This invention discloses a vertical mixing dryer, relating to the field of dryer technology. A motor drives spiral blades to rotate, thereby conveying material. The material is thrown out by centrifugal force at the tip of the spiral blades and impacts an axially movable dispersion hood. With the assistance of a gas spring and an adjusting unit, when the material has high moisture content and a large impact force, the dispersion hood is lifted.
