SZG Double Cone Rotary Vacuum Dryer is a double cone rotary tank, the tank in a vacuum state, to the jacket through the thermal oil or hot water for heating, heat through the inner wall of the tank and the wet material contact. The water vapour or other gases evaporated from the wet material after absorbing the heat will be pumped away by the vacuum pump through the vacuum exhaust pipe. As the tank is in a vacuum state, and the tank's rotation makes the material constantly up and down, inside and outside the flip, so it speeds up the drying speed of the material, improve the drying rate, to achieve the purpose of uniform drying.

Characteristics of equipment

Double cone rotary vacuum dryer is a new type of dryer integrating mixing and drying. The condenser, vacuum pump and dryer are matched to form a vacuum drying device. (If there is no need to recover the solvent, the condenser can not be used.) The machine has advanced design, simple internal structure, easy to clean, the material can be discharged, easy to operate. It can reduce the labour intensity and improve the working environment. At the same time because the container itself rotates when the material is also rotating, but the wall does not accumulate material, so the heat transfer coefficient is high, the drying rate is large, not only save energy, and the material drying is uniform and sufficient, good quality. It can be widely used in pharmaceutical, chemical, food, dyestuff and other industries.

Scope of application

This machine is suitable for vacuum drying and mixing of powder and granular materials in pharmaceutical, food, chemical and other industries, especially suitable for drying by the following requirements:
※ Heat-sensitive materials that cannot accept high temperature.
※ Materials that need to recover solvents and toxic gases.
※ Materials that are easily oxidised and dangerous
※ Materials with requirements for crystalline shape
※ Materials with very low content of residual volatiles.
