Double cone rotary vacuum dryer
Working principle SZG double cone rotary vacuum dryer is a double cone rotary tank. Under the vacuum state, the tank is heated by passing thermal oil or hot water into the jacket, and the heat contacts the wet material through the inner wall of the tank. The water vapor or other gas evaporated after the wet material absorbs heat is sucked away by the vacuum pump through the vacuum exhaust pipe. Because the inside of the tank is in a vacuum state, and the rotation of the tank keeps the material up and down, turning inside and out, it speeds up the drying speed of the material, increases the drying rate, and achieves the purpose of uniform drying.
Features The 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 the solvent does not need to be recovered, the condenser may not be used.) This machine has advanced design, simple internal structure, easy cleaning, all materials can be discharged, and the operation is simple. Can reduce labor intensity and improve working environment. At the same time, the material also rotates when the container itself rotates, but no material accumulates on the wall, so the heat transfer coefficient is high and the drying rate is large, which not only saves energy, but also the material is evenly and fully dried and has good quality. Can be widely used in pharmaceutical, chemical, food, dyeing and other industries.
Scope of application This machine is suitable for vacuum drying and mixing of powder and granular materials in the pharmaceutical, food, chemical and other industries, especially for the following requirements:
※ High temperature sensitive materials cannot be accepted ※ Materials that need to recover solvents and toxic gases ※ Materials that are easy to be oxidized and dangerous ※ Materials that require crystals ※ Materials that require extremely low residual volatile content

The motor can be equipped with a speed-adjusting motor according to the user's requirements, and the speed is 0 ~ 6rpm. The above technical parameters are calculated according to 0.6g / c m3. If the liner material is glass-lined, it must be presented when ordering; if the material is flammable and explosive, it must be clearly stated when ordering, otherwise it is strictly prohibited.
※ The heating is divided into hot water and heat transfer oil.
※ When ordering, please indicate the temperature that the material can withstand or the temperature of the dryer, so that the factory can choose or provide you with a heat source.
※ When drying viscous materials, our factory will specially design a "copy board" structure in the tank.
※ The accessories involved in the vacuum drying system can be provided and installed by users in our factory, please specify in the order.
※ Our factory can provide design, manufacture and installation for the special requirements of users.
