    摘要: A vacuum drying method wherein a solution of a material to be dried which has been adjusted to 1-50 centipoise, is supplied to a steam-heated long tube, solid-vapor mixture of powdery dry material and vapor produced in the tube is blown out under reduced pressure, and the powdery dry material and vapor are separated so as to obtain powdery dry material.
