The following raw material frompharm-aceutical industry,foodstuff industry chemical industry and so on can be dried. Suitable for pulpiness, paste-like misture of powder raw material. Thermal sensitive raw material having the requirement to dry at lower temperature. Thermal sensitive raw material having the requirement to dry at lower temperature. Being adapted the heating way of jacket and inner stirring at the same time, its heaat conducting area is large and its heat efficiency is high. Being installed stirring in the machine,it makes raw material in the cyliner form the state of continuous circle inside the cylinder.so the uniformity to be heated of raw material is raised greatly. Being installed stirring in the machine,pulpiness,paste-like mixture of powder raw material can be dried easy. It is an innovation horizontal batch-type vacuum dryer, The moisture of wet material will be evaporated by heat transmission. The stirrer with squeegee will remove material on hot surface and move in the container to form cycle flow. The evaporated moisture will be pumped out by vacuum pump
