This utility model discloses an automatic drying and dehydration device for seaweed, relating to the field of seaweed dehydration technology. It includes a rotating shaft, which is rotatably mounted to the rear end of a drying chamber via bearings. A limiting plate is installed on the outside of the rotating shaft and welded to it. The device allows the rotating shaft to rotate by installing a drying basket, causing the seaweed inside the basket to rapidly dehydrate under centrifugal force, thus improving the drying efficiency. When the drying basket centrifuges the seaweed, the seaweed adheres tightly to the inner wall of the basket under centrifugal force. Because the drying basket has a mesh structure with many gaps, the seaweed adheres to the inner wall. Combined with the centrifugal force acting on the seaweed, this effectively overcomes the strong hot air blown by the hot air dryer, preventing the seaweed from flying around and breaking, thus allowing the seaweed to be dried at the highest speed.
