotatably connected with the rotary table cavity, the left end of the rotary table are fixedly provided with a plurality of store rods arranged in a ring shape, the placing rod extends leftward through the baking chamber and extends into the rotating chamber to be slidably matched with the inner wall of the rotating chamber. The rear end of the bake chamber is fixedly arranged in the cabinet. The device of the invention has a simple structure, and is convenient to use. The equipment adopts semi-digitalized control, dries tobacco with heated air after drying, sprays additive evenly with atomizing nozzle, and controls the process of cutting tobacco with blade by motor, thus improving the technological property and production efficiency of the equipment.
