The double cone rotary vacuum dryer is a double cone rotary tank body. In the vacuum state of the tank, steam or hot water is introduced into the jacket for heating. The heat is contacted with the wet material through the inner wall of the tank. The water vapor evaporated after the wet material absorbs heat is pumped away by the vacuum pump through the vacuum exhaust pipe. Due to the vacuum in the tank body, and the rotation of the tank makes the material constantly turn up and down inside and outside, so the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved. Working principle double cone rotary vacuum dryer is a new type of dryer which integrates mixing drying. The condenser, vacuum pump and dryer are matched to form a vacuum drying device. The machine is advanced in design, simple in structure, easy to clean, and easy to discharge all materials. It can reduce labor intensity and improve working environment. At the same time, because the materials rotate when the container rotates and there is no accumulation on the wall of the container, the heat transfer coefficient is high, the drying rate is large, the energy is saved, and the material is dried evenly and sufficiently with good quality. It can be widely used for drying materials in pharmaceutical, chemical, food, dye and other industries. It meets the requirements of GMP. Features 1. Reasonable design, convenient installation and debugging, can adapt to various conditions. 2. It is equipped with continuous protection device. 3. the energy consumption is only 30% GMP of the centrifugal spray dryer section of the same output, and the final moisture content of the material can be flexibly regulated. 5., the whole drying process is completed in a vacuum low temperature environment, which is consistent with the medical GMP standard and is suitable for heat sensitive materials. 6. High degree of automation, simple operation and continuous production. Scope of application: This machine is suitable for vacuum drying and mixing of powdery granular materials in medicine, food, chemical industry and other industries, especially for materials with the following requirements: 1. Heat sensitive materials cannot be accepted; 2. Easily oxidized and dangerous materials; 3. Materials requiring solvent and toxic gas recovery; 4. Materials requiring extremely low residual volatile matter content 5. Materials with requirements for crystal shape
